..HEAVY RAINS EXPECTED OVER THE CENTRAL STATES
AN ACTIVE WEATHER PATTERN IS IN STORE FOR MUCH OF THE UNITED
STATES OVER THE NEXT FEW DAYS AS AIRMASSES FROM DIFFERENT REGIONS
CLASH OVER THE NATION. UNSEASONABLY COLD AIR FROM CANADA WILL
CONTINUE TO POUR DOWN THE EASTERN SLOPES OF THE ROCKIES...WITH
SEVERAL BOUTS OF SNOW EXPECTED FROM MONTANA TO COLORADO. AN UPPER
LEVEL CIRCULATION THAT HAS BEEN SITTING WEST OF BAJA CALIFORNIA
WILL EJECT ACROSS THE SOUTHWESTERN STATES AND INSTIGATE A LOW
PRESSURE WAVE ALONG THE LEADING EDGE OF THE CANADIAN AIRMASS OVER
THE CENTRAL PLAINS AND MID MISSISSIPPI VALLEY. THIS LOW PRESSURE
SYSTEM WILL DRAW WARM...MOIST AIR NORTHWARD FROM THE GULF OF
MEXICO...FUELING WIDESPREAD HEAVY RAINS ALONG AND TO THE NORTH OF
ITS PATH. THE FAR NORTHEAST WILL BE BLUSTERY WITH SHOWERS MAINLY
OVER THE MOUNTAINS IN THE WAKE OF THE BIG STORM CHURNING EAST OF
NOVA SCOTIA.
