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!

its really weird here on the gulf coast, there is a real stiff breeze blowing westward at ground level, yet the clouds and the low in the gulf, are steadily moving eastward towards daytona..never saw this before


I am about 25 miles south of the track and it hasn't rained here all day.
While I'm not a race fan, I know this is an important event for a lot of people and feel bad if they cannot make it happen today.

Here's an update from Nascar.com:
4:02 p.m. ET

As updates go, it's pretty much what you might have expected. Track drying is still under way, it has stopped raining and there's hope of getting the race in tonight. However, there is also another big rain cell headed in the general direction of the facility.

3:57 p.m. ET

The skies over the track are looking much more encouraging than at most any other point today!

3:45 p.m. ET

Fifteen minutes until an expected update from NASCAR.

3:33 p.m. ET

Steve O'Donnell is tweeting up a storm today. His latest tweet says that there's a window on the radar, but adds, "We'll need the green blob behind it to blow north!" Also, dryers are on the track.

3:29 p.m. ET

NASCAR official Steve O'Donnell, asked on Twitter if shortening the race is an option to get it in today, responds, "No, sir. If we start, we intend to run 500 (miles)."

The preliminary PRISM climate maps appear almost done for the month of July last year. The following below illustrates the departure from "average" for the conterminous lower 48 states for the month of July and August.

Thanks for the plots. Not questioning the data being plotted, but a glance at that seems to understate the ferocity of the heat in SE Texas for August--either that or God help the people north of here. There have never been so many days above 100 in a row for Houston. I think that heat is what killed so many trees here. I drove by Memorial Park in Houston recently and they have cut a lot. I was thinking the dead trees at least would be good for woodpeckers. They've suffered in the last 50 years or so from people cutting down dead trees (among other things).

Finally got around to looking at the Record Extreme web page on WU. (Hey, that's what this blog is about!)

I was surprised to see a lot of record minimum high temps in the southeast US on Feb. 24. The reason the minimum highs surprised me is because the page also shows a lot of records for maximum high temps for the same dayin the same general area. This is using the NCDC data. I don't have a map from Feb. 24 to check what was going on. Anyone know?

One nagging issue with the plots I see is that it seems that the records for a given category are not always posted in the same order when you check off different boxes. That can make the plot look different when (I assume) the same data is being plotted. That is annoying. Icons seem to over post each other in different orders.

For example on Feb. 24 if you only check maximum highs the plot looks one way. If you also check minimum lows (only one in the southeast US which looks bogus), the plot looks quite different. This can also happen if you change the date range to include days with no additional records for an area. Maximum highs in Arkansas for Feb. 24-25 look different from maximum highs in Arkansas for Feb. 24. The same data is posted in both cases I presume (no record highs in Arkansas for Feb. 25), but it looks different.

I am sad right now for a reason, my great-grandma is in the hospital with pneumonia, they think she might of had a heart attack.
If I can ask all of you one short thing, please pray for her.
This weekend has been good but hard.
Yesterday one of my aunts I never knew passed away.
Yesterday was my brother's birthday party.
Today my parents are/were supposed to come over today for my brother's birthday party at home.
So if I can ask you all one thing
I am going to ask you to pray for her.
She is in the hospital as of now and I really need these prayers for my great-grandma.
She might be old but she can recover from this troubling time with your prayers and consideration.
Thank you all for your very kind and sympathetic wishes and prayers.

prayers for you.

Not bad, a little on the paranoid end of the gullible-paranoia scale, but a healthy dose of paranoia is not necessarily always a bad thing-it's always better to err on the side on that side than to be too trusting of the "officials", distrust & verify- have you seen the Stanford/American Institute of Aeronautics and Astronautics Large Eddy Simulations of Persistent Aircraft Contrails white paper that concluded that chemtrails indeed do warm the atmosphere?


Aircraft consume much of their fuel at a cruise altitude near the tropopause,
1
where exhaust has a long
residence time and conditions are conducive to the formation of condensation trails (contrails). The impact of
contrails and related aviation-induced cloudiness on climate is highly uncertain. The most recent assessment
of the effect of aviation on global radiative forcing lists the level of scientific understanding as 'low' for linear
contrails and as 'very low' for induced cloudiness.
2
The range of estimates for these effects is large, and if
the upper end of the range was realized, it would be nearly double the other warming effects of aviation
http://www.stanford.edu/~anaiman/Publications/Nai man_ASM_2011.pdf

Estimates of some warming contributions
to radiative forcing by aviation during 2005 (Lee, et
al. 2009). Bars indicate median estimates, whiskers
indicate 90% likelihood ranges.

On another topic,look how bone dry West Africa is as a big drought has affected that part of the continent with many fires and starvation increasing. I bring this here because it will be interesting to see down the road if this drought continues limiting the number of Tropical Waves that emerge Africa,or things moist up and we see the normal train of waves.The red dots are fires raging.
