198 FXUS65 KFGZ 021739 AFDFGZ Area Forecast Discussion National Weather Service Flagstaff AZ 1039 AM MST Sat Aug 2 2025 .SYNOPSIS...Hot and dry conditions will continue through early next week. Moisture may return around the middle of next week. && .DISCUSSION...High pressure continues to remains across the Desert Southwest this morning and will stay in place through the weekend. This pattern keeps us dry through the weekend with hot temperatures expected. The high starts to shift to the east early in the new week, which may allow for some moisture to return towards the middle of the week. With high pressure continuing to sit over the region, we will continue to see things drying out. Moisture is meager and any showers that develop will be limited to Apache County today. With little to no moisture pushing into the region (outside of the White Mountains), RH values dropping into the single digits to lower teens and afternoon breezes, it will keep near-critical fire weather concerns through at least early next week. With no relief in sight, the heat will continue across the forecast area. Depending on whether or not we can get some moisture into the area by midweek, the current warning for the Grand Canyon may need to be extended further. The high looks to push to the east and over New Mexico early in the week, with the potential for some moisture to advect back into our area. Whether or not we will be able to see much develop is yet to be seen and forecast confidence is currently low. Another issue will be the heat combined with increasing moisture and we may see some of the hottest conditions of the summer, especially across the lower elevations of Yavapai County. The heat looks to peak around Wednesday or Thursday and we may need to raise some headlines. However, if we can get decent moisture into the region we may see more cloud cover and in turn could see some lower temperatures. && .AVIATION...Saturday 02/18Z through Sunday 03/18Z...Expect mainly VFR conditions.
