That's the most I could find for NH on cocorahs. Saw 19.2" in Marlboro, VT - Windham County, 1482' elev. Looks like an outlier; 2nd might've been Landgrove with 12" (can't recall the county.)
Measured 1.4" total, 0.7" at 9 last night and a repeat at 7 this AM as the snow was tapering off. Storm total was 1.08" with 0.28" from accumulating snow and 0.80" from RA and melt-on-contact snow, which was mainly 10:30 A to 2 P yesterday. Must've switched to RA during the night as the morning 0.7" had 0.10" LE and the bucket held 0.36". Got into Farmington by 7:45 this morning and saw less there than at my place, while Temple at 1220' reported 8.3", tops for Maine cocorahs.
