CONTINUED ONSHORE FLOW WITHIN AN ACTIVE JET STREAM CARRYING A

NEARLY CONTINUOUS SNOWFALL FOR THE CASCADE MOUNTAINS OVER THE NEXT
COUPLE OF DAYS. THROUGH THURSDAY EVENING, TWO TO FOUR FEET OF SNOW

NUMBER OF COLD FRONTS MOVE THROUGH THE NORTHWEST, SNOW LEVELS WILL

ACROSS THE CENTRAL AND MUCH OF THE EASTERN U.S., ABOVE AVERAGE

UPPER LEVEL TROUGH ACROSS THE WEST WILL ALLOW FOR UPPER LEVEL
RIDGING TO BUILD DOWNSTREAM ACROSS THE EASTERN U.S. THROUGH
THURSDAY. WARM SOUTHERLY WINDS AT THE SURFACE WILL HELP TO SUPPORT
HIGH TEMPERATURES THAT WILL BE ROUGHLY 15 TO 25 DEGREES ABOVE
AVERAGE FOR MANY LOCATIONS FROM THE GREAT PLAINS TO THE
APPALACHIANS ON WEDNESDAY AND THURSDAY. OVERNIGHT MINIMUM
TEMPERATURE DEPARTURES WILL BE EVEN GREATER, UP TO OR JUST OVER 30
