All that talk with that last system and hardly a drop of rain at my place far NW OKC! What do I have to do to get rainfall around here? Mowed the lawn and everything and notta!
Visible sat pic from around 9:40 this morning showing the cold front coming through OKC. Back in the day a front coming through was known as FROPA short for frontal passage.
Here's the weather map from around the same time from the fine folks over at the Oklahoma Mesonet. Look closely at the wind barbs. You can see the direction of the wind barbs shifting from SW to NW from around Ponca City to OKC to Lawton...that's the cold front! That's the demarkation line between warm, muggy air and cooler drier air. You can see the temps and the dew point temps drop behind the front as winds shift to the northwest. This is weather 101 and I love it!
As the front pushes southeast into the warmer more humid air eventually by later this afternoon thunderstorms will develop along and ahead of the front. By the time the thunderstorms form the front should be over in far eastern and southeastern Oklahoma. Here' s the risk for severe weather today from the Severe Storms Prediction Center in Norman, Oklahoma. It's a Slight Risk of severe weather with the main threats large hail, damaging winds, lightning, locally heavy rainfall. The tornado threat is low but not zero! In fact within the Slight Risk the area most likely to get severe weather is highlighted by the orange showing the Enhanced Risk. This is indicating that any thunderstorms that get established out ahead of the cold front could possibly produce some higher end severe weather including a few tornadoes. The thunderstorms right along the front are more likely to produce high winds and some hail.
One of our short range computer models from this morning has a good handle on the weather. This is the surface map forecast by around 6pm this evening. You can see the cold front to our east and a relatively cool high pressure system coming south into Oklahoma. That big blue H is the center of the high pressure area that will settle down on Oklahoma tonight. So expect a fantastic day today behind the cold front with gusty northwest winds, comfy temps and dry air. Of course the fire danger is up again today behind the front so watch the outdoor burning! Tonight, a fabulous night with clear skies, light winds and cool temps!
Rain chances will be on the increase this weekend especially by late Sunday and Monday. There are many indications for heavy rainfall on Monday but I'm not yet ready to go there. Been there done that. This drought has its grip on me....
