WW 357 SEVERE TSTM LA MS 310310Z - 310700Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 357 NWS Storm Prediction Center Norman OK 1010 PM CDT Thu May 30 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Eastern Louisiana Southwest Mississippi * Effective this Thursday night and Friday morning from 1010 PM until 200 AM CDT. * Primary threats include... Isolated damaging wind gusts to 70 mph possible SUMMARY...A line of strong/severe storms capable of damaging wind gusts will track eastward across the watch area for the next few hours. The severe thunderstorm watch area is approximately along and 40 statute miles east and west of a line from 35 miles north of Natchez MS to 75 miles south of Natchez MS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU7). 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 354...WW 356... AVIATION...A few severe thunderstorms with hail surface and aloft to 1.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 27035. ...Hart Read more

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1253 AM CDT Fri May 31 2024 Valid 011200Z - 021200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE CENTRAL AND SOUTHERN HIGH PLAINS... ...SUMMARY... Scattered strong storms, including a few supercells, may develop across the central and southern High Plains Saturday afternoon, before evolving into organizing clusters while spreading into the adjacent Great Plains through Saturday evening. These may pose a risk for severe wind, hail and perhaps a couple of brief tornadoes. ...Synopsis... Upper ridging is forecast to extend from the TN Valley into southwest Quebec early Saturday morning before then gradually shifting eastward towards the East Coast and deamplifying. A pair of shortwave troughs are expected to be over the central CONUS in the wake of this ridging, with the southernmost shortwave likely augmented by convection over the southern Plains on Friday. This southern shortwave trough is forecast to progress eastward/northeastward across the Mid-South and into the TN Valley. Some phasing between this southern shortwave trough and the more substantial northern-stream shortwave trough as it moves across the Canadian Prairie Provinces/northern Plains into Quebec/Upper Midwest. Broad surface troughing will precede both of these waves, with a modest surface low moving from MO across the OH Valley. Zonal flow is expected across much of the Plains in the wake of these shortwave troughs, with another shortwave trough forecast to move from the West Coast into the Intermountain West. A low-amplitude shortwave trough is also expected to move across northern Mexico and into West Texas Saturday afternoon/evening. ...Central/Southern High Plains... A moist airmass will remain over the central and southern Plains, with advection into the central/southern High Plains expected as lee troughing sharpens throughout the day. Strong heating is anticipated, which will work in tandem with increasing low-level moisture to destabilize the airmass. As a result, afternoon thunderstorm development is possible along the length of the lee trough, with the highest coverage expected over eastern CO and far west TX. High-based, outflow-dominant storm structures are anticipated, with at least some chance for organization into one or more convective lines. This appears most likely across eastern CO into western KS, but could occur farther south as well. Large hail is possible with the initial more cellular development, but a relatively quick transition to damaging gusts is anticipated given the expected outflow-dominant structures. Veered low-level flow should limit the tornado potential across much of the region except in northeast CO and southeast NM/TX Trans-Pecos where the greatest potential for southeasterly surface winds exists. ...MS Valley into Southeast TX and the Southeast States... Thunderstorms will likely be ongoing early Saturday morning over the Mid to Lower MS Valley, ahead of the convectively augmented shortwave trough expected to be progressing through the region. This shortwave is forecast to progress gradually northeastward into the Lower OH Valley while additional thunderstorms develop along the southeastward/eastward-progressing outflow from southeast TX into AL and MS. Moist but weakly sheared airmass could support multicell structures with updrafts occasionally strong enough to produce water-loaded downbursts. ..Mosier.. 05/31/2024 Read more

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1253 AM CDT Fri May 31 2024 Valid 011200Z - 021200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE CENTRAL AND SOUTHERN HIGH PLAINS... ...SUMMARY... Scattered strong storms, including a few supercells, may develop across the central and southern High Plains Saturday afternoon, before evolving into organizing clusters while spreading into the adjacent Great Plains through Saturday evening. These may pose a risk for severe wind, hail and perhaps a couple of brief tornadoes. ...Synopsis... Upper ridging is forecast to extend from the TN Valley into southwest Quebec early Saturday morning before then gradually shifting eastward towards the East Coast and deamplifying. A pair of shortwave troughs are expected to be over the central CONUS in the wake of this ridging, with the southernmost shortwave likely augmented by convection over the southern Plains on Friday. This southern shortwave trough is forecast to progress eastward/northeastward across the Mid-South and into the TN Valley. Some phasing between this southern shortwave trough and the more substantial northern-stream shortwave trough as it moves across the Canadian Prairie Provinces/northern Plains into Quebec/Upper Midwest. Broad surface troughing will precede both of these waves, with a modest surface low moving from MO across the OH Valley. Zonal flow is expected across much of the Plains in the wake of these shortwave troughs, with another shortwave trough forecast to move from the West Coast into the Intermountain West. A low-amplitude shortwave trough is also expected to move across northern Mexico and into West Texas Saturday afternoon/evening. ...Central/Southern High Plains... A moist airmass will remain over the central and southern Plains, with advection into the central/southern High Plains expected as lee troughing sharpens throughout the day. Strong heating is anticipated, which will work in tandem with increasing low-level moisture to destabilize the airmass. As a result, afternoon thunderstorm development is possible along the length of the lee trough, with the highest coverage expected over eastern CO and far west TX. High-based, outflow-dominant storm structures are anticipated, with at least some chance for organization into one or more convective lines. This appears most likely across eastern CO into western KS, but could occur farther south as well. Large hail is possible with the initial more cellular development, but a relatively quick transition to damaging gusts is anticipated given the expected outflow-dominant structures. Veered low-level flow should limit the tornado potential across much of the region except in northeast CO and southeast NM/TX Trans-Pecos where the greatest potential for southeasterly surface winds exists. ...MS Valley into Southeast TX and the Southeast States... Thunderstorms will likely be ongoing early Saturday morning over the Mid to Lower MS Valley, ahead of the convectively augmented shortwave trough expected to be progressing through the region. This shortwave is forecast to progress gradually northeastward into the Lower OH Valley while additional thunderstorms develop along the southeastward/eastward-progressing outflow from southeast TX into AL and MS. Moist but weakly sheared airmass could support multicell structures with updrafts occasionally strong enough to produce water-loaded downbursts. ..Mosier.. 05/31/2024 Read more
