  • WORLD AND U.S. ANTI-CYCLONIC (HIGH BAROMETRIC) PRESSURE RECORDS - from Kevin Shaw, ACON Contributor      "I found the following info from Chris Burt's article on the highest barometric pressure readings in the world. The link to the article appears below. The accepted World Record for highest barometric pressure ever recorded occurred in Siberia on December 31st, 1968 at 32.01" (1083.3 MB). Fascinating discussion on it and also on some higher value recorded since in Mongolia, which have not been accepted due to elevation - see article for very interesting explanation, plus a wealth of other goodies on the subject. Read the article here: http://www.wunderground.com/blog/weatherhistorian/world-and-us-anticyclonic-high-barometric-pressure-records    I believe if you look around Chris's area there on Weather Underground, you will find a companion article on the lowest barometric pressure records also."


  • "TEN-TO-ONE?" THE ODDS ARE "PERHAPS SOMETIMES!" - from CoCoRaHS      Does ten inches of fresh snow melt down to one inch of water content? Usually not, but sometimes. It is remarkable that the 10:1 snow-to-water-content "myth" has survived this long. Cleveland Abby, a renowned 19th Century scientist and meteorological observer wrote in the 1888 Treatise on Meteorological Apparatus and Methods, "The measurement of the height of water by assuming ten inches of snow to one inch of water is subject to a large range of error because of the wide variability of this ratio for different kinds of snow." Almost 125 years later, the topic is still debated. All we need to do is look at the many shapes and sizes of snowflakes to realize that the water content of snow will vary. CoCoRaHS data quickly show the large variations that are possible. Very dry and fluffy snow falling with light winds and cold temperatures may have 0.30" or less water in ten inches of new snow. On the other side, very wet snow may have more water -- two inches of water from ten inches of snow is not that unusual. For sleet (ice pellets) the water content can be even more. That is why it is so important to independently measure both the accumulation of new snow, the water content of that snow, and the total depth of new and old snow on the ground. Furthermore, it doesn't take long to tell when you're out walking, playing or shoveling snow. You can feel the mass and the resistance from a dense, wet snow. Like it or hate it, snow is amazing stuff. For more information about the curious and dynamic properties of snow click here: http://ccc.atmos.colostate.edu/pdfs/snowbook.pdf


  • MEASURING FREEZING RAIN + SNOW TRAINING SHORTS - from CoCoRaHS      Freezing rain will most likely make an appearance in some parts of the country this month. How does one measure it? Good question. For a quick primer please click here: FREEZING RAIN at http://www.youtube.com/watch?v=rLwlaP_CFl8&list=PLS0EU9SKRY0_liw4Z60q_zodgCz-etYB5&index=8    The title of this message mentions snow training shorts. What are those? We're not talking about weather apparel here; these are short animations showing how to measure precipitation in wintry weather. Please take a look: CoCoRaHS SNOW SHORTS at http://www.youtube.com/playlist?list=PLS0EU9SKRY0_liw4Z60q_zodgCz-etYB5 Additional training on both subjects can be found on our CoCoRaHS Training Slide Show Page: http://cocorahs.org/Content.aspx?page=training_slideshows

    Arlington/Washington, D.C. - " NOVEMBER IN WASHINGTON DC WAS COLDER THAN NORMAL. THE AVERAGE MONTHLY TEMPERATURE OF 46.6F WAS TIED WITH 2000..2008 AND 2012 FOR THE COOLEST NOVEMBER IN THE PAST 15 YEARS. THE LAST WEEK IN NOVEMBER WAS ESPECIALLY COLD WHEN MULTIPLE SHOTS OF ARCTIC AIR REACHED WASHINGTON DC. THE AVERAGE TEMPERATURE OF 34.8F FOR THE 24TH-30TH WAS THE 10TH COLDEST LAST WEEK IN NOVEMBER ON RECORD IN WASHINGTON DC...AND THE COLDEST SINCE 1956 (WITH AN AVERAGE TEMPERATURE OF 33.2F). THE MAXIMUM TEMPERATURE OF 34F ON THE 24TH WAS THE LOWEST DAILY MAXIMUM TEMPERATURE IN NOVEMBER AT DCA SINCE 21 NOVEMBER 1987 (33F). NOVEMBER IN WASHINGTON DC WAS DRIER THAN NORMAL. ONLY SEVEN DAYS RECORDED MEASURABLE RAINFALL. THE ONE HEAVY RAIN EVENT ON THE 26TH- 27TH TOTALED 2.20 INCHES...WHICH ACCOUNTED FOR 75 PERCENT OF THE MONTHLY RAINFALL. " - [ - - ] - from NWS Sterling, VA

