...A RAPIDLY DEVELOPING COASTAL STORM IS EXPECTED TO BRING A
PERIOD OF GUSTY WINDS AND LOCALLY HEAVY RAIN TO SOUTHEAST VIRGINIA
AND EASTERN NORTH CAROLINA TONIGHT THROUGH FRIDAY MORNING...
...UNSETTLED WEATHER TO CROSS THROUGH MUCH OF THE WEST WITH LOWER
ELEVATION RAIN AND MOUNTAIN SNOW GOING THROUGH FRIDAY AND FRIDAY
NIGHT...
...BELOW NORMAL TEMPERATURES ARE FORECAST FOR MUCH OF THE WEST,
WITH GENERALLY ABOVE NORMAL TEMPERATURES FROM THE PLAINS AND
MIDWEST EASTWARD TO THE EASTERN SEABOARD GOING INTO THE WEEKEND...
A STORM SYSTEM ADVANCING ACROSS THE CENTRAL APPALACHIANS, THE
MID-ATLANTIC STATES, AND PORTIONS OF THE SOUTHEAST WILL BRING RAIN
ACROSS THESE AREAS THROUGH THIS EVENING. HOWEVER, AN AREA OF LOW
PRESSURE IS FORECAST TO STRENGTHEN NEAR THE NORTH CAROLINA OUTER
BANKS TONIGHT WHICH WILL HELP TO BRING MORE CONCENTRATED AREAS OF
HEAVIER RAIN ACROSS SOUTHEAST VIRGINIA AND FAR EASTERN NORTH
CAROLINA ALONG WITH GUSTY WINDS. THIS COASTAL LOW WILL THEN MOVE
OFFSHORE AND AWAY FROM THE EAST COAST BY LATE FRIDAY WHICH WILL
ALLOW FOR THE RAINS TO COME TO AN END. PORTIONS OF THE OUTER BANKS
THOUGH MAY SEE LOCALLY A FEW INCHES OF RAIN BEFORE IT TAPERS OFF.
HIGH PRESSURE WILL THEN ENVELOPE MUCH OF THE EASTERN U.S. IN THE
WAKE OF THIS SYSTEM AND WILL REMAIN ANCHORED IN PLACE GOING
THROUGH THE WEEKEND AHEAD. TEMPERATURES WILL BE COOL ACROSS THE
SOUTHERN MID-ATLANTIC ON FRIDAY WITH AREAS OF LINGERING CLOUDS AND
RAIN, BUT A WARMING TREND WILL GENERALLY BE NOTED ACROSS MUCH OF
THE EAST HEADING INTO THE WEEKEND WITH DRY AIR AND TEMPERATURES
THAT WILL TREND BACK ABOVE NORMAL. THE MILDER AIR WILL BE COMING
FROM AREAS OF THE PLAINS AND MIDWEST WHICH WILL ALREADY BE WELL
ABOVE NORMAL, AND BY THIS WEEKEND, LARGE AREAS OF THE MIDWEST TO
THE APPALACHIANS AND UP INTO THE NORTHEAST WILL SEE HIGH
TEMPERATURES WELL INTO THE 50S AND 60S AND LOCALLY RUNNING 10 TO
15 DEGREES ABOVE NORMAL. UNFORTUNATELY THE RETURN OF DRY AND
WARMER AIR WILL LIKELY MAINTAIN LOCALLY ELEVATED CONCERNS FOR
WILDFIRE ACTIVITY, AND ESPECIALLY AREAS OF EASTERN PENNSYLVANIA
AND NEW JERSEY UP THROUGH ALL OF SOUTHERN NEW ENGLAND.
MEANWHILE, A MUCH MORE UNSETTLED WEATHER PATTERN WILL BE EVOLVING
ACROSS THE WESTERN U.S. AS A STORM SYSTEM CROSSING THE PACIFIC
NORTHWEST AND GREAT BASIN THROUGH TONIGHT MOVES EAST INTO THE
ROCKIES ON FRIDAY. COASTAL/LOW ELEVATION RAINS AND HIGHER
ELEVATION SNOW CAN BE EXPECTED, AND THIS WILL INCLUDE AREAS OF THE
CASCADES DOWN THROUGH THE NORTHERN AND CENTRAL SIERRA NEVADA
SEEING SNOWFALL ACCUMULATIONS. THIS SNOWFALL WILL OVERSPREAD AREAS
OF THE GREAT BASIN AND THE NORTHERN ROCKIES GOING THROUGH FRIDAY
AND FRIDAY NIGHT.
A COLD FRONT ASSOCIATED WITH THIS STORM SYSTEM WILL SWEEP THROUGH
MUCH OF THE WEST AND THEN EJECT OUT INTO THE PLAINS ON SATURDAY AS
LOW PRESSURE THAT WILL INITIALLY BE STRENGTHENING OVER THE
INTERMOUNTAIN WEST ON FRIDAY THEN EJECTS OUT ACROSS THE NORTHERN
PLAINS. BELOW AVERAGE TEMPERATURES THOUGH WILL BE THE THEME ACROSS
MUCH OF THE WEST AND ESPECIALLY OVER THE SOUTHWEST IN THE WAKE OF
THIS FRONT, AND SOME AREAS WILL SEE HIGH TEMPERATURES AS MUCH AS
10 TO 15 DEGREES BELOW NORMAL. HOWEVER, CONVERSELY FOR AREAS AHEAD
OF THIS FRONT ACROSS THE PLAINS, WARM SOUTHERLY WINDS WILL
REINFORCE WIDESPREAD ABOVE AVERAGE TEMPERATURES THAT BY SUNDAY
SHOULD REACH AS HIGH AS 20 DEGREES ABOVE NORMAL. THIS WILL INCLUDE
AREAS OF CENTRAL AND SOUTHERN TEXAS WHERE HIGH TEMPERATURES SHOULD
REACH WELL INTO THE 80S, WITH EVEN PARTS OF THE LOWER RIO GRANDE
VALLEY POTENTIALLY REACHING 90 DEGREES.
