GENERAL SYNOPSIS
Extended high that protects Continental Europe, 1030 hpa over Austrian Alps, will be refocusing towards 1040 hpa southwest of Ireland by Sunday evening, while its mild altitude component will be withdrawing over the Atlantic. This will pave the way to polar air inflow, Northwestern Russia to Abruzzo, by Tuesday evening. • Amazingly fair weather this week‑end in our Region : morning temperatures slightly below 0°C in the valleys, yet very mild atmosphere in the afternoon, especially on south facing slopes of the median altitude range. Then cooler condition will resume in the first part of next week, emphasised by increasing northeasterly stream high up, and partly sunny at times.
