SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1229 PM CDT Wed Aug 09 2023 Valid 101200Z - 111200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE CAROLINAS AND SOUTHEASTERN VIRGINIA...AND OVER PORTIONS OF THE NORTHERN PLAINS/MID MISSOURI VALLEY AREA... ...SUMMARY... Strong to severe thunderstorms are possible across parts of the northern Plains, and from the Alabama vicinity to the coastal Carolinas/southeast Virginia on Thursday. ...Synopsis... Within the belt of moderate west-southwesterly mid-level flow across the U.S. Thursday, two short-wave troughs will be associated with two distinct areas of convective/severe potential. The first of these troughs is expected to cross the central and southern Appalachians region during the day, and then should move off the Mid-Atlantic/Carolina Coasts during the evening. Meanwhile, the second trough -- expected over the northern and central High Plains area early in the day --will move east-southeastward across the Plains through the afternoon, and to the Mid and Upper Mississippi Valley region by the end of the period. At the surface, a compact low/frontal system is forecast to cross the central and southern Appalachians region early, and then across Virginia and the Carolinas through the day. The front should clear the East coast from New Jersey southward through late afternoon/early evening, with the low then continuing across southern New England into the overnight hours. Meanwhile, a weaker low/trough is forecast to cross the Plains through the afternoon/evening hours. ...Parts of the Southeast and Mid-Atlantic regions... Thunderstorms -- possibly in the form of an at least loosely organized band -- will likely be ongoing at the start of the period across the western Carolinas vicinity. These storms may be accompanied by ongoing risk for locally damaging wind gusts, and possibly a tornado. Some decrease in intensity may occur with this convection into the afternoon, though indications are that subsequent storm redevelopment may occur across the southeastern Virginia/eastern Carolinas area during the afternoon, ahead of the advancing cold front. These storms would also likely pose a risk for damaging winds locally, along with potential for hail and a tornado or two before storms move offshore during the evening. ...Northern Plains and Mid-Missouri Valley area... Diurnal heating ahead of an advancing/weak cool front will result in moderate afternoon warm-sector destabilization across the central and northern Plains region. As the boundary advances in tandem with weak upper short-wave troughing, isolated to widely scattered storm development is expected by latter stages of the afternoon period. CAM output from various models differs, with respect to storm coverage, though several suggest upscale/linear growth with time, and possibly even an eventual southeastward-moving, bowing MCS across the Mid-Missouri Valley area during the evening and possibly into the overnight hours. In any case, with 35 to 45 kt mid-level west-northwesterlies across the area, atop low-level southerly warm-sector winds, shear will support potential for organized storms, and attendant risks for locally damaging wind gusts, and severe-caliber hail. A tornado cannot be ruled out, mainly across the eastern South Dakota vicinity where slightly backed low-level flow is anticipated ahead of the weak surface low. While storm coverage remains uncertain, current indications are that upgrade to SLGT risk is warranted for the afternoon and evening hours. ...Southern New England... As a deepening surface low crosses southern New England during the second half of Thursday, meager CAPE may support a few thunderstorms. Within the northeast quadrant of the low -- across southeastern New England -- a very favorable flow field is anticipated, with low-level winds veering/increasing rapidly with height. While the thermodynamic deficiency that is anticipated should substantially limit overall potential, conditional risk for a couple of stronger wind gusts and/or a tornado or two is evident, mainly from late afternoon through late evening, until the low and associated front sweep northeastward/offshore. ..Goss.. 08/09/2023 Read more

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0429 PM CDT Tue Aug 08 2023 Valid 101200Z - 161200Z ...Texas... Extremely dry and warm conditions, with daily highs 100+ F degrees, will continue across central and southern Texas through the extended period. While light rainfall will be possible across portions of southwest/north central Texas, much of central Texas will likely remain dry through D8. High pressure building in across the Four Corners to the Southern Plains will keep winds mostly light, though locally breezy conditions may occur. Elevated to locally Critical fire weather concerns will be likely daily, with low confidence in any one corridor where sustained winds will support Critical risk probabilities. Though the winds will largely stay below criteria, expect continued potential for new fire starts and rapid fire growth in hot and unstable conditions and extremely critically dry fuels. ...Dry Thunderstorms... Potential remnants of tropical storm activity will spread northward into California and southern Oregon beginning D3 - Thursday through D4 - Friday. Recent model runs have been slower and drier with northern extent of the incoming moisture. Initial activity across central/northern California will likely be isolated, with low potential for a dry thunderstorm or two. Potential for thunderstorms will increase into D5 - Saturday and D6 - Sunday as better instability spreads across northern California. A mix of wet/dry storms with gusty and erratic winds may be possible. Confidence in coverage remains too low to include any areas at this time but this will be monitored in the coming days. ..Thornton.. 