Winter roars back into Houston today

It’s quite warm this morning across Houston, with low temperatures only falling into the mid-60s for most of the area. But don’t let that fool you—a strong cold front will blow through the area today and change our weather through the weekend.

Thursday

Our muggy (for winter) conditions will prevail this morning, allowing high temperatures to likely rise into the low 70s for much of Houston. However, a line of showers will develop later this morning, and move through the region between about 10am and 2pm, with the cold front at the back end of these showers. Most areas shouldn’t see more than a tenth or two of an inch of rain as the storms move through fairly quickly. In their wake we’ll be left will very blustery conditions, as gusts may rise to about 30mph this afternoon and evening. (A Gale Warning is in effect for offshore, where seas will be rough. This afternoon and this evening would be a very bad time to take the boat out.) All of this should lead to a chilly night, with a light freeze for the northern half of Houston, and wind chills down in the 20s.

We’re warmer for a bit, then a blustery front will reach Houston

Parts of the Houston region, particularly the western half of the area, are seeing dense fog this morning. Sunrise, and later increasing winds, should help break up the fog by mid-morning but until then please take caution on roadways.

Wednesday

Even after the fog clears skies should remain gray today, with winds picking up out of the southeast as the onshore flow gets a bit stronger. Expect highs in the low- to mid-60s, with not much of a temperature drop off tonight.

Thursday

These somewhat stronger winds during the overnight hours should help to limit the development of fog on Thursday morning, although it’s still possible given warmer air and moisture in the atmosphere. Highs Thursday should reach up to near 70 degrees before a front moves through, probably sometime during the early afternoon hours. It appears as though some line of showers and thunderstorms will accompany the front, but this system should move through fairly briskly on its way toward the Gulf of Mexico. I wouldn’t anticipate accumulations of more than a few tenths of an inch of rain.

Wind gusts could be in the 30s for parts of Houston on Thursday evening and Friday morning due to the front’s passage. (Weather Bell)

Winds should really kick up behind the front, and the National Weather Service has issued a gale watch for waters off the coast with rough seas anticipated Thursday night into Friday morning.

Parts of Houston could return to the 20s this weekend

Officially, the mercury in Houston has yet to hit 70 degrees in 2018. In fact, we haven’t gotten that warm since Dec. 22. (This is, like, a real winter). Anyway, we have a chance to get close to 70 degrees this week before the region gets quite cold again this weekend.

Tuesday

Not much to say about today, as we’ll see partly sunny skies and high temperatures in the low 60s. Winds won’t be appreciable today and lows tonight will probably only fall to around 50 degrees. Should be very nice for January.

Wednesday

As the onshore flow returns Tuesday night, the region should see a partly to mostly cloudy day on Wednesday, with the potential for some fog during the morning hours. Highs should climb into the mid- to upper-60s, and we could hit 70 degrees if the Sun breaks through for long enough.

Thursday

We’ll start the day out warm before a cold front moves through the area during the daytime hours. I’m not expecting anything severe, but the front’s push through the area could be accompanied by some brief, heavy rain showers.

Still, because the system should move steadily from northwest to southeast, I don’t expect accumulations above a few tenths of an inch of rain for most areas. Areas far inland on Thursday night could see a light freeze, but I expect most of the city to remain above freezing on Friday morning.

Normal winter weather this week in Houston, with a cold weekend ahead

The region’s latest cold front made a dramatic entrance on Sunday night, dropping anywhere from 0.25 to 1.5 inches of rain across the region as it pushed through. The rain was largely welcome, as Houston had yet to see much precipitation in 2018, and little is expected for much of the rest of this week. Instead, we can expect a steady diet of mostly clear, mostly cool winter-like weather. The weekend weather turns colder.

Monday and Tuesday

High pressure should assert control over Houston’s weather, allowing skies to clear later this morning. Although high temperatures should rise into the low 60s, brisk, northerly winds will make it feel chilly outside. Winds should begin to subside later this evening, and overnight lows will dip into the mid-40s—near normal for this time of year. Tuesday should be a nice day, with less wind and similar temperatures (highs in the 60s, lows in the 40s) beneath mostly sunny skies.
