Scattered damaging wind gusts to 70 mph possible Isolated large hail events to 1 inch in diameter possible A tornado or two possible SUMMARY...Scattered damaging winds up to 55-70 mph may occur as thunderstorms spread eastward this afternoon and evening. The severe thunderstorm watch area is approximately along and 30 statute miles north and south of a line from 80 miles west of Elkins WV to 20 miles east of Martinsburg WV. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU3). 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 482... AVIATION...A few severe thunderstorms with hail surface and aloft to 1 inch.

MD 1484 CONCERNING SEVERE THUNDERSTORM WATCH 487... FOR PORTIONS OF THE TEXAS PANHANDLE INTO NORTHWESTERN OKLAHOMA
Mesoscale Discussion 1484 NWS Storm Prediction Center Norman OK 0700 PM CDT Sat Jun 29 2024 Areas affected...portions of the Texas Panhandle into northwestern Oklahoma Concerning...Severe Thunderstorm Watch 487... Valid 300000Z - 300130Z The severe weather threat for Severe Thunderstorm Watch 487 continues. SUMMARY...The severe threat continues across Severe Thunderstorm Watch 487. Severe gusts are the main threat, though an instance of large hail cannot be ruled out. DISCUSSION...Several pulse-single cells, multicells, and transient supercells have formed along the slowly southward-sagging surface cold front over the past couple of hours. At least one measured severe gust has been reported in northern OK, with regional and MRMS mosaic radar data showing severe hail and wind potential with the storms over the TX Panhandle. The ambient atmosphere can still be characterized by strong to locally extreme instability, so any of the stronger storms progressing within a pristine airmass may still produce severe wind and hail over the next few hours. ..Squitieri.. 06/30/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0800 PM CDT Sat Jun 29 2024 Valid 300100Z - 301200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THROUGH LATE EVENING FROM NORTHERN OK TO SOUTHERN MO...AND FROM WV INTO SOUTHEAST PA... ...SUMMARY... Isolated damaging gusts and large hail will be possible for a few more hours into early tonight from northern Oklahoma into southern Missouri, and across parts of the central Appalachians. ...01z... Main changes in this update will be to extend the SLGT risk westward across northern OK to reflect wind-damage potential with storms along a surface wind shift through late evening, and to remove most of the SLGT in the WV/OH/PA/NY area where diurnal stabilization and prior storms should limit the threat overnight. The threat appears lower overnight across the southern High Plains tonight as the low levels slowly stabilize in an upslope regime. Storm clusters are still expected, though the hail/wind threat should remain marginal. ..Thompson.. 06/30/2024 Read more

MD 1482 CONCERNING SEVERE THUNDERSTORM WATCH 483... FOR NORTHERN WV AND THE WESTERN MD PANHANDLE
Mesoscale Discussion 1482 NWS Storm Prediction Center Norman OK 0630 PM CDT Sat Jun 29 2024 Areas affected...northern WV and the western MD Panhandle Concerning...Severe Thunderstorm Watch 483... Valid 292330Z - 300100Z The severe weather threat for Severe Thunderstorm Watch 483 continues. SUMMARY...A marginal and fairly isolated severe threat may persist through about dusk. Additional severe thunderstorm watch issuance beyond the 02Z expiration is unlikely. DISCUSSION...A lone robust updraft exists within WW 483 across north WV. This specific cell appeared to be a left-split amid a nearly unidirectional wind profile inferred between RLX/PBZ VWPs. This may have briefly produced marginally severe hail per MESH signatures, but appears to have peaked. In its wake, a stronger storm cluster over southwest OH has likewise appeared to have peaked in convective intensity. With weak low-level flow persisting to the south of both convective areas, the overall severe threat should continue on a diminishing trend, although storms should persist beyond dusk. ..Grams.. 06/29/2024 ...Please see www.spc.noaa.gov for graphic product...
