Christmas week is upon us! I’m happy to report that aside from episodes of dense fog we are not anticipating hazardous weather through Christmas Day. Above-average temperatures are in the forecast for much of this upcoming week. Fog could become dense at times during the overnight hours in parts of Texas this week. We’re keeping an eye on our next storm system that will bring precipitation chances to Texas beginning Thursday night and continuing through Sunday.

Dense fog is possible by morning in Oklahoma south to the Red River, Texoma, and portions of North Texas. We also note some locally dense fog is possible in the Rio Grande Valley, Deep South Texas, and near the immediate coastline. Fog may create some minor aviation issues at BRO, CRP, D/FW, DAL, OKC, TUL, and STL tomorrow morning. Visibilities should be improving by lunch-time, although some fog may be pesky into the afternoon hours.

An area of high pressure will keep the weather across Texas mostly dry and warm through Christmas Day. Heavy rainfall will be possible on Monday across the Southeastern United States along with active weather in the western United States both Monday and Tuesday. Those traveling on Christmas Eve will find relatively good weather across the eastern half of the United States. Weather should not be too much of an impact on aviation interests in the eastern United States on Tuesday. The same can not be said for the West Coast airports, but at least there won’t be a blizzard in Denver. No significant weather impacts are expected on Monday or Tuesday in Texas minus the morning fog.

Above-average temperatures are forecast for much of the week in Texas. Christmas Day proper will feature temperatures in the 60s, 70s, and perhaps even around 80 degrees in the Rio Grande Valley. There will not be any talk of a white Christmas for Texas this year. An upper-level pattern change will bring a cold front and increased precipitation chances beginning Thursday night. Those rain chances will continue into the weekend as a cold front moves south.

An active weather pattern looks to continue toward New Years’. We’ll fine-tune the after-Christmas forecast once we get into the week. Weather model data is still out in ‘voodoo’ land and there is a lot of uncertainty in how the upper-level weather pattern will evolve. A few thunderstorms look to be possible on Friday, but instability values don’t appear high enough to support a severe thunderstorm threat. We’ll also have to see if enough cold air is present to support any winter weather in the Texas Panhandle. Anyway, the weather will remain pleasant in Texas until Thursday night at the earliest. Enjoy your Christmas!
