Month: April 2023

Good morning. Today will be the region’s last “hot” day for awhile, with temperatures in the upper 80s. A cold front will arrive on Wednesday to usher in several cooler and wetter days for the region. Because of the potential for rainfall accumulations over time, we have issued a Stage 1 flood alert for the period of noon on Wednesday through Friday. This means you can anticipate the potential for at least some nuisance street flooding. I do expect the rainfall to end in time for Easter Sunday, by which point the weather should be fairly pleasant.

Tuesday

Skies will be mostly cloudy today with a pronounced southerly wind, at about 15 mph, with gusts up to 30 mph. Highs will reach the mid-80s, at least, with plenty of humidity. Winds will continue through most of the overnight hours, with low temperatures only dropping into the mid-70s for most.

Wednesday

The morning will start out warm and cloudy. It now appears that the cold front will not reach central Houston until around noon or the early afternoon hours. There will probably be a broken line of showers and thunderstorms with the front as it moves through on Wednesday and pushes just off the coast. While there is the possibility of heavy rainfall during this time, it is important to note that I do not think this will be the “main event” when it comes to rain this weekend. That probably will come on Thursday and Friday. Temperatures will drop back into the upper 60s after the front’s passage, and down to around 60 degrees on Wednesday night.

Thursday and Friday

These two days will serve as the focus for heaviest rainfall as the aforementioned front more or less gets hung up right along the coast. Stalled fronts, which open the door for atmospheric disturbances, have historically been rainmakers for Houston (Tax Day floods, anyone?). Precisely where this front stalls out is not yet determinable, but that will be where we can expect the heaviest rain. Highs, generally, will be in the 60s.

For now I’m going to ballpark rain widespread rain totals of 2 to 6 inches of rainfall this week, with higher isolated totals. Most of this will come sometime on Thursday and Friday. There won’t be continuous rainfall during this period, but there is the potential for at-times heavy rainfall that could cause some street flooding—hence the issuance of a Stage 1 flood alert. This basically means that you need to be weather aware before venturing out. It probably will be fine, but check to make sure. Matt and I will be covering the heavy rainfall as much as needed.

Saturday

We’re still going to see about a 50 percent chance of rain on Saturday, but things should be winding down as the stalled front finally gets un-stalled and moves away. Otherwise, expect cloudy skies and high temperatures of around 70 degrees. Overnight lows will drop into the low 60s.

Sunday

By Easter Sunday we’re down to about a 10 or 20 percent chance of rain. Skies will probably start out cloudy, but by the afternoon we could see some sunshine peaking out. Highs will likely reach the mid- to upper-70s. Lows on Sunday night will drop into the mid-60s.

Next week

Overall our weather next week looks comparatively calm, with partly to mostly sunny skies, highs in the mid-80s, and lows somewhere in the 60s. Humidity returns, but at this point it looks like dewpoints will not be impressively high. So, not bad for mid-April?

Good morning. This week will offer something for everyone. We’re going to start off with some of this year’s warmest weather so far, with inland areas of the region likely to hitting 90 degrees this afternoon. Then on Wednesday morning a cold front will push into the region and stall along this coast. This will destabilize the atmosphere and lead to a prolonged period of on-and-off shower and thunderstorm activity from Wednesday through Saturday.

While there is no one focus for particularly heavy rainfall during the second half of this week, there is the potential for 1 to 2 inches each day and night, and over time this may lead to some street flooding. For this reason we are issuing a Stage 1 Flood alert for the period from Wednesday through Saturday afternoon. This means we are likely to see nuisance street flooding, for the most part. If the data changes, we may need to adjust the alert warning, but for now we expect Stage 1 to cover things.

Monday

Are you ready for some heat? With high pressure in place and a warm southerly flow, temperatures will warm into the upper-80s for most of the region. Whether you reach 90 degrees will depend on how far you are from the coast, and the extent to which the Sun emerges from behind the clouds today. Most areas inland of Interstate 10 have a good chance of hitting 90. Winds will be out of the south at 10 to 15 mph. Clouds return this evening, with lows dropping only into the mid-70s.

Tuesday

This will be another warm and humid day, although mostly cloudy skies should limit high temperatures to the upper 80s. Winds out of the south will be noticeable, perhaps gusting to 25 mph. Expect another warm night.

Wednesday

Although the timing is yet a bit uncertain, a cold front will reach the Houston metro area during the late morning hours or around noon on Wednesday. It looks like this front, with a line of showers and thunderstorms, will push just offshore and then simply stall for a few days. This will open up the region to a series of disturbances through the end of the week. Temperatures will fall into the upper 60s, roughly, as the front passes, with overnight lows dropping to around 60 degrees.

Wednesday night through Saturday

The next three nights and days will bring an elevated chance of rainfall. Totals will vary widely and are as yet uncertain, but most locations will probably see 3 to 6 inches of rainfall, with isolated areas seeing more. At this time it looks like rain accumulations will be highest in the tier of counties just inland from the coast—Fort Bend, Harris, and Liberty Counties. We are issuing a Stage 1 Flood Alert at this time because our region’s dry soils should be able to handle rainfall over a three-day period. Some street flooding is possible, certainly, especially toward the end of the week as accumulations mount. We’ll be watching the situation closely in case we need to elevate the flood alert level.

In terms of temperatures, we are likely to see highs in the upper 60s through Saturday, with lows in the upper 50s to lower 60s. We won’t see much, if any, sunshine until Sunday.

Sunday

Fortunately for those concerned about Easter Sunday, it does look like this weather system should move off to the east by Saturday afternoon or night. That’s cutting it close, but for now it looks as though rain chances will be low on Sunday, with the possibility for partly sunny skies by the afternoon. For now I’ll ballpark high temperatures around 80 degrees, with moderate humidity.

Next week

Most of next week is likely to see highs in the low 80s, with lows in the mid-60s. Humidity levels do not look unreasonable for mid-April. We should have several days, at least, to dry out after rains this week.
