SEVERE STORMS ARE UNLIKELY ON TUESDAY.
..SYNOPSIS
A DEEP UPPER TROUGH WILL QUICKLY MOVE OUT OF EASTERN QUEBEC AND NEW

SOUTHEAST ACROSS ONTARIO AND UPPER GREAT LAKES. THIS NORTHWEST FLOW
REGIME WILL GENERALLY MAINTAIN HIGH PRESSURE OVER MUCH OF THE
CENTRAL AND EASTERN CONUS, WITH NORTHEAST SURFACE WINDS NEAR THE
GULF AND ATLANTIC COASTS. AS SUCH, AVAILABLE MOISTURE AND
INSTABILITY WILL REMAIN LARGELY OFFSHORE, EXCEPT OVER FL WHERE
AFTERNOON THUNDERSTORMS ARE POSSIBLE. SEVERE STORMS ARE UNLIKELY DUE
TO THE WEAK SHEAR/LAPSE RATE ENVIRONMENT.
ELSEWHERE, SCATTERED SHOWERS AND THUNDERSTORMS MAY AFFECT THE
EASTERN GREAT BASIN INTO WESTERN CO, AS A WEAK MIDLEVEL WAVE MOVES
OVER THE AREA WITH COOL TEMPERATURES ALOFT. SEVERE STORMS ARE
UNLIKELY GIVEN WEAK INSTABILITY AND SHEAR.
