Cooler weather and decent rain chances return to Houston, but will it deliver?

We officially topped off at 101° yesterday for the third straight day, but we think the next few days will feature more tolerable temperatures, as rain chances inch upward. And it’s needed, as drought has expanded across the Houston area with 12 percent of the area in exceptional drought (level 4/4).

This was underscored by the deadly grass fire in the Cypress area yesterday. Grass fires can happen in the Houston area, so please use caution, even if you get a good bit of rain in the coming days.

Today

With a disturbance in the middle levels of the atmosphere moving toward Matagorda Bay, we are already seeing numerous showers and storms develop — over the Gulf.

Rainfall is almost entirely offshore this morning, but we should see trends bringing some of this onshore throughout the day. (RadarScope)

As the day goes on, we’ll see rainfall expand onshore. I still don’t think everyone will see rain today, but most places near the coast should see showers, with more scattered coverage as you go inland from there. Storms should move slowly but steadily today, so areas with the most persistent rains could see an inch or two, while some neighborhoods will only hear distant thunder. But coverage will be greater than it has been in recent days.

With clouds and showers nearby, look for highs ranging from the upper 80s at the coast to low 90s in Houston to middle or upper 90s to the north and west.

Weekend

We’re going to maintain pretty healthy rain chances into Saturday. Again, not everyone will see rain tomorrow, but there should be coverage along the lines of what we see today; initially at the coast in the morning, spreading inland as the day progresses. Rain totals will range from nothing to an inch or two in the most persistent or slowest moving storms. Morning lows in the 70s will give way to daytime highs similar to today, with upper-80s to low-90s for Houston south and east, building to the upper-90s to near 100 or so from Columbus to College Station to Madisonville.

Sunday looks to see very similar weather, with hit and miss storms and temperatures about where they will be on Saturday.

While some places will see more rain and others less rain than shown here, this NWS outlook gives you an idea of how rainfall should be distributed today through Sunday, highest at the coast, least inland. (Pivotal Weather)

Overall, rain totals should average a quarter to half-inch or so across the area, with some neighborhoods seeing several inches of rain and others seeing next to nothing. Yes, someone will end up disappointed from this period of higher rain chances, but it’s our best opportunity in some time.

Early next week

Rain chances should ebb heading into Monday and Tuesday, or at least be more co-located with the daily sea breeze off the Gulf. So coverage should diminish but not disappear completely. Temperatures will respond, back up to the low-90s along the Gulf, mid-90s in Houston, and near 100 well inland.

Later next week

The back half of next week is sort of in flux right now. One model (the Euro) is trying to bring a front into our area, which would enhance shower and storm coverage, though it would be unlikely to bring heat relief. The GFS keeps that away, but it does have higher rain chances later next week. Bottom line? We need a couple days to sort out late next week. But expect some rain chances and hot (but not extremely hot) weather.

Tropics

All remains quiet into early next week.

  1. There is tghe key headline, buried at the end. “All remains quiet into early next week.”

  2. Keep in mind that the drought monitor maps are only really looking at medium- to large-scale precipitation data. So, the maps that come out each week are generalized. This helps to explain why Harris County is all in either the severe or extreme categories, while parts of the area, especially eastern parts of the county, get substantial rains a few times a week over the past several weeks. These precipitation events do not appear to be captured in the map.

  3. Well, it started raining lightly around 12:50 and the temperature hasn’t gone above 87F (now 79F). Some payoff, at least in terms of temperature and giving my poor A/C unit some relief today. Rain – we’ll see. but the drought around here isn’t as bad as shown on the drought maps. It’s not like we’re having trees die or having grass fires.

    Then again, as bad as the city’s water system is, we’re probably getting taxpayer funded watering from system leaks.

    • In Addicks reservoir there are trees turning brown here and there. And it looks like it is only severe drought there on the map.

  4. It is raining hard right now (1:57 pm) in TheWoodlands (Gorgans Mill). It has been so long since it has rained that I almost forgot what it looked like, ha!! Pray for more.

  5. Well as usual all it did was sprinkle for a few minutes in Sweeny. At least the cloudy skies kept the temperatures down a bit today. But it didn’t help out my scorched backyard with 2 inch wide cracks everywhere
