Potential for strong to severe thunderstorms returns to the Northland on Wednesday, especially for Wednesday night-early Thursday morning the way it looks now. Could see a bow echo of some sort move south/east out of Ontario Province or northwest Minnesota late Wednesday night with a threat for damaging winds and hail in parts of northeast Minnesota and northwest Wisconsin.

Patchy fair weather cumulus clouds along with a batch of generally high level clouds passing through southern portions of the Northland this afternoon while skies are mainly sunny in northern Minnesota. Also note the brownish color over southern Lake Superior, that’s sediment left behind from the mid June flood event, yes it’s still there weeks later!
Here are some pictures I’ve taken over the last week or so, enjoy!

A much more comfortable day with much drier air over our area compared to Sunday’s steam bath. Dew point temperatures this afternoon ranged from the upper 40s to around 60 degrees, this is 10 to 20 degrees lower compared to Sunday afternoon.
Partly sunny to sunny skies prevailed today with highs in the upper 70s to middle 80s.
A nice night ahead under clear to partly cloudy skies, lows ranging from the lower 50s to lower 60s.
Could see a few showers pass through parts of the Northland Tuesday thanks to some Frontogenesis in the 700-850mb layer that will move through the area along with some energy which moves east/southeast out of North Dakota — Any showers that develop shouldn’t last long and I’m not expecting any heavy downpours. Mostly cloudy to partly sunny skies Tuesday with highs in the 70s to lower 80s.
Southerly flow develops Tuesday night ahead of a warm front which moves closer to western Minnesota. Scattered showers and thunderstorms are possible across the Northland late Tuesday night, lingering into Wednesday morning. Not expecting any severe weather Tuesday night or Wednesday morning but some heavy downpours could occur.
Note: The risk for strong to severe thunderstorms increases a bit for Wednesday night into early Thursday morning as a cold front sweeps through the Northland. Deep moisture will also be in place ahead of this front, so the potential for heavy rain and some flooding exists as well. Stay tuned!
