NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Tucson Arizona 
215 am MST Thursday Dec 18 2014 


Synopsis...the final weather system in this latest series will move 
across the region today with another round of showers developing 
later this morning and continuing into the afternoon. The showers 
will end this evening with areas of fog developing for Friday 
morning. Dry conditions are then expected into the middle of next 
week with temperatures gradually warming to slightly above normal 
levels by Wednesday. 


&& 


Discussion...just a few isolated showers around this hour with 
some fog developing here and there. This will change as the morning 
progresses...especially after sunrise. Final shortwave currently 
rotating around the bottom of the longwave trough will move across 
the region through the day resulting in precipitation blossoming 
over the central part of the County Warning Area later this morning then expanding 
as it moves off to the east through the afternoon. Around middle 
afternoon expect showers to be occurring from the Tucson area 
eastward with snow falling above about 6500-7000 feet. By 
sunset...showers will be confined to Cochise...Graham and Greenlee 
counties as it pushes east and ending all areas by/around midnight. 


I raised the quantitative precipitation forecast a bit from what was in the grids earlier with the 
focus south and east of Tucson for a general 0.10-0.30 over the 
valley areas and and 0.25-0.50 over the mountains. For snowfall...I 
would expect an additional 2-4 inches over most of the mountain 
areas with local accumulations pushing 6 inches today into the 
evening. 


After the precipitation ends later tonight the skies will begin to 
clear out which after 48 hours of wetness...should allow for areas 
of fog to form late tonight into Friday morning so I tweaked the 
grids from patchy valley fog to areas of valley fog. Potential for 
some locally dense fog in the favored colder valleys east of Tucson 
so tossed in patchy dense fog amongst the areas of fog. With the 
fog and cold air mass still in place Friday will have below normal 
high temperatures for another day. 


Then Saturday a rather weak shortwave will drop southeast across the area 
but this feature should only produce a few middle and high clouds as it 
passes. However...this will transition the flow aloft to northwest from 
Sunday through Wednesday with heights rising resulting in mostly 
clear skies and warming temperatures reaching a few degrees warmer 
than normal by Tuesday and Wednesday. 


Beyond that...long range models beginning to advertise the potential 
for another decent trough to move through or nearby the area next 
Thursday and/or Friday for another chance of precipitation.

Aviation...valid through 19/12z. 
Isolated to scattered valley Rain/Mountain snow showers will occur 
mainly east of ktus through mid-morning. Scattered to numerous valley 
Rain/Mountain snow showers will then develop around 15z-17z today 
and continue into this afternoon. Areas of MVFR conditions will 
occur especially across the higher terrain and with heavier precipitation. 
Thereafter...valley Rain/Mountain snow will decrease from west to 
east this evening followed by dry conditions late tonight into early 
Friday morning. Cloud decks today will generally range from 3-6k feet 
above ground level...though bases less than 1k feet above ground level will occur. Expect occasional 
visibilities reduced to less than 1sm in fog through this afternoon. Gradual 
clearing will occur this evening into early Friday morning. Surface 
wind will mostly be less than 10 kts. Aviation discussion not 
updated for taf amendments. Francis 


&& 


Fire weather...unsettled weather will continue today in the form of 
valley rain and mountain snow. Snow levels will be as low as 6000 feet 
with several inches of snow accumulations above 7000 feet. The 
valley rain and mountain snow will decrease from west to east this 
evening...then dry conditions will prevail late tonight through next 
Wednesday. Expect generally light terrain driven winds during much 
of the period into the middle of next week. However...some northwest 
breezes may occur Monday afternoon across the upper Gila River 
valley including Safford. Daytime temperatures will be well below 
normal today followed by a gradual warming trend Friday into the 
middle of next week. Francis
