...LOW PRESSURE SYSTEM TO BRING LOCALLY HEAVY RAIN AND GUSTY WINDS
FOR THE NORTHEAST TODAY...
...WINDY, COLDER, AND UNSETTLED WEATHER TO SPREAD ACROSS THE
NORTHERN TIER STATES FOR THE NEXT COUPLE OF DAYS...
...UNSEASONABLE OCTOBER WARMTH CROSS THE SOUTHERN PLAINS TO START
THE WEEK WITH HIGHS CLIMBING WELL INTO THE 80S AND 90S...
AN ACTIVE WEATHER PATTERN IS IN PROGRESS ACROSS THE NATION TO
START THE NEW WEEK. THIS ACTIVE WEATHER PATTERN IS SPEARHEADED BY
AN INTENSIFYING LOW PRESSURE SYSTEM THAT IS MOVING SWIFTLY NORTH
OF THE GREAT LAKES INTO SOUTHERN CANADA THIS MORNING. MEANWHILE,
A POTENT COLD FRONT TRAILING SOUTH FROM THE CYCLONE CENTER WILL
INTERACT WITH AN UPPER TROUGH THAT IS DIPPING INTO THE
APPALACHIANS, LEADING TO THE DEVELOPMENT OF ANOTHER LOW PRESSURE
SYSTEM. THIS NEW SYSTEM IS FORECAST TO BRING A ROUND OF RAIN,
LOCALLY HEAVY AT TIMES, AND POSSIBLY EMBEDDED WITH A FEW
THUNDERSTORMS ACROSS NEW ENGLAND TODAY. IN THE WAKE OF THIS
SYSTEM, BREEZY, COOLER, AND DRIER CONDITIONS WILL BE FILTERING
INTO THE EASTERN U.S. THROUGH TONIGHT BEFORE TEMPERATURES QUICKLY
REBOUND ON TUESDAY AHEAD OF THE NEXT LOW PRESSURE SYSTEM
APPROACHING FROM THE NORTHERN PLAINS.
THE AFOREMENTIONED LOW PRESSURE SYSTEM OVER THE NORTHERN PLAINS IS
CURRENTLY IN THE DEVELOPMENTAL STAGE. THIS SYSTEM IS FORECAST TO
EXPAND IN SIZE AND MOVE EASTWARD TO REACH THE GREAT LAKES ON
TUESDAY. MOUNTAIN SNOW ACROSS THE NORTHERN ROCKIES ON THE
BACKSIDE OF THIS SYSTEM IS EXPECTED TO TAPER OFF TODAY.
MEANWHILE, AREAS FROM THE NORTHERN HIGH PLAINS EASTWARD TO THE
GREAT LAKES CAN EXPECT A PERIOD OF RAIN TO ACCOMPANY THE PASSAGE
OF THE LOW, FOLLOWED BY COLDER AND WINDY CONDITIONS ESPECIALLY
ACROSS THE NORTHERN PLAINS THROUGH TONIGHT. THE WINDY CONDITIONS
WILL SPREAD EAST INTO THE UPPER MIDWEST AND OHIO VALLEY TUESDAY
INTO WEDNESDAY ALONG WITH A COLD RAIN FALLING THROUGHOUT THE GREAT
LAKES. SCATTERED AREAS OF RAIN WILL ALSO REACH THE MID-ATLANTIC
AND ESPECIALLY NEW ENGLAND OVERNIGHT TUESDAY INTO WEDNESDAY
MORNING.
TO THE SOUTH OF THIS SYSTEM, BRISK WINDS DESCENDING THE SOUTHERN
ROCKIES WILL MAKE FOR A VERY WARM AFTERNOON ACROSS THE SOUTHERN
PLAINS ON TODAY WHERE HIGHS ARE FORECAST TO REACH WELL INTO THE
80S AND 90S, WHICH IS ROUGHLY 10 TO 20 DEGREES ABOVE NORMAL FOR
MID TO LATE OCTOBER. THESE TEMPERATURES WILL ALSO BE HIGH ENOUGH
TO CHALLENGE SOME DAILY RECORDS. DRY WEATHER WILL REMAIN THE RULE
ACROSS THE SOUTHWEST AND THE FOUR CORNERS WITH A GRADUAL WARMING
TREND SPREADING FURTHER NORTHWARD INTO THE ROCKIES THROUGH
MIDWEEK. MEANWHILE, CHANCE OF SHOWERS AND THUNDERSTORMS WILL
GRADUALLY DECREASE ACROSS THE SUNSHINE STATE AS THE TRAILING COLD
FRONT WEAKENS WITH TIME.
