Disrupting upper trough will continue dig across mainland Europe, forming a cut-off upper low. The net result is the more mobile northwesterly flow begins to slow/stall, with limited eastward progress by Tuesday night.
With a cold front having cleared through during the early hours of Tuesday, the post-frontal environment is characterised by cold air advecting across relatively warm seas. This will generate a few hundred J/kg CAPE, with numerous wintry showers developing over open seas and then pushed well-inland by both strong northwesterly steering flow and also embedded troughs in the flow aiding greater organisation. A few lightning strikes, gusty winds and small hail (amongst pre-existing rain, sleet and snow) will be possible.
