...STRONG COLD FRONT TO SPARK SHOWERS AND THUNDERSTORMS AND
POSSIBLE SEVERE WEATHER ACROSS PORTIONS OF THE NORTHEAST THROUGH
THIS EVENING...
...STRENGTHENING FRONTAL SYSTEM WILL BRING WIDESPREAD SHOWERS AND
THUNDERSTORMS FROM THE INTERMOUNTAIN WEST AND ROCKIES TO THE
PLAINS OVER THE NEXT COUPLE OF DAYS...
...DANGEROUS HEAT CONTINUES ACROSS THE SOUTH-CENTRAL U.S. THROUGH
MIDWEEK...
MOISTURE STREAMING NORTHWARD AHEAD OF A STRONG, WELL-DEFINED COLD
FRONT PUSHING ACROSS THE NORTHEAST WILL SET THE STAGE FOR
SCATTERED SHOWERS AND THUNDERSTORMS THIS AFTERNOON AND EVENING.
SOME OF THESE STORMS COULD BECOME STRONG TO SEVERE, WITH DAMAGING
WIND GUSTS THE PRIMARY THREAT. ONCE THE COLD FRONT CLEARS THE EAST
COAST, A SPRAWLING BUBBLE OF HIGH PRESSURE WILL HELP USHER A
COOLER AND DRIER AIR MASS INTO THE REGION.
MEANWHILE, A LOW PRESSURE SYSTEM IS EXPECTED TO GAIN STRENGTH AS
IT TRACKS FROM THE NORTHERN ROCKIES TO THE NORTHERN PLAINS THROUGH
THE DAY ON MONDAY. THIS COMPLEX SYSTEM WILL BRING A COUPLE DAYS OF
UNSETTLED WEATHER FROM THE INTERMOUNTAIN WEST AND ROCKIES TO THE
CENTRAL AND NORTHERN PLAINS. PLENTY OF MOISTURE STREAMING
NORTHWARD AHEAD OF THIS FRONTAL SYSTEM WILL SUPPORT WIDESPREAD
SHOWERS AND THUNDERSTORMS, SOME OF WHICH COULD PRODUCE SEVERE
WEATHER AND HEAVY RAINFALL.
ACROSS THE SOUTH-CENTRAL U.S., AN UPPER LEVEL RIDGE WILL CONTINUE
TO FOCUS DANGEROUSLY HOT WEATHER WITH HIGHS WELL INTO THE 90S AND
LOW 100S. COMBINED WITH LITTLE RELIEF AT NIGHT, SEVERAL DAYS OF
MAJOR TO EXTREME HEATRISK ARE LIKELY, WHICH WOULD INCREASE THE
LIKELIHOOD OF HEAT-RELATED ILLNESSES.
