12/16/2014 1/07/2015 9:00 AM 23 11.00 M M At least 11". Rain gauge was full upon our return to station after being away for three weeks.
1/8/2015 1/21/2015 9:00 AM 14 3.37 M M Station's daily reporting has been down due to two things: vacation, and then awaiting replacement of broken inner gauge tube. This reading is accurate. Previous reading (11") is more accurately 'greater than or equal to 11"'. But judging from nearby stations, 11" is probably quite close to actual amount.
