WW 224 SEVERE TSTM FL CW 051815Z - 060100Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 224 NWS Storm Prediction Center Norman OK 215 PM EDT Mon May 5 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of The Eastern Florida Peninsula Coastal Waters * Effective this Monday afternoon and evening from 215 PM until 900 PM EDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2 inches in diameter possible Isolated damaging wind gusts to 70 mph possible A tornado or two possible SUMMARY...Scattered to numerous thunderstorms are expected to develop and strengthen this afternoon along and near the Atlantic Coast sea breeze. This activity should pose a threat for large hail up to 1-2 inches in diameter and isolated damaging winds. The severe thunderstorm watch area is approximately along and 35 statute miles east and west of a line from 10 miles east northeast of Daytona Beach FL to 40 miles south of Miami FL. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && OTHER WATCH INFORMATION...CONTINUE...WW 223... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 27015. ...Gleason Read more

MD 0702 CONCERNING SEVERE THUNDERSTORM WATCH 223... FOR FAR SOUTHEAST VIRGINIA AND EASTERN NORTH CAROLINA
Mesoscale Discussion 0702 NWS Storm Prediction Center Norman OK 0507 PM CDT Mon May 05 2025 Areas affected...Far southeast Virginia and eastern North Carolina Concerning...Severe Thunderstorm Watch 223... Valid 052207Z - 060000Z The severe weather threat for Severe Thunderstorm Watch 223 continues. SUMMARY...Thunderstorms developing along and ahead of a cold front/outflow boundary will continue to see periods of intensification to severe limits through early evening across eastern North Carolina and into far southeast Virginia. DISCUSSION...Over the past hour, discrete/semi-discrete cells across eastern NC and southeast VA have shown a slight downturn in overall intensity and organization based on reflectivity structure/intensity, MRMS echo top/vertical ice metrics, and cloud-top temperatures. For cells developing along an eastward propagating, storm motions along/slightly behind the boundary are likely responsible for this trend. Regardless, the overall convective environment across NC and southeast VA remains favorable for organized convection. Latest RAP mesoanalysis estimates continue to show MLCAPE values upwards of 1500 J/kg and surface-based lifted indices between -6 to -8 C across parts of eastern NC ahead of the boundary. Additionally, the MHX VWP continues to sample deep-layer shear on the order of 40 knots. GOES visible imagery shows agitated cumulus along and ahead of the boundary, suggesting that new cell development remains possible. The expectation for the next couple of hours is that ongoing convection may see an uptick in intensity as it pushes east/northeast further into the buoyant air mass, and new convection may develop along/ahead of the boundary across eastern NC with an attendant hail/wind risk. ..Moore.. 05/05/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0706 CONCERNING TORNADO WATCH 227... FOR PARTS OF SWRN TX AND ADJACENT SERN NM
Mesoscale Discussion 0706 NWS Storm Prediction Center Norman OK 0615 PM CDT Mon May 05 2025 Areas affected...parts of swrn TX and adjacent sern NM Concerning...Tornado Watch 227... Valid 052315Z - 060115Z The severe weather threat for Tornado Watch 227 continues. SUMMARY...Intensifying supercells possible, initially posing a risk for large hail in excess of 2 inches in diameter, then increasing potential for a couple of tornadoes, by 8-9 PM CDT. DISCUSSION...Boundary-layer moisture across the Pecos Valley remains largely characterized by relatively modest surface dew points in the middle 50s F, including an ongoing westward surge across and west/northwest of Fort Stockton. In the presence of very steep lower/mid-tropospheric lapse rates, this appears to be contributing to rapid destabilization, including CAPE increasing in excess of 2000 J/kg through this evening, east through north of the Davis Mountains into areas south of Hobbs NM. Beneath strong difluent mid/upper flow, to the east of a slow moving low over Arizona, deepening convective development is ongoing in the more strongly heated and deeply mixed environment to the west of the dryline. As this activity begins to acquire inflow of the more moist and increasingly unstable boundary-layer air, there appears potential for rapid intensification during the next few hours. The intersection of the dryline and a stalled frontal zone near/east of Wink may provide one focus for intensifying storms. As strengthening southeasterly low-level flow contributes to enlarged, clockwise curved low-level hodograghs beneath seasonably strong southerly mid/upper flow, this may include a supercell or two accompanied by increasing risk for a tornado, possibly strong. ..Kerr.. 05/05/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0705 CONCERNING SEVERE THUNDERSTORM WATCH 226... FOR NORTHERN OHIO
Mesoscale Discussion 0705 NWS Storm Prediction Center Norman OK 0556 PM CDT Mon May 05 2025 Areas affected...Northern Ohio Concerning...Severe Thunderstorm Watch 226... Valid 052256Z - 060030Z The severe weather threat for Severe Thunderstorm Watch 226 continues. SUMMARY...A line of thunderstorms migrating into northwestern parts of WW 226 may produce strong to severe winds and isolated hail, though it is not clear how long or far downstream this threat will persist. DISCUSSION...Reflectivity and velocity data from KCLE shows an organized, but compact, convective band developing across central/north-central OH. Wind velocities between 1-1.2 km above radar level were recently sampled at 35-45 knots, which suggests winds capable of producing damaging winds are likely embedded within the band. Environmentally, this line is on the periphery of any appreciable buoyancy and continues to migrate away from the better low-level moisture. However, a 35 knot 0-3 km wind shear vector sampled by the nearby KCLE VWP is nearly orthogonal to the line, and strong ascent associated with a vorticity maximum/shortwave trough aloft will continue to provide ascent and some degree of mid-level cooling/destabilization in the vicinity of the line. Consequently, this line may pose a damaging/severe wind and isolated hail threat into north-central OH. Eventually, diminishing buoyancy with northwest extent will lead to the demise of the band so downstream watch issuance is not expected (though local watch expansions have been made), but exactly when this occurs remains somewhat unclear. ..Moore.. 05/05/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0703 CONCERNING SEVERE THUNDERSTORM WATCH 224... FOR THE EAST-CENTRAL FLORIDA PENINSULA
Mesoscale Discussion 0703 NWS Storm Prediction Center Norman OK 0533 PM CDT Mon May 05 2025 Areas affected...the east-central Florida Peninsula Concerning...Severe Thunderstorm Watch 224... Valid 052233Z - 060030Z The severe weather threat for Severe Thunderstorm Watch 224 continues. SUMMARY...Thunderstorm development within a buoyancy maximum will likely result in a lingering severe hail and wind threat for the next 1-2 hours across the east-central Florida Peninsula. DISCUSSION...Scattered thunderstorm development along a convectively reinforced sea-breeze boundary has resulted in overturning of a buoyant air mass for much of the northern and southern east coast of FL. However, a relative minimum in convection across the central part of the east coast (roughly between Lake Okeechobee to Orlando, FL and eastward) has left a reservoir of 2000-2500 J/kg MLCAPE. Over the past 15-30 minutes, robust convection has developed along the sea-breeze boundary and is migrating into this CAPE maximum. 0-6 km BWD values behind the sea-breeze remain near 40 knots per the KMLB VWP, which will support supercells with an attendant risk for damaging winds and large hail, possibly up to the size of golf balls. This activity should persist for the next 1-2 hours before destructive storm interactions, convective overturning, and the onset of nocturnal cooling lead to a gradual reduction in the severe threat. ..Moore.. 05/05/2025 ...Please see www.spc.noaa.gov for graphic product...
