January 9, 2022 Ice Storm

On January 8, 2022, a winter weather advisory was issued for my local area. Significant ice accumulation was predicted.

…WINTER WEATHER ADVISORY IN EFFECT FROM 2 AM TO2 PM EST SUNDAY…

  • WHAT…A brief period of mixed precipitation, changing to
    freezing rain. Total snow and sleet accumulation of less than
    one inch and ice accumulations of up to one tenth of an inch.
  • WHERE…Portions of central Pennsylvania.
  • WHEN…From 2 AM to 2 PM EST Sunday.

I obtained a 3/4″ dowel, and cut it to the prescribed 20″ length. Before installing the dowel outside, I measured the diameter with digital calibers (0.74″). That was the baseline measurement.

I then secured the dowel to the railing of my deck with 1/2″ clamps.

The ice storm developed in the early morning hours of January 9, 2022. An ice storm warning was issued.

…ICE STORM WARNING IN EFFECT UNTIL 2 PM EST THIS AFTERNOON…

* WHAT…SIGNIFICANT ICING. ICE ACCUMULATIONS OF ONE QUARTER TO ONE-HALF INCH.
* WHERE…NORTHERN CLINTON, NORTHERN CENTRE, SOUTHERN CENTRE, MIFFLIN AND SOUTHERN CLINTON COUNTIES.
* WHEN…UNTIL 2 PM EST THIS AFTERNOON.
* IMPACTS…EXTREMELY DANGEROUS TRAVEL CONDITIONS. UNTREATED SURFACES WILL BE VERY SLIPPERY. ISOLATED POWER OUTAGES ARE POSSIBLE.

At 8 AM EST, ice had already accumulated on objects.

I did my first measurement:

By the following calculation, (0.95 – 0.74) / 2, the ice accumulation was measured at 0.11″.

At 10:20 AM EST the ice had accumulated to 0.14 inches.

The ice storm ended soon afterward, and that was the extent of the ice accumulation.

    Wow! This looks like an Earth Science class lab that would have made me hope that I’d have a good lab partner.

    We had icy conditions this morning, but the temperature rose by mid-morning, leaving wet roads and driveways – and a bit of slush.

    Best, Marcia
