Deep Atlantic low fuels disruptive midweek rain and wind A deep Atlantic low to the northwest drives successive fronts, sending further heavy rain across the UK. Wednesday brings the worst to Wales and southwest England under Met Office yellow warnings, with additional bands reaching Northern Ireland and southern and central Scotland while eastern England stays patchier. Much of northern Scotland sees sunny spells between showers clipping the far northwest, as winds strengthen notably along western coasts. The blustery setup keeps temperatures a touch above seasonal norms despite the unpleasant conditions. Overnight, the rain pushes into East Anglia and the southeast before clearing by morning, leaving showers in the northwest and many areas briefly drier to start Thursday, with temperatures dipping into single figures yet remaining significantly above average for a December night.
Another surge on Thursday, brief Friday respite, then a stalling system into the weekend Thursday starts largely grey with some sun in central and eastern Scotland before the next rain band surges in from the southwest onto already saturated ground. Heavy rain hits Wales, southwest and southern England with Met Office yellow warnings, spreading across most of England and Wales and pulsing into Scotland and Northern Ireland as winds strengthen, potentially very blustery in the southwest. Conditions stay mild but hazardous with spray and surface water through the evening rush hour, then rain gradually pulls away. Friday turns brighter and breezier for many as fronts retreat, but the next system arrives and stalls into the weekend, focusing more rain on western areas that need it least. Weather patterns begin to shift heading toward Christmas week.
