March 14, 2015 Weather Report - Record warmth expected in the Northern Plains, Upper Midwest, and the Northland on Sunday, some parts of South Dakota could be in the 80s; Shower potential on Monday

/Issued 7:43 PM CDT, Saturday, March 14, 2015/

850mb temperature forecast for Sunday per 18z NAM/WRF model.  Pretty crazy to see +12 to +14C H85 temps this far north in March, but that is what is predicted for Sunday.  This should lead to widespread 60+ degree high temperatures in the Northland...Only cool spot will be along the North Shore of Lake Superior.  I think Downtown Duluth and Superior will also get fairly warm on Sunday, although there is a chance for a lake breeze especially before Noon.  Source, college of dupage website.

















*RECORD WARMTH POSSIBLE ON SUNDAY*

-The record high temperature for March 15th at Duluth, Minnesota is 60 degrees which was set in 2010.

-The record high temperature for March 15th at International Falls, Minnesota is 57 degrees which was set in 2012.

I think both locations could tie or break their record high temperature on Sunday.
