the uk considers it a severe weather event and when i click on severe weather link on this site dense fog is shown they also say severe weather overlay with fog....so to me they consider it severe also
Or lets look at dew, it got my shoes wet!
True -not relevant in the moment, but true nonetheless. What I have managed to do is to get you and yoboi arguing (debating) on the same side against me. Reminds me of the consequences of interfering in a domestic disturbance. Don't let me be your killjoy. Monomania away!
that stuff is slippery... it probably kills more people in the states every year than fog!
Can you have severe fog? Yes.
So you can have fog as severe weather...
The Sixth International Conference on the Comprehensive Management of Coastal Areas will be held next May in the eastern city of Santiago de Cuba, which was most devastated by Sandy late last month, said the report, quoting Dr. Ofelia Perez, director of the Center for Multidisciplinary Studies on Coastal Areas (Cemzoc) of the University of Oriente.
The conference will be "a bright opportunity to study the complex circumstances associated to the course of the devastating cyclone in the region," said Perez.
He added that the main issue to be discussed during the meeting will be the integration for the sustainability of coastal ecosystems against climate change.
Perez said that experts from Mexico, Venezuela, Canada, Colombia, Uruguay, Spain, France and Brazil have expressed their interest in attending the conference, which will also cover social, health and environment studies linked to global warming.
Hurricane Sandy, which was considered "historic" by the local meteorologists, hit eastern Cuba on Oct. 25, devastating the city of Santiago de Cuba and leaving 11 people dead.
Over 130,000 houses collapsed in the hurricane disaster, which also caused economic losses of more than 100 million U.S. dollars for the island nation.
Uncovering the lessons of Sandy
...Also, we now know that an untold number of New York City firefighters and policemen stayed in their homes near the water, only to end up leaving in the middle of the storm in a nightmare evacuation... lashing family members together to hang on through the raging water. These are people that understand that really bad crap happens in the world. You'd think that an NYC firefighter, if anybody, would have taken action to protect his family if he understood that the ocean was going to come surging through the house. That was exactly the forecast, but that, obviously, did not come through in the messaging.

And eyeballing two images remains a poor way to identify trends for snow cover, as well...
yoboi,
Want you to know I see what you mean about the dropdown menu for "Severe weather" on Wu. The menu even includes hurricanes. The "U.S. severe alert map" seems to include all the advisories issued by NWS.
Here's a wu radar map from the Fort Polk NWS radar. When I clicked "Show Severe" it made an opaque white color over counties that have a "Winter Weather Statement" in effect. Below this map is the Winter Weather Statement for one of those areas.
Seems to me what this discussion has been about is different meanings of the word "Severe" to different bloggers, different websites, different types of mass media in different parts of the world.. As I said this morning, to me "Severe Weather" is thunderstorm related. I think (edit) also includes anything for which a watch or warning can be issued - e.g. fire, winter, flood. At wu, apparently something as simple as danger to tender vegetation applies. (And I do appreciate it when my NWS office issues those advisories so I know when to bring outdoor plants in.)
This is another example of how the meteorological community, including media mets, could make some changes, set worldwide standards, whatever. Kinda like naming storms. Don't be arbitrary. Give us some criteria that make sense and communicate more clearly to the general public. The way this website's severe weather link reads, severe could be an EF5 tornado or simply what's gonna kill your aloe if you leave it on the front porch. I think it's wrong to include an advisory like this on a radar map link meant to depict "Severe Weather." Maybe wu could rethink that and use a different click spot for everything except watches and warnings. Or not.

Freeze Warning
Statement as of 9:35 PM CST on November 24, 2012
... Freeze warning now in effect until 8 am CST Sunday...
* event... Canadian high pressure will continue to dominate the
four state region tonight with the center of the surface high
just to the east. Mostly clear skies and near calm winds will
allow for minimum temperatures to drop near or just below
freezing across most of the region on Sunday morning.
* Timing... freezing temperatures are expected late tonight
through around sunrise on Sunday morning.
* Impact... tender vegetation will be susceptible to cold related
damage. Additionally... pet owners may need to take precautions
to protect outdoor pets.
Precautionary/preparedness actions...
A freeze warning means sub-freezing temperatures are imminent or
highly likely. These conditions will kill crops and other
sensitive vegetation.
ADD: Nov 25. Crops, this could be a "severe" situation. Froma damage point of view, extended drought sure is.
How long does this go on for? it seems like you guys have been dealing with for some time now.
It's still feast or famine with a high anchored on Greenland.
you must be quite pleased with yourself, Mr. bappit.
;-}
It's that time of year for us. Will end around April.
William at support has written to say that the problem is with me and my failure to clear my browser caches. I pointed him to one section of 100 posts in which 14 separate people were complaining of exactly the same error message in all manner of browsers (cleared and not) and from all over the world. I haven't heard anything back since, and the problem is not fixed. If you want some action on the matter, I suggest you also write in.

