A blustery front will blow into Houston on Monday, setting the stage for cold December weather this week. For now, we still expect milder conditions for Christmas week in Houston, with daytime highs possibly in the 70s by Christmas Day itself. There are obviously still nine days to go in the forecast, so details remain fuzzy.
Monday
Today is starting out warm and muggy, with patchy fog. Low temperatures at some locations in Houston on Monday did not fall below 70 degrees. But if you’re wondering whether this is September or December, Mother Nature will soon answer this question for you. A strong cold front will push through the region today, by mid-morning for areas northwest of Houston, around noon for downtown, and offshore by 4pm. We’ll see some light-to-moderate precipitation with the front, but accumulations probably will be less than one-quarter inch for most. Temperatures will drop 10 to 15 degrees, from the mid-70s, as the front passes, and the mercury will be in the 50s by this evening.

Tuesday
Skies will clear out on Tuesday as drier air moves into Houston. We’ll feel the drier air as winds gust to 25mph or higher. With temperatures only climbing into the mid-50s, this will be a brisk day before likely the coldest night of the week on Tuesday night. Some parts of the region north and west of downtown are likely to see a light freeze early on Wednesday.
Wednesday
Sunny, with a high in the upper 50s. After a chilly start, this day will feel warmer than Tuesday because the brisk northerly winds will have subsided.
