USA Severe Cold weather ...Swirling 'Polar Vortex' Over Northern US

[Sinny]

Can't find the previous thread I posted to, however to expand on my previous question: "Are we sure it's all natural?..

Yesterday in Birmingham, UK, we had a rain storm, followed by a snow storm, followed by bright sunshine.

Yea, if that's normal, I'll eat my socks.

4 Hour time frame.

As far as I understand it, we cannot really know it, as the weather we get is always a reaction to something that happened before, somewhere (mostly to the west in the northern hemisphere and to the east in the southern hemisphere), some time before.

Yea, if that's normal, I'll eat my socks.

I don't know if it's normal or not, but I don't see any reason for it not to be possible.
If I'm not mistaken, snow occurs when rain passes a layer of air that is below the freezing point and doesn't get heat enough to melt until it reaches the ground, so it's perfectly possible that rain is followed by snow.

Sunshine after rain or snow is also normal, specially if we are talking about cumulus clouds, that, although big, have lots of space between them.

But this is just in theory, as I have never seen snow in my life.

I appreciate the theory of it all..But in reality it was bizarre.

The USA continues with its cold spells...

Yesterday Hail stones & snow....in the UK

Today 100 MPH winds.

I was watching a TV program earlier that showed the storms , clouds and wind patterns coming across the Atlantic which was said to be due to the Gulf or jet stream....It seemed quite severe and may be some of worst weather patterns that I have ever seen to be coming towards the UK..

The UK has severe flooding around the coast and around the River areas from the Midlands to the South Coast...

The UK Government are being asked what are they doing about the Flooded homes..

One has to question is this natural or created by the Globalists weather machines..

OR The Giant Sunspots that have recently occurred..

Or is it Mercury going retrograde or the other planets effecting our weather !

One weather expert says its down to weather conditions created on the other side of the World where it has been very hot and this has created a lot of humidity to go into the atmosphere that in turn that moisture has been carried by winds across the planet ! or something like that ...

Yes, that's how it works.

The weather the UK got today is the result of how the weather was in the middle of the north Atlantic two days ago, that was the result of how the weather was in the north of the US/Canada two days before, etc., etc.

Ok guys, more of the same - something different: Poor man's polar vortex to make shocking summer return in eastern U.S. next week

This an interesting article is talking about unseasonably chilly air is headed for parts of the northern and northeastern U.S at the height of summer early next week" - 10 to 30 degrees below average! That is kinda significant, even if it is not real cold! Daily record temps are expected in some ares of the Plains and Great Lakes.

I continue to wonder about when the real entrance into the long term cooling period will begin........or are we already in its beginning??

Exerpt from Washington Post.com - "What's behind this unusual winter weather pattern primed for the dog days of summer?  A lot of it is simply chance (randomness), but Weather Underground's meteorologist Jeff Masters says Japan's typhoon Neoguri is playing a role in the pattern's evolving configuration:

....the large and powerful nature of this storm has set in motion a chain-reaction set of events that will dramatically alter the path of the jet stream and affect weather patterns across the entire Northern Hemisphere next week. Neoguri will cause an acceleration of the North Pacific jet stream, causing a large amount of warm, moist tropical air to push over the North Pacific. This will amplify a trough low pressure over Alaska, causing a ripple effect in the jet stream over western North America, where a strong ridge of high pressure will develop, and over the Midwestern U.S., where a strong trough of low pressure will form.

What amazes me most about the pattern is not so much the forecast temperatures, but the uncanny similarities in the weather patterns over North America seen in both the heart of winter and heart of summer. All of the same features (refer to the map at the top of this post)  apparent in January are on the map in mid-July: low pressure over the Aleutians (blue shading), a large hot ridge (yellow and red shading) over the western U.S., the huge cold low or vortex over the Great Lakes (blue and green shading), and then the ridge over northeast Canada (yellow and red shading).

It's not at all clear what this means or what, if anything, it portends".

