...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PARTS OF
THE NORTHERN PLAINS AND CAROLINAS...

...TEMPERATURES WILL BE 10 TO 15 DEGREES BELOW AVERAGE OVER THE
PACIFIC NORTHWEST...

A STRONG UPPER LEVEL RIDGE WILL CONTINUE TO DOMINATE THE WEATHER
PATTERN OVER THE U.S. FOR THE NEXT SEVERAL DAYS. A STORM SYSTEM
MOVING THROUGH THE PACIFIC NORTHWEST AND WESTERN CANADA WILL BE
FORCED EASTWARD ACROSS THE NORTHERN TIER OF THE U.S. MUCH BELOW
NORMAL TEMPERATURES WILL BE COMMON ACROSS THE PACIFIC NORTHWEST IN
WAKE OF THE COLD FRONTAL PASSAGE TODAY. AS THE STORM SYSTEM MOVES
INTO THE CENTRAL U.S., ACTIVE WEATHER WILL BE CONFINED TO AREAS
ALONG AND AHEAD OF THE OCCLUDED FRONT AND WARM FRONT IN THE
NORTHERN PLAINS AND LATER THE GREAT LAKES. STRONG SUBSIDENCE FROM
THE UPPER RIDGE SHOULD SUPPRESS SHOWER ACTIVITY IN THE CENTRAL
PLAINS THROUGH THE PERIOD EVEN THOUGH A COLD FRONT WILL BE
APPROACHING THE REGION.

IN THE EAST, A FRONTAL BOUNDARY WILL SLOWLY DRIFT SOUTHWARD FROM
THE MID ATLANTIC TO THE SOUTHEAST. SHOWERS AND THUNDERSTORMS ARE
EXPECTED ALONG THE BOUNDARY TONIGHT FROM THE MID ATLANTIC TO THE
CENTRAL GULF COAST. BY TOMORROW SCATTERED THUNDERSTORM ACTIVITY
SHOULD BE LIMITED TO COASTAL AREAS FROM THE CAROLINAS TO TEXAS.

IN THE SOUTHWEST, DIURNALLY DRIVEN SHOWERS AND THUNDERSTORMS ARE
EXPECTED INTO THE WEEKEND. WITH A STRONG UPPER RIDGE IN PLACE TO
THE EAST, TROPICAL MOISTURE WILL BE DRAWN NORTHWARD OFF THE
EASTERN PACIFIC. PRECIPITABLE WATER VALUES NEARING TWO STANDARD
DEVIATIONS ABOVE NORMAL OVER THE REGION WILL ALLOW FOR ISOLATED
HEAVY RAINFALL AND POTENTIALLY FLASH FLOODING.

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PARTS OF
THE NORTHERN PLAINS...

...TEMPERATURES WILL BE 10 TO 15 DEGREES BELOW AVERAGE OVER THE
PACIFIC NORTHWEST...

A FRONT OVER THE NORTHERN ROCKIES TO THE GREAT BASIN WILL MOVE
SLOWLY EASTWARD TO THE UPPER MISSISSIPPI VALLEY BY FRIDAY EVENING.
 MOISTURE WILL BE POOLING AHEAD OF THE BOUNDARY OVER THE NORTHERN
PLAINS TO THE UPPER MISSISSIPPI VALLEY.  AREAS OF SHOWERS AND
THUNDERSTORMS WILL DEVELOP IN THE MOIST AIR OVER THE
CENTRAL/NORTHERN PLAINS THAT WILL MOVE TO THE GREAT LAKES BY
FRIDAY EVENING.  IN ADDITION, SHOWERS AND THUNDERSTORMS WILL
DEVELOP ALONG THE U. S./CANADIAN BORDER FROM THE NORTHERN HIGH
PLAINS ON WEDNESDAY TO THE UPPER MISSISSIPPI VALLEY ON FRIDAY
MORNING.  BY FRIDAY EVENING, THE SHOWERS AND THUNDERSTORMS WILL
EXPAND SOUTHWARD ALONG THE FRONT TO PARTS OF THE MIDDLE MISSOURI
VALLEY.  ADDITIONALLY, UPPER-LEVEL ENERGY MOVING OVER THE PACIFIC
NORTHWEST WILL PRODUCE LIGHT RAIN OVER PARTS OF THE AREA THROUGH
THURSDAY EVENING.

A SECOND FRONT WILL MOVE OFF THE NORTHEAST/MID-ATLANTIC COAST ON
THURSDAY WHILE THE SOUTHERN END OF THE BOUNDARY WILL LINGER OVER
PARTS OF THE CENTRAL GULF COAST AND THE SOUTHEAST THURSDAY
AFTERNOON INTO FRIDAY EVENING.  SHOWERS AND THUNDERSTORMS
DEVELOPING ALONG THE FRONT WILL MOVE OFF THE NEW ENGLAND COAST ON
THURSDAY MORNING.  ADDITIONAL SHOWERS AND THUNDERSTORMS WILL
DEVELOP ALONG THE BOUNDARY OVER THE TENNESSEE VALLEY INTO THE
MID-ATLANTIC ON THURSDAY MOVING OFF THE MID-ATLANTIC COAST ON
FRIDAY MORNING.  SHOWERS AND THUNDERSTORMS WILL ALSO DEVELOP OVER
PARTS OF THE SOUTHEAST ON FRIDAY EVENING.

ELSEWHERE, UPPER-LEVEL ENERGY OVER THE CENTRAL GULF COAST WILL
TRIGGER SHOWERS AND THUNDERSTORMS OVER PARTS OF TEXAS AND THE GULF
COAST THROUGH FRIDAY.  FURTHERMORE, MOISTURE TRAPPED UNDERNEATH AN
UPPER-LEVEL RIDGE OVER THE SOUTHWEST/SOUTHERN ROCKIES WILL PRODUCE
AREAS OF SHOWERS AND THUNDERSTORMS OVER THE AREA ON THURSDAY AND
