UPDATE at 4.30pm:
Sheffield now has a new record with 153.4mm so far in April. Bingley has also broken its record, with 148.6mm.
Church Fenton in North Yorkshire has become the first station to report record rainfall following last night's heavy rain.
So far this month, 122mm (5 inches) has fallen, beating the previous record set in 2000 of 115mm. The station average for April is 49mm (2 inches).
Other stations are almost certain to break records with more heavy rain expected during Sunday.
Coningsby and Waddington in drought-hit Lincolnshire were at midday today less than 3mm from beating their station records.
But much more significant would be a new record at Sheffield Weston Park.
So far this month 150mm (6 inches) of rain has been recorded, just 1.5mm short of their record which was again set in 2000. Sheffield's average for April is 63mm.
This is an important climatological site with data which goes back to 1882 - making any records broken here very significant.
The persistent rain that has fallen this month, and in particular in the last few days, has unsurprisingly led to 10 flood warnings being issued on Yorkshire's rivers.
The catchments are now saturated and Sunday's forecast of heavy rain will be of concern to the Environment Agency.
The chart below gives guide as to the amounts of rainfall expected on Sunday from the Met Office Global model, although they could be underdone particularly in Pennine areas where an inch (25mm) of rain or more is likely.
Yorkshire Water say that bore holes in East Yorkshire have been responding to April's rain. At the start of the month, bore hole water levels were 20% depleted. At the start of this week they were 15% depleted.
The heavy rain of recent days and on Sunday is likely to improve the situation further - although there is still a long way to go before levels are anywhere near normal.
A respite to the wet weather is expected next week. With pressure rising conditions should be much more settled, with a good deal of dry weather likely across Yorkshire and Lincolnshire.
