Dramatic Increase in Cloudiness This Morning


Have just returned from walking along the Rillito Wash and can report that it's a warm morning, with gray dreary skies (see top image that shows the Catalinas from the U of A campus), here. Skies are covered with cirrus that's mostly old anvil debris from the abundant thunderstorms that occurred off to the northeast to the south yesterday afternoon and evening (see previous post). The increase in high level cloud cover has been very dramatic across Arizona, New Mexico and much of Mexico - compare the visible image this morning (lower graphic above) with the visible image from yesterday afternoon (previous post). One would think that it's a morning in late July (except for the low dewpoints), rather than the start of the first full week in June. A friend up in Show Low, Arizona, area reported yesterday afternoon (Sunday 6 June) that it was very hot for that elevation and that there had been several rumbles of thunder, but no rain at his place.
