NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Tucson Arizona 
245 am MST Thursday Aug 21 2014 


Synopsis...an upper low over Southern California this morning will 
weaken today as it moves across Arizona through early Friday. Expect 
scattered showers and thunderstorms into this evening before 
activity ends from west to east overnight. Drier air behind the low 
will limit thunderstorms to mainly east and south of Tucson Friday 
and through the weekend. After a couple of cooler than normal days 
high temperatures will warm back up to normal over the weekend. 


&& 


Discussion...closed upper low off Southern California coast this morning 
has tapped into some middle to high level moisture from the outer edges 
of Tropical Storm Lowell and spread it north across western Arizona. 
The Yuma Doppler radar at 230 am showed a few light showers over the 
northern Gulf of California...near Rocky Point and south of 
Lukeville. Precipitable water values this morning were around 1.30" 
areawide with models suggesting that these values will rise into 
1.50"-1.60" range this afternoon. This closed upper low will slowly 
dig S this morning before making the turn east into northern Baja California 
California. Expect scattered showers to develop west of Tucson this 
morning and slowly spread/develop across the remainder of the 
forecast area this afternoon into this evening. Not going overly 
wild on quantitative precipitation forecast values...mostly less than a quarter of an inch...but 
could see some localized 1" rain amounts where storms get some more 
sun. Can't rule out that a storm or two will getting pretty strong 
either with wind gusts up to 50 miles per hour. With the cloud cover and 
showers...high today will remain below normal with some locals 
running 7-10 degrees below normal...especially out west. Overall 
this is not your typical August monsoon day. 


This closed low opens up this evening as it moves into SW Arizona and 
continues to lift NE across the state overnight into Friday morning. 
Scattered storms continuing across most of the area this evening 
before drier air punches into western areas and moves across the 
area overnight. Thus expect storms to end from west to east. 


Upper trough axis over the eastern areas Friday afternoon. Although precipitable water 
values will be down versus today...still will see isolated to 
scattered storms Friday afternoon. Highs warmer than today but still 
below normal. 


Low grade monsoon forecast for the weekend as an upper trough passing 
by to the north keeps drier westerly flow over the area. However 
will have enough residual moisture for slight chance of storms 
mainly south and east of Tucson. Warmer with highs slightly above 
normal both days. 


Next week...with uncertainty on amount of tropical moisture being 
sent our way from the next Pacific tropical storm...went with basic 
climatology probability of precipitation areawide. Models are suggesting that we could see light 
southerly winds moving up the Gulf of California as early as Sunday 
with stronger winds on Monday which will bring Gulf surge likely 
Monday night into Tuesday. Highs will remain slightly above normal. 


&& 


Aviation...valid through 22/12z. 
Broken-overcast clouds mainly above 12k feet above ground level through 21/15z...then scattered-broken 
clouds at 6-10k feet above ground level and broken-overcast clouds at or above 12k feet above ground level. Isolated-scattered 
showers and thunderstorms developing during the middle morning hours 
and persisting through tonight. Precipitation chances will be highest 
west of a kols to ktus to kcgz line this morning through the middle 
afternoon hours...and then east of this line late this afternoon and 
tonight. MVFR visibilities and wind gusts to 45 kts will be possible 
with the stronger thunderstorms and rain. Outside of thunderstorm outflows...surface 
wind will generally be less than 10 kts. Aviation discussion not 
updated for taf amendments. 


&& 


Fire weather...isolated to scattered showers and thunderstorms are 
expected through early next week. The stronger thunderstorms will 
produce strong...gusty and erratic winds. Outside of thunderstorm 
outflows...20-foot winds will exhibit normal diurnal trends and will 
be mostly less than 15 miles per hour.
