Severe Storms

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0800 PM CDT Thu Jun 19 2025 Valid 200100Z - 201200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE NORTHERN PLAINS AND UPPER MISSISSIPPI VALLEY... ...SUMMARY... Scattered severe thunderstorms with large to very large hail and damaging wind gusts are expected across the northern Plains and upper Mississippi Valley this evening into tonight. Isolated severe gusts will also be possible from central and eastern North Carolina north-northeastward to New England. ...Northern and Central Plains/Upper Mississippi Valley... Latest water vapor imagery at mid-levels shows a ridge over the High Plains, with west-northwesterly flow over much of the central and northern Plains. At the surface, a 1002 mb low is located over north-central South Dakota, with a trough extending south-southwestward into northwest Kansas. An axis of low-level moisture is analyzed from central Plains northward to near the surface low and northwestward into western North Dakota. Along this corridor, the RAP has MLCAPE mostly in the 2000 to 3000 J/kg range. A severe storm is currently ongoing near the instability max in southwest North Dakota, with additional isolated severe storms located in north-central Nebraska and northwest Kansas. Moderate deep-layer shear is present across much of the central and northern Plains, which will contribute to an environment supportive of supercells this evening. A severe threat with more longevity is expected in the northern Plains. The Bismarck 00Z sounding has a 0-6 km shear around 40 knots, with nearly dry adiabatic low to mid-level lapse rates. This will support supercells with large to very large hail, possibly greater than 2 inches in diameter. This, combined with surface dewpoints in the lower 60s F and substantial directional shear from the surface to 700 mb, will also support an isolated tornado threat. Concerning future convective development, the latest HRRR maintains a widely spaced coverage for much of the early to mid evening, but then begins to increases thunderstorm coverage over eastern parts of the northern Plains late this evening. As the nose of a low-level jet moves into the eastern Dakotas, a cluster of severe storms is expected to develop and move eastward into the upper Mississippi Valley tonight. Supercells with large hail will be possible with cells than remain discrete. However, linear mode should become favored, which will likely support an increase in the potential for severe gusts. ...Eastern States... A mid-level trough is currently evident on water vapor imagery over the southern and central Appalachians. Ahead of the trough, a moist airmass is present from the Carolinas north-northeastward into New England. The RAP suggests that instability is weak along and ahead of the surface trough. Short-term model forecasts suggest that scattered convective coverage will continue over the next few hours. 00Z soundings across the region show moderate deep-layer shear and have steep lapse rates around 850 mb. This should support an isolated severe threat over the next couple of hours as low-level flow gradually increases. Severe wind gusts will be the primary threat, associated with short bowing line segments. ..Broyles.. 06/20/2025 Read more

MD 1374 CONCERNING SEVERE THUNDERSTORM WATCH 443... FOR WESTERN TO CENTRAL MAINE
Mesoscale Discussion 1374 NWS Storm Prediction Center Norman OK 0559 PM CDT Thu Jun 19 2025 Areas affected...Western to central Maine Concerning...Severe Thunderstorm Watch 443... Valid 192259Z - 200100Z The severe weather threat for Severe Thunderstorm Watch 443 continues. SUMMARY...An intense line segment and a few developing supercells will continue to pose a severe hail/wind risk for the next 1-2 hours across western to central Maine. DISCUSSION...Recent GOES imagery shows intensifying updrafts within a convective band across northwest/western ME, as well as the development of a couple of supercells across west-central ME over the past hour. This is occurring as the band and weak mid-level ascent impinge on a buoyancy axis spanning from New England into northwestern ME. This corridor of 1000-1500 J/kg MLCAPE is fairly narrow based on visible imagery with stable billow clouds noted across central ME where temperatures remain in the low 70s. As such, the potential for severe hail/wind gusts will likely be most widespread over the next couple of hours before convection moves into the more stable air mass. However, well-established mesocyclones, such as the one embedded within the convective line, will continue to pose at least an isolated severe threat through 03 UTC across the eastern extent of WW 443. ..Moore.. 06/19/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 1373 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR NORTHERN NORTH CAROLINA AND FAR SOUTHERN VIRGINIA
Mesoscale Discussion 1373 NWS Storm Prediction Center Norman OK 0530 PM CDT Thu Jun 19 2025 Areas affected...Northern North Carolina and far southern Virginia Concerning...Severe potential...Watch possible Valid 192230Z - 200030Z Probability of Watch Issuance...60 percent SUMMARY...A bowing line segment will likely pose a severe wind risk along the North Carolina/Virginia border region over the next few hours. Watch issuance is probable if the band remains south of WW 442. DISCUSSION...A convective cluster has quickly organized into a compact bowing line segment across northern NC over the past 60-90 minutes. TRDU velocity imagery shows a consolidating outflow boundary associated with this line as well as severe winds at about 2-3 kft ARL, and GOES IR imagery shows rapid intensification via cooling cloud-top temperatures. This band will likely propagate to the east/northeast along a diffuse outflow boundary draped from eastern VA into northern NC. Ahead of the outflow, temperatures in the upper 80s and low 90s are supporting a regional buoyancy maximum (around 2000 J/kg MLCAPE) that, when coupled with 30-35 knots of effective bulk shear, should promote further intensification over the next couple of hours. Consequently, the severe wind threat should increase downstream along the VA/NC border. It remains unclear how far south the outflow will propagate as this intensification occurs, but watch issuance is probable if the band remains south of WW 442. ..Moore/Smith.. 06/19/2025 ...Please see www.spc.noaa.gov for graphic product...

WW 441 SEVERE TSTM CT MA NJ NY PA VT CW 191725Z - 200100Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 441 NWS Storm Prediction Center Norman OK 125 PM EDT Thu Jun 19 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Connecticut Western and Central Massachusetts Northern New Jersey Eastern New York Northeast Pennsylvania Vermont Coastal Waters * Effective this Thursday afternoon and evening from 125 PM until 900 PM EDT. * Primary threats include... Scattered damaging wind gusts to 60 mph likely Isolated large hail events to 1 inch in diameter possible SUMMARY...Thunderstorms will intensify this afternoon in a very moist and unstable air mass. The strongest cells will pose a risk of damaging wind gusts and hail. The severe thunderstorm watch area is approximately along and 60 statute miles east and west of a line from 40 miles northwest of Newport VT to 60 miles southeast of Wilkesbarre PA. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU1). PRECAUTIONARY/PREPAREDNESS ACTIONS...
