290 FXUS65 KFGZ 082055 AFDFGZ Area Forecast Discussion National Weather Service Flagstaff AZ 155 PM MST Sat Nov 8 2025 .SYNOPSIS...Dry and mild weather will continue through the rest of the weekend and much of next week. A more unsettled pattern with chances for precipitation may return by next weekend. && .DISCUSSION...A high amplitude ridge will gradually meander eastward over the next several days, likely peaking over our area Monday and Tuesday. This ridge will send daytime temperatures to 5-10, possibly even 15 degrees above normal for a few days. Deeper valley locations may not see as big of a response, due to inversions under the ridge. Toward the end of the week, the pattern begins to break down as a mean trough develops over the eastern Pacific. This trough will send s/wvs into the west from time to time, the first instance possibly being as early as this coming Friday. There is still quite a bit of uncertainty with the trough position after next weekend and into next week (outside our forecast period), but models seem to be be converging on the Friday/Saturday system. As of now, the s/wv moves into a fairly warm air mass and most precipitation should be rain. Later Friday night and Saturday, snow levels may descend to around 8000 feet, but still enough uncertainty that we cannot bank on this. For now, start thinking about unsettled and early winter-like weather for the end of next week. && .AVIATION...Saturday 08/18Z through Sunday 09/18Z...Expect VFR conditions, no precipitation expected but localized areas of FU/HZ possible from prescribed burns. Winds NE 10kts daytime, light and variable most places overnight, but KSEZ could see NE 15kts, gusts to 25kts due to amplified downsloping of NE winds.
