Radiation fog in valleys

Another 5.1mm of rainfall was recorded in the past twenty-four hours that took the monthly total to 89.6mm being 28mm above the 39-year average. The warmth was limited by day and night with extremes of 17.3C and a very cold night with 6.3C being 2.6C and 3.0C below the average respectively.

Friday revealed radiation fog in the River Og and Kennet valleys was thick by daybreak and didn’t disperse unto shortly after 08.00 as the sun got to work. This fog forms as the air cools in the lower level of the valleys where the higher air moisture content condenses.The depression is easing away to the the north as a ridge of high pressure begins to arrive from the south.
