West to northwesterly winds in the mid to upper levels of the atmosphere helped to carry the high-level clouds or blow-off clouds from thunderstorms in north-central Wisconsin farther to the southeast this afternoon.

There’s been some severe weather in southern portions of the Northland over the last 2 days.

And today’s severe weather was focused on northern Wisconsin with large hail being the main hazard once again.
MRMS rainfall analysis which focuses on the scattered storms which moved through parts of northeast and east-central Minnesota and northwest Wisconsin Monday afternoon/early Monday evening. Note the scattered bands of higher rainfall totals which is very typical for how rainfall patterns setup this time of the year, one area gets quite a bit of rain, while a few miles away there is very little rain to no rain at all!

Today’s cold front which moved through the Northland will return north as a warm front Wednesday night which will be followed by another cold frontal passage Thursday.
We may see a few showers and thunderstorms develop and move across the Northland Wednesday and Wednesday night due to increasing amounts of warm air and moisture advection along with a strong low-level jet which is forecast to setup over parts of the upper Midwest Wednesday night.
The threat for a widespread severe weather event is on the low side Wednesday, but there is a chance for at least isolated strong to severe thunderstorms in much of the Northland with large hail and damaging winds being the primary threats.

Usually by July and August an east wind doesn’t have as great of an effect on temperatures near Lake Superior as an east wind does in May and June, but things may be different this year since Lake Superior continues to run colder than average by some 5-8 degrees!
The warmest year on June 27 for the period (1995-2021) was in 1998 with an average surface water temperature of around 54 degrees.
The coldest year on June 27 for the period (1995-2021) was in 1996 with an average surface water temperature of around 40 degrees.
The average surface water temperature of Lake Superior as of June 27, 2022, was around 41 degrees (average in late June is closing in on 50 degrees)
Note 2022 is running similar to 1996 in terms of the water temperature of Lake Superior, and in 1996 the water temperature of Lake Superior didn’t peak (low 60s) until early September. Usually, Lake Superior is at its warmest in August.
