NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
505 PM MST Sat Apr 19 2014 


Update...aviation weather discussion. 


&& 


Synopsis... 
a Pacific low pressure system moving east across Arizona will lead 
to a lingering slight chance of showers or thunderstorms across 
south central Arizona this evening. High pressure aloft will build 
into the area Sunday into early next week behind the exiting 
low...and lead to sunny days and clear nights along with sharply 
warming high temperatures. Breezy to windy conditions are expected 
next Tuesday into Wednesday as a dry weather system passes by to our 
north. The passing system will lead to cooler weather...with high 
temperatures falling to near seasonal normals on Wednesday. Higher 
pressure will return for the latter part of the next work week... 
bringing another warming trend and generally sunny skies. 


&& 


Discussion... 
upper level Pacific low continued to push eastward across the Desert 
Southwest early this afternoon with the main low center shifted into 
far south central Arizona. Most of the dynamics/q forcing has 
shifted into far eastern or Southeast Arizona...to the southeast of 
our County Warning Area...and the associated convection has shifted southeast of our 
area as well. One of the main vorticity maxes rotating through the base of 
the trough...and clearly seen in the vapor imagery...was trekking 
along the southern Arizona/Mexican border early this evening...and the positive vorticity advection 
induced convection ahead of it was pushing through far southeastern Arizona...well 
southeast of the greater Phoenix area. 


Otherwise...infrared imagery indicated partly cloudy skies across much of 
the the County Warning Area...as the cold air aloft moving over the deserts helped 
generate variable amounts of cumulus along with a few instability 
showers. Made a zone update for this afternoon to include slight 
chances of showers and thunderstorms across the southwest deserts of 
Arizona...based on increasing echo on radar as well as increasing 
and thickening instability cumulus. For later this afternoon and 
into the evening hours...the low will continue to shift east 
allowing drier and more subsident air to overspread the lower 
deserts. There will be a lingering slight chance of showers or 
thunderstorms from the greater Phoenix area eastward...with the best 
threat for any convection over higher terrain areas well to the east 
of Phoenix...and mainly east of Globe. By midnight expect most of 
the convection to have ended...and skies across most of the County Warning Area to 
become mostly clear. 


For Sunday...trough axis will shift into New Mexico...and high 
pressure aloft will build into the deserts from the west. There will 
be a bit of lingering moisture and instability over the higher 
terrain east of Phoenix...and as such we will keep around a 10 
percent chance of instability storms going east of Globe during the 
afternoon hours. Otherwise expect mostly sunny skies along with 
warming high temperatures. High temperatures will rise several degrees and 
into the low to middle 90s across the warmest lower deserts. High 
pressure aloft will build further on Monday...leading to some 
additional warming under generally sunny skies. 


For Tuesday into Wednesday...both the GFS and European model (ecmwf) continue to call 
for a rather vigorous Pacific upper trough to move east through the 
Desert Southwest...bringing considerable wind to the area Tuesday 
afternoon and evening...and leading to some concerns regarding 
potential for dangerous fire weather conditions. Too early at this 
time to issue a Fire Weather Watch...but this may be needed sometime 
in the next day or so should confidence in the event continue to 
climb. Otherwise this will be a typical April system for our 
County Warning Area...bringing wind and cooling and no precipitation. It appears to be a 
very dry system and skies should be mostly sunny for the most part 
both days. Despite the wind potential...this trough will likely pass 
to far to our north to bring significant cooling...and high temperatures 
are forecast to drop back to near seasonal normals on 
Wednesday...with the warmer deserts falling into the middle to upper 
80s. Flat upper ridging...and dry westerly flow aloft...will follow 
on Thursday for mostly sunny skies and a bit of warming with the 
warmer deserts climbing back into the lower 90s. 


Operational and ensemble model spread is somewhat higher than seen 
recently for the end of next week...however still remains relatively 
small in a seasonal sense. Flat ridging and/or quasi-zonal flow 
should predominate the general pattern for the majority of time with 
500 mb heights hovering not far from 576dm. This model average solution 
for heights aloft is slightly higher than previous model 
iterations...and consequently have edged forecast highs slightly 
warmer to just above climatological levels. There is still no 
evidence supporting any precipitation much of next week...with only 
very limited opportunity possibly arriving next weekend. 


&& 


Aviation... 
south-central Arizona including kphx...kiwa...and ksdl... 
through 03z sun...sct-bkn clouds at or above 12 thousand above ground level. Light and variable 
wind under 8 knots. From 03z sun to 19z sun...few clouds near 16 thousand 
mean sea level. Light and variable wind under 7 knots. 


Southeast California/southwest Arizona including kipl and kblh... 
through 19z sun...few clouds based near 16 thousand above ground level. Light south to 
southwest wind under 7 knots. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Tuesday through Saturday... 
westerly flow aloft will bring warm and dry conditions for Tuesday 
with well above seasonal normal high temperatures. A cooling trend 
ensues Wednesday and Thursday as a low pressure system moves into 
the Great Basin and the Pacific northwest. The biggest impact with 
this system will be an increase in wind area-wide Tuesday into 
Wednesday...with gusts up to 35 miles per hour possible...and even stronger 
gusts expected across southeast California and portions of the lower 
Colorado River valley. Minimum humidity levels also bottom out in 
the single digits during this time frame of strong 
winds...presenting an increased fire danger threat and the possible 
issuance of red flag warnings in some areas. Light winds...with dry 
and warmer conditions are on tap Thursday through Saturday as 
high pressure aloft builds back into the area.
