...COLDER TEMPERATURES AND STRONG GUSTY WINDS TO IMPACT THE
NORTHEAST INTO MONDAY AS SNOW CONTINUES TO IMPACT THE NORTHERN
APPALACHIANS AND PORTIONS OF THE LOWER GREAT LAKES...
...UNSETTLED WEATHER IS EXPECTED TO PERSIST ACROSS THE PACIFIC
NORTHWEST AND INTO THE NORTHERN ROCKIES WITH MULTIPLE ROUNDS OF
LOWER-ELEVATION RAIN AND HIGHER ELEVATION SNOW...
...FIRE DANGER TO INCREASE ACROSS THE CENTRAL AND SOUTHERN HIGH
PLAINS FROM VERY DRY CONDITIONS, GUSTY WINDS, AND WARM
TEMPERATURES...
A STRONG AREA OF LOW PRESSURE WILL CONTINUE TO IMPACT THE
NORTHEAST GOING THROUGH TONIGHT AND EARLY MONDAY WITH AREAS OF
LOCALLY HEAVY SNOW CONTINUING ACROSS PORTIONS OF THE NORTHERN
APPALACHIANS AND ESPECIALLY THE HIGHER TERRAIN FROM THE
ADIRONDACKS OF NEW YORK UP ACROSS THE GREEN AND WHITE MOUNTAINS OF
VERMONT AND NEW HAMPSHIRE RESPECTIVELY. A COMBINATION OF MOISTURE
WRAPPING AROUND THE DEEP LOW CENTER AND MUCH COLDER AIR POURING
SOUTHEAST FROM CANADA WILL RESULT IN LOCALLY AN ADDITIONAL 6 TO 12
INCHES OF SNOW BEFORE THE SNOW BEGINS TO TAPER OFF BY LATER
MONDAY. MEANWHILE, THE COLD AIR POURING SOUTHEAST OVER THE LOWER
GREAT LAKES WILL YIELD A CONTINUATION OF LOCALLY HEAVY LAKE-EFFECT
SNOW SHOWER ACTIVITY AND SQUALLS. PORTIONS OF NORTHWEST
PENNSYLVANIA, WESTERN NEW YORK, AND THE HIGHER TERRAIN OF THE
CENTRAL APPALACHIANS ARE EXPECTED TO SEE A FEW MORE INCHES OF SNOW
THIS EVENING AND OVERNIGHT BEFORE THE ACTIVITY BEGINS TO TAPER OFF
EARLY MONDAY.
IN THE WAKE OF THE GRADUALLY DEPARTING LOW CENTER OVER THE
NORTHEAST, TEMPERATURES TO START OFF THE NEW WEEK WILL BE
GENERALLY BELOW NORMAL ACROSS THE EASTERN SEABOARD AND MOST OF THE
GULF COAST REGION. HIGH PRESSURE WILL SETTLE DOWN ACROSS THE
REGION GOING THROUGH TUESDAY BEFORE THEN GRADUALLY ADVANCING
OFFSHORE. TEMPERATURES ARE EXPECTED TO BEGIN REBOUNDING RATHER
QUICKLY FOR MUCH OF THE EAST AND THE SOUTH BY LATER TUESDAY AS
MILDER AIR FROM THE PLAINS AND MIDWEST ADVANCES EAST AND COUPLES
WITH WARM AIR BEGINNING TO RETURN NORTH FROM THE GULF OF MEXICO.
TEMPERATURES OVER THE NEXT COUPLE OF DAYS WILL BE WELL ABOVE
NORMAL ACROSS ESPECIALLY THE CENTRAL AND NORTHERN PLAINS AND THE
MIDWEST WHICH WILL THEN GRADUALLY ADVANCE INTO THE GREAT LAKES AND
OHIO VALLEY. HIGH TEMPERATURES ACROSS PORTIONS OF EASTERN SOUTH
DAKOTA, MINNESOTA, IOWA, AND WISCONSIN ARE FORECAST TO BE AS MUCH
AS 30 TO 40 DEGREES ABOVE NORMAL ON MONDAY AND TUESDAY WITH
TEMPERATURES APPROACHING OR LOCALLY EXCEEDING 70 DEGREES. SOME
CITIES WILL LIKELY BE WARM ENOUGH TO SEE THEIR DAILY HIGH
TEMPERATURE RECORDS EITHER TIED OR BROKEN.
VERY WARM TEMPERATURES OVER THE CENTRAL AND SOUTHERN HIGH PLAINS
ARE EXPECTED GOING THROUGH THE FIRST HALF OF THE WEEK, AND THIS
COUPLED WITH INCREASINGLY GUSTY WINDS AND LOW RELATIVE HUMIDITY
WILL PROMOTE AN INCREASED RISK OF WILDFIRE ACTIVITY. IN FACT, THE
STORM PREDICTION CENTER HAS HIGHLIGHTED LARGE AREAS OF THE CENTRAL
AND SOUTHERN HIGH PLAINS IN AN ELEVATED TO CRITICAL FIRE DANGER
AREA. THIS WILL INCLUDE THE PANHANDLES OF TEXAS AND OKLAHOMA WHERE
DEVASTATING FIRES OCCURRED A COUPLE WEEKS AGO.
MEANWHILE ACROSS THE PACIFIC NORTHWEST, MULTIPLE LOW PRESSURE
SYSTEMS ARRIVING FROM THE PACIFIC WILL BRING FREQUENT ROUNDS OF
PRECIPITATION ONSHORE AND THEN FARTHER INLAND INTO THE NORTHERN
ROCKIES EARLY THIS WEEK. MODERATE TO LOCALLY HEAVY RAIN IS
EXPECTED FOR THE COASTAL RANGES WITH HEAVY SNOW OVER THE HIGHER
ELEVATIONS OF THE CASCADES, NORTHERN SIERRA NEVADA, AND THE
SAWTOOTH, BITTERROOT, AND TETON RANGES OF THE NORTHERN ROCKIES. AS
MUCH AS 1 TO 2 FEET OF NEW SNOW CAN BE EXPECTED, WITH GENERALLY
THE HEAVIEST TOTALS EXPECTED OVER THE WASHINGTON CASCADES.
