NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
1025 PM MST Monday Sep 1 2014 


Update...updated aviation discussion. 


&& 


Synopsis... 
above normal temperatures will continue through the majority of the 
week under mostly dry conditions. Moisture will make a gradual 
return into the region during the late week...supporting increasing 
chances for afternoon and evening thunderstorms over the higher 
terrain of eastern Arizona. By the weekend...a deeper tropical moisture 
profile may begin to work into the region bringing increasing 
humidities and cloud cover with slight storm chances back in the 
forecast over the Lower Desert elevations of Arizona and towards the 
lower Colorado River valley. 


&& 


Discussion... 
light...and deep westerly flow across the region along with high 
pressure aloft is keeping skies clear and temperatures above normal 
across our County Warning Area this evening...with Phoenix Sky Harbor reporting a 
high of 108 today. The latest NAM continues to show little change in 
the sensible weather through mid-week...with mainly clear skies and 
above normal temperatures to continue through the period. As far as 
the very short term is concerned...other than some very minor 
adjustments to the temperature and dewpoint grids...inherited 
gridded and zone forecast products are holding up quite well...and 
no updates are planned. 


&& 


Previous discussion... 
clear skies prevail across the Desert Southwest this afternoon as 
dry northwesterly flow aloft remains in control from the Pacific northwest to 
the Mississippi River. Precipitable waters  across the region range from approx 0.4 
to 0.7 inches which is about half of what should be observed in 
early September. Not surprisingly this has allowed temperatures to 
warm up once again...with early afternoon readings /lower 100s/ 
already exceeding climatological normals for 1 September. 


The forecast through middle week will remain one of dry conditions and 
above normal temperatures as dry northwesterly flow remains in 
place. 500 mb heights will vary little from day to day and a blend of 
the best performing bias corrected guidance continues to yield highs 
in the 105-110 range through Wednesday. Thus...very few changes were 
made to the forecast through middle week. There will be a gradual 
increase in moisture across Arizona late Wednesday night into 
Thursday with today\s 12z GFS indicating some showers breaking out 
across the deserts early Thursday morning. Not buying into this 
solution as point soundings across the deserts depict a very 
unfavorable dry layer below 500mb. More favorable bl do not 
materialize until Thursday afternoon...which is when climatology-like probability of precipitation 
were introduced into the forecast. 


Moisture levels slowly return to a more monsoon like profile where 
afternoon and evening thunderstorms will be possible across the 
central and eastern Arizona higher terrain...including southern Gila 
County...for Thursday and Friday afternoons. Most of the activity 
will remain North-East-south of the Phoenix area...with greater 
chances of seeing storm outflow intrusions and the ever-present 
threat for blowing dust along those boundaries across the Lower 
Desert elevations. 


Along with additional Gulf moisture spreading over northern 
Mexico...forecast models continue to depict the formation of a 
tropical system off the central Mexican coast and anywhere from 
300-500 miles south of the Baja California tip by late Wednesday. Where earlier 
NHC forecasts had a 50 percent probability for development in the next 5 
days...their latest forecasts are now in the high chance range at 70 
percent. By the late Friday/Saturday time period...the tropical 
system could be tracking up along the southwestern Baja California coast. 
Also far to our northwest...renewed troughing develops over the 
Pacific northwest coast...eventually sliding down the California coast by the 
late week. The combination of increasing humidities and cloudiness 
from the potential tropical moisture tap along with falling upper 
heights will allow daytime temperatures to cool down by the late 
week/weekend. 


Late Friday through the coming weekend...disagreements between the 
medium range operational and ensembles members continue with how they 
handle 1) the tropical system and 2) the strength...evolution and 
residence time of the troughing to our northwest. The tropical 
system is brought northward and quickly moves into the broad mean 
trough flow over the region in the GFS by early next week...the 
European model (ecmwf) keeps the system compact and tracks it west out into the ocean 
before attempting to turn it back towards the southwest U.S. During 
the same time frame. Troughing over the West Coast for the weekend 
is stronger with the GFS solution but strong for early next week 
with the European model (ecmwf). While the pattern continues to develop made minor 
adjustments to the pop forecast...introducing some slight chance 
coverage towards the Colorado River valley and southeast California for 
Sunday and nudging probability of precipitation from Phoenix eastward upwards a bit as there 
is some model consensus about the deep monsoon moisture profile and 
energy expanding into the region from the Gulf of California. Temperature 
forecast for the weekend and early next week becomes tricky with the 
return of moisture and storm chances...but all the consensus and 
best performing extended temperature guidance were indicating a 
significant cool down by early next week...with well-below normal 
temperatures and some Lower Desert elevations possibly struggling to 
hit the 100f mark. 


&& 


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


Strong high pressure at the surface and aloft...and a very dry 
airmass...will keeps skies mainly clear through the taf 
periods...with winds remaining on the light side...mainly following 
typical diurnal trends. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Thursday through Monday... 
monsoon moisture returns to the region during this period along with 
an uptrend in shower and thunderstorm chances. Accordingly 
humidities trend upward and high temperatures trend downward. Over 
the weekend minimum humidities climb well above 20 percent and high 
temperatures dip below normal. With the return of thunderstorms to 
the area...the potential for strong and erratic winds from distant 
storms also returns. 


&& 


Psr watches/warnings/advisories... 


Arizona...none. 


California...none.
