/Issued 7:31 PM CDT, Thursday, June 25, 2015/
Radar image from 7:32 PM CDT this evening. Scattered showers and thunderstorms continue in parts of Northern and Northeast Minnesota early this evening, this activity is moving toward the south and should weaken during the next few hours. Note: I think the Twin Ports remain dry tonight as the showers currently to our north and northeast should dissipate before moving into the city.

Weather Summary for Northeast Minnesota and Northwest Wisconsin
Date: June 25, 2015
High pressure covered the Upper Midwest today but lingering moisture, warming from the sun, and colder temperatures aloft led to the development of a few showers and thunderstorms in far Northern Minnesota and also over the Arrowhead of Minnesota. A lake breeze boundary probably helped to trigger today’s storm in the Arrowhead. There is some instability in place with CAPE of up to 1000 j/kg this afternoon and lifted indices ranging from -2 to -4C. Otherwise the Northland saw a mix of sun/clouds today with high temperatures in the 70s to around 80 degrees with cooler temperatures near Lake Superior. Winds were generally variable in direction at around 5 to 15 mph.
Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Short Term Forecast – Confidence: High.
Tonight (June 25)
Partly to mostly cloudy skies are expected Tonight with widely scattered showers and thunderstorms coming to an end later in the night. A few of the storms could be on the strong side with torrential rain, hail, gusty winds, and lightning but again the coverage of the storms will be isolated to widely scattered. Low temperatures will be in the 50s to lower 60s but 40s are possible in some locales. Winds will be light and variable in direction at around 10 mph. Note: Areas of fog could develop Tonight especially near Lake Superior.
Friday and Friday Night (June 26)
High pressure will remain in control of our weather but much like Today will likely see a few spotty showers and thunderstorms develop during the Afternoon and Evening hours thanks to daytime heating, some cold air aloft, and a bit of instability and moisture which will be over the Northland. Also like Today the convection should tend to stay away from Lake Superior. Partly to mostly cloudy skies are forecast this period with areas of fog especially early in the day. High temperatures will be in the 70s and lower 80s with cooler temperatures near Lake Superior. Lows Friday Night will be in the 50s to lower 60s. Winds will be out of the south, north, or east at 5 to 15 mph.
Extended Forecast – Confidence: High.
Saturday through Monday (June 27-29)
An area of low pressure along with a cold front and upper level trough will be digging into the Upper Midwest this weekend. Scattered showers and thunderstorms are possible in the Northland from Saturday Afternoon through Sunday as this system moves through. There should be enough instability that builds-up to produce a few strong storms this weekend. A few lingering showers or thunderstorms are possible on Monday as this system pulls off to the south/east.
High temperatures on Saturday are forecast to be in the 70s and 80s with lows Saturday Night in the 50s and 60s. Highs on Sunday will be in the 70s to around 80 with lows Sunday Night in the 50s to lower 60s. Highs on Monday will be in the 70s. Note: It will be cooler near Lake Superior on Saturday and Sunday.
Long Range Forecast – Confidence: Medium.
(June 30-July 5)
A few showers or thunderstorms are possible from time to time between the 1st-4th of July. Not looking at all day rains but the potential is there for a few showers or storms during the aforementioned time frame. Near to below average temperatures are expected from June 30-July 5 but again as I mentioned in the past few posts there is a chance for above average temperatures on one or two days during the long range.
