You may be wondering when exactly you can plant this spring. Here are some general guidelines on freeze data.
For the short-term outlook, we dropped to 34 in the city with 20s and low 30s NW of Lubbock Tuesday morning. I think we could see at least one more freeze next week (April 13-April 19). Both the American GFS and the European models are pointing to cooler weather next week, pretty good way below average. It's too far out for anything certain, but if a light freeze is dangerous to what you're planting go ahead and wait. Avg. low temp this week is 43-44, next week it climbs to 47 by the end of the week.
Average final freeze of the season in Lubbock is April 10, based on about 90 years of data. Record for earliest final freeze is February 24, 2012; record for latest final freeze is May 8, 1938.
We did have some late freezes that caused damage last year. Here are average final freeze dates from the NWS Lubbock:
