Houston’s temperatures head for a bit of a roller coaster ride after Saturday

Good morning. A very quiet couple days are ahead for Houston, followed by a cold front on Sunday, which should hopefully bring us some rainfall. We are beginning to run into a bit of a precipitation deficit again. While most of the area is technically not in drought, we are once again seeing it expand in Texas. Within the Houston region, we have gone from 9 percent coverage of drought back at the end of February to 35 percent drought coverage as of yesterday’s update. Since the first of the year, our area has seen anywhere from 40 to 50 percent of normal rainfall (with the exception being north of Conroe).

Rainfall since the beginning of the year has been rather paltry in most of the region, leading us back toward drought for at least the third or fourth time since last spring. (High Plains Regional Climate Center)

We’ve seen this happen about three or four other times since last May, and some kind of weather system or slow moving front has bailed us out from devolving into serious drought. We’ll see if that happens again this time.

Today & Saturday

Fairly similar weather is on tap for today and tomorrow. Low clouds and fog are the story this morning. Visibility isn’t severely restricted in most spots (except perhaps along the immediate coast), but we’ve definitely shifted into a murkier look this morning. The pattern the next couple days will be similar with low clouds and fog in the morning, some partial afternoon clearing, and a slight chance of showers. Any rain would be very, very spotty, and it would be unlikely to amount to much more than a few minutes or few hundredths of an inch.

High temperatures should generally be in the 70s to perhaps low-80s, with lows in the 60s to perhaps close to 70 degrees in spots.

Sunday

The forecast for Sunday is both straightforward and tricky, if that makes sense. The overall theme for Sunday is very simple: A cold front will push through, probably in the late morning and early afternoon from northwest to southeast across the region. With it, some showers and thunderstorms but probably not a ton of rainfall. We expect a couple tenths to a quarter-inch or so, with maybe slightly higher amounts north.

Where it gets tricky on Sunday is with the temperature forecast. We should start off quite warm, in the 60s to low-70s. We’ll likely bump into the mid or even upper-70s before the front sweeps through, dropping temperatures a good 10 to 15 degrees. Models differ a good bit on how far those temperatures will drop, with some saying low-50s by afternoon and others in the upper-50s to low-60s. Either way, it will turn a good bit cooler in the afternoon on Sunday, so if you’ll be out and about, be ready.

It will also be breezy, with wind gusts of 20 to 25 mph at times on Sunday.

Next week

Sunday’s front will make it about 30 to 50 miles offshore before stalling on Monday. It should come back at us as a warm front later Monday and on Tuesday, bringing a chance of showers for some of us. Eventually, a stronger cold front will likely sweep through on Wednesday, bringing another chance of showers and storms, and then cooler air and nicer weather for the end of the week.

When all is said and done, we should see about a quarter to half-inch of rainfall between now and next Thursday morning, with at least some risk for higher amounts along or north of I-10. Some places, especially close to the coast may only receive a couple tenths of an inch. It will be unevenly beneficial for our region.

Because of fronts coming at us in so many directions, temperatures will be a bit of a roller coaster ride next week. Look for low-50s Monday morning, 60s Tuesday morning, and possibly near 70 on Wednesday morning, before 40s and 50s return for later in the week. Daytime highs will offer just a little less whiplash, with near 80 or warmer on Monday and Tuesday, 70s on Wednesday depending on the exact timing of the front, and then lower-70s or even 60s on Thursday and Friday.

I have seen some continued comments and concerns about rumors of another freeze coming to Houston. That doesn’t seem to be in the cards. Certainly, late next week doesn’t look much worse than low-40s, and even that’s pretty aggressive. We may have another dose of cooler air another week after that, but no models show any risk of a freeze from that one either. We wouldn’t worry.

 

Houston’s weather to remain warm and humid until Sunday

Good morning! As we get closer to the weekend our overall pattern remains more or less the same, with three more partly to mostly cloudy warm days, a transition day on Sunday, and somewhat cooler weather next week. Overall the forecast is pretty boring, and after last year’s hurricane season and the recent winter storm, there’s nothing wrong with that.

On an unrelated note, I’ll be speaking during a couple of free, online events today you may find of interest. I’ll be speaking virtually about LIFTOFF at a Houston Writer’s event at 1pm CT, and interviewed about the book for the San Francisco-based Commonwealth Club at 5pm CT. The YouTube link for the Commonwealth event will go live at that time.

Thursday

Southerly winds will continue to blow, bringing more warm and humid air into the region. As a result, we expect continued, mostly cloudy skies today with high temperatures reaching around 80 degrees. Winds will again be noticeable out of the south, blowing as high as about 20 mph. Like Wednesday night, lows will only drop into the upper 60s for most.

Friday and Saturday

We’ll see more of the same on Friday and Saturday, although winds may slacken just a bit, and there may be a few more breaks in the clouds as sunshine peeks through. Look for highs to again hit about 80 degrees, with warm nights and plenty of humidity to spare. Rain chances will be about 10 percent both days.

