April 22 [Day 63] (Valley View site) The temperature reached a high of 19C at 1200 from a low of 4.5C and was 14C at 1600 but fell rapidly to 8C at 1700 as a disturbance brought steady rain that started at 1645. Ground winds were variable and generally light only occasionally gusting to 15 km/h and ridge winds became light SSW after 1300. Cloud cover was 10-60% cirrus and altocumulus until noon after which cumulus and stratocumulus cloud moved from the SW and thickened to 100% after 1400. Raptor migration was very sparse with only 6 birds moving, 3 of which were seen between 1152 and 1155, and the last bird of the day, a Red-tailed Hawk, moved north at 1626 shortly before the rain started. No new bird species were recorded but a single Brown Elfin was a new butterfly species for the season. 10.25 (731.5) SSHA 2 (36), COHA 1 (8), RTHA 2 (85), MERL 1 (9) TOTAL 6 (2736)
