Another very chilly morning across Texas as the Arctic High Pressure cell settled over the Piney Woods of East Texas overnight and will begin to shift E bringing warmer weather as a Pacific flow dominates the Western and Central United States. Out West, at least two major storm systems will impact California bringing flooding rains at lower elevations and higher elevation snowfall measured by the yardstick.

Attention turns toward the late week timeframe when a strong storm drops SE out of the Gulf of Alaska into California and wraps up into a Winter Storm over New Mexico into the Panhandles of Texas and Oklahoma with both warm and cold sector weather worries for the Lone Star State. In the cold sector, modified Arctic air associated with a cold upper trough and strong High Pressure cell over the Great Lakes extends back SW to the Southern Rockies. Shallow cold air drainage into the Panhandle and possibly portions of N Texas could create a myriad of winter weather worries, mainly in the form of freezing rain and sleet. In the warm sector along and ahead of the organizing Pacific Front, round of heavy rain and possibly thunderstorms may be possible. The storm track on this next weather system is a bit further South than the last one, but is Pacific in nature versus what we experience last Thursday into Friday where its origin was out of Canada. Typically there is a lot of volatility with these Southern tracking Storms leading to some uncertainty in the sensible weather forecast.
