• NCIC Monthly Summary

  began frosty on the 17th, with fog in places, and some sunshine followed for all but the north-west. The 18th was broadly frosty to begin, with mist and fog covering the bulk of the country, clearing only slowly if at all in some spots; otherwise cloud amounts were variable with long sunny periods

  . The weather variables in a microclimate, such as temperature, rainfall, wind or humidity, may be subtly different to the conditions prevailing over the area as a whole and from those that might be reasonably expected under certain types of pressure or cloud cover. Indeed, it is the mixture of many

• Fourth convective scale modelling workshop

    The representation of fog, cloud and rain processes in regional modelling is of fundamental importance for both NWP and climate, particularly at “convective” resolving scales. This session will include talks and discussion covering; fog and visibility,  microphysics (both cloud and aerosol), aerosol-cloud

  potentially reaching the high twenties by Thursday and possibly approaching 30°C in the southeast on Friday, depending on cloud cover and other variables.  Alongside the warmth, there will also be spells of rain, particularly across northern and western areas, and an increasing chance of thunderstorms later
