In brief: There has been a lot of uncertainty about the extent to which the coldest air from this coming week’s Arctic freeze will push all the way down to the coast. It now looks like Houston will be spared the very coldest conditions, so be thinking more along the lines of a light freeze in the city rather than a hard freeze.
Good morning on a beautiful, if chilly Sunday morning. We’re just jumping into your timeline with a weekend update because we finally have some higher confidence in how cold temperatures will get this coming week. If you recall, during the second half of last week, in our forecasts, Matt and I were hedging our bets on somewhere between very cold (low 20s) and not quite so cold (low 30s). At this point we’re leaning toward the milder end of the spectrum, which is good because it would likely spare the majority of the Houston metro area from a hard freeze.
Forecast quick look
Today is going to be cold, with highs in the 50s, and we’ll see a night with temperatures near freezing on Monday morning. Inland areas may even see a light freeze. But then we’re going to see a warmup on Monday and Tuesday, with highs potentially reaching 70 degrees. Rain showers are likely ahead of the next front on Tuesday, which will send temperatures plunging on Tuesday night. The big question has been how much of the Artic air that is going to spill into the lower United States will make it all the way down to the Texas coast. The answer, at this point, seems to be that the coldest air is going to get shunted off to the east.

Thursday morning freeze
We’ll have full details in our Monday forecast, but the bottom line is that low temperatures in Houston on the coldest morning next week, Thursday, are likely to be closer to 30 degrees than 20 degrees. Some areas south of Interstate 10 may not even freeze. Some areas along and north of Highway 105 may still see lows of 25 degrees or below. So the bottom line is that yes, it is going to get cold this week. But not as cold as we experienced in January, and with no precipitation in the cards during the coldest time periods, impacts will likely be minimal. More tomorrow!
