Spring has finally sprung today with large parts of East Anglia seeing blue skies and bright sunshine but it is not expected to last.
Temperatures peaked at 17C at Writtle in Essex well above the average temperature for this time of year of 8C.
There were highs of 16C at Santon Downham and Tibenham and the thermometer reached 15.5C at Marham.
James Wilby, of Norwich-based forecaster Weatherquest, said the pleasant weather is down to a south westerly flow.
'North Norfolk is being hit with northerly flow which is why temperatures are slightly lower at 12C and 13C but further inland the region is benefitting from a south westerly flow which feels a lot warmer as it has travelled across land which is generally warmer than the sea at this time of year,' he said.
Tomorrow is going to be another mild day with highs likely to be 14C or 15C. On Friday it will feel notably fresher with temperatures peaking at 11C with showers and stronger winds forecast for Friday night and Saturday morning. Between 3mm and 4mm of rain is expected to fall and temperatures on Saturday will peak at 14C.
There have been concerns that Storm Stella, which has battered northeastern states in the USA, could bring disruption to the British Isles but Mr Wilby downplayed those fears.
'It is currently sitting north of the British Isles near Iceland and we may see some wind and rain from it but at this stage we are not expecting any severe conditions,' he said.
