Drizzle & Fog

On this Good Friday, we're not really seeing GOOD weather. It's another rainy, foggy start! As the main storm works south of KC today, we stay with a chance of light rain or drizzle through the early afternoon. While we will dry out later in the day, we won't see much in the way of sunshine. Combine the clouds with cooler air moving in, and temperatures will not climb at all today! Highs will be in the lower 40s.

We're STILL watching the weekend storm. Look how close it is to us! Below is the GFS model for Sunday morning.

This is a look at the 500 mb vorticity. The yellow/orange areas you see are areas of greater vorticity. An eddy of vorticity spins like a low pressure--counterclockwise. This counterclockwise spin-up causes the air to rise downwind from the vorticity maximum. That rising air can form clouds and precipitation... if there is enough moisture.

And in this case, the "vort max" is JUST too far south to bring us any precipitation... but it is CLOSE!! Check out the GFS surface map and precipitation forecast:

We are RIGHT on the edge of this storm. Any further track north and we would be getting rain or snow. We will keep an eye on it, and Gary will have an update tonight!

There is a big warm-up next week... hang in there!
