The NBC Action News Winter Forecast will be issued at 10 PM on November 24th!
Good morning bloggers,
IT'S FRIDAY! A cold front will move through this morning. This is not an Arctic cold front as the air is much more Pacific in origin, but it will produce a lot of wind later today and tonight as the pressure gradient tightens. Many locations are still near 50 degrees this morning and with some sunshine and a downsloping northwest wind I am expecting temperatures to rise a degree or two today despite this cold front coming through. There is a lot of cold air aloft that will surge over us today. When the cold air moves over the relatively warmer air near the surface, combined with a developing deep trough aloft, some showers will likely form. By tonight it will be cold enough for snow to be mixed in with these showers but they will be rather sparse. Will we have our first snowflakes of the season during the next 24 hours? The chance is very slim!
The jet stream is strengthening today. Look below at the forecast map valid at 6 PM tonight:

Notice how Kansas City is at the base of the upper level trough. The 140 to 165 mph core of the jet stream is to our west causing the trough to deepen. The key on the left shows the numbers in knots. 100 knots is equivalent to around 115 mph. This trough literally is developing today, deeping, digging, and forming right over eastern Kansas and western Missouri. It will rapidly shift off to the east producing a storm that will quickly move through the eastern states and out of here. As the heights rise and the jet stream lifts to our northeast we will have the advertised dramatic warm up on Sunday. But, before this happens we may have just enough ingredients for snow showers tonight or early on Saturday. Let's all monitor this potential tonight and I will be tracking the developing showers this evening on NBC Action News.
The snowflake contest will not end for quite some time. We had nearly 6,000 entries in the contest. Each day around 50-75 people are eliminated. There are still aound 5,000 people left in the contest and there is still no indication of our first inch of snow happening anytime soon. The contest ends when one inch of snow falls at the KSHB-TV studios as measured by Brett, Jeremy, Jeff, or myself.
Have a great Friday! We are on a rollercoaster ride of temperatures for a while. We will be tracking the rapid warm and cold changes in the forecast today and tonight on NBC Action News.
