NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
257 PM MST Monday Oct 20 2014 


Synopsis... 
gradual drying will occur this week...but there will again be 
slight chances for showers and thunderstorms across the mountains 
north and east of Phoenix through early evening. Some warming is 
expected by middle week into the weekend with temperatures several 
degrees above normal as high pressure settles overhead. 


&& 


Discussion... 
isolated convection continues across eastern Arizona this afternoon 
but is already much less vigorous than this time Sunday...and also 
much less widespread. MLCAPES are also significantly less today 
across the deserts compared to yesterday with values less than 100 
j/kg across the Phoenix area and around 0 across Yuma el centro. 
Finally...temperatures are also lower today with readings in the middle 
80s compared to middle 90s yesterday. 


All of these factors are shaping up to make this afternoon and 
evening much quieter than yesterday. Nonetheless with convection 
ongoing across portions of the state...I will hold short of saying 
nothing is going to happen this evening. I will retain the 20-30 
probability of precipitation for portions of Gila County and keep some upper single digits 
across the metropolitan area...otherwise areas to the west will be dry 
tonight. 


Meanwhile a deepening upper low over the Pacific northwest will continue to 
move inland overnight and through Utah on Tuesday. Strong 
southwesterly flow aloft ahead of this trough will bring about the 
end of our monsoon-like pattern and re-Orient the best storm chances 
well North/East of Phoenix. Best chances of showers will actually be 
in Utah but there's certainly a non-zero chance of precipitation across the 
mountains east of Phoenix given modest isentropic forcing. Not 
expecting a big event whatsoever...a few mountain showers should be 
all about we see with this trough along with some increasing high 
clouds. 


Lingering moisture on Tuesday should still allow for a few isolated 
showers or thunderstorms across eastern Gila County...but the 
gradual drying will eventually take away any threat of afternoon 
convection by Thursday. The Desert Southwest will stay well south of 
the main Pacific jet stream this week while a strong Pacific Ridge 
eventually shifts eastward over the region by Thursday into the 
weekend. 500mb heights will build to near 588dm late this week 
providing for a warming trend during the period. Forecast highs will 
likely move into the middle 90s across the lower deserts of 
southeast California and southwest Arizona for Thursday through 
Saturday. A slight cooldown is probable starting either Sunday or 
next Monday as the ridge is shown to break down and broad scale 
troughing shifts southward into the southwestern United States. The 
dry weather starting by late this week is expected to persist into 
early next week.

Aviation... 
south-central Arizona including kphx...kiwa and ksdl...southeast 
California and southwest Arizona including kipl and kblh... 


Through 18z Tuesday...mostly clear skies. Light wind under 8 knots. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Thursday through Monday... 
strong high pressure centered over Arizona will remain in place 
through Friday but will gradually break down this weekend into next 
week as a trough moves inland and sweeps through the Great Basin. 
Afternoon humidities will drop into the upper single digits each 
afternoon with fair overnight recoveries expected. Humidities will 
increase somewhat ahead of the trough since temperatures will be 
slightly cooler. At this point it doesn't appear there will be any 
major wind events with this trough but there could be some enhanced 
breeziness down the lower Colorado River Sunday/Monday. 


&& 


Psr watches/warnings/advisories... 


Arizona...none. 


California...none.
