DISCUSSION

QUITE THE CHANGE FROM THE RECORD-BREAKING WARMTH OVER THE
WEEKEND AS MUCH COOLER CANADIAN AIR CONTINUES TO SETTLE OVER
THE UPPER MIDWEST. A FEW RAIN SHOWERS HAVE DEVELOPED ACROSS
WESTERN MINNESOTA WHERE CLEARER SKIES LEAD TO SOME SURFACE
INSTABILITY IN ADDITION TO THE COLD CYCLONIC FLOW ALOFT. THESE
SHOWERS WILL CONTINUE INTO CENTRAL & EASTERN MINNESOTA UNTIL
SUNSET, & A RUMBLE OR TWO OF THUNDER CAN'T BE RULED OUT. THE
COOLER TEMPERATURES CONTINUE THROUGH THE REST OF THE WEEK AS
CONTINUED NORTHERLY FLOW & MOSTLY CLOUDY SKIES KEEP
TEMPERATURES MAINLY IN THE 50S TO LOW 60S.
OUR NEXT CHANCE FOR RAIN ARRIVES THURSDAY AS AN UPPER-LEVEL LOW
MOVES NORTHEAST OUT OF THE ROCKIES INTO THE CENTRAL PLAINS.
RAIN SHOULD SPREAD INTO SOUTHERN MINNESOTA & WESTERN WISCONSIN
DURING THE MORNING AND CONTINUE THROUGH THE AFTERNOON & EVENING.
MOST OF THE MOISTURE WITH THIS SYSTEM WILL REMAIN SOUTH OF THE
AREA ACROSS THE MID-MISSISSIPPI VALLEY ALONG WITH THE HEAVIEST
RAINFALL ACROSS IOWA & SOUTHERN MINNESOTA. RAINFALL AMOUNTS
WILL GENERALLY RANGE AROUND 0.25-0.50" ACROSS SOUTHERN
MINNESOTA & WESTERN WISCONSIN & AROUND 0.1" OR LESS FARTHER
NORTH.
A COLDER AIRMASS MOVES INTO THE REGION BEHIND THURSDAYS SYSTEM
AS A STRONG UPPER-LEVEL TROUGH DIGS INTO THE GREAT LAKES & COLD
CANADIAN HIGH PRESSURE MOVES OVER THE UPPER MIDWEST. GUSTY
NORTHWEST WINDS & HIGHS ONLY IN THE LOW TO MID 50S ARE EXPECTED
FRIDAY BEFORE HIGH PRESSURE BRINGS CLEARING SKIES & DIMINISHING
WINDS FRIDAY NIGHT. THIS SETS THE STAGE FOR WIDESPREAD FREEZING
TEMPERATURES SATURDAY MORNING, WITH LOWS GENERALLY IN THE UPPER
20S TO LOW 30S ACROSS MUCH OF CENTRAL & SOUTHERN MINNESOTA AND
WESTERN WISCONSIN. AI WEATHER MODELS CONTINUE TO RUN SEVERAL
DEGREES COLDER THAN THE TRADITIONAL PHYSICAL MODELS & ENSEMBLES
FOR SATURDAY MORNING, WHICH ADDS CONFIDENCE TO THE POTENTIAL FOR
A WIDESPREAD FREEZE BASED ON OBSERVED TRENDS FROM LAST FALL.
THE EXTENT OF THE COLDER TEMPERATURES WILL DEPEND ON HOW QUICKLY
WINDS DIMINISH FRIDAY NIGHT, BUT THIS IS INCREASINGLY LOOKING
LIKE A GROWING SEASON ENDING FREEZE FOR MUCH OF THE AREA.
THE COLD SPELL WILL BE BRIEF AS UPPER-LEVEL RIDGING BUILDS BACK
INTO THE UPPER MIDWEST OVER THE WEEKEND. TEMPERATURES REBOUND
INTO THE UPPER 50S TO LOW 60S THIS WEEKEND, FOLLOWED BY
WIDESPREAD 60S & POTENTIALLY LOW 70S EARLY NEXT WEEK. DRY
WEATHER LOOKS TO CONTINUE INTO NEXT WEEK WITH ONLY A LOW CHANCE
AT SHOWERS & THUNDERSTORMS DEPENDING ON THE TIMING OF A FRONTAL
PASSAGE SUNDAY INTO MONDAY.
