NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Phoenix Arizona 
800 PM MST Thursday Jul 24 2014 


Synopsis... 
strong high pressure will hold over The Four Corners...resulting in 
some of our warmest temperatures so far this year. Sufficient 
monsoonal moisture will be around the region to support afternoon and 
evening storm chances through the middle of the coming week...with 
the best focus for storms likely over the higher terrain of south- 
central Arizona. Daytime temperatures will still hold above seasonal 
normals...but should fall back from near-record readings. 


&& 


Discussion... 
fairly quiet night across the area this afternoon/evening...as the 
only area that saw convection was La Paz and Yuma counties. There 
are still a few storms across portions of La Paz County where 
MLCAPES are still hovering around 500 j/kg...but this is rapidly 
eroding with the loss of daytime heating. The rest of the area 
remains very stable. To the east...a couple of outflows are making 
their way through the Phoenix area this evening but there\s no 
suggestion of significant blowing dust with any of them. Looks to be 
more of a brief wind shift than anything. 


Quick update to allow the excessive heat warning to expire at 8 PM 
as scheduled. After back to back days of record tying or record 
breaking temperatures for the Phoenix and Yuma areas...slightly 
lower temperatures still look on track for the region Friday through 
the weekend. A look at the available 00z model data suggests probability of precipitation 
are in good shape for the rest of the night /a few isolated showers 
along the lower Colorado River valley/. Aside from minor adjustments 
to temperatures/dewpoints based on observed trends...forecast is in good 
shape. 


&& 


Previous discussion... 
the deepest monsoon moisture surface has transitioned through central 
Arizona through the day and has settled over the western third of Arizona and 
along the Colorado River valley this afternoon. Mostly clear morning skies 
across the southeastern corner of Arizona are now dotted with small 
cumulus...indicating the anticipated low and middle level drying continues 
and stabilizing of the atmosphere continues. Surface dewpoints 
indicate the most favorable monsoon moisture boundary is now across 
western Arizona...where there are still some pockets of 60 degree 
dewpoints. In addition...subtle upper level dynamics in the form of 
an upper jet streak across southern Nevada and central Utah will help focus 
activity in a line along the western fringes of the Phoenix metropolitan 
south towards Gila Bend and towards the Colorado River valley...including 
Blythe and Yuma...for the rest of the evening. 


Still anticipating somewhat cooler temperatures Friday and into 
Saturday as the upper high...currently to our east over nm...weakens 
slightly by a dm or two. In addition...low level moisture values will 
likely be on the increase as some extent of Gulf of California 
moisture will work its way into portions of the Lower Desert 
elevations. A strong outflow boundary from convection near the Baja California 
tip has been observed on surface observation and satellite data and will continue 
to work northward. By Friday am...850mb dewpoints could return to 10c 
to 12c and expect debris clouds from tonight's activity to linger 
longer into the day. This infusion of moisture will support at least 
slight storm chances across much of the forecast area for Friday. 


A better threat for afternoon and evening convection 
is expected on Saturday as the upper high center shifts a little 
further east...allowing a deeper southeasterly flow to develop over 
the region...importing more moisture into the Desert Southwest. 
Another weak shortwave embedded in this flow appears that it will 
move into the region...further enhancing the convective activity as 
MUCAPES are pushed up into the 500-1000 j/kg range. 


Sunday through Thursday... 
it appears that a low-middle grade monsoon 
will likely prevail through the extended period as weak southerly 
flow aloft continues to pull moisture into the region...but with the 
upper high center attempting to reposition itself westward back over 
the region...stabilizing the airmass somewhat and perhaps putting a 
bit of a lid on the convective activity. 


&& 


Climate... 
record high temperature for the middle of the week.

Phoenix 116 in 2014 115 in 1943 
Yuma 117 in 2014/1943 120 in 1943

Aviation... 
south-central Arizona including kphx...kiwa...and ksdl... 
going to have to contend with a few outflows for the rest of the 
evening across the metropolitan...but not looking at any new storm 
development. Storms appear more likely on Friday but for now...will 
keep any mention out of the tafs until timing/coverage can be pinned 
down. 


Southeast California and southwest Arizona including kipl and kblh... 
a few showers remain just to the east of Blythe but they are quickly 
dissipating as of 03z. Both terminals should remain dry for the rest 
of the night. Only some debris clouds to contend with at either southeast 
California taf site. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Sunday through Thursday... 
slightly cooler afternoon temperatures are expected along with 
higher humidity. Minimum relative humidity levels will range from 15 
to 25 percent. A typical monsoon daily threat of afternoon and 
evening thunderstorms are expected with the highest probabilities in 
the mountains east of Phoenix. Typical afternoon and evening 
southwest winds are expected with good recovery at night. 


&& 


Psr watches/warnings/advisories... 


Arizona...none. 


California...none.
