Longwave upper trough overspreads NW Europe, with a number of shortwave troughs rotating around it within a belt of very strong upper winds, containing jet streaks of 180mph+. One shortwave trough and left exit of a jet streak combine to deepen a low over Biscay Tuesday/early Weds which contains the tropical airmass remnants of ex-TD Henri.

The Met Office has issued a Yellow Warning of Rain:

Valid to: 0900 on Thu 17 Sep 2015
Persistent and at times heavy rain is expected to spread from south to north during Wednesday, this affecting much of England and Wales. Some heavy and thundery showers could also develop across East Anglia and southeast England during the afternoon. Strong and gusty winds are also expected, with gales in exposure.
Rain should ease from the southwest later on Wednesday, but will persist across the north of the warning area into Thursday.
Some localised flooding is possible from fast responding water courses and standing water, this perhaps disrupting travel. Lightning associated with the afternoon showers across East Anglia and SE England will be an additional hazard.
