A cold front moving through the Rockies now has grabbed hold of 'some' of the arctic air that's been lurking in northwest Canada for a while now. This front comes through tonight and will drop temps into the mid 30's Thursday morning in Houston. Huntsville, Jacksonville and other northern counties may see a light freeze tomorrow morning. Winds will gust out of the north at 20-25mph.
The coldest air will settle in Friday and Saturday mornings with lows in the mid to upper 20's Friday morning and upper 20's to near 30 Saturday morning. The pipes should be ok with these temps but protect the people, pets, and plants. Expect freezing temps for 6-9 hours Friday morning.
Light snow is expected during the Texans game on Sunday in Baltimore with temps in the low 30's. How sweet it is!
