The Senario from WPC
A DYNAMIC POLAR SHORTWAVE OVER WESTERN
CANADA WILL DIVE SOUTHEASTWARD TO REACH THE UPPER MIDWEST BY
THURSDAY NIGHT. THIS SYSTEM IS FORECAST TO DEEPEN OVER THE UPPER
MIDWEST ON FRIDAY WHILE DEVELOPING A CLOSED 500MB LOW. IN THE
DEFORMATION ZONE OF THE DEVELOPING LOW, SOME DYNAMIC COOLING WITH
THE PRECIPITATION ON THE BACKSIDE OF THE MID-LEVEL CIRCULATION CAN
BE EXPECTED. THE FORECAST CHALLENGE IN AN EARLY SEASON EVENT LIKE
THIS IS THE BOUNDARY LAYER TEMPERATURE.
Accumap is up for the flakes.
Sounding for Longville, MN where the GFS12z showing a few inches

.LONG TERM...(FRIDAY THROUGH WEDNESDAY)
THE SLOWER TREND WITH THIS INCOMING SYSTEM ALSO MEANS MOST OF
FRIDAY COULD BE PRECIP FREE AS WE END UP IN THE DRY SLOT...WITH
THE TRAILING WEAK TROUGH AND UPPER LOW NOT SWINGING THROUGH UNTIL
FRIDAY NIGHT. THE TIMING MIGHT ACTUALLY SUPPORT A FEW MORE SNOW
FLAKES MIXING IN LATE FRIDAY NIGHT AND EARLY SATURDAY MORNING AS
TEMPERATURE PROFILE COLLAPSE AND THE FREEZING LEVEL DROPS TO NEAR
1000FT WHILE THE LIGHT PRECIP IS STILL ONGOING IN THE EASTERN HALF
OF MN AND IN WESTERN WI. THE SURFACE TEMP AND GROUND TEMP ARE TOO
WARM FOR EVEN MINOR ACCUMULATIONS...BUT NONETHELESS WE`RE ABOUT A
COUPLE WEEKS AHEAD OF SCHEDULE FROM WHEN WE TYPICALLY SEE OUR
FIRST FLAKES . THE GFS/NAM/ECMWF/GEM ALL HAVE SNOW ACCUMULATIONS
ACROSS FAR NORTHERN MN [/b]. ...WITH THE POTENTIAL FOR DOUBLE DIGIT
/INCHES/ SNOWFALL IN SOUTHERN MANITOBA AND ONTARIO.

Here's the Current Alerts Map for tonight.
NWS Burlington says The Freeze for parts of Vermont/NY is 1-2 weeks early.
Protect those plants tonight best you can, I think a seasonable trend after this for couple days so I wonder if you can get them to survive through this freeze if they could last till end of September..
Nice cool dry airmass behind the front as it drops south. Should stall and dissipate near Southern Ohio Valley & Mid Atlantic.
This is High pressure dropping down from the Arctic so the airmass is fresh. Cold and Dry with it. North Winds

All models showing this anomalous storm going from Plains to Great Lakes into Canada with some very cold air behind it.
As usual, details changing up to the event, such as exact track, temps, moisture, and such.
Something I'm seeing with this morning's run is backside moisture inside the cold pool of air. While some may see snow"flakes" falling, we may not know without anyone reporting it. Elevations above 2000 feet have much better chances at it from North Dakota to Northern Wisconsin..
Here's latest GFS map for Thursday morning.

POSSIBLY PORTIONS OF NORTHWEST SD.
SKIES ARE EXPECTED TO CLEAR OUT THURSDAY NIGHT...AND WITH COLD AIR

Like a broken record this Summer, another possible Fall/Winter type scenario. (No not snow)
Euro shows a storm curling around a trough heads towards Great Lakes then transfers energy to a coastal low which then heads towards Maine. 1000mb Low. Not a pattern we typically see in the summer.
GFS does not transfer.
Either way ... Rain, Clouds, some wind likely. And temps maybe staying in the 60s during the day in spots in New England on Wednesday. Then the chilly air mass comes in for Thurs-Sunday

TWO FAST MOVING CLIPPER LOWS WILL CROSS THE REGION...EACH WITH A
MODERATE SNOW. THE FIRST WILL BE TODAY...THE SECOND SUNDAY NIGHT
AND MONDAY. EACH WILL BE FOLLOWED BY SURGES OF FRIGID ARCTIC AIR
6:10am Temps and Radar. And Worth it to point out that winds are gusting 15-30mph from Minnesota to Kentucky to Maine
