SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0754 PM CDT Wed May 25 2022 Valid 260100Z - 261200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM THE LOWER MISSISSIPPI VALLEY TO THE SOUTHERN GREAT LAKES... ...SUMMARY... Isolated strong to severe thunderstorms remain possible, primarily across the central Gulf Coast states tonight. ...01z Update... Center of upper low is currently located over northern OK. This feature will move slowly northeast tonight as stronger flow advances downstream into the lower MS/western TN Valley region. While bands of strong/severe convection have developed well ahead of this feature, primary surface front may become more convectively active later this evening across AR/LA. Both LCH and LZK exhibited weak/minimal inhibition in their 00Z soundings and isolated thunderstorms are now forming along the boundary across AR. As weak mid-level height falls spread across this region there appears to be some chance for renewed convection along the front later this evening. Earlier corridor of strong/severe thunderstorms across MS/AL has shifted a bit downstream and a few robust storms may linger across this region with some attendant threat for locally strong winds or perhaps a brief tornado. Elsewhere, scattered showers/thunderstorms persist from the TN Valley into the southern Great Lakes region. Overall trends have been down with this activity but modest shear and ample buoyancy will likely continue to support at least a few robust updrafts this evening. Primary risk appears to be locally gusty winds. ..Darrow.. 05/26/2022Read more
