By some small added amount... (if otherwise determined less significant, notwithstanding) this heat wave in N-W Europe is plausibly made fractionally worse by the fact that it's straddling the Solstice. The idea being obvious, the sun surround this week to 10 days perennially reaches it's most intensity relative to all N. Hemispheric latitudes. July heat waves are within the solar Max period of the year, ~ May 10 to August 10... Not sure if this is a threshold argument, to be fair. Like it doesn't matter for solar flux variances when above a certain value, as long as the region is above that seasonal value, the heat response is the same. I'm not sure that makes physical sense because you are either dumping more, or less actual solar radiation into the system - The other complexity is 'prompting' overlapping with circulation modes of mid summer that are concurrent by July 20th.. Prompting comes from a kind of "non-Markovian" aspect of the hemisphere (Non-Markovian refers to systems where the future state depends not only on the current state but also on past states, indicating the presence of memory effects in the dynamics of the system... ) So, that kind of trades off a slightly lowering solar rad count for the fact that the system is bias to get back to warmer states. The circulation mode addition is that the normal seasonal expansion of the HC and polarward retreat of the westerlies --> the apex in seasonal-climate for heat reaching it's farthest N latitudes. If 1 and 2 are constructively interfering ... it may be worth it to take a linear look at the statistics over the years, and see if there is a tendency to heat repeating when May/June are significantly above average. That's the science approach... intuitively? mmm we're doing that ( plausibly) when holistically ...the world is constructively interfering with any excuse to be warm at all. All of which begins to fade off circa mid August. At which time solar dimming becomes significant enough that it just doesn't add as much, or enough to recover a hot hemisphere - prompting can't actually do it alone, and ambient troposphere begins to shrink (albeit less coherently at first) from losing diurnal thermal pressure. So a short version take away... You know, I can already see that D4 the the heat has relaxed due to downward/relaxation in the present circulation mode from the middle Atlantic Basic to Scandinavia. However, all the ensemble main sources, EPS/GEFS/GEPS are more and less coherently already showing by 200 hours that a new ridge may be formulating W of the Iberian Peninsula. That essence tends to presage a correction as the times near to go ahead and balloon that feature N-E to engulf as far N as the lower B.I region ... perhaps a resurgence is in the making.

Last year at this time my yard was full of lantern flies. Now none. Did our brutal winter destroy them?

Why is the board running so slow lately? It takes forever to load and open

Lol…until further notice

Another perfect morning

!!

Can't remember a June like this with low dewpoints, a refreshing breeze, and clear, blue skies. Get outside everyone!

What an absolutely glorious morning! 71 and while the humidity is at 66 sitting out on my deck which is in shade for the morning I am having some breakfast and working on my meal plans.

I was on the phone with someone from the UK earlier today and he said that it has been so hot that most people are not going to their offices because most of the offices in the UK don't have air conditioning. He also said he was working from home in front of the only small fan in the house, and that most homes in the UK don't have air conditioning.

Ended up with 2.20" ST putting June at 3.07".

"The big numbers in that graphic are obviously due in part to AGW short periods of records. " see how that works ?

End of August 2003. End of July 2019. The old heatwaves are being ridiculed when we're only in June! ➡️France has just experienced by far the hottest day ever measured since at least 1900, with an average national temperature around 30°C. ➡️With spectacular temperatures of 44 to 45°C across several French departments. ➡️131 absolute records broken. ➡️44 million people are overwhelmed by a red "heatwave" alert. ➡️Tomorrow, with the wind dying down, a "foehn wind" episode or so-called "flash drought" is expected in the Centre-West region, with a fire risk index at "extreme" to "very extreme." We've just rewritten history. Before tomorrow, when it could get even hotter.

2 day totals. I was able to get my report in for this one

I had a low of 53 this morning. What a way to run Summer in the Mountains!

Got another hundredth of an inch yesterday for a 0.24" final and 2.80" 2-day event total. My high was 71 after a low of 64, and the drier air is trickling in. Currently a sunny 70 with dp 61. I've been following that Limerick site one as I figured exactly why the location was picked. I remember my senior high school physics class taking a field trip to Limerick back in 1979 while the plant was still under construction. I think the cooling towers had recently been completed. The PECO tour guide told us that once the plant came online, the average electric bill would drop to $3/month.

Plenty of lows in the 50's across the area this morning with the lowest being the 50.0 at the Warwick DEOS. Today will be our 9th day in the last 10 with slightly below normal temperatures. Great weather through Thursday before rain chances increase again by Thursday night into Saturday morning. We should slowly warm up next week to above normal temperatures as we close out the month of June.

The LI crew would really be complaining if this was a snowstorm.

Hoping to reel a storm or two in today or at least a nice show in the vicinity

High risk not issued very often this far out.

Have an event Saturday morning at the National Zoo. Hoping this is delayed a day.

70 / 57 great one on top nicest day of the next 3 with clouds returning Thursday and showers/storms Fri and a cloudy wetter Saturday. By Sunday we dry out and the ridge is building to our west into the Mid West > 594 DM. The period 6/29 - 7/4 overall warm to hot, some tendency for NE / onshore along the shore/beaches with strongest heat inland. With a small pull back then overall warm to hot beyond there in the 7/7 - beyond.
