Wednesday mid-morning update...Arctic air spilling in!

Southerly winds last night warmed the are into the 30's and near 40 in Kansas City as I expected.

Yesterday evening, the storm was just entering Iowa, and moving quickly east south east. I thought by 7:00 AM Wednesday, it would be in northern Missouri, just near the Illinois border. The storm was just a bit further north right around the Missouri/Illinois/Iowa border. The cold front at 7:00 AM was pushing through north central Missouri.

Now, the front has pushed further south. Take a look at the surface map I drew below:

There may be a couple snow flurries and snow showers this morning.

Notice the front is already about to push into Oklahoma, and you can see the winds blasting in from the north between 20 and 40 mph. Notice, the 50 degrees in northern Oklahoma, and the -6 degrees in Iowa. That is a 56 degree difference!

The temperatures will crash all day today and into tonight. By 7:00 PM Wednesday, I am expecting below zero temperatures, and single digits to already be spilling in to the area. With winds blowing between 20 and 40 mph, windhill values will be between -5 and -25 degrees. I think we will bottom out Thursday morning with lows between 0 and -10 degrees.

This cold air will continue through Thursday as the strong high pressure settles in. Highs Thursday will be between 15 degrees to the south and 0 to 5 degrees to the north. Winds will continue to be breezy Thursday, and beging to calm later in the afternoon. They eventually switch out of the south Thursday night into Friday.

Lows Friday morning will be very cold...between 5 and -5 degrees, but the southerly winds will take over, and we will be in for a big temperature rise into the upper 30's and low 40's. The warm weather will continue through mid next week into the 40's, 50's, and possibly even upper 50's and low 60's for Tuesday.

Iwill have an update on the frigid temperatures tonight.
