October 1 2012.

It's Long Jump time again.

Fairly unsettled weather today. Rain in the south and the same for northern areas later.

Monday 1 October—Sunday 7 October

A northwest/southeast split?

This week looks likely to bring a transition to a westerly or southwesterly flow, although there is a hint in some of the models that the pressure will build for a time in the south. If this happens it could be a signal that a northwest/southeast split is on the cards.
This would mean the north and west would see the bulk of the unsettled conditions with wet and windy weather in store. The south and east would see more in the way of bright and dry conditions but also cold nights with mist or fog at times. Alternatively if the pressure fails to build, the whole country would experience a mobile set-up bringing spells of wind and rain.

Monday 8 October—Sunday 21 October

Business as usual?

By the middle of October we look likely to see the type of weather that might described as typically autumnal. Although there will be some drier, brighter spells these will probably be punctuated by showers and longer spells of rain.
Once again the north and west looks most likely to see the majority of the wind and rain with the southeast more favoured for something drier and brighter. Temperatures will probably be fairly typical for the time of year with some cold nights likely, with mist and fog at times as well as the chance of wintry showers in parts of Scotland.
