The Dallas area will be under the gun for a freeze threat March 25-26 thanks to a big “blob” of chilly Canadian air moving through north Texas under rising pressures. The high pressure cell also brings strong northerly winds for Sunday with highs expected to remain in the 50s to near 60. Given wind speeds of 20 to 30 mph, spring will definitely be on hold.
The air mass is very dry and skies and expected to be clear Monday and Tuesday mornings, so this sets the stage for a light freeze. The most likely freeze locations will be along and north of I-20, but those areas that don’t receive a freeze will probably get within a degree or two.
The record lows for DFW International Airport on these days are as follows:
March 25…26 (1955)
March 26…23 (1955)
These records appear safe, but some upper 20s are expected over the northern half of the Metroplex.
The average last freeze date for the Metroplex is March 13, so this is a couple of weeks late, but far from the record latest freeze, and in fact it won’t even make the top 10 latest list. The latest freeze on record for DFW took place on April 13, 1957.
