Pollution watch Tuesday, cool front Tuesday night

HOUSTON, Texas (KTRK) -- You may come across brief, light showers overnight as a jet stream disturbance rolls through. It should move away before sunrise, clearing out the sky again for Tuesday.

Temperatures will bottom out in the low 50s, then the sun will warm highs into the low 80s. An Ozone Pollution Watch is in effect for the afternoon, so those with lung and heart conditions may consider limiting time outside between 2 p.m. to 7 p.m.

A stronger cool front will push through Houston Tuesday night, setting the stage for a cold and breezy Wednesday morning.

How cold will it get behind Tuesday night's front, and will it bring us any rain?
Temperatures will drop into the 40s Wednesday morning with wind chill factors possibly into the 30s. You will definitely want your jacket! If you were hoping for rain, sorry. This front will have almost no moisture to work with, so it should pass through dry.

So when will we have another opportunity for rain?
A small rain chance will return Thursday as Gulf moisture rushes in ahead of another cool front. That front will arrive either Friday night or Saturday morning, and that's when we'll have our next best chance for scattered showers and thunderstorms. Right now we have the rain chance Friday at 70%. Some of those storms could be strong, especially north of Houston.

How does the weekend look?
The rain should clear out pretty early Saturday, leaving us with lower humidity and lots of sunshine for the rest of the weekend. Temperatures will still manage to climb into the low 80s Saturday despite the north breeze behind the front. Sunday looks spectacular with lows in the 50s and highs in the 80s.
