A SURFACE LOW OVER EASTERN CANADA WILL CONTINUE TO LIFT
NORTHEASTWARD ON SUNDAY, WHILE ITS ASSOCIATED COLD FRONT WILL
CONTINUE TO BRING THUNDERSTORMS AND SHOWERS ACROSS THE COASTLINE
OF THE NORTHEAST, MID-ATLANTIC AND SOUTHEAST STATES. MOST OF THE
FRONT WILL MOVE OFF THE COAST BY LATE SUNDAY NIGHT, WITH A PORTION
OF THE FRONT STALLING OVER FLORIDA, WHICH WILL CONTINUE TO BRING

HUMIDITY, WHICH WILL BRING ELEVATED FIRE WEATHER CONCERNS OVER
SOUTHEAST COLORADO AND PORTIONS OF NEW MEXICO FOR SUNDAY.
ANOTHER LOW PRESSURE SYSTEM WILL MOVE ACROSS THE THE UPPER

BRING CHANCES FOR A WINTRY MIX ACROSS THE GREAT LAKES AND
NORTHERN/CENTRAL PLAINS. A WEAK SHORTWAVE TROUGH WILL BRING SOME
MOISTURE OVER PORTIONS OF THE SOUTHWEST ON MONDAY INTO TUESDAY,
WITH CHANCES FOR LIGHT SNOW ACCUMULATIONS OVER HIGHER TERRAIN.
TEMPERATURES OVER MUCH OF EASTERN U.S. WILL BECOME COOLER BEHIND
THE COLD FRONT ON SUNDAY, WHILE WESTERN U.S. CONTINUES TO SEE
ABOVE NORMAL TEMPERATURES. COLD AIR FROM CENTRAL CANADA WILL
REINFORCE FURTHER COOLING, BRINGING TEMPERATURES BETWEEN 20S AND
30S OVER PARTS OF NORTHERN PLAINS AND UPPER MIDWEST ON MONDAY.
THESE BELOW NORMAL TEMPERATURES WILL GRADUALLY PUSH EASTWARD AS
THE CLIPPER SYSTEM MOVES INTO THE NORTHEAST, LOWER GREAT LAKES,
AND OHIO VALLEY ON TUESDAY.
