  • THE NOAA RESOURCES PAGE (from CoCoRaHS)       The National Oceanic and Atmospheric Administration (NOAA) has many exciting informative resources available for the public to view and learn about our oceans and atmosphere. CoCoRaHS in partnership with NOAA will continue to strive to bring you the latest products and information as they become available. During the year NOAA runs a series of weather awareness and preparedness weeks providing important information on a variety of weather related subjects. These include: Severe Weather Preparedness Week, Flood Awareness Week and Lightning Safety Awareness Week just to name a few. Visit the NOAA Resources page to see this year's schedule. To learn more about NOAA Resources listed on the CoCoRaHS Web site click on the NOAA logo on the left side of our home page: www.cocorahs.org or click here: NOAA Resources http://www.cocorahs.org/Content.aspx?page=noaa


  • WHAT "TYPE" OF PRECIPATION IS FALLING BY YOU? (from CoCoRaHS)       NOAA's NSSL appreciates your help! NOAA's National Severe Storms Laboratory (NSSL) is located in Norman, Oklahoma. They study severe and hazardous weather processes and develop tools to help National Weather Service forecasters, and federal, university and private sector partners use weather information more effectively. NSSL has launched its iPhone and Android apps to collect precipitation reports from the public. The NOAA National Severe Storms Laboratory, in partnership with the University of Oklahoma has launched an app where users can anonymously report precipitation from their iPhone or Android through the "mobile precipitation identification near the ground "mPING" app. NSSL researchers will compare the reports with what radars detect and use the information to develop new radar and forecasting technologies and techniques to determine whether snow, rain, ice pellets, mixtures or hail is falling. NSSL hopes to build a valuable database of tens of thousands of observations from across the U.S. The apps are available on iTunes or Google Play for use on both phones and tablets. The reports can be viewed here in real-time: http://www.nssl.noaa.gov/projects/ping/display/

    The lab's main PING page: http://www.nssl.noaa.gov/projects/ping/

    If you have some extra time please give this a try, NSSL would really appreciate your help!



  • THE NATIONAL PHENOLOGY NETWORK  (from CoCoRaHS) Join the USA National Phenology Network! Document how plants and animals respond to local weather conditions using Nature's Notebook. The Network is offering CoCoRaHS participants a chance to enhance their observations by also reporting on what plants or animals are doing! Plants and animals respond strongly to environmental conditions. Trees are cued by warming spring temperatures to begin leafing out. A combination of temperature and soil moisture conditions influence when they flower and produce fruits and seeds. Similarly, birds and insects migrate and complete their life cycles based on temperature and sun angle cues. The timing of these seasonal life cycle events is termed phenology. Because plants and animal life cycle events are so closely tied to weather conditions, they are being affected by climate change. In many parts of the country, trees and plants are leafing out and flowering earlier than in previous decades. Though the longer growing season can be beneficial in some respects, there are risks and drawbacks as well. For example, early leaf-out comes with a higher risk of plant damage due to late frosts. Spring 2012 was a good example of the widespread damage that can occur from a very early spring - fruit and vegetable crops were decimated in much of the Midwest. NPN welcomes you to help them better document how plants and animals are responding to local weather conditions. Your observations of plant or animal phenology collected via Nature's Notebook are made available publicly and are regularly used by researchers and decision makers. Phenology observations made at the same locations that weather observations are collected are especially valuable! Learn more! NPN invites you to join one of their spring campaigns at http://www.usanpn.org/Spring2013Campaigns. They are especially interested in collecting observations for these species. However, you are welcome to collect and submit observations on any of the 900 species of plants and animals for which protocols are available at http://www.usanpn.org/participate/observe. Questions?

