WW 638 SEVERE TSTM AL FL GA CW 182310Z - 190600Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 638 NWS Storm Prediction Center Norman OK 710 PM EDT Sun Aug 18 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southern Alabama Florida Panhandle Southern Georgia Coastal Waters * Effective this Sunday night and Monday morning from 710 PM until 200 AM EDT. * Primary threats include... Scattered damaging wind gusts to 65 mph possible SUMMARY...Clusters of storms capable of wind damage and possibly some hail will continue south-southeastward across the region this evening within a hot/moist environment. The severe thunderstorm watch area is approximately along and 55 statute miles north and south of a line from 50 miles northwest of Pensacola FL to 30 miles east southeast of Vidalia GA. 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 634...WW 635...WW 636...WW 637... AVIATION...A few severe thunderstorms with hail surface and aloft to 1 inch. Extreme turbulence and surface wind gusts to 55 knots. A few cumulonimbi with maximum tops to 550. Mean storm motion vector 31025. ...Guyer Read more

MD 1950 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF SOUTHEAST IDAHO INTO SOUTHWEST MONTANA
Mesoscale Discussion 1950 NWS Storm Prediction Center Norman OK 0606 PM CDT Sun Aug 18 2024 Areas affected...Portions of southeast Idaho into southwest Montana Concerning...Severe potential...Watch unlikely Valid 182306Z - 190130Z Probability of Watch Issuance...20 percent SUMMARY...Isolated severe wind gusts and severe hail are possible as thunderstorms track northeastward into this evening. A watch is not expected. DISCUSSION...Isolated to widely scattered thunderstorms are evolving across portions of southeast ID and southwest MT this afternoon -- along the eastern periphery of a large-scale trough off the Pacific Northwest coast. These storms are along the eastern periphery of a belt of 30-40 kt midlevel southwesterly flow, which is contributing to favorable deep-layer shear for some convective organization -- given sufficient (albeit weak) surface-based instability and steep deep-layer lapse rates. Initial cellular activity will pose a risk of isolated severe hail and locally severe downbursts. With time, some localized upscale growth is expected as storms track northeastward into this evening, with an increasing risk of embedded severe wind gusts (60-70 mph). Overall, the severe risk is expected to be too localized for a watch consideration. ..Weinman/Guyer.. 08/18/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1951 CONCERNING SEVERE THUNDERSTORM WATCH 637... FOR NORTHWEST ARKANSAS INTO EAST-CENTRAL MISSISSIPPI
Mesoscale Discussion 1951 NWS Storm Prediction Center Norman OK 0613 PM CDT Sun Aug 18 2024 Areas affected...Northwest Arkansas into east-central Mississippi Concerning...Severe Thunderstorm Watch 637... Valid 182313Z - 190115Z The severe weather threat for Severe Thunderstorm Watch 637 continues. SUMMARY...Damaging winds and isolated large hail will remain possible into the early evening. Storms in northwest and south-central Arkansas will pose the greatest risk of these hazards. DISCUSSION...Scattered storm development in central Arkansas has produced a cold pool that is pushing south and east. Storms, particularly along the southern edge where it is more unstable, continue to develop. Recently, Pine Bluff gusted to 44 kts as storms moved through. this activity will continue to pose a risk for damaging winds and isolated large hail as it progresses south/southeast. In Northwest Arkansas, additional storms are beginning to develop as a weakening MCV/cold pool moves into the strongly buoyant airmass. Wind gusts of 44-56 kts have already been observed with this activity. Isolated large hail may also occur within initially discrete updrafts. The airmass in west-central Arkansas has thus far not been affected by convection and this activity may tend to propagate into this area. ..Wendt.. 08/18/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0751 PM CDT Sun Aug 18 2024 Valid 190100Z - 191200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF THE MID-ATLANTIC INTO THE SOUTHEAST... ...SUMMARY... Clusters of severe thunderstorms with strong/damaging winds remain possible into tonight along an axis from eastern Kansas into Mississippi, then extending eastward into the Carolinas and Mid Atlantic region. A couple severe wind/hail producing storms may persist across the northern Rockies, with a couple of storms crossing the international border into North Dakota. ...Synopsis... An upper ridge persists across the central U.S. as a mid-level trough meanders toward the Atlantic from the eastern U.S. Scattered to numerous thunderstorms (some strong to occasionally severe) continue to percolate in intensity all along the periphery of both the upper trough and ridge, from the eastern Seaboard to the northern Rockies. Moderate to strong buoyancy should persist for at least a couple of hours past sunset, promoting continued severe wind/hail potential with the stronger storms. The primary changes to the outlook were to trim severe probabilities across portions of the Mid Atlantic, Southeast, and the central Rockies, where multiple rounds of thunderstorms have diluted buoyancy. Otherwise, Category 1/Marginal risk probabilities, driven by wind/hail, were added to parts of north-central ND, where a few southward-surging supercells may cross the international border with a severe threat before nocturnal cooling and associated MLCINH help weaken the storms. ..Squitieri.. 08/19/2024 Read more
