  • NEW MONTHLY NWS WAKEFIELD (KAKQ) PRODUCT       "The CoCoRaHS Team here at NWS Wakefield have created a new feature for our wonderful volunteers. This new feature is a monthly rainfall (sometimes snow!) summary that will show you in text and map form how your daily observations make a difference. The month of April had a very good and complete data set that combined well with other automated observations across the region. Thank you to ALL of YOU that made this possible!!! Here is the April CoCoRaHS climate summary in Adobe .pdf format to view at your leisure. Click here: http://genserva.com/acon/NWSAKQ_April2013_CoCoRaHS_Summary.pdf

    Thanks again for all that you do! Your data and efforts really do matter.
