Day 31 - last chance.





A pretty decent day is in prospect for much of Britain and Ireland today, especially when compared to what is heading our way for tomorrow. Low pressure is the main driver of our weather at the moment, but for most of us today, we will be in-between weather systems.

There is some residual cloud and patchy rain now clearing through East Anglia and southeast England, and then most places will see a dry day with sunny spells developing. There will be some showers feeding into the north and west of both Ireland and Scotland, and one or two of these may be on the heavy side as well. Temperatures generally still on the mild side, but not quite as mild as it has been, and with the sunshine it will feel very pleasant. This takes us into a generally fine evening for the trick 'n' treater's, although rain will quickly sweep into the southwest of England and Ireland as the next low begins to move in.

Things go downhill quickly tonight as that next weather system gets closer, and this is the one that has been causing us some concern. There has been a lot of divergence from the forecast models over the behaviour of this system, but they finally seem to be coming to agreement now. It is expected to track north-eastwards across Wales, central and northern England, bringing heavy rain with it. By the end of the night, much of England, Wales and Ireland will be very wet, with the rain also moving into Scotland by tomorrow morning. Winds aren't expected to be too much of a feature, although coastal gales may affect the south for a time. Our Weather Watch has more details.

The rain will continue to move northeast tomorrow, with brighter conditions and scattered heavy showers following into most of England, Wales and Ireland. For Scotland though it looks like being a thoroughly miserable day with the rain persisting. Winds will pick up in most places for a time as the low moves away, and it will start to feel colder as those winds veer westerly.
