sunny skies late AM and early afternoon with sweeping opaque
high cloudiness attendant to approaching low amplitude shortwave.
Once the wave passes will see return to mainly clear skies by mid
afternoon through early evening. Did not make many changes to
highs given the anticipation of increasing solar insolation later
this afternoon, but will monitor for any changes with the delta
