NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
440 am MST Monday Apr 21 2014 


..updated aviation and fire weather... 


Synopsis... 
high pressure will build into the area early this week leading to 
sunny days...clear nights...and sharply warmer afternoon high 
temperatures. Breezy to windy conditions will develop over much of 
the area Tuesday afternoon into Wednesday as a dry weather system 
passes to the north. Temperatures will fall only slight in response 
to this weather system...closer to seasonal normals for the 
remainder of the week. 


&& 


Discussion... 
water vapor imagery clearly shows an expanding anticyclone over 
Arizona and portions of the intermountain west...with a broad 
deepening 532dm upper level low spinning over the Gulf of Alaska 
into British Columbia. Regional upper air plots over the Desert 
Southwest have shown around a 70m increase in 500mb heights over the 
last 24 hours or so...and this will lead to additional warming for 
our forecast area today with afternoon temperatures across the lower 
deserts rising into the middle to upper 90s. With the drier nature of 
the atmosphere and plenty of sunshine...it will not be out of the 
question for some locations to flirt with the century mark for the 
first time this year. 


Operational models and numerical guidance are still in very good 
agreement with track of the upper level low over the Gulf of 
Alaska...dropping it south along the West Coast and moving an open 
wave inland into the Great Basin by Tuesday morning. The system will 
import little in the way of moisture...but middle and lower level 
pressure gradients will tighten up as the trough passes to our 
north...generating breezy to windy conditions across southeast 
California and southwest Arizona -- with sustained winds 15-25 miles per hour 
and gusts to 35 miles per hour common across our western zones Tuesday 
afternoon and evening. Some locations in and around the Imperial 
Valley/el centro California...Joshua Tree National Park...and other higher 
terrain areas in La Paz County Arizona may experience stronger winds and 
some areas of blowing dust/sand. Right now...forecast wind speeds 
are not meeting Wind Advisory criteria...but it will be something 
for future shifts to follow/monitor. 


The low level frontal passage should clear the forecast area by 
Wednesday morning...with modest height falls and cooler air helping 
drop daytime temperatures close to climatological normal Wednesday 
afternoon...mainly back into the middle to upper 80s over the lower 
deserts. Less wind is expected Wednesday however it will still be on 
the breezy side during the afternoon hours. 


Shortwave ridging commences Thursday...with 500mb heights rebounding 
to near 576dm over Southern California and Arizona by Friday. Ensemble spread 
continues to grow for the weekend time frame with each forecast 
iteration. The model trend of negative height anomalies covering the 
northeast Pacific basin remains consistent...however the subsequent 
progression of shortwaves into the western and central Continental U.S. Is 
highly uncertain. 


Operational members have retained good run to run continuity...with 
the GFS currently deepening a 541dm closed low into the southwestern 
Continental U.S. Over the weekend...while the European model (ecmwf) ejects several weaker lead 
waves through the downstream quasi-zonal flow while maintaining 
general east Pacific troughing. The operational Gem is somewhat of a 
compromise of these two extremes...but it continues to favor some 
measure of deeper troughing near the forecast area. 


Ensemble members still exhibit a vast array of possible outcomes... 
resulting in a lower forecast confidence for the weekend. At this 
time...unless the system digs even deeper west of California...any 
solution will be considerably dry with precipitation chances 
slight/slim for our forecast area. There is some agreement as to 
lower heights splayed over the region...with a tightened gradient 
somewhere in the 564dm range stretched across southeast California and 
south-central Arizona. As such...elected to drop forecast daytime 
temperatures back into the low 80s for the weekend...along with 
breezy to windy conditions again Saturday and Sunday. 


&& 


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


No significant aviation concerns through Tuesday morning as mostly 
clear skies and light winds will prevail across the region. The 
daily westerly wind shift over central Arizona should temporally 
occur similarly to yesterday (early afternoon)...however confidence 
is fairly high that the westerly component will prevail throughout 
much of the overnight. Across southeast California...a prevailing S/SW wind 
should develop though precise onset timing is slightly more 
uncertain. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Wednesday through Sunday... 
high pressure will start building into the region on 
Wednesday...however locally breezy conditions will still 
persist...particularly during the early afternoon before the 
pressure gradient relaxes by the evening. Another strong Pacific low 
pressure system will propagate into the region Friday through 
Sunday...allowing winds to strengthen...and creating another period 
of elevated fire danger. Minimum humidities will fall into the 
single digits across the lower deserts through Friday...before 
seeing a slight improvement mainly in the teens over the weekend as 
somewhat cooler weather will spread into the district.
