The UK will be between an upper trough over the far N Atlantic and upper level ridge over central/eastern Europe on Monday. A slack anticyclonic flow will be present at the surface, while the upper flow will be cyclonic SWly. Greatest instability today will be towards eastern Britain, where dew points approaching the mid-teens and temperatures reaching the low 20s C across eastern England and SE Scotland will generate 300-500 j/kg CAPE during peak in sunny spells this afternoon. Sea breeze convergence will develop inland along these eastern areas through the day too, which combined with the instability building and weak lift from cyclonic flow aloft, will support the development of scattered heavy showers and isolated thunderstorms. A few funnel clouds or even a brief/weak tornado are possible along breeze convergence zone.
