GENERAL SITUATION AND SYNOPSIS
21:00 UTC 03/07/2009
Pressure is still relatively high to the east, and low to the west of the UK, However, as the remnants of a weakening front - at one time marking the division between very warm Continental and cooler Atlantic air - moves over the Northern Isles, somewhat fresher and showery conditions will displace the hot and humid air eastwards.

Filling low pressure will drift east over the UK later in the weekend, with a N'ly airflow developing by Tuesday as it moves away into southern Scandinavia. By midweek - with pressure building to the west - the airflow is expected to be N to NW'ly in direction.

Later next week, we may see pressure again building over the UK.

DISCLAIMER
This outlook is based on an appraisal of the charts and ensembles from GFS, ECMWF, UKMO and FAX available via the internet, and over 30 years of local weather experience.

Be aware that the weather over north-west Europe - and especially around the Northern Isles - is part of an ever-changing and dynamic system. Therefore regard the 10-Day Outlook' as a guide only - there are times when any outlook going beyond about 36 to 48 hours is likely to prove unreliable.

Always check the latest forecast from the UK Met Office before undertaking any weather-dependant activity.

All forecasts are for planning purposes only.

Neither Dave Wheeler, nor any employee of Fair Isle Weather Services, accepts any liability for the accuracy of this forecast.


Please note that this page is usually updated every day (around mid-morning) but on occasions updates may be irregular. A daily service by e-mail is available, but is charged for.

If you wish you can have the 10-day Outlook e-mailed to you free once a week (usually at the weekend). Please contact Fair Isle Weather Services for further information
