21z RAP model – Temperature forecast for Wednesday morning at 7 AM.
Monday’s winter storm that impacted parts of the northern Plains and upper Midwest continues to move toward the south/east today. Looks impressive on this Goes-16 true color satellite loop.
18z NAM model – 500mb vorticity forecast through early Saturday morning. Numerous upper level lows dancing around, finally merging into one main upper low over the northeast U.S. by the end of the week. Awesome stuff!

Strong height falls covered areas from Ontario Province to the central Great Lakes and Ohio Valley down into parts of the southeast U.S. thanks to two strong upper level lows, one was over western Illinois, the other just north of Lake Superior. Heights are on the rise this afternoon over the northern Plains and parts of the upper Midwest behind Monday’s winter storm. Lots of sun this afternoon over most of the Northland but clouds along with some snow flurries continued near Lake Superior due to the northeast flow coming off the lake.
Cold air advection will take place over our area tonight with 850mb temperatures dropping to around -14 to -16C. An upper low will swing south out of western Ontario Province tonight but this feature shouldn’t produce any snow even though it looks quite impressive on satellite imagery today. The main story for our area the next few days will be high pressure which will slowly approach from the northern Plains. Will have partly to mostly cloudy skies tonight through Thursday with cold overnight lows and below normal high temps for the next few days. Lake effect snow showers and flurries are expected tonight and Wednesday along the South Shore of Lake Superior with the cold air and northerly flow over the lake.
Low temperatures tonight will be in the single digits below to around 10 above zero, highs Wednesday will be in the 20s which is about 5 to 8 degrees colder than average for early March.
Note: Our next chance for a little bit of snow could come this weekend but the computer models are not in agreement with this system. GFS model is up to its old trick in forecasting copious amounts of snow while the German-Icon model also shows some snow this weekend although not to the extent as what the GFS shows, and then we have the EURO model which is a no-show (no snow for you type scenario)
