After a spike in humidity since Tuesday, more refreshing weather will filter into Southeast Texas today. That will set the stage for what should be a pretty quiet weekend.
Today & Weekend
The cold front discussed this week will finally slide through here today. Humidity should still be a bit high this morning, and areas of fog around the region will lift. As the afternoon wears on, we’ll see humidity drop. By later today, dewpoints drop into the mid 60s in most of Southeast Texas.
High temperatures today will top off near 90 degrees, so it won’t exactly be suddenly beautiful. Saturday will still be a tinge humid, but high temperatures should be a couple degrees cooler.
Houston’s forecast remains on track, with another day or so of humidity before a front brings drier and cooler air in for the weekend.
One more almost summer-like day lies ahead for Houston with highs near 90 degrees. The ample atmospheric moisture also means we’ll have one more scattered shot at rainfall, which much of the region really needs now after a very dry September and almost no rain in October. Alas rain chances are probably only 20 to 30 percent, perhaps a little bit higher for western areas of the region. Lows tonight will again be warm and sticky.
We’ll see another warm day on Friday, with mostly sunny skies, but drier air will begin to filter into the area along with a cool front later in the day. Houston won’t see an immediate cool down, but conditions will be nicer by the evening hours, and the front will be more apparent come the weekend. Rain chances are near zero with the front.
Saturday and Sunday
Temperatures have been trending a little warmer for the weekend, but conditions still should be pretty nice for the region. Expect highs in the mid- to upper-80s, with drier air under sunny skies, and lows in the mid-60s, a bit warmer along the coast and cooler up north.
Welcome back to sticky weather. Lows this morning have only fallen into the upper 70s across the Houston area, and relative humidity is near 100 percent. Expect a few more days of this before some relief this weekend and early next week.
Wednesday and Thursday
We’re going to continue to see late-summer like conditions as southeast winds bring a warm, moist flow into the region from the Gulf of Mexico. Highs should climb to about 90 degrees, or maybe a tick warmer, with lows in the 70s. The more difficult question is how widespread the rain is. The region will have enough atmospheric moisture to produce showers, but there’s no real forcing mechanism. So I’d anticipate scattered showers both days, primarily during the afternoon hours and most likely along the coast.
A front should arrive in Houston later on Friday, but the day will still be warm in advance of its passage, with highs around 90 degrees. Expect a dry passage with little or, most likely, no rain. Drier air should allow low temperatures late on Friday night to fall into the upper 60s.
Saturday through Monday
It will take some time for the cooler air to work its way into Houston, but we should see more pleasant conditions by Saturday, and especially Sunday and Monday. Highs should fall back into the low- to mid-80s, with low humidity. Low temperatures will probably bottom out on Monday morning, in the upper 50s for inland areas, and low 60s closer to the coast.
The forecast for Hurricane Matthew, with 125 mph winds, continues to grow more concerning for Florida on Friday and into the weekend. The European model, in particular, has shown the potential for Matthew to strike or significantly graze Florida’s space coast, including the Kennedy Space Center. Already there are mandatory evacuation orders for Brevard County, and the hurricane may pose a significant threat to iconic structures at the space center.
Here are key messages from the National Hurricane Center with regard to the storm.
The last vestiges of drier air will move out of the region today, as a more southerly flow reestablishes control over the region’s weather. This is to be expected in October, of course, as Houston is caught between the warmth of the Gulf of Mexico, and periodic cool fronts arrive to bring relief from the humidity. During this work week the humidity will win.
Today through Thursday
Although moisture will return to the area, we’re not going to see the kind of conditions that promote rising air and therefore widespread showers and thunderstorms. While I expect to see some scattered storms, with slightly better chances along the coast, I wouldn’t count on much rain this week (Certainly less than 1 inch, and probably no rain for a lot of the metro area). That is too bad, because a lot of lawns need it. As for temperatures, we’re looking at highs around 90 degrees, with sticky lows in the mid-70s. Not particularly pleasant, but at least these temperatures will be transient.
