NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
247 PM MST Thursday Aug 21 2014 


Synopsis... 
there will be an increased chance of showers and thunderstorms 
across the region this afternoon and evening as an upper level low 
pressure system moves through the area. Storm chances will decrease 
Friday and through the weekend as drier air overspreads the area. 
Below normal temperatures are forecast through Saturday...gradually 
returning to normal early next week. 


&& 


Discussion... 
thunderstorm activity has rapidly picked up this afternoon across 
our southeast California zones...the lower Colorado River valley... 
and as far east as central La Paz and Yuma counties. Some of these 
storms have quickly clustered and evolved to severe status with 
strong winds in excess 55kt...other isolated storms have been 
efficient rain producers with radar rainfall estimates of 1-2 inches 
per hour. 


Cloud cover and cooler temperatures across south-central Arizona 
created a more stable environment and thus took a bite out of the 
convective potential this afternoon and has kept storm activity to a 
minimum so far. The high at Phoenix peaked out at 88 degrees and 
that was at 10 am this morning. However...as the low gradually 
shifts east...the cold core 500mb temperatures/-10 to 12c/ will eventually 
move over south-central Arizona...improving lapse rates/instability. 
Expect showers/thunderstorms to form and eventually spread east 
across Maricopa County/Phoenix metropolitan area by early 
evening...continuing into the higher terrain of southern Gila 
County...northern and eastern Arizona before midnight. 


The low will move move across the state tonight...the trough axis 
expected to be draped across the central Arizona by late Friday 
morning. Middle level flow behind the departing trough turns sharply 
out of the west late tonight into Friday...so moisture gets scoured 
out and the flow becomes less favorable for storms Friday afternoon. 
Would anticipate that the atmosphere will be pretty worked over and 
more stable across our entire forecast area from this evenings 
activity that little in the way of convective storms will 
materialize Friday. Still keeping slight chance probability of precipitation going across 
southern Gila County for Friday afternoon...and much of the same is 
expected for Saturday and Sunday as low level mixing ratios continue 
to fall to around 5-6 g/kg this weekend. Daytime temperatures will 
continue to be below normal as we end the week...holding in the middle 
to upper 90s over the lower deserts Friday afternoon...barley 
breaking the 100 degree mark Saturday afternoon...and a few more 
degrees of warming for Sunday. 


There is a general agreement among the operational models and 
ensembles that moisture will return to the area Monday/Tuesday... 
although at this point there does not appear to be any clear signals 
on which day will be active. Going to retain a low-grade monsoon pop 
forecast each afternoon Monday through Thursday along with near 
normal temperatures. 


&& 


Aviation... 
south-central Arizona including kphx...kiwa...and ksdl... 
persistent cloudiness has kept temperatures well below normal across 
the area. Consequently...instability is diminished and the threat 
for thunderstorms has decreased. However...instability will increase 
again late this afternoon and this evening as an area of low 
pressure moves into southwestern Arizona. Isolated to scattered storms 
are possible across the Phoenix area...particularly in the 01z-05z 
period. The strongest storms will be capable of producing heavy 
rain...strong to severe wind gusts and perhaps even large hail. Ceilings 
may also lower to around 7k feet with occasional visibility restrictions 
below 6sm. Conditions will improve after 06z with a break in the 
monsoon activity beginning Friday. 


Southeast California and southwest Arizona including kipl and kblh... 
thunderstorms will continue to increase in coverage this afternoon 
at both kipl and kblh. The strongest storms will be capable of 
producing heavy rain...strong to severe wind gusts and large hail. 
Ceilings may also lower to around 6k feet with occasional visibility 
restrictions below 6sm. Conditions will improve after 04z with a 
break in the monsoon activity beginning Friday. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Saturday through Wednesday... 
humidities trend downward some more over the weekend before 
rebounding some next week. Air will be driest over southeast 
California and Haines index values climb to 5 before improving by 
Tuesday. Haines values will be significantly lower east of there due 
to better moisture. Overnight recovery will remain good...less so 
over southeast California. Storm chances will be slight and limited 
to the higher terrain of south-central Arizona through 
Tuesday...expanding westward Wednesday. 


&& 


Psr watches/warnings/advisories... 


Arizona...none. 


California...none.
