it all depends, its either an upgrade or a big downgrade for many northern areas.. the gfs 18z has the band fragmenting and slowing down as it hits the southern parts of the midlands. If this is the case when the precipitation does arive for lincs,yorks, nottinghamshire/northampton area, it could be so light and patchy plus with + dew points and the cooler pool of 850's shunted further north, it could be very marginal indeed, going by the 18z i would say it will hit for around 10:30am to 11am. Going by the metoffice radar i would say a little earlier around 5:30 to 6:20am.
If it hits before 9am, it should be ok!
Fingers crossed
