FORECAST ANALYSIS AND DISCUSSION
A POWERFUL LOW IS MOVING NORTHEAST INTO THE CHUKCHI SEA FROM E
SIBERIA. CURRENTLY THAT LOW IS APPROXIMATELY 989 MB, BUT WILL
STRENGTHEN TO 978 MB AS IT MOVES NORTHEAST THROUGH THE ARCTIC. AN
ASSOCIATED WARM FRONT WILL MOVE ACROSS THE NW ARCTIC AND INTO THE
ARCTIC TODAY AND TONIGHT, AND THEN INTO THE INTERIOR, AS WELL.
THIS WILL BRING WIDESPREAD SNOWFALL, ALBEIT NOT PARTICULARLY
HEAVY, AS IT MOVES ACROSS THE N MAINLAND. MIXED PRECIP AND LOCAL
FREEZING DRIZZLE WILL OCCUR OVER THE WEST COAST TODAY. A
STATIONARY FRONT WILL THEN PERSIST OVER THE S MAINLAND THROUGH
WEDNESDAY, WITH MORE ROUNDS OF SNOWFALL AND SOME MIXED
PRECIPITATION THROUGH WEDNESDAY.
EXTENDED FORECAST DAYS 4-7
WEDNESDAY, THE FINAL LOW PRESSURE SYSTEM WILL BE MOVING INLAND,
BRINGING WIDESPREAD SNOWFALL TO THE MAINLAND, MIXED WITH SOME
RAIN/SNOW OVER THE S MAINLAND. TEMPS ARE ABOVE AVERAGE PRETTY MUCH
STATEWIDE ON WEDNESDAY. A COLD FRONT MOVES EAST ON THU AND THU
NIGHT WITH A BRIEF DROP IN TEMPS. HOWEVER, THE GLOBAL MODELS
REMAIN CONSISTENT IN BUILDING IN ANOTHER RIDGE ACROSS THE EASTERN
HALF OF THE MAINLAND AND ACROSS THE AK RANGE, SOMETIME FRIDAY AND
MOVING NORTH THROUGH THE WEEKEND. MORE SNOW WILL BE POSSIBLE ALONG
THIS WARM FRONT AS IT MOVES NORTH. AREAS IN THE S INTERIOR LOOK TO
WARM A LOT FOR THE WEEKEND AS THIS LOOKS TO BE A MILD CHINOOK
FLOW.
