At least 10 lightning strikes seen

3.7.2022 at 11.00 - 13.00 - Nurmes (IV)
Eero Karvinen

The frontal zone, together with the high moisture in the lower troposphere and the cooled middle troposphere, created a suitable base for thunderstorms. Thunderstorm development started in the morning hours near Kuopio, rapidly intensifying from small cells to MCS. Pictures taken from the observation tower in Ylä-Valtimo. The lightning was mainly cloud lightning, but some really nice ground lightning was recorded on the camera. Shot using a trigger. In the quadrilateral, the cell shortly before the crossing. The development of convection was very fast.

A few gusts, a few flashes of lightning and a lot of water, that's what this thunderstorm offered.

Strong thunder crossed Tampere, accompanied by heavy rain and torrential rain. First time in my life when I bonga super cell thunder and feel its power.

Mavicci was on duty for a long time making videos, but the lightning must have struck inside the clouds, because despite the constant rumbling, I couldn't get them in the picture. I was expecting funnel clouds from the south side of the city, but they didn't come either. I had to settle for messy rain walls this time too :(

In the morning, thunder came from the sea within earshot sometime before three, it was still an hour before sunrise but it was bright, lightning was visible at a steady pace but rarely, I managed to get one on video. The show continued after sunrise but I had to go back to sleep when the work day was ahead.

Morning wake-up call with a mobile phone. That lightning strike of the pictures was quite a shock. The first and second images are therefore the same jumble of consecutive frames.

I photographed the earth's shadow, which showed a peculiar coil in the atmosphere in two pictures taken at different times from the same place. apparently in the case of anti-twilight.

Antisolar rays

Jussi Säily, Ursa (Helsinki)

A strange light phenomenon caused by the midnight sun was visible in the evening from the pier of the cottage in Lapland, facing south. In the sky, a clear light line was visible first vertically. The border turned to the left at an angle of about 45 degrees in less than an hour, otherwise remaining in place. Could it be anti-twilight?

Good lord what a day here on the west coast. The Chase was already started at one o'clock in the day, when the first cells were activated while passing by Laitila. Then it continued well into the evening. Cells lit up and died, and that rumbling all day long in the background was a completely unconscious thing to hear. During the day, we also saw wonderful anvils and rain walls. Because they drive, with which the back pocket gives up, so our legion had to settle for the neighbor's barn again, thanks to the state and gas prices. The poor squat! Well, it turned out to be very close to ho...
