Formerly known as United Kingdom Advisory Storm Forecasts (UKASF), Convective Weather is a voluntary-run organisation founded in April 2008, and run by a small team of meteorologists and storm chasers to provide daily convective (thunderstorm) forecasts for the United Kingdom.
Forecasts for convective weather are typically issued each evening and are valid for the whole of the forthcoming day(s). The forecasts are accompanied by a map with each threat level plotted as an overlay onto a zoomable Google map, alongside a static map for use in social media or forums. A detailed text summary highlights the regions at risk of convective weather, and explains fully the setup and conditions that may allow convective weather to occur.
Since 2014 we now issue forecasts, when necessary, for up to the next five days to act as a 'heads up' for any convective weather that may occur beyond the next 24 hours - this is, however, subject to forecaster availability and time constraints. The threat levels have been specifically created for typical convective setups experienced across the United Kingdom and cater for excessive precipitation, damaging hail, tornadoes and disruptive convectively-induced winds.
Since the service is voluntary, there may be occasions where forecasts are not issued, or issued later than normal. If no forecast is issued it must be assumed that this is due to a lack of forecaster availability, and that convective weather is still possible. One notable period each year when this is more likely to occur is during the months of May and June when our forecasters are likely to be storm chasing in the United States.
It must be noted that our products are intended to be used as a tool for highlighting areas that may exhibit some convective potential and do not serve as warnings; it is the responsibility of the Met Office to warn the public of severe weather.
Our small team of forecasters work for Weatherquest Ltd, based at the University of East Anglia in Norwich, and are fully-qualified meteorologists with experience in storm chasing. They are are also occasionally seen on BBC Look East and on BBC Local Radio in the Eastern Counties as relief weather presenters.
