Strip of forecasts below (left column) shows 48h maximum gusts from successive HRES forecasts from DT 00UTC 21st through to 00UTC 27th (left click, then right click -> view image to get full resolution), for VT period 06UTC 27th to 06UTC 29th. Note how the early forecasts jumped around, as one might expect. Later on very extreme gusts were forecast for areas SW of the UK, and as the event approached this zone of extreme gusts migrated its way eastwards, which is perhaps not what one would want/expect. End of period mslp is also shown.
By 'adding together' equivalent plots from two very short range forecasts we can provide a model-based pseudo-verification to compare the above with. These are provided below in rapid animation and two-up formats (covering the period 18Z 27th to 06Z 29th). No gusts of note were forecast for the 06Z-18Z 27th period.
