It’s snowing in Houston—or rather above Houston. By looking at the radar this morning we can see that snow is falling down to around 2,000 feet above the surface and then melting. This is not uniform, and I expect that a few areas around, and north of town this morning may see a few snowflakes or sleet. We don’t expect anything to stick, so it shouldn’t affect travel around the area. More of this wintry mix will be possible tonight—including the possibility of some real snow falling right along the coast.
We’re going to see one more dreary, winter day today as an upper-level storm system slowly moves through the area and off to the east. Rainfall accumulations won’t be a concern—we’re just seeing light to moderate precipitation—but the cold rain will add to an already cold day. Highs Thursday are unlikely to reach 50 degrees.
Things get interesting tonight, as temperatures are forecast to come down into the mid-30s in Houston. However, even as we’re cooling down this evening, precipitation should be ending from northwest to the southeast. This means for inland areas, likely north of Interstate 10, the rain may end before it gets cold enough to produce a wintry mix of snowflakes or sleet.
Likely, then, the best chance for a wintry mix will be closer to the coast, where precipitation will probably linger into Thursday night or early Friday morning. (As Matt explained in depth last night, such forecasts are very, very tricky. A lot of things have to go right to make snow in Houston). Our best guess is that coastal areas see some snowflakes later tonight, although kids may have to stay up fairly late to catch them. There’s the potential for some snow accumulations south of Houston, perhaps in Matagorda County, or well to the east of us in Southern Louisiana. Locally we don’t expect that, at least right now. Regardless of what falls from the sky, expect a very chilly night.

The rain finally ends on Friday morning for everyone, and skies begin to clear out. Still, it will be cold, with highs of only around 50 degrees. Expect another cold night, although not quite a cold as Thursday night.
Saturday and Sunday
As we’ve been suggesting for a while, the region will see a fine, sunny winter weekend, with high temperatures in the low 60s, and overnight lows down around 40 degrees—warmer along the coast and colder for inland areas.
Most of next week looks fine as well, with highs remaining generally in the low- to mid-60s, and virtually no chance of rain until Friday or Saturday. It remains too far out to take a look at potential weather for Christmas in Houston, but we’ll start taking a preliminary look next week.
