Why is it turning warmer this Bank holiday weekend?
Over the end of this week and over the weekend the jet stream will move northwards of northern Scotland and over Iceland allowing much warm air to make its move nortwards. This will allow a area of High pressure then to build over Ireland and the UK over the weekend. Winds will be southwesterly in direction over this weekend.
The source of the warm air this bank holiday weekend is from the Azores region this is know as a tropical maritime air mass which comes from the warm waters of the Atlantic Ocean between the Azores and Bermuda. The wind direction normally associated Tropical maritime is a south-westerly wind.
