Winter weather in Central Europe - Task List

Correct answer(s) is/are: A, B and C

On the front side of the cyclone in the western Mediterranean, there is a southerly flow with a warm advection and high amount of moisture. The warm front formation is visible over Italy and mid Adriatic. According to the synoptic situation, satellite data and prognostic material we can expect precipitation in all three areas.

Correct answer(s) is/are:
A - snow, freezing rain, sleet
B - rain
C - rain, snow, freezing rain, sleet

Above area B the temperature is above 0 °C through the whole column of air, since the warm advection is almost evenly heating up all the layers of the troposphere. We can expect rain.

The other two parts are a bit tricky. There is a pocket of cold air in the lower parts of the troposphere trapped by the orography, most persistent in area A. We can expect mixed precipitation snow, freezing rain, sleet and in area C also rain.

Correct answer is: A

Even though there is no extreme precipitation, the highest amounts are expected in the northernmost part of area A, 10 to 30 mm/24h.

Correct answer(s) is/are: A, B and C

Synoptic situation has not changed. The warm front is semi stationary. We can still expect precipitation during the afternoon and night.

Correct answer(s) is/are:
A - rain, snow, freezing rain, sleet
B - rain
C - rain, snow, freezing rain

The situation above Area B has not changed, therefore we still expect rain.

The warm layer at 850hPa is moving more to the north. In Area C we mostly expect rain, but in a small area near the Slovenian border conditions for mixed precipitation still exist and towards the middle of the night they are especially favorable for freezing rain.

The 'cold pocket' in lower levels is most persistent in area A. There the precipitation will be most diverse.

Correct answer is: A

When looking at the model output data, it seems that the amount of precipitation is similar for Area A and B, while the amount for Area C is much smaller.

Correct answer(s) is/are: A and C

There is a need for winter weather warning in Area A and C, not so much because of the amount of precipitation but because of freezing rain possibility.

Correct answer(s) is/are: A, B and C

There is still a high amount of water vapor above Croatia. Tomorrow, the cyclone will be moving more to the south, therefore during the night and morning we expect precipitation which should diminish during the afternoon.

Correct answer(s) is/are:
A - rain, freezing rain, snow
B - rain
C - rain, freezing rain

Temperature at 850hPa is above 0 °C above all areas, we expect melting of ice crystals and no snow. However, if you take a look at the vertical cross section for the most northern part of Area A (Ogulin), you can see that the forecasted temperature at 850hPa remains around 0 °C till midnight. Therefore during the afternoon, there is a small possibility for snow.

In area C we can expect rain or freezing rain, but here the freezing of rain droplets is because of a different reason. Here relatively warm rain droplets might freeze on contact with the cold surface.

Correct answer(s) is/are: A and C

There is a need for winter weather warnings in Areas A and C (localized warning for western/border part).
