HOUSTON, Texas (KTRK) — A surge of moisture is on the way to Houston, and this will bring us our best rain chances in over 5 weeks! In fact, the last time we had measurable rain at Houston’s Bush Intercontinental Airport was on September 24th.
Get ready for a very mild morning with temperatures Tuesday starting off in the low 70s, well above the average low of 56 degrees. Why will it be so warm? That’s because a strong Gulf breeze will blow in bringing back low clouds and plenty of Gulf moisture along with them. Despite the warm start to the day, temperatures will only warm about 15 degrees to make it back into the upper 80s. Isolated heavy rain showers are possible as the Gulf moisture increases throughout the day, but the rain chance will climb even more for Wednesday and Thursday.
How how do rain chances go this week, and how much rain could we get?
Rain chances look to peak at 70% on Halloween, with a secondary peak of 60% odds on Saturday. We recommend carrying an umbrella around as soon as Wednesday with the chance of heavy showers climbing to 40%. As for how much rain could fall, we expect totals of 1-2″ to be fairly common through the weekend.
What kind of weather can we expect for trick or a treat time on Halloween?
It will almost certainly be a humid Trick-or-Treat time this Halloween, but there is a fair chance the rain will occur earlier in the day and come to an end for most by Trick-or-Treat time. We still need another day to nail down the timing of the rain, but at a minimum prepare for the ground to be wet even if the sky is dry at that time. Temperatures will likely be rain-cooled in the 70s.
What are you tracking in the tropics?
There is now a region in the southwestern Caribbean that has 40% development odds over the next 7 days. While we’ll be keeping a close eye on this region for any storms, the general pattern over Texas and the Gulf should steer any potential storms away from us over the next two weeks.
