Weak supercells possible tommorow across Serbia

Some marginal CAPE buildup on March 17th (up to 500 J/kg MUCAPE is forecast) in front of the cold front with the surface low somewhere above N-Austria. Potential for rotating storms exists in the central and eastern Serbia where SREH3 gets up to about 200 m2/s2. DLS is about 20 m/s. Main threat will be hail. CIN will be low so the storms will fire up fairly quickly. I usually wouldn't care for this type of setup, but in the early spring (late winter) every semi-severe convective weather is a welcome change.

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.







July 23rd 2010 - HP supercell near Portogruaro, Italy

Nice LVL2 outlook was ahead of us. Friend and I decided to chase in Italy, FVG region. The only region that made sense to chase. We got off the highway before Portogruaro for Varmo and Cordoiso. The outlook was bad, no initiation, was afraid that it will result in a bust. Nothing interesting was happening but then suddenly ... a storm! Crazy driving to get ahead of it to intercept but we were too late. Got some photos but the storm was too fast. It ran us over very quickly, especially with the bad roads. Wet microburst with winds over 100 km/h, fortunately no hail. This storm dropped a rain-wrapped tornado somewhere along the way so were kinda lucky. Once the wind was strong and with strong rain there is nothing you can do. Especially with people driving 20 km/h. Obviously there were not in a hurry to get out of there. Before the storm caught us we got a look at a nice wall cloud which was rotating nicely. The storm made quite a bit of damage, there was a lot of broken trees on the roads.











June 6th 2009 - Great day in FVG with supercells!

The forecast was good so me and two friends decided to chase in FVG (Friuli-Venezia-Giulia). Starting point was in Sežana then we proceeded to catch the first thing that came into our range. It was already spectacular on the radar when we started. We caught it close to city Udine.

On the road, still in Novo Mesto.




First supercell on a gas station near Udine. Nice inflow banding. Too bad there were stratus clouds all around us so we didn't get to see much other then the wall cloud and circulation.





Awesome view of the wall cloud.





Spectacular rotation. Too bad we were a little late so we head to do most of our shooting from the car.





Once again the awesome structure of the wall cloud. RFD is now obvious.





On a toll booth, in traffic ... RFD was really cutting into the wall cloud as seen here. Obvious lowering, it was trying to produce a tornado here but it couldn't.






This storm then hit the hills east of Udine. I'm certain that it would produce tornado if there weren't any hills on the way! Next supercell please ...

From the car.






Close to Palmanova. This supercell already dropped 2 tornadoes, one of them F3 with 10.5 km lenght and 250 m width ... Too bad we missed this one also.





Back north.




Interesting structure.




On the same gas station as before. Awesome view!




All over the sky. Nicely illuminated.








Panorama...




Successful stormchase, too bad we missed the tornadoes but that's how it is. Maybe with better CAPE ...

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!










July 22th 2008 - Summer storm

Funky looking storm, especially interesting is the short lived wall cloud, it looked like it bumped to a low-level moisture pool.
