SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0246 PM CDT Fri Oct 06 2023 Valid 081200Z - 141200Z Broad upper troughing should persist across the eastern CONUS through early next week, supporting a deep-layer northwesterly flow regime across the central/northern Plains into the Upper MS Valley, and overall cooler conditions from the OH Valley eastward. From mid to late next week, another mid-level trough amplifies over the Rockies and ejects into the Plains states, supporting surface cyclone development and a rapid return of low-level moisture from the central/southern Plains into the Southeast. Current medium range guidance consensus suggests that potentially dry and windy conditions may accompany the next amplifying mid-level trough across portions of the Interior West into the southern High Plains mid to late next week. However, fuel receptiveness is not overly robust at the moment, and questions remain whether this will change next week, precluding fire weather highlights this outlook. Dry conditions should persist across the Southeast Days 3-6/Sunday-Wednesday. However, guidance shows a diffuse surface pressure gradient prior to surface cyclone arrival, resulting in a weak synoptic wind field, keeping wildfire-spread potential localized. ..Squitieri.. 10/06/2023 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0207 PM CDT Fri Oct 06 2023 Valid 071200Z - 081200Z The previous forecast (see below) remains generally on track. The primary change made to this outlook was to expand the Elevated area farther northeast into eastern GA and northwestern SC. Here, the latest guidance consensus depicts up to 15 mph sustained northwesterly winds overlapping with 20-30 percent RH for at least a few hours tomorrow afternoon behind the surface cold front. Fuels are also at least modestly receptive to wildfire spread. There is some question regarding the robustness of wildfire-spread potential across portions of western into central LA, which has received 1-2 inches of rain within the past 48 hours. Still, the extent of the ongoing drought and rapid drying of finer grasses may still support appreciable fire spread. ..Squitieri.. 10/06/2023 .PREV DISCUSSION... /ISSUED 0159 AM CDT Fri Oct 06 2023/ ...Synopsis... A highly amplified large-scale trough will shift slowly eastward from the Ohio Valley toward the Northeast, while an expansive surface anticyclone moves southward across the central/southern Plains -- in the wake of a southeastward-moving cold front over the Gulf of Mexico. ...Central Gulf Coast and Southeast... Along the southeastern periphery of the surface anticyclone, an enhanced pressure gradient will favor 10-15 mph sustained northerly surface winds across the central Gulf Coast and Southeast. These breezy post-frontal winds, combined with 25 percent minimum RH, will support elevated fire-weather conditions. While rainfall is expected across parts of the area on Day 1/Friday, ongoing severe to exceptional drought and 80th-90th percentile ERCs suggest fuels will still be receptive to fire spread. ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0336 PM CDT Thu Oct 05 2023 Valid 071200Z - 131200Z Fire weather potential is expected to generally be low through the extended period with the exception of the Southeast region this weekend. Long-range guidance shows reasonably good agreement in the evolution of the synoptic regime over the weekend and into next week. The longwave trough currently over the central CONUS is forecast to shift east over the weekend and slowly deamplify over the Great Lakes through early next week. Upper ridging will remain in place across the western half of the country with a broad northwesterly flow regime across the Plains. This synoptic regime will favor cool, dry conditions east of the Rockies and warm conditions across the Southwest/West Coast. Fuels may undergo drying across the Southeast and Southwest where ensemble guidance shows low probability for substantial precipitation until the middle of next week. ...D3/Saturday - Southeast... Fire weather concerns may emerge across the Southeast states on D3/Saturday as a dry offshore flow regime becomes established behind a cold frontal passage on Friday. While some spread is noted in deterministic solutions, ensemble output hints at widespread gradient winds between 15-20 mph from southern MS to central GA. Additionally, a dry continental air mass advecting into the region should promote RH reductions into the 20s, resulting in areas of elevated (to perhaps locally critical) fire weather conditions. Confidence in such conditions is highest across southeast AL into southwest GA and the FL Panhandle, but may extend into much of AL, GA, and western MS based on a few drier/windier solutions. Recent fuel analyses place ERC values near the 80th to 90th percentile, suggesting fuels should support the fire weather concerns. ...D6/Tuesday and D7/Wednesday - Southwest and Southern High Plains... Most long-range solutions show a low-amplitude upper trough migrating into the Four Corners region by the middle of next week as the upper ridge breaks down. This will promote surface pressure falls across the Four Corners and central/southern High Plains D6/Tuesday into D7/Wednesday. Strengthening low-level flow coupled with antecedent dry conditions may support fire weather concerns on both of these days. However, considerable spread is noted in deterministic solutions regarding the placement and magnitude of the upper wave. Likewise, ensemble guidance shows only a modest signal for critical fire weather conditions despite the generally favorable synoptic regime. This uncertainty, coupled with recent rainfall over the southern High Plains and much of the Rockies, precludes introducing any risk areas. ..Moore.. 