NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Phoenix Arizona 
255 PM MST Sat Aug 30 2014 


Update... 
updated aviation and fire weather sections. 


&& 


Synopsis... 
mostly clear skies with low humidity values will continue to provide 
above normal afternoon temperatures through the middle of next week. 
The hottest temperatures will occur this weekend. Slight cooling is 
expected next week...along with an increasing chance of afternoon 
and early evening thunderstorms over eastern Arizona starting around 
next Thursday. 


&& 


Discussion... 
clear skies and strong ridging aloft is again allowing for some hot 
temperatures across the region. Highs this afternoon will break 110 
in many desert spots across southeast California and southwest 
Arizona and approach 110 across the south-central Arizona deserts 
including the Phoenix area. Will keep the excessive heat warning 
going through early this evening for southeast California and 
southwest Arizona. Dry air remains entrenched across the region with 
precipitable water values two Standard deviations below normal. 
Surface dew points generally in the 30s and 40s will create larger 
than typical diurnal temperature swings over the next several days. 


The first signs of some flattening in the upper level ridge is now 
happening as a series of shortwaves have begun to carve out broad 
scale troughing from the Great Basin northward into southwest 
Canada. This flattening will gradually bring down upper heights 
across the Desert Southwest with some slightly cooler temperatures 
to follow. Expecting to lose maybe one degree on our highs for 
Sunday and probably another degree or two on Monday. Then the broad 
troughing lifts to the northeast...but while keeping heights fairly 
steady across our region Monday through Wednesday. Since model 
temperature guidance has been a bit too cool the past few 
days...have kept with our trend of going slightly above guidance 
which gives US highs 2-3 degrees above normal. 


For Thursday and Friday...models show a fairly strong shortwave 
trough moving through the Pacific northwest along with a weaker 
shortwave approaching California from the west. The sub-tropical 
high then shifts eastward mainly centered over the western Gulf of 
Mexico. There are some indications of a return to weak southeasterly 
low level flow over northern Mexico and Southeast Arizona...but it 
is still too early to say when any meaningful monsoonal moisture 
will venture back into our area. Given the European has not handled 
the moisture return very well lately...leaning toward the drier GFS 
which doesn/T bring any chances of rain until Friday. Temperatures 
should cool down even further during the latter part of the week as 
upper heights fall in response to the southern shortwave digging 
into central California and the Great Basin. 


&& 


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


Clear skies except for very thin cirrus through Sunday. Southwest 
and west winds will prevail through Sunday over south-central 
Arizona...including Phoenix metropolitan...with gusts this afternoons of 
15-20 kts. South and and southeast winds will predominate over 
southwest Arizona and southeast California with similar gusts. Winds 
just above the low level inversion tonight will be fairly strong 
with 20-25 kts common...favoring the aforementioned directions. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Tuesday through Saturday... 
southerly flow and subsequent low level moisture will slowly return 
to the region through the work week...gradually nudging up dewpoint 
readings while helping to keep temperatures closer to normal 
readings for early September. Very limited shower and thunderstorm 
activity is expected to begin over the southeastern and far eastern 
Arizona higher terrain by Wednesday...before slight chances enter the 
forecast for the foothills and higher terrain of southern Gila 
County by Friday. While moisture at this time is not plentiful over 
the Lower Desert elevations...gusty outflow winds from distant 
thunderstorms may reach Lower Desert locations. Minimum humidities 
of 10-15 percent are expected over the lower deserts the first half 
of the week increasing closer to 20 percent during the latter half 
of the week. Similarly...overnight recovery will be fair-good the 
first half of the week and increase to good-excellent at most places 
during the latter part of the week.
