In response to a strong warm advection ongoing along the northern flank of the west-central Europe ridge, dry foehn effect warming occurred over the west Norwegian fjords. Several stations reported around the mid 10s peak afternoon temperatures. The station Sunndalsøra which set a new national record on January 2nd has reached another very high temperature, +16.9 °C this afternoon.

As we remember, the weather station in Sunndalsøra set a new Norwegian record on 2 January with +19.0 °C. This afternoon, the same station has reached 16.9 °C, resulting from dry winds from the mountains into the valley/fjord. A new record has also been set for Trøndelag region, station Rissa hit +14.0 °C, breaking up the previous record of +13.8 °C observed in Vinjeøra in 1971. +13.5 °C has been recorded in Skjetlein near Trondheim – this ties the highest ever January temperature in Trondheim.

Some other high January values today:

+14.2 °C – Rekdal
+13.2 °C – Orkdal Thamshamm

The next 12 hours will also be very warm over the Baltic region and southern Scandinavia, as strong warm advection is spread from the west. Between an extensive upper-level ridge and the deep cyclone to the north, strong westerly flow brings 12-16 °C warmer air mass through the lowest levels tonight:

Close-up view of an impressive temperature anomaly across Scandinavia and Baltic region tonight – 12 to 16 °C warmer air mass is spread across the region:

High winter night temperatures are likely across the whole region and especially across south-central Sweden and Finland – as high as +8 °C in some areas through the middle of the night:
