Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0358 AM CDT Tue Aug 27 2019 Valid 301200Z - 041200Z ...DISCUSSION... ...Days 4/5 - Fri/Sat -- Central and Southern Plains Vicinity... At least some potential for strong to severe storms appears possible heading into the weekend as a stalled cold front in the vicinity of southern NE/northern KS progresses southward as an upper shortwave impulse shifts southeast across the northern Plains and Upper Midwest. Southerly low level flow will continue to bring rich Gulf moisture northward across the southern/central Plains. At this time, aside from the surface boundary, forcing for ascent appears weak as does forecast shear. Guidance also varies in location/timing and extent of convection. As a result, uncertainty is too great to include severe probabilities at this time. ...Days 5/6 - Saturday/Sunday -- Southeastern U.S... By late Saturday into Sunday, some guidance brings current Tropical Storm Dorian toward Florida. Depending on the exact track, this could bring an attendant tropical cyclone tornado threat to portions of the southeastern U.S. Trends will be monitored closely along with future collaboration with the National Hurricane Center to address any possible threats approaching the mainland U.S. in the coming days. ...Days 7/8 - Monday/Tuesday -- Northern/Central Plains to the Upper Midwest... By the end of the period, forecast guidance brings a shortwave trough across the northern Rockies toward the northern Plains. A strengthening lee surface low over the northern High Plains and attendant cold front will shift east/southeast and could be a focus for severe potential early next week. Questions remain regarding moisture return this far north as well as timing differences in the arrival of the trough and surface cold front. As such, confidence is too low to introduce severe probabilities. Read more

MD 1879 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR FAR NORTH-CENTRAL TX
Mesoscale Discussion 1879 NWS Storm Prediction Center Norman OK 0355 AM CDT Tue Aug 27 2019 Areas affected...Far North-Central TX Concerning...Severe potential...Watch unlikely Valid 270855Z - 271030Z Probability of Watch Issuance...20 percent SUMMARY...Isolated damaging wind gusts are possible far north-central TX but the ongoing storm cluster is expected to weaken, keeping the threat isolated and precluding the need for a downstream watch. DISCUSSION...Recent gusts around 45-50 mph have been reported with the surging storm cluster across far south-central OK. Current storm motion on this cluster is south-southeastward at 38 kt. This cluster is already near the edge of Severe Thunderstorm Watch 625 along the TX/OK border. Downstream air mass across far north-central TX is characterized by temperatures in the low to mid 80s, dewpoints in the low to mid 70s, and strong buoyancy. RAP forecast soundings also show a deep warm layer and strong convective inhibition. While this cluster is currently quite strong (with 55 dbz over 30kft), the strong downstream convective inhibition is expected to lead to gradual storm weakening. Isolated strong wind gusts are possible with this cluster but the expected weakening limits the spatial and temporal extent of this threat. As such, a downstream watch across far north-central TX is not currently anticipated. ..Mosier/Grams.. 08/27/2019 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FWD...OUN...

SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0230 AM CDT Tue Aug 27 2019 Valid 291200Z - 301200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... The probability of severe thunderstorms on Thursday is low, though a few strong storms are possible across portions of the upper Great Lakes into the central Plains during the afternoon and overnight hours. ...Synopsis... A shortwave trough will migrate across the Great Lakes on Thursday. This will bring a belt of strong northwest flow across the Upper Midwest and Great Lakes vicinity. At this surface, moisture will return northward across the southern/central Plains and Ozarks toward IA and WI ahead of a cold front. A narrow warm sector will reside ahead of the front across southern WI into IA and northern IL. Guidance varies, but at least isolated thunderstorms are expected to develop by late afternoon or evening across parts of southern WI, with southward development into IA/IL more uncertain due to capping concerns and weaker forcing with southward extent. Thunderstorms will shift eastward into lower MI during the evening/overnight hours as the front progresses eastward. Additional development is possible across parts of IL into MO overnight as the front drops southward. If this occurs, convection would likely be elevated, limiting severe potential. Warm advection atop the western, stalled portion of the front across northern KS into NE also is possible overnight into Friday morning. However, it is unclear if this convection could pose a severe threat. While lapse rates are forecast to be steep, storm mode likely would not favor an elevated large hail threat due to clusters/line segments being the preferred mode. Overall, severe potential appear too conditional and/or uncertain to include probabilities at this time, though some strong storms are possible across parts of southern WI into lower MI as well as across northern KS into NE and trends will be monitored for possible upgrades in subsequent outlooks. ..Leitman.. 08/27/2019 Read more

