Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Today's Weather:

High pressure over the Central Great Lakes is maintaining a dry southeasterly flow for Northwest Wisconsin, Eastern and Northeast Minnesota where Afternoon PWS averaged around 1/2".  More moist conditions were found in Northcentral Minnesota Today with PWS of 1.00-1.20".  There has been a few rain showers or sprinkles passing E-NE across Northern Minnesota Today while dry weather continued for the rest of us.  Highs Today were quite similar to Sunday with 70s common in most locations, but the lake breeze has picked up Today which kept coastal communities in the 50s and 60s.  Winds Today were out of the east or southeast at 5-15 mph.

Today's Upper Level Analysis:

500mb troughs covered Eastern Canada and Northeast U.S. with another 500mb trough in the Western U.S., with an upper level low over Central Manitoba Province Canada.  A southwesterly flow aloft was in place across the Upper Midwest Today ahead of the trough and upper low to our west and on the backside of the upper trough out east.  A hot airmass was rebuilding in portions of the Southern Plains Today with latest surface observations showing widespread 90-105 degree temperatures from Central Kansas through Oklahoma, south to Texas and west through parts of New Mexico and Arizona.

Tonight:

Scattered showers will be found in Northcentral through Eastcentral Minnesota and possibly reaching far Northwest Wisconsin Overnight.  Most of the measurable rain Tonight should stay along and west of Highway 53 which means the Arrowhead and most of Northwest Wisconsin will remain dry.  Partly to mostly cloudy skies are forecast Tonight with lows in the 40s and 50s.  Winds will be out of the east or southeast under 15 mph.

Tuesday and Tuesday Night:

High pressure remains centered in the Central Great Lakes with low pressure from the Northern Plains to Central Plains.  Scattered showers are possible Tuesday Morning in Northern-Eastern Minnesota into extreme Northwest Wisconsin, the rest of Tuesday should then be rain-free for all areas.  Some showers could return Tuesday Night mainly west of Highway 53 once again.  Partly to mostly cloudy skies are expected Tomorrow with highs in the 60s and 70s.  Mostly cloudy skies are forecasted Tomorrow Night with lows in the 40s and 50s.  Winds during this period will be out of the east or southeast under 20 mph.

Extended Forecast:

Low pressure along with an upper level trough will finally move into the Upper Midwest for Wednesday before slowly exiting to our east on Thursday.  Showers should become more widespread in our area for Wednesday into early Thursday as this system moves through.  High temperatures for Wednesday and Thursday will mainly be in the 60s with a few spotty 70s also possible, it will be cooler both days near Lake Superior.  Low temperatures for Wednesday Night and Thursday Night will be in the 40s and 50s.
