Twice a week I get maps from a 30 day ECMWF run. 1 map for each week with the 500mb heights averaged out for the whole week. Obviously this smooths out deep lows or fast moving troughs or ridges, but it gives us a good idea of what general weather pattern might be headed our way. Specifically, last night’s run shows troughiness (cooler than average weather) through most of the rest of the month. Here are the first two weeks:
Then the following two weeks, which takes us into early April.
