Today’s Weather Summary for Northeast Minnesota and Northwest Wisconsin
Partly to mostly sunny skies were found in our area Today with highs getting back into the 60s which is a few degrees below to around seasonal levels as we close out the end of May.  High pressure ridge of 1018-1020mb remained in control of our weather Today as it sits over the Upper Midwest.  Winds were variable at 5 to 15 mph.
Today’s Upper Level Analysis:
An upper level trough with up to 60 meter per 12 hour height falls covered the Upper Midwest and Central/Northern Great Lakes per water vapor satellite imagery and RUC model analysis.  850mb temperatures as of 3pm ranged from +2 to +4C in Southern Minnesota to +6 to +8C in Northern Minnesota.
-2km visible satellite image of the Northern Plains and Upper Midwest from This Afternoon.  Note:  The absence of clouds close to Lake Superior as a light lake breeze developed Today resulting in a stable atmosphere.












Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Tonight (May 31st)
Clear to partly cloudy skies will occur with light winds under 10 mph.  Another chilly night ahead as lows drop into the 30s and lower 40s with 20s possible away from Lake Superior.  Areas of frost will develop once again Overnight.
-Tonight’s low temperature forecast.










-Tonight’s frost/freeze potential.













Friday and Friday Night (June 1st)
Partly to mostly sunny skies are expected on Friday.  There could be a few Afternoon/Evening showers that develop in Western parts of our area, from International Falls and Walker, south to Brainerd and Aitkin.  It should remain dry in Northeast Minnesota and Northwest Wisconsin.  Highs Tomorrow will be in the 60s to around 70 degrees with southwest or northeast winds at 5 to 15 mph.  For Friday Night, expect a partly to mostly cloudy sky with lows mainly in the 40s, winds will be out of the west or northwest at 5 to 15 mph.
-Friday’s high temperature forecast.










-4km Hi-Res NAM from Today.  This is valid for late Friday Afternoon.  Could be a few spotty rain showers late Tomorrow PM in Minnesota, west of the Twin Ports.
















Extended Forecast, Saturday-Monday (June 2nd-4th)
A west-northwest flow will cover the Upper Midwest during this period as an upper level low lifts slowly N/NE across the Eastern Great Lakes and Eastern Canada.  A small chance for a shower does exist on Saturday with high temperatures in the 60s and 70s, lows will be in the 40s and 50s.  Sunday and Monday look generally dry at this time, but a disturbance dropping southeast out of the Northern Plains could lead to a few showers/thunderstorms late this weekend and early next week, however, it remains to be seen just how far north/east the better moisture and instability can make it.  High temperatures will remain in the 60s and 70s for Sunday and Monday with lows Sunday Night in the 40s and 50s.
Long Range Forecast (June 5th-11th)
Upper level pattern continues to look fairly amplified/blocky for most of next week, although there are some trends showing up for a possible pattern shift beginning next weekend.  As long as we sit under the upper level ridge we should be dry with any showers/thunderstorms staying over the Rockies and Northern Plains. Showers or thunderstorms may head east into the Upper Midwest sometime during the June 8-11 time frame.  Temperatures are forecast to be near to above average through this period.
-GFS upper level forecast for next Tuesday, June 5th.  Still looks like an amplified configuration with troughs in the Northwest and Northeast U.S. and upper level ridging over the Plains.

Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Tonight (May 30th)
High pressure will be in control of our weather resulting in partly to mostly cloudy skies.  The disturbance across the Northern Plains will stay well to our west/south Tonight, rain associated with that feature will stay in Southern parts of Minnesota.  Lows Tonight will be in the 30s and 40s with light winds.  Patchy frost is possible away from Lake Superior Overnight.
-Tonight’s low temperature forecast.










Thursday and Thursday (May 31st)
The final day of May will be fairly pleasant in our area with partly to mostly cloudy skies.  Temperatures should warm a bit with highs mainly in the 60s with lows in the 30s and 40s.  Winds will be out of the west, southwest or north at 5 to 15 mph.
-Thursday’s high temperature forecast.











Extended Forecast, Friday-Sunday (June 1st-3rd)
A northwest flow will occur for Friday and Saturday.  Can’t rule out a few showers, especially on Saturday. But, for the most part this period looks dry.  High temperatures from Friday-Sunday will be in the 60s and 70s with lows Friday Night and Saturday Night in the 40s to lower 50s.
Long Range Forecast (June 4th-10th)
Upper level pattern is forecast to become rather amplified during this period.  Deep upper troughs are forecast to cover the Western U.S. and Northeast U.S. with an upper level ridge across the Plains.  This will be a slow moving type of pattern, so once it develops it probably will not change for several days.  There is a small chance for showers/thunderstorms next Monday (4th) otherwise it looks generally dry through the 10th.  Temperatures will be near to slightly above normal.
-HPC’s 500mb forecast for next Wednesday, June 6th, 2012.  A highly amplified pattern for the U.S. Troughs over the Northeast U.S. and Western U.S. and a nice ridge for the Plains.  Should the pattern develop like what is shown here, then a period of dry weather should occur across Minnesota for most of next week.
