VALID 00Z MON NOV 06 2023 - 00Z WED NOV 08 2023
...MORE UNSETTLED WEATHER EXPECTED TO BRING BENEFICIAL
PRECIPITATION ACROSS THE PACIFIC NORTHWEST AND THE NORTHERN
ROCKIES OVER THE NEXT COUPLE OF DAYS...
...MIXED LIGHT RAIN AND SNOW WILL BRUSH THE NORTHERN BORDERS OF
THE NORTHERN PLAINS TO THE INTERIOR NORTHEAST...
...FAIR AND MILD WEATHER EXPECTED TO CONTINUE FROM THE
SOUTHWESTERN U.S. TO MUCH OF THE EASTERN U.S; COOL PACIFIC AIR
ARRIVES OVER THE WEST BY TUESDAY....
MORE UNSETTLED WEATHER IS FORECAST TO MOVE ACROSS THE PACIFIC
NORTHWEST INTO THE NORTHERN ROCKIES THROUGH TUESDAY WITH THE
ARRIVAL OF A COUPLE MORE UPPER-LEVEL TROUGHS FROM THE EASTERN
PACIFIC. THE LEADING SHORTWAVE WILL SPREAD RAIN AS FARTHER SOUTH
AS NORTHERN CALIFORNIA BY TONIGHT WHILE LOCALLY HEAVY RAIN IS
FORECAST TO REACH COASTAL SOUTHWESTERN OREGON INTO NORTHWESTERN
CALIFORNIA WHERE A MARGINAL RISK OF FLASH FLOODING IS IN PLACE.
FROM MONDAY THROUGH TUESDAY MORNING, THE HEAVIEST PRECIPITATION IS
FORECAST TO REACH FARTHER INLAND NEAR/ALONG THE CASCADES AS WELL
AS FARTHER SOUTH ALONG THE SIERRA NEVADA WHERE WET SNOW CAN BE
EXPECTED CLOSE TO THE HIGHEST PEAKS. THIS MOISTURE SURGE WILL
THEN PENETRATE INLAND, KEEPING A GOOD CHANCE OF LIGHT TO MODERATE
RAIN SHOWERS AT LOW ELEVATIONS AND SNOW OVER ELEVATED TERRAIN
ACROSS THE INTERMOUNTAIN WEST AND THE NORTHERN ROCKIES THROUGH
TUESDAY.
MEANWHILE, SHORTWAVE ENERGY EJECTING OUT OF THE WESTERN U.S. WILL
LEAD TO THE FORMATION OF A PAIR OF CLIPPER LOW PRESSURE SYSTEMS
FARTHER DOWNSTREAM. THE FIRST SYSTEM WILL TRACK QUICKLY EAST
ACROSS THE NORTHERN PLAINS TONIGHT AND ACROSS THE GREAT LAKES ON
MONDAY. A ROUND OF MIXED LIGHT RAIN AND SNOW CAN BE EXPECTED NEAR
THE NORTHERN BORDERS OF THE NORTHERN PLAINS TO THE UPPER GREAT
LAKES THROUGH MONDAY NIGHT. ON THE OTHER SIDE OF THE INTENSIFYING
SYSTEM, SOME WINTRY PRECIPITATION IS FORECAST TO REACH NORTHERN
NEW ENGLAND MONDAY NIGHT AHEAD OF A WARM FRONT BEFORE MILDER AIR
FROM THE SOUTH CHANGES THE PRECIPITATION TO RAIN DURING THE DAY ON
TUESDAY. IN THE MEAN TIME, THE SECOND CLIPPER SYSTEM DEVELOPING
ON THE LEE SIDE OF THE NORTHERN ROCKIES WILL SPREAD THE NEXT ROUND
OF MIXED RAIN AND SNOW ONCE AGAIN NEAR THE NORTHERN BORDER OF THE
NORTHERN PLAINS MONDAY NIGHT INTO TUESDAY. RAIN IS FORECAST
FARTHER SOUTH FROM THE GREAT LAKES ON MONDAY TO MUCH OF INTERIOR
NEW ENGLAND ON TUESDAY.
AS THE UNSETTLED WEATHER CONTINUES OVER THE PACIFIC NORTHWEST,
FAIR AND MILD WEATHER WILL CONTINUE FROM THE SOUTHWESTERN U.S.
THROUGH THE CENTRAL AND SOUTHERN PLAINS AS WELL AS MUCH OF THE
EASTERN U.S. FOR THE NEXT FEW DAYS THANKS TO A RELATIVELY ZONAL
UPPER-LEVEL FLOW ACROSS THE SOUTHERN TIER OF THE COUNTRY. IN
FACT, THERE IS AN INCREASING CHANCE OF RECORD HIGH TEMPERATURES
ESPECIALLY OVER THE CENTRAL TO SOUTHERN HIGH PLAINS BY TUESDAY
AFTERNOON, AND AS FAR EAST AS THE INTERIOR SOUTHEAST. BY TUESDAY,
A COLD AIR MASS WILL BE USHERED INTO THE WESTERN U.S. FOLLOWING
THE PASSAGE OF THE LAST PIECE OF SHORTWAVE ENERGY BEHIND A STRONG
COLD FRONT.
