Temperatures plummeted to 45 degrees early this morning here in Lafayette, breaking the old record of 46 set back in 1987. The cool air is expected to stick around again tonight, but tomorrow's record low of 39 will remain safe.
The very dry air mass allows the temperature to rise and fall easily, so cool mornings can turn rather mild with a sunny day. Usually when the air is humid, we'll see a 20 degree temperature swing between night and day. This air can produce temperature differences of 35 degrees or more! After tomorrow morning's forecast low of 48, we should rebound to 82 by Wednesday afternoon.
Relative humidity levels will hover between 20% and 30% this afternoon and tomorrow. With the current rainfall deficit of 12-16 inches across Acadiana, fire danger will be high again. A statewide burn ban remains in effect.
