Area Forecast Discussion National Weather Service Tucson AZ 251 PM MST Sat Dec 7 2019

SYNOPSIS. A Pacific weather system will bring increasing rainfall chances tonight followed by periods of valley rain and higher elevation mountain snow showers Sunday into Monday. Much cooler temperatures will also occur. Expect dry conditions with a warming trend next Tuesday into Friday.

DISCUSSION. Increasing clouds today with moisture streaming in from the west ahead of a Pacific storm system digging down the west coast. Precipitable water was around 3/4 of an inch on the morning sounding. It should peak just under 1 inch over the next 24 hours before slowly receding as the dry slot wrapping into the base of the low shifts overhead.

Shower chances increasing tonight, relying somewhat on orographics as the westerly flow increases. Generally lighter rainfall amounts in valleys overnight into Sunday. 1/2 to 2/3 of an inch in mountains as rain with snow levels still too high Sunday. As the storm system drops into Arizona Monday, snow levels will fall to around 8000 feet early Monday morning, to 7000 feet Monday afternoon behind the associated (weakening) frontal passage. Something like 2 to 5 inches of snow in the mountains above 7500 feet with 6 or 7 inches possible in one or two spots at highest mountain peaks above 8500-9000 feet.

Clearing from the west late Monday and Monday night. Decent cold air advection knocking temperatures back to well below average Monday. With the clearing Monday night, Tuesday morning should end up chilly with another hard freeze in colder eastern and southern valleys. A brief freeze possible in outlying areas around Tucson Metro and some foothills locations.

Dry with a warming trend the rest of the week, but a weakness in the flow will probably keep heights from supporting anything above average until around the end of the week.

AVIATION. Valid through 09/00Z. BKN-OVC cirrus clouds above 20k ft MSL today becoming SCT-BKN clouds 9k-13k ft MSL this evening into Sunday morning. ISOLD -SHRA developing west of KTUS this evening, then SCT -SHRA later tonight/Sunday. Winds SWLY to NWLY in the afternoon through the evening at mainly less than 10 kts. Becoming SLY overnight into Sunday Aviation discussion not updated for TAF amendments.

FIRE WEATHER. Minimal fire weather concerns. A weather system is expected to impact the area starting late tonight through Monday night with a chance of valley rain and mountain snow, particularly across the higher elevations. Dry conditions return Tuesday morning 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.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
