10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

Area Forecast Discussion National Weather Service Tucson AZ 230 PM MST Fri Dec 6 2019
SYNOPSIS. Dry conditions with warmer than normal daytime temperatures into Saturday. Another weather system will bring valley rain and high elevation snow Sunday into Monday. Dry conditions with seasonable temperatures will prevail next Tuesday into Friday.
DISCUSSION. Shortwave ridge overhead today resulting in warmer high temperatures versus yesterday, under partly cloudy conditions. The mid-level deck that moved over eastern Pima county this afternoon did have some virga.
Satellite imagery this afternoon showed a large upper level low off Oregon/northern California coast with lots of mid-high level clouds extending from southern California/northern Baja southwest extending southwest to 25N/125W. Under this cloud deck are PW values over 1". Thus higher PW values will gradually overspread the area this weekend. Models pretty consistent on bringing a chance of showers, as early as Saturday evening, but mainly overnight in Sunday morning NW of a Arivaca to Clifton line. As the upper level trof approaches the area Sunday there will be scattered to numerous showers which will continue into Sunday night, although can see a break out west of Tucson. Latest model runs are now showing that the tail end of this upper level trof will close off briefly on Monday. Models also are coming in slower versus previous runs. Increased PoPs late Sunday night into Monday across most of the area. As cold pool aloft comes through on Monday can see a few thunderstorms, but at this time the chances are low thus left them out of the forecast. Later shifts will be evaluating the chances for thunder.
Storm total QPF was heavily weighted toward WPC guidance which is in line with ensemble guidance from ECWMF/CMC/GFS. The NBM was not considered as it was woefully light on QPF. Valley totals from 0.10" to 0.50" with 0.50" to 1.25" in the mountains. Could see isolated totals of 1.50" to 2" at the highest mountain elevations.
Snow amounts, as usual, will be tricky. Snow levels for most of the mountain ranges will remain above the tips through Sunday evening. The exception will be across the Whites where snow will start to accumulate Sunday. Snow levels falling between 7000 and 7500 feet on Monday. At this time going with snow amounts above 7000 feet in the 3 to 7 inch range with localized amounts up to 10" at the highest elevations. These totals will likely change over the next 24-48 hours.
Lingering showers eastern sections late Monday into early Tuesday otherwise drier weather settles in Tuesday through the end of next week. An upper level trof moves across the area on Wednesday but it will be dry for the area.
Temperatures will remain above normal Saturday then be at or slightly below normal Sunday through Tuesday then turning slightly warmer the rest of next week.
AVIATION. Valid through 08/00Z. SCT-BKN cirrus clouds above 20k ft MSL persisting through the forecast period. FEW-SCT clouds increasing 10-15k ft MSL Saturday afternoon. SFC wind generally ELY/SELY less than 10 kts this afternoon. Winds will then be light and variable overnight into Saturday morning, becoming SWLY to NWLY in the afternoon at mainly less than 10 kts. Aviation discussion not updated for TAF amendments.
FIRE WEATHER. Minimal fire weather concerns. Dry conditions through Saturday. A weather system is expected to impact the area starting late Saturday night through Monday night with a chance of valley rain and mountain snow. The best chance for precipitation will be from central Pima County eastward and northward, and particularly across the higher elevations. Dry conditions return Tuesday afternoon and continue through the end of the work week. 20-ft winds will generally remain less than 15 mph through the forecast period.
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. |
