Area Forecast Discussion
National Weather Service Tucson AZ
910 AM MST Wed Jan 18 2017

.SYNOPSIS...A series of storms will spread valley rain, mountain
snow and gusty winds over Arizona Thursday night into Saturday.
Snow levels will lower through that time potentially reaching the
valley floors east of Tucson by Saturday. After a break in the
weather another storm system is likely early next week.

&&

.DISCUSSION...Satellite imagery this morning showed low clouds
across northern Greenlee county, with clear conditions elsewhere.
Water vapor imagery and upper level plots this morning showed upper
low over northern New Mexico with trof axis extending SW into Sonora
MX. As this upper low/trof axis moves east today, short wave high
pressure will build into western AZ. This will provide dry NW flow
aloft over the area with highs today a few degrees below normal.

Above mentioned short wave ridge will pass through the area tonight
with cloud cover increasing late tonight out west and across the
area by noonish tomorrow. A few light valley rain/mountain snow
showers are possible north of Tucson tomorrow afternoon as a weak
wave pushes across the area.

The first in a series of weather systems moves across the area
Thursday night into Friday morning followed quickly by a second
storm, this one colder and wetter, Friday afternoon into Saturday
afternoon. Early look at 12z model data suggests that QPF/snowfall
amounts may need to be increased along with lowering the snow
levels. In any event, current winter storm watch out for the
mountains above 5500 feet looks OK. More on this in the afternon.

&&

.AVIATION...Valid through 19/12Z.
SCT clouds around 5k-9k ft AGL mainly E of KTUS. For tonight SCT-BKN
clouds mainly above 20k ft agl will then move from the west. Surface
winds will exhibit typical diurnal trends and generally be less than
10 kts. Aviation discussion not updated for TAF amendments.

&&

.FIRE WEATHER...Dry weather into early Thursday with generally
light winds and elevated humidity levels. Then a series of storms
will spread a good amount of precipitation across the area late
Thursday into Saturday with snow levels near 6000 feet Thursday
night and Friday dropping as low as 4000-5000 feet Saturday morning.
Gusty west to southwest winds are expected at times through this
period especially Friday night and across the mountains. Dry weather
returns Sunday before another storm affects the area Monday into
Tuesday.

&&

.TWC WATCHES/WARNINGS/ADVISORIES...
 Winter Storm Watch from Thursday evening through Saturday morning
  for AZZ510-511-514.

 Winter Storm Watch from Friday afternoon through Saturday morning
  for AZZ512-513.
