Airmass Change
During the last 24 hours the Arctic airmass left as a Pacific airmass streamed in. This change occurred due to a broad area of west to northwest winds across the Plains. A series of storm systems (Clippers) are tracking southeast across the Midwest. On the west side of them we have west winds, blowing downslope from the high Plains (see surface map below from Saturday afternoon). This downslope causes the air to warm as it is forced to lower elevations. It now appears this airmass will dominate the middle of the country the next 5-7 days. So, watch for re-freezing at night and have plenty of window washer fluid.

Hi - Nice little snowfall - most I've seen at Blue Springs (9.5-10.5") since I moved here in Dec 2000.
The GFS (lastest run) shows the NW flow continuing, except that through 384 hours, I don't see a sign of a major buckling that would transport the North Pole out of the Northern Territories of Canada, such as occurred next week. Also, no major shots of energy to spin up in Colorado or Wyoming (like the last). It is interesting to note that Nov 15th and Dec 7th episodes were examples, I believe, of this sort of system. I wonder whether the next possible episode will occur approximately 3-4 weeks from now, or will another potential event occur earlier. I favor my 3-4 week theory, but then again... I only base this on the continuing pattern, and the timing between the two similar events.
Later,
Dog
Storm Dog,
The weather pattern is much more energetic and wild than I thought it would be. I think we are in for quite a ride with, perhaps, a lot of snow this winter.

HEY,
Was just looking at the GFS model and the 72 and 78 model run looks like so precip would it be rain or snow in KC if its not over doing it
DANIEL:
Right now it looks like a chance of rain late Tuesday and Tuesday night. If the cold air gets here soon enough, we could see some flakes mixing in by Wednesday morning. We'll keep you posted.

I thought it was rather strange that the temperature outside is close to 45 right now 8:54PM 12/11/05 yet there seems to already be refreezing on the parking lot of the apartment complex I live in. How is that possible? I'm thinking it is because the water is runoff from the snow at the top of the parking lot but you would think the air temperature would keep it from freezing.
Chad,
We do NOT have refreezing tonight. It just appears that there is ice. The ice that existed likely has a layer of rain on it and it is slippery, but the ice is from before. It has to be!
