...STRONG TO SEVERE THUNDERSTORMS WITH HEAVY RAIN ACROSS THE
SOUTHERN/CENTRAL PLAINS TONIGHT...
...ANOTHER ROUND OF SEVERE THUNDERSTORMS POSSIBLE ACROSS THE UPPER
MIDWEST TO THE GREAT LAKES MONDAY NIGHT INTO TUESDAY MORNING...
...CRITICAL FIRE WEATHER RISK OVER THE CENTRAL/SOUTHERN HIGH
PLAINS ON MONDAY...
A SLOW MOVING LOW PRESSURE SYSTEM WILL BRING RAIN AND MOUNTAIN
SNOW TO MUCH OF THE NORTHWEST THROUGH MONDAY. FROM MONDAY NIGHT
INTO TUESDAY MORNING, THE PRECIPITATION ACROSS THE PACIFIC
NORTHWEST AND THE NORTHERN ROCKIES WILL BEGIN TO TAPER OFF.
HOWEVER, AS THE UPPER-LEVEL LOW DIGS FARTHER INLAND ACROSS THE
DESERT SOUTHWEST TOWARD THE FOUR CORNERS, SCATTERED SHOWERS AND
HIGH-ELEVATION SNOWS WILL ALSO SPREAD ACROSS THESE AREAS.
FOR THE MID-SECTION OF THE COUNTRY, ANOTHER LOW PRESSURE SYSTEM IS
FORECAST TO TRACK ACROSS THE NORTHERN PLAINS BEFORE MERGING WITH A
COLD FRONT DIPPING INTO THE GREAT LAKES TONIGHT. STRONG TO SEVERE
THUNDERSTORMS ALONG WITH HEAVY DOWNPOURS ARE EXPECTED TO MOVE FROM
THE MIDDLE MISSISSIPPI VALLEY TO THE UPPER MIDWEST/GREAT LAKES
TONIGHT. THESE SHOWERS AND THUNDERSTORMS WILL WEAKEN AS THEY MOVE
INTO THE NORTHEAST ON MONDAY. ALSO ON MONDAY, THE SEVERE WEATHER
THREAT REMAINS IN PLACE THROUGH CENTRAL TEXAS WHILE A NEW SEVERE
WEATHER THREAT EMERGES ACROSS THE UPPER MIDWEST LATER THAT DAY.
THIS IS IN RESPONSE TO A LOW PRESSURE WAVE DEVELOPING ALONG A
FRONTAL BOUNDARY. LARGE TO VERY LARGE HAIL, DAMAGING WINDS AND
TORNADOES ARE POSSIBLE. THE SEVERE WEATHER AND HEAVY RAIN THREATS
WILL THEN HEAD EAST ACROSS THE UPPER MIDWEST TO THE GREAT LAKES
MONDAY NIGHT INTO TUESDAY MORNING.
THE WARM AIR ACROSS THE MID-SECTION OF THE COUNTRY WILL EXPAND
EASTWARD OVER THE NEXT COUPLE OF DAYS, WITH POTENTIAL FOR RECORD
BREAKING TEMPERATURES OVER PARTS OF THE MID-ATLANTIC, SOUTHEAST,
MISSISSIPPI VALLEY, AND OHIO/TENNESSEE VALLEY ON MONDAY NIGHT AND
TUESDAY. MEANWHILE, A COOLING TREND WILL GRADUALLY WORK ITS WAY
ACROSS THE WESTERN U.S. WITH ONGOING UNSETTLED WEATHER ASSOCIATED
WITH THE LOW PRESSURE SYSTEM. WARM TEMPERATURES, DRY AIR AND SOME
GUSTY WINDS WILL PROMOTE A CRITICAL RISK OF FIRE WEATHER OVER
PORTIONS OF SOUTHEASTERN COLORADO, NORTHEASTERN NEW MEXICO AND THE
TEXAS/OKLAHOMA PANHANDLES ON MONDAY.
