...MORE ROUNDS OF EXCESSIVE RAINFALL AND SEVERE WEATHER EXPECTED
TO PUSH EAST AND SOUTHEAST TOWARD THE LOWER MISSISSIPPI VALLEY
THROUGH TONIGHT INTO MONDAY...
...HIGH-ELEVATION SNOW IS FORECAST TO OVERSPREAD THE PACIFIC
NORTHWEST INTO THE NORTHERN ROCKIES MONDAY AND TUESDAY...
...WARMER THAN AVERAGE TEMPERATURES SPREAD FROM MIDWEST TO
MID-ATLANTIC; COLDER WEATHER RETURNS TO THE NORTHERN PLAINS AND
THE PACIFIC NORTHWEST WITH WARMING TREND ACROSS THE
CENTRAL/SOUTHERN HIGH PLAINS...
MORE ACTIVE AND UNSETTLED WEATHER IS FORECAST TO CONTINUE ACROSS
THE MID-SECTION OF THE COUNTRY THROUGH THE NEXT COUPLE OF DAYS AS
MULTIPLE DISTURBANCES EMBEDDED WITHIN A SLOW-MOVING UPPER-LEVEL
TROUGH TRAVERSE THE WESTERN U.S. TOWARD THE GREAT PLAINS. THE LOW
PRESSURE SYSTEM RESPONSIBLE FOR THE LATEST OUTBREAK OF STRONG TO
SEVERE THUNDERSTORMS ACROSS THE CENTRAL TO SOUTHERN PLAINS TODAY
WILL CONTINUE TO TRACK NORTHEAST ACROSS THE UPPER MIDWEST ON
MONDAY. ANOTHER BOUT OF STRONG TO SEVERE THUNDERSTORMS CAN BE
EXPECTED TO IMPACT AREAS FARTHER EAST ACROSS THE ARKLATEX REGION
THROUGH TONIGHT AS THE TRAILING COLD FRONT ASSOCIATED WITH THE LOW
PRESSURE SYSTEM EDGES FARTHER TO THE EAST. IN ADDITION, HEAVY
DOWNPOURS ASSOCIATED WITH THESE STORMS WILL RESULT IN FLOODING
CONCERNS ACROSS THE REGION. BY MONDAY, THE HIGHEST THREAT OF
SEVERE WEATHER AND HEAVY RAIN WILL SHIFT FARTHER SOUTHEAST TOWARD
TO CENTRAL GULF COAST REGION, MAINLY OVER LOUISIANA, AS THE FRONT
BEGINS TO WEAKEN. A LOWER RISK OF SEVERE WEATHER AND HEAVY RAIN
WILL EXTEND FARTHER NORTHEAST INTO THE TENNESSEE VALLEY ON MONDAY.
MEANWHILE, WIDESPREAD COLD RAIN IS EXPECTED TO CONTINUE THROUGH
TONIGHT ACROSS THE NORTHERN PLAINS, UPPER MIDWEST AND TOWARD THE
LOWER GREAT LAKES AHEAD OF THE LOW PRESSURE SYSTEM AND THE
ASSOCIATED WARM FRONT, WITH EMBEDDED THUNDERSTORMS CLOSER TO THE
CENTER OF THE LOW. TEMPERATURES COULD BE COLD ENOUGH TO SUPPORT
WET SNOW MONDAY MORNING ACROSS PORTIONS OF THE NORTHERN PLAINS
INTO THE UPPER MIDWEST. THE RAIN WILL THEN SHIFT EASTWARD INTO
THE WESTERN PORTION OF NEW ENGLAND, DOWN ACROSS THE OHIO VALLEY
TOWARD THE APPALACHIANS ON TUESDAY AS THE LOW CENTER MOVES INTO
SOUTHERN CANADA.
ON THE WARM SIDE OF THE LOW PRESSURE SYSTEM, STRONG SOUTHERLY FLOW
WILL BRING VERY WARM AIR NORTHWARD INTO THE EAST COAST THROUGH THE
NEXT COUPLE OF DAYS WITH HIGH TEMPERATURES CLIMBING WELL INTO THE
80S AND POSSIBLY INTO THE LOWER 90 DEGREES FOR THE INTERIOR
MID-ATLANTIC. THESE TEMPERATURES WILL BE IN CONTRAST TO THE COOL
TEMPERATURES EXPECTED FOR THE PACIFIC NORTHWEST BY MONDAY AS THE
NEXT UPPER-LEVEL TROUGH FROM THE PACIFIC IS FORECAST TO PUSH
INLAND. THIS TROUGH WILL BRING WIDESPREAD HIGH-ELEVATION SNOW AND
LOWER ELEVATION RAIN ACROSS THE PACIFIC NORTHWEST TOWARD THE
NORTHERN ROCKIES ON MONDAY WITH INCREASINGLY WINDY CONDITIONS AS A
LOW PRESSURE SYSTEM BEGINS TO DEVELOP OVER THE NORTHERN HIGH
PLAINS INTO SOUTHERN CANADA. BY TUESDAY, THE MAIN FRONT WILL MOVE
FAIRLY QUICKLY ACROSS THE NORTHERN AND CENTRAL PLAINS, WITH RAPID
DEVELOPMENT OF SHOWERS AND THUNDERSTORMS EXPECTED ACROSS THE UPPER
MIDWEST IN THE AFTERNOON AHEAD OF A WARM FRONT AND A LOW PRESSURE
WAVE. SOME THUNDERSTORMS MAY BEGIN TO ERPUT ACROSS THE CENTRAL
PLAINS INTO TEXAS EAST OF A DRY LINE. FARTHER WEST, WARM
DOWNSLOPE WINDS FROM THE SOUTHERN ROCKIES WILL SET A WARM TREND
ACROSS THE SOUTHERN HIGH PLAINS WITH HIGH TEMPERATURES REACHING
INTO THE 80S AND LOWER 90S BY TUESDAY AFTERNOON.
