Houston’s highest heat of 2017 upon us

Posted by Matt Lanza at 7:10 AM

Thursday was the hottest day of 2017 to date. Hobby Airport hit 99°, tying a record last set in 1965, while Bush Airport officially hit 98° on Thursday. Friday has a chance to equal or top it, but there is some good news.

Today and Saturday

Simply scorching. High pressure remains on top of Texas. This will both limit rain chances and maximize temperatures today. Expect temperatures very near where they were on Thursday, with highs in the upper 90s to near 100° in and around Houston. Minimal relief at the coast, with Galveston through Matagorda seeing highs in the low-90s Friday afternoon.

There won’t be too many showers around today, but as we saw on Thursday, you could conceivably get one or two that pop up in parts of the area (most likely south of I-10) and dump a couple inches of rain in a short time. But the majority of the region will stay dry.

Combined with a bit of humidity, it will again feel uncomfortably hot today. Heat advisories are unlikely, but regardless, you should take it easy outside today and tomorrow.

Saturday will be similar, although the chance of showers may be just a tick higher, but temperatures will be fairly close to where they end up today. The best chance of showers will be east of I-45 and in Louisiana on Saturday. Still, a handful of downpours may occur around the Houston area Saturday afternoon or evening, and storms east of Houston could be a bit on the strong side.

We need more synonyms for heat

Heat, hot, warmth, sizzling, scorching, stifling, stupid hot. We’ve run out of words to describe it. Any (PG rated) suggestions?

STATS

The weather forecast is pretty simple, so let’s start with a few stats. This July weather has been interesting. In people I’ve talked to, the daytimes don’t seem to feel much hotter than usual. The evenings aren’t especially awful either. It’s the mornings that seem to be the problem. Through yesterday, we’ve had nine 80° mornings in Houston in July (today will not be an 80° morning). This places us 3rd on record for any July and 6th on record for any month at all. Our daytime high temperatures have averaged 96.9° this month. Our nighttime lows have averaged 79.7° for the period.

If the month ended yesterday, Houston’s July would be tied for 4th hottest during the day and warmest ever at night (and not even close). Note: The chart below contains data through Wednesday; I’ve included Thursday in the totals above.

So, yes, it’s been a hot July by any metric, even for Houston. But when you factor in the nights, July 2016 currently sits in a league of its own. Last week, Eric touched on some of the reasons why our nighttimes are getting warmer. I also think soil moisture (particularly below the topsoil), a legacy of our wet spring, as well as the warm Gulf are aiding our woes this month as well.

There also tends to be a global hangover after an El Nino of the magnitude we saw last winter, with lots of warmth lingering in the atmosphere, which may also explain a part the problem this year.

Anyway, with that, on to the forecast, with little to no good news unfortunately. Read More…

The heat goes on for Houston

Posted by Matt Lanza at 6:21 AM

Houston’s scorching stretch of weather continues. This is certainly not unusual for early July, but the nighttime temperatures certainly have been in a league of minimal, elite company. Eric discussed this yesterday afternoon. In a touch of good news, the temperature dropped below 80° around 4 AM for the first time since last Saturday.

Assuming our low is indeed 79° this morning, the last 6 days of low temperatures averaged 81.2°, it would be the warmest 6 day stretch of nighttimes in Houston’s recorded history (going back to the late 1800s).

Even if it’s “only” 78° this morning, it will tie 2011 at 81.0°. We’ll see later. It’s all statistics and knit picking at this point anyway: It has been uncomfortably hot, and more of the same is on the way.

TODAY THROUGH SUNDAY

Sunny, hot conditions will continue mostly unabated through the weekend. That being said, even yesterday we saw a handful of showers east of Houston in the late morning. As we go through the next few days, yes, there could be some showers around. Those will be extremely hit/miss, and you should probably consider yourself lucky if you end up under one. High temperatures will hit the mid 90s away from the coast without much trouble. Low temperatures will only bottom out around 80°, give or take a couple degrees, in most spots.

Again, just a note, the temperature at Big Bend is the range from high elevations (~90°) to lower elevations (~105°). All in all, it looks like a mostly trouble-free, hot weekend across most of Texas. Read More…
