Spring blues: Cold outbreak cools down week ahead

A significant cold outbreak has made its mark in the rest of Europe, but forecasting websites predict another deep trough that will deliver a very cold airmass far south into the Mediterranean

Weather forecasters are insisting that a significant ‘Arctic cold outbreak’ be pushing into central Europe, the Balkan peninsula and right into the Mediterranean early next week after the weekend is over.

The significant cold outbreak has made its mark in the rest of Europe, but forecasting websites Severe-Weather and Malta Weather have both predicted another deep trough that will deliver a very cold airmass far south into the Mediterranean and the Balkans.

The well-established pattern sees a cold airmass developing on the eastern flank of a strengthening upper ridge across western Europe and the North Sea on Saturday and Sunday. A very significant cold outbreak then pushes towards continental Europe, with a strongly meridional northerly flow as a powerful upper ridge establishes over western Europe and the north Atlantic.

The very cold airmass will spread across eastern Germany, the Czech Republic and western Poland towards Austria and the north-west Balkans on Sunday. It continues spreading across the whole of Poland on Monday, as well as across the western Balkan peninsula and partly over Italy. On Tuesday, the peak of this cold outbreak will be reached and will be centred over the Balkans with temperatures up to 15°C below average for this period.

The cold airmass will also spreading into the southern Mediterranean. Through mid-week the cold will start diminishing, but Wednesday still remains very cold over the Balkan peninsula and towards Poland, as well as Italy and the south-central Mediterranean.

By Monday, the upper ridge pushes also into northern Europe and closes the pattern with a large cut-off low, developing into south-central Europe. The cold airmass is already over-spreading the Mediterranean by this time, with the lowest temperatures at mid-level are expected on Tuesday. The cold outbreak starts weakening through mid-week, while the West Mediterranean will remain very warm, especially around Spain where a very first heat wave of the year is expected to develop.
