2019 Summer Discussion (Northern Hemisphere)

It's still August, I'm surprised you haven't had 30C in September. We've even had 29.5C in October.
It always surprises me how cool September is up there in comparison to July and August. September here is generally as warm as June, and is often much better.

Damn, a 14 C difference is insane! I think I may have seen a difference that big between NYC and inland, outlying areas in NJ and CT, but I've never seen it for here. Looking back the past ten years, the biggest difference I could find was a 10 C difference between Reagan (DC proper) and Dulles (outlying areas) on February 24, 2015. Reagan had a -10 C low while out here had a -20 C low! Impressive difference, but it ain't 14 C lol. Maybe taking into consideration even further outlying areas like Front Royal and Winchester up here there could be a difference that big. It's interesting in spring, DC proper blooms like three weeks ahead of out here. At least this past March, lots of mornings which were solid freezes out here (like in the -3 C to -5 C range) were 2-3 C lows in DC proper. They were bursting in bloom in the second half of March while out here was pretty much completely bare through the end of the month.

I wonder what's the largest UHI ever recorded, I wonder if a 20 C difference between an urban station and an outlying location is possible in the same geographical area. I would guess if the rural location is in a frost hollow it could be possible.


Kind of a warm-ish and humid-ish evening here, at least compared to recent weather. 23 C with an 18 C dew point. Still quite pleasant though.

Warm and humid this morning compared to the last few days; 70 F (21.1 C) with a 67 F (19.4 C) dew point. Today will be quite nice, sunny, low humidity, high predicted at 82 F (27.8 C).


We're getting some nice and cool nights the next couple of days, 61 F (16.1 C) for tonight and 58 F (14.4 C) for tomorrow night.

Almost time to close this thread up

Today hit 80+ for the first time since last Thursday, quite remarkable not to hit 80 F for almost a week in August! Had quite the downpour today too.


76 F with a 68 F dew point this evening here, not terrible, but not good either.


Supposed to drop to 60 F (15.6 C) tonight and 57 F (13.9 C) tomorrow night though! Nice and cool nights. I'm guessing there will be a good drop in dews later on to aid in the cool down tonight.

Had a pretty good thunderstorm this evening; the best lightning I've seen this summer! Some close range strikes.

Storm with flooding rains at the end of July probably had more lightning but I didn't really get to watch much of it.

That 61-90 average spot on the map right over Umeå is a proof that Umeans are all a bunch of cucks.



So far this summer



This is for 2019 so far. You guys can all suck my dick 

The newest drought monitor update has us in the “abnormally dry” category. First time in some level of drought since last July.

It’s been a pretty dry August with only 1.74” (44 mm) so far. I like the dryness but I wish that rainfall came as thunderstorms not drizzly rain.

I’m hoping we can get into actual drought next week but it looks like we’ll be entering a wetter pattern.

For a warm, dry summer—which is what I root for—it’s been as bad as it could be. The positive anomalies are coming from consistent slightly above average weather so it’s been both extremely stable and there’s been no heat. It’ll end up above average but all heat stats like record high, days over 90, days over 30 C, etc. will end up below average. With boring as fuck temps, there could at least be good storms but there’s been very few thunderstorms and all the rain is just plain old moderate rain.

69 F (21 C) with a 58 F (14.4 C) dew point here, it's cooled off by 11 F (6.1 C) in only the past hour!

Unfortunately, for whatever stupid reason, NWS took a giant shit this morning. I very clearly remember seeing OBS for 4-6 am but it's not showing up on there, and of course it fucked up the 6-hour readings, so no way of telling what the real low this morning was. Not the first time it does that either.
