Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Low pressure of 1000mb has moved into Northern LOWER Michigan early This Evening. Clouds and patchy drizzle/light rain continued on the backside of this low across Northeast-Eastern Minnesota through Northwest Wisconsin while a mix of clouds/sun were occurring farther west. High temperatures Today were in the middle 60s to lower 70s from International Falls to the Brainerd Lakes area with 50s to lower 60s elsewhere. Winds Today were out of the north or northeast under 20 mph.
Today's Upper Level Analysis:
500mb low and trough covered the Great Lakes, Central and portions of Eastern Canada per RUC model analysis and water vapor satellite imagery. Upper level ridge covered the Southwest U.S. with an upper level trough in place over the Pacific Northwest.
Low pressure will move into Eastern Ontario Province while high pressure moves east from the Northern Plains to Upper Midwest. Partly-mostly cloudy skies will be found in our area with patchy light rain and drizzle in Northwest Wisconsin and Arrowhead of Minnesota, this precipitation should end around Midnight. Lows Tonight will be in the 40s and 50s with north or west winds under 15 mph.
Friday and Friday Night:
Temperatures will warm up during this period as high pressure moves overhead. Should see at least some sunshine on Friday with high temperatures reaching the 70s in most locales which is about normal for late June. Clear-partly cloudy skies are expected Tomorrow Night with lows in the 40s and 50s. Winds during this period will be variable or west-southwest in direction under 15 mph.
Dry weather should carry over into Saturday with partly to mostly cloudy skies. Highs will be in the 60s and 70s with lows mainly in the 50s. A cold front moves east out of the Northern Plains Sunday and Monday with increasing moisture and instability moving into the Upper Midwest out ahead of that boundary. Showers or thunderstorms are possible in Northern Minnesota and Northwest Wisconsin late this weekend into early next week. Too early to tell if any severe weather will occur with this front, low level jet looks very weak, but winds in the mid/upper levels of the atmosphere will be quite strong and the 6KM and EFFECTIVE BULK SHEAR are forecasted to be favorable for storm development Sunday Afternoon/Night per latest SREF model run (15z). High temperatures on Sunday will be in the 60s and 70s with lows Sunday Night mainly in the 50s.
Dry weather returns for next Tuesday and Wednesday, June 28th-29th. Then, a vigorous storm looks to pass well to our northwest by late next week with gusty southerly winds and an area of very warm temperatures pushing N-NE into the area sometime between Wednesday-Friday, June 29th-July 1st. High temperatures could soar well into the 80s, perhaps even some 90s especially for next Thursday and Friday. Not sure yet if this warm air will make it to the lakeshore, that will depend on the wind direction, and that's still uncertain this far out in time.
