HOUSTON, Texas (KTRK) -- Once our cloud deck moves out, temperatures will fall quickly through the 30s this evening, then below freezing after midnight. Areas outside Harris county will fall into the upper 20s. We're forecasting a low of 30 degrees in the city of Houston. Patchy, dense fog is expected to form over our northern counties and that could cause a few issues.
It's rare for fog and freezing temps to exist at the same time in southeast. When it happens, you have to be looking out for a very thin layer of ice to form on bridges and overpasses. The most likely place for that to happen is over our northern counties. No matter where you are, if you see fog in your area overnight, slow down before moving over bridges and overpasses.
Saturday and Sunday will both bring cold mornings but milder afternoons. Saturday starts off with the light freeze then clears the 50 degree mark under a mostly sunny sky. Sunday morning could feature a coating of frost, but it now looks a weak weather disturbance will blow in to kick up the clouds and bring a 40% chance for showers. This could keep the low above frost territory, and the added clouds likely keep the high again in the 50s.
At this time we expect next week to be seasonable with no freezes for Houston. MLK Day weekend will feature a warm up into the 70s, but then a stronger cold front is expected to arrive, and that could bring back freezing temperatures after MLK Day.
