Major Changes Are Showing Up In The Weather Pattern

Good morning bloggers,

There is a hot pattern continuing as the old LRC continues to dominate our weather across the North America.  There are some major changes showing up, however.  Fall begins Saturday night, and this is when the sun sets at the North Pole. The new LRC likely truly begins setting up around the time this happens around 8:54 PM Saturday night, and right on cue some interesting changes being to open our minds to these changes.  Take a look at the pattern forming by next Tuesday:


We are likely 75% old and 25% new by mid-next week.  The jet stream is strengthening in response to an increasing temperature contract from the North Pole to the Equator.  As colder air masses develop, the jet stream will continue to strengthen and the new pattern will evolve. For Kansas City, I do not believe it is possible to have a worse pattern than the one we just experienced this past year. It was certainly entertaining for us weather enthusiasts, and ridiculously frustrating. The frustrations were off the charts bad, in my opinion.  It has been close to 4 years since KC has had even 3″ of snow in one storm. Think about this alone. So, we have experienced around four straight very bad patterns. Just because we are “due” for a good pattern, a much more exciting one, does not mean it will happen. I just will argue it can’t be worse than this past year.

What you are seeing above in this 500 mb forecast map from last nights GFS model run, the new experimental GFS model, which I am not impressed with so far by the way, is a strengthening jet stream. And, there is a trough developing and swinging positively tilted out of the Rocky Mountains out over the plains and upper midwest.  This next map shows the surface forecast:


A rather strong frontal system is approaching KC next Tuesday.  This will likely drop our lows all the way down to near 40 degrees next week.  And, there is a good chance of thunderstorms or a cold rain around Tuesday-Wednesday. Let’s see how this looks on the next few model runs.  In the mean time we have this next system to look forward to on Thursday night:

Will those thunderstorms survive and arrive in our area early Friday morning? We will be going in-depth on 41 Action News tonight on all of these changes.  It will heat up into the 90s again these next two days before we drop on Friday. It will likely be a dry weekend. Go Chiefs on Sunday!
