Hey guys, back from 2 weeks in the US visiting family in both Florida and Michigan. While there i was able to see some of the best convection and storms i've genuinely ever seen (photo dump incoming ) I decided to delete the previous post and put this in a new topic so I didnt clog up any actual discussions/feeds. July 20th featured an enhanced risk in Michigan, Due to bad positioning i was unable to get many pictures of the large MCS that developed producing 80 mph winds, QLCS tornadoes and quarter sized hail. However, I was able to get some shots of the storms anvils as they passed me to the North-West. Florida was much more fruitful in storm terms, delivering daily thunderstorms, heat indexes above 40°C and 23°C+ dewpoints SBCAPE was regularly in the 3000-4000 range with it reaching 5500 at one point, additionally it never went below 1000 j/kg during any of the days or nights i was there. While in South Florida near the town of Homestead I believe I was able to chase my first ever US Supercell, i'm still 50/50 if it was however radar presentation showed the storm deviating from the North West path of other storms and it began to move directly to the East. Additionally velocities showed the storm had some weak rotation in the mid levels. It was also the most electrically active storm i've ever experienced, multiple CGs in rapid succession with thunder becoming a constant, never ending low rumble in the background. I'm not sure if anyone experienced with supercell structure can help but it did have a substantial lowering on it for a good 30 mins with rising scud in the inflow region. No sign of anything tornadic but the storm did go severe warned for 30 mins. As the storm moved slowly off to the North East its Anvil was caught in one of the most amazing sunsets I've ever seen. I still can't believe i experienced this, just stunning. This happened everyday I was there as the sun set behind anvils of the daily thunderstorms. This was followed by around an hour of lightning as the storm slowly died and faded to the East, however tropical thunderstorms then rapidly developed off the south coast of the Florida Keys. With water temperatures between 31-38°C and Nightime temps never dipping below 34°C these storms were very electrically active. I will try to trim some videos of the light show and post some on here. The flight back home was pretty convective as well. Overall, an amazing trip that i'm already missing, will hopefully be able to go back soon. Hope you guys like the photos, not sure what to do about some of the weirdly cropped ones but oh well, I'll try to post some videos of those night storms if the jetlag hasn't killed me

Bad ain't it, this year? Woh Nelly

God morning-afternoon everyone. I have a question. Since cummulus are convective clouds, as long as there is convection, an ascending parcel of air will eventually saturate and form a cummulus cloud. But when will the ascension stop? is it there some way of estimating the maximum height of the cloud or is just the tropopause which stops it? Thank you very much for any anwser.

As requested by @Dami, a new thread for the new convective season. Reckon I'll be spending a bit of time in here

Been a good day for some of us! Carry on the discussion right here...

It's a shame about yesterday but we all may have another chance tonight and tomorrow. So here's another new thread for a new day. Good Luck everybody.

Wow!! look at the potential for this weekend and next week I really hope this comes off for us all. Please please let there be no downgrades lol. Anyway, please carry on here as you were.

A new thread here for the rest of Autumn. Autumn has been very good for storms this year! although sadly not everybody has had one yet. One rumble of thunder and one flash of lightning so far this year for me which I'm most grateful for . I am certainly not giving up any hope just yet as we all know storms can happen anytime of the year. Anyway good luck again all and don't forget to post up any pics and videos you have.

Never a good time to start a new thread, the old one was creaking a bit though! Please continue your convective storm chat, observations, opinions and forecasts here please! Old 'fred' here: http://forum.netweather.tv/topic/77030-convective-storm-risk-discussion-21st-june-2013-onwards

Another 2006? This March sure feels like it at the moment, bitterly cold with snow fall as you can see. http://youtu.be/wmLBR2UY0uE But 2006 was the last of the good, "hot" summers in recent years so I am hoping this is a good omen as it turned out to be then. Fingers crossed.

Here's a brand new thread for Autumn onwards and there's even a little potential for something tomorrow folks. . DISCUSSION British Isles, France A warm and moist maritime air mass is situated across the Atlantic west of the Bay of Biscay. This air mass is convectively mixed and is advected north-eastwards ahead of the approaching trough. Along the axis of warm air, a well-developed low-level trough is present and will move into France and the British Isles. At the surface, backing low-level winds are indicated by latest GFS model across southern France and the British Isles, leading to low-level convergence. A weak mid-level trough will also lead to some QG forcing. Daytime heating will result in weak instability across France. Instability over the British Isles is questionable, but elevated CAPE is likely given the well-mixed air mass. Given the lift along the trough axis and low-level convergence, at lead weak CAPE is likely. Together with CAPE and forcing, low-level vertical wind shear is expected to be around 10 m/s in the lowest km and low-level hodographs are rather large across the British Isles. Current thinking is that tornadoes can develop in this environment. Given the weak instability, chance of tornadoes seems to be too low for a level 1 forecast. Stronger storms may also produce excessive precipitation. Otherwise, severe storms are not expected across the Birtish Isles and France. http://www.estofex.org/
