What a difference a 20° drop in the dew point makes, huh? This morning when I was on the air, our dew points were in the 70s.
Now, here at 4:00 in the afternoon, these are the dew point values:
If you’ve been outside at all, you can tell a big difference. Despite the fact our temps are in the middle 80s right now, it just *feels* so much cooler out there. Down to our South, in portions of Southern Kansas, they wound up 20-plus degrees cooler today thanks to rain.
The rain and clouds are now pushing into Oklahoma, helping to cool them down.
Southern Kansas and Oklahoma were in the triples yesterday, now today in the middle 80s. The advancing cold front has helped to generate the rain and usher in that nicer air. This was the surface map from the HPC earlier this afternoon.
You can see the big area of High pressure in the Northern Plains and Southern Canada. If you look closely at the map, you can see temperatures up there are in the 60s….at the end of July! Incredible.
This trend of cooler air advancing South will continue for a few more days. So what’s the deal? Another big dip in the jet stream.
By tomorrow, a large “trough” (as we call it) will sit over the MidWest area, even reaching down into parts of the South. Meanwhile, a high amplitude ridge will reside over the Western portion of the United States. Those who live in that area are going to roast. Areas like Spokane, Washington will see highs this week near 99°. They average temperature there for this time of year is 86°.
Meanwhile, to the East, in place like Detroit where the typical high this time of year is 83°, they will enjoy temperatures in the low 70s for the next few days.
Going all the way into Wednesday, I do not see much change in the pattern:
Notice the jet gets a bit closer to the area by Wednesday. This could open the door for a few showers and t-storms. But once again, we’ve seen this before; recall a couple weeks ago. At this time I’m not terribly optimistic for meaningful rain/storms, just based on the models. But if the overall pattern does repeat, there could be meaningful rain VERY close to the area on Wednesday.
My reward for working the marathon shift this week is that I get three days off. And I tell you what, these next three days are going to be great to get outside.
