Cool weather, precipitation expected early next week; perhaps even — SNOW

Low pressures are also referred to as cyclones. In the middle latitudes of the Northern Hemisphere, mid-latitude cyclones are what we see on a weather map as a low pressure often with a cold front and warm front attached to it.

By the early part of next week, we have a cut-off low in the jetstream flow that will be moving in through southern Kansas.

As this cut-off low moves in, it will produce widespread precipitation near and northeast of its location. That puts the eastern side of Kansas in a very favorable area for precipitation.

Low pressure will develop at the surface to our south, further enhancing our north winds and ushering in some chilly weather at the surface, with much of the area holding in the 30s during the daytime Monday into Monday night.

Even though surface temperatures will likely be a couple of degrees above freezing, you won't have to go too far up into the atmosphere to get into sub-freezing conditions.(see the 850mb temperature map below where we'll be well below 0C/32F at that level)

Of course, slight changes in the track could bring in slight cooler or warmer air into the system, but what is so interesting right now is that the precipitation has been consistently showing up at fairly heavy across Northeast Kansas. In addition to that, the air beneath the clouds will be mostly below freezing until the last couple hundred feet near the ground. Big question will be: Will the precipitation have time to melt once it hits that slightly warmer air right at the ground or will parts of the area see some slushy flakes by Monday?

We'll be watching this one throughout the weekend very closely.

Whoa! Cyclones and snow?! Now what do you think about the weather guys, SP and Jeff? Are you hooked yet? And you thought the weather was boring.....

What will tomorrow bring? Dust storms and a tsunami? A blizzard with volcanic ash? Frog rain and an earthquake? I bet you guys are placing bets over a cold one right now.

This was actually pretty cool and useful.

My Predictions:

First scientists in India will discover an inevitable heating of the earth's core. Barack Obama ages dramatically to look like Danny Glover. John Cusak will take his children to Yellowstone where he'll discover a secret government project and meet Woody Harrelson. They'll discuss the impending end of days over Pabst Blue Ribbon Beer.. California sinks into the Pacific and Cusak drives a car through buildings to escape what millions of others fail to survive. And then - well, you know the rest... SP

SP~ Your predictions are amazing! You should write that up into a screenplay--I bet Hollywood would bite.

Hollywood would never be so shallow as to go with such alarmist crap.

In 2 or 3 years? Maybe then. ;)
