... Storm survey for July 26 storm in Phoenix...

The National Weather Service in Phoenix conducted a storm survey for
the storm that impacted north Phoenix on Saturday July 26. The area
surveyed stretched from cactus Road north to Union Hills drive... and
Cave Creek Road east to Tatum Road. Widespread damage was noted with
numerous trees down throughout the area. Some trees exceeded two
feet in diameter with many uprooted. A number of power poles and
utility light poles were knocked down. In some cases... even street
lights were stripped off of standing power poles. Roof damage was
noted on many homes and in some cases roof attachments such as solar
panels... awnings... and porches were blown off.

The area impacted was about three and half miles by three and a half
miles... or approximately 12 square miles. Most damage was consistent
with wind speeds 50 to 70 mph. However... there were several pockets
of more severe damage... most notably along Greenway Parkway between
40th street and Tatum Boulevard... 40th street and Union Hills
drive... and in Paradise Valley Park. Most fallen structures were
blown towards the west or southwest... indicative of very strong
straight line winds.

Damage was quite widespread... indicative of a macroburst from a
severe thunderstorm and this is also confirmed through Post analysis
of one minute terminal Doppler weather radar.

Much more information... including maps and photos from the NWS and
volunteer storm spotters can be found upcoming on our website at:

26 storm.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
225 PM MST Monday Jul 28 2014 


Update...updated aviation and fire weather discussions. 


&& 


Synopsis... 
there will be a continued chance of showers and thunderstorms across 
the forecast area this afternoon and evening...before drier air 
moves into the region Tuesday through late week. Storm chances will 
increase again Friday into the weekend as moisture moves back into 
the southwest United States. 


&& 


Discussion... 
a good deal of thunderstorm activity has popped up across northern 
Arizona this afternoon due to a broad upper level circulation moving 
northward across Southern California. Visible satellite imagery also 
showing patches of cumulus development across our County Warning Area from western 
Maricopa County/Gila Bend area...westward across southeast California into 
Joshua Tree np. Convection has been slow to initiate across our County Warning Area 
this afternoon given the lighter winds aloft and the more subsident 
nature to the atmosphere. Still...given the amount of precipitable 
water in the atmospheric profile...and good surface heating...we 
will continue to maintain slight chances of precipitation for some 
areas of our County Warning Area into the evening hours. The best chances...albeit 
slight will still be across south-central Arizona. Precipitation 
chances quickly dwindle this evening for southeast California...as 
all models agree that upper level flow will become westerly and 
drier later tonight. 


Tuesday through Sunday...a dramatic decrease the amount of 
convection across the area...with the focus for any precipitation in 
the mountains east of Phoenix through the middle of the week. Mean 
bl mixing ratios drop to around 6 g/kg during the middle part of the 
week and even climatology probability of precipitation may end up being too high. With drier air 
working into the area middle week...temperatures will likely take a run into 
the 105-109 range across the deserts. Consequently...there should be 
a slight drop-off by the weekend as deeper moisture makes its way 
back into the area. Still above 100 but somewhat lower than the middle 
week values. Made slight reductions to probability of precipitation across the board from 
Tuesday through Thursday based on latest guidance with the highest 
values displaced well east of the deserts. The monsoon moisture 
won\t be terribly far away...winds per the two-three most recent 
runs of the European and GFS bring increased mixing ratios back into 
the area Friday and almost certainly by the weekend. Precipitation chances 
once again look favorable for the latter portions of the forecast 
period although it\s still difficult to highlight one day vs another 
until we get a little closer. 






&& 


Aviation... 
south-central Arizona including kphx...kiwa...and ksdl... 
model guidance suggests that shower and thunderstorm activity will 
be limited this evening...mainly focused across the higher terrain 
outside of the Phoenix area. However...an outflow boundary from 
distant convection will likely result in a shift to easterly winds 
later this evening. 


Southeast California and southwest Arizona including kipl and kblh... 
there is a slight chance of a thunderstorm at kipl late this 
afternoon as isolated convection along the Baja California spine propagates 
into southeastern California. Otherwise...no aviation impacts expected with 
winds generally remaining light and diurnal at kipl and kblh. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Thursday through Monday... 
drier than normal conditions expected through Thursday. Storm 
chances will be slight and will be limited to the higher terrain of 
eastern Arizona. Late in the week and over the weekend...an 
increase in moisture and associated humidities is anticipated and 
storm chances...though slight...expand to the lower elevations. High 
temperatures trend downward as well. 


&& 


Psr watches/warnings/advisories... 


Arizona...none. 


California...none.
