SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0800 PM CDT Sat May 03 2025 Valid 040100Z - 041200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR SOUTHEAST AL...CENTRAL/NORTHERN GA...UPSTATE SC...AND ALSO FOR PARTS OF THE NORTHERN MID ATLANTIC... ...SUMMARY... Strong to severe storms remain possible tonight from the Southeast into parts of the Mid Atlantic and Northeast. ...Southeast into the Mid Atlantic/Northeast... A cluster of strong to locally severe storms is moving across parts of central/south AL into north GA this evening, generally along and just ahead of a cold front. Favorable ascent related to a midlevel cyclone anchored over the mid MS/lower OH Valleys may help to sustain these storms through part of the evening as they move eastward, with a threat of locally damaging gusts, localized hail, and possibly a tornado or two. Additional strong to locally severe storms may also continue this evening within a somewhat more moist and unstable environment from south AL into the FL Panhandle. There is some potential for strong storms to spread into the northern FL Peninsula overnight, within a relatively unstable and favorably sheared environment. From the Carolinas into the Mid Atlantic, multiple storm clusters are moving northeastward within a narrow axis of modest instability. Moderate deep-layer shear will continue to support occasionally organized convection and potential for isolated damaging wind and hail. A general weakening trend is expected with time through the evening across the Mid Atlantic, as remaining instability continues to diminish. Overnight across the Carolinas, a few strong storms may move in from the west and/or develop in place, aided by a modestly strengthening low-level jet. ...Far West Texas... A couple small but relatively organized cells are ongoing across Far West TX early this evening. MLCAPE of around 500 J/kg and sufficient deep-layer shear will continue to support potential for isolated strong storms through the evening, with isolated hail possible. ...Parts of NV/ID/OR... High-based convection has produced occasional strong to locally severe gusts across parts of NV through the afternoon. Steep low-level lapse rates could may continue to support localized severe-gust potential through the early evening, before the already meager buoyancy diminishes with the onset of nocturnal cooling. ..Dean.. 05/04/2025 Read more

MD 0673 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTH CAROLINA INTO SOUTH-CENTRAL NORTH CAROLINA
Mesoscale Discussion 0673 NWS Storm Prediction Center Norman OK 0536 PM CDT Sat May 03 2025 Areas affected...South Carolina into south-central North Carolina Concerning...Severe potential...Watch unlikely Valid 032236Z - 040030Z Probability of Watch Issuance...20 percent SUMMARY...Scattered thunderstorms will linger within an environment supportive of organized convection for the next couple of hours. Severe thunderstorm coverage and longevity is expected to remain sufficiently limited to preclude watch issuance. DISCUSSION...Across central SC, scattered thunderstorms continue to develop along the eastern flank of an expanding cold pool deposited by prior convection. Ahead of this boundary, temperatures are warming into the upper 70s and low 80s - a few degrees warmer than anticipated by some guidance - and southeasterly low-level flow is advecting low 60s dewpoints northward ahead of the ongoing convection. This is not only promoting slightly better buoyancy than depicted by guidance and recent mesoanalysis estimates, but is also maintaining a narrow warm sector ahead of the storms. Regional VWPs are sampling modest wind profiles with 0-6 km BWD values around 30 knots, which may promote periodic organization/intensification of ongoing convection with an attendant hail/damaging wind threat. A recent trend of cooling cloud-top temperatures over the past 30 minutes supports the idea that at least a low-end severe threat could materialize in the near term (next 1-2 hours). While sufficient for organized convection, deep-layer shear vectors are largely along the outflow boundary and/or into the residual cold pool. Consequently, this may limit storm longevity/intensity and should modulate the overall severe threat as this activity continues to propagate north/northeast into south-central NC. Additionally, the onset of nocturnal cooling in the coming hours should begin to diminish buoyancy and lead to an overall weakening trend after roughly 00 UTC. ..Moore/Thompson.. 05/03/2025 ...Please see www.spc.noaa.gov for graphic product...