I didn't even think of Frogger..lol.
I was taken with how the Kelvin waves have been dying sooner & farther west through time.
Oops! I tripped over the power cable to the WU's router. ... I'll get it. ...... Better? ... Oops! I need to flush the router's dns cache too. .... Be right back.
End of December the BOM is expecting a jump of the MJO which will kick off the NAMS.
Actually, the next apocalypse will happen in 2038. More precisely, 03:14:07 UTC on Tuesday, 19 January 2038. This is when internal clocks of 32 bit OS's will run out, flipping back to 1/1/1970.
Well, it's not really an apocalypse, but many a nerd and geek will sigh in nostalgia at the passing of that date. :)
Grothar, you need to keep better track of your toys.
Do you remember what happened when you lost the Ark of The Covenant? It took 4000 years for some guy in a dusty leather jacket to find the damn thing again. And even when he found it, he had to fight off a bunch of Nazis for it. The thing ended up melting people, so the government locked it up in warehouse where you won't be able to play with it anymore.
And don't get me started on Noah's Ark. How you manage to lose a giant wooden ship capable of holding two of every animal on Earth I'll never know. And poor Noah wouldn't even have needed to build it in the first place if you had made sure your sink faucet was turned off.

Tropical Cyclone Advisory #7
FORTE TEMPETE TROPICALE BOLDWIN (03-20122013)
10:30 AM RET November 25 2012
=======================================
At 6:00 AM UTC, Severe Tropical Storm Boldwin (992 hPa) located at 14.5S 73.2E has 10 minute sustained winds of 50 knots with gusts of 70 knots. The cyclone is reported as moving west southwest at 8 knots.
Dvorak Intensity: T3.0/3.5/W1.0/12 HRS
Storm Force Winds
==================
20 NM radius from the center extending up to 25 NM in the southern semi-circle
Gale Force Winds
===============
30 NM radius from the center extending up to 50 NM in the southwestern quadrant and up to 70 NM in the southeastern quadrant
Near Gale Force Winds
======================
60 NM radius from the center, extending up to 90 NM in the southwestern quadrant and up to 120 NM in the southeastern quadrant
Forecast and Intensity
=======================
24 HRS: 15.3S 71.2E - 35 knots (Tempête Tropicale Modérée)
48 HRS: 16.8S 67.5E - 30 knots (Depression Tropicale)
72 HRS: 22.5S 66.9E - Depression Se Comblant
Additional Information
========================
In the south of the upper level ridge axis, vertical wind shear keeps on increasing near the center of Boldwin.
The low level circulation center has been re-localized northern and is now under the northwestern edge of the deep convective main cluster (SSMIS F18 0309 AM UTC and F17 0049 AM UTC).
This convective activity mainly exists in the southeastern quadrant but remains strong, well sustained by a rather good poleward upper level divergence.
Wind shear is expected to keeps on increasing slowly over the next 12 hours then more sharply as the system will undergo the influence of an approaching upper level trough.
System is therefore expected to keeps on weakening within the next 36 hours as it tracks west southwestwards under the steering influence of the subtropical high pressures. On and after tau 48 system should track towards a polar trough transiting in its south, and turn southwards and then south southeastward.
Think it's quite likely that my clock will have run out long before then. But ya never know. In any case, there is at least one nice thing about being an old, retired UNIX guru... At least I won't be sittin' in the hot seat for that one the way I was for Y2K. :)
Ya seem stuck on an image. Ya off yer meds or something?

Wettest summer here in Scotland for 100 years, and it just keeps falling.
The usual path of the jet stream has altered in recent years, bringing unusual and extreme weather to many regions. The most extreme effects have been the record Russian heat wave of 2010 and the record Pakistani floods that year.
The jet stream is weakening, probably due to the 'arctic dipole', which itself is probably being caused by the record Arctic ocean ice melt. This causes its meandering 'loops' to move further south.
The jet stream is emerging as an early 'joker in the pack' in climate change, causing unexpected changes to regional weather patterns.

The weather in Puerto Rico will be very good this week with plenty of sun and cooler temperatures.
As we near the end of the month, the 7-day forecast holds a couple of slim chances for a few drops in the bucket – but a completely dry November is starting to look like a bleak possibility.
If we do end the month with 0.00″ of rain at Camp Mabry, this will only be the 4th such occurrence since records began in 1856, and the first time in over a century:
Camp Mabry’s Driest Novembers:
November 1861 – 0.00″
November 1894 – 0.00″
November 1897 – 0.00″
November 2012
"On November 11, 1911 the most extreme cold front in U.S. meteorological records swept quickly across the Great Plains and Midwest. Kansas City, Missouri fell from 76° to 11° in 12 hours. Oklahoma City fell from 83° to 17° and Springfield, Missouri from 80° to 13°. In all three cases the cities recorded both their record high and record low temperature on November 11th."
Burt's blog posts are always a great read, and this one is no exception. If you can tear yourself away from the riveting "Fog is severe weather!" arguments, go have a look... ;-)
