The forecast for this week is fairly straightforward. We’ll see a pair of cool and sunny days to start out, followed by widespread rain showers on Wednesday, before a cool and sunny weekend. As the region has has a relatively dry winter, the mid-week rainfall should help with the abnormally dry conditions for much of the Houston region—Galveston, Chambers, and Orange counties excepted.
MLK Day
It is clear and cold this morning, with freezing conditions on the far northern reaches of the Houston metro area, in places such as Huntsville, and lows of about 40 degrees in the city itself. With light northerly winds today, continued cold air advection will offset a mostly sunny day, and keep high temperatures at about 60 degrees. Low temperatures tonight will likely be a few degrees colder than Sunday night due to very light winds. This should allow for a more widespread, light freeze over areas such as Montgomery County.

Tuesday
Another sunny, cool day with highs of around 60 degrees. By the late morning or afternoon, winds should shift around to come from the east, and along with building cloud cover this should help to moderate overnight temperatures, keeping them in the 40s for most of the region.
