The northern half of Houston is seeing freezing conditions again this morning, but temperatures will soon warm up today. For the first time in 2018, the region should see highs reach the 50 degree mark—still about 15 degrees below normal for this time of year. The warming trend will continue through the weekend before a moderately strong cool front arrives.
Thursday and Friday
Amazingly, the warming trend doesn’t mean we’re entirely out of the woods for some frozen precipitation. Thursday will see mostly sunny skies, and a cool but pleasant day. Overnight lows should fall into the mid- to upper-30s tonight, and a weak atmospheric disturbance could bring some clouds tonight and early Friday morning, and with this some very spotty sleet or cold rain is possible to the west and southwest of Houston.

However, since the ground will remain above freezing we don’t anticipate any effects and, indeed, I don’t think most people will see anything. Friday itself should be a great day, with sunny skies and highs in the mid-50s.
