Severe Weather Update For OK Friday

A blue northern type cold front will arrive on Friday bringing colder and fresh air to the state. Ahead of the front, gulf moisture should make a return starting Wednesday.

This front will be a line of battle for thunderstorm development as it pushes in. Expect storms to fire near I-44 and across eastern and southern OK. An inch of rainfall is possible.

The timing on the front is still in question. If the front moves through around lunch time, the threat for severe weather will be lower for the OKC metro. If the front arrives late day, the threat will be higher.

It is my experience that cold fronts in this pattern usually do not produce tornadoes, but mainly wind, heavy downpours and lightning, sometimes damaging hail. The front may undercut the moisture making the storms elevated. This negates the tornado threat as well.
