Severe weather reports so far today. Several rounds of thunderstorms during the day kept temps relatively cool limiting instability and over all severe weather potential but still a few tornadoes in Oklahoma!
The big story was another day with significant rainfall across a large portion of Oklahoma continuing to knock down the drought!
It's not over yet!!
We launch weather balloons up into the sky to get a snap shot of the atmosphere. This tells us what is going on at this exact moment at different levels in the atmosphere so that we can make a better prediction. The pic above is a snap shot of the upper level weather pattern from this evening. The observations from these balloons revealed an upper air trough over the rockies and this is the storm system responsible for all the heavy rainfall and severe weather over the past several days in the plains and also the heavy snow in the mountains.
Latest computer guidance continues to show this system as a slow mover from the rockies into the central plains next 24 hours. This means that it's not over yet for Oklahoma. That's right, another day of paying close attention to the weather. Another day to make sure you can get to the fraidy hole at a moments notice. I've got more rounds of thunderstorms in the forecast later tonight and through the morning hours tomorrow. Then another significant risk for severe weather and heavy rainfall across about the eastern half of Oklahoma Sunday afternoon / night into the wee hours Monday morning. Finally things start to dry out Monday afternoon!
Here's the brand new latest Day 1 severe weather risk for Sunday from the Severe Storms Prediction Center in Norman Oklahoma.
The Slight Risk area has been shifted back west slightly! I new this would happen.
As the upper trough of low pressure slides east a weak cold front will drop southeast from Kansas into Oklahoma approaching OKC Sunday afternoon. I think additional thunderstorms will develop along the front as it moves into central Oklahoma by Sunday evening.
The best chance for thunderstorms appears to be from near the I 35 zone and points east from there as the front slowly pushes southeast across eastern Oklahoma Sunday night. With the strong upper trough and strong wind fields there's at least a slight risk for severe weather with the main threats large hail, damaging winds, heavy rainfall and I can't rule out tornadoes.
However, just like Saturday, any on going rain and thunderstorms in the morning hours could cool off the atmosphere and limit the over all severe weather potential for Sunday afternoon / evening.
Bottom line Sunday will be another day we have to pay close attention to the weather, Once again it's a dual risk of severe thunderstorms and possible flash flooding rains.
