NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
939 am MST Thursday Sep 3 2015 


Synopsis... 
increasing southwesterly flow aloft is expected to pull tropical 
moisture from the eastern Pacific northward into the 
region...increasing thunderstorm chances across south central Arizona 
today and Friday. As the winds aloft become more westerly over the 
weekend...somewhat drier air is expected to move into the region and 
will reduce shower and thunderstorm chances through Sunday. A 
temporary return to more southerly flow will then bring an upswing in 
monsoon activity early next week before a middle-week period of quiet 
thunderstorm activity. 


&& 


Discussion... 
per infrared satellite imagery from last evening through this early 
morning...it appears a near persistent stream of clouds and moisture 
was present from the Baja California peninsula stretching northeast through Southeast 
Arizona and into the western half of New Mexico. This bodes well as 
the upper level trough continues to push onshore to 
California...pinching the southwest flow and increasing upper level 
southwest winds through Arizona to 50-60 kts at 300mb. The plume of 
high moisture remains over Sonora this morning...slowly inching 
northward as Tucson saw a subtle increase in the 12z radiosonde observation this 
morning to just over 1.5 inches while Phoenix remained below 1.4 
inches...an increase from the 00z sounding but a sharp drop from the 
previous day's 12z launch. Temperatures again are running right about 
the same as the previous day with dewpoints on the rise...compared 
with yesterday as we saw a gradual decline in moisture through the 
day. Starting the day with a significant clear slot in the way of 
clouds over southwest and south-central Arizona I believe will help 
aide in convective initiation later this afternoon...what we lacked 
yesterday. Minor changes to the forecast package for timing of 
thunderstorm development but the trend looks on track. 


Previous discussion.../225 am MST 3 September/... 
today through Friday... although yesterday turned out to be much 
less active weatherwise then what was expected...due to drier air 
being advected into south- central Arizona by more westerly middle-level 
winds...it still appears that today...and to a lesser extent on 
Friday will see more convective activity...as a return to more 
southerly low-middle level flow is expected to pull at least some 
moisture back northward into south- central Arizona. Although the 
latest GFS model run now only raises precipitable water values to around 1.50 
across the phx area...a more favorable vertical shear environment and 
outflows from storms to the south is expected to allow at least some 
thunderstorm activity to develop from central Maricopa County 
eastward. This forecast is also being supported by the latest (00z) 
wrf4km/nmm6km high-res model runs...with both of them showing a very 
sharp western edge to the convective activity over central Maricopa 
County...with much drier air to the west greatly limiting 
thunderstorm development. Although the strong winds aloft (50kt at 
300mb) will limit rainfall amounts due to the rapid movement of 
individual cells...these strong winds will likely enhance outflow 
winds from these storms...with some of them approaching...or even 
reaching severe limits. 


Although available moisture will be somewhat less on Friday...even 
stronger winds aloft will help to destabilize the atmosphere 
further...which should allow at least some storms to develop from 
Phoenix eastward. The combination of cooler air aloft and increased 
cloudiness/convective activity will help to hold high temperatures down 
across the region both days...with many Lower Desert locations 
across south-central Arizona seeing highs only in the middle-upper 90s. 


Saturday and Sunday... somewhat less convective activity is expected 
during this time period as drier air works its way eastward into 
south-central Arizona. Still...at least slight chance probability of precipitation are warranted 
each day across the lower deserts of south- central Arizona as precipitable water 
levels remain in the 1.0-1.3 inch range and the vertical shear 
profile remains favorable through the column. 


Monday through Tuesday... although forecast confidence levels are 
still rather low this far out...a increase in available moisture as 
the flow below 500mb becomes a bit more southerly is expected to 
allow precipitation chances to rise a bit during this time period. Somewhat 
warmer air aloft will also allow temperatures to warm to above normal 
values. 


Wednesday... the GFS and the Euro are now both showing increasing 
westerly flow across the region as the main upper-level high center 
shifts to our south during this time period...with noticeably drier 
air moving into the region...which should greatly reduce 
thunderstorm activity across south-central Arizona. 


&& 


Aviation... 
south-central Arizona including kphx...kiwa...and ksdl... 
quiet weather remains in place across the region this morning. 
However it still appears that this afternoon has the potential to be 
busy...especially to the east of Phoenix. Will stick with the idea of 
thunderstorms in the vicinity/vcsh at all sites from late afternoon Onward. Most numerical 
guidance brings in storms and outflows shortly after 00z and I leaned 
heavily on that timing. Could see scattered showers and ceilings around 
10kft linger into the overnight hours. 


Southeast California/southwest Arizona including kipl and kblh... 
aside from high clouds...expect minimal weather-related aviation 
impacts through Friday morning. Diurnal winds with occasional late- 
afternoon gustiness anticipated. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Saturday through Wednesday... 
elevated moisture will remain in place across Arizona this weekend 
through the middle of next week...whereas drier than normal air will 
reside west of the Colorado River. Humidities will fall into the 20-30 
percent range each afternoon across Arizona and into the 10-20 
percent range to the west. Overnight recoveries at all sites will be 
good/excellent. Winds will follow typical upslope/downvalley patterns 
outside of thunderstorm induced outflows.
