..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE STORMS ARE NOT EXPECTED THROUGH WEDNESDAY NIGHT.
..SYNOPSIS
TO THE NORTH OF A STRONG MIDLEVEL HIGH OVER THE SOUTHERN ROCKIES, A
SHORTWAVE TROUGH WILL MOVE INLAND OVER WA DURING THE DAY AND
PROGRESS QUICKLY EASTWARD TO MN/WESTERN ON BY EARLY THURSDAY.
CYCLOGENESIS IN ADVANCE OF THIS MIDLEVEL TROUGH WILL HELP DRAW A
MODIFYING AIR MASS NORTH AND NORTHEASTWARD FROM THE SOUTHERN PLAINS
TO THE MID MS VALLEY. OVERNIGHT WEDNESDAY INTO EARLY THURSDAY,
MOISTENING NEAR/ABOVE THE SURFACE COULD BE SUFFICIENT FOR ELEVATED
CONVECTION IN A WARM ADVECTION ZONE ACROSS PARTS OF THE MIDWEST.
ELSEWHERE, A FEW THUNDERSTORMS WILL BE POSSIBLE ACROSS FL ALONG A
DISSIPATING FRONT, LOCAL SEA BREEZE CIRCULATIONS AND ANY LINGERING
CONVECTIVE OUTFLOW OR DIFFERENTIAL HEATING ZONES. ISOLATED
LIGHTNING FLASHES WILL ALSO BE POSSIBLE WITH LOW-TOPPED CONVECTION
DURING THE DAY IN THE POST-FRONTAL ENVIRONMENT ALONG AND WEST OF THE
CASCADES IN WA.
