June 2024 was almost 1.4 K warmer than 1961-1990, only 0.4 K warmer than 1991-2020, but a very cool first month of the summer compared to 2021-2050. #climatechange

An exceptionally warm June night, especially in the E and SE Germany. A new all-time record was set in Dresden-Hosterwitz with a minimum of 23.8°C (previously: 22.8°C, measurements since 1949), in Regensburg a monthly record was set with 21.4°C (previously: 21.3, since 1879).

Locally a lot of rain has already accumulated close to the Alps (here radar precip sum), measured 122 mm in Kruen. And a lot of rain is about come with enhanced local #flashflood risk! Map shows 06 z run of ID2. Last map shows the spread for each gridpoint ID2 EPS #severeweather

A lot of rain expected for parts of W and C Europe during the upcoming week (RR240h, ECMWF, run: 14.06. 00 UTC).

I am still flashed when looking on this radar precipitation sum. Such high amounts of precipitation over such a big area. Still incredible to see! #hochwasser

In the meantime models are in a good agreement about the upcoming intense rain event (e.g. compare ICON and ECMWF EPS probabilities). That will probably have some major impact having in mind the large area of heavy rain! #Hochwasser #inondations

Excessive precipitation expected for parts of S and E Germany especially for the end of this week and the upcoming weekend. Although model differences for exact placing and intensity exists, EFI from ECMWF already shows a strong signal for days 3-7. Basis: run 28.05. 00 UTC.

Development of the general weather situation until Thursday, with a developing low pressure zone over Germany in the coming hours. This is triggered by the UL flow and moving slowly N(W)ward, bringing excessive precipitation to some areas from SE Germany into W Germany . #Lisa

Still increased uncertainty for the upcoming possible excessive precipitation event in parts of central Europe (including SW Germany (Tuesday/Wednesday). Exact development of the surface low still uncertain

Interesting setup: N of the Alps some #supercells and later on a developing MCS. Large hail and severe winds and enhanced risk of tornadoes in parts of Ukraine and Belarus. Severe weather expected for parts of Middle East. Whatsmore: Few #severe storms E Spain and a landspout risk for NW France.

Excessive precipitation expected tomorrow for part of Germany. It starts in the afternoon hours an will persist during the night. For the E Rhein-Main area (my place) the ID2 EPS 18 z median has even 30 l/qm in 6 h and a probability of 45% for >60 l/qm.

That looks really bad for fruit and strawberry growers in many parts of Germany and the neighboring countries where trees are in full blossom or small fruits have already built (e.g. my peaches). #Aprilwinter #frost

Everybody is looking for the cold front of #Yupadee. However, LL wind profiles in E Germany / W Poland in the warm sector also look quite interesting with low topped convection forecasted in that area late afternoon / evening. #renata

Likelyhood of a significant passage of the cold front on Monday is increasing. ICON-D2 EPS 00 UTC shows several members with >Bft10 gusts. Worth monitoring keeping in mind leafy trees. #Yupadee

Here is the final "Grünlandtemperatursumme" up to the end of March. Only 1994 was a bit higher. Frankfurt cracked the 500 mark on April 1st this year. In the meantime we have already reached >650K.

Yes, it has been very wet in England over the past 18 months. The wettest on record (since 1836).

March and February 2024, both in the TOP10 of warmest March months since records started? Looks reasonable when using the forecasts for the next two weeks. Also extended outlooks of ECMWF point to this. Not excluded that March may even reach a new all time record.

2023 was another year below average concerning the number of #tornados in Germany. Only 33 tornados were confirmed, so far. 13 of those were waterspouts. Here are the current #tornado stripes showing the development of tornadoes in Germany of the last 25 years. #showyourstripes

Current status of vegetation. Many weather stations have in the meantime passed the 200 K threshold of the so called "Grünlandtemperatursumme" (which is a measure for start of vegetation). Many (here Frankfurt/Main) are on record path.

There are many stations in Germany with a new minimum record of #frost days and most days with maximum of ≥10°C. One of many examples: Geisenheim, no frost days so far and only two days with maximum ≤10°C. #Frühlingsfebruar

Is this really #winter? Frankfurt examplarily: Only days around mid Jan were below average. Current mean (last 3 weeks) comparable with mean of mid March. Next days will be even warmer. Frankfurt: Already 3 new daily records for Mean, 3 for Min and 5 for Max! #Februarfrühling

That will be an interesting (#severe) weather situation on coming Wednesday. Heavy #snowfall and black ice are both possible. This is ECWMF 12 UTC. Exact postion unclear but somewhere over the middle of Germany.
