Lerwick (S. Screen) (Shetland Islands) weather

Headline:

Early wintry showers on Thursday, otherwise dry and cold Thursday.

This Evening and Tonight:

There will be a mixture of clear intervals and wintry showers of sleet hail or snow, which may give a slight covering in places mainly over higher ground. Strong northwesterly winds. Minimum temperature 0 °C.

Thursday:

Wintry showers becoming isolated then dying out, some sunny spells as the northwesterly winds ease. Cloud and light rain will arrive in the evening with strengthening southerly winds. Maximum temperature 6 °C.

Outlook for Friday to Sunday:

Friday and Saturday will bring clear or sunny intervals and showers, with strong winds at times. Wet and windy for a time on Sunday then brighter with showers later.

High pressure to the southwest of the UK will likely be the dominant feature for this period. This will lead to a fairly blocked pattern, with weather fronts rounding the high to affect northern parts at times, where wet and windy weather can be expected. Further south, drier and more settled conditions are more likely, as frontal systems weaken as they meet the high pressure. Through the period, high pressure is likely to spread across much of the UK leading to settled conditions developing more widely. Whilst temperatures will be generally near to or a little above average, some colder interludes are possible, especially in the north, where there could be some wintry showers at times.

High pressure will likely be dominant at the start of this period. As such, plenty of dry weather seems most likely, but with changes in wind direction leading to some quite marked differences in cloud amounts and temperature from day to day. Moving further into April, there is a chance that high pressure will become less dominant and thus there is a greater chance of more places seeing some rain and possible stronger winds from time to time. Overall, temperatures will likely be near to average.
