A recipe for frost or even a light freeze is taking shape over Texoma for the morning of Tuesday, April 5th.
The Red River Valley region normally sees its last freeze between mid-March on the Texas side to late March on the Oklahoma side. While a bit late this year, a frost or light freeze on the 5th will probably not set a record, but neither is it good news for tender vegetation now in full bloom.
Wind speeds will drop to just a few mph overnight; the air is very dry with dewpoints in the 20s, and skies will be clear. This allow for efficient radiational cooling, so expect a cold start to Tuesday with frost and perhaps a light freeze. A widespread freeze is not expected, but mid to upper 20s could be observed in those typically colder locations of Texoma.
Plants should be protected if they are susceptible to frost damage.
Much warmer weather returns quickly and highs should be in the 80s by mid-week.
This is very likely the last frost/freeze threat until October for us.
