Beautiful Day, Increasing Clouds Overnight

Despite a weak pressure gradient keeping wind speeds up through the night, temperatures are generally running in the upper 50s to near 60 this morning. Northwesterly flow aloft and northeasterly flow at the surface will make for another pleasant day with abundant sunshine and low humidity. A few patchy afternoon cumulus will prevent full sunshine, but these will have little impact on the sensible weather. Highs this afternoon should top out around 83. Tonight's forecast is a little tricky as an upper level disturbance embedded within the northwest flow will approach the area. Model guidance really ramps up the lower level and mid-level moisture in advance of this feature, and in fact, some models are indicating the chance for light showers overnight. With northeasterly winds overnight, I'm not completely buying the fact that low-level moisture increases as much as the models suggest. With the deepest moisture staying to our east, I think this will also be where the best chance for rain will be. However, I can't completely rule out the chance of an isolated shower overnight. Increasing cloudiness will begin by this evening and thicken overnight, which should keep lows around 64 tomorrow morning.
