...COOLER TEMPERATURES WITH LOWER HUMIDITY FOR THE NORTHEASTERN
STATES...

...HEAVY RAIN AND THUNDERSTORMS EXPECTED ACROSS TEXAS...

MUCH OF THE NORTHEAST AND MID-ATLANTIC STATES WILL CONTINUE TO
HAVE COOLER AND DRIER CONDITIONS THROUGH MONDAY WITH SURFACE HIGH
PRESSURE OVER THE REGION. AN EXTENSIVE LOW PRESSURE SYSTEM
TRAVELING NORTH/NORTHEAST WILL DRAG A COLD FRONT THROUGH THE UPPER
MISSISSIPPI VALLEY, MIDWEST AND SOUTHERN PLAINS, WHILE A WARM
FRONT LIFTS THROUGH THE GREAT LAKES, OHIO AND TENNESSEE VALLEYS.
SCATTERED TO WIDESPREAD PRECIPITATION IS EXPECTED AHEAD OF THE
FRONT.

THE HEAVIEST RAINFALL IS FORECAST FOR PORTIONS OF TEXAS, WHERE A
SLOW MOVING FRONT INTERCEPTS A RICH FLOW OF MOISTURE SURGING NORTH
FROM THE WESTERN GULF OF MEXICO. AN UPPER LEVEL LOW TO THE WEST
WILL HELP PROVIDE ADDITION LIFT. RAINFALL AMOUNTS OF 2 TO 4 INCHES
WILL BE COMMON, WITH ISOLATED HIGHER AMOUNTS OVER THE NEXT 3 DAYS.
A MODERATE RISK OF FLASH FLOODING WILL CONTINUE THROUGH MONDAY
MORNING, WITH A SLIGHT RISK THROUGH TUESDAY MORNING.

THE DEEP SOUTH AND SOUTHEAST U.S. ARE EXPECTED TO REMAIN RATHER
WARM AND HUMID FOR THIS TIME OF YEAR WITH HIGHS IN THE UPPER 80S
TO MID 90S. MEANWHILE, THE PACIFIC NORTHWEST COASTAL AREAS WILL
HAVE SHOWERS AHEAD OF AN APPROACHING PACIFIC COLD FRONT.
