DAY 1

...NORTHERN/CENTRAL PLAINS AND UPPER MIDWEST...

A PACIFIC SHORT WAVE IMPULSE OVER NORTHERN BRITISH COLUMBIA WILL
SLIDE DOWN NWRLY FLOW ALOFT TO SLICE THROUGH EASTERN MT THIS
EVENING AND PROGRESS THE CENTRAL PLAINS AND MID TO LOWER MS VALLEY
ON SUN. THIS SMALL SCALE FEATURE WILL THEN BE FOLLOWED BY THE NEXT
REINFORCING ARCTIC AIR MASS, AS A POWERFUL COLD FRONT PLUNGES
SOUTH INTO THE UPPER MIDWEST. IN BOTH INSTANCES, VIRTUALLY NO
MOISTURE CONTENT WILL BE AVAILABLE FOR EACH SYSTEM, MAINLY
PRODUCING LIGHT SNOW. THE INITIAL SYSTEM WILL PRODUCE
DYNAMICALLY-DRIVEN LIGHT SNOW FROM EASTERN MT TO EASTERN
KS/WESTERN MO. THE LATTER WILL FEATURE LIGHT BLOWING SNOW
SPREADING OUT ACROSS THE UPPER MS VALLEY STATES AND ALONG THE
TRAILING COLD FRONT FROM SD BACK INTO EASTERN MT. OVERALL THE
GUIDANCE IS VERY SIMILAR WITH MASS FIELDS AND SHORT WAVE DETAIL
DIFFS INCLUDING THE QPF, WHICH IS ANTICIPATED TO GENERALLY BE A
.25 INCH OR LESS EXCEPT IN A NARROW ZONE FROM SERN MT TO THE BLACK
HILLS OF SD.
