Nowcast Updates:

Sunday, 0900BST: The forecast evolution from the Met Office hasÌýproven very accurate, with the weakening cold front easing across Silverstone between 7 and 8am this morning. Rainfall radar suggested some isolated areas ofÌýlight showery rain in places around the circuit towards 7.45am. These, along with the frontal boundary cloud, have now passed SE and the skies continue to clear, withÌýwarm sunshine but a fresher feel compared to yesterday. Today's temperatures will be towards the mid-20's; it will now remain dry forÌýthe rest of the day and again somewhat breezy later.

Synopsis and Forecast Emphasis:

Being back inÌýthe geographical 'comfort zone' for thisÌýhome Grand Prix forecastÌýdoesn't necessarily makeÌýmy jobÌýany easier, but at least I've gotÌýaÌýsuite of detailed UK Met Office predictive products at hand for this one... plus their ever-helpful Chief Forecaster at the end of a 'phone!

One dominant thrust of the forecast will see rising temperatures across southern and especially southeast / eastern-central England later this week.ÌýFriday and SaturdayÌýwill see the highest temperatures; it'll certainly be a warm event throughout,Ìýwith some strong sunshine on Friday and Saturday especially.

In broadscale terms, the British Isles sees something of a NW to SE split developing later this week, withÌýareas further south and east across EnglandÌýremaining largely dry and warm; perhaps even hot in parts of the SE especially.

By the weekend, low pressure will beÌýskirting upÌýfrom the AtlanticÌýto the NW of the British IslesÌýand high pressure sitting across Denmark and Holland.ÌýTheÌýlocalised detailÌýfor Sunday, particularly in terms of shower potential, remains subject to flux but confidence in the broad thrust of the forecast is looking pretty good, with model continuity improving.

Friday will be dry, fine, very warm and humidÌýfor Free Practice 1 and 2, with strong sunshine developing and patchy fair-weather cloud.

It's a repeat story on Saturday forÌýFree Practice 3 and Qualifying: a glorious morning,Ìýalbeit with increasing amounts of high and mid-level cloud spreading slowly across Silverstone through the mid-afternoon. Moderately breezy at times; possibly a factor for qualifying, tending to unsettle the cars in various parts of the circuit.

Into the weekend, a trailing cold front will be draped SW-NE across theÌýwest of the British Isles. With a series of minor wave-like disturbances running up it, the front will tend to shift positioning, as will any attendant risk of showers or rain. It'll remain across W/NW areas ofÌýEngland during Saturday before slowly edgingÌýfurther SEÌýduring Sunday morning, bringing more cloud and offeringÌýa small chanceÌýaÌýlightÌýshowerÌýacross Silverstone around mid-morning.Ìý

The slow, southeastwards creep of this trailing cold front has been consistently signalled in recent output from the UKMO Global Model. The latestÌý(Sat. PM) detailed forecast assessment preparedÌýby the Met Office'sÌýChief ForecasterÌýoffers an essentially dry and fineÌýstory for Sunday, particularly the race window itself. Albeit an isolated light shower could develop around parts of Bucks and Northants through the first half of the day, as the fragmenting frontal boundary lingers close to Silverstone and temperatures rise, it is considered a low point probability. Once the front clear south, skies will then brighten-up by race start,Ìýto offerÌýincreasingÌýamounts of dry and sunny weather into the early to mid afternoon.

It'll certainly prove another very warm day, but a tad cooler than the previous two, as the very warm air across eastern/SE England gets squeezed away back towards the near continent. It'll again prove rather breezy at times.
