Good early morning NBC Action Weather Bloggers,
A Dense Fog Advisory is in effect this morning as a warm front pushes our way. And, a Major Winter Storm may be developing within 24 hours. It is taking aim on our viewing area. Look below at the 6 AM surface map. The temperatures are already jumping before sunrise. How far they will rise today will depend on how far the warm front moves north. It could easily get into the 60s today, especially south of I-70.

Do you see the warmer air? Look at the individual temperatures. The air temperature is the red number on the upper left portion of each observation. The dewpoint temperature is the green number underneath the red number. It is 70 degrees with dewpoints in the 60s over northeast Texas, and this is before sunrise. What does this tell us? It tells us that there is an extremely moist air mass ready to be the fuel for this Tuesday storm system.
The last few model runs have trended towards a wet and major winter storm in our area on Tuesday and Tuesday night. The 06z GFS shows an upper low just southwest of Amarillo, TX on Tuesday. If this happens, the moisture will be pulled farther west and we will end up with a very wet day on Tuesday. At the same time, this storm will develop a surface low on the front moving through. Cold air will be pushing in while the storm is moving across. This will create significant accumulations of snow, but the targeted area right now is just northwest of Kansas City as you can see in the blue circle, that I drew in. The red area, including the KC metro area, is right on the edge of this storm system, as I see it right now. It would only take a slight shift south and we would all be in it Tuesday night.

We will be monitoring this situation closely. The NWS has already issued a Winter Storm Watch for much of northwest Missouri. I will have an update later this morning as we analyze the new data. And, Brett Anthony will have the latest trends on our newscast at 11 AM (Our new Midday hour long newscast). I am on Newsradio 980 KMBZ, and once the new data starts coming out I will have an update on the radio after 8 AM.
Have a great start to your week.
Gary
