DC Area Forecast: Smooth sailing until Thanksgiving Day, then chance of rain returns
While most pre-Thanksgiving travel should go smoothly, a pair of storm systems could make things difficult in the southern and eastern United States Thursday through Sunday.
In the west, the weather appears generally calm, though Portland and Seattle may see rain — part of the same system that can bring snow to higher elevations.
We’ll outline what to expect in our city-by-city travel forecast.
Ahead of a cold front sweeping east on Wednesday, moisture from the Gulf of Mexico will move north. This will lead to showers and downpours on Thursday, spreading from eastern Texas in the morning and eventually to Arkansas, southern Missouri and Louisiana. Evening showers can creep into Mississippi and West Tennessee.
Moisture streaming north along the front on Thursday evening will bring rain showers to the Ohio Valley, with heavier showers over the south. By Friday, a patchy band of rain will stretch from the Carolinas into Quebec, with light showers along the Interstate 95 corridor in the Mid-Atlantic and New England.
All told, a general 2-3 inches is likely in eastern Texas, with about a half-inch to an inch over most of the south except for the Florida peninsula. A broad tenth to quarter inch will fall as light showers work over the Ohio and Tennessee valleys, with similar amounts in New England. South Carolina could see up to a third of an inch.
On Friday, a storm system will develop over eastern Texas that will track into the Red River and southeastern Oklahoma on Saturday. Ahead of the storm system, warm, moist Gulf air will flow northward. This will allow rain to fall over much of central and eastern Texas on Friday immediately after System 1.
Behind the center of the system, northerly winds will draw in cold air from the north; moisture wrapping in the storm and rising and over this cold air will fall as snow. This could drop tillable snow in parts of the Texas Panhandle and Hill Country on Friday. A winter storm watch is in effect.
This system will then bring rain to the lower Mississippi Valley on Saturday, then to the Ohio Valley, Midwest, Mid-Atlantic and Northeast on Sunday.
