882 FXUS65 KFGZ 020512 AFDFGZ Area Forecast Discussion National Weather Service Flagstaff AZ 1012 PM MST Mon Jun 1 2026 .SYNOPSIS...Warm temperatures, mostly dry conditions, and mainly light southwesterly winds are expected this week. Chances for showers and thunderstorms increase by the middle of the week over southern Navajo and Apache counties. && .DISCUSSION...A building ridge will nudge itself into our area from as it remains centered over the southern Plains through much of this week. This will bring us warming temperatures and southwesterly breezes, with the heat likely peaking over the region Wednesday through Friday. Meanwhile, a weak upper low develops off of the California coast, dropping southward into Baja California over the next day or two. As the low pushes south, this will result in moisture being advected into the region, mainly across the White Mountains and nearby areas. Some showers and thunderstorms will be possible, mainly Wednesday and Thursday, across southern Apache and Navajo counties. By Friday, the low to our south pushes eastward, before moving into New Mexico/Texas. Weak ridging will arrive for Saturday with dry conditions returning. Beyond Saturday...the models have started to diverge from one another. There is the potential for another trough to push deep into southern California by early next week (keeps us dry and windy and slightly cooler) or we could end up under a strengthening ridge (keeps us warm with southwesterly breezes - also dry). With such a wide range, our confidence is low any particular solution at this time and what impacts that may bring for us in the high country. && .AVIATION...Tuesday 02/06Z through Wednesday 03/06Z...VFR conditions.
