NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
227 am MST Tuesday Sep 16 2014 


Synopsis... 
moisture will continue to increase across the area today as Tropical 
Storm Odile approaches the region. There will be an elevated risk of 
heavy rain and flooding across the area through late week before 
drier air returns by the weekend. 


&& 


Discussion... 
showers continue to develop and dissipate across southern Arizona 
this morning along a strong middle level Theta-E gradient. A strong 
surge of moisture preceded these storms late Monday night as 
dewpoints jumped into the middle 60s and lower 70s and precipitable waters  climbed to 
around 1.6-1.7 inches. Along with the showers...clouds have 
increased quite a bit this morning which has kept temperatures well 
into the middle 80s as of 09z. 


In the short term...the middle level instability gradient and 
associated shortwave trough will slowly move northward today and 
coupled with the recent increase in available moisture...scattered 
showers and thunderstorms are expected across nearly the entire area 
later today. Winds in the 700-300mb layer should be strong enough to 
keep storms moving and mitigate a widespread flash flood threat 
today...but locally heavy rain is possible along with the usual 
hazards /localized bldu and gusty winds/. Since it doesn\t appear 
that there will be a complex of storms over the normally favorable 
dust-prone areas to our southeast...I will leave blowing dust out of 
the forecast today as it should be very isolated in nature. 
Showers/storms could persist into the evening and overnight hours as 
the shortwave trough will be slow to exit the area and move into 
North/East Arizona. 


Wednesday\s forecast is tricky as the best forcing associated with 
T.S. Odile will still be well to the south and subsidence behind the 
departing shortwave could also mitigate widespread storm coverage. 
The GFS and European remain in good agreement this morning with both 
00z runs indicating the remnant low from T.S. Odile will move into 
Arizona Wednesday night. The models are continuing their slight 
eastward trend with the track which is cause for concern. As the 
circulation moves into Southeast Arizona on Wednesday...slightly 
drier air from the north will be advected into the 
area...downslope...and dry out even further. This will likely result 
in a very pronounced back edge to any precipitation that develops. The 
tricky part is trying to ascertain exactly where this back edge will 
reside. Some of the earlier hi-res WRF models /admittedly they have 
a bit of a dry bias/ suggested the back edge would be in the West 
Valley of the metropolitan area. This morning\s 00z runs of the same models 
/and the NAM for that matter/ are also farther east and suggest the 
back edge will reside somewhere across the East Valley with the 
greatest impacts in the mountains east of Phoenix. Never a good idea 
to buy into one run of one model 100 percent...but this trend will 
certainly need to be monitored. For now I made slight reductions to 
the probability of precipitation across southeast California on Thursday with more focus 
placed on southern Gila County. The Flash Flood Watch will remain in 
place unchanged. 


Both European model (ecmwf)/GFS seem to be on the same Page ejecting the remnant low 
late Thursday/early Friday with modest dry advection Friday through 
Sunday. Bl moisture won't be scoured out entirely and there should 
still be a chance of afternoon showers/storms east of Phoenix 
Friday/Saturday. Decent flow /around 20-25kts/ in the 700mb-300mb 
layer and a few pv perturbations could be enough to serve as the 
trigger Friday/Saturday and I will keep probability of precipitation as-is. From that point 
into early next week I will hang onto climatology probability of precipitation as mixing ratios 
will remain above 6-7 g/kg east of Phoenix. 


&& 


Aviation... 
south-central Arizona including kphx...kiwa...and ksdl... 
moisture spreading northward from remains of Hurricane Odile is 
expected to keep broken-overcast ceilings over the Phoenix area terminals 
through the forecast period. Ceilings...that could fall as low as 7k feet 
above ground level this morning...could fall as low as 5k feet above ground level late tonight and 
early Wednesday as shower activity begins to develop over the 
region. Winds are expected to remain mainly easterly through the taf 
period...outside of any convective activity...which could bring a 
brief period of gusty winds to the affected terminal(s). 


Southeast California and southwest Arizona including kipl and kblh... 
a very moist airmass moving into the region is expected to keep 
broken-overcast ceilings over the terminals through the taf period...with ceilings 
as low as 3k feet above ground level at kblh this morning as a very moist airmass 
surges northward from the Gulf of California. Additional moisture 
associated with the remains of Hurricane Odile that will be moving 
northward into the region late this afternoon/evening will likely 
produce scattered showers/thunderstorms over the region...thus will 
introduce vcsh into the tafs during this period. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Thursday through Monday... 
lingering moisture from the remains of Hurricane Odile will keep the 
changes for showers/thunderstorms going over the region on Thursday 
and Friday...with heavy rainfall and localized flooding possible 
over south-central Arizona. Increasing westerly flow aloft will then 
gradually push drier air into the region from the west from this 
weekend into early next week...reducing the chances of 
showers/thunderstorms over the region...with convective activity 
likely to be confined to the higher terrain north and east of 
Phoenix by Monday. Afternoon humidity values...which will remain in 
the 35-50 percent range with excellent overnight recoveries on 
Thursday and Friday...are expected to fall into the 20-35 percent 
range by Monday. Winds to remain mainly on the light side...except 
around thunderstorms.
