NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
900 PM MST Sat Apr 25 2015 


Synopsis... 
a strong cold front will move through the region early tonight 
bringing gusty winds and good chances for rain. Chances for 
showers and thunderstorms will increase this evening and into 
tonight...but mainly across portions of southwest and south central 
Arizona. Lingering showers are expected Sunday over eastern 
Arizona...with clearing over southeast California and southwest 
Arizona. Drier and much warmer weather is expected next week. 


&& 


Discussion... 


..potent upper trough and frontal passage across the region tonight 
with strong gusty winds and thunderstorm chances... 


Vigorous Middle Spring Pacific storm system continued to move eastward 
across the Desert Southwest early this evening...bringing scattered 
to numerous showers as well as embedded thunderstorms to the state. 
00z plot data showed the largest 500 mb height falls across northwestern Arizona 
and far southern Nevada...with 70m falls near Las Vegas. Coldest 
air...near the center of the low...was well to our north and 
northwest...with readings down to minus 22c at 500mb over far southern 
Nevada/far northwestern Arizona. Correspondingly the most significant convection 
has stayed to our north...although at 8 PM a cluster of somewhat 
weak storms were seen moving through portions of La Paz 
County...approaching northwest Maricopa County. Infrared imagery at 8 PM 
showed generally cloudy skies over most of Arizona with partial 
clearing taking place west of the lower Colorado River valley. 


Guidance remains consistent in calling for the storm to dive 
southeastward across Arizona tonight...bringing some of the best 
forcing to central Arizona by 12z Sunday. A large bullseye of middle level q 
convergence and strong positive vorticity advection focus into Maricopa County after midnight 
tonight and there appears to be sufficient moisture to allow for 
numerous showers forming over the central deserts starting later 
this evening and persisting well past midnight. Despite somewhat 
limited cape values...there is enough forcing and a strong enough 
upper wind field to allow isolated storms to form tonight...and any 
storm that forms has the potential to produce gusty winds in excess 
of 40 miles per hour as well as smaller hail and brief moderate to heavy rain. 
By sunrise Sunday...clearing will taking place west of Maricopa 
County as stronger subsidence behind the passing trough moves into the 
area. Strong and gusty west winds continued over portions of 
Imperial and eastern Riverside County early this evening...with 
occasional gusts reaching to near or slightly above Wind Advisory 
levels. Expect the winds to gradually taper off and for the most 
part should drop below criteria by the time the advisory ends at 9 
PM. Forecasts have been adjusted for current sky...pop and weather 
trends and appears to be in good shape for now. 


Previous discussion... 
today thus far has been fairly quiet across the area except for some 
light showers passing through Riverside and La Paz counties with 
some recent development just to our north in Yavapai County. These 
showers were in response to a weakening shortwave trough moving into 
central Arizona out ahead of the main trough that will affect the 
area later today and tonight. Current water vapor and upper height 
analysis shows a rather impressive upper trough approaching from the 
northwest with the main shortwave trough just west of Las Vegas. 
Difluent flow aloft over southern Nevada and Utah along with strong 
500mb height falls centered over the sierras are helping to spark 
off scattered showers and thunderstorms. Winds ahead of an advancing 
cold front have become gusty across southeast California with some 
gusts to around 35 knots. As the front moves through this 
evening...can expect some wind gusts up to 40-45 knots in some 
localized spots along with the potential for some blowing dust. 


The main shortwave trough and cold front will quickly dive 
southeastward through the rest of today...reaching south-central 
Arizona around 06z this evening. Still expecting scattered to 
widespread showers and thunderstorms to develop ahead of these 
features during the evening time frame with best chances stretching 
from northern La Paz County through much of Maricopa County...into 
southern Gila County. Conditions remain rather moist between 8-10k 
feet...but further moistening in the middle levels will occur as the 
trough and colder air moves in from the northwest. The moist 
conditions...weak upslope low level flow...and strong forecast model 
Omega for this evening across south-central Arizona...will all come 
into play to aid in shower and thunderstorm development. Stronger 
showers or thunderstorms will have the potential to bring some gusty 
winds down to the surface...so some stronger sub-severe gusts are 
possible. 


By Sunday morning...the main shortwave trough will be moving into 
western New Mexico with subsidence aloft working into our western 
zones. Chances for lingering showers will be possible through Sunday 
morning from around Phoenix eastward with best chances over the 
higher terrain of east-central Arizona. By middle to late Sunday 
afternoon...the drier air behind the trough will have mixed out the 
low levels enough to basically keep any remaining shower chances 
over higher terrain areas. Our western zones should clear out fairly 
quickly on Sunday with highs rebounding back into the low to middle 
80s. Elsewhere...temperatures should only peak out in the upper 70s 
across the south-central Arizona deserts. 


For the coming work week...a large ridge is forecast to take over 
with dry conditions and warming temperatures. Highs by Monday should 
reach near normals and once the upper level ridge finally takes 
over...temperatures will heat up even more with forecast highs in 
the middle to upper 90s for Wednesday and Thursday across the 
deserts. Though there are some model differences beyond next 
Thursday...the general consensus is that large scale troughing will 
push the ridge out the region allowing for some moderation in 
temperatures...but continuing with the dry conditions. 


&& 


Aviation... 


South-central Arizona including kphx...kiwa...and ksdl... vigorous 
upper level Pacific storm system continued to approach the central 
deserts early this evening...but as of 8 PM most ceilings were at or above 8k 
feet and showers were isolated to scattered. Still expect ceilings to 
lower and showers to becoming more widespread by 05z...with ceilings 
below 5k feet likely after midnight and through sunrise Sunday. 
Isolated embedded thunderstorms area also possible...but confidence 
not high enough to call for predominate thunder. Have gone with 
predominate showers in the Phoenix area tafs after 05z...with thunderstorms in the vicinity 
added to reflect the thunder threat. Should a storm form the surface 
winds may become rather strong and gusty and variable for brief 
periods but winds should favor the west overnight tonight. Overnight 
tonight winds will taper off but may be hard pressed to show normal 
diurnal tendencies...and may not turn to the east. Precipitation should be 
mostly over by middle morning Sunday...with lingering lower clouds and 
some broken decks possible through the afternoon hours...with ceilings 
in the 5k to 7k range. Gusty west/northwest winds should develop 
again by early afternoon. 


Southeast California and southwest Arizona including kipl and 
kblh...main weather issue in the tafs will be gusty west winds 
tonight...and we may see occasional gusts over 30kt through 05z or 
so before they start to taper off. For the most part expect visible 
values at or above 6sm for the rest of tonight as winds slowly taper off. 
May see a few ceilings around 8-10k feet at kblh through midnight with a 
shower possible...but then clearing will occur as the main trough 
exits to the east. Low level wind shear is possible at kblh after midnight as 
surface winds taper off below 12kt...but 35kt northwest winds set up 
just above the surface. Have mentioned this in the kblh taf. Expect 
a return to gusty northwest/north winds down the river Sunday with 
occasional gusts above 25kt possible. Breezy west winds will also 
occur at kipl Sunday...under mostly sunny skies. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Monday through Friday... 
in the wake of the departing trough...next week will see the arrival 
of a strong upper ridge over the southwestern Continental U.S. From Monday 
through most of the week. Temperatures will warm substantially and 
approach the triple digit mark for the latter part of the week. 
Afternoon humidities will drop into the lower teens and upper single 
digits with fair overnight recoveries expected. Winds will be gnly 
light and should follow typical diurnal patterns.
