THE CHANCE FOR PRECIPITATION, INCLUDING SNOW, SLEET, AND FREEZING

THE MODELS AND ENSEMBLES OVERALL REASONALLY AGREE IN SHOWING THAT
A STRONG NERN PAC MEAN RIDGE WILL ENCOURAGE AMPLIFYING/REINFORCING
WRN US TROUGHING ALOFT NEXT WEEK AS A POTENT SERIES OF SYSTEMS DIG
SHARPLY SOUTHWARD.

SUBSEQUENT NEWD EJECTION OUT ACROSS THE CENTRAL AND
E-CENTRAL US WILL FURTHER SPIN UP DEEPENED LOWS AND ASSOCIATED
FRONTAL SYSTEMS TO FOCUS ORGANIZED PCPN INCLUDING AN EMERGING
SRN/E-CENTRAL TO ERN US HEAVY RAINFALL THREAT. MEANWHILE EXPECT
OVERTOP QUITE A SURGE OF ARCTIC AIR WITH WIDESPREAD RECORD COLD
TEMP POTENTIAL TO INCREASINGLY SPILL DOWN ACROSS MUCH OF THE
NATION NEXT WEEK IN THE WAKE OF SYSTEM PASSAGES. THIS SCENARIO
SETS THE STAGE FOR A PROLONGED PATTERN WITH ACTIVE WINTER WEATHER
THREATS.

CLUSTERING REMAINS BETTER THAN AVG FOR WHAT MAY BE A FAIRLY DEEP
SYSTEM OVER/NEAR ERN MAINE AS OF 12Z FRI. THE 00Z UKMET IS THE
WEAK EXTREME AT THAT TIME WHILE THE 06Z GFS IS SOMEWHAT
WEAKER/MORE ELONGATED THAN THE MAJORITY OF RECENT GFS/ECMWF RUNS.

OVER THE ERN 2/3 OF THE LOWER 48... EXPECT SNOW N AND RAIN CNTRL/S
TO EXPAND IN COVERAGE OVER THE EAST AHEAD OF A COLD FRONT REACHING
THE EAST ON THU. STRENGTHENING LOW PRES TRACKING ACROSS SRN
CANADA/MAINE AND STRONG TRAILING HIGH PRES SHOULD SUPPORT A PERIOD
OF FAIRLY STRONG WINDS WITH TEMPS COLD ENOUGH FOR A PERIOD OF SNOW
TO THE LEE OF THE GRTLKS AND ALONG WWD FACING SLOPES OF THE
NRN-CNTRL APLCHNS.