    Chantilly - from Russ Topping: " November temperatures and precipitation averaged below normal. The mean monthly temperature was 43.9 (-2.5). The mean high temperature was 53.6 (-3.9) and the mean low temperature was 34.3 (-1.0). A record low high temp was set on the 24th (34), as arctic air moved in, temps nose-dived, and we had one of the coldest ends to November on record. November was drier than average. Rainfall totaled 2.98" (-0.43"), primarily falling on the 26th (1.68") and 27th (0.52") and accounting for two thirds of my precipitation. No frozen precip was observed. Of note was the drastic swing in barometric pressure which was measured between the 27th (29.537") and 29th (30.727"). The pressure measured on the 29th may be the highest I have recorded at this station (further research required!). *Please note, anemometer is currently partially obstructed from the North and East " - [ - - ]

    Dulles - from NWS Sterling (KLWX): " NOVEMBER AT DULLES WAS COLDER THAN NORMAL. WITH AN AVERAGE MONTHLY TEMPERATURE OF 42.9F...2013 HAD THE 11TH COLDEST NOVEMBER ON RECORD. THE LAST WEEK IN NOVEMBER WAS ESPECIALLY COLD WITH MULTIPLE SHOTS OF ARCTIC AIR. THE AVERAGE TEMPERATURE OF 30.7F FOR THE 24TH-30TH WAS THE COLDEST NOVEMBER WEEK ON RECORD AT DULLES. THE PREVIOUS RECORD COLDEST NOVEMBER WEEK AT DULLES WAS 31.1F ON THE 19TH-25TH NOVEMBER 2000. THE MAXIMUM TEMPERATURE OF 32F ON THE 24TH BROKE THE PREVIOUS DAILY LOW MAXIMUM TEMPERATURE RECORD OF 36F SET BACK IN 1971. IT WAS ALSO THE DAILY MAXIMUM TEMPERATURE IN NOVEMBER SINCE 28 NOVEMBER 1996...WHEN IT WAS 31F. THE MINIMUM TEMPERATURE OF 16 DEGREES ON THE 25TH WAS TIED FOR THE 13TH COLDEST MINIMUM TEMPERATURE IN NOVEMBER ON RECORD. NOVEMBER WAS DRIER THAN NORMAL. THE ONE HEAVY RAIN EVENT ON THE 26TH-27TH TOTALED 2.22 INCHES...WHICH ACCOUNTED FOR 80 PERCENT OF THE MONTHLY RAINFALL. THE 1.72 INCHES OF RAINFALL ON THE 26TH SET A DAILY RECORD RAINFALL FOR DULLES. THE PREVIOUS RECORD WAS 1.02 INCHES IN 1996. " - [ - - ]

    Glen Allen - from Lowell Koontz: " This November was the second coldest on record (records since 2008) as the monthly mean temperature was 46.4 F, a -3.1 F mean temperature departure when compared with Glen Allens five year average. Precipitation for Nov. was 3.68 inches, which was a departure of only -0.46 inches. It was a dry month until the 2.80 inches of precipitation that occurred on the 26th and 27th. The maximum temperature for November was 73 F on the 2nd. The lowest minimum was 17 F recorded on the 25th. There were 12 days the minimum temperature was less than or equal to 32 F. The highest barometric pressure ever recorded in November was 30.69 inches on the 29th and 30th which was also the highest since March 6, 2012 when it was 30.71 inches. The average daily pressure for the month was the highest on record with 30.21 inches; the previous record was 30.18 inches in Nov. 2012. The predominance of high-pressure was associated with the unusually dry month until the low pressure of the 26th and 27th. The lowest dew point for the month was 0.7 F on the 24th, which was more than 7 F below the previous record low dew point. Glen Allen recorded both the highest daily mean temperature on record for November on the first and the lowest daily mean on record for November on the 25th. " - [ - - ]

    Herndon - from Randy Ashby: " November was below normal for temperature and slightly above normal for precipitation. The temperatures ranged between a high of 75 and a low of 17. The 17 degrees recorded on the 25th was the lowest low temperature that I have ever measured in November in the last 20+ years. On the precipitation side, the month was 0.17 above normal. It rained on 8 days during the month, but most of the rain came on the 26-27th when we received 2.41. We are now about 0.75 above normal for the year. " - [ - + ]
