...SEVERE WEATHER THREAT RETURNS TO THE NORTHERN AND CENTRAL
PLAINS ON TUESDAY, FOLLOWED BY SEVERE WEATHER AND HEAVY RAIN/FLASH

...MORE HIGH-ELEVATION SNOWS EXPECTED ACROSS THE PACIFIC NORTHWEST
INTO THE NORTHERN AND CENTRAL ROCKIES FOR THE NEXT COUPLE OF
DAYS...
...WARMER THAN AVERAGE TEMPERATURES ACROSS THE SOUTHERN TIER

THE WEATHER PATTERN THAT KEEPS SENDING FAST-MOVING DISTURBANCES
ACROSS THE WESTERN U.S. WILL CONTINUE TO FORM NEW LOW PRESSURE
SYSTEMS IN QUICK SUCCESSION OVER THE MID-SECTION OF THE COUNTRY
THROUGH THE NEXT COUPLE OF DAYS. THE LATEST LOW PRESSURE SYSTEM
THAT BROUGHT SEVERE WEATHER AND FLASH FLOOD EMERGENCIES OVER
EASTERN TEXAS, TOGETHER WITH WIDESPREAD COLD RAIN ACROSS THE
NORTHERN U.S., TO WET SNOW NEAR THE CANADIAN BORDER, WILL WEAKEN
AS IT TRACKS NORTHEAST ACROSS THE GREAT LAKES INTO SOUTHERN CANADA
ON TUESDAY. MEANWHILE, THE HEAVIEST THUNDERSTORMS AND SEVERE
WEATHER ASSOCIATED WITH THE TRAILING FRONT HAD MOVED OFF THE
LOUISIANA COAST. LESS INTENSE SHOWERS AND THUNDERSTORMS ARE
EXPECTED TO PUSH EASTWARD ACROSS THE MID-SOUTH, TENNESSEE AND OHIO
VALLEYS TOWARD THE APPALACHIANS AND NEW ENGLAND ON TUESDAY, BEFORE
BECOMING MORE WIDELY SCATTERED ALONG THE EASTERN SEABOARD INTO
WEDNESDAY MORNING. SNOWFALL ON THE ORDER OF 6-12 INCHES ARE
FORECAST TO ACCUMULATE OVER PARTS OF THE CASCADES AND NORTHERN
ROCKIES INCREASING TO NEARLY 2 FEET OVER THE HIGHER ELEVATIONS OF
GLACIER NATIONAL PARK.
AS THE SURGE OF COLD AIR PUSHES THROUGH THE NORTHWEST ON TUESDAY
WITH THE LEADING COLD FRONT REACHES THE NORTHERN AND CENTRAL
PLAINS, A COUPLE OF LOW PRESSURE SYSTEMS ARE FORECAST TO DEVELOP.
THE LOW PRESSURE SYSTEM THAT WILL MOVE ACROSS THE UPPER MIDWEST
WILL BRING A THREAT OF SEVERE THUNDERSTORMS ACROSS THE NORTHERN
AND CENTRAL PLAINS AHEAD OF THE TRAILING COLD FRONT ON TUESDAY.
ANOTHER LOW PRESSURE SYSTEM WILL DEVELOP OVER THE CENTRAL PLAINS
ON TUESDAY, THIS SYSTEM WILL BRING A HIGHER THREAT OF SEVERE
WEATHER AND MORE WIDESPREAD HEAVY RAIN THREAT FARTHER SOUTH INTO
THE CENTRAL PLAINS LATER ON WEDNESDAY AS THE SYSTEM INTENSIFIES.
TEMPERATURE-WISE, FAST-MOVING COLD UPPER TROUGHS PROPAGATING
THROUGH THE NORTHWEST AND NORTHERN PLAINS/UPPER MIDWEST WILL KEEP
THINGS COOLER THAN AVERAGE TODAY. MORE COLD AIR WILL PUSH THROUGH
THE PACIFIC NORTHWEST ON WEDNESDAY. MEANWHILE, A WARMING TREND
WILL SEND AFTERNOON TEMPERATURES AS HIGH AS THE LOWER 90S FOR THE
NEXT COUPLE OF AFTERNOONS ACROSS THE CENTRAL TO SOUTHERN HIGH
PLAINS. TEMPERATURES WILL ALSO BE WELL ABOVE AVERAGE ALONG THE
EAST COAST ON TUESDAY FOLLOWED BY A SLIGHT COOL DOWN ON WEDNESDAY
AS A BACK-DOOR COLD FRONT DIPS SOUTH FROM NEW ENGLAND.
