As promised, yesterday ended up being much, much calmer, giving us a chance to exhale and dry out a bit. Things are going to pick back up again as we head into the weekend — but probably not for everyone. We continue to see a pretty healthy split in the weekend outlook, with areas west of Houston more likely to see more rain than the Houston area itself. As a result, the National Weather Service issued a Flood Watch for areas southwest of Houston for the weekend.

Those areas under the flood watch are the most likely areas to see multiple rounds of heavier rain this weekend. Areas not under a flood watch (which is most of Houston) are likely to see at least some showers this weekend, including the risk of some heavy rain. But it would most likely be manageable. That said, Eric and I will be monitoring the weather this weekend, and we’ll post an update or two if necessary or if things change, which I would caution is possible.

Today

Of the next several days, today looks calmest. Yes, there will probably be at least a few showers or storms around this afternoon in parts of the area. But those will probably be the exception, not the rule. Look for a good deal of clouds this morning, yielding to sunshine with highs well into the 80s, if not near 90 degrees.

Saturday & Sunday

I wanted to split these days up in the forecast to try and give you a better idea of what to expect each day, but the pattern over the state of Texas this weekend is far too chaotic for me to try and time anything out specifically.

Here’s the deal: If you have outdoor plans this weekend, have a backup plan indoors if needed. If your plans take you west of Houston (Austin, San Antonio, Hill Country, the Valley, you will likely run into thunderstorms at some point, including the chance of heavy rain, severe weather, and flooding. Be aware of what’s happening out that way and do your best to avoid flood prone areas if possible.

Total rain this weekend across Texas will be highest in the Rio Grande Valley through San Antonio, with high amounts into Hill Country as well. Exactly who sees the most rain is TBD. But these areas need it with widespread drought in west and central Texas.

For us in Houston, while we don’t want to be overconfident, it would appear that Saturday afternoon or evening may carry the highest risk of storms making their way into the metro area. Sunday should, should see slightly lower rain chances for Houston proper and the metro area. Both days will be warm and humid with highs in the mid-80s and lows in the 70s. Outside of any storms, we may see some sunshine. But clouds may be a bit more dominant this weekend.

Early next week

The weather pattern across Texas remains active next week, with scattered showers and storms possible. It may not rain every day, but there will at least be a chance of rain each day. We still look to see a weak “wind shift” front later Monday or Tuesday. Maybe we drop humidity a tick or two, but I wouldn’t expect much more than that. Temperatures will be generally in the mid to upper-80s by day and low-70s by night.

As noted, Eric and I will be watching the weather this weekend and update accordingly, if only to help everyone strategize their weekend plans. In the meantime, to the many moms that read our site, happy Mother’s Day!

Phew—after two days of warily watching the radar, we can take a break. Rain chances today and Friday will fall back into the 10 or 20 percent range, and we may even briefly see some sunshine during the afternoons. However, as an upper-level low pressure system evolves over Central and West Texas this weekend, it will create conditions favorable for rain there.

This means two things for our side of the state. First of all, areas west of Interstate 45 will see reasonably high rain chances in the range of 50 or 70 percent on both weekend days. And secondly, if your Mothers Day Weekend plans call for travel into the Hill Country, conditions look incredibly wet, with 4 to 8 inches of rainfall along the I-35 corridor and to the west of Austin and San Antonio. This is bound to lead to flooding and other issues this weekend there.

Thursday

Skies are cloudy this morning, but we should see some partial clearing this afternoon, and that should allow high temperatures to push up into the upper-80s. Winds will be light, out of the south. And the rain? Well, chances are about 10 percent that we see some very light showers. The air will be sticky, and lows tonight will only drop into the mid- to upper-70s. So yeah, pretty muggy.

Friday

Friday will be rather similar to Thursday, albeit with slightly stronger southerly winds, gusting up to perhaps 20 mph. Friday night will be warm again, as temperatures may drop into the mid-70s.

Saturday and Sunday

Both days will see highs in the mid-80s. Saturday is probably mostly cloudy, but Sunday may live up to its name with a little more sunshine. The question, as usual, is rainfall chances. Both days have about a 50 percent chance, and the further west of Houston you live, the greater overall chances there will be. Much of Houston probably will see less than one-half inch across both days, but areas such as Katy or College Station are at risk for 1 inch or more.

