Two charts, because spring and fall answer different questions: in spring, the chance that a frost still comes after a date; in fall, the chance that the first frost has already come before it. NOAA publishes these odds from 10% to 90%, so the lines stop there. ◆ marks the actual date in each recent year.

What these dates mean

April 4 is the cautious spring date for Texarkana; with only a 10 % chance of a light frost later, it lets gardeners set out tender crops. By contrast, February 24 carries a 90 % chance of a light frost later, making an earlier planting a gamble.

The 50 % light-frost dates are March 15 and November 17; they mark the point where frost is equally likely to have occurred or not. The 50 % hard-frost dates are March 1 and December 1, showing the median timing for temperatures that drop to 28 °F. A hard frost at 28 °F can damage plants that would survive a 32 °F light frost, so it matters more.

November 1 is the cautious fall date, with only a 10 % chance that a light frost has arrived earlier, allowing gardeners to finish harvesting tender crops. A later date such as December 4 involves a 90 % chance of a frost earlier, turning late harvest plans into a gamble.

How to read the probabilities

The dates are probabilities from 30 years of weather, not a forecast for this year.

  • Spring: "10% after April 4" means that in about one spring out of ten a frost still happens after that date. The 90% date is the earliest: a frost after it happens in most years.
  • Fall: "10% before November 1" means that in about one fall out of ten the first frost arrives before that date.
  • 50% is the typical date: half of the years are earlier, half are later.
  • A light frost (32°F) damages tender plants; a hard frost (28°F) also stops most hardy vegetables.
