Summer officially began Friday, though most everyone in Texas was already in full meltdown. Heat advisories were commonplace across the southern half of Texas the week before, with indexes reaching into the 110-115-degree range.
Luckily, a wave of showers Monday and possibly during the rest of the week should lead to enjoyable Fourth of July celebrations (see: County overflows with Fourth of July events, on this page). The humidity may rise, but a related cooling effect will likely cap temperatures.
“Rain does more help than harm when it comes to the heat,” said Max Crawford, meteorologist with KBTX in Bryan. “Yes, it’s more humid in the morning, but by afternoon, temperatures are lower.”
The National Weather Service does predict that temperature will rocket up to the 90s for the remainder of this week. But Crawford points out that heat indexes – the “feels like” temperature – will not reach the levels of mid-June for at least another week.
“Don’t get me wrong, it’s still going to be hot,” Crawford said. “We’re going to be at average or below average temperatures, but that still puts us in the low 90s.”
However, the heat will be less dangerous for those outside.
“My thought is we don’t have a heat advisory issued for the rest of June and the first week of July, he said.”
According to the Mayo Clinic, the main factors in heat exhaustion and heat stroke – other than the actual temperature, of course – are dehydration, which reduces your body's ability to sweat and maintain a normal temperature; alcohol use, which can affect your body's ability to regulate your temperature; and overdressing, particularly in clothes that don't allow sweat to evaporate easily.
Crawford cautioned that you can still experience heat exhaustion or heat stroke with temperatures in the low 90s, but it’s much safer than the high 90s of mid-June. But it’s still going to be hot.
“It is summer,” Crawford said.
“Wednesday into Thursday upper level ridging should become more pronounced over northern Mexico, southern Rockies and into the Plains. SE Texas will be on the edge of this ridge so we will need to carry at least 10 to 20 [percent probability of precipitation] as there will still be some decent moisture over the area,” the NWS reported in a forecast discussion.
