    Storms and Convective discussion - September 2023

    in Storms & Severe Weather

    I'm surprised nobody has mentioned ESTOFEX as they have issued a level1 threat of severe wind gusts and Tornado threat across Ireland, Northern England and Scotland for this evening/overnight.

    DISCUSSION

    ... Ireland to N England and S Scotland ...

    A sharp short-wave trough is forecast to cross the area in the evening to night hours. Strong synoptic-scale lift and drop in the 500 hPa temperature will result in a pocket of steeper mid-tropospheric lapse rates and marginal CAPE. At first, CAPE will be elevated with some embedded showers or weak thunderstorms embedded in the main stratiform rain shield. At and behind the cold front, strongly forced linear segments may form with surface-based CAPE. Strongly sheared environment with 0-1 km bulk shear reaching 15 m/s will yield isolated severe wind gust and tornado threat.

    “1083.8mb

    The highest barometric pressure ever recorded was 1083.8mb (32 in) at Agata, Siberia, Russia (alt. 262m or 862ft) on 31 December 1968. This pressure corresponds to being at an altitude of nearly 600 m (2,000 ft) below sea level!”

    This has probably been broken last year with a recorded pressure at Tsetsen-Uul, Mongolia at 1094.3 mb.

    I think 10cm for us tomorrow during the day then during sleety later on and turning to wet slush thursday. Weekend and beyond looks interesting too though. Let's all post pictures if we get white stuff. Sorry "coasters" it must be frustrating.

    With 850' Temps at -8℃ and greater they'll be no marginality here on the coast, had a small flurry this morning and 850's were hovering around -6℃ and winds coming off the sea.

    It would be interesting to see the constellaton now, when this anticylonic gloom shifts, it is normally the 11th brightest star in the night sky but it has dipped out of the top 25 at the moment. Orion would look a little odd.

    The skies were clear here on the east side last night and Betelgeuse could be clearly seen but has dimmed, so much so that his 'belt' is now brighter than his left shoulder..
