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.

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.

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.

Esa Palmi, Ursa (Länsi-Suomi)

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...

Arcus cloud

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.

Arcus cloud

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...

One halo form

28.1.2021 at 15.00 - 15.25 - Ylöjärvi, Kuru (I)
Esa Palmi, Susanna Palmi, Ursa (Länsi-Suomi)

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

Glory on air

9.1.2021 at 14.00 - Ylöjärvi, Kuru (IV)
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.

At least 10 lightning strikes seen

25.9.2020 at 18.30 - 19.00 - Kurikka, Jalasjärvi, Saarijärvi (III)
Esa Palmi, Ursa (Länsi-Suomi)

The set, which was one of the top 3 thunderstorms of the poor thunderstorm, appeared at the end of September. The constant rumble and flicker continued in Ostrobothnia for a while. The lightning once again remained deep inside the rain, the edges sparkled. This can again be hopefully continued towards next summer. If this time or not :)

At least 10 lightning strikes seen

24.8.2020 at 23.00 - 03.30 - Porvoo, Emäsalo (III)
Esa Palmi, Ursa (Länsi-Suomi)

The forecasts were strongly in favor of the sea gulls in the Gulf of Finland, so a trip to the south coast and the cliffs of Emäsalo in Porvoo to watch the natural play. Together with Eero Karvinen and Markku Ruonala, we watched the cells flashing at sea for hours. The rumbles were heard from lightning locations up to 70-90 km away, so the sound world at sea is quite different from that on the mainland. Despite the long thunderstorms, the trip and place were worth all the experience.

At least 10 lightning strikes seen

22.8.2020 at 21.15 - 22.00 - Kauhava, Alahärmä (IV)
Esa Palmi, Ursa (Länsi-Suomi)

Stunning flash show in the Power Park parking lot in Alahärmä. The cluster of cells rising from the south intensified at these points and flickered in the cloud every few seconds. I have not seen such an active twilight / dark sparkle since 2012. Long after this, glimpses were seen from many directions.

At least 10 lightning strikes seen

22.8.2020 at 17.30 - 19.10 - Kruunupyy (IV)
Esa Palmi, Ursa (Länsi-Suomi)

The models showed the encounter of Cape, shear, temperature transmission and humidity in Ostrobothnia. So the car cam towards the expanses. The time of waiting was long, because despite the sweating air and the tearing of the cloud cover, nothing miraculous was to come. Until finally in the evening around Pietarsaari and Kokkola exploded rapidly. Although the clouds were largely muddy, there was room for a rotating cloudberry and a microburst inside the cloud. The thunder lasted for many hours, so this was quite a rarity then in the 2017 Rapid Heavy. The ground lightnings were not really visib...

19.8.2020 at 18.35 - 18.50 - Tampere, Kämmenniemi (III)
Esa Palmi, Ursa (Länsi-Suomi)

Warming of warm air mass without shear. The cell that thundered in Kämmenniemi near the center of Tampere was well visible and eventually passed a few kilometers away. Lazy lightning, but one positive ground lightning struck many miles outside the cloud about 800 meters away. The most dangerous phenomenon in this hobby.

Esa Palmi, Ursa (Länsi-Suomi)

From the short chase of the evening home and I saw that a small cell was still developing near the cottage. A trigger towards the cloud and one thunderstorm happened to be heard. The line was also left on the cell at sunset.

Other special clouds

20.7.2020 at 21.03 - 21.06 - Jalasjärvi (III)
Esa Palmi, Ursa (Länsi-Suomi)

Such a thing arose in the place of the avalanche of a dead thunder cloud. Likely to meet Asperitas requirements. Interesting ripple, less often myself become so clearly received.

Arcus cloud

20.7.2020 at 19.10 - 19.50 - Kankaanpää (III)
Esa Palmi, Ursa (Länsi-Suomi)

It feels like you’re in exactly the right place for a thunderstorm and just turning your way towards chase fields. Then there is the road construction site and a 15-minute wait. After this, after the lead car for 10 minutes and crowned by the hose, the first drive after road work is a maximum of sixty. You can get pictures from the window on your mobile phone, but you could have tried to shoot lightning and the shape of your whale`s mouth better. Still, this summer a few extra flashes and shapes in the clouds bring a lot more joy!