10/05/2023 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0252 PM CDT Thu Oct 05 2023 Valid 052000Z - 061200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms appear unlikely through the remainder of the Day 1 period. An outflow-reinforced boundary continues to push rapidly southward across Deep South TX, near the US/MX border at 20Z. Given the very moist air mass across the region, elevated instability will continue to support scattered storms, but strong to severe gust potential will be reduced as the outflow undercuts the remaining areas of warmer surface air. As such, wind probabilities have been removed for the remainder of the period. Elsewhere, weak/shallow convection over the Upper Great Lakes region in association with cold air beneath the upper trough is forecast to dwindle with the loss of heating later this afternoon, and as cooler/drier air pushes in from the west. ..Jewell.. 10/05/2023 .PREV DISCUSSION... /ISSUED 1121 AM CDT Thu Oct 05 2023/ ...Deep South TX... Convection has largely moved offshore this morning, but a slow-moving, small cluster persists over a portion of the Brush Country along a composite outflow-enhanced cold front moving south. Very rich western Gulf moisture characterized by 75-80 F surface dew points remains prevalent ahead of the front with ample insolation. This may support an uptick in thunderstorm intensity and coverage for a few hours centered on mid to late afternoon. While the combination of deep-layer shear and mid-level lapse rates will remain modest, there will be potential for 45-60 mph gusts in a couple multicell clusters approaching the Lower Rio Grande Valley.

MD 2234 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR PORTIONS OF CENTRAL TX
Mesoscale Discussion 2234 NWS Storm Prediction Center Norman OK 0702 PM CDT Wed Oct 04 2023 Areas affected...portions of central TX Concerning...Severe potential...Watch likely Valid 050002Z - 050130Z Probability of Watch Issuance...80 percent SUMMARY...Several cluster of storms including a few supercells should continue east/southeast with a risk for damaging winds and hail. A new WW or local extensions of existing watches are being considered. DISCUSSION...Across portions of north-central TX, ongoing convection has slowly grown upscale into a few, more defined clusters over the last couple of hours. Previous storms over OK and north TX have pushed an effective outflow boundary south of the Red River to just north of I-20. Along and south of the boundary, the air mass remains quite unstable (1500-2000 J/kg) of MLCAPE owing to the upper 60s to low 70s F surface dewpoints. Area VADs also show the air mass remains moderately sheared, sufficient for organized severe storms. Given the recent upscale growth trends, further growth of the clusters is expected with time. Damaging winds appear to be the most likely severe threat given the potential for strong updrafts and the more linear structures. However, with some potential for supercells and the moderate buoyancy, isolated hail will also remain possible. The greatest severe risk appears to be focused along the I-20 corridor through the next several hours, though storms may eventually take on a more southeastward motion as outflow consolidates. Given the relatively pristine air mass ahead of the ongoing storms, severe potential should increase this evening. A new WW and/or extensions of the existing watches are being considered. ..Lyons/Guyer.. 10/05/2023 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...SHV...FWD...SJT...

MD 2233 CONCERNING SEVERE THUNDERSTORM WATCH 703...704... FOR NORTHWEST/SOUTHWEST/WEST-CENTRAL TX
Mesoscale Discussion 2233 NWS Storm Prediction Center Norman OK 0606 PM CDT Wed Oct 04 2023 Areas affected...Northwest/Southwest/West-Central TX Concerning...Severe Thunderstorm Watch 703...704... Valid 042306Z - 050100Z The severe weather threat for Severe Thunderstorm Watch 703, 704 continues. SUMMARY...Threat for large to very large hail and damaging gusts will continue for at least the next few hours. DISCUSSION...Outflow-augmented cold front extending from far northwest TX into the Permian Basin continues to progress gradually southward/southeastward. Thunderstorms persist along this boundary, supported by ample buoyancy and low-level convergence. Given the abundance of storms and close storm proximity, a supercell-in-cluster storm mode currently prevails, with the strongest updrafts north of the composite outflow/cold front. Even with most storms north of the boundary, there does appear to be a more outflow-dominant structure to the pair of updrafts over Baylor and King Counties in northwest TX. Warm, moist, and buoyant conditions exists downstream of these updrafts, with steep low-level lapse rates in place as well. Development into an organized convective line appears probable, and the overall expectations is that some severe potential will persist for at least the next few hours into western portions of north TX. Further south and west into the Permian Basin and southwest TX, a more cellular storm mode dominants. Long hodographs have supported splitting supercells capable of large hail thus far, which should remain the primary risk for at least the next few hours. Strong gusts will also remain possible, particularly with the supercell currently in Scurry County. ..Mosier.. 