Hazy sunrise over the Catalinas at 6:00 am MST this morning. Down at bottom is a red sunset at Greymouth, New Zealand, half way around the world from here (note - Greymouth is on the northwest coast of the southern island - image from Jack Hales' webcam page).
The weather story graphic above, from TUS NWS, has an explanation of the summer solstice and indicates that astronomical summer begins at 8:32 pm this evening. However, the next few days promise a bit of cooling from this week's extreme heat. Clearly "real summer" began a number of weeks ago.
This morning's 500 mb chart (above) shows continued weakening of the anticyclone, which is centered over the New Mexico boot-heel. The morning sounding at TWC (below) indicates a sliver of CAPE - isolated showers and thunderstorms occurred from late yesterday into early morning hours over in Cochise County.
Forecast of precipitation for the coming week (below from 06 UTC WRF-GFS run at Atmo) indicates a bit of hope for light precipitation in our area. The GEFS plumes (below) focus the chances for showers at airport during the entire day on Wednesday the 23rd. Fingers crossed!
