522 FXUS65 KFGZ 211620 AFDFGZ Area Forecast Discussion National Weather Service Flagstaff AZ 920 AM MST Sat Mar 21 2026 .SYNOPSIS...Summer-like high pressure will continue into next week, with temperatures reaching up to 25 degrees above normal. Please exercise appropriate precautions if you are planning on any outdoor activity. Breezy southwest winds and low humidity are also expected. && .DISCUSSION...The unprecedented March heat wave will continue into next week, though the hottest readings were likely achieved Thursday or Friday for most locations as the high pressure center will weaken a bit and slide southeast today and Sunday. The high may strengthen again and move back toward Arizona toward the middle of next week. Even with the slightly lower temperatures, daily record highs are currently forecast to be broken at Flagstaff each of the next 7 days, and each of these would break the old March record of 73 from 2007 - truly remarkable. It`s the same story for our other long-term observation sites including Winslow and Prescott. The other story as the high slides southeast today will be an increase in west-southwest winds to 15-25 mph - combining with low humidity of 5-10% to bring elevated fire weather conditions. Winds on Sunday are forecast to weaken slightly to 10-15 mph gusting near 20 mph. && .AVIATION...Saturday 21/18Z through Sunday 22/18Z...Look for VFR conditions.
