The National Weather Service, Norman Forecast Office’s “Hazardous Weather Outlook”, issued at 12:31 p.m. Sunday, stated, “Thunderstorms are likely today and especially tonight. No severe weather is expected through tonight.”
The discussion said, “A stationary front across southeast Oklahoma into central Texas will slowly lift north as a warm front today into tonight. Meanwhile, moisture will continue to spread north across the region through tonight. The combination of increasing moisture and some instability will allow for mainly elevated showers and storms to occur today into tonight. Better storm chances will be overnight as an increasing low level jet and approaching mid level disturbance enhance lift across the area, allowing for scattered to numerous thunderstorms.
“Limited instability will hamper the potential for any storms to become severe through tonight. However, a few storms may be strong through tonight producing small hail and gusty winds. Otherwise, heavy rain and cloud to ground lightning will be the main concerns with any thunderstorm.”
Probability of thunderstorms occurring in the NWS Norman County Warning Area: 100 percent.
Probability of severe storms if storms occur: 10 percent.
Other hazardous weather: “Locally heavy rainfall may occur later today and tonight. This could cause flooding in a few locations.”
