WeatherBlog 15 2016/17 | The groundhog says hello

Return to cool temperatures and lots of sunshine

by Lea Hartl 02/07/2017
After the wintry, more or less snowy interlude of the last few days, high pressure is now increasingly asserting itself again. There is still a bit of fluff in the southwest, but the remnants of the disturbances will quickly disappear. We are falling back into the pattern of the previous winter: Atlantic block, cold air from the east, unusually warm Arctic Ocean.

Current situation

The Mediterranean low, which recently caused precipitation on the southern side of the Alps and the main ridge, as well as minor disturbances in the east, will dissipate over the course of the day. The weather will now be dominated by an elongated Scandinavian high, which will block all disturbances from the Atlantic. The high will be supported and repeatedly regenerated by a low-pressure complex further west in the Atlantic, the front of which will advect very warm air far to the north. The WACCy pattern (warm Arctic, cold continents) continues and the sea ice extent at the North Pole remains unusually low - when extremely warm air is repeatedly shoveled in, freezing is not so easy...

Outlook

The high pressure barrier will keep the Atlantic weather out of Europe for the time being. Colder, dry, continental air masses will slowly flow in again from the east and calm and "foot-cold" inversion weather is likely to set in again, especially in the eastern Alps. A west-east temperature gradient will develop, with the west remaining somewhat warmer. It will generally not be quite as cold as in the sometimes very cold weeks of January. Apart from a few small and, as usual, very uncertain drops of cold air (the recently treated fat eyes on the inversion soup), there are no interesting or snow-suspicious developments in sight for the time being. On the entire southern slope of the Alps, it will remain somewhat more unstable and it may snow lightly from time to time, but I wouldn't expect much here in the near future either.

Long-term

We may not always spend the same day as Bill Murray in the best meteorology documentary of all time, but we somehow seem to be stuck in the same large-scale pressure distribution. It is therefore all the more pleasing that, despite all the political upheaval in the USA, Groundhog Day was celebrated there again this year. As usual, forecasts for the next six weeks were made as part of the festive event.

Traditionally, Punxutavney Phill, a woodchuck from Pennsylvania, and various colleagues emerge from their burrows on February 2. When they see their shadows (because the sun is shining), another six weeks of winter follow. This custom was introduced by German immigrants in the middle of the 19th century. In their homeland, the rule was "If the badger suns itself during Candlemas week, it goes back to hole" for four weeks. In the New World, however, there were no badgers available. Fortunately, it soon turned out that the many woodchucks there are also prepared to make long-term forecasts, at least when they are coerced into doing so by older gentlemen in top hats.

This year, the woodchucks' predictions for the rest of the winter are more or less in balance. Punxutavney Phil, Holtsville Hal, Essex Ed, Dunkirk Dave, Buckeye Chuck and French Creek Freddie are expecting 6 more weeks of winter. Malverne and Milltown Mel, Staten Island Chuck, Stonewall Jackson V, Chattanooga Chuck, Chesapeake Chuck and others see the imminent arrival of spring. Floriemel, Carmela and Margarita, three South American coatis from New Jersey with an affinity for meteorology, are betting on winter.

A Broadway musical for Groundhog Day is also planned for the near future. We're already very excited.

Here's the forecast from Punxutavney Phill at Gobblers Knob:
