Area Forecast Discussion National Weather Service Tucson AZ 258 AM MST Sat Jan 25 2020
SYNOPSIS. High pressure will bring warmer and dry conditions through the weekend. A pair of weather systems will push temperatures back down to average for late January most of next week, along with a few showers mainly near the mountains Monday and Wednesday.
DISCUSSION. Boundary layer moisture from the last system continues to stubbornly hang on, so patchy fog still not completely out of the question this morning. Latest mesoscale models show room for surface dew points to mix much lower this afternoon with less recovery in the evening.
A ridge building in from the west over the next 36 hours will dominate the weekend weather, bringing above average temperatures and drying. The ridge axis should be overhead Sunday morning.
The storm track will generally remain north of our area most of the coming week, but a couple of glancing blows will bring some cooling and a few showers mainly near the mountains. The first trough will push through the state Monday before a little cyclogenesis spins it up immediately downstream of us through eastern New Mexico and northern Texas. That may be a hint for the second system, but as for us, a few light showers near the eastern mountains along with 4 or 5 degrees of cooling and locally breezy conditions should cover it.
A shortwave ridge Tuesday in between systems, then a stronger system drops down through the Great Basin Wednesday and Thursday. It's a relatively dry trajectory, however ensembles have been dropping it in further west. With such an amplified ridge developing in the eastern Pacific, there could be enough room on the eastern flank to drop in right on top of us. This should be cooler and wetter than the first system, but still a little on the moisture starved side considering the inland trajectory and insufficient time to tap into any subtropical moisture. A better chance of showers, but still mainly near the mountains with QPF values below 1/10 of an inch for now. Still some room to boost that a little though.
The strong eastern Pacific ridge should dominate the rest of next week, with some suggestion of an unseasonably low latitude Rex block possible.
AVIATION. Valid through 26/12Z. SKC-SCT clouds around 25k ft MSL. Surface wind variable in direction under 12 kts except Saturday afternoon where winds are nwly. Aviation discussion not updated for TAF amendments.
FIRE WEATHER. Dry conditions. Expect isolated showers mainly across the White Mountains late Sunday night and Monday, and isolated showers east of Tucson Wednesday into Thursday. 20-foot winds will be terrain driven and mostly under 15 mph during much of the next 7 days. The exception is Monday when some gusty northwest afternoon winds are expected.
TWC WATCHES/WARNINGS/ADVISORIES. None.

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.
