AN INTENSE LOW PRESSURE SYSTEM, LIKELY REACHING PEAK INTENSITY
EARLY THIS SUNDAY MORNING, HAS CONTINUED TO IMPACT MUCH OF THE
HIGH PLAINS AND NEARBY ROCKIES WITH WINDS LOCALLY GUSTING OVER
HURRICANE FORCE. THE COLD AIR MASS BEHIND THIS INTENSE STORM IS
SUPPORTING WET SNOW ACROSS THE NORTHERN HIGH PLAINS INTO THE
NORTHERN ROCKIES. THE COMBINATION OF WET SNOW IN THE MIDST OF THE
HIGH WINDS HAS RESULTED IN BLIZZARD CONDITIONS LOCALLY OVER
WESTERN NEBRASKA. MEANWHILE, PLENTY OF WARM AIR IS WRAPPING
AROUND THE EASTERN SIDE OF THE STORM WITH BANDS OF SHOWERS AND
THUNDERSTORMS SWEEPING THROUGH THE NORTHERN AND CENTRAL PLAINS.
THE INTENSE STORM IS EXPECTED TO GRADUALLY WEAKEN TODAY AS IT
MOVES GENERALLY TOWARD THE UPPER MIDWEST. MIXED RAIN AND WET SNOW
ARE EXPECTED ACROSS THE NORTHERN PLAINS BY TONIGHT AS SHOWERS AND
EMBEDDED THUNDERSTORMS MOVE INTO THE GREAT LAKES AND DOWN THE
MISSISSIPPI VALLEY BY EARLY ON MONDAY. THE RAIN/SNOW OVER THE
NORTHERN PLAINS IS EXPECTED TO TAPER OFF BY MONDAY NIGHT WHEN THE
LOW PRESSURE SYSTEM WEAKENS FURTHER AND HEADS TOWARD SOUTHERN
CANADA BY TUESDAY MORNING.
MEANWHILE, THE HUGE CIRCULATION ASSOCIATED WITH THE WEAKENING
NOR'EASTER HAS BEEN SLOW TO EXIT NEW ENGLAND, WITH SOME WET SNOW
AND RAIN STILL AFFECTING MAINE AND THE CAPE COD AREA EARLY SUNDAY
MORNING. THE PRECIPITATION IS EXPECTED TO TAPER OFF THIS MORNING
AS THE HUGE STORM BEGINS TO MOVE OUT INTO THE ATLANTIC. COLDER
AIR WRAPPING AROUND THE HUGE STORM WILL LEAD TO BELOW FREEZING
TEMPERATURES AS FAR SOUTH AS THE SOUTHERN APPALACHIANS EARLY THIS
MORNING BEFORE THE APRIL SUN AND THE ARRIVAL WARM AIR FROM THE
INTENSE STORM OVER THE PLAINS SEND TEMPERATURES WELL UP INTO THE
60S TO NEAR 70 BY THIS AFTERNOON.
FOR THE TOTAL SOLAR ECLIPSE THAT IS SCHEDULED TO TAKE PLACE ON
MONDAY, IT APPEARS THAT SOUTHERN TEXAS WILL WAKE UP TO
CONSIDERABLE CLOUDS MONDAY MORNING WITH A RESURGENCE OF WARM AND
MOIST AIR FROM THE GULF OF MEXICO. IN CONTRAST, NEW ENGLAND WILL
LIKELY WAKE UP TO CLEARING SKIES WITH COLD TEMPERATURES INTO THE
20S MONDAY MORNING UNDER A FRESH SNOW COVER FROM THE RECENT
NOR'EASTER. THERE WILL PROBABLY BE SOME BREAKS IN THE CLOUDS FROM
NORTHERN ARKANSAS TO CENTRAL OHIO BEHIND A FRONT, AND MOSTLY
CLOUDY FARTHER NORTHEAST FROM EASTERN OHIO TO WESTERN PORTIONS OF
NEW YORK.
BEGINNING LATE ON MONDAY INTO TUESDAY, A THREAT OF HEAVY RAIN WILL
QUICKLY EMERGE ACROSS THE WESTERN GULF STATES AND THEN EXPANDS
FURTHER INTO THE MID-SOUTH IN RESPONSE TO A RETURN OF GULF
MOISTURE WHICH WILL THEN INTERACT WITH AN UPPER TROUGH ARRIVING
FROM THE SOUTHERN ROCKIES. IN CONTRAST, VERY DRY CONDITIONS
COMBINED WITH STRONG DOWNSLOPE WINDS FROM THE ROCKIES WILL KEEP
FIRE DANGER AT CRITICAL TO LOCALLY EXTREME LEVELS ACROSS THE
CENTRAL TO SOUTHERN HIGH PLAINS WITH SOME IMPROVEMENTS ON MONDAY.
MEANWHILE, MOISTURE FROM THE NEXT PACIFIC SYSTEM IS FORECAST TO
BRING THE NEXT ROUND OF PRECIPITATION INTO THE PACIFIC NORTHWEST
BY LATER ON MONDAY INTO TUESDAY.
