Synopsis – FRI AUG 22 2025

For those of you waiting for our T-storm season, wait no longer. Our area is currently under a Southerly flow, with a strong ridge centered over 4-corners. This is a classic setup for Monsoon moisture. That moisture (particularly over higher terrain) should make its way into our area by Friday and last into the weekend thru most of next week. Temps will also drop as next week progresses, so Bishop is looking at 87 degrees as a high by next Wednesday…DMATT
