The leading edge of a powerful and blustery cold front will move across East Texas late Monday night (October 30). Here is how they believe October 31 will play out in East Texas. The Global Forecast System is American-based and under the umbrella of the National Oceanic and Atmospheric Administration. So, the major Halloween cold snap deserves a higher amount of confidence than I would usually give it. Those two models don't necessarily agree with each other when predicting the weather more than a week out, but this time, they are in agreement. I usually rely on the GFS and the ECMWF Model Charts. October 31, 2023, could be one of the coldest on record for East Texas.
