A wet and cool start to July. Low pressure is moving quickly northeast out of western Wisconsin this afternoon. This is a very dynamic system especially considering the time of year. A rather strong baroclinic zone was in place today with 850mb temps of +12C in northeast Minnesota to +20C in far eastern Wisconsin. 12-hour 500mb height falls of 60 meters covered most of the Northland this afternoon, quite impressive for July! Strong convergence and divergence on the west/northwest side of the surface low today which caused widespread rain in northeast Minnesota and in parts of northwest Wisconsin. The good news is that this system is moving quickly through the area and rain is already ending from SW-NE late this afternoon. Because of the extensive rain and clouds today, highs were on the cool side with temperatures generally in the 60s in northeast Minnesota and northwest Wisconsin.
Rain ends early this evening in northeast Minnesota and northwest Wisconsin followed by some clearing, then partly to mostly cloudy skies for the overnight period with patchy fog possible, lows in the 50s to lower 60s. Could see a few showers or thunderstorms late tonight mainly in northern Minnesota thanks to yet another disturbance which moves east out of North Dakota tonight.
Majority of the day Monday looks nice under partly to mostly sunny skies, shouldn’t be too humid with dew points generally in the 50s to lower 60s. Southwesterly breezes with highs in the upper 70s to middle 80s.
Changes take place once again Monday night as a warm front sets up to our southwest. Low level jet increases which will transport moist and unstable air north into our area — Should see at least isolated to perhaps scattered coverage of showers and thunderstorms over the Northland Monday night into Tuesday morning with a risk of a few strong to severe thunderstorms producing large hail and damaging winds.
Additional rounds of showers and thunderstorms are possible Tuesday afternoon into the 4th of July (Wednesday) with dry hours mixed in.
Forecast for Duluth and Superior
.Tonight… Breezy this evening. Partly to mostly cloudy. Isolated showers possible overnight. Low 56 to 61. Wind northwest at 10 to 20 mph with gusts to 25 mph, decreasing to 10 to 15 mph and becoming south to southwest late.
.Monday… Partly cloudy. High 80 to 85. Wind southwest at 10 to 20 mph. Showers and thunderstorms possible Monday night.
.Tuesday… Partly to mostly cloudy. Showers and thunderstorms possible mainly early. High 78 to 83 but cooler near Lake Superior. Wind south to southeast at 10 to 20 mph.
