Cloudy, Mild, & Breezy

This past weekend is what I call perfect weather with cool nights and mild afternoons. The first part of the work week will continue to be pleasant, but big changes are in store for most of the week. We're currently starting off the day with temperatures in the lower 50s, but cloud cover associated with a passing upper air disturbance has moved into the area and will likely continue for much of the day. Despite the mostly cloudy skies, most locations should still be able to manage to top out near 70 again this afternoon. In fact, I'll forecast an afternoon high of 70. If there is a little more sunshine than I expect, temperatures will likely be a couple of degrees warmer. Additionally, stronger boundary layer winds and an increasing pressure gradient will allow winds to be breezy this afternoon.

By this evening, a warm front to our southwest will gradually lift northward in response to a strong low pressure center that will be moving across the Central Plains. Moisture will increase at the surface and aloft and this will keep skies mostly cloudy overnight. With southerly winds remaining constant, I'll shoot above guidance and forecast a low of 56 tomorrow morning.
