Monday, September 20, in Moscow and the Moscow region, a third of monthly precipitation could fall. There hasn't been so much rain in the capital for over 73 years. About this great specialist of the meteorological center “ Phobos & # 39; & # 39; Evgenia Tishkovets posted on her page in & nbsp; Facebook.

“ In the Moscow region, most rains are expected in the western, southwestern and southern regions (Mozhaisk – 21 mm, Serpukhov – 20 mm, Naro-Fominsk and Stupino – 18 mm). In Moscow, up to 16-21mm of rain can fall, which is up to 1/3 of the monthly norm. There hasn't been such heavy rain that day (September 20) for at least 73 years, if not longer. Comparable, but less intense (13mm) showers were only recorded after 1948 in 1952 and 1959, '' Tishkovets wrote.

Where does the downpour in the capital come from?

The reason is a powerful North Atlantic cyclone that attacked the western regions of Russia the day before, and only in the last 24 hours has caused monthly rainfall in places.

“ This cyclonic armada of rain, cold and wind goes slowly, at a speed of 10-15 km/h, moving with an easterly heading, covering with its rainy influence almost the entire southern half of the Russian plain. Center for the atmospheric funnel will go to the west of the Bryansk region. The heaviest precipitation will be associated with a warm atmospheric front, the line of which will cross central Russia and the Chernozem region, ”Tishkovets added.

In addition, a cold north-easterly wind will blow over Moscow with instantaneous gusts up to 17 m/with. The air temperature at night will be only + 3 & hellip; +5, and during the day it will not exceed + 5 & hellip; +7.

This weather is not typical for September. According to the forecaster, the weather on September 20 will match the climate on October 16.

“ Nature will take us into the climatic future a month in advance. In such unfavorable conditions of strong wind and rain, the Baltic will also work. a syndrome where Muscovites will feel like it's colder outside than it actually is, ”Tishkovets explained.

In which regions can wet snow fall?

The cold October and the first wet snow early in the coming week will be felt by residents of several regions of central Russia, Tishkovets noted.

So, on the morning of September 20, wet snow mixed with a downpour can pass in places in the Moscow region (Sergiev-Posadsky district), in Tver and in some districts of the Tver region (Ostashkovsky districts , Vyshnevolotsky, Rameshkovsky, Nelidovsky) and in the Yaroslavl region (Pereslavsky district).

“ The collision of hot and humid Atlantic origin air and continental cold (last night's frosts were recorded in the Upper Volga region) will not only result in abnormal precipitation, but also the likelihood of their transition to a mixed phase. Under 'borderline' conditions weakly positive between phase transitions in air temperature (around +3), there is a theoretical probability of mixing rain with mosaic ice pellets in the short term, ”the forecaster said.

On Tuesday, September 21, according to the center Phobos, sleet, in addition to the western Tver region (Zharkovsky, Zapadnodvinsky districts), will be observed in the north and the ; western Smolensk region (Velizhsky, Demidovsky, Yartsevsky, Safonovsky, Dukhovshchinsky, Krasninsky districts).

“ Of course, the hypothetical snow will immediately melt when it falls, it is always in the air and the overwhelming majority of the people of central Russia won't notice it, ”Tishkovets said.
