After temperatures reached 69 degrees Tuesday, many of us are loving this break from winter. However, by Wednesday night, the consequences arrive in the form of thunderstorms that will drop heavy rain and bring the threat of flash flooding.

A few storms may be severe and produce damaging winds. A Flash Flood Watch has been issued for the D.C. area starting at 3 p.m. A strong cold front has been triggering severe storms all morning from the Great Lakes to the Gulf Coast.  Here's a look at the damage reports from this system in the past 24 hours:  



The Storm Prediction Center has put the entire area under a slight risk category for severe weather, primarily damaging winds in excess of 60 mph.
The front will reach western Virginia and northern Maryland by mid-afternoon.  We could see some spotty showers in D.C. at that time, but the main event will be later tonight when the cold front arrives. The most likely time of showers and storms is between 9 p.m. and 2 a.m.
Here is a look at our in-house computer model forecast, showing the heavy rain with thunderstorms at 11 p.m. tonight:  


The morning run of the NAM model is in close sync with this and shows the squall on top of us around 1 a.m.   


While the brunt of the worst weather will be short-lived, the rain will be heavy during the thunderstorms. Around an inch can be expected in a short period of time, causing flash flooding in low lying areas and in urban areas.


Use caution on the roads tonight. The moisture will cut off pretty quickly after the front passes, and it will be windy and colder Thursday. Some sunshine by the afternoon with a high in the mid 40s. Back into the 30s for highs on Friday.
