by WeatherOps, on Dec 17, 2014 4:01:43 PM

Snow falling across the Northeast will begin to taper off on Thursday. Thunderstorms will develop in the afternoon or evening for portions of Texas. Moderate to heavy rainfall is likely across the South Central Plains, Coastal rainfall and mountain snow will be likely for portions of the Cascades.

Northeast: Periods of snow will continue across northern Maine on Thursday as a low pressure area lifts northeastward into the Canadian Maritimes. Snowfall should taper off by the evening hours, but an additional 2-6 inches will be possible.

Texas: A fairly potent upper level disturbance is forecast to move across northern Mexico on Thursday, with thunderstorms developing over the Big Bend area by late afternoon or early evening and spreading eastward across portions of southern and central Texas. A few strong or severe storms will be possible, with moderate to large hail and damaging winds the main threat.

South-Central: The same upper level disturbance above will also help to induce a surface low pressure area over southern Texas, which will allow moisture from the Gulf of Mexico to increase over central/southeast Texas eastward into Louisiana. Meanwhile a weak cold front will drop southward across the Southern Plains. The combination of these weather features will allow for the development of scattered to numerous showers and perhaps a few thunderstorms across the region, especially by the evening hours. Rainfall amounts should average between 0.50 and 1.50 inches, with areas of locally heavy rainfall possible.

Pacific Northwest: The next storm system will begin to affect the Pacific Northwest on Thursday as a cold front associated with a strong low pressure area moving into the Gulf of Alaska approaches from the west. Rain and showers will begin to increase in coverage during the afternoon and evening hours, with rainfall amounts of 0.50 to 1.50 inches expected for coastal areas. The same cold front bringing rain to the coastal Pacific Northwest will also allow for snow to begin across the Cascade Mountains. Snowfall amounts on Thursday should initially be light, probably 2-4 inches for elevations above 6000 feet.
