...HEAVY RAINS EXPECTED FOR NORTHERN NY STATE AND NEW ENGLAND
THURSDAY EVENING INTO FRIDAY, AND OVER THE PACIFIC NORTHWEST
FRIDAY INTO SATURDAY...
...TRICK OR TREATING WILL BE DRY ACROSS MUCH OF THE LOWER 48,
EXCEPT FOR COASTAL WASHINGTON/FAR NORTHERN COASTAL OREGON,
NORTHERN NEW YORK STATE INTO NORTHWEST NEW ENGLAND AND OVER THE
UPPER MISSISSIPPI VALLEY...
...BELOW AVERAGE TEMPERATURES EXPECTED ACROSS AREAS TO THE EAST OF
THE ROCKIES, WHILE ABOVE AVERAGE TEMPERATURES EXPECTED FROM THE
ROCKIES TO THE WEST COAST...
THE STRONG STORM SYSTEM THAT HAS BROUGHT HEAVY PRECIPITATION OVER
THE PAST FEW DAYS ACROSS THE MISSISSIPPI VALLEY/LOWER MISSOURI
VALLEY, THROUGH THE OHIO VALLEY, APPALACHIANS, AND MID-ATLANTIC
WILL CONTINUE TO PRODUCE WIDESPREAD WET WEATHER AS IT PUSHES
NORTHEASTWARD INTO THE NORTHEAST/NEW ENGLAND THURSDAY EVENING INTO
FRIDAY. WIDESPREAD HEAVY RAINS LIKELY FROM EASTERN AND NORTHERN
NEW YORK STATE INTO NEW ENGLAND FROM THURSDAY AFTERNOON INTO EARLY
FRIDAY. THE FLOOD THREAT FROM THIS SYSTEM REMAIN VERY LOW AS
DROUGHT CONDITIONS HAVE RESULTED IN LOW STREAM FLOWS AND DRY
SOILS. THE EXCEPTION WILL BE OVER URBANIZED AREAS OF THE
NORTHEAST WHERE A PERIOD OF HEAVY RAIN ALONG AND AHEAD OF THE
ASSOCIATED COLD FRONT THURSDAY AFTERNOON INTO THURSDAY EVENING MAY
RESULT IN ISOLATED URBAN RUNOFF ISSUES. HEAVY RAINS ALSO LIKELY
TO SPREAD INTO PORTIONS OF THE PACIFIC NORTHWEST FRIDAY INTO EARLY
SATURDAY AS AN ATMOSPHERIC RIVER EVENT IMPACTS THESE AREAS. AT
THE MOMENT, IT DOES NOT APPEAR TO BE A PROLONGED EVENT, LIMITING
THE POTENTIAL FOR VERY HEAVY TOTALS AND KEEPING ANY FLOODING RISK
AT A MINIMUM.
MUCH OF THE COUNTRY WILL HAVE GOOD TRICK OR TREATING WEATHER
FRIDAY EVENING/NIGHT. THE EXCEPTIONS WILL BE FOR AREAS OF WESTERN
WASHINGTON STATE INTO FAR NORTHERN COASTAL OREGON, NORTHERN NY
STATE INTO NORTHWEST NEW ENGLAND AND OVER PORTIONS OF THE UPPER
MISSISSIPPI VALLEY.
TEMPERATURE WISE, A COOL WEATHER PATTERN IS ON TAP FOR MOST AREAS
TO THE EAST OF THE ROCKIES OVER THE NEXT TWO DAYS FROM THE
COMBINATION OF COOL AIR IN THE WAKE OF THE SYSTEM PUSHING THROUGH
THE EAST CURRENTLY AND A REINFORCING COLD AIR MASS SINKING SOUTH
FROM THE NORTHERN PLAINS INTO THE UPPER TO MID MS VALLEY AND OHIO
VALLEY. IN CONTRAST, AREAS FROM THE ROCKIES TO THE WEST COAST
WILL SEE MOSTLY ABOVE AVERAGE TEMPERATURES AND DRY WEATHER OVER
THE NEXT FEW DAYS, SAVE FOR THE ABOVE MENTIONED REGIONS OVER THE
PACIFIC NORTHWEST THAT WILL SEE WET WEATHER FRIDAY INTO SATURDAY.
ACROSS AREAS WHERE TEMPERATURES WILL BE ABOVE AND BELOW AVERAGE
OVER THE NEXT FEW DAYS, NO WIDESPREAD REGIONS OF RECORD HIGHS OR
LOWS ARE EXPECTED.
