An unusually precise forecast from Weather Action:



"What will happen to that DEEP LOW 15th (currently similar to 12th on

Forecast maps)?



WeatherAction Answer. It will NOT be as severe as MO say. The Central

pressure 960 mb at 00z 15th over Eire/Irish sea will be higher, and

the centre will not have advanced so fast. The system will fill

somewaht (sic) as it proceeds from now (13th 11z). The reason? We are

now moving from an R5 into an an R3 period and Standard Met cannot

well forecast out of an R5."



What are R5 & R3 periods, anyway?
