SUMMARY OF CLIMATOLOGICAL DATA 



FEBRUARY 2014

...TEMPERATURES AVERAGE AT OR BELOW NORMAL...
...ABOVE NORMAL PRECIPITATION FOR MOST STATIONS...
Continued cold temperatures, especially in Virginia, with above normal precipitation at most stations for February 2014. However, temperature averages and precipitation totals were closer to normal than those of January. Severe weather was observed on the 21st across the region. (link to reports below).

  • 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

    Whiteville - from contributor Christopher Crawley: " Two weeks to the day from the snow/ice event in January… and we experienced Icemageddon 2014. It was noted by NWS-ILM to be a “historic” ice storm for the area. The event started Tuesday 2/11 with a period of sleet, which turned to snow, and then went back to sleet before ending late that evening. Shortly after midnight (into Wednesday 2/12), sleet began to fall once again in earnest, which changed to a steady freezing rain by daybreak. Freezing rain occurred, heavy at times throughout the day, with a measured ice accumulation between 0.67” and 0.75”. Precip changed to rain late Wednesday evening as temperatures rose above freezing. A period of slight sleet occurred on the backside of the low Thursday morning, 2/13. Schools again were closed Tuesday 2/11 through Friday 2/14. As much as 98% of Duke Energy customers in Columbus County (my county) were without power, and there was EXTENSIVE tree damage done. The 0.75” measurement for 24-hour precipitation is an ESTIMATED TOTAL as with the different precipitation types it was very difficult to ascertain. " - [ + - ]
