Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Strong high pressure of 1024 mb has moved into Southern Wisconsin-Northern Illinois late Today but it’s ridge extends north-west into Central Minnesota. Mostly sunny-sunny skies prevailed across our area Today with a somewhat milder day compared to Sunday…Highs Today were in the middle 60s to lower 70s with 4 PM 850 mb temperatures of +7 to +9 degrees C. Dewpoints This Afternoon were running in the 40s to around 50 degrees with PWS right around one half inch once again. Winds Today were out of the south, west, or north under 15 mph.
(Today’s Upper Level Analysis)
Jet stream winds have relaxed to more normal late Summer levels Today and have really diminished compared to just a few days ago. An upper level low (576 meters) was drifting east through Southwestern Montana This Afternoon while an H5 trough covered Eastern Canada-Northeast U.S. Northwesterly flow aloft was found over the Upper Midwest Today on this final day of August 2009. H5 ridging (588 meters) was confined to the Southwest U.S. and adjacent portions of Western-Central Texas Today.
High pressure will be centered to our southeast which will result in mainly clear skies along with a threat for some patchy late night fog. Lows will be in the 40s to around 50 degrees but colder 30s will occur in the traditional cold spots. Winds Tonight will be out of the south, west, or north under 12 mph.
(Tuesday and Tuesday Night)
High pressure remains in control of our weather as it stays put to our southeast. Look for mostly sunny-sunny skies on Tuesday with clear-partly cloudy skies Tuesday Night. May see some early Morning and late night fog patches around our area. Highs Tuesday will be in the 68-75 degree range with lows Tuesday Night in the 40s to lower 50s. Look for south winds under 15 mph during this period.
High pressure should remain in control of our weather from mid to late week as it remains to our south-east. The disturbance moving into the Northern Rockies Today is forecast to drop south-east and should remain far enough to our southwest to prevent any showers from reaching our local area later this week. Will still have to monitor a cold front which is expected to drop south out of Northern Canada during the Thursday-Friday time period…however right now it appears that this boundary will not make it south of the border. All in all it looks like it will be mainly dry across Northeast Minnesota and Northwest Wisconsin from Wednesday through Friday with just an outside risk for a passing shower later this week from the cold front to our north. Highs Wednesday and Thursday will be mainly in the 70s with lows both nights generally in the 50s. Looking ahead into the Labor Day holiday weekend features more of the same weather with pleasant temps and no rain until perhaps early next week. Temperatures may turn cooler however near Lake Superior later this week or this weekend as we could see an easterly component to the wind start to develop during that time.
