A drone photo of Saturday's thunderstorm rainwall

3.7. One of the Skywarden phenomenon categories is rainwall. Judging by the photos taken by Timo Alanko, these come into their own best when a drone is used. The shown rainwall in Vaasa was from latest thunderstorm on 2 July. As Markku Siljama states in the comment on Alanko's observation, drone photos show the proportions of things.

Wednesday storm on the west coast

1.7. On Wednesday, a handful of spotters were greeting the thunderstorms that rose over the west coast area. The high price of gasoline forced Pirjo Koski and Riku Poskiparta to station themselves in the neighbor's barn in Laitila, but as you can see from the picture, the decision was not bad. "It must be said that it was a quite an incredible day here in the southwest, so far thunders has circled Laitila from far away," the observers write.

Good crepuscular rays Friday night

26.6. A surprisingly large number of observations of twilight rays was reported to Skywarden on the Friday night. The slightly less frequently reported component of the phenomenon opposite the sun is called the anticrepuscular rays. Mikko Luoto got a great picture of them on Friday at 23:40 pm from a ski resort tower in Vaasa.

A notch better case of reflected cloud rays

21.6. On the night between Monday and Tuesday, Kuusamo's summer night painted the underside of the cloud deck with splendid reflected cloud rays, that rank easily among the top examples of the phenomon in Taivaanvahti. The photo was taken by Jani Päiväniemi in Juuma. Cloud rays are alternations of light and shadow, the rarer reflected type arising from light whose immediate source is reflection from water surface.

I followed the thunderstorm situation all day and finally four of them started happening in Lappeenranta as well. I had chosen the Luukkaansalmi bridge as the anchorage point and it turned out (once again) to be the right place. The catch was one flash photo and a couple of nice avalanches. And finally the rainbow.

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. EDIT added as an illustration the body fr...

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 :(

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.

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?
