A fresh south and southwest flow out ahead of a cold front has brought us mild conditions today, with highs largely reaching into the mid-and-upper 70s across the area. Steadily increasing and lowering clouds point to changing weather though. Fortunately for sunshine fans, any rain that falls this evening into tonight will be out of here for tomorrow.

Through Tonight: Clouds keep increasing into evening as a cold front approaches from the west. Showers and thundershowers should begin pushing into the area by about 6-8 p.m.  Although the first band may favor areas to the northwest and north, more showers are behind it. Brief moderate to heavy rain along with some gusty winds and lightning are possible with any activity before the front passes. Showers should wind down in the hours around midnight, eventually leaving clearing skies in the front’s wake. Lows range from the low 40s in the north and west suburbs to the upper 40s in the warm spots like D.C. and further southeast.

Tomorrow (Thursday): The cold front is out of here, leaving behind mainly clear skies in its wake. Thursday is cooler than today, but hard to complain about high temps in the low-to-mid 60s with lots of sun and not a lot of wind.
