Looking at the latest model runs the Texas Coastal Plain will see temperature departures of 10°F or more below normal. Normal temps should return to the region on Thursday and Friday. NOAA’s latest seasonal outlook for December-January-February shows a tilt in the odds for a relatively warm winter for the southern tier of the nation. Don’t let your guard down, however, as we could continue to see an active jet stream through this winter and that mean pulses of intermittent cold air.
