TYLER, TX (KLTV) - A strong storm system will develop across the northern Gulf this weekend bringing some much needed rain to East Texas. Precipitation forecast show much of the area could receive between one and two inches between Saturday night and Monday morning(see here). At the same time this surface low is developing across the northern Gulf, and upper level low pressure will be moving into our northern counties. It is this upper level low that will provide enough cold air in the mid and upper levels for snow to develop. Right now it looks as though temperatures Sunday afternoon and evening will be in the middle 30s from I-20 north. Although this is above freezing, it is cold enough for snow to reach the surface. Based on the forecast intensity of the precipitation, it does appear some areas of East Texas could see accumulations of snow Sunday afternoon and evening. The best chance of seeing accumulating snow is over our northeastern counties, mainly along and north of a Sulphur Springs to Jefferson line. Here 2 to 4 inches of snow with locally heavier amounts could occur.
Longview and Jacksonville areas, it appears we will mostly see a rain/sleet/snow event at times late Sunday. Right now...accumulations of 1 to 2 inches are now forecast for the central region of ETX. In the Lufkin, Nacogdoches and Crockett areas mainly a cold rain is expected with a few pockets of sleep possible. If the low pressure tracks farther south, then a mix of sleet and snow could occur. As with all winter forecast in Texas, a lot could change between now and Sunday. If the low track farther south, much of East Texas could see an accumulating snow event. If the low tracks farther north, all areas of East Texas would probably just receive rain.
Once Sunday's storm system moves out, much colder air will move into the area. Highs by Tuesday and Wednesday still only appear to be in the 30s. A fast moving disturbance could even produce a few flurries during the mid week period but no travel problems are anticipated with this system. Please stay tuned to the latest weather information on this developing winter storm.
