Yep, it’s gonna get pretty durn cold in Houston

Good morning. The main news remains the potential for very cold weather in Houston during the coming seven to 10 days. While we still have questions about the details it is now time to begin considering preparations.

Also, it’s worth noting that very cold weather in February is far from unprecedented. Back in 1899, the city of Houston recorded consecutive days with low temperatures of 6 degrees on February 12 and 13. That means only six degrees of separation from a low of zero degrees.


As expected, moderate to dense fog has developed across the region this morning, with muggy conditions in the 60s. This fog may not dissipate until 9am or so for some areas. A front will sag into Houston today, and stall around 30 to 50 miles from the coast. Effectively, this means if if you live inland of Interstate 69, highs today may generally be in the 50s, but if you live south and closer to the coast, highs will be in the low 70s. Some scattered showers will be possible area-wide today. Overnight lows will be similarly dependent upon the extent of the front.

Conditions should be similar on Wednesday, with the front stalled out across Houston. Depending on where it’s hung up, you may see highs in 50s with drier air, versus highs in the 60s with more humidity.  Rain chances will be a bit higher, with perhaps a 40 percent chance of light to moderate showers.


One more day of divided temperatures, with warmer conditions along the coast, and cooler weather further inland. Rain chances will be that much higher as a stronger, Arctic front approaches, and pushes into Houston later on Thursday. Most areas should see between 0.5 to 1.5 inches of rainfall through Friday morning.

We’ll see a much colder day on Friday, with highs perhaps in the low 50s and partly sunny skies. Lows Friday night will drop to around 40 degrees.

Saturday and Sunday

A reinforcing shot of Arctic air looks set to move into the coastal region on Saturday, and this is what will likely set the stage for much colder weather early next week. Highs on Saturday may remain in the 40s, with lows dropping into the 30s for Houston, and 20s for inland areas well inland on Saturday night. Sunday may struggle to get out of the 30s, with lows Sunday night again likely below freezing for much of the metro area. Happy Valentine’s Day—this will not be the best of years for planning some sort of outdoor surprise!

Early next week

Quite frankly, we’re still struggling with how cold conditions will get during the Sunday through Tuesday period of next week as the models are really all over the place. Some ensemble members of the GFS suggest temperatures could reach their nadir on Tuesday morning, in the teens even in the city of Houston. This probably is too cold, but a widespread and potentially hard freeze does seem likely. It is time now to consider preparations for plants and pets, and if temperatures drop below about 25 degrees, external pipes. Please note the details of this medium-range forecast remain uncertain, and therefore will change. And when it comes to low temperatures like these, small changes matter.

  1. A bit of perspective – Saturday night in my home town the forecast low is -10F. That’s not the wind chill, either.
    Count your blessings.

  2. I know this may be a bit premature, but what would be, potentially, the most consecutive hours below 32F we could experience, on a per day basis? Trying to project a schedule of work to prevent damage.

  3. For all of those celebrating a cold snap like this, or comparing it to how cold it is where they came from, I remind you that Houston is not built for this weather. It is not Chicago. Pipes will burst, plants and animals will die. If it is like the two other seriously hard freezes I have experienced here in the last 10 years, I can only hope I avoid the thousands of dollars in water damage I experienced in those.

  4. One thing to keep in mind – if Houston gets the full blast of polar air (down into the low 20s/teens), there’s very little point to covering your plants. The air will be so cold and dry that little frost will be forming – it will be the air itself, not frost, doing the killing through freezing the water in the plants. You’ll need to bring inside anything you can, and just accept that you will need to replant whatever is less hardy.

    • After years of gardening here, I plan on cold snaps every few years to take the overgrown tropicals down to the roots. The perennials will come back, and if they don’t, I get to try something new.

  5. Considering I’ve already had a couple of mosquitos in the house during the past month, a hard freeze isn’t entirely unwelcomed.
