Convective cloud starting to disperse as stratocumulus layer above increases - appears to be lowering too. Some farily thick cirrus visible through chinks in the stratocumulus. Excellent visibility. Surface wind has backed and eased somewhat.

Bright at first, but increasingly cloudy over the past hour. A bit of drizzle blowing about in the breeze. Stratus visible in the southern half of the sky, and visibility much reduced to the south and southwest - it is still very good to the north and northeast. A chilly-feeling day after the recent warmth, with a maximum temperature today of 12.3 (1438z), which is just below average for mid-late April.
