Fog Explained....
Good afternoon! (and it IS shaping up to be a good afternoon weather-wise!) The fog we started with this morning has burned off, and the sun is helping to warm our temperatures into the 60s, and it's still early!
Why did we see fog today? Well, we had all the ingredients:
*Clear skies
*Light winds
*Enough moisture.
What we experienced was ground fog, which is a form of radiation fog. This type of fog is relatively shallow, and it forms almost exclusively at night or near daybreak.
How it happens... the clear skies allow the heat of the day to radiate back out into the atmosphere... this cools the ground. THEN in turn, the ground cools the air just above it. When the air is cooled to its dew point (saturation) or cooler, fog forms!
Maybe you're wondering why fog is worse in those low-lying areas, and along the river. Well, fog often forms first in those lower spots because there tends to be more moisture there. Also, cool air is DENSE air, so it sinks to the lowest elevation. These two things promote fog formation... and fog can often be most dense in these low-lying regions!
But as the sun comes up and we get a little "mixing" thanks to our winds also coming up a bit... the fog burns off! Thus our sunny afternoon.
Still watching an approaching storm for Sunday night. The latest GFS run would give us a good chance of thunderstorms Sunday night into Monday morning. That is something we'll have to watch. Here is the latest GFS run for early Monday morning:

Right now it looks like we could see a break in the rain for Monday afternoon. Here is a look at the 1pm Monday GFS forecast:

Notice drier air working in behind the initial push of moisture. That may be good news for KC baseball fans! We will keep you posted! Meantime, enjoy today, tomorrow and most of Sunday. Ahead of the storm we will experience a beautiful couple of days!
Gary will be out at the Wheel of Fortune tonight, so I will be doing the 5 & 6pm weathercasts. He will be back for the 10pm show!

Dear Jamie,
Thanks for the simple explanation on "fog". I am copying and pasting some of the weather info and saving it to my "weather" file. You guys keep up the great work. I am transplant from So Cal and I really enjoy this time of year.

Gary,
Where do you get your toasted ravoli from, or do you make it yourself?

ANNE:
Toasted ravioli is one of my favorite foods! I don't make it myself, though... you can get it at any Italian restaurant!
