Weather Synopsis

A very cool airmass was over the Northland today.  Late afternoon 850mb temperatures were down to +4C as cold air advection continued in our area today on the west/southwest side of a large upper level low pressure system which covered the Great Lakes and central Canada.  Mostly cloudy skies were common today with lingering showers and drizzle moving southeast across the area.  Highs today were only in the upper 40s to middle 50s, well below average for May 30th.

Note:  Rainfall totals since Monday have ranged from as little as a trace to as much as 0.25 inches over northeast Minnesota and northwest Wisconsin.

One more night of mostly cloudy skies along with some drizzle and rain showers as the upper level low that has been affecting us since this past weekend continues to do so tonight.  Lows will be in the 40s with 30s possible in far northern Minnesota if skies clear out enough during the night.

A change in the weather takes place Wednesday and Thursday as high pressure builds in which should result in mostly sunny skies in our area for both Wednesday and Thursday.  Warmer temperatures will also occur with highs both days in the 60s and 70s (The warmer day being Thursday) These high temperatures are normal to slightly above the average for the final day of May and first day of June.

Another change in the weather is possible this weekend as low pressure moves east or southeast out of the northern Plains -- This system could bring some rain to northeast Minnesota and northwest Wisconsin Saturday and Sunday along with cooler temperatures and a gusty east wind near Lake Superior.  Note:  There are differences in the computer models in regards to the track of the system this weekend, and the timing of it.  Sunday could end up being the drier day of the two but I wouldn't bet the farm on that just yet.
