...SLIGHT RISK OF SEVERE WEATHER FOR NORTHEAST/SOUTHERN
PLAINS/NORTHERN ROCKIES TODAY...

...COOLER TEMPERATURES FOR NORTHEAST/GREAT LAKES AND HOT FOR MUCH
OF THE PLAINS...

A HOT AND HUMID AIRMASS IN PLACE ACROSS THE EASTERN U.S. WILL
SUPPORT STRONG THUNDERSTORM DEVELOPMENT THIS AFTERNOON ALONG AND
AHEAD OF THE ADVANCING COLD FRONT. THE STORM ENVIRONMENT WILL BE
MORE CONDUCIVE TO ORGANIZED THUNDERSTORM ACTIVITY ACROSS THE
NORTHEAST WHERE AN UPPER LEVEL JET MAX WILL PROVIDE ENHANCED LIFT
IN THE REGION. THE COLD FRONT WILL DRIFT SLOWLY OFF THE NORTHEAST
COAST AND THROUGH THE MID ATLANTIC BY TOMORROW AFTERNOON. BELOW
NORMAL HIGH TEMPERATURES WILL BE COMMON ACROSS THE GREAT LAKES,
NORTHEAST, AND MID ATLANTIC ON THURSDAY AS COOLER AIR FILTERS IN
BEHIND THE FRONT AND SHOWERS, THUNDERSTORMS, AND CLOUDS ALONG THE
FRONT STUNT DIURNAL HEATING.

A STRONG UPPER LEVEL LOW APPROACHING THE PACIFIC NORTHWEST WILL
BRING HEAVY RAIN TO THE HIGHER TERRAIN AND COOLER TEMPERATURES TO
MUCH OF THE NORTHWEST U.S. MUCH OF THE PRECIPITATION WITH THIS
STORM SYSTEM WILL REMAIN NORTH OF THE BORDER, BUT HEAVY RAINFALL
IS EXPECTED ALONG THE HIGHER TERRAIN OF THE PACIFIC NORTHWEST AND
NORTHERN ROCKIES. SEVERE WEATHER IS POSSIBLE TODAY ACROSS THE
NORTHERN ROCKIES AND NORTHERN HIGH PLAINS. A STRONG JET AND
APPROACHING MID LEVEL SHORTWAVE ENERGY WILL PROVIDE EXTRA LIFT FOR
MORE ORGANIZED STORMS TO DEVELOP. STRONG WESTERLY FLOW OVER THE
CENTRAL AND NORTHERN ROCKIES WILL LEAD TO RISING TEMPERATURES
ACROSS THE PLAINS. TEMPERATURES WILL BE AT OR NEAR 100 FROM TEXAS
TO MONTANA BEFORE A COLD FRONT COOLS THINGS OFF IN THE NORTHERN
PLAINS TOWARD THE END OF THE PERIOD.
