* No major storms in sight this week - next chance of any accumulation will be Sunday-Monday, when an inch or two can't be ruled out.
* Temperatures this week run a few degrees below average (normal high now is 40 at MSP)
* Next week: much colder: highs in the 20s and low 30s (potentially one of the colder Thanksgivings in recent memory).
From the Chanhassen office of the National Weather Service - a great recap of Saturday's freakish (100 mile wide) snow blitz:
"Three days after a record high temperature of 68° in the Twin Cities, the weather turned around quite fiercely with the first winter storm of the season. A low pressure area moved from northern Missouri on the night of the 12th to western Wisconsin by the morning of the 14th. This was near to a classic path of what is called a "Panhandle Hooker" low pressure area for Minneapolis to receive at least six inches of snow. Snow would begin late the night of the 12th and persist through the day on the 13th for much of central and southern Minnesota into northwestern Wisconsin. As for near Eau Claire, snow changed to rain by daybreak Saturday morning, and the rain persisted for much of the day on Saturday. Precipitation of nearly two inches was observed during the weekend there. The snowfall rates across southern and eastern Minnesota were most explosive between 5 am and noon on the 13th. During that time window, lightning was observed across southern and eastern Minnesota into western Wisconsin with very heavy snowfall rates. Very high moisture content created a wet and heavy snowfall. While ground temperatures were warm and led to some melting, the heavy snowfall rates quickly overcame that. While snowfall began to taper Saturday evening, moisture wrapping around the low pressure area in Wisconsin helped to continue sporadic bursts of accumulating snow."
Event Climate Facts
- 8.0" was officially observed at the Minneapolis/St. Paul International Airport.
- This was the largest pre-Thanksgiving, as well as November snowfall, for the Twin Cities since the "Halloween Blizzard" of October 31-November 2, 1991.
- Since 1997, this was only the third six inch or greater official snowfall in the Twin Cities during meteorological autumn (Sept-Nov).
Southerly Clippers. With prevailing jet stream winds howling from the northwest conditions won't be ripe for significant storms anytime soon. This week's clipper takes a track far enough south to spare Minnesota - Iowa may see a mix of snow/ice/rain by midweek.
