DISCUSSION: Within the past 24 to 36 hours, yet another impressive round of strong to severe thunderstorms erupted over parts of western to northwestern Germany. As has consistently been the case in recent days and weeks, the skies once again did not fail to disappoint people who were in the path of some of the particularly stronger convective storms. With strong convective instability in place both prior to and at the time of convective initiation, this greatly boosted the potential for strong to severe thunderstorm activity to be generated across several parts of Germany. As you can see in the image and raw footage attached above, one of the stronger storms exhibited fairly impressive misoscale to mesoscale features such as effective low-level lifting of developing clouds which helping to generate the shelf-like cloud feature racing out ahead of the approaching thunderstorm. This type of shelf-like cloud feature is very characteristic of strong to severe thunderstorms since features acts to often lift and destabilize air parcels out ahead of the storm which act to keep a given storm revitalized throughout the course of its lifetime.

DISCUSSION: Within the last 24 hours, there has been a fairly impressive increase in the coverage of deeper convection across parts of western and northwestern Europe. During the last 24 hours, a weak (but slightly invigorated) piece of mid-level energy was propagating across western Europe. As it did so, the surface low pressure helped to shift the larger-scale regional wind field direction from a northeasterly to more of a southeasterly orientation. Hence, this wind direction change helped to increase the influx (i.e., the amount of incoming air from a given region) of warmer air from the greater Mediterranean Sea. As this warm air coming north increased with time, this helped to bolster the overall amount of convective instability as a result of the warmer air closer to the surface being coupled with much cooler air aloft.
This increasing unstable lower-to-upper atmospheric combination led to a regional atmospheric environment which was much more conducive for deep convective development. As shown in the footage above, one such convective storm developed into a severe thunderstorm which exhibited a classic shelf cloud. Shelf clouds often form in convective situations wherein there was effective low-level lift which helped to create the layered cloud deck which was observed as a shelf cloud out ahead of the aforementioned severe thunderstorm.

DISCUSSION: Within the last 12 to 24 hours, yet another impressive round of strong to severe thunderstorms impacted portions of northern Europe. As these strong storms impacted countries including (but certainly not limited to) Poland, there were several instances of tremendous scenic storm exhibitions for people who were positioned in or in the vicinity of the path of some of these storms. As captured in the images above (courtesy of Meteo Europe Facebook team), you can see how there was incredibly effective lifting on display out in front of this particular shelf cloud which gradually propagated across the landscape of central to eastern Poland. Note how just behind the most pronounced part of the incoming shelf cloud, you can also see how there is a seemingly small amount of deep-layer clearing which allows a person to see directly though the approaching storm. In addition, this clearing often gives the regional sky a somewhat bluish-green appearance which is always an awe-inspiring sight. It is always neat to see the natural power of Mother Nature at work!

DISCUSSION: As a strengthening mid-level low-pressure system gradually moved across portions of northern Europe, the stage was quickly set as of earlier today for relatively strong thunderstorm activity. This set-up was largely due in part to the fact that the incoming low-pressure system helped to amplify the strength of southerly flow across this part of Europe (i.e., thereby bringing in critical warm, moist air into the region during the 24 to 36 hours leading up to this particular convective event). Due to the convective instability in place prior to the onset of the deeper convection, this allowed for very intense updrafts to form during the height of the most intense thunderstorms. As shown in the graphic above, these intense updrafts facilitated the generation of relative large hailstones in association with the blow-up of the deeper convective cluster shown in the satellite image attached above courtesy of the EUMETSAT satellite feed. In addition, note the particularly impressive lightning associated with the deeper convection which further indicated the natural ferocity associated with these deeper convective storms. In strong convective storm threats such as this one, it is important to note that safety should always be put first and foremost by being weather-ready whenever there is a threat for any type of severe weather.

DISCUSSION: Just over four days ago, a major hailstorm impacts areas both in and around Istanbul, Turkey. Prior to the onset of this major hailstorm, there was a particularly impressive regional cloud exhibition on display as strong rising motion was evident in the raw footage attached above. In addition, right at the very beginning of the footage attached above, you can see the rising motion in action by way of the rapidly rising cloud columns towards the back-right portion of the image. This is a clear sign of what was a fairly strong core updraft. There is no debate that this was a particularly intense storm based on the many sources of large hail reports which were submitted and observed in other footage closer to the ground during the course of this recent severe weather event that slammed south-central Europe. This event reinforces the point for why it is incredibly important to always remain weather-ready during any period of time in which there is a threat for severe weather!
