An area of showers and thunderstorms north of the border as of 5:50 PM is moving to the south/southeast and will impact parts of northeast Minnesota this evening, most of the showers should remain east of a line from International Falls to Two Harbors, and a gradual weakening trend is expected as the storms move further south into the Northland through the evening hours. Note: I’m not expecting any rain in Duluth tonight.

Low temperature forecast for Tuesday morning, July 23.
Another pleasant night on the way with lows ranging from around 50 degrees to the lower 60s, but a few of the typical cool spots could fall into the 40s, similar to what happened Monday morning when Hibbing, Silver Bay, Aitkin, Ely and Bigfork reported lows in the lower to middle 40s.
High temperature forecast for Tuesday, July 23.
Temperatures will warm nicely on Tuesday with highs in the upper 70s to lower 80s.
A few showers and thunderstorms will impact far northeast Minnesota tonight (mainly before midnight)
Tuesday will be dry for most of us, but a few spotty afternoon-evening showers and thunderstorms will probably develop across far northeast Minnesota into northwest Wisconsin.
CAPE will generally be less than 1000 J/kg tonight and again Tuesday afternoon with a N-NW flow aloft in place along with around 30 knots of shear and generally weak mid level lapse rates of around 6.0 c/km. Not expecting any severe weather through Tuesday given the ingredients mentioned above, but brief downpours and occasional lightning will occur if you get hit by one of these isolated storms.
Shown below is the HRRR model (18z run) radar forecast valid from 7 PM Monday to 10 PM Tuesday.
Still looks like it will be turning more humid later this week as southerly winds develop ahead of an area of low pressure, warm front and cold front which is forecast to move through the Northland sometime in the Thursday-Friday time frame. Dew points will climb into the 60s to around 70 degrees Thursday, possibly lingering into Friday depending on the timing of the cold frontal passage.
Scattered showers and thunderstorms are possible late this week due to the warm, humid and unstable airmass which will be in place as that low along with its frontal boundaries pass through the area.
A classic warm summer pattern looks to continue around here into early August per long range European Ensemble forecast shown below.
Temperature Anomaly forecast valid through August 6, 2019. Orange and red colors indicate above normal temperatures while blue and green colors indicate below normal temperatures.
A few brief cool downs mixed in, but overall it’s a warm pattern for our area for about the next 2 weeks, enjoy!
