The Sun to remain a stranger for most of this week in Houston

It is quite cold this morning across Houston, with lows ranging from the mid-30s across northern portions of the region to around at the coast. The good news is that we’ll see warmer temperatures for the rest of this week—but the bad news is that the Sun is going to remain mostly a stranger to our skies.

It’s a very cold start to Monday in Texas. (Weather Bell)

Monday

A slight northerly wind, in concert with cloudy skies, will keep Houston on the cool side. I expect highs today to remain at about 50 degrees. So, a cold morning, and a cold day. Low temperatures Monday night will probably be about 10 degrees warmer than on Sunday night, however.

Tuesday

A bit warmer than Monday, but cloud cover should again help to keep temperatures bottled up in the 50s. Temperatures may not reflect it, but higher moisture levels will be returning to the area, and we could see some scattered, briefly heavy showers throughout the afternoon and evening hours on Tuesday. For the most part I wouldn’t be concerned with accumulations, as they should only measure at a few tenths of an inch.

Wednesday and Thursday

Some slight rain chances remain, but the bigger story on Wednesday will be the movement of warmer air into the region from the south. Despite clouds on Wednesday, we should see highs in the mid-70s, and these temperatures could reach 80 degrees on Thursday with (hopefully) some partly sunny skies. Nighttime temperatures should only fall into the 60s. By the way, Houston has yet to officially hit 80 degrees in 2018.

Heavy rain possible on Saturday morning in Houston

Sorry for the late post this morning. I’m still traveling, and Matt had some other business to attend to this morning. We’ll be back to our regular schedule next week. In the meantime, I’m unhappy to report that Houston’s weather still looks fairly lousy.

Friday

As the onshore flow ramps back up today, we can expect to see warmer conditions, with high temperatures near 70 degrees. There’s the possibility of a few scattered showers later this afternoon, but for the better rain chances we’re going to have to wait for tonight and Saturday.

Saturday

Ugh. We’re going to see a spike in atmospheric moisture levels beginning Friday night and into Saturday morning, and in combination with divergence over head (which allows the warm, moist air at the surface to rise), we’re going to see a really healthy chance of rain showers beginning Friday night and through part or most of the day on Saturday.

A surge of moisture (shown here in precipitable water) will move into Texas and Louisiana on Saturday morning. (Pivotal Weather)

Right now the best chance of heavy rain seems likely to come on Saturday morning, when a few areas could see some rainfall rates of 1 to 2 inches per hour during the heaviest storms. This could be enough to cause street flooding, so please take care if you plan to be out and about. Overall, I’d anticipate widespread accumulations of 1 to 3 inches, which higher isolated totals possible. Highs Saturday will be around 70 degrees again. We’ll watch the potential of flooding for you, and update if needed.

Houston to get wet this week, and weekend

Good morning, everyone. It will be a fairly quick post this morning, as Matt is traveling, and I’m in Florida for the Falcon Heavy launch, which may liftoff as early as 12:30pm CT today. (If you’re interested check out these photos of me and Elon Musk near the launch pad on Monday).

Tuesday through Wednesday morning

A warm front has essentially stalled along the coast, and this is creating foggy conditions across much of the area, which may linger into the mid-morning hours. “Clearing” skies is a relative term, as skies will remain cloudy throughout the day. As that warm front lifts back north, it will generate some showers and probably some thunderstorms later this afternoon across the area, with the greatest potential for severe weather to the north-northeast of Houston. I expect most areas will see about one-half inch of rain today, give or take, as temperatures top out at about 70 degrees.

It will be a wet week for southeast Texas, with much of Houston picking up 1-3 inches of rain from now through Monday. (Pivotal Weather)

Wednesday

A cold front will push through the region early on Wednesday, likely moving through the city by or before sunrise. This will not immediately scour the rain chances from Houston, however, and I expect most of the region to pick up another half inch of rain, or so, before the region finally begins to dry out later on Wednesday, or Wednesday night. Temperatures will be quite a bit colder behind the front, so look for readings only in the low 50s on Wednesday after the front moves through.

Mixed weather this weekend, but nothing too extreme ahead

The onshore flow has kept temperatures generally in the 50s across the Houston area this morning, and as a result we’re seeing the development of some fog across the area, although visibilities for the most part remain OK.

Thursday

We should see partly sunny skies later this morning, and this will allow high temperatures to climb into the mid- to upper 70s, with Houston possibly seeing its warmest day of the year. As moisture levels rise and a front drops out of the north, we may see a some scattered, light rain showers this afternoon, evening, and during the overnight hours. However anything that forms should not be threatening. The front itself could reach the northern part of the metro area by or before sunset today, and move through the region during the overnight hours.

Dewpoint temperatures for 6pm Thursday evening show much drier air behind the front, and the coast still remaining pretty humid. (Weather Bell)

Friday

Any rain should end after the front moves through, and we’ll be left with a chilly day Friday as northerly winds blow in, and highs struggle to climb above the mid-50s. Mostly cloudy skies will add to the winter-like ambiance.
