In my last update I mentioned that Halloween was looking unsettled and unfortunately that’s still very much the case. Low Pressure just to the North of Scotland will bring a couple of bands of rain across the country through Wednesday and into Wednesday evening. If you’re looking to go trick or treating then I think the best place to be is across Scotland though even here I think we’ll see some rain moving into Western parts, perhaps more showery though.

Elsewhere, as you can see on the rainfall charts below its going to be quite wet with spells of moderate and at times heavy rainfall, it’s going to be quite windy too across Northern Scotland and any exposed Western facing areas.

Whilst the above details are likely to change slightly, the chances of spells of rain and wind on Halloween are now high. If we move through onto Friday now the models are beginning to hint at the possibility of a secondary low forming. This brings the potential for some very strong winds and heavy rain, at the moment the worst effected areas are forecasted to be across Southern and Central England although the precise details are likely to change as the models firm up on this.

Summary:

Through the course of this week it’ll turn increasingly unsettled as High Pressure in the Atlantic moves West allowing Low Pressure to establish itself across the UK. Wet and windy weather is expected for some if not most areas on Halloween and into the Halloween night. The potential on Friday is then for a secondary area of Low Pressure to develop out of the mean trough we will have sitting across the UK which could bring some very heavy rainfall and strong winds gusting 70mph along Southern coastlines. Details will of course change and further updates can be expected in the coming days.
