Localized thunderstorm happened in Washington County, OR today. Completely unforecasted. Now there are severe t-storm warnings in southern and eastern Oregon.

A storm just south of Turin in August 11th, it caused quite a lot of damages (broken roofs, fallen trees, damaged cars, destroyed crops etc...)

We had some more thunderstorms pass through this past week, that's fairly late in the season. We don't normally get much in terms of storms in mid August. We've also had stormy-looking convective clouds that are normally associated with humid heat, also uncommon in August. Cool stuff.

Rain this afternoon following a very warm August day (26.4C in the city and 25.4C at Jandakot). Couple of rumbles of thunder around 4:30-5pm but nothing too serious.  |

A massive band of thunderstorms is making its way toward the city right now. We've got higher temperatures and humidity than average at the moment so I guess that's helping to fuel the storms. I thought for sure storm season was over for the year but I guess I was wrong!

This is a picture that is circulating on Facebook since yesterday, it's a small and localised rain shower (or whatever it is) just south of Turin. The picture was taken just a few days ago.  |

This is not the radar you'd expect to see between Gotland and Latvia on a 14 October night...
Earlier tonight it also moved across Southern Sweden and the Scania/Blekinge regions having been formed in the crossover of the Öresund strait between Denmark and Sweden. Highly unusual in mid-October for a sustained thunderstorm to actually take hold in Sweden. Usually it stops at virtually a single lightning strike in the peak convective area.
In August, this would've been a minor one, but for October it's actually really large by national standards.

Quite a sizeable thunderstorm near 11 am today between Stavanger and Bergen on the Norwegian North Sea - at 59°N on 26 October. Really impressive to be honest. Convective energy usually is dead this time of the year this far north. Did you see this Nidaros ?
Getting abundant rain in that part of Norway is no surprise, but lots of lightning near Halloween wouldn't seem like a common thing to me.

No real thunderstorms here at this time of the year anymore, however last night I had a dream that I was in a highrise apartment in Windsor, Ontario and there was a massive storm cell rolling across the Detroit River with so many flashes of lightning that it was like a really fast strobe light going off and several claps of thunder so loud they shattered all the windows. I don't really have that many weather related dreams but this was a pretty epic one  |

My home region in Italy is at the end of a weather alert (started on Friday late evening) for the heavy rain and the associated river flooding, landslides and avalanches (higher on the mountain) risk. Here there is the map showing the total precipitation of the last 48 h (so covering the most of the event)  There were actually several criticises, in particular in the southern part of the region where some large rivers flooded and some major roads were interrupted.  ^ the Po river in Turin, all the "Murazzi" (river banks) are flooded since early in the morning. But the city itself should not be flooded There are also some other points were the Po rivers is actually flooding into municipalities, the main example up to now seems this one, Cardé:  While the most extended flood is near Alessandria, around the Tanaro and Bormida rivers.    One of the most worrisome damages seems the one of the motorway that from Savona (Liguria) goes toward my region, where a segment of the motorway was dragged down by a landslide near the municipality of Altare  Different prospective  The issues were somehow limited by the fact that, often, the snow line was much lower (some hundreds of meters) than in the initial forecast, so in the mountain municipalities is actually snowing a lot instead  ^ Artesina, a ski place in the SW of the region, those plants are probably at about 1500 m or so. (The comment on the picture says: " A typical situation for Mariolino (the guy in the picture, I suppose) 😂" |

North Atlantic off Ålesund in Central Norway (62°N) at 13.30 local time 12 December:  That many thunders near Christmas is definitely not something you'd expect! Sure, winters are mild and average about 5°C highs but this is still remarkable. |

Yahya Sinwar Thunderstorm days in Richmond vs Raleigh according to NCDC normals. It looks like they're using different periods of record, but as you can see the difference is actually greatest in July.

Never thought I'd be posting on notable lightning activity in February. Meteoman will be happy.  |

37 mm downtown! This breaks a two month drought. Nothing here so far but there could be.  |

 This map counts a thunderstorm day if there was a single cloud-ground flash within 10 miles (16km). The source has a lot more information, including explanations of how the data was generated, and a few more maps. One is the density of lightning flashes in flashes per square km per year. The peak is 16 in Florida. I'm in the 2-4 range on that map. Another map has a count of thunderstorm days, but with a smaller range, the flash must be within 5 miles (8km). On that map, I am in the 27-36 range, and the peak is 90-99 in southwest Florida.

According to that map, 93% of the US gets more storms than Renmark. But then again, so does 93% of Australia.

I have found thunderstorm days data for Frankfurt Airport 
Average thunderstorm days per month 1981-2010:
Jan: 0.3 Feb: 0.5 Mar: 0.9 Apr: 2.1 May: 4.8 Jun: 5.6 Jul: 6.0 Aug: 4.8 Sep: 1.6 Oct: 0.6 Nov: 0.3 Dec: 0.2
Pretty pathetic overall. Most days with thunderstorms per month ever was 13, recorded three times in August 2006, July 2014 and June 2016. I remember Aug 2006 and Jun 2016 very thundery, though I have no weather related memories of Jul 2014.

Had the first thunderstorm of the year yesterday.
About a km away from me a huge amount of hail fell, at least an inch. Thunder sounded evil, like a long high-pitched crack.
