Go to
here and enter EGTE in the box, select Meteogram 0-180hrs, then Choose from Below, and check
MSLP (SFC)
Temp (2m AGL)
Accm Precip (SFC)
Total cloud cover (SFC)
Wind flags
Wind speed
or whatever (but you can't mix 2D and 3D items on the same graph).
Wed 7th March looks like the cloud will be on the deck, rain, and from the wind change mid-day it looks like a front will be passing through.
The above is from the GFS model.
The UKMO MSLP charts don't go up to 7th March so one can't cross-check.
Repeat the above for a few locations along the route, and for the destination.
I wouldn't plan this flight VFR.
However, forecasting 6 days ahead in the current unstable weather is impossible.
