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.