Yesterday it was a mild and very tolerable 70 some degrees. Later at night it was a clear moon lit night with low humidity and 48 degrees. I was walking in the moon light wearing my jacket and hat. Lovely evening with stars and moonshine.

well the part that caught my eye was this

Poor man's polar vortex approaches parts of U.S.

By Jason Samenow
   The Washington Post

Call it the ghost of the polar vortex, the polar-vortex sequel or the polar vortex's revenge. Meteorological purists may tell you it's not a polar vortex at all.

However you choose to refer to the looming weather pattern, unseasonably chilly air is headed for parts of the northern and northeastern United States at the height of summer early next week.

Bearing a haunting resemblance to January's brutally cold weather pattern, a deep pool of cool air from the Gulf of Alaska will plunge into the Great Lakes early next week and then ooze toward the East Coast.

Of course, this is July, not January, so temperatures forecast to be roughly 10 to 30 degrees below average won't have quite the same effect.

But make no mistake, in parts of the Great Lakes and Upper Midwest getting dealt the chilliest air, hoodies and jeans will be required. Highs in this region could well get stuck in the 50s and 60s — especially where there is considerable cloud cover.

Wednesday morning's lows might drop into the 40s over a large part of the central United States. Remember, this is July!

The heart of the chilly air mass will probably just skirt the East Coast, but temperatures are likely to be about 10 degrees below normal. Highs could struggle to reach 80 in Washington on Tuesday and Wednesday, with widespread lows in the 50s (even 40s in the mountains).

Note that, as with any extended forecast, there is some uncertainty here. If the cool air mass loses some punch, highs might still reach 80 to 85 around the District of Columbia, with lows in the 60s rather than the 50s.

The pattern might last only a few days but will probably set some records, especially around the Plains and Great Lakes — where water temperatures are still depressed from the frigid winter in which ice remained on Lake Superior into June.

What's behind this unusual winter weather pattern primed for the dog days of summer? A lot of it is simply chance (randomness), but Weather Underground meteorologist Jeff Masters says Japan's typhoon Neoguri is playing a role in the pattern's evolving configuration:

"The large and powerful nature of this storm has set in motion a chain-reaction set of events that will dramatically alter the path of the jet stream and affect weather patterns across the entire Northern Hemisphere next week.

"Neoguri will cause an acceleration of the North Pacific jet stream, causing a large amount of warm, moist tropical air to push over the North Pacific. This will amplify a trough of low pressure over Alaska, causing a ripple effect in the jet stream over western North America, where a strong ridge of high pressure will develop, and over the Midwestern United States, where a strong trough of low pressure will form."

All the same features apparent in January are on the map in mid-July: low pressure over the Aleutians, a large hot ridge over the western United States, the huge cold low or vortex over the Great Lakes, and then the ridge over northeastern Canada.

It's not at all clear what this means or what, if anything, it portends. Weather patterns cycling through a certain circulation regime can repeat (and we've seen this pattern multiple times since November and December), but with El Niño forecast to develop, the global configuration of weather systems is likely to change.

As news of this cool-air episode breaks, you might notice meteorologists bickering over whether this is a "polar vortex" event or not. For their part, several National Weather Service offices are using the term.

But Larry Cosgrove, an energy meteorologist, says that while the looming cool air mass is "admittedly impressive," calling it a polar vortex is hogwash.

"It's insane," Cosgrove wrote on his Facebook page. "Poor wording combined with misunderstanding of the term make a mockery out of synoptic meteorology."

Cosgrove's argument is that the air mass doesn't meet the "polar vortex" standard — its pressure isn't low enough and the air isn't sufficiently cold and truly Arctic in origin (i.e. not below freezing at 5,000 feet). "[On] TWO counts we fail to reach the standard for calling such an upper low a vortex," he said.

The middle road might be the best one: Call it a "poor man's polar vortex."

According to the weather man here, a polar plunge will blow into green bay this tuesday with temps like 66 degrees for july when it should be 80 something. It was 48 degrees a few nights ago and probably be just as low when the plunge hits.

It's been chilly here in ND, highs of the day either not breaking 70 or just barely above.  It's a good 10 to 15 degrees cooloer than normal temps this time of year.
