WATER VAPOR IMAGERY THIS AFTERNOON HIGHLIGHTS THE UPPER TROUGHS IN
NORTHEAST PROVINCES OF CANADA WHILE UPSTREAM NORTHWEST FLOW
STRETCHES THROUGH THE MIDWEST. FOCUS TURNS TOWARDS A SHORTWAVE
TROUGH SHIFTING INTO THE INTER-MOUNTAIN WEST BEFORE LIFTING
SOUTHEAST THROUGH THE PLAINS THURSDAY. A BACK DOOR FRONT COLD FRONT
IS PROGGED TO ARRIVE BY THE MORNING, RESULTING IN NORTHEAST WINDS
AROUND 10 MPH AND HIGHS STRUGGLING TO REACH THE MID 20S. BY THE LATE
MORNING, INCREASING MID LEVEL MOISTURE WITH SOME WEAK FRONTOGENESIS
(850-700MB) MAY LEAD TO VERY LIGHT SNOW OVER FAR NORTHEAST KANSAS.
TIMING OF THIS FORCING AMID THE LOW LEVEL MOISTURE AND SOME DRIER
AIR ATTEMPTING TO EVAPORATE MOST OF THE QPF BEFORE REACHING THE SFC.
OUTSIDE THE NAM, MOST GUIDANCE IS DRY THROUGHOUT THE DAY. ADDED
SLIGHT POPS ON THURSDAY, HOWEVER ANTICIPATE NO ACCUMULATIONS.
THE ARCTIC AIRMASS DIGS IN FRIDAY INTO SATURDAY AS HIGHS ARE IN THE
TEENS AND OVERNIGHT LOWS ARE MOSTLY IN THE SINGLE DIGITS. SURFACE

CLEARING SKIES AND LOWS TO PLUMMET AROUND 5 DEGREES BELOW ZERO.
CONFIDENCE REMAINS MODERATE FOR ADVISORY LEVEL WIND CHILLS RANGING
FROM 10 TO 15 DEGREES BELOW ZERO. IN TERMS OF PRECIPITATION,
ADDITIONAL LIGHT SNOW CHANCES RETURN, MOSTLY ACROSS NORTH CENTRAL
KANSAS, ON FRIDAY AS AN ADDITIONAL MID-LEVEL FRONTOGENETICAL BAND
TRAVERSES SOUTHEAST AROUND THE BACKSIDE OF THE UPPER LOW. LITTLE
MOISTURE TO WORK WITH LENDS TO LOW CONFIDENCE IN ANY ACCUMULATIONS,
MOST LIKELY WEST OF THE AREA WITH NBM SNOWFALL PROBABILITIES LESS
THAN 0.5 INCH (80-90%) FROM CONCORDIA TO MINNEAPOLIS.
NEXT WEAK SYSTEM TO NOTE ROUNDS THE UPPER RIDGE BEFORE REACHING THE
CENTRAL PLAINS ON SATURDAY EVENING. OVERALL ENSEMBLES ARE VARIED ON

PROBABILITIES HAVE BEEN CONSISTENT IN SNOWFALL GREATER THAN 0.1
INCHES BEING 20 PERCENT, DOWN TO LESS THAN 10 PERCENT FOR 0.5 INCHES
OR MORE NEAR THE KANSAS/NEBRASKA BORDER. THE 20-30 POPS STILL SEEM
REASONABLE, HIGHEST BEING NORTH OF I-70.
A STRONGER SHORTWAVE TROUGH ENTERS SOMEWHERE OFF THE PACIFIC
NORTHWEST COAST OVER THE WEEKEND, ENTERING THE REGION IN THE TUESDAY-
WEDNESDAY TIME FRAME. ORIENTATION OF THE WAVE AND DEGREE OF FORCING
GREATLY VARIES AMONG ENSEMBLES WHILE TEMP SPREADS AMONG THE NBM ARE
NOT SURPRISING (10-15 DEGREE DIFFERENCE) WITH INDICATIONS FOR PRECIP
TYPE BEING RAIN INITIALLY AS FORECAST HIGHS REACH THE LOW 40S. IF
