Goodbye to the 40s, perhaps for months, and hello rain

Temperatures in much of Houston, including the official weather station at Bush Intercontinental Airport, dipped into the upper 40s on Wednesday morning. The question I’m left with is whether this will be the last time that happens this year until November. For example, in 2018, the final 40-degree night came on April 16, and the region didn’t get another one until Nov. 10. The next few weeks look fairly warm, so at this point I would bet on saying goodbye to the roaring 40s for at least the next six months. But no guarantees just yet.

Wednesday

We’ll also say goodbye to high pressure for awhile, as it has moved to the east, to be replaced by a warmer and more moist airmass. As a result rain chances will be on the upswing from tonight through the weekend. Today should be a mostly cloudy affair, with highs of around 70 degrees. We can’t entirely rule out some scattered rain chances today for the Houston region, but any heavier showers will likely hold off until after sunset. Overnight lows will be warm, in the mid-60s.

Thursday

Better rain chances will come late Wednesday night and through Thursday morning, with accumulations of perhaps a few tenths of an inch up to (at most) one-half inch through about noon. This shouldn’t be too disruptive, and rains should end during the afternoon hours. Some sunshine may even peek out before sunset. Highs will be around 80, with mostly cloudy skies, and again warm nights.

Houston sets a record low Tuesday, but spring returns later today

It’s another very cold morning for early April, with temperatures in the 30s for much of the metro area away from the coast. The low at Bush Intercontinental Airport dropped to 37 degrees this morning, which breaks the record low temperature for this day (38 degrees) set in 1996. This has been the region’s strongest April cold front in at least 20 years, although it can’t rival 1973, when a freeze was recorded in Houston as late as April 10. Anyway, after this morning, we’re done with very cold nights like this not just for now, but probably until November.

Tuesday

After the cold start, we’re in for a gorgeous day. Expect full sunshine, with highs around 70 degrees, dry air, and light winds. In short, today should be nigh on perfect. Lows tonight will fall down to around 50 north of Houston, with mid- to upper 50s along the coast. For my tastes, I could not draw up a more perfect day.

Wednesday

By Tuesday night or Wednesday morning, the onshore flow will resume, and we can expect increasing clouds. While we can’t rule out some rain, chances are 20 percent, or less. Highs will be in the low 70s. Overnight temperatures Wednesday night aren’t likely to fall below the mid-60s.

Enjoy winter’s last gasp, Houston. You know what’s coming.

Temperatures have reached the mid- to upper-30s across the northern reaches of the Houston metro area this morning, offering the region a final, fleeting taste of winter. As of 6:20 a.m. CT, the mark of 39 degrees at Bush Intercontinental Airport ties the record low for today, set in 1989. It is, indeed, quite chilly out with a light northerly wind, so dress accordingly this morning.

Monday

Skies will be clearing today, but with a bit of unsteady air aloft, we can’t entirely rule out a few stray showers this afternoon. However, most of us will not see rain, but rather partly to mostly sunny skies, and highs of around 60 degrees. This is nearly in line for normal low temperatures this time of year. Lows Monday night will be cold again (see map below), but temperatures probably should be a couple of degrees warmer than Sunday night.

Monday night will offer one last, chilly night for this spring. (Pivotal Weather)

Tuesday

An absolutely splendid day: Highs around 70 degrees, mostly sunny skies, light winds. Overnight lows in the 50s. Play hooky.

Wednesday

Moisture will be returning inland later on Tuesday, and that will allow for the development of clouds on Wednesday. Rain chances are low (about 20 percent) but not non-existent, as highs push into the mid-70s (it will be even warmer if the sun can break through the clouds for a bit).

Amazing, sunny weather ends before the weekend in Houston

It’s been a grand, spring-like week with lots of sunshine and dry air for Houston. That splendiferous pattern will soon end as the weekend approaches.

Thursday

After a few clear and sunny days, some clouds are beginning to return to the sky this morning as winds turn east. Today will still see some sunshine, and this will allow highs to get into the mid- to upper-70s. Later this afternoon winds will turn out of the southeast, and gust up to 20mph signalling the return of much more moist air.

Lows Thursday night will be warmer than what we’ve seen this week. (National Weather Service)

Friday

Skies will turn mostly cloudy, as high pressure completely exits the region off to the east later on Thursday. Winds will continue to blow out of the south, and southeast throughout the day. This will allow for a slight chance of light rain showers across the region, but chances appear less than 20 percent. Highs will get up to near 80 degrees, despite the clouds, and it’ll feel quite humid outside.
