Here's the latest from NWS OKC on last Wednesday's severe weather event in central Oklahoma. There was a small area of EF-2 damage found in Moore, OK from the survey team. EF-2 tornado has winds up to 135 mph!
Interesting weather tonight. Light south winds are transporting milder and much more humid air north from northern Texas into central Oklahoma. The dew point temp is the temp of saturation. In other words when the actual temp drops to the dew point temp the humidity is 100% saturated! This is why I call the dew point temp the temp of saturation. Generally, the higher the dew point temp the higher the humidity. Looking at the dew point temp map might seem boring to you, but it's a good way to show where the low level moisture is.
Here are some Oklahoma Mesonet maps this evening showing the dew points, the light south winds and the 3 hour dew point temp change. The 3 hour dew point temp change map is really really important because it shows where the moisture is going! Notice we have light south winds blowing or advecting the higher dew points north into central Oklahoma. Here in Oklahoma county the dew points are rising into the 50s. With clear skies temps will gradually fall to near the dew point temps in central and southeastern Oklahoma and if the temp drops to the dew point temp the relative humidity is 100% and you get fog. There is also a chance for some showers across mainly southern Oklahoma overnight. If you were counting I just said dew point 12 times!
I know this is geeky weather stuff and more than a bit confusing but this is a weather blog, right? That's what I thought.
So if you see fog by morning or perhaps a few showers now you'll know why.
Again, these maps are courtesy of the Oklahoma Mesonet.
BTW latest 00z weather data is coming in and from my first glance it appears to me that I will NOT be making any changes or updates to the severe weather risk maps I posted in my last weather blog. If anything, confidence is LOWER on thunderstorm chances both in terms of location and intensity over the next few days. In a nut shell, The best chance is in western Oklahoma Wednesday and then shifting into eastern and southern Oklahoma Thursday. But again, way too early to call and like a said if anything lower confidence than earlier update. Go figure!
