Area Forecast Discussion...UPDATED
National Weather Service Tucson AZ
849 PM MST Tue Nov 26 2019

.SYNOPSIS...A weather system will bring deep moisture and showers
spreading up from the south Wednesday afternoon and Wednesday night.
Areas of flooding possible southeast of Tucson. A strong Pacific
storm will bring significant valley rain and mountain snow later
Thursday into Friday. Windy conditions and much cooler temperatures
are also expected. Chilly overnight lows to end the week, with warmer
afternoon highs early next week.

&&

.DISCUSSION...Sent a quick update to tweak temps this evening and
POPS later Wednesday into Wednesday evening based on the latest
guidance. The adjustments were upward in nature for the afternoon
into the overnight hours, especially where we had significant QPF
forecast where I jumped the pops solidly into the categorical range.
The pop increase also included the Tucson metro area based on latest
deterministic and short range ensembles. If the trend of shifting the
back edge a bit further west continues, we may need to increase the
pops a bit more. There is likely to be a fairly sharp edge to the
precipitation on the west side Wednesday afternoon and placing that
is a bit tricky. No other tweaks made at this time.

&&

.AVIATION...Valid through 28/00Z.
FEW-SCT clouds at 8k-12k ft MSL, BKN-OVC clouds AOA 20k ft MSL.
Showers spreading in from the south Wednesday with SCT-BKN clouds 8k-
10k ft MSL, brief MVFR conditions possible south of KTUS. SFC wind
wly to nwly at 10-18 kts this afternoon, diminishing overnight. SE-S
winds 10 to 12 kts Aft 27/13Z. Aviation discussion not updated for
TAF amendments.

&&

.FIRE WEATHER...A good chance of valley rain will be possible from
Tucson south and east Wednesday afternoon, spreading across all of
southeast Arizona Wednesday night into Friday with significant snow
possible in the mountains. The precipitation will then come to an end
from west to east late Friday night into Saturday. Strong and gusty
winds will also occur late Thursday afternoon through Friday. High
winds possible in the mountains and some Cochise County valleys. Dry
and warmer conditions are expected Sunday into Tuesday of next week.

&&

.PREV DISCUSSION... /issued 319 PM MST Tue Nov 26 2019/
A busy pattern this week continues. Our first low has lifted into
the front range of the Rockies with the trailing cold front pushing
through our area earlier this morning. The front is washing out in
northern Mexico, with the HRRR showing higher dew points pushing back
in from the south as early as tonight.

A low off the coast of Baja is guiding much deeper moisture toward
our area over the next 36 hours, with showers spreading in from
the south tomorrow afternoon. Areas of heavy rain will bring some
flooding concerns late Wednesday into Thursday morning. Precip
amounts of 1 to 2 inches across southern Santa Cruz and the
southern half of Cochise county, with isolated higher amounts
possible. Snow levels should generally remain above mountain tops
with this first system.

The final piece of our weather puzzle this week will be a strong
and cold system digging down the west coast over the next 60
hours. Showers will increase in a strong upslope warm sector ahead
of the low late Thursday into Friday morning. Some clearing from
the west late Friday with a few snow showers hanging on in the
mountains Friday night. Snow levels will start to drift lower
Thursday evening, to around 8000 feet initially. A strong cold
front will push snow levels rapidly lower Friday morning,
bottoming out near 5000 feet Friday night. Our best moisture and
precip will correspond with snow levels near and above 7000 feet
just ahead of and with the FROPA. 1 to 2 feet of snow above 7000
feet with up to 3 feet near mountain peaks. Another round of
valley rain as this occurs, with possible flooding concerns in
some locations.

Strong winds also a concern, with windy conditions by Thursday
evening. High winds in the mountains (up to 50 or 60mph) handled
by the Winter Storm Watch, but we may need a High Wind Watch for
some lower elevations including Cochise County.

This system will push quickly into the central plains Saturday
with a dry westerly flow for most of the weekend. Chilly mornings
will remain, but a warming trend for daytime highs by Sunday.

We could see another system by the middle of next week.
