Yet another snow-free November (third in a row)

Nothing too anomalous; snow usually appears in Warsaw towards the end of this month. Other than the briefest flurry last Monday and a brief dip into freezing temperatures on Wednesday morning, this November has not brought much by way of wintery portent. It has been wet and dull this week, weather that does nothing to lift the spirit.

Yesterday in Katowice, the thermometers in the streets showed double-digit temperatures, it's colder up here in central Poland with a daytime high of +4C and steady light rain.

Below: ul. Trombity, Monday morning; a light frost, a few flakes of snow would fall later in the day.

Here in Jeziorki we are keeping our fingers crossed for a winter that's light on snow. The main sewer has been laid in the street outside and into our estate, but now each house has to be connected to it. Work will not commence until after winter; the more snow falls, the more waterlogged the earth will be, and the more complicated (and expensive) it will be to dig the trenches from under each house to lay the waste-water outfall pipes linking our plumbing with the sewer.

Below: late November Warsaw city-centre skyline. Five to four in the afternoon.

The heaviest snowfalls can be expected between mid-December and mid-February. So a snow-free November is meaningless, and predicting future months' weather on the basis of this one is futile.

This time last year:
Another November without snow

This time two years ago:
Snow-free November

This time three years ago:
Krakowskie Przedmieście in the snow

This time four years ago:
Ul. Poloneza closed for the building of the S2
[four years later, the Poloneza is open, the S2 is open]

A very wise comment at the very end. The predictive value of weather in November (average temperature of +5.6C, I surmised, it would be record high, while it was colder than in 2012 (+5.8C), 2010 (+6.0C), 2009 (+5.7C) and 2006 or 2000(+5.9C)) is close to zero - there are no statistically significant interdependencies between weather patterns in subsequent months.
