A bright start to the weekend with frequent sunny intervals (6/8) and a freshening breeze from the SW.

(10:53), 10.3°C, RH 74%, DP 5.8°C. 1013 hPa (F), Wind 12 mph SW.

Yesterday (17th)
Min = 8.4°C
Max = 12.2°C
Rain 0.0 mm
Sunshine = 2.7 hours.

February mean temperature climbing quickly back up, now at 4.3°C. If the forecasts turn out to be correct, this month could end up like December & January, i.e., above normal and that would make this winter overall, warm, dry and reasonably sunny.

Heavy rain last hour.

Cold front passed over at around 15:00 with the wind direction swinging round from SSW to NW and deposited all of 1.4 mm of rain, and the maximum gust was 25 mph.

Temperature slowly dropped during the rain from a max of 11.2°C, down to 9.8°C just prior to the CF, then it abruptly dropped around 2 degrees to 7.7°C as the front passed through.

The day now ends as it started, with light wind and sunshine, but a little colder.

(17:00), 7.8°C, RH 76%, 3.8°C, 1012 hPa (R), Wind 3 mph NW.

... cold front through here (West Moors/East Dorset, not far from Hurn) ~1545Z, with short burst heavy rain, then dropping back to light/intermittent by 1555Z, PPN ceased ~1615Z. Total rain = 1.3 mm, which brings the monthly total up to 19 mm, representing around a third of the 1971-2000 long term average: this follows a reasonably dry January (55%), and unless rectified by the end of the month, would mean that we've had the 6th month in a row with below-average rainfall - though those last year were not dramatically below normal.

Cb calvus tops illuminated by the setting/set sun until at least 1805Z. Temperature dipping sharply ... currently (1815Z) 5.5°C, from a day maximum of 11.1°C.

Martin.
