The (possible record-breaking) Canarian #heat bubble (up to 35 °C!) will be sucked in by powerful Atlantic cyclones and carried as far as W-/C-Europe. By the middle of next week, temperatures of around 20 °C and locally around 25 °C are possible there too. #summerlike #weather #forecast #extreme

#Hurricane #Melissa from a #radar perspective. At first glance, the images may not be as stunning as the satellite images of the storm, but they impressively show how Melissa developed into an almost perfect storm with an almost perfect eye wall.

Hurricane Melissa has just broken the record for the driest eye ever observed in a tropical cyclone, with a temperature of -4.75°C.
This is nothing short of astronomical.

The #severe #storm for parts of Western and Central #Europe has been named by @meteofrance.com: #Benjamin. It temporarily has the characteristics of a Shapiro-Keyser-Cyclone. The @dwdderwetterdienst.bsky.social forecast takes this into account with a frontal fracture.

Further (extreme) heavy rainfall and floods for parts of #Spain due to #DANA (=Depresión Aislada en Niveles Altos) #Alice. After #Tarragona was affected yesterday, this time it is the region south of #Valencia and #Amposta. The satellite image shows a two huge, stationary storm systems.

Potentially dangerous hybrid storm for the Southeast/East US starting this weekend? Frontal zone/trough could interact constructively with (sub-)tropical disturbance. Also interaction with future Tropical Storm Jerry? (->steering/moisture transport!). But very uncertain due to its complexity!

During the week an omega blocking pattern will build up. It sets up quite far to the west, so that the large-scale circulation “ATR” (Altantic Ridge) is favored. This will bring calm weather to large parts of W/C-Europe and unsettled weather with heavy precipitation to the southeast and east.

Updated #tornado statistics and illustrations from #Germany from our colleague @meteomabe.bsky.social.
Your probably all know the #tornado stripes for Germany that I have posted several times. Starting at 2000 since with a robust dataset from then on. It shows a clear maxium for the years surounding the recors year 2006. #showyourstripes 1/3

Something to monitor for the Caribbean: Invest #I95L has a high probability of cyclone formation within the next 48 hours. The models suggest that the system could become a #hurricane as it nears the Lesser Antilles in the next 3-4 days. #tropicalweather

Silly Jimmy Kimmel. He should have just called for all homeless people to be killed and he’d still have a job.

Maxima partly above 30 degree, potential for severe weather. That is sth that doesn't necessarily sound like beginning of the third decade of September. Maps look more like midsummer autumn.

Wonderful example of a line oft storms within which several spin-ups (rapidly forming embedded mesocyclones) occur. This just happened in eastern Germany. The risk of tornadoes was increased.

Extremely heavy rain in western Germany. North of the Eifel, in the greater Mönchengladbach area, 100-130 l/m² dropped in 6 hours. The highest warning level of the weather service is in force, and there is also a local threat of major flooding. #severeweather #floods

The national weather services are now taking action in response to the threat and have raised their warnings to the second-highest level (France, Luxembourg, Germany). #severeweather #floods #heavyrain

A very humid air with an elevated mixed layer (EML), combined with strong synoptic forcing, leads to a hybrid (partly stratiform, partly convective) heavy rainfall event in NE France, W Germany and BeNeLux during the night of Tuesday and Tuesday morning. #SevereWeather #Floods

There are increasing signs that a pot. severe convective situation could develop in Western Europe today. Supercells could develop in moderately unstable but extremely sheared subtropical air with increased #tornado risk in places. The focus appears to be on NE France, Belgium and the Netherlands.

"Der Sommer war ja ziemlich wechselhaft und kühl" - so oder so ähnlich hört man es häufig. Wechselhaft: Ja! Aber kühl?!
Vor dem Jahr 2000 hätte ein Sommer wie 2025 zu den heißesten überhaupt gehört! Ein Extremereignis, dass erst durch die Klimaerwärmung der letzten 25 Jahre quasi normalisiert wurde.

Tomorrow evening there is a slightly enhanced risk of a #tornado or two over Benelux and north-eastern France! Very prominent low-level shear and veering overlapping with weak/moderate instability. Strong forcing is possible just ahead of the approaching cold front. Sounding: @kachelmannwetter.com
