Area Forecast Discussion National Weather Service Tucson AZ 428 AM MST Fri Jan 17 2020
SYNOPSIS. Dry conditions to prevail today into early next week. Temperatures will also be warming, with highs in the 70s for the lower deserts and generally 60s south and east of Tucson. A slight chance of showers will return Tuesday and Wednesday as a weak storm system brushes the region. This will also usher in slightly cooler temperatures.
UPDATE. Based on satellite imagery and observations, fog has become dense across portions of the Upper Gila River Valley and south into the San Simon Valley. Other areas of dense fog likely exist from Mammoth to Kearny, therefore decided to issue a Dense Fog Advisory to cover the morning commute across these areas. The advisory runs until 16Z.
DISCUSSION. issued 320 AM MST Fri Jan 17 2020/Our Thursday weather maker is sliding into the central U.S. and skies are clearing in its wake. With clearing skies and yesterday's rain, fog has developed and is currently located in the San Pedro River Valley from Mammoth to the confluence with the Gila River Valley. There are also other areas with fog development and this should continue through roughly 15Z this morning. There could be some isolated areas of dense fog near Safford, San Carlos, Bisbee, and Mammoth to Kearny, however it does not seem widespread enough for any products at this time.
As we head into the weekend, expect a nice warmup with daytime highs in the 70s for the lower deserts from Tucson west and 60s in the higher valleys south and east of Tucson. Sunday and Monday look to be the warmest, however there will be some high clouds around which may limit the full potential.
Once the ridge quickly progresses east of the area Monday into Tuesday, multiple shortwaves will then progress through muddled flow. The first two shortwaves will move through the region Tuesday and Wednesday. The third shortwave is forecast to pass through the region generally Friday. With each passing shortwave, cloudiness and light valley rain showers and high elevation mountain snow showers will be possible. At this time, precipitation potential favors areas east of Tucson. There is considerable differences in timing and southern extent of the shortwaves, but confidence of an unsettled pattern is high. Due to the cloudiness and isolated showers passing through the region, daytime temperatures will cool back into the 60s for the lower deserts and 50s south and east of Tucson Wednesday and beyond.
AVIATION. Valid through 18/12Z. Cloud decks near the AZ/NM border 8k-12k ft MSL clearing from west to east this morning. Areas of fog valleys mainly east of Tucson with periods of MVFR or IFR CIGS/VSBYS possible mainly KSAD/KDUG. Fog generally clearing by 17/16z. Then, generally SKC conditions through the remainder of the period except for a FEW passing clouds AOA 20k ft MSL this afternoon. Surface wind variable in direction less than 10 kts into Saturday morning. Aviation discussion not updated for TAF amendments.
FIRE WEATHER. Dry conditions will prevail into Monday. A slight chance of showers returns to areas near the New Mexico border and across the White Mountains Monday night through Tuesday, and again Wednesday into Wednesday evening. Elevated easterly 20-ft winds Sunday and Monday with some gusts to 25 mph. Westerly winds approaching 15 to 20 mph mainly east of Tucson on Wednesday. Otherwise, 20-ft winds terrain driven less than 15 mph.
TWC WATCHES/WARNINGS/ADVISORIES. Dense Fog Advisory until 9 AM MST this morning for AZZ506-508- 509.

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.
