Tropical moisture surges in Wednesday to bring up the rain chance
HOUSTON, Texas (KTRK) -- A surge of tropical moisture blows into Houston overnight, and this will bring up rain chances for the next several days.
Temperatures overnight will only cool off into the mid 70s with widespread clouds developing ahead of sunrise. As temperatures warm back into the low 80s, scattered showers and thunderstorms will develop ahead of the noon hour. These showers and thunderstorms will be capable of producing heavy rainfall, wind gusts over 40 mph, and frequent cloud-to-ground lightning. The highest rain chances will occur between 10 a.m. to 4 p.m. Rain chances drop off north and west of Houston, where high temperatures could again reach toward 90. Where it does storm, temperatures will peak in the low-to-mid 80s then cool off into the 70s when the rain begins.
How much rain could we get?
We expect totals of 1-3" to be fairly common through the weekend. Any storm that develops could drop a quick inch of rain. The highest rain chances are Thursday and Saturday, both at 70%. That's because a cool front will blow through on Thursday, which will momentarily push the tropical moisture into the Gulf of Mexico. Then on Saturday, that front will lift back northward with all the tropical moisture pushing back through Houston.
What kind of weather can we expect for trick or 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 the time the candy is filling up bags and buckets. The ground will likely be wet even if the sky is dry at that time. Temperatures will likely be rain-cooled in the 70s.
When can we expect temperatures to really cool off again?
Our confidence is growing that our next strong cold front will arrive on Wednesday or Thursday of next week. This front should bring temperatures down to seasonal levels with highs in the 70s and lows in the 50s. It's even possible we catch a morning or two in the 40s.
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.
