Hot weather this week, with the potential for rain this weekend

Monday marked the first time in more than three weeks that the high temperature in Houston did not reach at least 90 degrees, but now we’ll put our brief flirtation with somewhat cooler behind us as high pressure begins to build over the area today. Perhaps the biggest question about the forecast from now through the end of the work week is whether highs in the days ahead will reach the mid- or upper-90s.

Also, be on the lookout later today for a tropical update from Matt. There is nothing imminent, but we want to keep readers apprised of what we’re thinking and seeing as we look ahead over the next week or two in the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico. When we get into July, we probably will begin posting these on a weekly basis, and then probably more frequently during the peak periods of August and early September.

Tuesday

There isn’t much movement in the atmosphere today, which means that despite a fairly moist atmosphere any shower development should be scattered at best. High resolution models are indicating the best chances for rain may come down near Matagorda Bay, or to the northeast of the Houston metro area. In any case, for the most part we should see a mostly sunny day with highs in the low- to mid-90s.

Storms are mostly over, with Houston heating back up this week

Overnight rains and storms—there were definitely some impressive lightning displays late Sunday and early Monday—have largely moved to the coast and offshore. Most of the region saw 1 to 3 inches from Sunday through this morning although a few locations, including parts of Montgomery County, saw totals of nearly 4 inches. One benefit of Sunday night’s storms is significantly cooler weather this morning, with rain-cooled lows in the upper 60s for much of Houston. Enjoy this while it lasts.

Monday

The atmosphere is pretty worked over, so although some light rains will be possible today, we’re unlikely to see any real storm activity except near the coast (seas offshore are choppy, to say the least). With lingering clouds, however, temperatures today may only rise into the mid-80s for most of the region. Houston has reached 90 degrees every day so far this month, so that would offer a nice reprieve from the summertime heat we’ve been experiencing. Skies should be partly cloudy tonight, with lows in the mid-70s.

Showers and thunderstorms likely from Sunday afternoon through Monday

The Houston region appears likely to see an increasingly wet period beginning later this afternoon through at least Tuesday morning as atmospheric moisture levels spike above normal, and the absence of high pressure allows for the formation of showers and thunderstorms. To be clear, we’re not really expecting any significant flooding for most people—at least not beyond some street flooding—just the potential for several rounds of storms. Check the radar later today before embarking on any outdoor plans.

Unfortunately, it is hard to offer too much detail, as there is not great agreement among the high-resolution models about what will take place later today, tonight, and Monday. At a best guess, the potential for heavier rainfall should remain to the west of Harris County, and north of Montgomery County, through the early afternoon hours Sunday, but after that all bets are off.

At some point we are likely to see showers and potentially stronger thunderstorms sag into the metro area—moisture levels may peak after midnight tonight for central and coastal areas of Houston—and this will lead to better rain chances. At a best guess, most of the region will see 1 to 2 inches of rainfall through Tuesday morning, but as always there will be the potential for higher isolated totals, and some people are likely to miss out entirely. Most of Houston hasn’t had much, if any measurable rainfall in 11 days so some precipitation will be welcome for most.

We’ll be watching things later today and will update if needed.

 

Reliant is giving away two complete AC systems this summer

As this weekend so effectively demonstrated, summer has begun in Houston. And with July, August, and September around the corner, we’re facing several months of high heat. So, this is the perfect time to announce a pretty amazing contest that our friends at Reliant have come up with. They’re teaming up exclusively with Space City Weather to give away two complete, brand new air conditioning systems, with delivery and installation included, to our readers.

Yes, really. You can enter the contest here.

Reliant has sponsored this site for two full years now, and they really value what we’re doing to keep the greater Houston area informed about weather in a reliable and sensible way. To show our readers how important they are to Reliant, the company will award two air conditioners worth an estimated $11,000 each.

There really are no catches to this. Reliant just wants readers to know they appreciate Space City Weather, too, and to let them know about their AC Heat & Repair business.

A quick summary of the rules appears below, but for full rules and details of the contest, click here.

  • One AC unit will be given away to entrants between June 10–July 10
  • One AC unit will be given away to entrants between July 11–Aug 13
  • One winner will be chosen, randomly, at the end of each phase
  • Winners must be 18, and own a home in the greater Houston metro area
  • Your AC system must be 8 years or older

If your air conditioning system is not more than eight years old, or more importantly, if you know someone who could really benefit from a free, new AC system heading into the hottest time of the year, please share the contest link with them.

Update

We have our first winner! The winner of round one of Reliant’s AC giveaway—Farrah Gauge is thrilled. She told us: “What an incredible gift! Our current A/C is 18 years old and definitely on its way out so this could not have been better timing. You have gained a lifelong customer and advocate. Thank you Reliant!”
