Area Forecast Discussion
National Weather Service Phoenix AZ
1030 PM MST Mon Feb 27 2023
.UPDATE...Updated 06z Aviation Discussion.
&&
.SYNOPSIS...
Dry conditions and below normal temperatures are expected today
as lower desert highs range from the low to mid 60s this
afternoon. Temperatures will remain below normal for the next
several days, before a warming trend begins this weekend allowing
temperatures to moderate. Before that, a weather system will move
through the region Wednesday and Thursday. Windy conditions are
likely Wednesday ahead of the system. Precipitation is also
anticipated as this system passes by, particularly north and east
of Phoenix. Given the cold air, accumulating snow will be possible
down to 3000 feet.
&&
.DISCUSSION...
Dry conditions, light winds, and passing clouds are expected across
the Phoenix metro today. South-central AZ will have highs in the low
to mid 60s this afternoon, while southeast CA/southwest AZ will
reach the mid 60s. Temperatures will remain below normal across the
CWA through Friday and slightly dip another couple degrees by mid
week. Elevated flow in Tonto Creek will continue through Friday as
well. Water vapor imagery this morning shows west/southwest zonal
flow across the region today, ahead of a deepening trough along the
west coast set for Wednesday-Thursday. This next weather system has
the potential to bring precipitation and breezy to windy conditions
to our forecast area.
As the cold low pressure system begins to track across the west,
ensemble members show good agreement that it will arrive by
Wednesday. GEFS depicts that the trough will linger on Thursday,
while EPS and CMCE favor a faster progression with more amplified
ridging. With the approach and passage of this system, windy
conditions and blowing dust are expected to develop. The ECMWF
Extreme Forecast Index shows values of 0.8+ over portions of our
region, with the highest values (wind gusts values up to 0.9+)
depicted over southeast CA/southwest AZ. This indicates that this
has the potential to be an anomalously strong wind event for
mainly the western portion of the CWA, which will justify the
issuance of Wind Advisories in the near future. A High Wind Watch
has been issued for parts of Imperial County on Wednesday, given
that NBM probabilities have up to a 30% chance of reaching 60+ mph
winds.
Just ahead of and with the frontal passage, precipitation can be
expected over the region. The best chance for rainfall currently
remains over the AZ portion of the CWA in the Wednesday night into
Thursday morning time frame. NAEFS IVT values reach above 300
kg/m/s, indicating that there will be sufficient enough moisture
flux and isentropic lift to develop precipitation. ECMWF and GEFS
PWAT values are generally above 0.5", further proving there will
be enough available moisture to pull from. NBM QPF is at around
0.25" for south-central AZ and up to 0.8" for higher elevations,
while southeast CA/southwest AZ will range from zero to 0.15" near
Joshua Tree NP. 12-hr PoPs range from 50-70% across the Phoenix
metro area.
This system is also likely to produce low elevation accumulating
snow. The Extreme Forecast Index shows that this will be an unusual
snow event for this time of year, specifically for lower elevations.
Due to this, a Winter Storm Watch has been issued from Wednesday
morning through early Thursday morning for elevations above 3500
feet. This will impact the Mazatal, Pinal, and Superstition
Mountains and areas in Gila County like Globe and Miami. Snow levels
have the potential to fall lower as well, with snow around 3000 ft
possible. Expect difficult travel conditions due to slippery roads.
As we head into the weekend, weak ridging will build over the region
following the departure of this system on Thursday. Along the west
coast, a trough will begin to build but the lowest heights appear to
be far enough north to leave our CWA in modest southeasterly
flow. A warming trend is anticipated to begin by Saturday, as
temperatures moderate to seasonal normals through early next week.
&&
.AVIATION...Updated at 0530Z.
South-Central Arizona including KPHX, KIWA, KSDL, and KDVT:
No aviation weather concerns are expected through the TAF period.
Diurnal winds with a ESE component through tonight. West winds
increase heading into Tuesday afternoon with sustained speeds
upwards of 10-15 kts. Otherwise, mostly clear skies will persist
through tomorrow morning before SCT decks around 6 kft are
expected to develop tomorrow afternoon.
Southeast California/Southwest Arizona including KIPL and KBLH:
Winds through the next 24 hours will favor the W at KIPL and SW at
KBLH. Any lingering gusts will taper off over the next couple of
hours, though elevated speeds around 10 kts will continue. Gusty
winds will develop late morning to early afternoon tomorrow at
both terminals. Otherwise, mostly clear skies with periodic SCT
mid-level clouds during the afternoon and evening hours.
&&
.FIRE WEATHER...
Steady temperatures and humidity levels through tomorrow with just
a touch of afternoon breeziness. The next chance for wetting
rains arrives Wednesday primarily focused into Arizona. Humidity
levels will increase ahead of this system then drop quite a bit
behind it on Thursday. Widespread windy conditions are likely
Wednesday. The lower humidity values will carry into next weekend
along with slowly warming temperatures and lighter winds.