08/08/2023 ...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 0257 PM CDT Tue Aug 08 2023 Valid 082000Z - 091200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS A PORTION OF THE CENTRAL HIGH PLAINS...FOCUSED ON THE NORTHEASTERN COLORADO VICINITY... ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE CENTRAL PLAINS REGION...AND OVER PORTIONS OF THE SOUTHEAST... ...SUMMARY... Scattered severe thunderstorm potential persists across parts of the central Plains during the late afternoon into tonight. Large to very large hail, severe gusts, and a tornado or two are possible. Scattered damaging winds and isolated severe hail will also remain possible through early evening across parts of the Southeast. ...Discussion... The MRGL risk area over southeastern New England is being removed in this update, as earlier storms have moved offshore, and any risk with subsequent convection should remain low. Otherwise, no changes appear to be needed to existing lines and associated forecast reasoning, as evolution of the scenario continues according to prior expectations. ..Goss.. 08/08/2023 .PREV DISCUSSION... /ISSUED 1130 AM CDT Tue Aug 08 2023/ ...Wyoming/northern Colorado to Central Plains... A prominent summertime shortwave trough will continue to advance southeastward over southeast Idaho/northern Utah into Wyoming today, with downstream height falls influencing the High Plains by evening. This scenario will enhance lee troughing, aiding a north-northwestward surge of low-level moisture through late afternoon/evening toward much of the Colorado Front Range and southeast Wyoming/Nebraska Panhandle. Initial high-based thunderstorm development is expected over the mountains/higher terrain of northern Colorado/southern Wyoming by mid-afternoon, with a subsequent increase/eastward spread, along with additional development into the larger buoyancy environment across the central High Plains including northeast Colorado/southwest Nebraska/northwest Kansas. Strengthening late-day westerlies (35-45 kt) will contribute to elongated, nearly-straight hodographs, while buoyancy with 2500-3000 J/kg MLCAPE should be maximized across northeast Colorado and southwest Nebraska. Splitting supercells are expected with a north/south-oriented cluster likely evolving relatively quickly as outflows consolidate towards the Colorado/Nebraska/Kansas border vicinity. The potential for a longer-track discrete supercell or two appears greatest along the southern periphery of convective development owing to lack of interference from other storms. Very large hail, significant severe wind gusts, and a tornado or two are all possible. A strengthening nocturnal low-level jet and enhanced warm/moist advection near/above the surface could help maintain or even reinvigorate the MCS east-southeastward into central/eastern Kansas overnight, with damaging wind potential and possibly some hail risk. ...Lower Mississippi Valley/Southeast... The leading edge of a residual MCS is ongoing across the Lower Mississippi Valley at late morning, with a considerable amount of trailing stratiform precipitation. Much of this MCS will continue to interface with the cooler/more stable side of the front that arcs roughly west-to-east across Louisiana/Mississippi/Alabama and Georgia, with some of the MCS-related cloud canopy extending across the downstream warm sector. But even a glancing influence of the MCS/any MCV and related outflows should contribute to at least isolated/widely scattered thunderstorm development near the front this afternoon as the boundary layer becomes moderately to strongly unstable, with upper 70s F warm-sector surface dewpoints common. Upstream WSR-88D VWP data (such as Fort Smith AR and Little Rock this morning) does sample a seasonally strong 50+ kt belt of westerlies between 3-8 km AGL, with the stronger winds grazing the frontal zone/adjacent warm sector. This is likely to support sustained/relatively organized multicellular clusters with scattered damaging winds as the most common hazard. ...New England... A relatively short duration severe risk may briefly linger early this afternoon across coastal southeast New England in association with a narrow warm/moist sector ahead of a secondary surface low, including the possibly of a localized wind damage and/or a brief tornado. Otherwise, convective development this afternoon is anticipated over western New England where deep-layer shear will be weak in closer proximity to the trough axis, with the potential for organized severe thunderstorm development expected to remain low. ...Northern Minnesota/eastern North Dakota... A shortwave trough over northern Manitoba and northwest Ontario will continue to dig southeastward, with a cold front settling southward across North Dakota/northern Minnesota through tonight. Thunderstorms should be focused along the front particularly late this afternoon through early evening. An adequate combination of deep-layer shear and instability should support an isolated severe wind/hail risk. Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0259 PM CDT Tue Aug 08 2023 Valid 091200Z - 101200Z ...CRITICAL FIRE WEATHER AREA FOR CENTRAL TO NORTH TEXAS... The current D2 Fire Weather Outlook remains on track with no updates needed. See previous discussion for more information. ..Thornton.. 08/08/2023 .PREV DISCUSSION... /ISSUED 0142 AM CDT Tue Aug 08 2023/ ...Synopsis... Fire weather concerns will persist across central to north Texas on Wednesday as a surface trough moves through the region and strengthens low-level winds. More localized concerns may emerge across parts of the Southwest and Great Basin. ...Texas... The upper trough currently approaching the central Rockies is forecast to slowly meander east into the mid-MS Valley by late Wednesday. As this occurs, an attendant surface trough trailing into central TX will migrate east. This will strengthen region pressure gradient winds, with ensemble guidance showing reasonably high probability for sustained 15-20 mph south/southwesterly winds. With exceptionally dry fuels already in place and temperatures exceeding 100 F expected by mid-afternoon, elevated to critical fire weather conditions are expected. There is some uncertainty regarding 1) the potential for wetting rainfall over the next 24 hours (and its impact on fuel status), and 2) the potential for isolated to scattered thunderstorms Wednesday afternoon along the surface trough. These storms may produce beneficial rain and modulate the overall fire threat, or could produce gusty outflow winds and locally exacerbate fire concerns. ...Southwest and Great Basin... More localized elevated fire weather conditions are expected across central NM and western to central NV. Across NM, 15-20 mph gradient winds in the wake of the surface trough are likely and should overlap with RH values in the teens to low 20s. However, recent rainfall has likely mitigated fuel status across this region. To the west, downslope flow in the lee of the Sierra Nevada may support localized elevated conditions across western/southern NV. Ensemble guidance suggests these conditions will remain fairly localized and confined to the immediate lee of the terrain. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

Day 2 Convective Outlook RESENT 1 NWS Storm Prediction Center Norman OK 0111 PM CDT Tue Aug 08 2023 Valid 091200Z - 101200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM SOUTHEASTERN MISSOURI AND NORTHEASTERN ARKANSAS INTO THE TENNESSEE VALLEY... ...SUMMARY... Severe thunderstorms are expected on Wednesday from eastern Oklahoma/Kansas eastward to the Lower Ohio and Tennessee Valley vicinity. ...Synopsis... A mid-level short wave trough, embedded in a belt of enhanced west-southwesterly flow across the central and eastern U.S., will advance steadily east-southeastward, crossing the Mid Mississippi Valley overnight. A belt of enhanced flow in the lower and middle troposphere (40 to 60 kt at mid levels) will spread across the Ozarks through the day, and across the Mid Mississippi Valley into the Ohio and Tennessee Valleys during the evening and overnight. At the surface, a cold front -- trailing from a weak low initially progged over eastern Kansas -- is forecast to shift eastward into the Ozarks and southeastern Oklahoma through the day, and then across the Mid Mississippi and Lower Ohio Valley overnight. By the end of the period, the front should extend from a low over the Ohio vicinity west-southwestward to North Texas. ...Eastern portions of KS/OK eastward into the Ohio Valley/Mid-South/Southeast... Expectations remain that fairly widespread convection will be ongoing at the start of the period across eastern Kansas and Missouri, which should shift eastward through the day into/across the Mid Mississippi/Lower Ohio/Tennessee Valleys. Very limited/local severe risk may be ongoing early, and should increase through the day as the airmass ahead of the convection destabilizes. Locally damaging winds should be the primary severe risk assuming storms intensify as expected, along with potential for hail and a tornado or two. Meanwhile, a second round of convection is forecast to develop in the recovering airmass across the Ozarks vicinity ahead of the advancing cold front during the afternoon/evening, with timing and initial intensity of the convection modulated by prior storms and any lingering cloud cover. Eventually, storms should intensify and grow upscale into one or more clusters -- aided by a 35-45 kt southwesterly low-level jet. At this time, it appears that overall risk for damaging winds -- potential from two separate rounds of storms -- warrants upgrade to ENH risk/30% wind probability across parts of the Mid Mississippi and Tennessee Valleys, which would continue well into the evening hours. ..Goss.. 08/08/2023 Read more
