Addition to Mari's weather entry
Here you can see registered lightning strikes from the
past 48 hours. Those over Germany are all from today (25 Feb 2022), as cold-ish air pulled down
in a very broad stream, over the open (moist) North Sea into Northwest Germany. There, with relatively mild temperatures at around 5-7°C, and with help of the higher sun, it created ideal conditions to for afternoon thunderstorms. (The temperature between upper and lower atmosphere must be around 40°K or larger in order for thunderstorms to appear) In Germany thunderstorms aren't that unusual this time of the year with the right conditions (e.g. cold winds form NW, and "relative mild" ground temperatures and the sun already getting stronger).
What comes to my mind is however, that the weather situation over Europe reminds me more like springtime (end of March), and not the end of February...
Stockholm, Sweden
25 Feb 2022
Even up here in Stockholm, everything reminds me of the weather you would normally get
in the end of March, or first week of April. The shifts between snowy winter landscape and mild thawing weather are now even more rapid than I mentioned in my earlier entries.
After the storm a couple days ago, we got winter conditions, extremely icy roads just everywhere (due to the previously mild temperatures and rain as the core of the storm passed over Stockholm) - quickly froze over just hour afterwards in gusty winds form the north, turning streets into ice skating surfaces. (not fun!) Then all of the sudden, mild again. Early this morning however, and to me totally unexpected - everything switched to winter again, with 4 cm snow (see pictures)
And now, early evening ? Most snow is gone. +3°C (37.4°F) The maximum today reached 4.7°C (39.2°F)
So yeah, this whole weather pattern feels very much like end of March / beginning of April (back and forth weather, between winter and spring).
Thunderstorms however, really don't show up this time of the year. (maybe once per 15-20 years) For T-storms to form over Stockholm you need a sun that stands higher.... like she does in April (or like now over Germany), in order to experience an occasional bang (usually like an afternoon, inland shower towering, giving off a few thunders).
