At least 10 lightning strikes seen

18.8.2022 at 17.25 - 18.45 - Lempäälä (IV)
Esa Palmi, Ursa (Länsi-Suomi)

The most active ground lightning I've seen this summer. The rumbling was constant and lightning often struck the rainless area. Fortunately, there were sometimes Edesjonki-like filming locations.

At least 10 lightning strikes seen

17.8.2022 at 16.05 - 16.45 - Ylöjärvi, Kuru (III)
Esa Palmi, Ursa (Länsi-Suomi)

At the leading edge of the day's thunderstorm band in Kuru. The lightning inside the cloud was the strongest of the summer, and earlier in Ikaalis you could also see beautiful ground lightning while driving a car. Trees also fell on the road behind the car.

Even though the thunderstorm day was quiet in Pirkanmaa, the cell that rumbled south of Tampere for a while in the evening was visually one of the finest in recent years. The cloud rose to more than 10 kilometers in an instant, until it died away as quickly as it was born. The anvil alone remained floating in the sky for a long time. The last pictures from the Tampere side.

At least 5 lightning strikes seen

12.7.2022 at 19.05 - 22.20 - Iitti, Urajärvi (III)
Esa Palmi, Ursa (Länsi-Suomi)

The traditional Finnish fate of a storm enthusiast. You are in the perfect spot, the thunder coming your way looks big and powerful but freezes completely about 50km away from you. After that, a smaller thunderstorm cell appears right next to it, and the rain and a couple of nearby lightning drives you away from the shooting location. On Tuesday, all the best thunderstorm events stayed at the eastern border, but chatting with fellow enthusiasts and seeing a few flashes of lightning put a positive tone on this trip.

Arcus cloud

9.7.2022 at 16.00 - 16.08 - Kankaanpää (IV)
Esa Palmi, Ursa (Länsi-Suomi)

The west coast thunderstorms continued, but the continuous rain made tracking more difficult. I started to drive towards a rainless section inland, where the models did not show as good values as the Selkämere or the coastline. It was quite a surprise, when there was a spectacularly rotating wall cloud at the front edge of the front near Kankaanpää, and the whole convection band was preceded by a cumulonimbus cloud. For myself, one of the best wall clouds seen inland. Otherwise, there have been a lot of rolling clouds today, especially on the coast, and several water statues have been seen on ...

9.7.2022 at 14.10 - 14.30 - Eurajoki, Luvia, Laitakari (III)
Esa Palmi, Ursa (Länsi-Suomi)

The day's storm photography trip went to the west coast, where, according to the models, there were thunderstorms coming up from the sea throughout the day. At first, in Pori, I heard a distant rumble from the sea and I also saw a few distant flashes of lightning. When the rain started to mess up the visibility in Pori, I drove to Luvia, towards which there was a stronger echo of rain and lightning coming from the south. Shortly before the observation site, the cumulus cloud began to separate from its parent cloud and the approaching thunder band weakened.

In the morning, the thunder rumbled on the side of Parkano, filmed with a drone. Unfortunately, continuous rain everywhere prevented better filming.

Esa Palmi, Ursa (Länsi-Suomi)

On the borders of Parkano and Ikaalinte in Vahojärvi and in Sisstö, a forest felled by a rapid flow. The area is kilometers in length. The fall flow was on 2 July 2022.

At least 10 lightning strikes seen

2.7.2022 at 18.35 - 20.00 - Kauhava (III)
Esa Palmi, Ursa (Länsi-Suomi)

For the first time this summer properly on the road. The early summer has been really miserable in terms of thunderstorms, so Saturday's conditions gave me the motivation to go for a little longer ride. The clouds got high, but most of the lightning strikes were high up in the cloud. This one knew constant rumbling, but ground lightning was less frequent. There was nothing particularly showy, but Ostrobothnia's unusually high humidity for Finland's level and a suitable temperature drop caused cells to be born no matter how much during the day. I started the day with high convection...

