Scattered damaging winds likely with isolated significant gusts to 75 mph possible Scattered large hail likely with isolated very large hail events to 2.5 inches in diameter possible SUMMARY...Multiple areas of thunderstorm development are possible along and south of the Kansas/Oklahoma border through late evening, in a storm environment favoring organized clusters and supercells. The more intense storms will be capable of producing very large hail up to 2.5 inches in diameter, as well as severe outflow winds up to 75 mph. The severe thunderstorm watch area is approximately along and 35 statute miles north and south of a line from 40 miles west southwest of Alva OK to 30 miles south southeast of Monett MO. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). 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 627... AVIATION...A few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 600. Mean storm motion vector 30025. ...Thompson Read more

WW 629 SEVERE TSTM AR 170200Z - 170700Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 629 NWS Storm Prediction Center Norman OK 900 PM CDT Fri Aug 16 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of West-central to north-central Arkansas * Effective this Friday night and Saturday morning from 900 PM until 200 AM CDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 75 mph possible Isolated very large hail events to 2 inches in diameter possible SUMMARY...A complex of severe thunderstorms -- with a history of severe as recently as a 56-kt gust at NW AR Regional (XNA) at 141Z -- is expected to pose a continuing severe-wind and hail threat southeastward into more of AR this evening. Some expansion or shift in motion toward southward also is possible. The severe thunderstorm watch area is approximately along and 40 statute miles north and south of a line from 10 miles south of Fort Smith AR to 55 miles northeast of Russellville AR. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU9). 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 628... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches.

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0751 PM CDT Fri Aug 16 2024 Valid 170100Z - 171200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHERN PLAINS/SOUTHEAST KANSAS INTO NORTHERN ARKANSAS... ...SUMMARY... Scattered severe thunderstorms remain possible this evening across portions of the southern Plains/southeast Kansas into northwest Arkansas. Damaging gusts and hail are the primary threats. ...01z Update... Low-amplitude short-wave trough is currently evident in satellite imagery, extending from southeast KS-northeast TX Panhandle. This feature is digging southeast within mean northwesterly flow along the back side of the Great Lakes/OH Valley trough. Synoptic front that advanced into this region arcs across MO-southern KS-northern TX Panhandle. This boundary is serving as a focus for scattered robust convection, mostly concentrated across southeast KS/extreme northeast OK along the northern fringe of a most buoyant airmass. Surface temperatures remain in the 90s to near 100F south of the boundary across much of OK into the TX south Plains. 00z sounding from OUN exhibits MLCAPE on the order of 3000 J/kg with 30kt 0-6km bulk shear. Latest VWP data depicts 1km flow around 15kt across northeast OK, but models suggest LLJ will increase over the next several hours into northeast OK where values may exceed 30kt. This will favor a southeast-moving complex of storms into northern AR later this evening. Damaging gusts and hail remain the primary threats. ..Darrow.. 08/17/2024 Read more
