Area Forecast Discussion
National Weather Service Phoenix AZ
1055 PM MST Fri Jun 24 2022

.UPDATE...
Updated 06Z Aviation

.SYNOPSIS...
Moisture will hang around with an even more favorable monsoon
pattern setting up Sunday into next week. Today and tomorrow, winds
and blowing dust will be the main weather risks, especially along I-
8 and I-10 in Maricopa, Pinal, and Yuma counties. Sunday and Monday,
the flooding potential increases across the lower deserts as more
moisture from soon to be Hurricane Celia advances towards the
region. Low to moderate HeatRisk remains in place through next week.

&&

.DISCUSSION...
This morning, the 12Z sounding at Phoenix and Yuma, showed 1.37
inches and 1.23 inches of precipitable water respectively. This is a
lot of moisture for this time of year with both of these values
exceeding the daily maximum according to sounding climatology. The
synoptic pattern remains nearly the same today, with slightly more
westerly flow. An unstable atmosphere will be in place again today
with mesoanalysis depicting MLCape values rising into the 500-1000
J/kg range across much of Maricopa, Pinal, and La Paz counties this
afternoon. In these areas, DCape values will also be extremely high,
in the 1800-2000 J/kg range.

Convection will continue to develop across northern and eastern
Arizona this afternoon, including southern Gila County, and be a
little delayed across southern AZ (compared to yesterday). There is
also a chance for lower desert storms, with a ~25% chance in the
Wickenburg area, ~20% chance across the Phoenix and Casa Grande
area, and <10% chance in Parker and Quartzite areas. Strong
downburst/outflow winds and blowing dust will be the biggest risks
today, especially along I-8 and I-10 in Maricopa and Pinal counties.
The HREF probability of wind speeds exceeding 35 mph today is
greater than 70% in southern Gila county, 50-70% in Maricopa and
Pinal counties and 30-50% in La Paz county. Most areas will likely
see less than a quarter inch of rain with storms. However, with
plenty of moisture in the atmosphere to tap into, some cells may
produce upwards of 0.5-1.0 inch of rain.

Tomorrow, the area of focus shifts westward into western Pima,
southern Maricopa, and Yuma counties, as this is where the best
instability will be. The probability of greater than 35 mph wind
speeds in this area is greater than 50%. HRRR 80m wind is also
showing a decent outflow boundary developing and traveling northwest
and potentially moving through southeast California. Strong
downburst/outflow winds and blowing dust will be the biggest risks
tomorrow in these areas, especially along I-8 in Yuma, Maricopa, and
Pinal counties.

We are still expecting a more favorable monsoon pattern to set up
Sunday and last much of next week. It also appears that Sunday into
Tuesday, we will see an increase in moisture from the tropics,
thanks to soon to be Hurricane Celia. Thunderstorm chances in the
Phoenix area rise to 25% each day Sunday into next week. Heavy rain,
strong winds, and blowing dust will be the main risks each day.
Moderate HeatRisk will remain in place for the lower deserts of our
CWA through at least early next week.

&&

.AVIATION...Updated at 0555Z.

South-Central Arizona including KPHX, KIWA, KSDL, and KDVT:
Erratic winds from an isolated thunderstorm in the Chandler area to
produce erratic winds for the next hour or so at KIWA and KPHX, with
KIWA having the greatest risk for strong winds being at KIWA. There
is a lesser chance for TS impacts at KSDL and KDVT, with winds at
both these terminals remaining mainly from a northerly direction for
the next hour or so. More typical easterly drainage winds return
later this evening/overnight as the shower/TS activity diminishes.
As far as Saturday is concerned, after light easterly winds in the
morning, the typical westerly switch is expected to occur around
midday/early afternoon. Winds are expected to become rather gusty by
late afternoon as more showers/T-storms develop, mainly to the
south/southwest of the Phoenix metro. Outflows from these storms
could briefly produce (50-70% chance) of winds gusts aoa
35kts/blowing dust by late afternoon, with even a 20-30% chance that
a thunderstorm will directly impact one (or more) of the terminals.
However, confidence is still too low at this point to include
anything more than VCSH in the TAFs at this point. Convective
activity is likely to diminish rather rapidly by mid-evening
Saturday with winds likely switching to a southeasterly direction.

Southeast California/Southwest Arizona including KIPL and KBLH:
Little to no weather concerns will exist through Saturday evening
under clear skies. Current southwesterly winds to become light
southerly to southeasterly by late tonight/early Sat morning. A bit
stronger winds can be anticipated by Saturday afternoon.

&&

.FIRE WEATHER...
Moisture will remain entrenched across the desert southwest through
next week. There will be daily opportunities for afternoon and early
evening shower and thunderstorm activity, especially across Arizona
and high terrain locations. With the increased moisture, MinRH
values will remain above 15% across most areas through tomorrow and
above 20% Sunday into all of next week. Great overnight recoveries.
Apart from frequent late afternoon/early evening thunderstorm
downburst and/or outflow winds, no other significant winds are
expected.

&&

.PSR WATCHES/WARNINGS/ADVISORIES...
AZ...None.
CA...None.
