Frost possible overnight, arctic cold front brings hard freeze by MLK Day
HOUSTON, Texas (KTRK) -- Frost is possible overnight in Southeast Texas, but we are predicting a major arctic cold front arriving this weekend will now bring a hard freeze to Houston by MLK Day.
Temperatures tonight will drop into the 30s just about everywhere, and frost is possible generally north of I-10. High clouds will flow in from the southwest during the day as moisture increases ahead of our next rainmaker. Temperatures will peak in the mid-to-upper 50s.
When are we expecting rain chances this week?
Another rainy low pressure disturbance looks to blow through on Wednesday, and the impacts look to be similar to what we experienced on Sunday. We expect chilly showers under a cloudy sky with temperatures warming from the mid 40s to the low 50s on Wednesday. Another round of rain could impact us on Friday, but because this time it will be significantly warmer with temperatures in the 70s, thunderstorms will be possible. By Saturday we should be drying out with just a 20% chance for rain.
When is the arctic front arriving and what can we expect it to bring us?
A blast of arctic air looks to arrive sometime on Saturday, and that will bring significantly colder weather for Marathon Sunday and MLK Day. It's too soon to hammer down the details of just how cold it will get and whether or not there will be wintry precipitation, but at this time we are expecting the freeze line to move into Houston Sunday night, with lows in the 20s to follow for at least a couple of mornings. A hard, pipe-bursting freeze is on the table, and it will be cold enough for ice and snow if moisture overlaps with that cold air. Stay tuned as we sort out the details this week!
What can runners and spectators expect for the Chevron Houston Marathon on Sunday?
It's going to be a cold one! At this time we expect the start of the race to feature temperatures in the upper 30s along with a north wind up to 25 mph pushing the "feels like" temps into the upper 20s. It now looks like it will probably be dry with some sunshine breaking through to warm temperatures through the 40s during the race.
