By the way, today I gave in and turned the air conditioner on for the first time since November 7. I look forward to turning it back off by the end of the month, and hopefully keeping it off for a couple more weeks.
Snowfall warning issued for Vancouver. 10cm(4") for the city through tomorrow night with higher amounts in the suburbs. A local meteorologist is thinking 20cm(8") is possible for some.
The snow level is expected to remain below 300m into next Wednesday.
2-6pm Loop. with storm reports. Looks like 4-6" on the ground in central NY after being in the 70s. Wow. Greylock must have gotten a few too!
oh nothing that big. enough to cover the ground barely. too light to be a nuisance but enough to cover the brown vegetation. Probably will be gone by tomorrow afternoon
You can instantly see the differences and perhaps this is "ONE OF" the reasons we had squall line last year.
Last year Cold air was digging south more as the ridge left and created a sharper gradient and more instability. This year it's kinda flatter because its digging out west
SouthEast Ridges are stronger than full Eastern Ridges IMO. They are harder to break down and move.
Then you have the Jet Stream winds, Sub Tropical Jet stream moisture, instability, out of time now.
Thanks for digging up all those old posts and maps! Figured it had something to do with a steeper temperature contrast.
Another one of my more surreal weather experiences as a child was March 7-13, 1995. On March 7, the high temperature in Pittsburgh was 73°F, and a winter storm watch was in effect. It was later upgraded to a winter storm warning, and the temperature on March 8 plummeted from 65°F just after midnight to 19°F just before midnight March 9. Pittsburgh received 6" of snow that day, and the temperature didn't go back above freezing until the afternoon of March 10. In fact, the morning low temperature on March 10 was 8°F. Even crazier is that the high temperature on March 13 was 76°F, which was tied for the warmest temperature in Pittsburgh that month.
Daily summary (March 7-13, 1995)
High temperatures: 73°F, 65°F, 26°F, 35°F, 58°F, 68°F, 76°F.
Daily mean temperatures: 60.5°F, 42.0°F, 19.5°F, 21.5°F, 40.5°F, 52.0°F, 55.5°F.
Departure from normal daily mean temperatures: +24.2°F, +5.4°F, -17.4°F, -15.8°F, +2.9°F, +14.0°F, +17.2°F.
I remember that cold snap and the heat wave that followed it, it was not quite as warm as March 2012 but very warm for March nonetheless. We also had a big thaw earlier in January 1995. The next winter was colder particularly in December 1995 and the early part of January 1996 but there was then another thaw. The January 1996 thaw was a disruptive and destructive event unlike the previous year's thaw with deep lows barreling through on January 18, 22-23, and the 27th if i remember correctly. The January 18th 1996 storm was particularly severe with heavy rain, hail and thunderstorms, made worse since a foot of snow had just melted over the previous couple days. Flooding caused my town's schools to close for over a week. At the beginning of February an arctic outbreak occurred and all of the floodwaters that hadn't fully receded froze over creating huge sheets of ice on the streets.
That cold was super impressive, but the fact of the matter is much of the Southeast will wind up with a winter near or warmer than normal because of how much warmth there's been this February. In Oklahoma we didn't have the same level of extreme cold, but we also haven't had the same amount of extreme warmth, so the winter will likely end up below normal for temperatures.
Also, unless we can eke out another 1.6" of snow in the next six weeks, this will be the first winter in OKC to have had less than 2" of snow all cool season and below normal temperatures in December, January, and February. That's a rather depressing first to set.
Yeah, this was a short but intense winter for us. I consider it winter here when the 21-day running average (centered on the current day, also including 10 days before and after) drops below 46.0 F / 7.8 C. The average winter is November 30 - March 1 (92 days). Data is for Nashville, TN.
Winter 2017-2018 was December 2 - February 9 (70 days), but the running average dropped to 29.3 F / -1.5 C on January 8 (that's the average for December 29 - January 18). That's the 20th coldest average of the last 60 winters, i.e. colder than 2/3 of all winters ever get.
The last time the running average dropped that low was 2010, with 27.9 F / -2.3 C on January 4.
Coldest running averages since 1959 (one per winter, total of 60 winters)

Love all the snow tonight. Actually looking forward to shovelling it. What's nice about MN is there's enough sunny winter days that we aren't slaves to the shovels.
