| Satellite picture of Northern Hemisphere / Atlantic: Sunday, 23.01. 1815 UTC |
This constellation of H's and T's will know that! Since the large-scale conversion to four days of the mild west flow to a much cooler north North West hiking weather the lows again around the wide wedge pressure over the eastern Atlantic and discharged preferentially to north of the Alps (similar to early-mid December). Also seen in this satellite picture is the way to the extremely cold air thrust on the U.S., the minimum temperatures below - has caused 40 degrees (- to 43 degrees to be exact: International Falls, Minnesota ).

A too small country ...
Austria like a narrow, his small country (just under 570 km maximum horizontal dimension), but technically it is wetter in the coming hours and days if not two of three parts. The third West is retreating under influence of high pressure dry most especially during the night BITTER COLD. The historical record values range from -20 to -25 degrees and are thus out of reach tonight.
Current values (23 GMT):
Ehrwald: -16 degrees
Bichlbach: -15 degrees
Seefeld: -15 degrees
Schoppernau: -14 degrees remains
Also in the south it (thanks Leeeffekt) usually dry and partly sunny. With any significant new snow is probably to be expected until next weekend.
snow from Tyrolean lowlands along the main Alpine ridge to the Vienna Woods, however, it frequently until Tuesday morning, and sometimes also strong. It focuses on increasing congestion in the North West Salzkammergut, the beautiful countryside and the Eisenwurzen.
balm on the wounds mild?
The current cold (and completely comply with end of year) the previous mild temperatures in the same month of January only marginal.

| deviation of the January temperature (01-23.2011) of long-term average |
Unlike the situation in precipitation (not shown): the clear Increase of 25 - 40% of the Salzach river to the Ybbs is the result of the ongoing North (west) congestion situation and the dramatic event of the Warm Front last week. Right here will go down in the next 48 hours, the bulk of the snowfall.
Thus, while the cloudy northern Alps margin was too shady (distributed only 60% of the average sunshine duration ) were found mostly in the West (Feldkirch +30%) and in the far north (Weitra: +40%), the sun often. As the sunniest regions crystallize until now, the Styrian hill country south of the out-Mür Murz-Furch (100 - 110% of target) and the higher areas in Carinthia (Friesach in the Gurktaler with just under 20%).
