Looks like September will close out with two near misses and a big rain from an early morning MCS. View above is from 7:05 am MST this morning - Monday, September 29th. crisp clear skies except over the Catalinas where some clouds are still hanging on the mountain tops. Yesterday 6 ALERT stations in and near the Catalinas had light rainfall amounts. Looks like mostly northwesterly flow for the coming week - below is GFS ensemble mean 500 mb pattern valid on October 6th..
Jack Diebolt sent some interesting satellite images from early Saturday afternoon. Above is visible image of the north end of the GoC - radar echoes are superposed and show line of storms extending south almost to the ocean. Large, darker area to the right is the El Pinacate volcanic area. Image below shows the same area after the storms and clouds had moved a bit to the northeast. Of interest are the dark areas of sand now apparent to the west of El Pinacate. These are apparently due to wet sand having a slightly different albedo, after the rains that fell there. The wet sand areas were also apparent on some IR images, due to evaporation cooling the sands where the rain fell. The wet sand streaks apparently extend northward to the vicinity of I-8.
