Words that apply to this Tuesday: tiresome, teary, tempestuous, too bad. In a lame turn of events, nature is scrubbing over the warm blessedness of the past few days with a sopping dishrag of rainy, gray weather.

The chance of rain in D.C. on Tuesday is 100 percent. The start of the dripping is likely to sync up with the morning commute. It could be worse, though. A long section of the U.S., from Mississippi to Georgia up to the Great Lakes, is looking at the possibility of several inches of snow accumulating by late today. The Deep South could get a rare 2 to 4 inches of snow, while eastern Michigan and northern Indiana are flirting with 5 to 8 inches. That's because a system with a heart of pure cold has become lost from the guiding circulation of the jet stream, and is drifting aimlessly northward bleeding precipitation onto everything in its path. You can watch it meander over the country in this animated forecast from NOAA's Hydrometeorological Prediction Center.

The skin will tauten at a drop in temperatures over the coming week. While Tuesday will only be in the lower 60s during the afternoon, it's probably the fabulous 50s afterward until the weekend. However, at least Wednesday and beyond look less drizzly. Check the extended ABC7 forecast for details. A spot of good news (or bad, if you love winter weather): In-house senior meteorologist Bob Ryan says that there's no indication of any extremely cold air or snow in the immediate future.

This eye-in-the-sky image was posted onto Facebook by the National Weather Service of Baltimore/Washington. The NWS says:

A rainy day is expected [Tuesday] with showers beginning in the morning and continuing into the afternoon for the Baltimore/Washington area. A low pressure system, currently located in the Tennessee Valley, will push an occluded front across the region. This image (a combination of visible and infrared satellite imagery plus HPC surface analysis) shows the location of the low pressure system and fronts. The reddish colored areas are higher clouds and generally associated with precipitation.
