..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE STORMS ARE NOT EXPECTED ON THURSDAY.
..SYNOPSIS
AN UPPER LOW WILL MOVE EAST OUT OF JAMES BAY AND INTO QUEBEC ON
THURSDAY, WITH A BROAD UPPER TROUGH FROM THE GREAT LAKES INTO THE
NORTHEAST. A LEADING MIDLEVEL SPEED MAX IS FORECAST TO MOVE ACROSS
SOUTHERN NEW ENGLAND DURING THE DAY, WITH COLD TEMPERATURES ALOFT TO
THE NORTH. THIS MAY FAVOR ISOLATED LOW-TOPPED THUNDERSTORMS FROM THE
UPPER HUDSON VALLEY INTO MAINE AS SURFACE HEATING OCCURS AND A WIND
SHIFT/TROUGH SWEEPS ACROSS THE REGION. VERY SMALL HAIL CANNOT BE
RULED OUT WITH 500 MB TEMPERATURES NEAR -25 C.
TO THE SOUTH, STRONG LOW-LEVEL EASTERLIES WILL DEVELOP OVER THE
NORTHERN GULF OF AMERICA AS THE TROPICAL CYCLONE STRENGTHENS OVER
THE CENTRAL GULF, POSSIBLY INTO A HURRICANE BY THURSDAY EVENING PER
NHC. THIS FLOW REGIME WILL MAINTAIN 70S F DEWPOINTS OVER FL, WITH
SCATTERED AFTERNOON THUNDERSTORMS POSSIBLE. SEVERE STORMS ARE NOT
EXPECTED DUE TO WEAK SHEAR AND POOR LAPSE RATES.
TO THE WEST, COOL MIDLEVEL TEMPERATURES TO -12 C WILL EXIST OVER THE
GREAT BASIN, WITH SPARSE WEAK THUNDERSTORMS OVER PARTS OF THE FOUR
CORNERS STATES DURING THE AFTERNOON.
ELSEWHERE, A FEW THUNDERSTORMS MAY OCCUR FROM EASTERN NE INTO IA
LATE IN THE DAY AND OVERNIGHT AS SOUTHWESTERLY 850 MB WINDS INCREASE
TO 30 KT, WITH SUFFICIENT ELEVATED INSTABILITY PRESENT IN THE WARM
ADVECTION/HEIGHT RISE REGIME.