Watch issuance is possible if severe thunderstorm coverage sufficiently increases. DISCUSSION...Scattered thunderstorms have begun developing across southwest AL into far southeastern MS as a cold front continues to push east/southeast into the region. Ahead of the front, broken cloud cover has allow temperatures to warm into the mid/upper 70s, which based on recent RAP forecast soundings, should be supporting MLCAPE values upwards of 1000-1500 J/kg with very limited inhibition. Regional VWPs are sampling somewhat straight hodographs with 0-6 km BWD values of around 40-45 knots, which is supportive of supercells capable of producing large hail (1.0 to 1.75 inches in diameter). However, recent radar trends show widespread new cell development with destructive storm interactions ongoing. This may limit the overall coverage of strong/severe storms. With time, upscale growth/storm interactions along the front should promote clustering with an attendant damaging wind threat across southeast AL and parts of the FL Panhandle. Convective trends will continue to be monitored, and watch issuance is possible if the coverage of severe storms continues to increase. ..Moore/Thompson.. 05/03/2025 ...Please see www.spc.noaa.gov for graphic product...

WW 221 SEVERE TSTM AL GA 032235Z - 040300Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 221 NWS Storm Prediction Center Norman OK 535 PM CDT Sat May 3 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of East central Alabama West central into north Georgia * Effective this Saturday afternoon and evening from 535 PM until 1000 PM CDT. * Primary threats include... Scattered damaging wind gusts to 70 mph possible Scattered large hail events to 1.5 inches in diameter possible A tornado or two possible SUMMARY...A line of storms with a history of some wind damage will continue eastward across north Georgia this evening. Farther south, the environment does support supercells capable of producing isolated large hail up to 1.5 inches in diameter and damaging gusts of 60-70 mph. An isolated tornado or two may occur with the supercells and/or embedded circulations in the line. The severe thunderstorm watch area is approximately along and 50 statute miles east and west of a line from 75 miles north northeast of Atlanta GA to 20 miles south of Montgomery AL. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU1). PRECAUTIONARY/PREPAREDNESS ACTIONS...

Valid 032246Z - 032345Z The severe weather threat for Severe Thunderstorm Watch 219, 220 continues. SUMMARY...A small organizing cluster of storms may pose increasing potential to produce strong to severe surface gusts across the Harrisburg PA vicinity into areas near/northwest of Philadelphia through 8-9 PM EDT. DISCUSSION...Within a modestly heated and well-mixed boundary layer, characterized by 20-25+ F surface temperature/dew points spreads and CAPE on the order of 500-1000 J/kg, scattered vigorous thunderstorm development continues. This is generally focused within weak surface troughing, beneath difluent upper flow across the northern Mid Atlantic vicinity. Deep-layer shear is moderately strong beneath 40 kt south-southwesterly flow around 500 mb, and this continues to support at least one isolated supercell now moving into the Greater Philadelphia area, accompanied by potential for marginally severe hail and locally strong surface gusts. Upstream, convection has consolidated into a small organizing cluster to the north and northwest of the Greater Washington D.C./Baltimore metro area. This activity could still pose increasing potential to produce produce strong to severe surface gusts while propagating across the Harrisburg vicinity and areas near/northwest of the Greater Philadelphia area through 00-01Z. ..Kerr.. 05/03/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0671 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR EASTERN ALABAMA INTO NORTHWEST GEORGIA
Mesoscale Discussion 0671 NWS Storm Prediction Center Norman OK 0434 PM CDT Sat May 03 2025 Areas affected...Eastern Alabama into northwest Georgia Concerning...Severe potential...Watch possible Valid 032134Z - 032330Z Probability of Watch Issuance...40 percent SUMMARY...A squall line developing across northeast to central Alabama may pose a damaging wind threat through the early evening hours. Watch issuance is possible if convective trends continue to increase. DISCUSSION...An organized squall line continues to develop across northeast to central AL as a cold front pushes into the region. Earlier cloud cover across the warm sector has begun to erode over the past hour or so, resulting in temperatures warming into the mid to upper 70s with a corresponding reduction in inhibition and increasing MLCAPE (upwards of 500-1000 J/kg per recent mesoanalysis estimates). The improving thermodynamic environment, coupled with 35-40 knots of deep-layer shear per regional VWPs, is supporting an overall uptick in convective intensity based on GOES IR imagery and MRMS echo tops. Lingering clouds and gradually diminishing diurnal insolation suggest that the thermodynamic environment is likely at its zenith, so the overall convective intensity remains somewhat uncertain heading into the late afternoon/early evening. Regardless, based on current observations, this squall line and embedded supercells should be sufficient to produce damaging gusts, occasional large hail, and perhaps embedded circulations where line segments can become meridionally oriented and more orthogonal to the southwesterly low-level shear vectors. Trends will continue to be monitored for the need for a watch. ..Moore/Thompson.. 05/03/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...MRX...FFC...BMX...HUN...
