VALID 141200Z - 151200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS NORTHERN
NEW ENGLAND...
..SUMMARY
SEVERE THUNDERSTORMS WILL BE POSSIBLE DURING THE AFTERNOON AND
EVENING ACROSS PORTIONS OF NEW ENGLAND ON TUESDAY. ADDITIONAL
STRONG-TO-SEVERE THUNDERSTORMS WILL BE POSSIBLE ACROSS PARTS OF
WESTERN AND CENTRAL MONTANA.
..NEW ENGLAND
A STRONG SHORTWAVE TROUGH IS EXPECTED TO MOVE INTO THE REGION DURING
THE EVENING. THE STRONGEST FORCING FOR ASCENT WILL LIKELY ARRIVE
AFTER DARK. STILL, LOW-LEVEL MOISTENING WILL PROMOTE MODERATE TO
STRONG BUOYANCY EVEN INTO THE EVENING (1500-2500 J/KG MUCAPE). 50-60
KT OF 0-6 KM SHEAR WILL PROMOTE ORGANIZED CONVECTION CAPABLE OF
LARGE HAIL AND SEVERE WIND GUSTS. A CONDITIONAL TORNADO THREAT WILL
ALSO EXIST WITH ANY SUPERCELL STRUCTURES THAT CAN REMAIN SURFACE
BASED.
..MONTANA
MODERATE TO STRONG MID-LEVEL CYCLONIC FLOW WILL CONTINUE WITHIN THE
NORTHERN ROCKIES. AN INCREASE IN LOW/MID-LEVEL MOISTURE IS EXPECTED
AS COMPARED TO PREVIOUS DAYS. A SHORTWAVE TROUGH COUPLED WITH AT
LEAST MODEST HEATING WITHIN THE HIGHER TERRAIN WILL PROMOTE WIDELY
SCATTERED TO SCATTERED STORMS. WITH AN INCREASE IN CLOUD COVER
EXPECTED, IT IS NOT CLEAR WHETHER STORMS WILL BE SURFACE BASED.
SEVERE WIND GUSTS AND MARGINALLY SEVERE HAIL ARE POSSIBLE WITH THE
STRONGEST STORMS.
