We've launched a new extreme weather product this week: Record Extremes. Recent, globally record-setting years have demanded a product that combines U.S. and international record extremes into one, easy to use interface. The Record Extremes page will give you the option to see U.S. and international records on a map and table. You can select any combination of record types at once, which, combined with the map, provides a interesting visual way to investigate record-setting events. The product uses data from three sources: (1) NOAA's National Climate Data Center, (2) Wunderground's U.S. records, and (3) Wunderground's International records.

The NCDC records begin in 1850 and include official NOAA record extreme events for ASOS and COOP weather stations in all 50 U.S. states as well as Puerto Rico, the Virgin Islands, and the Pacific Islands. In this database you can find records for maximum high temps, minimum high temps, maximum low temps, minimum high temps, snow, and precipitation on daily, monthly, and all-time scales.

The Wunderground extremes were compiled by our weather historian Christopher C. Burt. Chris monitors 300 stations across the U.S. for Record Extremes in maximum and minimum temperature, precipitation, and snow events. Most of these U.S. records go back to the end of the 19th century, though the oldest site in this database is Charleston, SC, where precipitation records started in 1737! Internationally, Chris monitors 150 countries worldwide for all-time record high temperatures and all-time record low temperatures. If you're interested in diving deeper into extreme weather in the U.S. and abroad, Chris's book Extreme Weather is an excellent resource.



Figure 1. All-time snow records broken during the Groundhog Day Blizzard of 2011. These records were found by selecting NCDC as the source, a start date of 2011-01-31, an end date of 2011-02-02, "maximum snowfall," and "all-time."


We built the Record Extremes product to make it easy to find specific records you're looking for, or just browse the records in general.

Check records that were set on a specific date
You can check on records that were set yesterday, for example, by setting the calendar to yesterday's date, and selecting all the record variables and types that you're interested in.

Explore all records set in a certain time range
2011 was a record-setting year for the U.S., and most of the records were high maximum temp and high minimum temps. To see all of these warm records that were set last year, select "NCDC" as the source, 2011-01-01 as the start date and 2011-12-31 as the end date. Select Maximum High Temp and Maximum Low Temp in weather variables, and select all-time in the record type.

View current standing international records in the Wunderground database
Select either the Wunderground International records, and instead of choosing a date range, select "Show current standing records." This will bring up all standing records in the database for whatever record variable and type you select. Whereas we've collected every record ever set or broken from NCDC, the Wunderground records are always the current, standing record, whenever it was set. As you move your map around the globe, you'll see each country's all-time maximum high temp and all-time maximum low temp.

Filter your table results
Looking for a specific location or record within your search results? Use the "Filter Results" option in the table to narrow down your search.

Let us know what you think!

Folks im telling you, El Nino is coming and this hurricane season will be a bust, 6-8 storms MAX, mostly fish storms. Just spoke with the folks at NWS Melbourne about this. Trust the models, they are always right!!!

2011 pacific season had eleven storms, ten hurricanes and six major hurricanes. 2011 was a la nina/neutral year which usually increase hurricane activity in the atlantic and reducing activity in the pacific. Despite the low number of storms in the eastern pacific, the pacific hurricane season was very active in terms of number of hurricanes and major hurricanes. We never be able to fully predict the exact number of storms and impact a season will have on the lives of people and i''m sure most americans remember 1992.

I know but hardly any rain is the forecast there for a while. S TX however could get some good rains this weekend but it appears this high is wanting build up over TX again based on some of the long range models. We really need to see consistant rain to dig out of 25" to 30" deficits. The good thing is if El-Nino does appear which it looks like it will then that could be very good news for TX down the road.


Still can see the Pacific flow moving over TX by the high clouds

I have noticed that overall the forecasts for the next 2 days is highly varied for the SE US.
In Tampa, for example, forecasts have been swinging as wide as 0 to 50%.Any ideas on this?


It will depend if we see a large cluster of storms develop over the FL Panhandle tomorrow AM because if they do form then we could see another MCS moving ESE. If we do then we could have a scenario like yesterday but again to early to get a feel for what tomorrow will bring as these spring thunderstorm complexes can be hard to pin point. Bottomline it's a wait and see deal.

So far so good.....It would have been a more serious event if the surface low tapped into a richer moisture source, and those strong westerlies will keep strong tornadoes from forming..Still cant rule out a few f-0 or f-1,s.

The 30% line for damaging wind gusts has been extended southward into central TN.

Still not seeing any activity in the risk area, is this an event that goes from nothing to everything near dusk?

I'm not buying into the El Nino thing yet, last time you all cryed that (December) we turned straight back down into La Nina, I'm still looking for a Neutral year. As pointed out already, the Atlantic is warmer than normal so if we do get El Nino it could be one of the rare active El Nino years.


We'll be closing in on neutral soon. We will have to watch to see if we go straight to El-Nino over the next couple of months. El-Nino is coming and this one could very well be strong. Equatorial Pacific waters have warmed 1.5 to 2 degrees since 1/18/2012. That is impressive!

