The cold weather continues with another ice day being recorded at Pitsford. Temperatures during the afternoon hover just below freezing with a maximum of -0.1C. Patchy mist and fog also lingers in places throughout much of the day.
Above: a common feature of the current frosty weather across the county - so-called 'cat ice' forming in puddles. Cat ice is a thin sheet of ice from which the water underneath has receded, leaving it supported only at its edges. It is so named because it might support the weight of a light-footed cat, but no more.

Two unseasonably warm days are recorded at Pitsford - 21.8C on the 30th and 22.6C on the 31st, making these the warmest March days locally since 1968.
