Waves of showers have deposited just over half an inch of rain for most of the immediate D.C. area and there’s more coming.  However, the general trend will be for decreasing coverage and intensity of showers as Wednesday progresses.

Through Tonight: Intermittent showers are likely with brief downpours.  A rumble of thunder is possible, mainly in our southern suburbs.  In between showers, we’ll have some rain-free periods, but it’s damp more often than not.  At least it’s not cold, with overnight lows ranging from the mid-to-upper 50s.  Rainfall amounts are variable depending on where local downpours develop ranging from 0.25-0.75 inches by and large.

Tomorrow (Wednesday): It’s mostly cloudy, but showers are a bit more scattered and less frequent than today, and some longer dry intervals are possible.  I can’t even rule out some periodic brightening of the skies boosting temperatures close to 70 degrees for a high.  Winds are from the east and then from the south, around 5-10 mph.
