FORECAST IN DETAIL

As if we hadn't had enough rain this fall, we're likely to get dumped on again this week. Today, we're only talking a relatively short period of showers. But after a brief break from the rain tomorrow, a super wet storm system promises to drench us Wednesday into early Thursday. Then, the wind and the cold arrive. No signs of our first snow threat though.

Today (Monday): A cold front along with its clouds and rain put an end to the lovely sunny weather we experienced over the weekend. Cloudy skies will rule the day with a good chance of showers from mid-morning through late afternoon. Rainfall amounts should be around 0.25". High will be in the low-to-mid 50s. Confidence: Medium-High

Tonight: The rain will most likely end by evening, with gradual clearing overnight. A wind from the northwest (at 10-15 mph) will bring in cooler air, dropping lows to near freezing in the colder suburbs to the mid-30s downtown. Confidence: Medium-High

Keep reading for the forecast through the work week...

Tomorrow (Tuesday): High pressure pays a short visit tomorrow, giving us ample sunshine. Temperatures should reach the low 50s. Winds will be from the west at around 10 mph. Confidence: Medium-High

Tomorrow Night: A mostly clear, calm, and cold night before the approach of Wednesday's storm. Lows will range from the upper 20s in the colder suburbs to the mid-30s downtown. Confidence: Medium-High

A LOOK AHEAD

Clouds will rapidly increase Wednesday as a storm developing to the south gathers steam and heads northward. Rain is possible by afternoon, with highs near 50. Rain is pretty close to a sure thing Wednesday night, and it could be heavy at times. Lows will likely be in the mid-40s. Confidence: Medium_High

Rain should gradually diminish during the day Thursday as it turns quite blustery. Temperatures should be steady in the mid-to-upper 40s. Variably cloudy, windy and quite cold Thursday night, with lows in the upper 20s and low 30s. Confidence: Medium

Despite not much in the way of clouds (until late Sunday), the coldest conditions of the season so far arrive Friday and hold on right through the weekend. Highs each day should range from 40-45 with lows in the 20s to near 30. It may be on the breezy side Friday, but winds will diminish over the weekend as high pressure settles in. Confidence: Medium

It does seem as if there has been a lot of rain this fall. Isn't this season normally dry around DC? Or drier than the others? How does Fall 2009 measure up so far rainwise?

I have received about 4.6" of rain so far this month (not including today) and about 52" for the year. I believe the average for the year in this area is about 39" How much rain likely will fall in the Wed./Thurs. period?
