One, two punch

This holiday weekend is shaping up to see two rounds of weather as two low pressure centers track over Minnesota during the day on Thursday and then again on Friday. The two storm tracks are plotted below.

lowtrack_circlesThe first round will be a rain event as temperatures will be well above freezing (temperature projected to be above the freezing mark, the green line, in the chart below) during the day on Thursday before dipping below the 32 degree mark late Thursday night into Friday. This will force the change over from rain to snow.


Rain totals for Thursday range from two tenths to four tenths. This will create slick roads during the overnight hours into Friday.


As far as snow goes on Friday, we could see a few inches of snow out of the second system as it moves in, but nothing major. It will be the rain freezing over that will create the greatest problems.


Welcome to the world of everything!
