Coldest weather of the season heading into the United States this weekend. Houston will probably start feeling the impact by Sunday night. Another chance of measurable rain precedes the cold front on Sunday. A few thunderstorms and gusty winds are also likely as the colder Canadian air mass slides in.
Watch the latest reliable US model runs of this cold Canadian outbreak. Temperatures in the upper mid-west could fall into the -10 to -20 below zero range. Houstonians may also see a good run at the freezing mark especially in the Northern suburbs and parts of the metro area. This may be a good time to stock up on some ground cover for your garden, if you don't have some already.
Here's a loop of the chilly outbreak next week. The light blue shades of color are temperatures that are below 30 degrees while dark blue are below zero.
