UPDATE. Updated Aviation Section
SYNOPSIS. High pressure will result in near to slightly above normal temperatures for the beginning of the weekend. Skies will remain mostly sunny with occasional increases in high clouds. A mostly dry weather system will arrive Sunday bringing cooler temperatures across the area with chilly morning low temperatures Monday and Tuesday. Temperatures will rebound slowly through the first half of next week.
DISCUSSION. Upper-level ridging continues to promote dry conditions across the Desert Southwest with only some passing cirrus to be noted on GOES West visible satellite imagery this afternoon. Mostly clear skies will continue through the remainder of this afternoon and through much of the day tomorrow.
Much of the day Saturday will be similar to today with mild temperatures remaining near to slightly above normal. Windy conditions are expected to develop across parts of southwest Imperial County tomorrow afternoon into Sunday so have issued a Wind Advisory. Increasing upper-level moisture ahead of a developing Pacific trough will promote an increase in upper-level cloud coverage late Saturday night. The trough axis will pass over the Four Corners area fairly quickly Sunday and move off to the east by Monday. The greatest moisture with this system will remain over northern Arizona with only a few showers possible across the higher terrain over southern Gila County. Cooler air moves in behind this system resulting in temperatures dropping into the low to mid 60s for highs across the lower deserts Sunday through Tuesday with Monday looking to be the coolest of those days. Overnight lows Monday night into Tuesday morning look to be chilly with low temperatures dipping down into the upper 30s to low 40s around the Phoenix metro.
Behind the aforementioned trough, a transient upper-level ridge will build into the southwest CONUS Tuesday into Wednesday before the next trough approaches the region later next week. GFS and ECMWF guidance differs on how deep this trough will dig. As of now, PoPs continue to remain low across south-central Arizona and southeast California with this system.
AVIATION. Updated at 2330Z.
South-Central Arizona including KPHX, KIWA, KSDL, and KDVT:
Passing high clouds at 20-25k feet are expected over the next 24 hours. Light easterly flow overnight will gradually veer to southerly during the late morning on Saturday, and eventually to westerly by Saturday afternoon. Winds should remain at or below 7 knots at all sites during this period.
Southeast California/Southwest Arizona including KIPL and KBLH:
Passing high clouds at 20-25k feet are expected over the next 24 hours, with a few clouds near 10k feet possible by Saturday afternoon. At KIPL winds will be light and variable overnight, but westerly winds will increase to 12-15 knots on Saturday afternoon. KBLH should remain light and variable until later Saturday afternoon but will also see westerly winds increase to 7-9 knots.
FIRE WEATHER. Sunday through Thursday: A weak low pressure system affects the region Sunday into Monday mainly ushering in cooler conditions. Moisture levels with the late weekend system should be rather dry, hindering precipitation chances although there is a chance of rain or high elevation snow on Sunday over high terrain east of Phoenix. Cooler conditions develop Sunday with highs falling below normal by Monday and into the lower 60s over the cooler lower deserts. Minimal warming returns returns Tuesday into Thursday as highs approach seasonal normal levels.Minimum humidity levels initially should stick around 25-35% much of the period, lowering into early next week with desert readings falling into the teens before humidity levels increase again later in the period. Breezy conditions move in for Sunday and Monday, mainly over deserts west of Phoenix. Light winds return again by Tuesday as weak high pressure aloft returns to the area.
SPOTTER INFORMATION STATEMENT. Spotters should follow standard reporting procedures.

I do not sell or share any user data or anything else for that matter. I do not keep site logs longer than I need to to keep bad actors off the site. Basically, I delete them after looking at them. If you are subject to CCPA, Google ads on this site will not be based on your past behavior so you will likely not see an ad for a lawn mower just because you looked for one at a big box website. I do not believe this site is subject to CCPA but I am doing what I can to follow the guidelines anyway.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
