A poor mans mid 1950s. I would be blown away if this actually continues in the heart of the summer though. We finally broke the curse on seeing major cold in January this year though so who knows.
Not sure it means anything... but the sky conditions in those pics matches the satellite around dawn. I don't think the first pic tells us anything because its so close up and only a small part of the sky is shown. Clouds could look blue at the time of day. Just my 2 cents.
