PM Update: Showers tonight and Tuesday, with plenty more after that

Flash flood watch Tuesday evening through Wednesday night for entire region *

Rain moved into the D.C. metro region between 3 and 4 p.m. this afternoon and it’s here to stay for a while.  Showery waves cycle through the region tonight and Tuesday while the potential for heavy rain may hold off until Tuesday night and Wednesday.

Through Tonight: Intermittent rain showers are a guarantee, though they may decrease in coverage and intensity late at night and towards morning.  Temperatures slide back just a few degrees, with lows around 50.  Winds are from the east around 10 mph.

Tomorrow (Tuesday): More intermittent rain showers, which may pick up a bit towards the late afternoon and evening hours.  Morning rain showers may be lighter and more scattered.  A steady wind from the east (15-20 mph, with some higher gusts) puts a brake on temperatures, with highs only in the mid-50s.  Rainfall totals through Tuesday evening aren’t all that impressive…probably around 0.25-0.5″.  The potential for heavier rain comes overnight Tuesday into early Thursday morning.
