2018 Spring Discussion Thread (Northern Hemisphere)

Impressive consistency in temps between yesterday (10.9/3.3°C) and today (10.7/3.3°C), despite a completely differnt weather: yesterday alternated between sun and showers whereas today was overcast with light rain in the evening.

We had 11.2/4.6 yesterday with sun and showers, and 11.0/4.1 today with sunny skies.

storm total; a bust here, 2+ feet out in the Berkshires. North Adams got 30 inches!



hills have 4-5 feet deep snow. We had a dry slot of air aloft, keeping the snowfall rates 0 or low. Only came down hard around 8-9 pm, with strong winds.

there's this but it shows lower for the Berkshires than the NWS Boston map

upper level low in the region. Discussion from Mt. Washington


An upper level low will remain parked over the northeast for the start of the weekend steering a pair of surface lows around the region. The first low will move north across Maine Friday prior to weakening late in the day. Lingering low level moisture will bring continued summit fog, clouds overhead, and occasional upslope snow showers. Overnight, a secondary low will form offshore and be drawn up towards the Canadian Maritimes prior to retrograding Saturday. As the low approaches, bands of snow will rotate in bringing continued snowfall for the higher terrain. While winds will weaken with Fridays low, as the secondary low moves north and west on Saturday, a tightening pressure gradient will set up resulting in increased winds. The easterly flow from Wednesday and Thursday resulted in large snowdrifts on the western slopes of the mountains. Since then, winds have slackened and shifted to a westerly flow. As a result, when winds start to pick back up, all of the snow that has fallen and will fall will be whipped up and driven eastward.

was snowing for half an hour, gloomy the whole day. Clouds supposed to break a bit tomorrow, but the Whites look mostly cloudy next week as they're more prone to cloudiness. Here's the upper level right now

Next few days look fantastic in Vancouver. Lows near freezing with highs climbing over 15C by Sunday and Monday.

Same here! Bugger both of us sideways...

Marchuary continues with 1-2 C highs, snow showers and overcast forecast until Friday. Then we have 2 pitiful days of 8-9 C and rain and then right back down again. 

This is is the by far the shittiest “March” I can remember:

•2017 was bad, but had a few days of interesting cold, a few days in the 10s C and was relatively variable 
•2015 was worse, but at least that had a bunch of days of 7-10 C.
•2014 was very cold at first and set the March record low and managed to have 4 days over 10 C so it was at least interesting with a few mild days
•2013 had several cool, boring periods of 2-3 C but also reached 18 C one day

None of them did isn’t even reach 6 C in the first 17 days, recorded a few days over 10 C and had some interesting cold rather than useless, unpleasant, boring cold. 

The highs so far this month:
6, 1, 3, 1, 0, 4, 1, 3, 1

And in the forecast:
2, 3, 1, 0, 3, 3

The astronomical seasons are actually a better fit for the last 8-10 years. Spring starts in late March now and Fall doesn’t start until late September.

71F with a 62F dp and threatening rain. Low was 57F this morning and high this afternoon was 74F
