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!

That SW Flow is still bringing us the Rain..we had frontal passage earlier today and this is round 2.

May need to leave the mention of sprinkles in for the southern
half of the area for the evening. Chances of measurable
precipitation are rather low though. High pressure will briefly
build in at the surface. Shortwave moving eastward out of north
Mexico will approach the area Saturday evening while it weakens
moving into confluent middle-level flow. This will cause rain chances
to increase late Saturday afternoon and Saturday night.
Precipitation amounts will be rather low...under one tenth of an
inch in most places. Middle level flow will remain southwesterly
through the weekend. The front will remain close enough to the
coast for slight chances of precipitation to remain over the
coastal waters for much of the weekend. Guidance temperatures
through Saturday night are close and accepted. For Sunday and
Sunday night...trended to the warmer GFS solution. This will put
temperatures 5 to 10 degrees below normal through Sunday
morning...then close to normal through Monday. 35

The 2004 transit had already started during sunrise and was easy to see with binoculars. Yes I looked at the sun with binoculars right as the sun came up. Those eclipse projectors worked well too.

Fission Products in National Atmospheric Deposition Program Wet Deposition Samples Prior to and Following the Fukushima Dai-Ichi Nuclear Power Plant Incident, March 8 April 5, 2011
By Gregory A. Wetherbee, Timothy M. Debey, Mark A. Nilles, Christopher M.B. Lehmann, and David A. Gay


Radioactive isotopes I-131, Cs-134, or Cs-137, products of uranium fission, were measured at approximately 20 percent of 167 sampled National Atmospheric Deposition Program monitoring sites in North America (primarily in the contiguous United States and Alaska) after the Fukushima Dai-Ichi Nuclear Power Plant incident on March 12, 2011. Samples from the National Atmospheric Deposition Program were analyzed for the period of March 8 April 5, 2011. Calculated 1- or 2-week radionuclide deposition fluxes at 35 sites from Alaska to Vermont ranged from 0.47 to 5,100 Becquerels per square meter during the sampling period of March 15 April 5, 2011. No fission-product isotopes were measured in National Atmospheric Deposition Program samples obtained during March 8 15, 2011, prior to the arrival of contaminated air in North America.

I saw the last transit 8 years ago when the sun came up. They happen in pairs 8 years apart with gaps of over a century between pairs.


Cool..

I bought my Scope Xmas 1996, and it was a good tool for Comet Hale-Bopp in Spring of 97

Transits of Venus are among the rarest of predictable astronomical phenomena. They occur in a pattern that repeats every 243 years, with pairs of transits eight years apart separated by long gaps of 121.5 years and 105.5 years. The periodicity is a reflection of the fact that the orbital periods of Earth and Venus are close to 8:13 and 243:395 resonances.

Before 2004, the last pair of transits were in December 1874 and December 1882. The first of a pair of transits of Venus in the beginning of the 21st century took place on 8 June 2004 and the next will be on 6 June 2012. After 2012, subsequent transits of Venus will be in December 2117 and December 2125.

For the southern USA all seven of the brightest objects in the sky after the Sun will be visible 1 hour after sunset. The moon of course. And then these.

Yes, another severe weather threat will evolve across the Ohio Valley down into the Southeast as a strong low moves across the Northern plains. The limiting factor with this event appears to be moisture, which will be a little on the low side due to this afternoon's event.

I posted this on Facebook already, but for those of you I don't have added...

So after watching The Phantom Menace 3D today, I have to say, I don't understand the hate for either Jar Jar or Jake Lloyd. I mean yeah, the former was essentially pointless other than providing Sidious with executive authority to produce the clones, while the latter certainly was no child prodigy. But honestly, like with the Anakin/Padme romance in Episode II, neither of these characters are particularly movie-shattering. Like, they don't make it unwatchable.

In short, I understand the complaints, but don't sympathize with how clearly exaggerated they are.

i got rain, and some little bit o wind, but nothing to make me smile :/

Whats wednesday, another severe possibility?

NWS says for me:

Wednesday: A chance of showers. Cloudy, with a high near 71. chance of precipitation is 50%.

We tend to hide from people that ask if we are home because they usually ask us for money making a promise that there will be a perfect-for-tracking hurricane, and then it never comes.... Tread lightly young friend, hope youre young because if you're old I messed up but how should I know?!?!?

Falling raindrops produce friction as they drop through the atmosphere to the ground, and this dissipates the kinetic energy, converting it into diffuse heat.
...[that] kinetic energy dissipation rate...turns out to be on average 1.8 watts per square meter in the tropical regions between latitudes 30 degrees South and 30 degrees North. ...around the same as dissipation caused by turbulence in the atmosphere, such as in storms and trade winds. ...rain-induced dissipation is stronger for continental convection than maritime convection.

...changes in hydrologic (water) cycles could affect the amount of kinetic energy dissipated in the atmosphere and affect the amount of energy remaining to produce winds. Hydrologic cycles are changing rapidly, and if these changes and increased evaporation result in greater rainfall (and rain falling from a greater height, as it does when the atmosphere is warmer), this would dissipate more kinetic energy and could thus result in slightly weaker air circulation by winds.

Any changes are unlikely to affect large storm systems such as hurricanes, since they are governed much more by sea temperatures than the energy available in the atmosphere.

Frankly I don't think that Pauluis and Dias (or the Science editors, referees, and commentator) properly thought through the effect of transfering kinetic and gravitational potential energies (via raindrops) from higher levels in the troposphere to lower levels through conversion into kinetic and heat energies.

Thank you Doc!

We seemed to have missed anything severeā€¦ a break in the line went over us.
