================================================== ==============================
=== This forecast represents the *PERSONAL OPINION* of the Chief forecaster at the privately run Haytor meteorological office in Devon on how the weather may unfold next week. The Chief forecaster will take no responsibility whatsoever for any actions arising from its use. It is provided freely in the spirit of freedom and the great love for meteorology that we personally enjoy and wish to share freely with others. ================================================== ============================== === Summary valid for Sunday 15/10/06 to Saturday 21/10/06 TOI (time of issue) Thursday 12/10/06 2100 UK local time This summary is based on a quick appraisal of the GFS, JMA, ECMWF, UKMO, FAX, and ENS (NCEP ensemble) labelled charts available from the superb http://www.wetterzentrale.de/topkarten High confidence that high pressure will become established to the NW of UK later in the week establishing a very cold north or northeasterly airflow across Britain by next weekend. Low confidence on details of change and on how fast the very cold air with night frosts spreads to southern areas. The daily breakdown below is a best estimate and timing could be out, but confidence in the sequence is moderate. Sunday looks like being a dry day in most areas but with a stiff east wind in southern counties. Possibly gusting to gale force near some hill summits in the southwest as air becomes trapped under an inversion. Lighter and mainly easterly winds further north. Spells of sunshine in all parts after an early frost in northern areas. Temperatures rising to 14C in the north and up to 18C in the south. On Monday little change is expected, except it will be a little cooler and the winds should ease in the south. Still some sunshine after a frost in places at first. However, showers are likely to develop in southern areas during the day. On Tuesday, showers can be expected to break out more widely with sunny spells in between. Some of them could be heavy and perhaps thundery. Winds probably turning light southerly over England and Wales, however, a cold east or northeast wind looks like setting in over Scotland, possibly bringing heavy rain and low cloud to eastern parts. Temperatures lower over Scotland but a little warmer again in the south reaching 17C in places. On Wednesday rain looks like setting in over most of Britain as colder air pushes south. Some of the rain looks again likely to be heavy and slow moving, so a risk of localised flooding. Temperatures starting to fall quickly in the north to around 10C and becoming close to normal in the south at around 14C. A strong to gale northeast wind establishing itself over Scotland as it turns drier. Winds lighter and variable further south but turning easterly later. On Thursday and Friday very cold fresh to strong north or northeast winds look like spreading south. These will clear the rain southwards eventually but still a prolonged spell of heavy rain likely in the south for a while. Temperatures plummeting in the cold air, falling to -2C at night in the north and by Friday daytime ranging from 7C in Scotland to 12C in the southwest. Showers setting in in the cold air, mostly to eastern and northern parts with some western areas turning sunny. Showers turning increasingly to sleet and snow over the Highlands. At this stage it looks like staying cold and showery into next weekend with some more snow for the Highlands. Risk of frost at night in all areas, even in the south. However, SE England could see another spell of rain as it turns slightly warmer again. Winds slowly easing over the weekend but low confidence on this.

But regular, as in most years and not just a dusting, doesn't appear until the second half of December. Most of November is pretty snow free. Odd bits through January, a big dollop end of Feb then pettering out by around mid march. -- Cheers Dave. pam is missing e-mail |
