Summer for Northwest Europe is over as much cooler air and wetter pattern develops next 10-15 days!
Yeah, the GFS shows that cool pattern until the 15th at least. The area is rather big, all the way from the Bay of Biscay to the Alps, east to Warsaw and up to Central Scandinavia. But as those departures are what they are, the temps will be still in the comfortable 68-72F zone, which is summer for Northwestern Europe. I still have high hopes for the latter half of August and I hope those temps recover.
Speaking of 850s. I think this is the lowest freezing line I've seen so far since Spring. I believe models show it touching the Northern tip of Minnesota tomorrow. Even this morning temps are in the 30s and 40s there. So more 30s in store for them if the temps aloft drop that to freezing..
I dont care if it's not over me, I love seeing this happen.
BTW.. thats an Upper Level low there causing this cold pool.

A few cooler than average days for the NW of the UK, but certainly not wet. It's actually a high pressure pattern bringing NW'ly winds, so there will be very little rain at all, there isn't any appreciable rain in my forecast and I live in one of the wettest parts of the country.
I wish there was going to be low pressure and wet weather actually, it is more interesting than this boring cloudy/partly cloudy "nothing" weather, and there would be more chance of thunderstorms of which we have no chance of under this cold maritime high pressure crap.

It's neat that the 850's will be below freezing, even if surface temperatures are well above freezing. That freezing line dipping into the northern tier is a sign that autumn is approaching .
Meanwhile, check out this huge cool pool that will be present today in the central U.S. 21F below normal in Kansas in early August is quite unusual, although it has been relatively common this summer. The interesting thing about it is the stark contrast between the 70's forecast for Kansas and the near-100F temperatures that are blanketing Texas. In summer one usually doesn't see that much of a contrast in that short of a distance, at least on a large scale (barring random thunderstorms and the like).
Without getting too technical, just want to bring up something I'm seeing. Pretty interesting!
#1. Trough and Upper Low over Bering Straights/Alaska happening is setting the stage for a locking pattern and will lead to a ridge in western U.S which means eastern trough. This time of year its not amplified. once fall/winter comes around and they get amplified with this pattern....wow
#2. It is starting to look downright cold north of the Hudson Bay.
#3. These 2 images are the 500mb height anomalies for Aug. 13th and Aug 18th from GFS. Notice 3 things...
A. The extremely negative anomaly near the pole.
B. The below normal heights going underneath the above normal heights in western Canada. This is helping keep temps in check across the U.S!
C. Notice what happens after, Canada goes above normal at 500mb and a cold pool gets stuck underneath in the U.S. That spins and stays until it weakens and shreds apart. Fascinating stuff.
