Convective/Thunderstorm Discussion: Autumn/Winter 2016-17

weisses

I was checking blitzordnung

Nothing shows up there ... Glad the lightning showed up on the pic you posted

Showing up on NW Storm radar app too.

Some serious hail starting here in West Clare, not particularly heavy but god they're like pebbles.

Update: Mini-Cell seems to have moved away, just rain now but a severe temperature drop with it.

Update 2: Massive sudden outbreak of hail.

Update 3: Rain. + Rate of 17.8mm/h

Potential for Lightning Sun night into Mon perhaps along the Atlantic coast

Yeah looks like a classic setup tomorrow for some stingingly cold hail showers

500mb temps between -25 and -30 given rise to decent lapse rates


Some instability and good DLS will produce some nice cloudscapes, Cb incus and most likely some mammatus about too.


DLS in the 65knot range - Squall line potential.


Trough crossing the so should be quite widespread activity.


Due to low CAPE values however, lightning activity will be low, confined to coastlines IMO.

ESTOFEX LVL 1 issued for tomorrow.

A level 1 was issued for W British Isles mainly for severe wind gusts.

SYNOPSIS and DISCUSSION

Ridge stretches from Azores through Iberian Peninsula up to France. Two long-wave troughs travel through Europe, one moves from CNTRL to E Europe and the second enters British Isles in the end of the forecast period. Southwardly moving cut-off is located over CNTRL Mediterranean. Another ridge covers E Mediterranean and Turkey. A shallow weak convection with a marginal lightning potential may develop within a mid-level wave over Belarus and Ukraine. Although boundary layer will be quite dry (2-3 g/kg MIXR) a very steep lapse rates (> 8 K/km) will provide 100-200 J/kg CAPE. Weak lightning activity is also possible with upcoming cold front affecting W British Isles around noon hours. Strong linear forcing of relatively moist boundary layer (MIXR ~ 6-7 g/kg) produces lobes of CAPE up to 100-200 J/kg and thus shallow-convection which combined with strong low-level flow (~ 25 m/s at 850 hPa) poses a threat of severe wind gusts along frontal boundary.

Recent sferics

Getting showers with hail mixed in now in Tralee

Oscar Bravo

Nice few recent strikes in North Mayo

A lot of mention on the Weather Forecast tonight for the potential of thunderstorms the next couple of days. Tomorrow mainly off the SW looks like could be active, maybe a few will stray onshore like today.

Meteorite58

Plenty of activity off the SW today, sferic off the Wexford coast 30 mins ago ( cloud moving away from land )

Recent lightning just north of Enniskillen
