NEW 1 Inch Hail Criteria

No change is being made to the severe thunderstorm warning criterion of wind gusts equal to or in excess of 58 miles per hour.

Severe Weather is expected tonight. We still plan to have the meeting and the board meeting tonight. Participation is voluntary and the phone conference is also an option so we are leaving it up to our members/guest as to whether they come to the meeting or not.
I would put the chances on a call out in the >75% category. The watch may be out earlier, but I think the main threat will be between 9 PM and 6 AM…probably getting REAL serious around midnight. If the probabilities continue, expect a PWO (Public Weather Outlook) for overnight tornadoes…
