MD 1443 CONCERNING SEVERE THUNDERSTORM WATCH 472... FOR FAR EASTERN CONNECTICUT/RHODE ISLAND/CENTRAL AND EASTERN MASSACHUSETTS
Mesoscale Discussion 1443 NWS Storm Prediction Center Norman OK 1012 PM CDT Wed Jun 26 2024 Areas affected...far eastern Connecticut/Rhode Island/central and eastern Massachusetts Concerning...Severe Thunderstorm Watch 472... Valid 270312Z - 270415Z The severe weather threat for Severe Thunderstorm Watch 472 continues. SUMMARY...A band of strong/severe storms continues moving eastward across southern New England, where locally damaging wind gusts remain possible over the next couple of hours. DISCUSSION...Latest radar loop shows a north-south band of strong/severe storms moving eastward at around 40 kt in the vicinity of the Connecticut/Rhode Island border. The storms have a history of producing strong/severe wind gusts, including a 67 kt gust at Hartford/Bradley Airport (KBDL) in the past hour. While instability is gradually diminishing nocturnally, and capping correspondingly increasing, storms will likely maintain intensity given the degree of organization. With that said, hints exist in KBOX radar data that outflow is beginning to outpace the main band of storms. This -- and the ongoing nocturnal boundary-layer cooling -- suggests that storms are becoming slightly elevated with time. Still, locally severe/damaging gusts remain possible over the next 1 to 2 hours. ..Goss.. 06/27/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...BOX...

MD 1441 CONCERNING SEVERE THUNDERSTORM WATCH 470... FOR PORTIONS OF NORTH TEXAS
Mesoscale Discussion 1441 NWS Storm Prediction Center Norman OK 0827 PM CDT Wed Jun 26 2024 Areas affected...Portions of North Texas Concerning...Severe Thunderstorm Watch 470... Valid 270127Z - 270300Z The severe weather threat for Severe Thunderstorm Watch 470 continues. SUMMARY...Large hail and severe winds remain possible with a supercell in North Texas. Southern extent of the threat is not clear. Watch extensions will need to be considered if trends warrant. DISCUSSION...A supercell near Denison/Sherman has generally been moving south-southwestward roughly along an outflow boundary. This storm will likely continue into the mid evening. So far, 1 inch hail has been reported with this storm. MLCIN has been increasing to the south over the last hour. However, with an established supercell, it will take time to have a negative impact on the storm. The outflow boundary drapes southward trough western portions of the Metroplex. The observed 00Z FWD showed modest MLCIN along with steep mid-level lapse rates and 34 kts of effective shear. It is not clear whether this storm will persist far enough to impact DFW proper, but it is possible. Trends will need to be monitored for possible watch extensions farther south. ..Wendt.. 06/27/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...FWD...OUN...

Scattered damaging wind gusts to 60 mph possible SUMMARY...A broken linear cluster of strong to severe thunderstorms will likely continue east across northern Virginia and adjacent portions of Maryland through the late evening. Strong to locally severe gusts (50-60 mph) capable of wind damage will be possible with the stronger thunderstorms and outflow surges as this activity moves east. The severe thunderstorm watch area is approximately along and 45 statute miles north and south of a line from 35 miles south of Martinsburg WV to 45 miles east of Baltimore MD.

Mesoscale Discussion 1438 NWS Storm Prediction Center Norman OK 0751 PM CDT Wed Jun 26 2024 Areas affected...Southern Idaho into southwest Montana Concerning...Severe Thunderstorm Watch 468... Valid 270051Z - 270245Z The severe weather threat for Severe Thunderstorm Watch 468 continues. SUMMARY...Storms will remain capable of severe winds and marginally severe hail into the evening. The environment becomes less favorable to the east and a weakening trend is expected as storms move into southwest Montana. DISCUSSION...Scattered convection continues across parts of southern Idaho and will eventually progress into southwest Montana. With the continued approach of the upper-level trough this evening, some additional development remains possible in western Idaho. The most intense storms will continue to pose a risk for severe winds as well as marginally severe hail. The hail threat should generally be modulated by somewhat limited buoyancy. With temperatures cooler and the airmass drier into southwest Montana, storms are expected to gradually weaken with eastward extent. ..Wendt.. 06/27/2024 ...Please see www.spc.noaa.gov for graphic product...

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 470 NWS Storm Prediction Center Norman OK 715 PM CDT Wed Jun 26 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southern Oklahoma North Texas * Effective this Wednesday evening from 715 PM until 1100 PM CDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 75 mph possible Scattered large hail and isolated very large hail events to 2 inches in diameter possible SUMMARY...Isolated to scattered severe thunderstorms are possible this evening near the Texas-Oklahoma Red River Valley. The stronger thunderstorms may yield a large to very large hail threat (1 to 2 inches in diameter) and severe gusts 60-75 mph. This thunderstorm activity will likely wane by late evening into the early overnight. The severe thunderstorm watch area is approximately along and 40 statute miles north and south of a line from 45 miles west southwest of Altus OK to 30 miles east southeast of Durant OK. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU0). PRECAUTIONARY/PREPAREDNESS ACTIONS...

Mesoscale Discussion 1439 NWS Storm Prediction Center Norman OK 0753 PM CDT Wed Jun 26 2024 Areas affected...southeastern New York and southern New England Concerning...Severe Thunderstorm Watch 469... Valid 270053Z - 270230Z The severe weather threat for Severe Thunderstorm Watch 469 continues. SUMMARY...Risk for damaging winds continues -- particularly across northern parts of WW 469. At least some risk should eventually spread into Rhode Island parts of Massachusetts, possibly requiring new WW consideration in the next hour or so. DISCUSSION...Latest radar loop shows a band of strong to severe storms moving east-northeastward into/across southeastern New York including the New York City area at this time. Locally strong/damaging wind gusts remain the primary risk with these storms, which should continue over the next few hours -- moving across Connecticut and Long Island. With the instability axis extending eastward into Rhode Island and portions of Massachusetts near and south of the ongoing/persistent, west-to-east band of storms, at least some risk may extend east of the existing watch in the next couple of hours. This could warrant new WW consideration. ..Goss.. 06/27/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...BOX...OKX...ALY...

Mesoscale Discussion 1440 NWS Storm Prediction Center Norman OK 0808 PM CDT Wed Jun 26 2024 Areas affected...Portions of southwestern Pennsylvania and vicinity Concerning...Severe Thunderstorm Watch 467... Valid 270108Z - 270215Z The severe weather threat for Severe Thunderstorm Watch 467 continues. SUMMARY...Local severe risk continues across portions of southwestern Pennsylvania and a small portion of adjacent West Virginia and Maryland. New/downstream WW not anticipated. DISCUSSION...Latest radar loop shows a band of storms moving across the mountains of southwestern Pennsylvania, and southwestward into northern West Virginia. The strongest storms are ongoing near an MCV crossing the Indiana County vicinity, where transient rotation and possibly a weak/brief tornado touchdown may have occurred in the past hour. Local risk for an additional/brief tornado and/or strong wind gusts will continue across northeastern portions of WW 467. Some instability extends northward into south-central Pennsylvania, east of WW 467, per RAP-based objective analysis. This may allow local/limited severe risk to persist over the next couple of hours, east of the watch. However, it appears that risk will remain isolated -- likely negating the need for new WW issuance. ..Goss.. 06/27/2024 ...Please see www.spc.noaa.gov for graphic product...
