AREAS CENTRAL AND WEST LATE TONIGHT...AND EASTERN AREAS FRIDAY
MORNING. TOTAL SNOWFALL ACCUMULATIONS OF ABOUT AN INCH OR SO ARE
ANTICIPATED FOR MOST LOCATIONS BY MID-DAY FRIDAY. DUE TO THE
TIMING OF THE INCOMING SYSTEM...EXPECTING ANOTHER NON-STANDARD DIURNAL
TREND WITH TEMPERATURES FALLING DURING THE EVENING...AND THEN WARMING
THROUGH THE LATE EVENING AND OVERNIGHT HOURS. THE MAIN DIFFERENCE BTWN
THE INCOMING SHORT-WAVE AND LAST NIGHTS WAVE IS MID-LEVEL MOISTURE
AVAILABILITY. CURRENT SYSTEM HAS MORE MOISTURE TO WORK WITH AND

SEVERAL HOURS AFTER SUNSET...LIMITING RADATIONAL COOLING AND
INCREASING DENDRITIC SNOW GROWTH.

THE NEXT SHORT-WAVE TROUGH TO AFFECT THE REGION WILL MOVE THROUGH
LATE-DAY SATURDAY. THIS WAVE AND THE ASSOCIATED ATMOSPHERIC LIFT
ARE FARTHER WEST...BRINGING THE BEST CHANCES FOR ACCUMULATING SNOW
TO AREAS WEST OF THE MISSOURI RIVER.

A SOMEWHAT ACTIVE PATTERN CONTINUES INTO THE EXTENDED PERIOD WITH
A COUPLE WAVES OF ENERGY DROPPING SOUTH IN THE NORTHWEST FLOW
ALOFT. STILL SOME TIMING ISSUES TO SORT OUT WITH THE SUNDAY AND

EC IS A BIT STRONGER AND FORMS A CLOSED LOW AT 500MB WHICH DROPS
SOUTH AND LINGERS SNOW THROUGH THE DAY MONDAY. WILL HAVE TO WATCH
THIS TREND AND IF MODELS LATCH ONTO THIS...WILL NEED TO EXTEND
POPS FOR MONDAY. THE REST OF THE EXTENDED IS DRY RIGHT NOW AS
THERE ARE HINTS THE PATTERN MAY QUIET DOWN AND BECOME A TAD
WARMER. GENERALLY ACCEPTED HPC GUIDANCE TEMPS FOR THE LATTER
PORTIONS OF THE EXTENDED...AND MADE LITTLE CHANGES TO TEMPS
OVERALL.