    Arlington - " MARCH TYPICALLY SIGNIFIES A TRANSITION FROM WINTER COLD TO SPRING WARMTH FOR WASHINGTON DC...BUT WINTER OVEREXTENDED ITSELF THIS YEAR. TEMPERATURES THIS MARCH WERE COLDER THAN NORMAL. THE MONTHLY AVERAGE TEMPERATURE OF 43.6F DEGREES MADE IT THE COLDEST MARCH SINCE 2005. THE MONTHLY MAXIMUM TEMPERATURE OF 51.5F WAS THE SECOND COLDEST FOR MARCH IN THE PAST 20 YEARS /MARCH 2005 WAS ONLY 0.3F DEGREES COOLER THAN THIS MARCH/ AND THE 10TH COLDEST FOR MARCH SINCE OFFICIAL WASHINGTON DC OBSERVATIONS WERE MOVED TO REAGAN NATIONAL AIRPORT IN 1945. MARCH 2013 WAS THE FIRST MARCH SINCE 1958...AND THE SEVENTH MARCH SINCE WASHINGTON DC TEMPERATURE RECORDS BEGAN IN 1872...WITH NO 65-DEGREE OR HIGHER DAYS THE ENTIRE MONTH. COMPARE THAT TO LAST MARCH...WHEN THE MOST 65-DEGREE OR HIGHER DAYS /18/ IN MARCH WERE RECORDED. WASHINGTON DC ALSO EXPERIENCED THEIR WARMEST MARCH ON RECORD LAST YEAR. THE MAXIMUM TEMPERATURE OF 39F DEGREES ON THE 25TH WAS THE LATEST OCCURRENCE IN SPRING WITH A SUB-40F DEGREE DAY AT DCA SINCE 1971 /MAXIMUM TEMPERATURE OF 38F DEGREES OCCURRED ON 26 MARCH 1971/. PRECIPITATION FOR THE MONTH WAS SLIGHTLY BELOW NORMAL. NEARLY ONE-THIRD OF THE MONTHLY PRECIPITATION FELL IN ASSOCIATION WITH A STRONG COASTAL STORM THAT IMPACTED THE AREA ON THE 6TH. THE 1.6 INCHES OF SNOW RECORDED THIS MARCH WAS MORE THAN THE 2012-13 SEASONAL SNOWFALL TOTAL PRIOR TO MARCH 1 /1.5 INCHES WAS MEASURED PRIOR TO MARCH/. REAGAN NATIONAL AIRPORT MEASURED 1.4 INCHES OF SNOW ON THE 25TH... WHICH SNAPPED A 788-DAY STREAK WITHOUT AN INCH OF SNOW RECORDED ON A CALENDAR DAY THAT DATED BACK TO 27 JANUARY 2011. THE PREVIOUS LONGEST STRETCH ON RECORD WITHOUT A DAY OF ONE INCH OR MORE OF SNOW WAS 700 DAYS FROM 5 FEBRUARY 1975 THROUGH 4 JANUARY 1977. " - [ - - ] - Notes from NWS Sterling, VA

    Bridgewater - Clayton adds: " I don't ever remember having three snowstorms in March. We had more snow in March . We have had more snow in this month during the first week when we were pelted with 24 inches in storms. This is the most March snow in the last 20 years. First March snow in the last 20 years. Probably, we won't get any more snow this spring, but we have had three snows in April during the past 50 years. " - [ - + ]

    Chantilly - Russ sends these additional notes: " Coldest March in two decades with above average snowfall and overall precipitation slightly below the norm. The mean monthly temperature was 41.5 (-2.7). The mean high temperature was 50.6 (-4.9) and the mean low temperature was 32.5 (-0.4). March precipitation was 3.11" (-0.27"). When snow lovers had all but given up on snow, we had the threat of a major winter storm. Winter Storm Warnings went up across the region, schools and the Federal government closed, but at this site, though the most we received all winter, it was still only 3.0". We had snow on the 5th (0.1"), 6th (new record 2.6"), 18th (0.9"), 24th (T), and 25th (new record 3.0"). Monthly snowfall totaled 6.6" (+3.8"). This winter, we received 9.5" of snow. Maybe next year, snow lovers. *Please note, anemometer is currently partially obstructed from the North and East " - [ - - ]

