/Issued 4:53 PM CDT, Wednesday, April 18, 2018/
Winter Storm Warning (Pink) and Winter Weather Advisory (Purple) remain in effect tonight south of the Northland.
Today’s snow event has stayed well to the south of the Northland which is good news for us, but bad news for people who live farther south where several inches of snow has fallen today, unless of course you like snow in mid April, then today’s snow has been a good thing!
Warmer in northwest Minnesota compared to southern Minnesota today.
Goes-16 water vapor satellite loop from Wednesday, April 18, 2018 — Quite an intense storm but a small one impacting portions of the upper Midwest and southern Great Lakes today.
12z GEFS model from 4.18.2018 — Temperature Anomaly Forecast valid through May 4, 2018. Note: The blue colors being replaced by orange and red colors — In other words, colder than average temperatures that have been in place for several weeks now will be replaced by near to above average temperatures at least for the rest of this month. Note: Not real sure yet how early May will be around here with conflicting signals per long range models with the Euro Ensemble showing below average temps returning around here for the first few days of May.
Low pressure was over eastern Illinois this afternoon with an upper level low slightly W/NW of the surface low. This system brought significant amounts of snow to parts of South Dakota, Nebraska, Iowa, Minnesota and Wisconsin today while farther north in our area it was mainly dry under partly to mostly cloudy skies. Highs ranged from the mid to upper 30s near Lake Superior to the 40s over the remainder of the Northland, but a few locations were within a degree or two of 50 at 4 PM today.
High pressure will be in control of our weather right through the weekend. Should have quite a bit of sun Thursday through Sunday but there will also be some clouds passing by at times. No precipitation expected through Sunday.
Lows tonight will be in the 20s with single digits and teens possible in the traditional cold spots. Highs Thursday will be in the 40s and 50s, warming to the 50s for Friday, Saturday and Sunday. Some locations in our area could even climb into the lower 60s over the weekend!
Note: Will these milder temperatures even occur by Lake Superior this weekend? It will depend on wind direction (typical for this time of year) Offshore wind will result in the highs in the 50s to around 60 degrees, but an onshore wind (East) would lead to daytime highs staying in the 30s to around 40 degrees by Lake Superior. It’s difficult to get more than one or two days in a row without an east wind near Lake Superior in late April.
