Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Tonight (July 31st)
We will see a warm/moist advection pattern spread into our area Tonight along with a southwest low level jet of 30-40 knots as low pressure and it's warm front and cold front track east across the Northern Plains. Scattered showers or thunderstorms could develop at times, especially in Northcentral Minnesota. There doesn't appear to be a real big severe weather threat for Tonight, but some downpours and lightning could accompany a few of the storms. Lows will be in the 50s and 60s with south or east winds at 10 to 15 mph.
-18z 7.31.12 NAM-HIRES model is hinting at a potential thunderstorm complex in the Northern half of Minnesota late Tonight into Wednesday Morning.
-Tonight's low temperature forecast
An area of low pressure with it's warm front and cold front will be moving through the Northland during this period. Scattered Morning showers or thunderstorms are possible in our area, then will probably get a break before we could see a few more showers and thunderstorms later in the Afternoon and into the Evening hours. There looks to be 2 main spots where storms may fire late Tomorrow PM. One will be along the Minnesota-Ontario border, into the Arrowhead. The other in Eastcentral Minnesota and Northwest Wisconsin.
Warmer air aloft may keep many thunderstorms from developing Tomorrow Afternoon, but any storm that does develop and can sustain itself could become severe with strong mid-upper level winds in place along with decent amounts of instability, moisture, and wind shear.
Partly to mostly cloudy skies are forecast this period with highs Tomorrow in the 80s and lower 90s with lows Tomorrow Night in the 50s and 60s. Winds will be out of the south, east, or northwest at 10 to 20 mph.
-Wednesday's high temperature forecast
-A 5% chance for severe thunderstorms continues in all of Northeast Minnesota and Northwest Wisconsin for Wednesday. (Storm Prediction Center)
Extended Forecast, Thursday through Saturday (August 2nd-4th)
Thursday: A cold front will settle south and out of our area with high pressure to our north. Looks mainly dry in our area with highs in the 70s and 80s. Lows will be in the 50s and 60s.
Friday: Low pressure approaches from the west with another warm front and cold front heading into the Upper Midwest. The chance for showers and thunderstorms will increase in Northeast Minnesota and Northwest Wisconsin as this system approaches. Still too early to tell if will have a severe threat, but it's certainly possible since this system looks pretty strong and should have fast winds aloft and decent shear to work with. Stay tuned! Highs on Friday will be in the 70s and 80s with lows in the 50s and 60s.
Saturday: Low pressure will pass north of our area with a cold front exiting to our south/east. Showers are possible on Saturday with a few thunderstorms also possible, especially in Northwest Wisconsin. Highs will be in the 70s to lower 80s.
-5 day rainfall forecast from the HPC. Valid through Sunday, August 5th, 2012. Seeing some decent rainfall totals across Minnesota, some of this will fall Tonight-Wednesday, the other event looks to be Friday-Saturday.
Long Range Forecast (August 5th-10th)
Dry weather is forecast for Sunday (5th) Could see quite a warm/heat wave spread into the Northern Plains and Upper Midwest for the early/mid part of next week (6th-8th) The potential also exists for a few showers or thunderstorms from the 6th-10th.
