SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0453 PM CDT Mon May 27 2024 Valid 291200Z - 041200Z Fire weather concerns are expected to remain mostly low in the extended, with large-scale ridging expected over the western US. This will limit concerns over the Desert Southwest and High Plains where fuels are the driest. Elevated and spotty Critical fire weather concerns will be possible in lee of the higher terrain across central and southern New Mexico into portions of Arizona, where downslope breezes will overlap single digit relative humidity and very warm temperatures, mainly on D3/Wed. A small 40 percent delineation was added where confidence is highest in single digit relative humidity overlapping 10-15 mph sustained winds. Mid-way through the period D5/Friday, a trough across the Intermountain West will track into the Central Plains, with surface troughing strengthening again across the High Plains. Elevated to Critical fire weather may return across New Mexico into western Texas through the end of the period. Differences in long range model solutions on the overall height pattern and progression of any troughs leads to low confidence in the overall pattern and including areas at this time. ..Thornton.. 05/27/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

MD 1019 CONCERNING SEVERE THUNDERSTORM WATCH 334... FOR PARTS OF SOUTHEASTERN ALABAMA INTO CENTRAL AND SOUTHERN GEORGIA AND SOUTHERN SOUTH CAROLINA
Mesoscale Discussion 1019 NWS Storm Prediction Center Norman OK 0311 PM CDT Mon May 27 2024 Areas affected...parts of southeastern Alabama into central and southern Georgia and southern South Carolina Concerning...Severe Thunderstorm Watch 334... Valid 272011Z - 272145Z The severe weather threat for Severe Thunderstorm Watch 334 continues. SUMMARY...The severe threat continues across Severe Thunderstorm Watch 334. Strong thunderstorms should persist through the afternoon with a hail/damaging gust threat. DISCUSSION...Multiple multicells and transient supercells continue to develop and track east-southeast amid a strongly unstable environment, characterized by 3000+ J/kg MLCAPE per 20Z mesoanalysis. Regional VADs depict hodographs with modest curvature and elongation, suggesting that storms should remain mainly multicellular through the afternoon. Given strong buoyancy and modest deep-layer shear in place, wet downbursts within the stronger multicells and especially transient supercells may pose a damaging gust threat. Some hail may also occur, especially with the transient supercells. ..Squitieri.. 05/27/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1017 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR PORTIONS OF NORTH/CENTRAL TX
Mesoscale Discussion 1017 NWS Storm Prediction Center Norman OK 0204 PM CDT Mon May 27 2024 Areas affected...portions of north/central TX Concerning...Severe potential...Watch likely Valid 271904Z - 272130Z Probability of Watch Issuance...80 percent SUMMARY...Isolated thunderstorms are expected to develop by late afternoon. Very large hail in the 2.75 to 4 inch diameter range will be possible along with strong gusts. A severe thunderstorm watch will likely be needed in the next couple of hours. DISCUSSION...A roughly west to east oriented surface boundary is noted across north Texas this afternoon. To the south of this boundary, surface dewpoints in the mid to upper 70s are prevalent. Strong heating into the 90s F of this very moist boundary-layer and very steep midlevel lapse rates is supporting strong to extreme destabilization (MLCAPE 2500-4000 J/kg). Visible satellite has shown an increase in coverage of cumulus over the region, with areas of vertical development along the boundary and within a band of low-level confluence to the southwest of the Metroplex. While large-scale ascent will remain somewhat modest, increasing thunderstorm activity across northeast Mexico and increase in midlevel moisture impinging on south-central TX per latest water vapor imagery suggests some modest ascent is increasing over the region. Once convection deepens sufficiently, updrafts will likely grow vigorously given large instability and very steep midlevel lapse rates. Vertical shear will support supercells, with long/straight hodographs within this thermodynamic environment favoring very large hail. Locally strong to severe gusts may also accompany the strongest cells. Timing and coverage of severe storms is still a bit uncertain, but expected storms to develop by around 4pm CDT. While coverage may be sparse, potential for significant hail will likely require a watch issuance in the next couple of hours. ..Leitman/Guyer.. 05/27/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1018 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR PORTIONS OF CENTRAL TX
Mesoscale Discussion 1018 NWS Storm Prediction Center Norman OK 0248 PM CDT Mon May 27 2024 Areas affected...portions of central TX Concerning...Severe potential...Watch likely Valid 271948Z - 272115Z Probability of Watch Issuance...80 percent SUMMARY...Isolated severe thunderstorms producing large hail and strong gusts will be possible into early evening. DISCUSSION...Strong heating to near 100 F has allowed for some mixing of stronger boundary-layer dewpoints over portions of the area. However, dewpoints generally still remain in the 60s F. Very steep midlevel lapse rates also are in place. This is supporting moderate to strong instability within a strongly sheared environment. Furthermore, visible satellite imagery shows deepening/vertically developing cumulus across the MCD area. Forecast soundings depict deep mixing with inverted-v low-level thermodynamic profiles. Given a dry EML, this may support sporadic severe gusts. Furthermore, elongated/straight hodographs suggest large hail will be possible. Convection has already develop across northeast Mexico and will approach the Rio Grande in the next few hours. This convection also will pose a severe risk if it is maintained across the Rio Grande into TX. Some uncertainty exists regarding coverage and eastward extent of severe potential, but at least a narrow corridor of large hail and strong gust potential is expected. A watch will likely be needed in the next hour or so. ..Leitman/Guyer.. 05/27/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FWD...CRP...EWX...SJT...

WW 336 SEVERE TSTM TX 272050Z - 280300Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 336 NWS Storm Prediction Center Norman OK 350 PM CDT Mon May 27 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of North and Central Texas * Effective this Monday afternoon and evening from 350 PM until 1000 PM CDT. * Primary threats include... Scattered large hail likely with isolated very large hail events to 3.5 inches in diameter possible Scattered damaging winds and isolated significant gusts to 75 mph possible A tornado or two possible SUMMARY...Thunderstorms are expected to quickly develop and intensify through late afternoon and early evening within a moist and extremely unstable environment.
