The Met Office may have purposely forgotten to issue a strong wind warning for Philine yesterday, but the NWP model must have been indicating some heavy rain for Northern Ireland so they did issue a yellow warning of heavy rain for the province (fig 2). As you can see there was indeed some intense heavy rain, with rainfall rates of over 32 mm per hour at 1810 UTC (fig 1) close to where low Philine was developing a discrete centre. This shows you just how good the NWP models can be.
Weather Radar Estimates
As far as I can see from my estimates from weather radar images there was a largish area with totals in excess of 50 mm for the period 10-1200 to 11-0845 (fig 3).
Evidence from the rainfall gauge
It’s clear from the gauge network totals for the 24 hours ending 06 UTC (fig 4) that the weather radar may have been over doing the intensity of yesterday rain for some reason. The freezing level was low enough for the rain to be falling as snow down to low levels ~2500 feet, so the white intensities (fig 1) could have been some form of bright banding effect.
The warning itself was just about perfect for Northern Ireland, but there were even higher totals across northwest England and southwest Scotland that didn’t get a mention.
