AS OF 650 PM EST FRIDAY...HAVE UPDATED THE FORECAST TO UPGRADE
ADVISORY TO A WINTER STORM WARNING. A NARROW BAND OF MODERATE TO
HEAVY SNOW DEVELOPED ACROSS NORTHERN NEW YORK AND
EARLIER THIS EVENING ALONG AN AREA OF DEFORMATION ALOFT. SNOWFALL
TOTALS IN THE
WINDS ARE FUNNELED DOWN AND CONVERGE ALONG THE NARROWING CHAMPLAIN
VALLEY. THIS HAS RESULTED IN SNOWFALL AMOUNTS OF 3 TO 6 INCHES IN
JUST A COUPLE OF HOURS. SEE ALBPNSBTV FOR A FULL LISTING OF
SNOWFALL AMOUNTS SO FAR. BUFKIT SOUNDINGS ARE SATURATED TO NEARLY
25 KFT AND INDICATE FAVORABLE SNOW GROWTH EXISTS FROM THE SURFACE
UP TO 10-15 KFT. GIVEN THESE FACTORS...FEEL HEAVY SNOWFALL WILL
CONTINUE THROUGH THE NEXT FEW HOURS AND UPPED STORM TOTAL SNOWFALL
AMOUNTS TO AROUND 8 INCHES IN
HIGHER AMOUNTS POSSIBLE. NO OTHER CHANGES ARE NEEDED AT THIS TIME.
ALL UPDATED PRODUCTS HAVE BEEN ISSUED.
When I saw that extra area of deformation snow on the radar, it seemed likely that
Back at the house I found 7.9 inches of new snow on the snowboard, and the snow had stacked up fairly vertically as opposed to creating a trapezoidal shape the way many snowfalls do. So as of now we are right near the top end of the 4 to 8-inch accumulations forecast in our winter storm warning, and we may pick up a bit more snow overnight. I measured 0.40 inches of liquid from my core sample off the snowboard, and as there was a lull in the snowfall not long after my observations, I also brought in the snow/rain gauge. It really looked like the gauge had overflowed, but the liquid it collected (0.36 inches) was only 10% below what I got off the snowboard, so it apparently didn’t miss too much of the precipitation. The new snow is beautiful powder with a water content of ~5%, so it should ski beautifully assuming it wasn’t too hammered by wind in the higher elevations.
