While Tuesday will still be quite warm, with readings near 80 degrees F commonplace around southeastern Texas, changes are coming. A strong storm and cold front will push Arctic air rapidly southward. Thunderstorms could be quite intense, but likely will be out of the local picture by midnight (while tormenting the Old South and Ohio Valley). And even though the brunt of the bitter air will target the Midwest and Northeast, the chill will most certainly reach Houston in the early hours of January 30. The intrusion of colder air will prove transient. But for the time the "Norther" visits, frost and freeze potential may reach as far as Brazoria and Galveston counties.
A slow moderation process should get underway on Thursday, with the next series of cold air masses staying above 35 N Latitude. A weak cold frontal passage on Saturday may set off a few showers, but most of the weekend looks pretty nice with afternoon high temperatures in the 60s (F).
