Weather Summary for Northeast Minnesota and Northwest Wisconsin
Date: June 29, 2015
An active day in parts of the Northland as low pressure, cold front, and an upper level system dropped south into the Upper Midwest. Decent heating and moisture were in place with temperatures in the 70s and lower 80s with dew points in the 50s and lower 60s. The atmosphere became unstable with CAPE of around 1000-1500 j/kg and Lifted Indices of -2 to -6C. Mid level winds were up around 30 knots with an upper level wind maximum of 90 knots over the Red River Valley region. Effective Bulk Shear and 0-6 KM Shear were generally in the 30-40 knot range today. All of these ingredients combined with cold temperatures aloft (500mb temps around -13C) were favorable for the development of scattered thunderstorms over parts of the Northland today. Quite a few of these storms were on the strong side with isolated severe storms as well. Large hail and gusty winds along with torrential rainfall and dangerous lightning strikes were common with the storms today.
Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Short Term Forecast – Confidence: High.
Tonight (June 29)
Low pressure and cold front will continue to push south/east and away from the Northland tonight. Widely scattered showers or thunderstorms will dissipate this evening otherwise look for partly to mostly cloudy skies tonight with patchy fog. Low temperatures will be in the 50s to lower 60s with winds out of the north, northwest, or east at 5 to 15 mph.
Tuesday and Tuesday Night (June 30)
The last day of June 2015 will end on a quiet note as high pressure builds south from Ontario. Partly cloudy skies are forecast this period with highs in the 60s and 70s but it will be cooler near Lake Superior. Lows Tuesday Night will be in the 40s and 50s. Winds will be out of the east at 5 to 15 mph.
Note: Smoke from fires in Canada has found its way into the Northland due to a northwest flow aloft. There is a chance that this smoke will linger in Northland skies over the next few days as the winds aloft stay out of the northwest or north/northwest. Low level flow will turn east however, and this may help to produce less smoky conditions in parts of the area Tuesday and Wednesday, will just have to wait and see.
Note: Easterly flow coming off Lake Superior may lead to some fog and low clouds Tuesday and Wednesday near the lake.
Extended Forecast – Confidence: High.
Wednesday through Friday (July 1-3)
Looks mainly dry on Wednesday with highs in the 70s but cooler temperatures will continue near Lake Superior, lows Wednesday Night will mainly be in the 50s. A few spotty showers or thunderstorms are possible on Thursday and Friday as low pressure passes through Central Canada while a cold front trailing southwest of this low moves into the Upper Midwest later this week. High temperatures on Thursday and Friday are expected to be in the 70s and maybe even a few 80s with lows Thursday Night in the 50s and 60s.
Long Range Forecast – Confidence: Medium.
(July 4-9)
A few showers or thunderstorms are possible on the 5th-6th and possibly again around the 9th. Near to above average temperatures on the 4th-5th followed by near average temperatures from the 6th-9th. Note: Computer models remain in poor agreement for next week in regards to temperatures. GFS has rather warm temperatures over most of the Upper Midwest while the EURO is cooler but really just seasonable temperatures instead of the warmth that the GFS is showing.
