We are heading back to being mired in a weather pattern that is generally low impact (aside from some fog) but also fairly obnoxious: Lots of clouds, cold fronts that will shift temperatures in a big way depending on where they’re situated, and plenty of rain chances but ultimately not a lot of rain accumulation. Let’s dive in.
Today
Areas of fog, locally dense, have developed this morning, and there is a Dense Fog Advisory through 9 AM for most of the area. Give yourself a couple extra minutes out the door today. As fog lifts, expect a good deal of cloud cover this morning, giving way to some partial afternoon sunshine at times. High temperatures today will be contingent on sunshine. With a lot of sun, we could make a run for 80° in spots, particularly west of I-45. With clouds hanging on, expect upper-70s in most places. Some fog may roll back into coastal communities later this afternoon.
Saturday
The forecast for tomorrow is tricky. The first in a series of cold fronts will get down to about US-59 in the morning.

Using the image above (which shows dewpoints instead of air temperatures), you can see the cold front is conveniently right along US-59. This is from the NAM model, which is probably the most aggressive of the models in bringing this front south. In fact, this may even be a smidge too far south and east. But I want to show you how sharp a cutoff this is between very warm humid and potentially cooler and drier.
The front will likely make limited progress south and may even begin to retreat a bit back to the north in the afternoon. Ahead of the front, we will see areas of dense fog along the coast or in the bays once again for much of tomorrow. Temperatures will likely be in the 70s to perhaps near 80° again. North and west of Houston closer to the front in the afternoon, look for mid-70s. There is a small degree of uncertainty tomorrow. If the front is able to be aggressive and dives southeast enough, some areas north or west of US-59 may only see highs in the 60s Saturday.
The good news is that rain chances look limited on Saturday. There may be a few showers or sprinkles along the coast, but otherwise, it just looks mostly cloudy tomorrow (foggy along the coast).
