I woke up a bit late to see if the clouds that moved in grew slowly or if they were here to begin the day. The winds definitely changed throughout the day starting off calm then as a rain cloud moved through they picked up and now it's a calm night with a few clouds blocking the stars. Today was the first really humid day of the year and I can't wait for more of them....... To figure out why the rain passed through today let's take a look at the wind map below.

The circling winds centered over Ohio right now passed through southern Wisconsin earlier today. The Eastern winds on the north side of the low pressure were bringing with them moisture from the Atlantic Ocean. This moisture allowed for clouds to form then for rain to precipitate down helping to melt some of the snow. For tomorrow expect similar warm temps and low pressure. There shouldn't be any precipitation but don't be surprised if we get another light sprinkling like we did today.
