Area Forecast Discussion National Weather Service Tucson AZ 827 PM MST Mon Dec 9 2019
UPDATE. Adjusted clouds, precipitation, fog, temps and dewpoints for the overnight hours.
SYNOPSIS. Skies will continue to gradually clear off this evening then some valley fog and patchy very low clouds will likely form by dawn and linger into the mid morning hours. Otherwise dry conditions are expected Tuesday into next weekend with a slow warming trend.
DISCUSSION. The primary dynamics associated with the upper low moving across SE AZ have moved off to the east and what we are left with is the cold pool aloft and without the sunshine to trigger the convection, it quickly died off this evening. Now we enter the gradual clearing out phase which will be difficult with the abundant low level moisture we have around and we will likely end up with some fog and/or patches of low stratus clouds. With the mid and high clouds quickly dissipating I opted to increase the fog to "Areas" from "Patchy" for the favored valley locations and left some clouds in the Gila valley near the NM border. The HRRR is suggesting LIFR conditions (fairly thick fog) in many of those valleys and it just 'feels like' a fog night for many areas. It will be interesting to see how this plays out overnight but be prepared for the potential for fog during your early morning travels.
At any rate, I removed the threat of showers from the forecast from here forward and tweaked with the clouds, winds, temps and dewpoints. The sunshine will return tomorrow and you should be safe to wash your car once the puddles disappear as we are not expecting rain at least into the weekend at this time.
AVIATION. Valid through 11/00Z. SCT to locally BKN clouds 3k-6k ft MSL through midnight then clouds thinning out. From 10/09Z thru 10/15Z areas of valley fog with VSBYS AOB 3SM and ISOLD-SCT stratus AOB 1k ft eastern valleys. KOLS and KDUG terminals potentially will be impacted. Becoming clear after 10/16Z. Winds diminishing to under 6kts by midnight. Aviation discussion not updated for TAF amendments.
FIRE WEATHER. Minimal fire weather concerns. Dry conditions return Tuesday and continue into the weekend. 20-ft winds will generally remain less than 15 mph through the forecast period.
PREV DISCUSSION. /issued 247 PM MST Mon Dec 9 2019/ The low over central to south-central Arizona continues to bring areas of valley rain and mountain snow showers with isolated embedded thunderstorms. This will continue through the late afternoon hours before ending from the west with partial clearing overnight as the low merges into the base of the broad trough downstream. Patchy fog possible in the early morning hours as things clear out. We'll probably have enough residual boundary layer moisture and patchy cloud cover to keep from reaching the cold potential of the airmass Tuesday morning, but still freezing in some colder valleys east and south of Tucson.
A dry zonal flow the rest of the week with a slow warm-up into the weekend. Another system could impact the region early next week, but the inland trajectory looks kind of dry for our neck of the woods. Primarily gusty winds and cooler temperatures by next Monday or Tuesday. Still seeing some signs of an active pattern the second half of the month with long range ensembles suggesting low height anomalies.

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.
