NEW WEB SERVER FOR ACON VA/NC/SC
Our old web server has ended the providing of personal webspace
which we have used for years. Thus, our files have been migrated to a new commercial server.
Our new web address for the group is http://www.genserva.com/acon
For members of our group, this means we will be have unlimited space for file storage and we
can upload more of your photos to share. Of course, any photos you submit should
be weather-related and more significant than just a "pretty picture". However, in the
weather field there are just some "pretty pictures" worthy of notice, so submit an occasional
"pretty picture" and it may just get posted!!

CoCoRaHS On You Tube
from the CoCoRaHS website -"CoCoRaHS has launched the CoCoRaHS YouTube Channel (http://www.youtube.com/cocorahs).
This is the location where you will find official CoCoRaHS videos. Additional
videos will be added on a fairly regular basis. For those of you not familiar with
YouTube, the site is free and easy to access with your computer. With this
announcement, we have released a "new animated introduction video" describing the
network in an animated, easy to watch style. Our goal is to have something that
appeals to all ages, is attention grabbing, funny and still educational. We hope
you like it. Let us know what you think. If this video becomes popular we will
work with our artist to create additional training materials and other items of
interest. We hope that you'll take a moment to watch this new intro video and
share it with others. Thanks as always for your daily reports and keeping an eye
on the sky!"

Glen Allen - Lowell sends these notes: " There were two main events in October both of which had little effect on the West Henrico Co. - Glen Allen area. The thunderstorms on October 13th produced three tornadoes in Quantico in Prince William County, in Boswell Tavern in Louisa County, and the Woodhaven Shores area in New Kent County, VA. The storm gave this station only 0.46 inches of rain and one very close lightning strike. On the 29th a strong storm system moving up the East Coast (affecting ten states) dumped more than two feet of snow in NH and left more than 3 million homes and businesses without power and caused at least twenty deaths. We only had a trace of sleet mixed with rain around 1600 on the 29th. October was cooler and drier than average at the Glen Allen Station when compared to the Ashland Station. The monthly mean temperature was 58.6°F, a -0.8°F departure when compared to the Ashland, VA average. The 3.32 inches of precipitation for October at Glen Allen was a -0.15 inch departure when compared to the Ashland, VA average. The maximum temperature for October was 81°F and the lowest minimum temperature was 29°F recorded on October 30. The cold was really felt as it was near 80°F on the 25th. There were two frosts in October and both were heavy and killing on the 30th and 31st. The Richmond database recorded three records this month. The low maximum temperature of 45°F recorded on the 29th as a record low maximum for the date; previous record was 46°F in 1925. On October 12th the minimum temperature tied the previous record of 65°F set in 1983. The maximum on the 12th was 68°F giving a daily temperature range of 3° the lowest range ever recorded on that date. The previous record was 8°F set in 1985 and 1942. It was the 58th warmest and the 59th wettest October in the Richmond records. The highest dew point temperature for October was 72°F on the 13th at 1430 that made it feel like a summer's day. The lowest dew point was 26.1°F on the 30th at 1536. The maximum wind gust was 34 mph from the SSW that occurred on the 20th at 1057 preceding a cold front. "

The temperatures ranged between a high of 81 and a low of 31; with the first freeze occurring on the 30th. On the precipitation side, the month was 4.65" above normal with 8.48" measured. More than one half of this came during the 12th thru 14th when a series of very heavy, severe storms moved through the area. On the evening of the 13th, a "train" of extremely strong storms moved from the south to the north through western Fairfax County. Rainfall rates exceeded 5"/hr and peaked at 10.87"/hr at one time. The rain was so intense that the storm drain next to my house could not handle the flow and overflowed into my and my neighbor's backyard, flooding their basement (See attached photos with clicks here: Pic 1 and Pic 2. We received 3.76" of rain in a little over 2 hours. We also had the first snow of the year and the first that I have ever measured in October since starting measurements in measurements in 1992. It started as sleet and ended as snow and received about 0.5". For the year, we are now over 8.5" above normal for precipitation. " - [ - + ]
