Exceptionally deep cyclone Ana/Yves hits W France this morning – winds over 160 km/h reported!

Severe Weather Europe - 11. Detsember 2017 - 9:48
Exceptional view of the very deep cyclone Ana/Yves currently over NW France! Central mean sea level pressure has dropped all the way to 965 mbar, a very deep system for so far south! Slender wisps of clouds wrapping around the core of the system suggest evaporational cooling in the area and sinking of air, enhancing maximum winds. Peak winds of 161 km/h have been reported in western Pays de la loire and Pointou-Charentes (station Ile de Ré – Saint-Clément-des-Baleines (17))! Exceptional satellite view of the deep cyclone over W France this morning! Note the wispy cloud structure wrapping around the southern part of the core, suggesting evaporational cooling in the area and sinking of air, enhancing maximum winds. Image: EUMETSAT.

Extremely strong southwesterlies and Foehn effect across the Alps on Monday

Severe Weather Europe - 10. Detsember 2017 - 21:26
The series of successive deep lows over central Europe today and through Tuesday will result in a very steep pressure gradient between central Europe and the Mediterranean. It will result in unusually strong southwesterly winds and strong warm air advection from the Mediterranean into the Alps. Additionally, strong Foehn effect will further raise the air temperature along the northern Alpine flanks. ICON-EU model guidance for peak wind gusts at 850 mbar level (1500 m) across the Alpine region on Monday. Map: Wxcharts.eu Intense southwesterlies are likely to gust well above 150 km/h across higher elevations of in central and eastern Alps, with many locations likely approaching 200 km/h, possibly even exceeding it.

Major snowfall in Ireland and parts of UK on Sunday

Severe Weather Europe - 9. Detsember 2017 - 22:30
Rapid deep cyclogenesis will take place during the night and tomorrow over Ireland and the British Isles. Cold mid levels will combine with strong advection of humid low-level airmass, resulting in significant snowfall across parts of Ireland and the UK. Various models are in very good agreement for snowfall across Ireland as well as Wales and central England. GFS model, map by www.wxcharts.eu Up to 10-15 cm of snowfall seems likely for parts of central Ireland. Wales will see up to 15-25 cm of snow, locally possibly more. Central England will likely see up to 10 cm snow. Depending on the track of the low, some snow may fall also in southern England, as far south as Somerse, Wilthire, northern

Very deep trough over western Europe, significant warming into central Europe and Balkan peninsula on Monday

Severe Weather Europe - 8. Detsember 2017 - 18:31
An extremely dynamic pattern is evolving over Europe this weekend as a very deep upper trough / low has established over northern Europe. Further development of the pattern suggests an additional deepening of the trough while it spreads towards western and central Europe. Its core will be exceptionally deep as can be seen on the map below, meanwhile a strengthening upper ridge will evolve across SE Europe and the Balkan peninsula. In between, a sharp pressure and temperature gradient will result in a very powerful jet stream with strong warm air advection from the Mediterranean region well north into central Europe and towards the eastern Europe. Keep in mind that this sharp flip comes just a day after the very

A good amount of snow for United Kingdom until Monday, Dec 11th

Severe Weather Europe - 8. Detsember 2017 - 18:11
An interesting weather pattern is shaping up for the western Europe where a very deep trough currently sitting over N Europe will be spreading south towards central Europe and another trough will be pushed across far N Atlantic towards the western Europe. As a result of merging troughs, a large and deep cyclone will form over the British Isles on Sunday and gradually move towards Benelux on Monday. Conditions will be favorable for quite some good amounts of snow also over parts of UK, Ireland and Scotland as mid-levels will be significantly cooler than lately and indeed well below zero degrees Celsius, while the humid airmass associated with deepening cyclone will be entering from the SW. This will result in

Significant frontal system with lots of snow over Alpine region this weekend

Severe Weather Europe - 8. Detsember 2017 - 17:22
Central Europe and Alpine region are in for another deep trough and significant cold blast passage this weekend as a sharp cold front is expected to cross the region tonight, bringing a lot of fresh by tomorrow afternoon snow especially for parts of Slovenia and Croatia. The deep trough is a result of blocked N Atlantic and so meridional flow has established across Europe, meaning colder weather and deep troughs from the Arctic region towards the Mediterranean and Balkan peninsula. This same trough which is digging towards south today, has resulted in apowerful windstorm over Scotland and Faroe Islands yesterday and dumped a lot of snow and rain over the WSW Scandinavia. 500 mb heights anomaly on tonight, Saturday Dec
