We topped off (officially) at 97° on Thursday, tying yesterday with June 9th for the hottest day of 2020 so far. Perhaps we could make a run today for….
Maybe. If not, there is a valid chance we could do it Saturday or Sunday as well. Either way, expect a hot holiday weekend, and be sure to take it easy if you’re outdoors.
Look for partly to mostly sunny conditions today. Saharan dust will again provide some haze. Air quality on Thursday did get to the “unhealthy for sensitive groups” level, and it may do so again today, so if you’ve been irritated by the recent dust events or have any respiratory ailments, today may bother you once again. High temperatures should aim for the mid- to upper-90s once more with plenty of humidity. Heat index values topped off around 105° yesterday. We should see similar to perhaps slightly lower peak heat index values today.
Rain chances aren’t zero, but they’re low for most of the area most of the day. We will watch some storms in Louisiana later this afternoon that will ride west into Texas this evening. If they can survive the trip, you may see a downpour or have a brief gusty thunderstorm east of I-45 after about 4 or 5 P.M. or so before the storms dissipate. This is a fairly low possibility.
For the holiday weekend it will be hot. Both Saturday and Sunday should again see highs in the mid- to upper-90s and lows in the 70s. Humidity is going to creep upward this weekend, so look for peak heat index values around 105°, give or take a couple degrees on both days. Saharan dust may linger a bit, but it will slowly dissipate this weekend.
How about rain? Well, a trough and upper low look to setup shop over Mississippi and Alabama this weekend. Storms on the western periphery of that setup could graze eastern areas. This would be primarily a story for Liberty & Chambers Counties, if not mainly toward Beaumont. So a few heavy downpours are possible east of Houston. Areas to the north (Walker, Montgomery, and San Jacinto Counties) may also get grazed by some storms at times as well this weekend, particularly Sunday morning. For Houston and points south and west, your best shot at storms may be Sunday, and as it stands this morning, that’s a low probability. Either way, no significant issues are expected this weekend.
Look for scattered showers and thunderstorms on Monday and especially Tuesday. Not everyone will see rain, but it will be our area’s best shot at storms since last week, so hopefully we can participate. By Wednesday, high pressure begins to reload over Texas, building toward the weekend. We will likely be back to hot and mostly dry by the end of next week, with daytime highs back in the 95 to 97 degree range, if not hotter.
Enjoy the holiday weekend, and please stay safe.
