I’ve been a bit behind at work (and uninspired by the weather) lately, but I come bearing gifts. Last night’s ECMWF monthly run: 4 maps, one for each week, showing the average 500mb (upper-air) pattern. Yellow/red areas are higher than average (usually warmer), and bluish areas are troughy or cooler than average.
Here’s the 12z ECWMF ensemble chart too, showing the cool airmass later this week and then a rebound to average or a little above after that time:
