...TEMPERATURES WILL BE 20 TO 30 DEGREES ABOVE AVERAGE OVER PARTS
OF THE GREAT LAKES,OHIO VALLEY, AND THE NORTHEAST...
...THE PACIFIC NORTHWEST WILL BE UNSETTLED AS AREAS OF LOW
PRESSURE MOVE THROUGH THE REGION AND BRING COASTAL RAIN AND
MOUNTAIN SNOW...
...THERE WILL BE A POTENTIAL FOR SOME HEAVY RAIN AND LOCALLY
STRONG THUNDERSTORMS OVER THE CENTRAL AND SOUTHEASTERN U.S. THE
NEXT COUPLE OF DAYS....
A STRONG SURFACE HIGH PRESSURE CENTERED IN THE CAROLINAS WILL LEAD
TO ANOMALOUSLY WARM TEMPERATURES ACROSS MUCH OF THE OHIO AND
TENNESSEE VALLEYS FOR THE REMAINDER OF WEDNESDAY AND THE EAST
COAST ON THURSDAY. MANY STATIONS MAY ECLIPSE DAILY RECORD HIGH
TEMPERATURES WITH HIGHS RANGING FROM THE MIDDLE 80S IN KENTUCKY TO
NEAR 80 IN MICHIGAN FOR THE REMAINDER OF TODAY. ON THURSDAY,
HALLOWEEN, MUCH OF THE NORTHEAST WILL BE CLEAR AND QUITE WARM AS
MORE STATIONS APPROACH OR BREAK DAILY RECORD HIGH TEMPERATURES
WITH THE THERMOMETER APPROACHING THE LOW 80S. AS STATED IN THE KEY
MESSAGE, THIS IS AS MUCH AS 20-30 DEGREES ABOVE AVERAGE SO WEAR A
COOL COSTUME IF CELEBRATING THE HOLIDAY ACROSS THE EAST. THE
TEMPERATURES SHOULD START TO MODERATE ACROSS THE OHIO VALLEY TO
THE EAST COAST AS A FRONT CLEARS THE REGION AND BRINGS THE CHANCE
FOR RAIN ON FRIDAY.
MEANWHILE, THE WEST COAST WILL BE COOL AND RAINY THE NEXT SEVERAL
DAYS WITH THE PASSAGE OF A COUPLE OF FRONTAL LOWS. HIGH
TEMPERATURES LOOK BE IN THE LOW TO MIDDLE 50S ACROSS THE COASTAL
REGIONS AND INTERIOR LOCATIONS, ESPECIALLY HIGH ELEVATIONS, MAY BE
IN THE 40S AND 30S.THROUGH FRIDAY NIGHT, THE QPF FORECAST CALLS
FOR SEVERAL INCHES OF RAINFALL TO BE POSSIBLE, MOST LIKELY IN THE
2-4 INCH RANGE. NOT ALL PRECIPITATION WILL BE RAIN. THE COLD FRONT
WILL BRING FALLING SNOW LEVEL HEIGHTS AND MOUNTAIN SNOW TO THE
RANGES OF WASHINGTON, OREGON, AND NORTHERN CALIFORNIA. AS THE
SYSTEM MOVES EASTWARD THURSDAY, THE SNOW POTENTIAL WILL INCREASE
FOR EASTERN OREGON, NEVADA, AND IDAHO. AS MUCH AS A FOOT OF SNOW
MAY FALL IN THE MOUNTAIN RANGES OF EASTERN OREGON AND IDAHO.
IN BETWEEN THE COOL AIR IN THE WEST AND WARM IN THE EAST, THE
CENTRAL U.S. WILL BE PRIME FOR STRONG THUNDERSTORMS AND AN
ISOLATED FLASH FLOODING THREAT. FOR THE REMAINDER OF THE DAY
WEDNESDAY, THE STORM PREDICTION CENTER HAS A ENHANCED RISK FOR
SEVERE WEATHER ACROSS EASTERN KANSAS, OKLAHOMA, AND WESTERN
MISSOURI. HAZARDS INCLUDE STRONG WINDS, LARGE HAIL, AND PERHAPS A
STRONG TORNADO OR TWO. THE SEVERE THREAT SHOULD DECREASE THURSDAY
AS THE STORMS MOVE EASTWARD FROM TEXAS TO ILLINOIS, BUT THE THREAT
FOR SOME GUSTY WINDS REMAIN. THE THREAT FOR SOME SEVERE WEATHER
EXISTS AGAIN ON FRIDAY ACROSS THE SOUTHWESTERN PLAINS AS A TROUGH
ENTERS THE REGION AND CONDITIONS LOOK MORE FAVORABLE FOR POTENTIAL
HAIL. IN ADDITION TO SEVERE WEATHER, THERE DOES EXIST SOME
OPPORTUNITY FOR SOME AREAS TO SEE FLASH FLOODING. THE SOUTHERN
MISSISSIPPI RIVER VALLEY IS UNDER A MARGINAL EXCESSIVE RAINFALL
OUTLOOK ON THURSDAY AND EASTERN NEW MEXICO, OKLAHOMA, AND NORTH
TEXAS ARE UNDER A MARGINAL EXCESSIVE RAINFALL OUTLOOK ON FRIDAY.
IT IS POSSIBLE ANY LOCALLY HEAVY THUNDERSTORM COULD DROP MORE THAN
2 INCHES OF RAINFALL.
FOR AREAS NOT INCLUDED IN THE DISCUSSION,MUCH OF THE SOUTHWEST
WILL BE PLEASANTLY MILD AND MOSTLY DRY WITH HIGH TEMPERATURES IN
THE 70S AND LOW 80S. THE SOUTHEAST WILL BE WARM AND HUMID WITH
HIGHS IN THE 80S WITH SOME ISOLATED THUNDERSTORMS POSSIBLE ALONG
THE FLORIDA ATLANTIC COAST.
