Heavy rain likely on Wednesday for most of Houston

The weather story for this week continues to be the potential for heavy rainfall late tonight through Thursday morning, with subsequently clearing skies and really quite nice weather for Easter weekend. Let’s jump into the timing for this week’s storms.

Tuesday daytime

Temperatures are very warm this morning for late March, with lows only dropping into the low 70s. Even with mostly cloudy skies, we can expect high temperatures today to rise into the lower 80s. And while there will probably be some scattered showers later this afternoon, I think we’re probably going to have to wait until Tuesday night for the heavier rain to begin.

Tuesday night through Wednesday

A slow-moving cold front will be part of a large area of disturbed weather moving toward the greater Houston area tonight, and right now it appears as though any heavier showers probably won’t reach the metro region until after midnight. The general expectation remains 1 to 3 inches of rainfall for most people, with isolated, higher totals possible through the day on Wednesday.

Houston needs rain, and Houston is going to get rain

Except for a few areas of Fort Bend and Brazoria County, the greater Houston area is not under a drought—or even abnormally dry—and yet much of the area has begun to accrue a rain deficit for 2018. For example Hobby Airport, a good marker for central Houston, has received less than one-half inch of rain in March. And with extremely heavy levels of tree pollen still around, we could use a good shower (or two) to knock the pollen out of the air and wash it away. Well, that’s what is coming this week.

Monday

Monday will probably end up being similar to Sunday temperature-wise, although there will be a few more clouds, some slight rain chances, and some gusty southerly winds. Most people probably won’t see rain, but the breezes will definitely be felt as winds gust into the mid-20s. Highs in the low 80s.

Quiet weekend, but Houston humidity returning

After a string of splendid weather, we’re heading back into the muggy warmth of mid-spring in Houston. We’ll cap it with some rain chances next week. Maybe we can finally wash away some of the pollen that has been driving some of us crazy. (raises hand) Let’s dive in.

Today through Sunday

The quick and dirty here is that if you have outdoor plans this weekend, you should be in good shape. There could be a few showers around, but for the most part, I feel fairly comfortable telling you that the weather will be quiet this weekend.

We have a few patchy low clouds around this morning that should dissipate. Expect new clouds to billow up at times today, but on the whole it looks fairly nice. Expect a little more humidity and high temperatures approaching 80 degrees.

I think Saturday and Sunday may play out similarly with nighttime through morning low clouds or a few sprinkles giving way to partial afternoon sunshine, fairly typical for Texas springtime. Again, there’s a very, very slight chance for a shower. But as Eric mentioned yesterday, a pretty firm capping inversion probably keeps us dry the vast majority of the weekend. Both Saturday and Sunday should see highs in the low 80s and morning lows struggling to get below the upper 60s.

With stronger onshore winds early this weekend and next week, use caution if you’ll be at the beach, as rip current risk will be higher than usual. (NWS Houston).

Headed to the beach? Be aware that as onshore winds increase today and this weekend, so will the risk of rip currents. If you do decide to take a dip in the Gulf, please do so cautiously.

Pleasant today, but muggy nights are coming for Houston

It’s a bit warmer across Houston this morning, but still feels like a fine spring morning with low temperatures ranging from the upper 40s to mid-50s across the area. Houston will now enter a period of warmer nights—generally 60 degrees and above—that should last for the next week.

Thursday

We should see one more pretty great spring-like day, with high temperatures generally in the mid-70s across the region, and mostly sunny skies. Winds will begin to swing inland, however, and this will set the stage for warmer, more humid days ahead. Low temperatures on Thursday night will be about 5 to 10 degrees warmer than the day before.

Expect another seasonable, pleasant day across Houston on Thursday. (Pivotal Weather)

Friday

The warming trend continues on Friday, with a few more clouds, a bit higher humidity, and highs probably reaching 80 degrees for most of Houston.