At least 10 lightning strikes seen

15.8.2021 at 00.50 - 01.40 - Kurikka, Jalasjärvi (III)
Esa Palmi, Ursa (Länsi-Suomi)

The finest night thunderstorm of summer so far. I tried to find a decent clear spot and one was found around Jalasjärvi. The thunderstorm of the coast was still far away, but the towers were well visible and flickered constantly. The place would have been perfect in terms of direction of movement, but unfortunately the sky was quickly filled with other clouds. However, these constantly flickering "bulbs" are always great to follow.

Esa Palmi, Ursa (Länsi-Suomi)

The best cell of the day on the west coast. Cycle forward from this far to the north of Kristiinankaupunki. Tops well over 10 km.

Esa Palmi, Ursa (Länsi-Suomi)

High-rise towers near the west coast. A rare chase day in Finland because there was no other cloud cover in the sky. Only 1-2 thunderstorm cells at a time, so tracking was easy. This happened to pound for a while around Merikarvia. The cell shown in the picture on the right cycled longer on the sea.

At least 10 lightning strikes seen

23.6.2021 at 18.20 - 18.40 - Varkaus (III)
Esa Palmi, Ursa (Länsi-Suomi)

I drove in front of the thunder system that rose from the south to Savo hopefully, because according to the models and the satellite image, the thunder would arrive in an area where it should intensify even more. However, the opposite happened and the eastern edge remained weak despite all expectations. In Varkaus, behind the lake seen in the video, a resounding to the right began to form and a sharp ribbon intensified. Personally, I fell under the lightning of the weaker part that rose very quickly on Varkaus. Lightning was sometimes active in the core of the cloud, although mainly only flash...

Arcus cloud

23.6.2021 at 14.45 - 14.55 - Mäntsälä (II)
Esa Palmi, Ursa (Länsi-Suomi)

The thunderstorms of the early part of the week have passed thanks to the rest of life, so on Wednesday I had to try to see even something. The spectacular avalanche cloud seen on the south coast weakened as it went inland. This is often the case when a system-class thunder strikes inland. Usually later inland the spectacle begins to recover. The speed of the system was wild, probably about 80-90 km / h.

During the holiday trip, thunderstorms accidentally developed in front of the beak. These were the first cells to eventually develop into a thunderstorm system that swept over Oulu. The rain foot was just fine.

Hail in the summer season

8.6.2021 at 16.30 - 17.55 - Kangasala, Sahalahti (IV)
Esa Palmi, Ursa (Länsi-Suomi)

The forecast showed a so-called pop-up, with upstairs winds being very moderate and thunderstorms moving slowly. If individual cells happen to merge appropriately, there would be opportunities for a more linear thunderstorm. At first, thunderstorms across Pirkanmaa wanted to go out as quickly as they had. When I was in Valkeakoski in the afternoon, both in the south around Hämeenlinna and in the north around Kuru, the strongest thunderstorms of the day had developed. Both were multicellular thunderstorms. After the draw, I headed north and it was just a good choice. On Sahalahdentie, I reached...

17.5.2021 at 14.30 - 15.00 - Tampere (II)
Esa Palmi, Ursa (Länsi-Suomi)

The deaf strip rising from the south rarely flashed and some kind of avalanche cloud was visible at the front edge. In general, the day was a weak thunderstorm in Pirkanmaa compared to the wind.

15.5.2021 at 16.25 - 17.35 - Kauhajoki (IV)
Esa Palmi, Ursa (Länsi-Suomi)

The summer 2021 thunderstorm season opened. The models looked like the so-called. shortwave to be on the southwest side and intensifying upstairs winds significantly. This would know harder thunderstorms if only it were clear and the sun could properly intensify the occurrence of thunderstorms. However, for a long time Cloudiness was a nuisance, when the thunderstorms that arose were very mumbling, but still yielded a few decent lightning strikes. This said there was enough power upstairs. My time when I watched mosses in Northern Pirkanmaa and Jalasjärvi was drawn to the clearer area to the w...

The sun was visible for a long time and along the day handsome side suns.

Glory on air

Esa Palmi, Juha Palmi, Ursa (Länsi-Suomi)

The sun appeared in Pirkanmaa after many months. When Dronen was flying, gloria was stored in the camera. I myself have seen this phenomenon once before in the Lapland fell.
