Thunderstorms in Slovenia

Thunderstorms dominated the weather across Slovenia today, but there was no real severe weather threat. Some thunderstorms did produce small hail. Rather surprisingly considering non-existent wind shear and relatively small instability of a couple of hundred J/kg. Dewpoints never reached more that 13-14 °C.

August 5th 2010 - Possible supercell near Novo Mesto

Got run over at home with a nice cell in the line. I liked the moist east wind on the ground before the storm. Veering was pretty good in combination with the jet from the south. A nice wall cloud. Could not really tell if the thing was rotating because it was too far away. Pretty dynamic. Higher CAPE would definitely help.

August 3rd 2010 - HP supercell in Slovenia

I had to core punch this supercell but I never got a good look at it. It was really rain-wrapped. A high precipitation supercell with bad structure.

June 17th 2010 - High end LVL1 event in Slovenia

Wasn't expecting much from this day but it went really well. My first sight of the supercell was near Trebnje. It took awile to get on the highway ... Missed the first supercell but bagged the next one, crazy driving saved me! :) These storms dropped large hail near Grosuplje and made a lot of damage.

From Trebnje.

Still very unorganized but very active. I was right under all the action. Crazy lift and inflow. A lot of CGs also, was kinda scared to stand outside of the car! Was dropping hail already.

Crazy inflow. Mesocyclone occlusion began here already with rain on the levt. I was moving practially all the time. It was fast.

A few kilometers ahead. Nice wall cloud. RFD really close, wall cloud already a bit in the rain. Not showing the structure very well.

On the road back along Trebnje. RFD on the left, not looking very good.

I still got one more look on the meso once I got ahead of the storm. Really crappy roads here, impossible to track anything here for long period of time.

On the road back at Krško.

May 25th 2009 - Monster Ljubljana supercell

This was a supercell that really surprised us all. I didn't even went to chase, kinda got caught unprepared but I took some photos from my home in Novo mesto. This supercell dropped 6-7 cm hail in Ljubljana. I wanted to intercept it in Novo mesto but it kinda dryed out, so no specatular photos for me. My friend got a couple of fantastic photos of the mesocyclone in LJ. Check them HERE. Inflow easily seen more than 70 km far away.

It was more than 2000 J/kg CAPE that day with 20 m/s DLS but no low lever winds thus no veering and helicity so I did not expect such a supercell forming!
