Area forecast discussion, Aug 6, 4:10 PM MST, 3 hours 48 minutes before
Area Forecast Discussion National Weather Service Flagstaff AZ 410 PM MST SAT AUG 06 2016 .SYNOPSIS...Expect scattered showers and thunderstorms mainly from Flagstaff north and east today. Storms will become more isolated and located mainly near the New mexico border by Sunday and Monday. A surge in tropical moisture will bring active conditions back to the area by the middle of next week. && .DISCUSSION...Isolated to scattered convection developed today, with some cells exhibiting severe behavior. There has been a little more than expected activity to the west, where the drier air aloft is. Activity out east is a bit subdued right now, but may pick up soon. The airmass should continue to stabilize from west to east into Sunday and Monday as southwest flow continues. We expect that most activity will be near the New Mexico border by Sunday and Monday. By the middle of next week, model data continues to forecast a moisture surge by late Tuesday/Wednesday, associated with the passage of a tropical system near the Baja California peninsula. We have increased the chances for showers during the middle of the work week as a result. && .AVIATION...For the 00Z package...Expect isold-sct shra/tsra with single cell +tsra along and north of a line from KPRC-KINW-KSJN through 01Z-03Z. Skies should become nearly clear overnight. Activity more isold on Sunday, with coverage mainly east of a line from KPGA-KINW. Aviation discussion not updated for TAF amendments. && .FGZ WATCHES/WARNINGS/ADVISORIES...NONE. && PUBLIC...Peterson AVIATION...Peterson For Northern Arizona weather information visit weather.gov/flagstaff
