SUMMARY OF CLIMATOLOGICAL DATA 



MARCH 2014

...MUCH COLDER TEMPERATURES THAN NORMAL ...
...NEAR NORMAL RAINFALL ...


  • Some Weather and Climate News - from member Lowell Koontz (GAV)   Lowell Koontz sent along a few links for you to check-out: House passes Weather Forecasting Improvement Act of 2014? http://www.washingtonpost.com/blogs/capital-weather-gang/wp/2014/04/02/house-passes-weather-forecasting-improvement-act-of-2014/ ; 4 consecutive total lunar eclipses starting April 15, 2014: http://science.nasa.gov/science-news/science-at-nasa/2014/27mar_tetrad/


  • March 25th, 2014 Snowfall Totals - from NWS Wakefield (AKQ)   National Weather Service Office Wakefield has prepared a public information statement listing spotter reports for snowfall for the late March storm in Virginia and Maryland (within their CWA): http://www.weather.gov/media/akq/stormSUM/Snow_Event_Mar25_2014.pdf


  • Historical Database of Tornadoes - 1980-2012 - from Kevin Shaw of ACON DC/MD/DE   "I got this email from my friend Henry S down in TN (Retired NWS forecaster) ...pretty neat historical database of tornadoes! Check it out!" It includes a link to an interactive map showing all tornadoes which occurred across the U.S. from 1980 through 2012. http://storymaps.esri.com/stories/2014/tornadoes/#


  • 2014 AMERICAN WEATHER CONFERENCE - from Kevin Shaw, ACON DC/MD/DE   "Read all about 2014's conference at the link below. I have attended these in the past and they are always quite excellent. Hope some of you can make it!" Please visit: http://conference.americanwx.com/


  • "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


  • NWS AKQ MONTHLY RAINFALL ANALYSIS (Virginia)      Don't forget these new products for Virginia from NWS Wakefield compiled from ASOS...COOP...RAWS REPORTS | Monthly Rainfall Analysis - http://www.weather.gov/akq/MONTHLY_RAINFALL_ANALYSIS -


  • NOHRSC INTERACTIVE SNOW INFORMATION      Here's a fantastic resource for you snowbirds who wish to track and analyze snowfall across the States. Visit http://www.nohrsc.noaa.gov/interactive/html/map.html