Valid 270715Z - 270815Z The severe weather threat for Severe Thunderstorm Watch 625 continues. SUMMARY...Strong wind gusts and isolated large hail remain possible across western and central OK. DISCUSSION...Outflow boundary from earlier thunderstorms has pushed into far northwest TX/far north TX. Isentropic ascent driven by strong low-level jet from southwest TX into far southwest OK across this boundary continues to force new thunderstorm development across central and western OK. These storms, which are initially elevated, have quickly develop a cold pool and are now surging southward. Continued southward progress is anticipated for the next few hours Strong wind gusts are the primary severe threat although large hail is also possible with any new updrafts or as a result of updraft intensification due to storm mergers. ..Mosier.. 08/27/2019 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0208 AM CDT Tue Aug 27 2019 Valid 281200Z - 291200Z ...Synopsis... The upper-level ridge across the western CONUS will slowly shift eastward during the D2/Wednesday period. A slight breakdown of the ridge is forecast to occur as a weak shortwave trough approaches the Pacific Northwest. Moisture influx into the Intermountain West from a remnant tropical system as well as the Monsoon will support thunderstorm development over a broad area. The main areas of concern will be across portions of northwest Arizona into the central Great Basin, northern California, and much of western/central Oregon. PWAT values around 0.8 inches and relatively slow storm motions will mean potential for some wetting rainfall. However, fuels have cured with recent hot/dry conditions which will support ignitions. Holdover potential will also exist with the expected return of hot/dry conditions. ..Wendt.. 08/27/2019 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

MD 1877 CONCERNING SEVERE THUNDERSTORM WATCH 625... FOR EAST-CENTRAL OK...WEST-CENTRAL AR
Mesoscale Discussion 1877 NWS Storm Prediction Center Norman OK 0155 AM CDT Tue Aug 27 2019 Areas affected...East-Central OK...West-Central AR Concerning...Severe Thunderstorm Watch 625... Valid 270655Z - 270830Z The severe weather threat for Severe Thunderstorm Watch 625 continues. SUMMARY...Threat for damaging wind gusts will continue across east-central OK and west-central AR for the next few hours. A downstream watch across far southeast OK and southern AR is not currently anticipated. DISCUSSION...Radar trends over the past hour or so showed a forward surge with the convective line across east-central OK/west-central AR, with storm motion around 40 kt. More recent trends reveal a slowing of this forward surge, with storm motion now closer to 30-35 kt. Several strong wind gusts were measured recently in east-central OK, the strongest of which was 43 kt at GZL. Outflow appears to have outrun much of the deep convection along the central OK/AR, suggesting the system may be struggling to remain organized. Downstream air mass is characterized by ample low-level moisture and strong buoyancy. Strong convective inhibition exists but the well-developed cold pool will likely continue to force deep convection. Isolated strong wind gusts will remain possible over the next hour or two. This line is expected to move out of the watch around 08Z. Given that strong wind gusts are expected to become increasingly isolated, a downstream watch is not currently anticipated. ..Mosier.. 08/27/2019 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0118 AM CDT Tue Aug 27 2019 Valid 271200Z - 281200Z ...NO CRITICAL AREAS... ...Synopsis... An upper-level ridge will shift eastward over the West Coast while amplifying slightly today. Hot/dry conditions are expected much of the areas west of the Continental Divide. At the surface, high pressure over the central Rockies/High Plains in combination with a thermally-driven surface trough along the west coast of Oregon will drive easterly downslope flow for much of western Oregon. Some locations may see afternoon RH below 20%, but most areas will likely fall between 20-35%. Winds will generally be light (10-15 mph). However, areas near the Columbia Gorge in the northern Willamette Valley could see terrain enhanced flow of 15+ mph. As the spatial extent of elevated conditions is expected to remain small, no areas will be introduced. A few lightning strikes may occur along and just into the eastern slopes of the Sierra in central California. There is currently too much uncertainty as to whether these storms will impact areas outside of the highest peaks for greater fire weather concerns. ..Wendt.. 08/27/2019 ...Please see www.spc.noaa.gov/fire for graphic product...
