NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
307 am MST Tuesday Sep 30 2014 


Synopsis... 
dry northwest flow will establish itself over the area this 
week...keeping skies mostly clear and rainfall chances none. 
Temperatures will begin the week slightly below normal and gradually 
warm through the week as high pressure strengthens over the west. 


&& 


Discussion... 
large upper low responsible for this weekend's weather event across 
the southwest states now is circulating into the plains states...with 
dry northwest flow draped across much of the western Continental U.S. This am. 
Nearly cloudless skies observed across southeast California and much of 
Arizona...save for some middle-level stratus decks skirting the northern Arizona 
border near Page. Generally little change noted on area temperatures 
this morning compared to Monday...with low 60s to low 70s observed at 
most sites. While the broader dewpoint trend has been drier through this 
early week...observed values have widely varied during the overnight 
hours over many of the Lower Desert elevations. Expect this to 
continue the next few mornings as surface conditions still hold some 
moisture from recent rainfall and temperatures haven't been too warm 
to help evaporate this moisture away. Where the mornings will have a 
wide range of values... afternoon mixing for the next few days should 
drop readings into the upper 30s to low 40s...possibly even drier 
over portions of southeast California. 


Dry northwest flow will persist through Thursday over much of the 
west...with another swift shortwave disturbance dropping out of 
British Columbia Canada and into the Great Basin states late 
Wednesday into Thursday. 850mb temperature plots and mslp analysis 
show the front stalling over northern Arizona...with north to 
northeasterly flow filtering down the Colorado River valley and 
through the Mogollon Rim. Noticeably breezy conditions will develop 
along the Colorado River of 10 to 15 miles per hour with some periods of 
enhanced gustiness possible Thursday into Friday. With lowered 
shortwave heights to the north/northeast of Phoenix...near or just 
below normal temperatures (low 90s) will hold through Thursday. The 
western forecast area being just out of range of the thermal profile 
of the front will see slightly warmer conditions in the middle to upper 
90s. 


Pacific ridging will quickly build into the southwest deserts 
beginning early Friday. Temperatures under this pattern look to peak 
on Saturday with the warmer western deserts in the 100-105f range and 
94-99f for the lower Arizona deserts with mostly clear skies and light 
winds. By the Sunday-Monday period...the upper ridge circulation 
center will transition to our east/southeast as broad 
troughing/shortwave energy from over the Great Lakes expands back 
into the central portions of the country and another area of weak 
troughing/lower height anomaly moves in along 30n in the eastern 
Pacific. 


Activity from the eastern Pacific tropics could play a role in the 
extended period by the middle part of next week. Latest NHC forecast 
has an area well south of Acapulco, Mexico prognosticated for tropical 
cyclone formation at 90 percent within the next 5 days. Both the GFS 
and European model (ecmwf) pick up on the potential tropical system...the next name on 
the cyclone list is Simon...as it moves further into the Pacific 
waters and eventually turning northwestward. While it is far too 
early to hang a hat on any one model solution...storm path or storm 
evolution...the repositioning of the upper ridge to our 
east/southeast could transport some elevated moisture fields that 
work up the Gulf of California back into northern Mexico and the 
southwest states. With upper ridge heights removed from the area 
during this period...temperatures will scale back to more normal 
readings and possibly cooler if elevated dewpoints and humidities 
make some sort of a comeback. 


&& 


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


Very weak low/middle level gradients and clear skies will lead to very 
light and somewhat diurnal winds across the deserts over the next 24 
hours. Winds at the taf sites will often be light/variable at or below 5kt. 
Clear skies tonight should help to set up favorable drainage 
conditions and contribute to winds turning back towards the east or 
southeast at kphx and kiwa after 06z...but speeds will be light. 


No aviation issues at any terminal through Tuesday evening at least. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Thursday through Monday... 
with virtually no chance of rainfall through the 
period...temperatures will be maintained in a slightly above average 
category. Minimum humidity levels will remain relatively steady 
throughout the period...dropping into the teens across lower 
elevations. Overnight recovery will be good. Winds will be 
unseasonably light with occasional afternoon breeziness in upslope 
areas. 


&& 


Psr watches/warnings/advisories... 


Arizona...none. 


California...none.
