THE UPPER LEVEL LOW THAT BROUGHT SNOW A FEW DAYS AGO IS
RETROGRADING NORTHWESTWARD INTO MANITOBA. AN UPPER LEVEL
SHORTWAVE IS CURRENTLY DIGGING ACROSS THE WESTERN HAVE OF THE
STATE ENHANCED BY THE UPPER LOW, THUS HAS LEAD TO LIGHT SNOW AND
FLURRIES ACROSS THE WEST. SNOW FLURRIES ARE FORECAST TO TAPPER
OFF THIS EVENING. SURFACE HIGH PRESSURE IS FORECAST TO MOVE OVER
SOUTHERN SASKATCHEWAN TONIGHT LEADING TO COLD LOW TEMPERATURES.
IN ADDITION CLEARING SKIES WILL HELP ENHANCE RADIATIONAL
COOLING TONIGHT. THUS TEMPERATURES WERE LOWERED TO THE NBM 50TH.
LIGHT WINDS AND COLD TEMPERATURES WILL LEAD TO AROUND -32 WIND
CHILLS ACROSS PORTIONS OF THE NORTHWEST AND NORTH CENTRAL

TEMPERATURES ARE FORECAST TO REMAIN COOL THROUGH THE WEEKEND
WITH HIGH TEMPERATURES RANGING FROM 5 TO 15 DEGREES WHILE THE
SOUTHWEST COULD WARM INTO THE 20S. ANOTHER SHORTWAVE IS FORECAST
TO MOVE THROUGH THE SOUTHWEST SATURDAY, BUT THE ENSEMBLES AND
CAMS HAVE LOWER PRECIPITATION CHANCES. TEMPERATURES ARE FORECAST
TO WARM UP ACROSS THE SOUTHWEST INTO THE 50S WHILE THE
REMAINDER OF THE STATE WILL SIT IN THE 20 TO 30S. THE PATTERN
WILL SHIFT TO NORTHWESTERLY FLOW WITH RIDGING OUT WEST. THERE IS
GOING TO BE A BATTLE OF TWO AIRMASS WITH THE COLDER AIRMASS
KEEPING THE NORTHEAST COLD WHILE THE SOUTHWEST WILL REMAIN WARM
DUE TO RIDGING OUT WEST. THE UNCERTAINTY IS WHERE IS THE
GRADIENT FOR THESE TEMPERATURES GOING TO SET UP. DEPENDING ON
WHAT SIDE OF THE GRADIENT YOU ARE ON WILL DETERMINE IF YOU ARE
COLDER OR WARMER. PRECIPITATION CHANCES ARE FORECAST TO RETURN
MIDWEEK WITH SOME CHANCES FOR SNOW. A RIDGE WILL LIKELY BE
FAVORED TO BUILD EASTWARD BY THE END OF NEXT WEEK FAVORING
WARMER TEMPERATURES. NBM 25TH IS WARMER THAN NORMAL TEMPERATURES
FOR NEXT WEEK THUS GIVING US CONFIDENCE ON A WARMING PATTERN.
