, particularly over coastal areas and hills where it brings low clouds, drizzle and local hill fog. Judging from the number of isobars the gradient wind does not seem to be an issue but the complexity of the frontal system over the Atlantic indicates that conditions will deteriorate quickly

the air stable, rather than cold and moist. Low cloud and poor visibility may be very persistent under such conditions. • The record breaking temperatures of August 2003 were caused by a tropical continental air mass. Summer Winter Temperature: Very warm or hot Average Humidity: Relatively dry Rather

. Breezy conditions will persist, and temperatures will hover near or slightly below seasonal averages. Monday night will see a shift to drier conditions for many, though showers in the north will drift southward, concentrating along North Sea coastal counties. Cloud cover will increase in the far

to the formation of cumulonimbus clouds, towering, dense clouds capable of producing heavy rain, hail, and lightning. Lightning is a massive electrical discharge caused by the separation of positive and negative charges within a storm cloud. As the storm develops, ice particles and hailstones collide

spring on record. Mean temperatures for spring were just ahead of the previous record of 2024, whilst the record sunshine hours surpassed those of the Covid spring of 2020. The late burst of Atlantic mobility was sufficient to bring monthly rainfall totals across parts of the north Midlands, northwest

smoothed power versus range of real radar data contaminated with RFI. • Presence of interference pulses from several sources is visible from 40km, where the power level of the received echoes is below the RFI.

of the atmosphere model to the surface model, where soil moisture has been shown to affect initiation. Much of the above is based on comparisons between model and observations for surface rainfall. It is possible that updrafts or clouds may compare better to observations and that the issue is related

also see isolated highs above 30°C. Elsewhere, temperatures will generally range from the low to mid-20s Celsius, with Shetland remaining cooler in the mid to high teens. Coastal areas, particularly in southwest England and Wales, will feel cooler compared to Tuesday. Medium-level cloud may produce
