000 ACUS01 KWNS 060521 SWODY1 SPC AC 060519 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1119 PM CST Fri Mar 05 2021 Valid 061200Z - 071200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected. ...Northern Rockies... Strong mid-level height falls will spread across the northern Rockies during the day1 period ahead of a sharp short-wave trough that will progress into western MT/WY by 07/00z. While moisture will prove sparse across this region (PW on the order of .30 inches), very steep lapse rates and cool profiles suggest weak convection should develop ahead of a cold front between 20z-07/00z. Forecast soundings suggest there may be enough buoyancy for a few lightning flashes with the strongest updrafts. ...FL... Primary surface wave should track across the eastern Gulf Basin into the FL Straits by early evening in response to a digging short-wave trough. This evolution suggests the greatest risk for thunderstorms will focus well west of the Peninsula where buoyancy/low-level convergence will be maximized. Even so, there appears to be a low risk for a few thunderstorms in association with a southward-moving cold front across the central/southern Peninsula. Generally weak convergence over land should limit convective coverage. ..Darrow/Moore.. 03/06/2021 $$
