Time to explain troughs and ridges. These are especially noticeable in the winter months.
This will give you a basic understanding as to why you can be so warm or cold in winter.
Keep in mind, I can only show/ explain this using my non-expertise. That bring said, what I will show/explain here, will still be right.
Basically, if you are north of a ridge, then you are in a trough, so you will experience cold weather. If you are south of the trough, then you are in a ridge, so therefore, you will experience warm weather.
Generally, if there is a trough in the eastern part of the country, the western part of the country will be in a ridge.
If there is a part of the country that is not in a trough, then they will be in a ridge. Vice-versa with ridge.
On the map below: North of the black line, you are in a trough. That allows cold air to come down from Canada, and prevents warm air from getting in.
If you are south of the black line, you are in a ridge. Which does not allow cold air to get passed rather, it allows warm air to come up.
