664 FXUS65 KFGZ 242122 AFDFGZ Area Forecast Discussion National Weather Service Flagstaff AZ 222 PM MST Mon Nov 24 2025 .SYNOPSIS...Warmer and dry conditions return for today and will last through the week. There is potential for another storm system to impact the area over the holiday weekend. && .DISCUSSION...Today through Friday...After the unsettled weather of the previous week, we find ourselves in a period of quiet weather through the holiday. A dry northwest flow has set in aloft as a trough ejects to our east and we transition to a ridge. Dry air is already prevalent in the mid- to upper-levels, but decent surface humidity still lingers. Areas of dense fog were prevalent across northern AZ this morning, and local patchy fog will still be possible tonight through tomorrow morning. Ridging will continue to build through mid-week, and temperatures will climb a little each day. By Thursday we see daytime highs 5-10 degrees above normal for the majority of our forecast area. Along with light winds, pleasant weather is anticipated for Thanksgiving. The amplitude of the ridge declines a bit by Friday as a weak shortwave moves through and puts a halt on the warming temperatures. Saturday and beyond...Extended guidance shows potential for another unsettled period this weekend into next week, but there still remains high model spread on how the 500mb pattern will evolve. Some ensemble members (particularly ENS members) favor a scenario where ridging remains stronger along the west coast, and we get a more dry northwesterly flow. Other members favor a scenario where the ridge breaks down and a deep low dives in to bring rain and snow. At this time, there is a potential for weather impactful to weekend travel. Continue to monitor the forecast in the upcoming days if you have travel plans. && .AVIATION...Monday 24/18Z through Tuesday 25/18Z...Mainly VFR. Patchy MVFR/IFR/LIFR in low CIGs and BR/FG until 20Z.
