You are listing capital cities and major regional centres as having forecasts with less than reliable accuracy.
Try flying in Australia's GABA, where the forecasters haven't got a clue and (I suspect) couldn't give a firetruck......and at the planning stages of the day (ie 5am) to have NO TAFs in regional areas. We have been known to wait for the duty forecaster's coffee to kick in sometime after 6am before we get the luxury of a TAF.
Has been known to happen that the TAF at 7am says CAVOK, while those at the airstrip are watching from behind closed hangar doors as a massive thunderstorm rattles overhead and lightning obliterates a tree 5km from the airport. Or we stagger off into CAVOK on a crystal clear morning, while the inbound RPT flight crew has a second cup of coffee in the capital city because the TAF says 50% FOG.
Any complains to BOM are met with the bland statement - Regrettably, forecasting is an imprecise science.
