Been quite the run of days for CET projections. For a while there were some bonkers GFS runs giving me estimates of more than 18.0°C for the middle days of the month. Not for the daily returns, the mean-to-date! Would be record high for that point in the month.
Anyway, since then GFS has freshened up the weekend and has only intermittent very warm weather thereafter, so CET estimates aren't so eye-watering. They're still notably high though, owing to the impressive very warm / hot spell we're currently in and a lack of sustained switch to a cool pattern in most runs.
ECM was going for warmer but more unsettled outcomes than GFS yesterday but has moved close to it today. Sunday morning could feel decidedly cool as some polar maritime air moves though on a light breeze.
It soon warms up the following week, though. Generally I'm not seeing anything that would force a sustainably cool or very cool pattern to establish within the next fortnight. I'm starting to suspect I may have estimated too low for this month - but then again, I thought that about halfway through last month and...!
