I've just given a friend a forecast for Sevenoaks in Kent where he is playing golf today, saying dry. Imagine my shock when I looked out of the window and saw puddles on my flat roof. Checked the radar - nothing at all. On high res some very light small patches around your area but nothing in Essex or Kent! Dave, S.Essex |

Always misses soaking heavy drizzle which can give several mm in the gauge and sometimes overdoes convective rainfall.

Are you going to, or have you done your Dartmoor winter forecast yet Will? Dave |

It has its well-documented limitations. Yes and also the performance depends on regular maintenance and software corrections. That costs money.

This has certainly happened the in the past. Fairly continuous but light drizzle here up to now (1130). No hill fog. Tudor Hughes, Warlingham, Surrey, 557 ft, 169 m. |

Drizzle isn't picked up by radar. There's more info on http://www.metoffice.gov.uk/learning...rainfall-radar. The Met O is upgrading their radar network but whether this includes drizzle I don't know. There used to be a very good page describing the strengths and weaknesses of weather radar but I can't find it at the moment. |

The forecast was also for dry so the human intervention didn't work either. Today bears no resemblance to the impression given by last night's forecast which was for a windy, mild dry day prior to the rain band arriving later. |

![]() Hi Dave, gave them up a couple of years ago. I now do a 4 week ahead outlook each week along with my weekly forecast.

Will ----------------------------------------------------------------------------- Good, I'll have a look. Think the 4 week trend is more realistic and useful. people tried to read too much into the other one which was just for fun really. Talking of which things seem to have settled down on here of late - let's hope it lasts, we all need a bit of good will (no pun intended) at the moment. Dave :-) |