10/04/2023 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0329 PM CDT Wed Oct 04 2023 Valid 061200Z - 121200Z A strong upper trough/low will develop late this week across the upper Midwest and Northeast. In the West and High Plains, upper-level ridging will build. Surface high pressure will cover much of the CONUS behind a cold front through part of the upcoming weekend. Model guidance does show a trough approaching the Northwest by early next week, but the timing and evolution of this trough and associated surface features is uncertain. Surface high pressure into the Great Basin and Northwest will drive some dry offshore winds in parts of northern and southern California into the weekend. Given the state of fuels in these areas, only locally elevated conditions are expected. Some dry and windy conditions are also possible in the West as the trough moves into the interior, but, again, fuels are currently not receptive and are not expected to become critically dry in the near future. Depending on the evolution of the next trough early next week, some high pressure may build into the Northwest and Great Basin. Additional offshore winds would then be possible around the middle /end of next week in southern California. Uncertainty remains high this far in advance. ..Wendt.. 10/04/2023 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0257 PM CDT Wed Oct 04 2023 Valid 042000Z - 051200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER MUCH OF NORTHWEST TEXAS ACROSS THE RED RIVER VALLEY AND INTO PARTS OF SOUTHERN OKLAHOMA... ...SUMMARY... Scattered to numerous severe thunderstorms are expected through early morning across parts of the southern Great Plains. Destructive, very large hail and a few significant severe wind gusts will be the main threats. Any tornado risk is expected to be brief. ...Much of western TX into southern OK... Scattered severe storms likely producing large hail have already developed across parts of the TX Panhandle and South Plains, with a few cells now moving into southwest OK. A front continues to drift southward across central OK and the TX Panhandle, with pressure falls noted within the surface trough. The greatest potential for particularly damaging hail appears to be located from northwest TX into southern OK through this afternoon and into the evening, as storms ride east/northeast along the boundary. The deepening moist layer, even with weak low-level winds, will provide favorable storm relative inflow for long-lived severe storms given moderate steering currents aloft. This, combined with additionally favorable mid to high level wind shear/elongated hodographs, suggest a storm or two could produce long swaths of significant hail. Additional severe storms producing hail will still be possible north of the boundary, as pockets of heating continue, and the air mass remains sufficiently unstable. The northeasterly boundary-layer winds north of the boundary may yield one or more left-moving cells. Other severe storms producing hail and damaging gusts are likely across much of West and western-North TX where the air mass continues to heat well ahead of the southward-moving front, including the area from Ft. Stockton/Midland northeastward toward Abilene. ..Jewell.. 10/04/2023 .PREV DISCUSSION... /ISSUED 1130 AM CDT Wed Oct 04 2023/ ...Southern Great Plains... Confidence continues to increase with potential for a significant severe weather episode across north/west TX and south OK this afternoon into tonight, yielding expansion of the cat 3 severe risk. The northern extent of a rather rich western Gulf air mass has spread across much of north TX and southwest to east OK, characterized by upper 60s to low 70s surface dew points. Moderate boundary-layer heating coupled with the rich moisture will yield a broad plume of 2000-3000 J/kg MLCAPE by late afternoon. Elevated thunderstorms may continue to shift east into northeast OK while renewed development across the TX Panhandle will probably intensify by early afternoon as it transitions to surface-based development along the southward-sagging composite cold front/large-scale outflow. Scattered thunderstorm development is also anticipated southward into the Trans-Pecos as low-level convergence/upslope increases near the dryline. A lack of surface cyclogenesis will result in relatively weak low-level mass response and correspondingly small low-level hodographs this afternoon in the warm sector. However, substantial speed shear above 700 mb will yield relatively straight and highly elongated mid to upper-level hodographs favoring splitting supercells with initial storm development. These initial supercells will be capable of producing very large to giant hail from 2-3.5 inches, mainly across west TX where steeper mid-level lapse rates and discrete supercell mode will persist longer. Farther north and east, consolidating outflow interactions and minimal convective inhibition will likely result in quicker upscale growth into clusters and bowing line segments by late afternoon/early evening as storm coverage becomes widespread. Still, given the favorable hodographs for strong mid-level rotation, longer-track embedded supercells will be possible, especially along the composite front/outflow across south OK initially, and over western north TX later. These may yield destructive wind-driven hail swaths with localized gusts reaching 75-85 mph. A large MCS is anticipated this evening, moving east-southeast over north/northeast TX with a decreasing severe wind risk overnight. Read more