Extent is back below the 2007 line, but not by much.

It leveled off this year, so it's more because 2007 kept rising a bit.

Should be interesting to see how long the plateau is maintained and whether there will be any more gains, or may it just starts falling off from here.

Look at the variable sea surface temperatures of the tropical pacific over the past three years
2010 was warmer than this year and last. Prooves my point we really cant tell at this time just based off of SST's. 2010 turned out to become a La Nina.

Destablization is having a hard time despite sunny skies in the Ohio valley but alabama mississipi and tennessee are destaabilizing nicely.
Unfortunately drier are is overlapped with the destabilization(i wonder what effect the dry air is having) so severe threat may decrease more across some areas
however it has warmed into the 60s across kentucky, S Indiana, and S Ohio.
A cloud mass is approaching and thickening from the west.
Cumulus is beginning to pop up acros Arkansas and SE Missouri S of the cloud mass.
A strong jet can be observed across MS and AL from the west, possibly responsible for bringing in drier air.
The situation bears monitoring for severe weather threat areas.

Well, if you still believe that the Fukushima accident is a light one and trust what TepCo and the government are saying, then all these posts about the Fukushima Nuclear crisis are Sensational stuff...

But you can make your own research from Enenews, fukushima-diary.com, fairewinds.com, province.com, reports from Arnie Gundersen (check out the many videos in Youtube from this engineer). For me, this is not sensational stuff, but just the tip of the iceberg.... and it's going to be news for a long time to come....

No one said it was not a bad accident. Yes, it will be news for a long time. Bad info is still bad info.

Quoting StormTracker2K:


We'll yesterday we weren't shaded in anything and we had a MCS raging across C FL. Given the fact that temps may approach 90 tomorrow coupled with 70 degree dewpoints could spell trouble for the same areas that got hit yesterday. Bottomline we will just have to wait and see how this evolves tomorrow.



Well here's the deal, the main driving force behind strong and severe thunderstorms ahead of a cold front is upper support. When you remove that upper support cold fronts don't really much left to show.


Yesterday they had a 30 to 40% chance of showers and maybe a thunderstorm in those areas, not a squall line consistently of massive storm cells to 40,000 ft with tons of lighting, wind, and very heavy rain.


For whatever reason upper level systems not associated with cold fronts tend to be down played around here. Ive seen many times where a forecast involving a low chance of showers turns into numerous strong thunderstorms.


Ive seen that happen in the summer are here in Central Florida too, sometimes you'll see the typical 40 to 50% chance of storms all the way through the week but an occasional upper disturbance will sweep through bringing widespread development of strong thunderstorms and widespread heavy rain, when we get them they seem to come by surprise with very little emphasis of them in the forecast. It seems the affects of upper disturbances are given a lot more respect further north then down here lol.

Gulf looks a good 0.5 to 1C above last year same day.

NW Caribbean has fewer cold spots than last year, actually about 1C to 1.5C hotter across the board compared to last year.

Edit:

On closer inspection, parts of the west-central Gulf must be at least 2C warmer than last year...

If we have an El Nino, it will probably be weak. The warm water in the Eastern Pacific is no very deep so at this time it will only support a weak Nino.
How deep is February E Pac warm water normally? It's just getting warmed up -yes?

I find that to be unrealistic. Tokyo is well to the south of Fukushima. Given the dominant weather patterns in the area I find it hard to believe that that much contamination made it that far south, even if there were a massive plums of radioactive materials.That's not to say that there isn't any contamination. But the story doesn't make a lot of sense.



Quoting Mochizuki San - fukushima-diary.com

It s just human to think western Japan is safe outside of Fukushima is safe. It s just an imaginary boarder of human, has nothing to do with radiation. Radiation doesn t think, oh I 9m getting out of Fukushima, shall stop here or should I get to Tokyo by Train or car.
Look at the world map. Japan is such a tiny island. Everywhere is the same. and now they re distributing the radioactive debris to all over Japan, to share the pain , which is so typical for Japanese, and all the food is contaminated. Cars, people, train, they are all contaminated and move around in Japan. There is no safe place in Japan. That s why I got out of there.
There are 4 main islands, Honshu, Hokkaiso, Shikoku, and Kyushu. but they are so close that you can even drive by car. They are all the same.
Mr. Koide from Kyoto university said, old people have to eat contaminated food because they have responsibility for nuclear, and it s the responsibility of future generation to accept radiation.
I dare to say no. I won t accept anything except for completely 0Bq/kg. I have no reason to eat radiation. I completely refuse to be involved in their fantasy world like Kamikaze. I really think all of them should leave Japan soon as possible.


------------------------------------------------- ----

Add to human activity the many unaccounted natural cycles like pollen that propagates by wind and insects, winter snow meltdown waters that go down stream and carry radiation and many other factors that we aren't aware off, not living there....
