Area Forecast Discussion National Weather Service Tucson AZ 350 AM MST Tue Feb 18 2020

SYNOPSIS. Dry conditions with above normal daytime temperatures through Thursday. A few showers may develop Friday, then scattered to numerous to prevail Friday night and Saturday as a weather system moves across the area. A chance of showers exists Saturday evening mainly east of Tucson, then dry conditions return Sunday into Monday.

DISCUSSION. Clear skies prevail across southeast Arizona early this morning along with light surface winds. Generally zonal flow aloft will continue across the area into Wednesday. This pattern will translate into sunny skies or a few cirriform clouds today, then increasing cirriform clouds from the south tonight into early Wednesday. Clouds are expected to decrease Wednesday afternoon followed by clear skies later Wednesday night.

Various 18/00Z models continue to depict upper ridge amplification over this forecast area Thursday ahead of a deepening low pressure system near the California coast. Flow aloft will become increasingly southwesterly Thursday night as the upper ridge axis moves east of the area, and low pressure aloft becomes centered west of southern California. The upshot is for dry conditions to continue Thursday into Thursday night, and most likely Friday morning as well.

Thereafter, a few showers should develop Friday afternoon especially east of a Safford-Sierra Vista line as the upper low approaches the southern California coast. The 18/00Z GFS/GEFS and ECMWF/ECENS were in fairly decent agreement regarding the expected precip potential starting Friday evening and continuing into Saturday as the upper low moves eastward into southern California by midday Saturday. As such, forecast confidence has increased regarding start/end timing of rainfall and high elevation mountain snow, as well as projected liquid amounts and snow accumulations associated with this system.

At any rate, the official forecast continues with isolated to scattered showers favoring locales east of Tucson Friday evening, then scattered to numerous showers across much of the area late Friday night into Saturday afternoon. The upper low is progged to fill while moving rapidly eastward into eastern New Mexico by daybreak Sunday. As such, isolated to scattered showers mostly east of Tucson Saturday evening followed by a return of dry conditions late Saturday night. Dry conditions will then prevail Sunday into Monday under northwesterly flow aloft.

The event total rainfall amounts are presently forecast to generally range up to around 0.30 inch in the valleys, and mainly from 0.10" to 0.50" across the mountains. However, liquid amounts approaching 0.80" may ultimately occur across the White Mountains. Event total snowfall amounts of 2-6 inches should be limited to above 8000 feet.

High temperatures this afternoon and Wednesday will range about 5-9 degrees above normal. Even warmer temperatures are on tap Thursday, and portions of the Tucson metro area may reach or exceed 80 degrees. A cooling trend will prevail Friday into Saturday followed by warmer temperatures returning especially next Monday.

AVIATION. Valid through 19/12Z. SKC-FEW clouds above 20k ft MSL into this afternoon becoming SCT-BKN clouds above 20k ft MSL later tonight and into Wednesday morning. Surface wind variable in direction under 12 kts. Aviation discussion not updated for TAF amendments.

FIRE WEATHER. Dry conditions with above normal daytime temperatures through Thursday. A few showers should develop Friday, especially during the afternoon hours, then scattered to numerous showers Friday night into Saturday. Expect isolated to scattered showers mainly east of Tucson Saturday evening, then dry conditions return Sunday into Monday. 20-foot winds will be terrain driven under 15 mph through Wednesday. Some gusty east to southeast winds should occur at times Thursday afternoon into Friday, then gusty southwest winds Saturday afternoon. Somewhat less wind to prevail Sunday into Monday, although occasional west to northwest afternoon gusts are forecast to occur.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
