PM Update: Mild through Wednesday with increasing clouds, slight shower chance

What a spectacular day it was - a far cry from the violent weather around Dallas! High temperatures reached into the low 70s after scattered morning frost in our colder suburbs. No frost tonight with warm southerly flow and an incoming blanket of clouds. Very mild Wednesday, but look for lots of clouds and the slim chance of a shower.

Through Tonight: Clouds gradually lower and thicken, transitioning from partly cloudy to mostly cloudy. There may be enough breaks to see Venus invade the Pleiades in a rare sunset conjunction. Look west (sky map). Overnight lows are mild, ranging from the upper 40s to mid-50s (suburbs to city).

Wednesday: Skies are mostly cloudy, though there may be an interval or two of sunshine. During the afternoon, with a weak cold front around - a shower or thunderstorm could pop - but more likely in central and southern Virginia. The airmass ahead of the front is mild, allowing highs to reach the low-to-mid 70s.
