NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
810 PM MST Thursday Apr 17 2014 


Synopsis... 
a Pacific storm will move into the area starting tonight bringing 
increasing moisture and clouds. By Friday afternoon this system will 
support slight chances for showers from the Colorado River east 
across south central Arizona and into the higher terrain. Daytime 
temperatures for Friday and Saturday will fall to more seasonal 
values. After the storm and clouds move to the east on 
Sunday...temperatures quickly warm back into the 90s for early next 
week with mostly sunny skies. 


&& 


Discussion... 
considerable high clouds were beginning to stream into the region 
from the west this evening...associated with the approaching Pacific 
trough. Models continue to move this system into Arizona late Friday 
Friday through Saturday night and is a concern. A system as 
dynamical as this...moving over a very warm afternoon boundary layer 
always has potential for great instability...including thunderstorms 
if moisture is available. Even only middle level moisture over a very 
dry boundary layer could generate high based showers/storms 
resulting in strong downburst winds and areas of blowing dust on the 
deserts. 


After reviewing this evenings coastal weather balloon soundings 
this system was still too far west to measure any appreciable 
moisture. However...upper level streamlines drawn from 00z vapor 
imagery loops show highly difluent flow aloft just off the Southern 
California/northern Baja California coasts...indicating increasing vertical motion. And 
under this difluent field...offshore precipitation water amounts continued 
to grow with every passing hour...I.E. A large field of 0.75 to 0.90 
inches with expanding areas of 1.05 inches. 


Supposing an increased moisture field with a dynamical system... 
including warm desert temperatures...an argument can be made for 
expanding a shower/thunderstorm threat over a large area southwest and south 
central Arizona. Updated forecasts...including a hazardous weather 
outlook...were sent earlier to reflect this. 


On Saturday the upper level cold pool with considerable middle level 
moisture circulating around the low center should continue a threat 
for showers and thunderstorms into Saturday evening. 


Previous discussion...213 PM MST... 
as the low approaches the Desert Southwest tonight...expect clouds 
to thicken from the southwest to the northeast late tonight into 
Friday morning. Skies will likely become mostly cloudy and possibly 
cloudy at times during much of the daytime hours Friday. Models show 
weak to moderate difluence aloft and sufficient Omega in a near 
saturated 600-400mb layer starting Friday morning. Am expecting some 
high based...12-15k feet...showers to develop sometime Friday 
morning into early Friday afternoon...especially along and just 
behind the leading edge of the middle level moisture plume. Since the 
sub-cloud layer will be dry...not quite Bone dry...not expecting too 
many locations to see rain hitting the ground...mainly higher 
terrain locales. 


Chances increase Friday afternoon and early Friday evening...but 
overall coverage will be limited and probability of precipitation still only in the slight 
chance category and mainly covering the higher terrain. The warm and 
dry sub-cloud layers may bring the potential for gusty winds and 
outflows if a storm gets organized enough. The main upper low 
circulation will hang back across southeast California Friday 
afternoon...then slowly progressing into central Arizona during the 
day Saturday. Slight chance probability of precipitation will remain through Friday night 
into Saturday evening across south-central Arizona with chance probability of precipitation 
across the higher terrain in Gila County. Quantitative precipitation forecast amounts for the entire 
event will be near zero across the lower deserts to around a tenth 
of an inch across Gila County. 


Dry westerly flow transitions into the area Sunday...quickly warming 
temperatures back into the 90s for early next week. Broad area of 
Pacific troughing still prognosticated to sweep into the west late Monday 
into Tuesday...although latest model runs vary in their depth and 
strength as it moves in from the northeast Pacific. The set-up still 
looks promising for a return to cooler (and more seasonal) 
temperatures by middle part of next week...but any chances for rain 
look pretty remote. Maintained some influence of climatology in the 
pop grids given the presence of troughing...but unless the models 
expand the southern extent of the system...even those single digit 
values may be overdone. 


&& 


Aviation... 
south-central Arizona including kphx...kiwa...and ksdl... 


Through 17z Friday...broken clouds at or above 25 thousand mean sea level. Light wind under 9 
knots. From 17z Friday to 23z Friday...thickening and lowering clouds 
becoming broken 10 thousand above ground level by 19z. An increasing chance of showers and 
isolated thunderstorms. Increasing southwest wind 5 to 15 knots... 
but gusty and erratic near thunderstorm downbursts. 


Southeast California and southwest Arizona including kipl and kblh... 
through 16z Friday...broken clouds at or above 25 thousand mean sea level. Light south wind 5 to 10 
knots. From 16z Friday to 23z Friday...thickening and lowering clouds 
becoming broken 12 thousand above ground level by 18z. A slight chance of showers and 
isolated thunderstorms. Increasing south to southwest wind 5 to 15 
knots...however becoming erratic and gusty near thunderstorm downbursts. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Sunday through Thursday... 
westerly flow will bring a warming and drying trend to the region 
through Tuesday. Thereafter...a cooling trend is expected as an area 
of low pressure moves through the western states. The biggest impact 
with this system will be an increase in wind...particularly on 
Wednesday. Low rhs during the midweek period will also present an 
increased fire danger threat. 


&& 


Psr watches/warnings/advisories... 


Arizona...none. 


California...none.
