Day 3 of Des Moines, IA (KDSM)

Very quiet weather expected, with basically no clouds for day 3. Light winds and clear skies will lead to good radiational cooling tonight, and lots of sun will lead to a quick warm up tomorrow, likely above model guidance as is typical for this time of year when there is sun. I’m a bit surprised by how slowly it’s warming up today with sunny skies though, so maybe it won’t overshoot too much tomorrow. The cold air mass is still kind of in place today, but is quickly moving out and getting modified and should not have any influence by daytime tomorrow. Winds will switch to southerly and strengthen during the day tomorrow with daytime heating mixing the stronger winds aloft down to the surface, but they will not be that strong, and USL seems to have a bit of a high bias with wind in this city.
