NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
406 am MST Monday Sep 1 2014 


Update...aviation and fire weather discussions. 


&& 


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... 
dry west-northwest flow remains over the southwest states today as 
broad troughing encompasses much of the Continental U.S. Keeping early am skies 
over the forecast area mostly clear. Subtropical ridging remains over 
the far southern tier of the country and Mexico as a result with high 
pressure centers over the Gulf of Mexico/southeast Texas coast and over 
northern Sonora/Gulf of California. More recognizable amplified ridging 
remains over the eastern Pacific...starting just off the Baja California coast 
extending towards 140w/41n. Shortwave troughing will continue 
tracking eastward across the northern tier of the country through the 
early week...lifting northward enough to allow the upper ridge to 
reorganize and consolidate to our east by Tuesday. 


500mb heights will generally hold at or just above the 590dm 
mark...supporting continued above normal daytime temperatures for 
much of the coming week. 850mb temperatures near 28/29c each 
afternoon translate to high temperatures just shy of the 110f mark 
over the south-central deserts...and just a few degrees warmer out 
west for el centro/Yuma/lower Colorado River valley. Where upper 
ridge heights will work to keep our warmer daytime 
temperatures going...the repositioning of the ridge to our east will 
transition lower to middle level winds back to more southerly headings. 
Inverted wave activity over northern Mexico will help increase 
moisture levels to our south through the early week with 8c or 
greater 850mb dewpoints along the international border and far 
eastern Arizona by Wednesday evening. 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... 


Through 03z Tuesday...dry westerly flow aloft across the region 
providing clear skies and light wind at all taf sites. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Wednesday through Sunday... 
monsoon moisture will slowly increase across Arizona Wednesday 
through Sunday. A chance of afternoon and evening mountain thunder- 
storms will redevelop over the north through east of Phoenix 
Thursday through Sunday. Minimum humidities Wednesday will range 
from 12 to 16 percent...increasing substantially by Sunday into the 
30 to 35 percent range. Good recovery at night. Afternoon 
temperatures will continue in the above normal range Wednesday 
through Friday...then fall below normal Saturday and Sunday due to 
increasing humidity...clouds...and a chance of showers. 


&& 


Psr watches/warnings/advisories... 


Arizona...none. 


California...none.
