Winter (and we do mean winter) is coming to Houston

Posted by Eric Berger at 6:50 AM

Showers associated with a low-pressure system have generally moved east of our region, and now we await the arrival of a strong cold front later this afternoon that will be blustery. This will bring a freeze to parts of Houston, perhaps even most of the city, by Tuesday night. I’ll say it—Winter is Coming.

Monday

Temperatures will climb into the upper 50s today before the arrival of a front this afternoon; probably around 1 or 2 pm for central parts of the city and a little later along the coast. For the most part this should be a dry front, with only scattered rain showers, and these will end regardless later this afternoon. From that point temperatures should begin to fall as winds gust above 25mph in the city, and perhaps above 35mph along the coast bringing in chill northerly air. There is a wind advisory in effect from 2 pm Monday through 6 am Tuesday for the coast. It will be blowing out tonight.

Overnight low temperatures should generally remain in the mid- to upper-30s for the Houston area on Monday night, but with the winds it will feel quite cold outside. Wind chill temperatures for Tuesday morning will feel like the 20s for much of the region.

Just jumping in with a quick update on Sunday to call attention to some potentially severe weather later today. The overall pattern is one in which low pressure over the southern Gulf of Mexico near Brownsville will move up the coast today, and into the Galveston region tonight. This low will combine with Gulf moisture, and upper-level energy, to produce a healthy chance of showers and thunderstorms later today and tonight. NOAA has placed the region under a “marginal” threat of severe weather.

Effectively, this means we’ll see high temperatures in the upper 50s today, with an elevated chance of thunderstorms around sunset and overnight. The precise location of the storms will depend upon how far the low, and associated “warm front” move inland, but the biggest threat is probably damaging winds and an isolated tornado. We don’t anticipate rain accumulations above 0.5 inch or so for most people.

A strong cold front arrives in the area on Monday morning, and these gusty winds will bring drier conditions. Rain chances should diminish during the day, and skies should begin to clear by the afternoon hours or so. It will be a cold day in the 50s with the winds providing a chill, so bundle up accordingly.

We’re still looking at a cold week, with Tuesday night and Wednesday morning the coldest of the bunch. Chances of a freeze for inland area look decent, and we’ll have an estimated freeze line map for you tomorrow.

Good morning, and it’s a soggy one. This won’t herald a total washout this weekend, but it has brought autumn back to the region after a mostly summery week.

Today

Right off the bat, radar as of about 5:15 this morning shows numerous showers and embedded thunderstorms working across the region.

Expect off and on rain to continue all morning, gradually slowing down and becoming more infrequent this afternoon. We should dry out tonight.

The rain is actually occurring behind a cold front that has basically pushed through everywhere as of 5:15 AM.

Just about all of us are in the 50s now, and don’t expect it to get much warmer. We will probably drop another few degrees this morning before stabilizing this afternoon. By tonight, those temperatures will settle into the upper-40s to around 50 degrees.

It will also be breezy at times today, with a steady north wind around 15 mph, but higher along the coast and Galveston Bay where wind advisories have been hoisted.

Weekend

Saturday should be a bit of a gloomy looking day, but I don’t believe it will be a day where you need to adjust many plans. Look for a mix of clouds and a little sun. In the afternoon, there could be a few showers around. With a dry atmosphere, it would be unlikely that much of the moisture survives the trip from the clouds to the ground. I think the best chance for real showers or some rain to occur would be along the coast by later Saturday afternoon.

On Saturday night, expect a weak system to begin to organize offshore of Galveston. This will spread scattered showers and a chance of thunderstorms into Southeast Texas overnight and during the day Sunday. I don’t think Sunday will be a washout for everyone, but I do think most of us will see at least some rain. Near the coast, it could be heavy at times.

All told, we should see another quarter to half-inch or so of rainfall, with isolated higher amounts likely, especially on the coast or well north and east of Houston. Temperatures will top off in the mid-50s on Saturday afternoon. They shouldn’t drop much below the upper-40s on Saturday night, and they likely won’t get past the mid-50s in most spots Sunday afternoon as well.

Hi all. You get Matt the next couple days. I just want to remind y’all about our annual fundraiser that’s underway through later this month. We have two cool t-shirt designs and umbrellas available to purchase if you’d like. The annual fundraiser helps support Eric and myself and our work keeping the site on time and online. Regardless, we appreciate your kind words and support throughout the year, and we are thrilled you choose us as a vehicle to stay informed.

On to the weather, and someone has to congratulate you for surviving the hottest November day on record in Houston. We hit 89° on Wednesday, which matches, with 9 other days, the hottest November maximum temperature on record in the city of Houston. The last time we hit 89 in November? Way back on November 6th of 2017. Almost a year to the day. The latest in November we’ve hit 89° would be on November 8th, done in back to back years of 1988 and 1989.

If you’re sick of the warm, ridiculously humid weather, we have good news. The end is pretty much here. Let’s walk through the forecast.

Today

We had quite the light show last night over parts of the Houston area.

In fact, some areas did receive over two inches of rain from the storms yesterday evening.

Some locally heavy rains also fell south of Houston. With the exception of a handful of remaining showers, it’s now quiet this morning. The cold front responsible for last night’s noisy storms is now sitting offshore. It’s still a bit humid, so southern parts of our area will have patchy dense fog to deal with this morning.

Otherwise, I would expect a good bit of cloud cover today, along with a chance for some lighter rain, drizzle, or showers at times. No serious weather is expected though. It will be noticeably cooler today with high temperatures probably not getting much past the low-70s in Houston. Areas south of Houston could still push mid-to upper-70s however.

Tonight & Friday

The next cold front arrives in the Houston area tonight. As it does so, expect showers and some embedded stronger thunderstorms to accompany it on its move south. The front should arrive in the far northern suburbs around midnight, give or take a couple hours, into the Houston area after 1-3 AM, and to the coast after 3-5 AM. Unlike our cold front last week, this edition will not come with a sharp, quick clearing line. In fact, the atmosphere behind tonight’s front will remain chilly, cloudy, and damp into much of Friday. Expect showers, perhaps a thunderstorm, and periods of light rain or drizzle along with a stiff north breeze during the day Friday. We should see around one to two inches of additional rainfall with this front.

Temperatures will remain mired in the 50s most of the day. Rain chances should dwindle as we get toward evening.
