Freezing rain and snow have fallen at elevation across the Whites and Longfellows adding snow depth in Tuckerman Ravine. Additional snows are possible through Wednesday.
We are on the backside of the latest Spring storm that dropped 2-4" of rain across New England. Temperatures were definitely cold enough above 3000 feet to support snowfall, but a nose of warm air aloft led to a mix of freezing rain and snow across the summits of the Whites and Longfellows in western Maine. Snowfall totals above 3000 feet were generally in the 2-5" range with Mt. Washington reporting in with 3.9" of new snow on Sunday (23 April) and 3" of new snow on Monday (24 April).
Hermit Lake SNOTEL snow depth analysis during the last 48 hours (ending on Tuesday AM).
Down in the base of Tuckerman Ravine at Hermit Lake (3750') the SNOTEL site logged an increase in snow depth from ~70 cm to ~81 cm (+4.3") on Sunday night, a decrease with rain on Monday down to ~78 cm, then another increase to ~85 cm (+2.8") on Monday night. All-combined, that's a gross positive increase of 7" with a net gain of ~5-6". The "Monday" forecast from the OpenSnow blend had 6" at Tuckerman and I will chalk this up to a win. It also had 7" at Sugarloaf which did not verify. So that's an "L".
Current Conditions and Short-Term Forecast
Latest radar animation ending at 8AM on Tuesday 25 April.
We still have snow falling across the Whites and Longfellows on Tuesday morning with a combination of upslope southeasterly flow and a trough of cold air aloft. These snow showers, which should mix with freezing rain, should continue throughout the day in the mountains and lead to additional localized accumulations at elevation.
HRRR model total snowfall using model-derived ratio through 2AM Wednesday night.
Total snowfall through Wednesday night will be confined to the Adirondacks, northern Greens, Whites and Longfellows with accumulations generally less than 3" with potential maxima >6" in the ADK high peaks and Presidentials. According to the OpenSnow blend, Tuckerman is looking at the potential for an additional 2-3" each day through Thursday with 0-1" totals at Jay, Killington, Sugarbush, and Sugarloaf.
GFS model forecast for 2PM Saturday (29 April) and 2PM Sunday (30 April).
The weekend forecast is looking to feature some sunshine possible early on Saturday followed by increasing clouds with rain approaching from the west as we get into Sunday. Temperatures should generally be in the mid-50s across the valleys with upper 30s and low 40s on the slopes. Snow conditions will be soft as overnight lows have largely settled above freezing the last several days, especially below 3000 feet, with a decent amount of rain.
This post is likely the last New England Daily Snow Update. The next Update will feature a season recap and likely get posted on Thursday (27 April) or Friday (28 April).
