Low centre analysed at 06 UTC 31 August 1001 hPa Northern Ireland forecast to deepen 986 hPa by 00 UTC 1 September (UKMO).
Morning visible satellite imagery highlights the conveyor belt structure with a small cloud head west of Scotland. In radar imagery multiple cloud front structure is weakening. During early morning hours some sharper line convection was apparent. Isentropic mass ascent and orographic effects conributing to ongoing rainfall over Scotland.
Blended WV and IR imagery shows the large scale trough west of the UK, the cloud head and a filamentary dry intrusion spearing into southern Scotland.
300 hPa wind field shows the low is deepening, rather classically, in the left exit/right entrance region of two jet streaks.

A very brief heavy burst went through Penzance associated with the segmented line convection. Only 1.8mm between 07:30 & 09:00, but most fell in 5 minutes around 08:45.
NW wind picking up now. Surf, which is currently smaller & less powerful than yesterday, getting blown out and forecast to decrease steadily now the lows in the wrong place.

Similar in Shropshire, with 1.0 mm falling in 6 minutes (max rainfall rate of 16 mm/hr at 1037z), just ahead of the front which went through at 1045z.

Absolutely nothing here in SW Devon.
Just a few drops.
Zero in my 5 inch gauge.
Forecast somewhat wrong for this location from UKMO.
