That's kind of neat, to see a lot of snow in the Summer. I assume you visited some cold-summer locales and/or locales that hung onto their big snowpack . Perhaps you could elaborate some more on that.
I saw a lot of snow this summer, much more than this winter. I could post some more photos but they belong in the summer thread.
One more "arctic blast" day; we haven't had one since 3 weeks or so. High of 25°F, well below average (38°F), but the low is only a bit below normal. It's 15°F out right now.
Anyone have an idea whether there might be any more cold snaps in the next few weeks? This cold snap was much weaker than some of the models and previous forecasts showed. Snowstorm was a complete bust as well. I'm thinking if another cold blast doesn't come in the next 2 weeks; that'll be our last one of the winter, as the sun will be getting noticeably stronger soon.

I was impressed because the temp on the summit Mt Washinton must be close to the temp of the air mass (850 hPa temps). The fact it cannot trap cold air thanks to temperatre inversions makes it even more impressive than Berlin's record to me, even if it's quite a bit higher. Let's say it was 10°C colder than the 850 mb temp, that would still mean a -35°C air mass. And given the windy reputation of this moutain, it may have felt much more brutal than a "plain" -45°C.
For example France's coldest town is only 930 m (3,050 feet) high and its record low is only 2°C short of Mont Blanc's one (15,000+ feet), -41°C vs -43°C.
Can explain to me why that's impressive? So 850 mb is the pressure at the summit of Mt. Washington. Ok, I think I got it. The -45°C temperature at the summit means the air mass itself must be very cold while -42°C valley temperature is the effect of radiational cooling and temperature inversions.
I didn't realize mountain and valley lows matching were that usual, especially for much larger mountains. Right now, it's -26°C on Mt. Washington with a NW (NW always brings the coldest air) 109 km/h wind gusting to 117 km/h. This is interesting way to see how the temps change with altitude:

850 mb is the mean pressure about 5,000 feet above sea level, so a bit lower than Mt. Washington. The summit must be a few degrees colder than this level. I mentioned it cause 850 mb temps are shown in model maps.
These are brutal temps in open air. Only limited stretches of the Arctic basin can have such temps at the same time. So seeing these and at Mt. Washington's latitude is quite impressive to me.

When it's calm and clear it's not unusual to have 0°C at 1500 m and -5°C at 0 m here, even -10°C when there is snow on the ground. For larger mountains, I'm sure Mont Blanc is always colder than nearby Chamonix, 4,000 metres below. Inversions have their limits.

Yes, 19th-20th should be the next one. If anything, whats going to happen is, instead of having fridgid winter temps for 2-3 weeks straight, March April could give us weeks of 30s which would be below normal for Spring.
As far as the snowstorm bust.. It didnt happen because dry air got into it AND the system stayed too far Out to sea. You might find it interesting the GFS model had it correct 4-6days out ... then all models had it closer to coast by days 2-4(thats when we all mentioned snowstorm because thats what they showed) then day before they showed it back OTS and less precip.
Today was a wintry day here. Windy with a low of 16 F and a high of only 30 F. Some sun most of the morning, but then it turned overcast and snowed for an hour so. Had a nice coating. I was working outside on and off today and I thoroughly enjoyed the brisk weather. Of course several hours in it wouldn't have been ideal since my eyes would have been tearing up (a nuisance I'm still willing to put up with!).

^^ Today was a bit similar, low was 15°F and high was 34°F. Though I fear it was the last wintry day of this winter.
