NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
825 PM MST Tuesday Nov 25 2014 


Synopsis... 
dry air will continue to overspread the area...resulting in mostly 
clear skies and temperatures near normal through Wednesday. 
Afternoon temperatures will peak in the upper 70s/lower 80s toward 
the end of the week as a strengthening high pressure ridge positions 
itself over the Desert Southwest. 


&& 


Discussion... 
strong ridging was building east into the forecast area region this 
evening per WV imagery. Clear skies and a weak pressure gradient 
providing light winds were allowing temperatures to fall fairly 
quickly in a dry environment. For the most part...the forecast had 
accounted for this and only made minor 1f-3f hourly and forecast low 
temperatures adjustments based on current trends. Otherwise...no 
major changes were needed in the evening update. 


&& 


Previous discussion... 
/205 PM MST Tuesday Nov 25 2014/ 
latest streamline analysis shows a broad anticyclone across the 
eastern Pacific producing a dry subsident northwesterly flow across 
the Desert Southwest. Standardized anomalies associated with the 
ridge off the West Coast are on the order of 1 to 3 above the mean. 
Meanwhile...surface dewpoints have dropped into the single digits 
and even below zero in some spots across the Phoenix area. 


Tonight...light winds and clear skies will beget optimal radiational 
cooling conditions. Below normal temperatures are expected with 
readings as low as the upper 30s across the southeast valley and 
even a few degrees cooler into Pinal County. Forecast was weighted 
towards a consensus of the bias-corrected MOS values...which 
traditionally does quite well in these scenarios. 


Models remain in excellent agreement depicting a warming trend 
through Thanksgiving as the ridge slides eastward. European model (ecmwf) has been a 
top performer recently for maximum temperature and the forecast high in 
Phoenix was raised to 82 degrees for Thanksgiving...a few degrees 
shy of the record of 86 degrees last set in 1950. 


The vast majority of the upcoming forecast will feature dry weather 
with above normal temperatures. Looking ahead for middle 
week...Thanksgiving...and into the weekend...a ridge off the West 
Coast will gradually move inland and position itself over Arizona 
Thursday/Friday. This will result in gradually increasing 
temperatures...peaking around 80 across the lower deserts Thursday 
and Friday...possibly Saturday as well as heights and 925mb temperatures 
remain virtually unchanged during this period. Overall very quiet 
weather with no chance of precipitation. 


Attention turns toward a large upper low which will move through 
northern California on Sunday and into Nevada/Utah/Arizona early 
next week. Operational models and ensembles are beginning to 
converge on a solution of precipitation developing at some point Monday 
across southeast California as moisture convergence and isentropic 
ascent strengthens east of the coastal mountains. Today\s 00z GFS is 
a bit faster and more progressive with the trough compared to the 
European model (ecmwf). Ensembles seem to favor a slightly slower arrival per the 
European model (ecmwf) solution. I introduced 20-30 probability of precipitation across portions of the area 
as early as Monday across southeast California...and across Arizona 
Monday evening/Tuesday. Biggest uncertainty at this point is timing 
when the precipitation will arrive. Could also see snow levels fall quite a 
bit behind the low although at this point impacts appear to be 
minimal in our higher terrain locales. 


&& 


Aviation... 
south-central Arizona including kphx...kiwa...and ksdl...and 
southeast California and southwest Arizona...including kipl and 
kblh... 
no significant aviation concerns through Wednesday evening under 
clear skies. Slantwise visibilities could be once again be reduced 
by smoke during the late night/early morning hours west of kphx. 
Otherwise...winds will be unusually light under 8 knots...and in many 
cases calm or variable for prolonged periods. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Thursday through Monday... 
strong high pressure will affect the Desert Southwest Thursday and 
Friday...for well above seasonal normal high temperatures. High 
temperatures both days will climb into the low 80s over the warmest 
lower deserts.A subtle cooling trend is anticipated over the weekend 
as the high gradually weakens...but high temperatures will remain 
well above seasonal normals. Humidity values will be low through 
Saturday...with most of the deserts mostly in the teens. Humidity 
levels will climb Sunday into Monday as a Pacific low pressure 
system starts to move inland and into the area from the west. By 
Monday...expect a slight chance of showers from the central Arizona 
deserts westward. Overnight recoveries will be fair to good...slowly 
improving each night with most of the deserts reaching between 40 
and 50 percent over the weekend. Winds will be on the light side 
each day through Sunday with only minor afternoon gustiness. 
Increased southerly to southwesterly breeziness is expected Monday 
ahead of the approaching weather system.
