Interesting weather set up this afternoon with classic warm front boundary cutting right across Oklahoma. Much cooler air to the north with temps 50s / 60s easterly winds while to the south of the front temps 60s / 70s with southeast winds and dew points well into the 60s to near 70!
Here's the surface weather observations from the Oklahoma Mesonet clearly showing the warm front boundary setting up over the south OKC Metro just south of Norman.
Pretty impressive temperature gradient across Oklahoma this afternoon!
There's a decent upper air disturbance ejecting out of the southern rockies and this will move over the southern plains this evening enhancing thunderstorms and rainfall potential through the evening hours.
Conditions will be favorable for significant severe weather including possible tornadoes and flash flooding along and south of the boundary while to the north widespread moderate to heavy rain and marginal severe weather appears possible.
The boundary could fluctuate some this evening before moving back southeast later tonight and Wednesday morning.
The map above shows where the greatest severe threat is this afternoon mainly just south of OKC especially down near the Red River with tornadoes possible.
This second map I posted from the Severe Storms Prediction Center highlights an area out west as the main upper air disturbance arrives later this evening the boundary could surge back north again with another round of severe weather and heavy rainfall possible as it tracks east tonight ending Wednesday morning.
Remember a Flash Flood Watch is up and running as well and flash flooding can be a real killer especially at night!
Here's the latest HRRR hi res weather computer run showing this system pushing east overnight and there will be a break in the rain Thursday into Friday before the next storm system approaches Oklahoma for this coming weekend.
Stay tuned to the weather folks!
