22-28 Oct 2012 - Settled Week, Turning Colder By The Weekend

COMING WEEK: Mild to start with but turning much colder.

A quiet spell of misty but otherwise fine autumn weather will dominate much of the coming week in both Ireland and most of the U.K.  Temperatures will peak at 12-16 C during Tuesday to Thursday. Temperatures will be a few degrees lower where fog/mist lingers. 

As The Meteo Times indicated on Wednesday last, we will see a transition to colder weather by Friday (26 Oct), which will last into next weekend. Some wintry precipitation is possible on higher ground in northern parts later on Saturday night with some wintry showers of hail or sleet possible at lower levels in the northern half of the country during Sunday (28 Oct). 
The extent and longevity of this cold spell is far from certain due to a divergence in the output of the main weather models. All agree however, that temperatures will return to single figures during the daytime from Friday with the mercury levels dropping below zero away from coastal areas on Friday night and Saturday night.

The featured image (above) shows 850hpa temperatures (temps at approx 1500m) on Friday afternoon and 2M temps (close to surface temps) on Saturday morning.

Present indications are that temperatures during the first week of November will be at or slightly below average with further night-time frosts likely.Rainfall amounts are expected to be below average for the time of year. This outlook is backed up by the below graph from Meteociel.fr.
