Area Forecast Discussion National Weather Service Tucson AZ 335 AM MST Thu Dec 12 2019
SYNOPSIS. Dry conditions and a warming trend will prevail through Saturday. A weather system moving north of the area may bring isolated showers to the White Mountains Sunday into Sunday evening. Behind the departing system, expect dry conditions but cooler temperatures early next week. Slightly warmer temperatures will return next Tuesday and Wednesday.
DISCUSSION. High pressure aloft was centered west of northern Baja California near 25N/135W with a ridge axis extending eastward to the Baja California Spur early this morning. The upper high will expand northeastward briefly into the southwestern CONUS by midday Friday. Some cirriform clouds should across the area today, but clear skies to prevail tonight and Friday with perhaps just a few thin cirrus at times.
A fairly fast zonal flow aloft regime will occur Saturday ahead of a shortwave trough moving southeastward toward the Pacific Northwest. The shortwave trough is progged via various 12/00Z models to move southeastward toward the Four Corners region Sunday. Expect dry conditions to continue Saturday ahead of this approaching system. Isolated to perhaps scattered rain and snow showers are forecast to occur Sunday into Sunday evening across the White Mountains. Liquid amounts will be quite light, with just a few hundredths of an inch likely confined to the highest peaks. Some westerly to northwesterly breezes may also occur Sunday afternoon especially east of Tucson.
Dry conditions will occur areawide late Sunday night into Monday as northwesterly flow aloft prevails in response to high pressure aloft building near the West Coast. The GFS/GEFS and ECMWF/ECENS were fairly similar with depicting an upper ridge to extend from southern California northward into the Pacific Northwest on Tuesday. The flow aloft next Wednesday should become southwesterly as the upper ridge moves east of the area, and an upper trough deepens west of the southern California/northern Baja California coasts. This pattern will maintain precip-free conditions across southeast Arizona next Tuesday into Wednesday. However, some locally gusty easterly winds may occur at times Tuesday into Wednesday in response to a somewhat tight surface pressure gradient.
Although beyond the scope of this forecast package, the potential exists for at least a slight chance showers and high elevation snow showers perhaps as early as Thursday as per the GFS, and as late as Friday as per the ECMWF. The GFS/GEFS and ECMWF/ECENS suggest that the bulk of heavier precip would favor locales southeast to south of the area. Given the time period mentioned (Days 8-9), uncertainty is quite high as of this writing regarding timing and potential liquid amounts and snow accumulations.
At any rate, high temperatures this afternoon will be quite similar to temps achieved Wednesday from Tucson westward, but will be several degrees warmer versus Wednesday across eastern sections. Expect 3-7 degrees of warming Friday followed by no significant change in high temps Saturday. A cooling trend is on tap Sunday into Monday. Although morning lows Monday and Tuesday will also be cooler versus weekend morning lows, these forecast temps will only be generally just a few degrees below seasonal normals. After the chillier feeling early Tuesday morning low temps, a very modest warming trend should prevail Tuesday into Wednesday.
AVIATION. Valid through 13/12Z. Clear skies early this morning becoming few to broken clouds above 25k ft MSL late this morning and this afternoon. Decreasing clouds this evening with mainly SKC conditions by end of period. Surface wind variable in direction under 12 kts. Aviation discussion not updated for TAF amendments.
FIRE WEATHER. Dry conditions with a warming trend through Saturday. A weather system moving across the Four Corners region will some breeziness Sunday, and may produce isolated rain and snow showers across the White Mountains. Dry conditions areawide early next week but with cooler temperatures. Locally gusty east winds may occur Tuesday into early Wednesday of next week.
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. |
