We may well be shifting on to the autumn thread soon as GFS moves into the middle of the pack of the ensembles.
From GFS/GEFS point of view hot air looks to be increasasingly confined to the south east after Monday. With the transition comes the potential for some decent thunderstorms for parts of the SE and Midlands. More detail on that as we get closer to the time. It's too early to pin with any certainty.
I thought it would be fun to share this chart showing a hurricane out in the atlantic. It isn't modelled by GFS to come over us, indeed at the moment it loops back west. But this is two weeks away, way too far away in forecasting land!
ECM ensembles show a dip in temperatures, followed by a wide spread of ensemble members, demonstrating that the very warm temperatures may not be gone after this spell. Lots of uncertainty, as is always the case, particularly at this time of year, with an active hurricane season. ECMWF itself shows a faster cool down next week.
