Here is a summary of the NWP output for 12z on Monday.
Issued 0536z, 31st May 2007.

High pressure will be in charge for the first half of next week, with all
areas seeing drier conditions than of late. Although the winds won't be from
a warm source, under largely clear skies temperatures should still reach the
"warm" category in many areas, although eastern areas exposed to the onshore
breeze may stay cooler. The models then suggest the warm weather continuing
towards the weekend, although possibly with showers moving up from the south
as the high declines.

followed by NE'lies for most on day 7 as the high moves over Scotland.
