Northwest flow aloft continued today with another disturbance passing through the Northland which brought some light rain showers to the area — Mostly cloudy skies today although there’s been some peeks of sun every now and then. Still cool with highs today in the mid 50s to low 60s but it was warmer farther west with Brainerd getting into the lower 70s this afternoon with 80s over the Dakotas.
We’re entering a stretch of dry weather which will begin late tonight and continue through the weekend and possibly beyond! Lingering showers will move out of northeast Minnesota and northwest Wisconsin this evening, and this will be followed by some clearing overnight along with chilly temperatures as lows fall into the 30s and 40s, maybe even some 20s in the typical cold spots.
More sunshine Friday, Saturday and Sunday (Compared to what we’ve seen recently)
Highs Friday ranging from around 60 near Lake Superior to the mid 60s/near 70 degrees elsewhere. Highs Saturday are forecast to range from the low 60s to low 70s. Highs Sunday mainly in the 70s with 60s along the North Shore of Lake Superior.
Note: There is a chance that high temps next Monday and Tuesday climb well into the 70s, perhaps even up near 80 degrees in our area with S-SW winds (Will see if this trend continues to show up on the computer models in coming days)
Note: About the only weather issue besides the frost potential late tonight will be the threat for low clouds/fog late at night which could linger into the morning hours (Tonight, Friday and Saturday)
