NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
220 PM MST Friday Sep 4 2015 


Update...updated aviation and fire weather discussions. 


&& 


Synopsis... 
sufficient moisture will remain over much of Arizona today providing 
good shower and thunderstorm chances...particularly across the 
eastern half of the state. Somewhat drier air will move into the 
region over the weekend...reducing rainfall chances very slightly. 
While some thunderstorm chances will persist during the first half 
of next week...a substantially warmer and drier airmass will spread 
into the area for the latter half of the week. 


&& 


Discussion... relatively strong upper level trough remains situated 
along the Pacific northwest coast early this afternoon putting Arizona 
under southwest flow aloft. Infrared imagery at 1 PM showed ts Kevin off 
the southwest tip of Baja California California...and the southwest flow was tapping 
into the middle/high level moisture being shed off of Kevin. Much of 
this moisture has overspread the eastern half of Arizona. Morning 
soundings showed a moist but not especially unstable airmass across 
south central Arizona with precipitable water values near 1.5 inches but rather skinny 
and meager cape. Low Cape values were due to the modest lapse rates 
and rather moist adiabatic profiles as seen in the 12z radiosonde observations. 
Steering flow this afternoon and evening will be southwesterly...and 
the upper streamlines depict a laminar and slightly confluent 
flow...not conducive to strong storm development. Dynamically 
speaking...there will be weak ripples moving in the southwesterly 
flow but no strong short waves appear ready to move across Arizona 
later today. However there is a jet streak racing across central 
Arizona...putting the central deserts under the favorable right rear 
quadrant later this afternoon. 


At 1 PM surface dew points over the central deserts were elevated and 
mostly ranged from the upper 50s to low 60s. With moisture elevated 
and instability limited...and dynamics being a mixed bag...it is 
tough to say just how the convection will play out today. Some 
mesoscale hi res models such as the hrrr and wrf4km suggest we will 
see storms in the Phoenix area tonight. As such we will keep about a 
30 percent chance for showers and thunderstorms across south central 
Arizona later this afternoon and overnight tonight. 


For this weekend...upper troffing remains situated along the West 
Coast and Arizona will stay under a southwest flow aloft. 
However...latest guidance does not really dry out the eastern half 
of the state...especially in the lower levels. Precipitable water values are 
forecast to remain near or above 1.5 inches over south central 
Arizona through Sunday...even though much of the moisture from Kevin 
will have already lifted out to the northeast by Saturday evening. 
Again...dynamics not especially impressive either day but there will 
likely be weak disturbances moving through the southwest flow from 
time to time...increasing the threat for showers or storms. 
Streamlines remain rather laminar and southwesterly...similar to 
what is seen today. We feel it is a bit optimistic to remove the 
threat for convection from the forecast this weekend...so we will 
raise probability of precipitation slightly and keep south central Arizona under at least a 
slight chance for afternoon/evening storms both Saturday and Sunday. 


Convective potential for early next week may be somewhat more muted 
than recent days as deep layer winds veer somewhat more westerly as 
troughing translates into the Great Basin and northern rockies. 
Still...boundary layer moisture will be difficult to completely 
scour out and some modest infusion of midlevel moisture peeling off 
the remnants of Kevin may be possible. However...there remains some 
disconnect with the more quality tropical moisture to the 
south...and the best WV transport may be deflected around the 
forecast area. In addition...with middle latitude troughing lifting to 
the north and heights aloft rising ahead of the remnant tropical 
system...models depict substantial midlevel warming and increased 
convective inhibition. Kept some modest near climatology probability of precipitation 
through Tuesday...however measurable rainfall at Lower Desert 
elevations may be difficult to come by. 


Some minor uncertainty still exists for the latter half of next week 
as subtle differences in the subtropical ridge position will dictate 
if and how quickly moisture is completely scoured south of the 
forecast area. Mesoscale processes and outflow from sonoran mesoscale convective system/S 
may allow for Gulf surges and boundary layer moisture 
advection...but definitively forecasting and timing such events 
would prove fruitless at this time. Regardless...500 mb height rises at or above 
590dm will result in temperatures peaking back above normal under 
gradually more compressional subsident flow. 


&& 


Aviation... 
south-central Arizona including kphx...kiwa...and ksdl... 
scattered-broken middle clouds at or above 10kft can be expected this this evening and 
overnight...with some partial clearing of debris clouds by Saturday 
morning. Upper level disturbance will keep potential for isolated to 
widely scattered thunderstorms until about 08z tonight. With the 
storms comes the threat for gusty outflows and local blowing dust to 
impact terminals although confidence too low to introduce wind shifts 
or reductions in visibility in the tafs at this time. 


Southeast California/southwest Arizona including kipl and kblh... 
surface winds will continue to favor south at kblh...becoming 
westerly at kipl sometime after 03z this evening. Skies generally 
clear with a few middle-high clouds during period. Anticipate storm 
activity will be isolated and confined to areas east of the lower 
Colorado River valley. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Monday through Friday... 
storm chances will continue over south-central Arizona before 
trending down significantly Wednesday. Humidities will also begin to 
trend down from west to east across the entire forecast area next 
week...beginning as early as Monday. A gradual warming trend will 
ensue during the period climbing to several degrees above normal by 
next Thursday.
