WW 401 SEVERE TSTM AR MS TN 092100Z - 100300Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 401 NWS Storm Prediction Center Norman OK 400 PM CDT Sun Jun 9 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Arkansas Northern Mississippi Far Southwest Tennessee * Effective this Sunday afternoon and evening from 400 PM until 1000 PM CDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2 inches in diameter possible Scattered damaging wind gusts to 70 mph possible SUMMARY...Thunderstorms should continue to develop and intensify late this afternoon and early evening while spreading slowly east-southeastward. Damaging winds of 55-70 mph may occur with any clusters, while severe hail of 1-2 inches in diameter appears possible with any discrete cells that can be maintained. The severe thunderstorm watch area is approximately along and 65 statute miles north and south of a line from 15 miles west of Russellville AR to 10 miles north northeast of Columbus MS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU1). 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. && AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 30030. ...Gleason Read more

MD 1223 CONCERNING SEVERE THUNDERSTORM WATCH 401...402... FOR PORTIONS OF NORTHERN AL...NORTHERN MS...AND SOUTHEASTERN AR
Mesoscale Discussion 1223 NWS Storm Prediction Center Norman OK 0719 PM CDT Sun Jun 09 2024 Areas affected...Portions of northern AL...northern MS...and southeastern AR Concerning...Severe Thunderstorm Watch 401...402... Valid 100019Z - 100145Z The severe weather threat for Severe Thunderstorm Watch 401, 402 continues. SUMMARY...The risk of isolated large hail and locally damaging gusts continues across parts of Severe Thunderstorm Watches 401 and 402. DISCUSSION...Isolated to widely scattered thunderstorms are ongoing from parts of southeastern AR eastward into northern AL -- generally focused along a sagging frontal boundary. While a warm/moist boundary layer and around 30-35 kt of unidirectional westerly deep-layer shear (per regional VWP) continue to support organized/transient supercell structures and small clusters, there has been a tendency for storms to be undercut by the southward-sagging boundary and outflow -- given the westerly storm motions and shear. This suggests that isolated large hail (up to 1.5 inches) will be the primary threat with any organized/sustained storms, though locally damaging gusts are also possible. ..Weinman.. 06/10/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1222 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF SOUTHWESTERN NC...NORTHWESTERN SC...AND FAR NORTHEAST GA
Mesoscale Discussion 1222 NWS Storm Prediction Center Norman OK 0649 PM CDT Sun Jun 09 2024 Areas affected...Portions of southwestern NC...northwestern SC...and far northeast GA Concerning...Severe potential...Watch unlikely Valid 092349Z - 100145Z Probability of Watch Issuance...20 percent SUMMARY...Locally damaging gusts and marginally severe hail are possible through around 02Z. A watch is not currently expected. DISCUSSION...A cluster of storms is evolving along the leading edge of antecedent outflow over western NC as of 2340Z, though organization has been limited thus far. As these storms continue east-southeastward through around 02Z, there is some potential for the development of a loosely organized cluster (and perhaps transient supercell structures), given a warm/moist pre-convective boundary layer and around 40-50 kt of unidirectional effective shear. However, poor midlevel lapse rates (contributing to a weak/skinny buoyancy profile), limited large-scale ascent, and time-of-day may tend to limit overall intensity/organization of storms. Nevertheless, locally damaging gusts (45-60 mph) and marginally severe hail (to near 1 inch) cannot be ruled out. Additional strong/loosely organized cellular development is also possible trailing southwestward into far northeastern GA, with a localized risk for strong gusts and marginally severe hail. Currently, the severe threat appears too localized and marginal for a watch, though convective trends will be monitored. ..Weinman/Bunting.. 06/09/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1221 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTHEAST OR INTO SOUTHWEST ID AND EXTREME NORTHERN NV
Mesoscale Discussion 1221 NWS Storm Prediction Center Norman OK 0628 PM CDT Sun Jun 09 2024 Areas affected...Southeast OR into southwest ID and extreme northern NV Concerning...Severe potential...Watch unlikely Valid 092328Z - 100130Z Probability of Watch Issuance...20 percent SUMMARY...Isolated hail and severe gusts are possible into early evening. DISCUSSION...Scattered thunderstorms are ongoing across southeast OR and vicinity, in advance of a shortwave trough moving across the Pacific Northwest. MLCAPE of up to 500 J/kg and moderate deep-layer shear are supporting occasionally organized storm structures, with a couple of stronger cells noted across Malheur County, Oregon. Those cells will eventually encounter stronger MLCINH to the northeast, but isolated hail and severe gusts will remain possible in the short term. Other less-organized convection is ongoing farther west into south-central OR, and also moving out of far northern NV. A stronger cell or two could develop across those areas as well, but even the ongoing less-organized convection could pose a threat of isolated strong to severe gusts, especially where the environment remains rather warm and well mixed. ..Dean/Bunting.. 06/09/2024 ...Please see www.spc.noaa.gov for graphic product...

Scattered strong/severe thunderstorms are expected this evening across the Mid South, while gusty winds and some hail threat remain possible with convection arcing across the High Plains into the northern inter mountain region. ...01z Update... Synoptic front/reinforced convective outflow, from early day MCS, has settled across the mid South region, arcing from northern GA-northern AL-northern MS-southern AR. Scattered robust thunderstorms have developed along/behind this wind shift and are propagating southeast within deeper mean northwesterly flow. Surface front will continue to advance south this evening and this activity should gradually sag south with the boundary. Gusty winds along with some hail threat will be noted with this activity. Elsewhere, seasonally weak mid-level flow extends around the northern periphery of the Rockies upper ridge. Strong boundary-layer heating across the northern interior Rockies region has contributed to steep lapse rates/buoyancy for scattered robust storms, especially from southeast OR into eastern ID. This activity should gradually weaken over the next few hours with loss of daytime heating. ..Darrow.. 06/10/2024 Read more
