Multi-model 2 week outlook: fine weekend (spotty mixed precip). 5-10cm snow south Monday. Passing rain showers south/snow north later in week. Mild.
Could be a snow event late next weekend while turning colder... so ground should be white ahead of Christmas.

Blizzard-like in parts of eastern NS & E PEI.
Winds subsiding in the west; snow & winds ease off by tonight in the east.
Just a passing thin band of mixed precip Sat night-Sunday. Similar weak systems next week. Snow next weekend??

Just spotty showers/wet flurries this am become more widespread this aftn. A couple of snow bands on a cold front in NB crosses NS-PEI this evening: turns windy & COLD; wet or slushy surfaces will FREEZE. The very cold NW winds will trigger onshore snow with blizzard-like conditions in CB Highlands.

Dean is in Hammonds Plains. I expect his 5cm was also consistent with what fell in Fall River and YHZ airport.
10am update in HP: Another 2cm snow (4.3mm water content), mixed with about 0.6mm of rain. Storm totals now at - 4.8cm snow (10.6mm water), and 32.9mm rain. Total precip=43.5mm water. Currently very light flurries, windy, temp near 2C. @yhzweatherguy.bsky.social #NSStorm

The CoCoRaHS reports illustrate the challenge measuring & predicting snow in the Maritime climate.
The Rawdon observer measured 33.5mm of total precipitation (melted snow plus rain). The snow depth was 8.1cm, which contained 17.5mm of water (very wet heavy snow).
A very complete observation. thanks!

Interesting article... the weather forecast world is changing rapidly: www.npr.org/2025/11/29/n...
As the 2025 Atlantic hurricane season ends, the future of forecasting is AI
Meteorologists are surprised that the weather model that did the best job forecasting hurricanes this year was a new one, introduced by Google. AI may be the beginning of a new era of forecasting.

There are some consistencies in snowfall forecasts for late Tuesday thru Wednesday:
- the Atlantic coast most likely to have a rain mix; so lower snowfalls
- high ground over the South Mountain (Ann Valley) & N NS most likely to have higher snowfalls.
- wet snow not as deep, but is heavy!
Still TBD

Had 22.6mm of rain. Just fog & drizzle over the S&W half of the Maritimes which clears to a sun-cloud mix. The rain moves off the N&E with clearing not til later in day.
The multimodel outlook has cooling over next few days. A warm up with rain Sunday night; then turning colder & wintry next week?
