Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Today’s Weather:
Low pressure of 1008mb was located near Chicago, Illinois late This Afternoon. Rain associated with this low continued to affect portions of Northwest Wisconsin Today, mainly east of a line from Webster to Bayfield. High temperatures due to the clouds and areas of rain in Northwest Wisconsin were in the middle 50s to lower 60s. Partly cloudy to sunny skies prevailed in Northern Minnesota with warm temperatures for late September…Highs ranged from the middle 60s around the head of Lake Superior to the 70s from the Brainerd Lakes to Iron Range and Arrowhead regions, a few locales even came close to reaching 80 degrees This Afternoon in Northern Minnesota. Winds Today were out of the west, north or east under 15 mph.
Today’s Upper Level Analysis:
500mb low was centered over Southern Lake Michigan late Today per water vapor satellite imagery. NE upper level flow continued in the Upper Midwest Today on the backside of this system.
Tonight:
Surface and upper level low will continue sit and spin near Chicago, Illinois. Areas of rain showers will persist during the Evening in Northwest Wisconsin, then dry weather should return to these areas Overnight. Mostly cloudy skies will continue in Northwest Wisconsin with clear to partly cloudy skies for Northern Minnesota. Lows will be in the 40s and 50s with some 30s possible in Northern Minnesota. Winds will be out of the west, north or east under 15 mph. Note: Patchy fog could develop late Tonight, any fog that does form will burn off between 7-9AM Wednesday.
Wednesday and Wednesday Night:
Low pressure will finally pull slightly more to the northeast during this period thanks to an approaching cold front which is forecasted to move southeast across Northern Minnesota and Northwest Wisconsin Wednesday Night. Warm air will be found ahead of this front as 850mb temperatures climb to +12 to +18 degrees C on Wednesday, this should lead to high temperatures reaching the 70s and lower 80s in Northern Minnesota with 60s and 70s for Northwestern Wisconsin. Lows Wednesday Night will be 40s and 50s. Winds Tomorrow will be out of the southwest, north or east under 15 mph. Winds will increase Tomorrow Night as they become northwest at 10-25 mph with gusts to 30 mph late in the night. Partly to mostly cloudy skies are expected during this period with the potential for a few showers by Tomorrow Night.
Extended Forecast:
A potent upper level trough and area of low pressure will dig south/east into the Great Lakes on Thursday before moving off to our east Thursday Night and Friday. Gusty northwest winds will continue on Thursday with wind speeds of 15-35 mph, cold air advection will be occurring as well with 850mb temperatures falling to zero to +4 degrees C. Even colder air arrives by Friday with 850mb temperatures forecasted to drop to zero to -4 degrees C. Expect some rain showers for Thursday with mainly dry weather from Thursday Night into Friday Night as high pressure settles into the Upper Midwest. High temperatures on Thursday will be in the 50s and 60s with lows Thursday Night in the 30s and 40s. Highs on Friday will be in the 40s and 50s with lows Friday Night in the 20s and 30s.
Long range model guidance is showing a pattern change for next week with a SW 500mb flow developing across the Plains. This with time could lead to wetter weather for portions of the Northern Plains and Upper Midwest, in fact there might even be some early October thunderstorms at some point next week.
