We have a battle this week. Between cold air from the continent and warmer (yet more unsettled) air from the Atlantic.
For the rest of the week the cold air wins - a significant windchill for Thursday and Friday.
As we head into the weekend it looks like low pressure takes charge from the southwest - wet, windy and wintry for some as we head into Saturday.
After a cloudy start for many with perhaps the odd spot of rain, some sunny spells will develop through. Largely dry afternoon, but cooler as southeasterly breeze begins to develop. Highs 8°C.
Cloudier with risk of patchy rain and drizzle for the Isle of Man. Otherwise, dry for many places with some sunshine. Breezy with strong winds over the Irish Sea gradually moderating.
Feeling cold with a marked wind chill. Overnight frost possible in shelter from the wind.
Probably a similar day to Thursday but with lighter winds. Cloudier in the west but most areas seeing some sunny breaks. Cold with a widespread and possibly sharp overnight frost.
Timing is uncertain at this stage and the detail will become clearer as we head nearer the event. A spell of wet and windy weather will move eastwards during the early part of Saturday. This is likely to turn to snow over higher ground and possibly (briefly) to lower levels for a time.
Showery and windy conditions follow for the rest of Saturday, turning milder from the west but with further rain later.
