December 2020 Forecasts and Discussions

The s-word has started appearing in the weather forecast for my zone.

.FRIDAY NIGHT...Mostly cloudy with a slight chance of rain in the evening, then partly cloudy with a chance of rain, snow and a slight chance of light freezing rain after midnight. Lows in the lower to mid 30s.

Also this, in the forecast discussion:

.LONG TERM /SATURDAY THROUGH TUESDAY/...The take home message of the long term is that it is going to be wet. Saturday is going to be the day that we need to be vigilant of. Snow levels are dropping to around 1000 feet, temperatures are at or near freezing in many locations (particularly Whatcom County and South of Olympia). And we have rain on the way. With this there is the potential for a wintery mix of rain and snow in the lowland areas Friday night into Saturday morning. During this time we are also concerned for the possibility of freezing rain. Freezing rain would be most probable in the valleys of Whatcom and Skagit counties, including areas near the water. The other main area of concern for freezing rain is the low laying areas south of Olympia, as low temperatures are below freezing. We are still a few days out and confidence is low for the freezing rain, but due to the possible impacts, the need to include it in the forecast was there. Keep updated on the forecast in the coming days as confidence will grow on if/when/where freezing rain and the wintery mix of precipitation could occur.

Freezing rain more so towards the Canyon and areas just outside of it. Agassiz and Hope perhaps, but the cold air looks really shallow in the Valley. Warm advection drizzle could better our chances but any precip intensity that is greater will quickly warm the surface up.

FWIW, the extended (clownrange) GEFS from last night says maybe the #beginningofJAN.

Looks like climate change claimed a victim at Blackcomb. The Hortsman T Bar is no more. The glacier melted too much to keep it in operation.

Warm zonal and AR pattern turning into a strong +ENSO like pattern with a rex block and all cold air retreating to the poles. In fact...the EPS pretty much blowtorches the entire globe outside of Siberia in the last frame...

Onto 2021.

It keeps showing cold after day 25-30 and has been the past month.

2021 will deliver something. 2020 wouldn't dare give us a break from its douchery. In the meantime, looks like the slppes are calling next week

Not really, I remember many times during November where it kept showing warm in December.
