A POTENT COLD FRONT WILL PUSH THROUGH THE MID-ATLANTIC AND

ON THE BACKSIDE OF THE FRONT ACROSS PORTIONS OF THE MID-ATLANTIC
INTO HALLOWEEN (TUESDAY). TEMPERATURES WILL FALL DRAMATICALLY FOR

WILL SUPPORT RAIN/SNOW SHOWERS FOR PARTS OF THE UPPER MIDWEST,
GREAT LAKES AND INTERIOR NORTHEAST THROUGH WEDNESDAY MORNING.
ANOTHER SHOT OF COLD AIR WILL ARRIVE OVER THE NORTHERN/CENTRAL

ROUND OF COLD AIR MAY DROP TEMPERATURES LOW ENOUGH TO CONTEND WITH

PLAINS TO THE MIDWEST. FREEZE WARNINGS ARE ALSO IN EFFECT FROM
NORTHERN TEXAS THROUGH ARKANSAS AND UP INTO MUCH OF THE

THIS WEDNESDAY AFTERNOON/EVENING OVER THE PACIFIC NORTHWEST AS A
LOW PRESSURE SYSTEM AND ASSOCIATED MOISTURE PLUME ARRIVE. THERE
WILL BE FLASH FLOODING CONCERNS ASSOCIATED WITH THIS AR, PARTLY
DUE TO RAIN OVER SNOW PACK IN THE HIGHER ELEVATIONS AS WELL AS
RUNOFF THREATS OVER SATURATED SOILS. DRY/GUSTY CONDITIONS OVER
PARTS OF SOUTHERN CALIFORNIA AND THE SOUTHEAST WILL CONTINUE TO
SUPPORT AN ELEVATED FIRE WEATHER RISK ON TUESDAY.