    Dulles - from NWS Sterling (KLWX): " MARCH TYPICALLY SIGNIFIES A TRANSITION FROM WINTER COLD TO SPRING WARMTH FOR DULLES...BUT WINTER OVEREXTENDED ITSELF THIS YEAR. TEMPERATURES THIS MARCH WERE COLDER THAN NORMAL. THE MONTHLY AVERAGE TEMPERATURE OF 40.2F DEGREES MADE IT THE COLDEST MARCH SINCE 1996 AND THE 8TH COLDEST MARCH SINCE RECORDS BEGAN IN 1962. THE COLDEST MARCH ON RECORD WAS 1984 WHEN THE MONTHLY AVERAGE TEMPERATURE WAS 37.5F DEGREES. THE MONTHLY MAXIMUM TEMPERATURE OF 49.2F WAS THE COLDEST FOR MARCH SINCE 1993 AND THE 5TH COLDEST FOR MARCH ON RECORD. THE COLDEST MARCH ON RECORD WAS 1984 WHEN THE MONTHLY MAXIMUM TEMPERATURE WAS 47.6F DEGREES. MARCH 2013 WAS ONLY THE SECOND YEAR ON RECORD WITH NO 65-DEGREE OR HIGHER DAYS IN MARCH /2001 WAS THE OTHER/. COMPARE THAT TO JUST LAST YEAR...WHEN THE MOST 65-DEGREE OR HIGHER DAYS /20/ IN MARCH WERE RECORDED. DULLES ALSO EXPERIENCED THEIR WARMEST MARCH ON RECORD LAST YEAR. THE MAXIMUM TEMPERATURE OF 39F DEGREES ON THE 25TH WAS THE LATEST OCCURRENCE IN SPRING WITH A SUB-40F DEGREE DAY AT DULLES SINCE 2001 /A MAXIMUM TEMPERATURE OF 38F DEGREES OCCURRED ON 26 MARCH 2001/. PRECIPITATION FOR THE MONTH WAS NEAR NORMAL. JUST OVER ONE-THIRD OF THE MONTHLY PRECIPITATION FELL ON THE 12TH WHEN A STRONG COASTAL STORM IMPACTED THE AREA. THE 7.4 INCHES OF SNOW RECORDED THIS MARCH WAS WELL ABOVE THE 1981-2010 MONTHLY NORMAL. IT WAS ALSO THE SNOWIEST MARCH SINCE 1999...THE 9TH SNOWIEST MARCH ON RECORD...AND THE SNOWIEST MONTH SINCE JANUARY 2011. TWO DAILY MAXIMUM SNOWFALL RECORDS WERE SET THIS MONTH. ON THE 6TH...3.3 INCHES OF SNOW BROKE THE PREVIOUS DAILY SNOWFALL RECORD OF 0.2 INCHES IN 1989. ON THE 25TH...3.2 INCHES OF SNOW BROKE THE PREVIOUS DAILY SNOWFALL RECORD OF 1.2 INCHES IN 1990. 2013 WAS ONLY THE THIRD YEAR ON RECORD WITH MULTIPLE DAYS IN MARCH OF THREE INCHES OR MORE OF SNOWFALL /1984 AND 1999 ALSO RECORDED TWO SUCH DAYS IN MARCH/.

We had lightning seven times during the morning snow and sleet storm of March 6th. The maximum wind gust during March was 35 mph and that occurred on the 6th at 1714 hours from the NNE. A bolide meteor was seen at about 1954 in NE sky-it started out white about 3/4 size of the moon with a white tail almost looking like a comet and quickly faded to a deep green and dimmed rapidly as it faded below the horizon-all this took place in about 3 seconds. " - [ - + ]

    Herndon - Randy reports: " March was well-below normal for temperature and slightly above for precipitation. The temperatures ranged between a high of 63 and a low of 24 (note that 63 was the lowest high temperature for my site of over 20 years). The average high temperature of 49.4 degrees was also the lowest I have ever recorded. We averaged 4.8 degrees below normal for the month. On the precipitation side, the month was 0.11 above normal with 3.79 measured. We had several days of very wet snow and some sleet during the month, and received a total of 8.2 for a total of 12.1 for the year. I measured 4.2 on the 6th and 3.5 on the 25th. " - [ - + ]
