Green or Global?

Okay, I know I get some oddball comments for this post, but this opinion is shared by many of us who have degrees in atmospheric sciences. I don't know if I go to the extreme that John Coleman does but it certainly is a good read. Mr. Coleman is the founder of the weather channel, so he has some impressive credentials. Here is his take on global warming.

Closed low moves out

A much better looking weather picture for the next several days. We have been dealing with a couple of anomalies which keep clouds and showers around for quite a while. First let's talk about a closed low or cut off low. Here is the definition from the National Weather Service:

Cutoff Low

A closed low which has become completely displaced (cut off) from basic westerly current, and moves independently of that current. Cutoff lows may remain nearly stationary for days, or on occasion may move westward opposite to the prevailing flow aloft (i.e., retrogression).

"Cutoff low" and "closed low" often are used interchangeably to describe low pressure centers aloft. However, not all closed lows are completely removed from the influence of the basic westerlies. Therefore, the recommended usage of the terms is to reserve the use of "cutoff low" only to those closed lows which clearly are detached completely from the westerlies.

so basically we talking about low pressure that doesn't have jet stream winds to push it along and unlike most weather systems which move through within a day and the weather improves quickly the next day. This part of the country is plagued with these kinds of low pressure areas and they get stuck in the doldrums of very little movement in upper air winds of the jet stream.

Temperatures Tumble to Begin Week

A very chilly start to the day but southwest winds are going to bring in some warmer air with highs moving into the 50s. But the biggest problem for the next two days is going to be the rain. Showers will continue to be pushed northward by stubborn low pressure which will move gradually to the east over the next 36 to 48 hours. Most of the next two day will be kept in the clouds as well.

You can see the low parked across the area and that's the main factor for today and tomorrow. You can also see the QPF which is bringing in about another .50 to 75" of rainfall through Tuesday afternoon.

Mild air will finally be moving in across the area today as a smaller 'bubble' of high pressure will set up in the Great Lakes Region
You can see on this surface map that there is a lot going on around us. Low pressure to our west and east, but finally some high pressure blocking any cloud cover and changing very little over the next 3 days. That's about all you can hope for right now as we have a very fast moving jet stream. Okay, so I know this is going to be a little mind expanding and I apologize for it in advance, but I wanted to show you the 200 mb chart. This is the place where the jet stream resides. You can see by the legend that we do have 100 knot winds pushing weather systems through very quickly. Right now that jet is driving the fastest moving air to the north. High pressure is also a factor in pushing this jet stream north. There's always been a debate in meteorology on whether the jet stream steers high and low pressure or low and high pressure steer the jet stream.
