Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.

Area Forecast Discussion National Weather Service Tucson AZ 304 AM MST Thu Feb 27 2020
SYNOPSIS. Dry conditions will continue into Sunday with warmer than normal daytime temperatures. A weather system moving across the area will bring a chance of valley rain and mountain snow showers Sunday night through Monday night with a few snow showers possible Monday night across valley areas east and south of Tucson. Much cooler temperatures will also occur Monday followed by drier conditions and a warming trend by the middle of next week.
DISCUSSION. Warmer with less wind this afternoon thanks to a weakening pressure gradient. A few high clouds will grace the sky today. Friday into Saturday the warm temperatures will continue although high clouds will be more prevalent and thicker. Overall, winds will be relatively light Friday through Saturday.
The storm system the models have been advertising for quite some time is still on track and more recent deterministic runs have returned to the original scenario with the upper low moving across southern Arizona. While this system is not expected to be a heavy precipitation producer, the return to having the upper low over the area does result in a better chance of showers and also a colder system as it moves overhead. There has been some consolidation in timing with the main focus of precipitation occurring Monday although a threat of showers exists Sunday evening through Monday night.
I have made some adjustments with this forecast package based on the above idea. For Monday I pushed pops up further and dropped afternoon high temperatures another couple of degrees, pretty much mid 50s across the valleys. Forecast thickness values would suggest even a bit cooler is possible but a few peeks of sunshine would negate that.
For Tuesday night in this scenario, snow levels would drop below 4000 ft so the valley areas east and south of Tucson stand a chance of some scattered snow showers. Likely not much precipitation at that point but something that will need to be watched, especially if some showers end up being a bit heavier and dynamic cooling rears its ugly head.
Tuesday onward clouds and precipitation threat diminish rapidly in the deterministic runs vs the NBM and leaned toward the deterministic runs during that time frame. Temperatures will be gradually warming after Monday but are likely to remain below normal through Thursday.
AVIATION. Valid through 28/12Z. SKC or FEW clouds AOA 25k ft MSL this morning, with SCT-BKN clouds AOA 25k ft MSL this afternoon into Friday morning. SFC winds SELY to NELY mainly less than 12 kts thru the forecast period, though a few higher gusts may occur at KTUS and KSAD this morning. Aviation discussion not updated for TAF amendments.
FIRE WEATHER. Well above normal temperatures and daytime humidity values in the low to mid teens will persist through Saturday. Dry conditions are expected through Sunday afternoon. A storm system will bring isolated to scattered valley rain and mountain snow showers Sunday evening through Monday evening, with the best chances for precipitation occuring during the day Monday. Isolated showers may continue across the White Mountains Tuesday and Wednesday. Expect easterly 20-ft winds today and Friday at less than 15 mph. West winds should occur on Saturday, followed by gusty southwest winds of 15 to 25 mph on Sunday ahead of the next weather system. Elevated west to southwest winds should occur near the AZ/NM border next Monday and Tuesday.
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.
