A light freeze is expected across most of southeast Texas tonight. Lows will touch the 32 mark in Alvin, Pearland, Richmond, Sugarland and will flirt with the freezing mark in League City and the NASA area. Along and north of I-10 lows will range from 28 to 31 and may be a bit colder from Brenham to Huntsville to Livingston. Highs in the upper 50's Tuesday.
Also, there has been a tiny bit of Cedar pollen in the air the past two days. That my be why you are sneezing.
