The CET will reach its lowest point for the month after today when I calculate it will be at 4.38C. A slow rise starts tomorrow before things begin to accelerate. Currently I expect the CET to reach 6.11C by the 25th.
Could be looking at a similar CET figure to February 2011 and 2014. Both those years saw a very warm Spring with April 2011 of course setting an all time record.
If we look back at other years recently where the Feb CET has been above 6C we see that generally March is also a very warm month. For example, 1990, 1997, 1998, 2000, 2002, 2014. The only exception was 1995. Prior to 1990 you have to go back to 1961 to find a Feb CET more than 6C. That year also saw a very warm March. Same story for 1945.
So I would say that if this mild second half of February verifies then we are odds on for a very warm March as well.