Sunday

The pattern changes as a cold front pushes toward the region, and this will lead to better rain chances from the period of Saturday night into Sunday night. Most of these showers will be light, with accumulations of 0.25 to 0.5 inches for most, and skies should otherwise be cloudy. Highs will reach the mid-70s or so, and right now the front looks to move into the city during the afternoon or evening hours. This will set the stage for a cooler night, likely in the 50s.

Monday’s cooldown will be brief next week. (Weather Bell)

Next week

The front will cool things off for the region on Monday, but by Tuesday the pattern will again warm again. The forecast models now seem increasingly confident in a second front pushing through on Wednesday, which should drive highs into the 60s for the second half of next week, with lows in the 40s and 50s. Wednesday’s front should bring another splash of rain into the forecast, but nothing that looks too serious at this time.

Brisk southerly winds will amplify warming trend for the region

After several days of partly to mostly sunny skies, clouds are back on the menu for Houston, along with increasing levels of humidity. Temperatures across the region are unlikely to fall below the 60s for most areas until Sunday night, by which time a front should drop us back into more seasonable conditions.

Wednesday

A much warmer, southerly flow is in place over the region, and as a result temperatures this morning have only fallen into the low- to mid-60s across the region. In response to fairly tight pressure gradients, we’ll see onshore winds kick up again this afternoon, with gusts reaching about 25 mph out of the southeast. This humid air will allow temperatures to reach into the upper 70s, to 80 degrees, despite cloudy skies. Overnight temperatures won’t fall below the mid- 60s.

Thursday

Our sensible weather won’t change much on Thursday, although slightly increased moisture levels may allow for some very scattered, very light rain showers to develop. Highs will again be near 80 degrees with mostly cloudy skies.

Friday and Saturday

The continued flow of warmer air will lead to more days with highs of around 80 degrees on Friday and Saturday, although we may see a little bit more sunshine during the afternoon hours. Nights will remain warm and sticky, with the possibility of fog developing along and near the coast as warmer air moves over cooler shelf waters.

Sunday

At some point on Sunday our next cold front should arrive in Houston. For most of the day, however, we may see gray skies and fairly decent rain chances, with accumulations perhaps on the order of 0.25 to 0.5 inches. There may be a few thunderstorms. Highs likely will be the 70s, with a cooler night as lows drop to around 50 degrees in Houston.

Conditions will turn cooler next week. But how cool, and for how long? (Weather Bell)

Next week

The first several days of next week look cooler, but the global models seem undecided about whether a second, reinforcing front will make it through by around Wednesday. As a result, we don’t really know whether highs will be in the 60s or 80s for the second half of next week.

Texas just experienced its 11th coldest February on record

Data are in for the country as a whole in February, and it shows the contiguous United States experienced the 19th coldest February on record, which goes back 127 years. Temperatures were 3.2 degrees below the 20th century average, according to NOAA. This was the country’s coldest February since 1989.

Texas experienced its 11th coldest February on record. Notably, Austin set a record with temperatures remaining below freezing for six consecutive days, Waco had a similar record stretch of nine days, and wind chill values below zero were recorded as far south as the Rio Grande River.

Tuesday

Temperatures this morning are generally in the 50s, and will be on the rise today with partly sunny skies and warm southerly winds. Expect gusts up to about 20 mph later this afternoon as highs push into the mid- to upper 70s. Low temperatures tonight will only drop to around 60 degrees in Houston, with slightly cooler conditions possible further inland. This warming trend will continue through Saturday, or so.

Wednesday

A continued flow of warmer, southerly air will be the story for Wednesday as well. This will eventually lead to mostly cloudy skies, even as highs push into the upper 70s to possibly 80 degrees. Winds will be gusty, perhaps to 25 mph or so, again peaking during the afternoon hours. Rain chances will be low, around 10 percent, but non-zero. Overnight lows won’t fall below the 60s anywhere close to Houston.

Thursday and Friday

The story remains the same toward the end of the work week, with continued breezy weather and warming temperatures. Highs both days will likely reach around 80 degrees with a mix of sunshine and clouds.

Saturday and Sunday

Our confidence in the weekend forecast is increasing. We can now reasonably expect a continuation of this week’s weather through Saturday—so plan for a warm day with a high around 80 degrees, partly sunny skies, and a reasonable amount of humidity.

Timing of the region’s next front now looks likely to occur some time on Sunday, or Sunday night. This means we will probably see mostly cloudy skies for the second half of the weekend, with increasing rain chances during the day. How much rain? At a guess I’d say perhaps one-half inch with the potential for a few thunderstorms, but we’ll have to iron out that part of the forecast in the coming days. Highs Sunday will depend on when the front pushes through, be it daytime or the overnight hours.

The story of next week seems to be that of somewhat cooler weather to start the week, followed by a stronger front around Wednesday or so. Bottom line: We’ll feel should feel more like March, with highs in the 60s and 70s, and lows in the 40s and 50s. Details very much to come.
