A Snow Shower in May
Often in May, with the air still retaining some winter chill, and the land warming rapidly from near-summer sunshine, convective showers of snow and hail form over the Rockies and adorn the sky-scape. This happened over the weekend and I caught this image showing a beautifully picturesque shower as it was passing by to the east. The fibrous texture of the cloud’s top results from ice crystals formed as the shower cell bubbles skyward due to the heating below. Grayish snow and soft-hail can be seen falling out of the cloud obscuring the land surface underneath it. Surface temperatures were in the low 50s°F (12°C) in the sunshine, dropping to about 40°F (4°C) when one of these showers passed overhead. The snow and soft hail would whiten the ground, briefly providing a wintertime look to the May landscape and angering the nesting robins chilled by the sudden squall.
