1015 - 1300hr DB / HC
S F2 increasing SW F3, 10.6degC rising, 45km, 8/8 strato / lenticular various, QNH 1002 steady.

This morning as expected rain stopped play at c0750 until 1000hr at Oxenhope. There were some heavy showers but nothing too prolonged.... mainly a none-event here but from the hills very heavy showers could be seen in various directions as the rain band continued to pass N and E , visibility was terrible, it then petered out and was totally fine but still heavily overcast for the rest of the morning and until 1300hr when it started to rain again, so we called it a day, for today.

Not much mipit movement noted over home first thing before the rain, but after 1030hr at Oxenhope Sentry, flocks of up to ten, threes, pairs and singles were noted on the move, all high up and going through in level flight like rockets on the very light tail wind. I diddnt book down any times as the flocks passed but it was obvious just by watching that movement was on an increasing trend as the morning progressed. In the last hour 85 were counted through, almost as many as we had noted in the first two hours. (Total count 187, not too bad for the back end of a wet morning here) As it was starting to rain gently again at 1300hr the passage was still continuing but had to get home for some lunch.

Also and most signicantly the normal northerly direction of mipit travel applicable to date through out the spring had today changed to all hard and desperate NW.

In addition to mipits Cormorants were on the move east, late morning and early afternoon. A skein of six were picked up coming high over Oxenhope radar, followed a little later by two singles and last by a four over Coombe Cross col. Three Swallows in singles were noted travelling fast north, two males and a female! all were moving low only feet from the ground, so some more distant ones may well have been missed. A female was noted on the wires back at the barn.
