Dry air maxes out today, but less humidity means a greater danger of wildfires

Good morning. Temperatures have reached the 60s for some inland locations, with much of the rest of Houston in the low- to mid-70s. With lower dew points it feels, dare I say, almost sort of pleasant outside? Thanks to a front that pushed offshore earlier this week we’ll continue to see drier air through about Friday morning. But because dry air warms quickly, we’re still going to see hot days, with highs in the upper 90s to 100 degrees. Evenings will cool off more quickly, however.

Due to the lower humidity, and somewhat breezy conditions, a “red flag” warning is in effect for pretty much the entire region. This combination of winds, low relative humidity, and warm temperatures will create the potential for explosive fire growth. Please avoid all outside burning. Do not toss lit cigarette butts outside. Report wildfires to the nearest fire department or law enforcement office.

Wednesday

High temperatures today will reach about 100 degrees for much of the metro area, but with dew points this afternoon dropping into the 50s, it genuinely will be a fairly dry heat. Close your eyes, and you’ll be able to pretend you’re in Arizona. Skies will be sunny. Winds will be out of the northeast, mostly, today at 10 mph with higher gusts to about 20 mph. Lows on Wednesday night should again drop into the 70s for much of the area.

Thursday and Friday

These days will also see a fair bit of drier air, although dew points will slowly be coming back up. Skies will be sunny, with highs of about 100 degrees. Again, mornings and nights should be fairly pleasant, at least for this time of year.

Saturday and Sunday

The weekend will see more mostly sunny skies, and highs of around 100 degrees. Humidity, alas, will be back. However, along with it we’ll see some decent rain chances. Coastal areas probably have about a 30 percent chance of a shower on Saturday, and most of the region that much of a shot on Sunday.

Labor Day and beyond

Rain chances likely peak on Labor Day, with perhaps a 40 or 50 percent chance of seeing a passing shower. These are not, for the most part, likely to be drenching and long-lasting rains. But any showers are welcome, and they’ll also cool the air. Look for highs in the upper 90s on the holiday.

Most of next week should see continued highs in the vicinity of the upper 90s, with decent rain chances on the order of 30 percent daily, or so. High pressure will be far enough to our west that some sea breeze storms will be possible. There are still no signs of truly widespread rain, which is needed to break the region’s drought, alas.

Tropics

Unfortunately, but not unexpectedly, Hurricane Idalia has blown up into a Category 4 storm overnight. Idalia is about to make landfall in Taylor County, FL, with catastrophic storm surge in the Big Bend and wind, tide, and rain impacts spreading north into Georgia and the Carolinas later. We will have full and ongoing coverage of the storm today on The Eyewall. Beyond Idalia there are no areas of concern in the tropics, as far as impacts to the United States and Caribbean Islands are concerned.
