Synopsis – TUE AUG 19 2025

High pressure anchors closer to 4-corners late week into the weekend. This action brings on a warming trend and a surge of Monsoonal moisture to our area. As that moisture spreads through by Friday, expect t-storms to increase, favorning dry lightning and possible periods of isolated heavy rain. Even Death Valley should see t-storm action by the weekend…DMATT