Next week

Monday should be a touch warmer, in the upper 80s, before a front arrives Monday night. You should set your expectations accordingly, and by that I mean that this front is going to bring some (very slightly) drier air to the region, but won’t modify temperatures too much. Highs for most of next week look to be in the mid- to upper-80s, with partly sunny skies, and lows in the low 70s. Rain chances remain, but overall they don’t look too high, or bring too much of the wet stuff to us.

A slowly-moving low pressure system is bringing a band of heavy rainfall into the Houston region this morning. As of 5:30 am CT the main line of storms remains southwest of the city, from Sealy to Needville to Lake Jackson. The heaviest of these showers and thunderstorms will slowly progress into the Houston area this over the next few hours, affecting the morning commute, before clearing out during the late morning hours. Based on current radar trends, the highest rain accumulations are likely to be along, and south of Interstate 10.

These storms will bring widespread accumulations of 1 to 3 inches of rain, with the potential for 5 inches or more in isolated areas. This will flood at least some low-lying streets, with the potential for flash flooding where rainfall is heaviest this morning. For this reason we are maintaining a Stage 2 flood alert for our area until the early afternoon hours. After that time we are highly confident the threat will end. Please take care when you are out and about this morning.

Wednesday

As rains wind down later this morning, and into the afternoon hours, clouds will remain omnipresent. This should help to limit high temperatures this afternoon to about 80 degrees, which certainly will be the region’s coolest day for awhile. Rain chances tonight will drop to near zero, with a low in the low-70s.

Thursday and Friday

These will be a pair of similarly warm and humid days, with high temperatures in the mid- to upper-80s, and the possibility for a bit of sunshine during the afternoon hours. Winds will generally be out of the south at 10 to 15 mph. While we cannot rule out precipitation, overall rain chances are only about 20 percent, and accumulations will be slight.

Saturday and Sunday

The weekend, I’m afraid, won’t bring much sunshine. Instead we’ll see continued high temperatures in the mid- to upper-80s with muggy air, and mostly cloudy skies. The trickier question is rainfall. At this time, due to the expected location of an atmospheric disturbance over central Texas, there looks to be a sharp east-west gradient in rainfall. Therefore we could see a situation where areas roughly east of Interstate 45 see perhaps only a tenth of an inch of rain, or two, and areas near and west of Katy see upwards of 1 inch. In terms of timing, the best chances of rainfall will come from the period of Saturday afternoon through Sunday.

Next week

A fairly weak front is going to work its way into Houston next week. It may be accompanied by some showers on Monday, and then some slightly drier air on Tuesday. Don’t have high expectations for this, but with dewpoints likely dropping back into the 60s it should feel a little bit less muggy outside. Highs should be in the mid-80s, with lows in the upper 60s to 70 degrees. We may see some sunshine, but rain chances won’t go away entirely.

As is often the case with these kinds of storms, Tuesday’s rainfall totals were hit or miss. Some southern parts of the region barely saw any rainfall, whereas a few locations around town picked up 2 to 4 inches of precipitation today and saw some street flooding. Things will now quiet down for the evening, and a few hours after midnight. However, after this time we expect an additional pulse of showers and thunderstorms to move into this area on Wednesday morning.

While this is subject to change, generally a fat line of storms should move into areas west of Houston a few hours before sunrise, push into the central part of the region just before, or during sunrise and the morning commute, and slowly continue moving to the east. The storm system will probably be clear of the area by around noon, or shortly thereafter.

The bottom line is that these storms will be pushing into Houston around the time of the morning commute, the time you’ll be dropping kids off at school or daycare, or both. Some locations will see heavy rainfall that, briefly at least, floods streets and creates traffic issues. Please be aware of weather conditions tomorrow morning, checking the radar before you leave home or work, and so on. Please also do not drive into high water.

Most of the area probably will see an additional 1 to 2 inches of rain through tomorrow afternoon, which is fine for roads. But we’re concerned about more isolated areas that see bullseyes of 4 or more inches. For this reason we’re keeping a Stage 2 flood alert in place through noon tomorrow, after which time we expect to be able to lift it. Although rain will be possible for the remainder of the week, this should be the end of the particularly threatening, heavy rainfall.
