NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
355 am MST Sat Aug 23 2014 


Synopsis... 
dry conditions along with a warming trend can be expected this 
weekend...though temperatures will remain slightly cooler than 
Norma. Storm chances return Monday through Wednesday as deep 
moisture returns to the region. A drying trend is anticipated late 
next week. 


&& 


Discussion... 
today and Sunday... 
satellite imagery shows troughing over much of the western Continental U.S. 
With Tropical Storm Lowell far off the Baja California coast. The upper low 
that influenced our weather in recent days has weakened and shifted 
onto the High Plains. Drier and warmer air aloft has spread in 
behind it over our area. This will keep storm chances outside of our 
forecast area this weekend except for a very slight chance over 
portions of southern Gila County on Sunday. Temperatures will be on 
the increase but still be below normal today and probably a bit 
below normal Sunday as troughing lingers over the interior west. 


Monday through Friday... 
models are in pretty good agreement with a moistening trend Monday 
and Tuesday as ridging to the east tries to expand westward...for 
more southeasterly flow aloft over northwest Mexico...and Tropical 
Storm Marie tracks northwestward off the coast of Mexico. Models 
remain in good agreement keeping Marie well offshore. They also hint 
at an inverted trough over Sonora trying to move into southern 
Arizona before weakening...NAM more distinct with the feature than 
GFS and European model (ecmwf). Model solutions for quantitative precipitation forecast over our area align best late 
Monday night and Tuesday over south-central Arizona. This appears to 
be associated with a short wave passing through on the southern end 
of a renewed western states trough...interacting with a moistened 
airmass. Made some upward adjustments to the probability of precipitation over south-central 
Arizona...most noticeably between 06z-18z Tuesday...but the numbers 
are still conservative. GFS and European model (ecmwf) begin differing in their 
solutions on the flow pattern Tuesday with quite noticeable 
differences by Wednesday. The differences are not in how they handle 
the track of T.S. Marie but rather the troughing over the western 
Continental U.S....and the influences of the ridging to the east and west. In 
short the European model (ecmwf) has deeper troughing and is slower to shift it 
eastward than the GFS. Thus...the European model (ecmwf) brings in drier air and 
keeps our forecast area dry after Wednesday. The European model (ecmwf) ensemble mean 
provides some support to the operational run. In fact...the gefs 
mean also supports the European model (ecmwf) by indicating lingering troughing. Made 
some subtle adjustments leaning toward the European model (ecmwf) dropping probability of precipitation from 
the low deserts beginning Thursday. High temperatures decline early in the 
workweek with increased humidities and clouds then slowly rebound. 


&& 


Aviation... 
south-central and southwest Arizona and southeast California 
including kphx...kiwa...ksdl...kipl...and kblh... 


Aside from a few high clouds...skies should remain mostly clear 
through at least middle day Sunday. No storms are expected at any of 
the terminals this weekend. Winds will be light and will favor 
typical diurnal patterns. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Monday through Friday... 
moisture will return to the area Monday evening and as a 
result...the chances of showers and thunderstorms will increase 
early next week. There are some model differences from Wednesday 
Onward regarding how much moisture will remain in place during the 
week. GFS suggests elevated humidities right through Friday whereas 
the European begins drying things out middle week. Maintained elevated 
values through the end of the week until better model consensus can 
be obtained. Overnight recoveries this week are expected to be good 
with relative humidities only dropping into the 20-30 percent range 
each afternoon.

Psr watches/warnings/advisories...
