Climatic bag

Today I heard a new term about the weather. I watched the weather forecast and a weatherman said that central Russia was in a climatic bag.
I live in Moscow and here the weather is the most popular theme for discussion. Today is 7th July, and the temperature is only +14'C. The normal temperature for this time of year is +25'C. Almost every day it's raining, and strong winds blow.
In May it was snowing in Moscow! I have never seen such snow here in May!
Why are Moscow and other cities in the climatic bag? I've heard that it's really hot in some parts of Europe* and recently it was extremely hot in Siberia. And Moscow is situated between these hot parts. The weather doesn't change, it isn't getting warmer. That's why we are in the climatic bag.
What do you think about the weather? Do you agree that the weather is changing now? What's the weather like in your country?**

*this is true for London. It is hot here now. **too hot.

Very well written!

Climatic bag

Today I've heard a new term about the weather. I watched the weather forecast and a weatherman said that the central part of Russia was in the climatic bag (I've never heard of this term, it may be expressed differently in English and not a direct translation).
I live in Moscow and here the weather is the most popular theme for discussing to discuss. Today is 7th July 7th, and the temperature today is only +14'C (usually expressed as 14ºc, you only need to add +/- if it's below zero). The normal temperature for this time is 25ºc. Almost every day it's raining (also could be said as "nearly everyday it rains), and strong winds blow.
In May it was (right here, to add emphasis that this is a strange occurrence, I would add the word "even" or "actually") snowing in Moscow! I have never seen snow here in May!
Why are Moscow and other cities in the climatic bag? I've heard that it's really hot in some parts of Europe and recently it was extremely hot in Siberia. And Moscow are is situated between these hot parts. The weather doesn't change, it isn't getting warmer. That's why we are in the climatic bag.
What do you think about the weather? Do you agree that the weather is changing now? What's the weather in your country?
