NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
325 PM MST Wednesday Jul 23 2014 


Update...to aviation and fire weather discussions... 


&& 


Synopsis... 
a strong high pressure system is forecast to continue over the 
region this week...resulting in very hot temperatures through 
Friday. At same time...monsoon moisture will slowly increase over 
the area...with occasional cloudiness at times. Increased 
moisture...combined with several weak weather disturbances from 
Mexico...are forecast to increase the chance of afternoon and 
evening showers and thunderstorms...mainly across Arizona...this 
weekend and early next week. 


&& 


Discussion... 
tonight and Thursday... 
monsoon moisture has pushed a little deeper into southeast and south 
central Arizona the past 18 hours...but afternoon temperatures are still 
on track toward the 112 to 117 degree f mark on the deserts. An 
excessive heat warning remains posted through Thursday...although 
the appearance of more moisture...clouds...and possible convective 
outflows from Southeast Arizona could reduce the potential heating 
curve for Thursday...I.E. A few degrees below excessive heat warning 
criteria. For now...height and thickness values for Thursday support 
another potential heat warning day...and...modeled soundings for 
Phoenix forecast surface dewpoints to drop from 61f Thursday morning 
to 44f by late afternoon. Also...due to the unknown variability in 
moisture tonight and Thursday...we decided to keep the excessive 
heat warning going for Thursday although it might be marginal. 


Convective wise...a slight chance of showers and thunderstorms are 
expected this evening on the south central Arizona deserts...including 
Phoenix...with higher probabilities over the mountains east of 
Phoenix this evening. 


On Thursday...partly cloudy skies will cover the area...however a 
slight chance of late afternoon showers/thunderstorms will be confined to 
parts of southwest Arizona...and over the mountains east of Phoenix. 
Again the excessive heat warning continues for Thursday. 


Friday through Sunday... 
slightly cooler afternoon temperatures are forecast this period as 
the upper-level high weakens a bit...and a little more monsoon 
moisture spreads into the region. A better threat for afternoon and 
evening convection is expected...particularly Sunday through Tuesday 
as the possibility of minor upper level perturbations work into the 
area under southerly flow aloft. 


&& 


Climate... 


Record high temperature for the middle of the week. 


City July 23 July 24 July 25 
---- ------- ------- ------- 
Phoenix 114 in 2006 114 in 2006 115 in 1943 
Yuma 115 in 1959 117 in 1943 120 in 1943 


&& 


Aviation... 
south-central Arizona including kphx...kiwa...and ksdl... 
some easterly component to the winds will hold for the phx area 
terminals the rest of the afternoon...if not vrb out with speeds 
gnly 6kts or less. Hi-res models today all agreeing on gusty storm 
outflows moving into the phx metropolitan near 24/00z gnly from the east. 
Chances are better for storm outflows to impact the terminals moreso 
than organized storms. With such warm temperatures across the area 
today...not confident in strong storms making it to kphx...but ksdl 
and kiwa could at least have thunderstorms in the vicinity coverage. Debris clouds will fill 
into the region overnight...with broken-overcast ceilings at or above 12-15kft possible. 


Southeast California and southwest Arizona including kipl and kblh... 
monsoon storm coverage should mainly remain well east of kipl and 
kblh this afternoon and evening...with debris clouds more likely 
spreading in during the late evening and overnight. Could see 
scattered-broken coverage likely for kblh...with less for kipl. Kblh winds to 
maintain some southerly component through the evening...unless 
disrupted by a passing storm outflow. Vrb afternoon winds for kipl 
to become westerly overnight. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Saturday through Wednesday... 
slightly cooler afternoon high temperatures are expected through the 
period...as upper level high pressure weakens and slides further to 
the south. Even so...readings will still be slightly warmer than 
normal. An increase in moisture is possible as the high slips to the 
south...though minimum afternoon daily humidity levels will still 
dip below 20 percent. Overnight recovery should however be moderate 
to good. There will be a daily threat of thunderstorms...but these 
will be mainly concentrated in the higher terrain of eastern Arizona. 
Outflow boundaries moving into the lower deserts will be capable of 
producing strong wind gusts. Further west across southeast California...the chance 
for rain and thunderstorm impacts will be even lower. Winds to 
generally follow diurnal and terrain driven headings...with mostly 
light speeds.
