Yosemite NP is closed for rest of week because of a large wildfire - photo above is of Half Dome in the smoke this morning (from Jack Hales webcam wall).
Map below shows high temperatures recorded yesterday - magenta indicates 100 F and higher! Note that TUS high was 112 F, and 113 shown on map is high from DM AFB.
Composite radar chart above is from 6:45 pm on July 24, with echoes about as predicted by WRF-GFS (see yesterday's post and CGs below).
Plot of detected CG flashes (below from Atmo and Vaisala) is for 24-hours ending at 5:00 am MST this morning - warm colors are from yesterday afternoon, while cool colors are from early morning yesterday.
Plot above is of GPS PW from campus for past seven days - the big drop in PW occurred on Sunday with values dropping from mid-40 mm to around 30 mm this week.
Interesting forecasts for this afternoon from the 06 UTC WRF-GFS run at Atmo. The composite radar forecast above is valid at 5:00 pm this afternoon, indicating strong storms over higher elevations of all of southeast corner of Arizona.
The two forecasts below of skew-Ts for this afternoon show why the model keeps the storms on the mountains. Just below is for TWC at 3:00 pm - the surface based BL reaches to 750 mb and has CAPE but no apparent way to release that CAPE with out a very strong outflow from east. But the elevated BL from 750 to 600 mb has CAPE that could produce storms over higher mountains. The forecast at bottom is for Mt. Graham valid at 1:00 pm and indicates that thunderstorms are probably about to develop there. Big difference in potential for storms today from high mountains into deserts.
