#StormAmy probably being named very soon as models are in better agreement this morning. It could be a record-breaker in terms of low pressure for the time of year as well.
W + N Scotland in particular is likely to see some intense winds with this one.

While the Azores have seen some tropical storms and a few hurricanes in the past, #Gabrielle will be at the upper end of the climatological range in terms of intensity. People on the central islands in particular should take this storm seriously and prepare for it

This one will happen very close to home...heavy (locally thundery) rain in far W Germany and surrounding areas. A few locations could see up to 100 mm in under 24 hours, enough to cause some flooding issues despite rather dry antecedent conditions. #weather

It will feel like a tropical storm for people living / holidaying on the W Danish coasts or in far N Germany in terms of rain and wind (only with lower temperatures and no, it is NOT a tropical system). High-res models indicate very heavy rain through late WED and local gusts between 80 and 100km/h

A quite remarkable rainfall event is unfolding in south and east Denmark. Some stations have seen over 100mm in the past 24 hours, with Neble in the far SE recording 136.7mm so far.
The Danish all-time 24h record is 168.9mm recorded in July 1931.
There are increasing reports of flooding.

Busy days at the ESSL Expert Testbed in Wiener Neustadt. We discussed the previous day’s extensive severe weather in France, followed by an in-depth look at the risk across Austria and surrounding areas today. @essl-ecss.bsky.social

Severe risk later today and into Saturday across parts of W Europe as moderately strong SW upper flow overlaps with areas of seasonally high instability.
Parts of France, SE England & Belgium are likely to see severe storms through early Saturday, with large hail and damaging winds in places

A high-level view of the Kit Carson supercell (complete with base and mammatus) in eastern Colorado late Friday as seen from the plane during the climb-out from Denver Airport. It was producing hail up to baseball size around that time. #cowx #stormhour

Some impressions from Sunday’s severe storms in NW #Oklahoma. While we didn’t quite make it to the very photogenic Arnett tornado in time (waited too long for the stratus to finally retreat N near Alva) we did capture amazing supercell structure that day. #stormhour @weatherandradar.bsky.social

And an equally impressive environment by central European standards (e.g. ERA5 profile S of Rostock that afternoon). One of those occasions where spring/early summer dynamics meet moderately unstable air masses and create high-end tornadic setups.
