A FRONTAL BOUNDARY EXTENDING ACROSS THE NORTHERN TIER STATES IS
FORECAST TO UNDULATE THROUGH THE NEXT COUPLE DAYS. AS LOW
PRESSURE WAVES FORM ALONG THE FRONT, SHOWERS AND THUNDERSTORMS
WILL DEVELOP AHEAD OF AND NEAR THE TRACKS OF THE WAVES. A COUPLE
OF THESE WAVES WILL LIKELY TRIGGER STRONG TO SEVERE THUNDERSTORMS
WITH HEAVY RAIN FOCUSING ACROSS THE UPPER MIDWEST TO THE GREAT
LAKES REGION FOR TONIGHT INTO TUESDAY MORNING. A LULL IN THE
THUNDERSTORM ACTIVITY IS EXPECTED DURING THE DAY ON TUESDAY BEFORE
ANOTHER ROUND OF STRONG TO SEVERE THUNDERSTORMS WITH HEAVY RAIN
RETURNS LATER ON TUESDAY ACROSS THE MIDWEST/UPPER MIDWEST AND INTO
THE SOUTHERN HALF OF THE GREAT LAKES INTO EARLY WEDNESDAY MORNING.
THE INTERIOR NORTHEAST WILL ALSO SEE A COUPLE OF ROUNDS OF
SHOWERS AND THUNDERSTORMS. THE FIRST ROUND IS EXPECTED TODAY
AHEAD OF A WARM FRONT FOLLOWED BY A COLD FRONT. THE NEXT ROUND
SHOULD BRING A HIGHER RISK OF STRONG TO SEVERE THUNDERSTORMS
TUESDAY NIGHT AHEAD OF THE NEXT LOW PRESSURE WAVE.
AS THE FRONT UNDULATES ACROSS THE NORTHERN TIER STATES, RETURN
FLOW FROM A STRONG RIDGE OF HIGH PRESSURE EXTENDING FROM BERMUDA
WILL PROMOTE ROUNDS OF STRONG TO SEVERE THUNDERSTORMS FROM THE
SOUTHERN PLAINS TO THE MIDWEST THROUGH THE NEXT COUPLE OF DAYS.
THE BERMUDA HIGH WILL ALSO BRING ANOMALOUS WARMTH INTO THE EASTERN
U.S. HIGH TEMPERATURES WELL INTO THE 80S WILL BEGIN TO CHALLENGE
DAILY RECORDS IN THE EAST-CENTRAL U.S. BY TUESDAY AFTERNOON. BY
WEDNESDAY MORNING, RECORD WARM TEMPERATURES WILL BE WIDESPREAD
FROM THE EAST-CENTRAL U.S. TO NEW ENGLAND.
THE RECENT ROUND OF HEAVY MOUNTAIN SNOW AND LOW-ELEVATION RAIN
ACROSS CALIFORNIA WILL BEGIN TO TAPER OFF TODAY AS A LOW PRESSURE
SYSTEM MOVES FARTHER INLAND AND WEAKENS. MEANWHILE, THE NORTHERN
INTERMOUNTAIN REGION WILL GET A ROUND OF HIGH-ELEVATION SNOW AND
LOWER-ELEVATION RAIN TODAY AS THE NORTHERN EDGE OF THE LOW
PRESSURE SYSTEM INTERACTS WITH A FRONT ARRIVING FROM CANADA.
UNSETTLED WEATHER WILL THEN SHIFT FOCUS TO THE FOUR CORNERS ON
TUESDAY AS THE UPPER LOW/TROUGH PENETRATES FARTHER INLAND.
PACIFIC NORTHWEST WILL ALSO SEE THE NEXT ROUND OF RAIN AND
HIGH-ELEVATION SNOW ARRIVING ON TUESDAY AHEAD OF THE NEXT PACIFIC
SYSTEM. THE PRECIPITATION IS EXPECTED TO BE HEAVIER ALONG WITH
WINDY CONDITIONS TUESDAY NIGHT WITH THE PASSAGE OF A FRONT.
AS THE WARM AIR EXPANDS EASTWARD FROM THE PLAINS TO THE EASTERN
U.S. OVER THE NEXT COUPLE OF DAYS, A COOLING TREND WILL GRADUALLY
WORK ITS WAY ACROSS THE WESTERN U.S. WITH THE ONGOING UNSETTLED
WEATHER. WARM TEMPERATURES, DRY AIR AND SOME GUSTY WINDS WILL
PROMOTE A CRITICAL RISK OF FIRE WEATHER OVER THE CENTRAL TO
SOUTHERN HIGH PLAINS AND NEARBY SOUTHERN ROCKIES OVER THE NEXT
COUPLE OF DAYS.
