Good ongoing live stream here that is keeping a watch on those big storms breaking out across the southern US states at the moment:

I saw that there was a "rare" warning issued. Could be bad.

Stunning.

It's almost as if all the energy in the cloud is just feeling its way of how to touch the ground.
Beautiful, but terrifying.

I know I am being very OT, but I love this compilation of tornado sightings.

It doesn't focus on the destruction that these things can bring, but the sheer beauty of the tornado is undeniable.
Such variety in its shape and structure.
Beautiful.



thank you to all those storm chasers who risk their lives just to capture the beauty and power of nature.

Beautiful but deadly. This footage, captured in April 2015 in Illinois, is the most frightening yet awe inspiring I have ever seen of a tornado. Sadly, the wife of man who took this video died due to it.

Interested in seeing how much thunderstorm activity might happen tomorrow. Plenty of convection with a few hundred J/kg available at times and good lapse rates especially from the early afternoon to the late afternoon. Low level shear available, peak DLS early and later so missing out a bit in the afternoon during peak diurnal heating but still some available. Hard to pinpoint activity ,anywhere could see a few sparks but the afternoon looks the best chance moving from W to E across the country. Convection could produce big squally showers of rain and hail giving locally strong gusts of wind. Might see a few reports of large hail tomorrow. Showers wintry in nature especially higher ground and some interest in snow accumulations in the W, NW especially towards evening.

Cold air advecting out of Greenland / Canada behind the cold fronts that are making their way over the country now. Might see a few sferics show up along the Atlantic coastal counties by early morning.

Nice NASA EOSDIS sat pic of the cold airmass from earlier today.

Look at the frigid eastern Canadian landmass less than 1900 miles away. Such a contrast.

Looks like some activity around Carna (Galway)

Day 1 Convective Outlook
VALID 06:00 UTC Fri 26 Mar 2021 - 05:59 UTC Sat 27 Mar 2021

ISSUED 07:32 UTC Fri 26 Mar 2021

ISSUED BY: Dan

An upper trough will migrate eastwards across the British Isles during Friday and Friday night, the associated cold pool creating an environment with steep mid-level lapse rates and yielding 300-500 J/kg CAPE in response to SSTs and diurnal heating inland. A cold front and associated band of rain will track eastwards across Britain during daylight hours, clearing to the North Sea around 16z. Forcing and the strongly-sheared environment will allow embedded line convection to occur capable of producing hail and squally winds in portions of the front, and this may intensify somewhat as the front approaches the E Midlands / E Anglia / SE England during the afternoon hours given some modest surface heating prior to its arrival. An isolated tornado cannot be ruled out where breaks develop in any bowing segments.

Scattered showers will follow the cold front, especially numerous across Ireland during Friday afternoon as an occlusion swings through, this then tracking eastwards into western Britain during the evening hours. Showers will tend to become more isolated with time during the early hours of Saturday as ridging builds from the west, mainly confined to NW England and SW / W / NW Scotland by the end of the night. Some sporadic lightning could occur from any shower, hence the broad LOW threat level issued, with gusty winds and hail likely in many of the showers (and snow even on modest hills).

Shear weakens within the trough axis, but some notable backing of low-level winds is expected from Munster, N Leinster to Ulster during Friday daytime, and this could be the focus for some better organisation of cells with perhaps some slightly larger hail and an isolated tornado. Shear will increase across SW Ireland later in the afternoon as the trough axis shifts eastwards, although by this stage the depth of convection may be slightly shallower. A low-end SLGT has been introduced for some sporadic lightning, but confidence is rather low in this aspect due to a messy mixture of dynamic and convective modes. The focus for some sporadic lightning may shift to the Bristol Channel and adjacent parts of S Wales / SW England for a few hours during the evening period, along with W Scotland.
