SPC Jun 24, 2022 0100 UTC Day 1 Convective Outlook

 SPC AC 240116 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0816 PM CDT Thu Jun 23 2022 Valid 240100Z - 241200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF SOUTH DAKOTA AND MINNESOTA...AND PORTIONS OF KANSAS AND NEBRASKA... ...SUMMARY... Scattered severe thunderstorms will continue this evening across ongoing risk areas, particularly over parts of the central Great Plains and central portions of Minnesota to South Dakota. ...South Dakota to Minnesota vicinity... Isolated thunderstorms are ongoing at this time from northeastern Minnesota southwestward into northern South Dakota. The storms are occurring within a moderately unstable airmass in the vicinity of a surface boundary extending northeastward from a low analyzed over central South Dakota. A modest/nocturnal increase in low-level southerly flow is forecast across this area, which should sustain storms -- and local severe risk -- for several more hours, before an eventual/gradual decrease in storm coverage expected overnight. ...North-central Kansas vicinity... Storms continue across portions of northern Kansas at this time, near a warm-frontal zone draped across this area. While moderate instability will allow storms to persist over the next few hours, a well-developed supercell which earlier crossed Lincoln/northern Ellsworth counties and produced a couple of tornadoes has since diminished. Still, isolated severe storms -- primarily capable of producing large hail and locally strong wind gusts, will remain possible over the next few hours. ...Portions of central and eastern Montana... Widely scattered thunderstorms are ongoing across parts of central and eastern Montana, near a surface cold front slowly crossing the area. Weak/high-based instability remains in the vicinity of the boundary, but loss of daytime heating should result in gradual decrease in convective coverage/intensity beginning over the next couple of hours. Until then, evaporatively aided surface wind gusts near severe levels will remain possible. ...Eastern Nevada into Utah and southwestern Wyoming... Isolated/high-based thunderstorms continue at this hour near and just ahead of the upper low now over western portions of Nevada per the latest water-vapor loop. While gusty winds remain possible with a couple of the strongest storms -- particularly over northeastern Utah and into southwestern Wyoming where some convective clustering/upscale growth has occurred, convection will begin diminishing in coverage and intensity a bit later this evening in tandem with the loss of daytime heating. ..Goss.. 06/24/2022 CLICK TO GET WUUS01 PTSDY1 PRODUCT NOTE: THE NEXT DAY 1 OUTLOOK IS SCHEDULED BY 0600Z
