SUMMARY OF CLIMATOLOGICAL DATA 



JANUARY 2012

...A MILD WINTER CONTINUES...
...MONTHLY AVERAGE TEMPERATURES ARE WELL-ABOVE NORMAL...
...WITH ONLY A FEW EXCEPTIONS, RAINFALL & SNOWFALL REMAIN BELOW NORMAL...

  •   PRESTO    Kevin Shaw of ACON DC/MD/DE sends along this resource information. PRESTO sums up the weather for the month at the major reporting sites in the Washington DC and Baltimore areas, with supplemental reports from smaller stations on individual events. The new link for these reports is http://www.nws.noaa.gov/os/presto/


  •   NCDC DATA IS NOW FREE    The National Climatic Data Center in Asheville now provides weather data at no cost. The free data can be found at http://www7.ncdc.noaa.gov/IPS/


  •   NATIONAL WEATHERPERSONS DAY    From Kris Allred of WSAV-TV comes this tribute to us all! Some are celebrating more than just the Super Bowl on February 5th! February 5th is also the day to celebrate the men and women in weather! The date is set for National Weatherpersons Day! It's a day to celebrate and recognize weather-reporting excellence. The date was chosen to commemorate the birth of John Jeffries... who was born on Feb. 5, 1744. Jeffries was one of America's first weather observers. He began taking daily weather observations in the city of Boston in 1774, and he took the first balloon weather observation in 1784. This celebration isn't just for those who work in the field of meteorology. It's for anyone who is dedicated to the science. This can include meteorologists at local National Weather Service offices to storm spotters, amateur meteorologists and just weather watchers.





  •   WOOMERGAMA, NEW SOUTH WALES AUSTRALIA    It's summertime in Australia and this pic (on the right) was taken recently by Jane O'Neill in New South Wales Australia. Jane O'Neill of the Trentham Stormchasers posted this picture on FACEBOOK. Jane adds that the hail measured 2-4 cm, produced a loud humming noise for 20 minutes as the swathe approached, was part of a very slow moving cell that retrograded, and that visibility was zero for a few minutes.





  •   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 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!!


  • DROUGHT MONITOR    http://drought.unl.edu/MonitoringTools/USDroughtMonitor.aspx    More information on drought can be found at NOAA's Drought Information Center http://www.drought.noaa.gov/


  • REMINDER   All National Weather Service station data listed herein is preliminary and may be subject to change.  The data has not been certified and cannot be used in legal actions.  Only reports certified by the National Climatic Data Center in Asheville, NC can be used for these purposes.

There were 19 days the temperature was 50F or above. January had only 18 days the minimum temperature was 32F or lower and the maximum temperature rose above freezing all 31 days of the month; both are new records for January. The 1.95 inches of precipitation for January was a -0.82 inch departure when compared to the past three-year average. The month had 10 days with precipitation. The maximum temperature for January was 71F on January 27th. January also had a temperature range of 22.7F, which was caused in part by the clear month. This January was the clearest January on record at Glen Allen (Records since August 2008). The average temperature range at the Richmond International Airport was 21.6F the highest since 1990 when it was 21.9F. Glen Allen's lowest minimum temperature was 15F which was recorded on the 4th which was the coldest reading since January 23, 2011 when it was 13F. The lowest barometric pressure of the month was 29.38 inches and recorded on the 13th and the highest was only 30.61 inches on January 16th. The maximum wind gust for the month was 41 mph SSE that occurred on the 17th of the month at 1208 and made for the windiest day (wind run was 247.0 miles) since August 27th and hurricane Irene when a 284.1 mile wind run occurred. This is also the windiest January on record at the Glen Allen Station. (Records since August 2008). The Richmond International Airport set only one daily record for the month. On January 6th the 37F temperature range set a new record for the date. The previous record was 35F set in 1929. The January mean temperature of 42.7F was the 20th warmest in the past 132 years.

On the precipitation side, the month was 0.99" below normal with 2.04" measured. We had scattered light to moderate periods of precipitation throughout the month. We had three periods of light snow with 0.8" falling on the 9th and 0.5" falling on the 20th and 21st. For the season, we have now had 2.3" of snow; well below our normal. " - [ + - ]
