Lack of precipitation East Dorset
Posted: Fri Jun 15, 2018 3:24 pm
... With a groan I heard one of our illustrious weather presenters recently trot out the phrase ... "much needed rain", when discussing a cold front swinging SE'ward over England. Said front produced 0.1 mm of rain here.
We are beginning to experience a marked deficit in rainfall hereabouts. The recent 'winter-half' precipitation [October - March] for us represented 91% of the LTA, and it was only thanks to a >200% out-turn in March that the figure wasn't lower.
April was also wet (166%), but by then of course the evapotranspiration (ETp) figures are climbing sharply. And both May (59%) and this month so far (just the aforementioned 0.1 mm) have been notably dry, when the ETp figures are, on average, around 80 - 90 mm per month; we had a spell of low RH/ east-northeasterlies recently which must have locally enhanced those figures.
The output from longer-range models (e.g. GFS) don't offer much relief this month, and neither do the GPC/MetOffice outputs for June, July, August.
Could be an interesting situation developing for the southern part of England/Britain .... anyone else got thoughts on this?
