Note: Not sure yet if will get the wind to shift directions in Duluth on Friday, if the wind remains out of the east which is certainly possible, then temperatures Friday afternoon would only be in the 70s to around 80 degrees, cooler near the lake…But, if the wind does shift to the south or southwest, then temperatures by late Friday afternoon would rocket toward 90 degrees in the Twin Ports. Either way it will be muggy on Friday with dew points of 65 to around 75 degrees!

Potential weather pattern for mid to late next week — This pattern if it verifies could be an interesting one for the Northland with potential for some heat, very muggy air and possible clusters of strong to severe thunderstorms and heavy rainfall for mid to late next week. Stay tuned!

•5:28 PM: Hail — 0.25 inch. 7 NW Tower, MN (St. Louis County) Strong winds knocked garden corn crop down.
•4:55 PM: Hail — 0.50 inch. 4 SW Orr, MN (St. Louis County)
A cold front has moved into north central Minnesota early this evening with scattered showers and thunderstorms occurring near that front this afternoon in far northern and northeastern Minnesota. CAPE up to 2000 j/kg was in place in parts of the Northland as of 7 PM along with 30 to 40 knots of deep layer wind shear, this combined with enough convergence near the cold front has allowed for the development of some convection this afternoon. Otherwise today saw a mix of sun and clouds with highs in the upper 70s to around 80 degrees with dew points in the upper 50s to middle 60s so slightly muggy.
A few showers and thunderstorms should persist til around midnight in parts of northeast and east central Minnesota before things settle down overnight, brief heavy downpours, occasional lightning will be the main hazards out of this activity with isolated instances of hail or gusty winds also possible.
Partly to mostly cloudy skies for the rest of tonight with lows in the lower 50s to lower 60s.
The cold front that is over northern Minnesota early this evening will move south into central Minnesota by Thursday morning, this front will more or less stall out through Friday morning while it turns into a warm front. Quite a bit of instability will develop near this warm front on Thursday, this coupled with strong winds aloft and favorable wind shear could lead to a few strong to severe thunderstorms mainly over southern portions of the Northland on Thursday.
A strengthening low level jet develops Thursday night with even stronger instability advecting NE into the Northland. Pretty strong signals showing up on the models for a complex of strong to severe thunderstorms to erupt sometime Thursday night over North Dakota, this activity would then move through parts of northern Minnesota Friday morning the way it looks now. Damaging winds and possibly some hail are possible with the storms Friday morning.
Friday afternoon and evening looks capped with very warm 700mb temperatures of +13 to +16C over the Northland. It also looks very warm and sultry with temperatures Friday afternoon ranging from the middle 80s to middle 90s while dew points range from 67 to 75 degrees! A lake breeze is possible most of Friday near Lake Superior, and if one occurs, then temperatures will be a lot cooler near Lake Superior, probably in the 60s or 70s.
A cold front is forecast to move through the Northland sometime Friday night or Saturday with additional rounds of showers and thunderstorms possible until this front gets far enough to our south/east.
