Weather Synopsis

Still seeing an amplified weather pattern with upper lows over the northeast U.S. and southwest U.S. while an upper level ridge breaks down as it moves east into the upper Midwest.  There is a lot of warmth once again today just a little farther east compared to Sunday.  Highs today ranged from the mid to upper 80s in southwest Minnesota with 60s here in the Northland but the exception to this continues to be near Lake Superior with highs only making it into the 40s thanks to the persistent NE wind coming off the Hudson Bay high, that high is also leading to a very dry airmass in our area with late afternoon dew points only in the teens and 20s while a more humid airmass consisting of dew points in the 50s covered parts of southern Minnesota.

*An area of low pressure over southwest Minnesota late this afternoon will drop SE into eastern Iowa by daybreak -- A warm front connected to this low will be over southern Minnesota this evening before it drops south overnight.  There is a corridor of instability with CAPE to around 1000 j/kg along with mid level lapse rates ~7.0 c/km covering much of southern Minnesota with elevated instability with CAPE of 100-300 j/kg extending north into western-southern parts of the Northland late this afternoon.  Scattered showers and a few thunderstorms are expected tonight mainly from north central into east central Minnesota and far western Wisconsin.  Heavy downpours and occasional lightning should be the main hazards out of this activity.  Note:  A few showers could also affect parts of northeast Minnesota and far northwest Wisconsin tonight but with such a dry airmass in place it will be hard for more than a few light showers or sprinkles to reach down to the surface.

*Lows tonight will be in the 30s and 40s with highs Tuesday in the 50s and 60s.

*Not much going on in terms of weather in our area for Tuesday or Wednesday but there will be a cold front that moves south across the Northland Wednesday, and a few spotty showers could develop as that front moves through.
