National Weather Service Phoenix AZ
426 AM MST SUN OCT 7 2018
The National Weather Service in Phoenix has issued a
* Flash Flood Warning for...
Maricopa County in south central Arizona...
* Until 800 AM MST.
* At 425 AM MST, Doppler radar indicated thunderstorms producing
heavy rain across the warned area. Up to one inch of rain has
already fallen near Gila Bend. Flash flooding is expected to begin
shortly along Highway 238 east of Gila Bend.
* Some locations that will experience flooding include...
Gila Bend, Estrella, Bosque, Sonoran National Monument and Mobile.
* This includes the following highways...
AZ Route 238 between mile markers 1 and 35.
AZ Route 85 between mile markers 121 and 123.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.
Be especially cautious at night when it is harder to recognize the
dangers of flooding.
In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to cross flooded
roads. Find an alternate route.

Area Forecast Discussion
National Weather Service Phoenix AZ
158 AM MST Sun Oct 7 2018
.SYNOPSIS...
A Pacific weather system will bring good chances for showers and
thunderstorms over central and eastern portions of Arizona today
with lingering chances into Monday. Cooler temperatures are
expected behind this system with afternoon highs struggling to get
out of the 70s through Tuesday. Temperatures will remain below
normal for all of next week with precipitation chances returning
late Thursday and Friday as remnants of Hurricane Sergio possibly
affects our area.
&&
.DISCUSSION...
An unseasonably strong upper level trough of low pressure is
currently digging down the West Coast this morning and is aided by a
120 kt northerly jet (at 250 mb) that extends from Washington
down through Northern California. This trough can clearly be seen
in water vapor imagery with thunderstorms firing off along a
trailing surface cold front. As expected, storm motion has been
parallel to the front early this morning which has caused some
training of storms and nuisance flooding in northern La Paz and
Maricopa Counties. We are expecting this sort of training to
continue throughout the morning which could bring flash flooding
to localized areas, especially those places in favorable upslope
flow. Subsequently we will continue the Flash Flood Watch for
northern Maricopa and portions of Gila County. Finally, a large
amount of shear exists along this front which will create an
environment conducive to rotating storms. This could produce
severe storms and perhaps a brief funnel cloud on the northern
edge of our CWA but given the time of day, expecting this to be
isolated.
The aforementioned front will continue to progress eastward today
and will push through the Phoenix metro between 9 and 13 UTC and
into Gila County by late morning. The best precipitation chances
today will be associated with this front although post frontal
showers will bring another shot of precipitation to south-central
Arizona this afternoon. Additionally, cooler air will filter in
behind this front bringing high temperatures down into the 70s
this afternoon for the lower elevations of south-central Arizona
with 80s in SE California.
This trough will be slow to exit our area which means showers and
storms, mainly for the higher elevations, will linger into Monday.
A gradual warming trend is then forecast for Tuesday and Wednesday
as the trough kicks out and the airmass modifies under the early
October sun. Despite the warming, daytime highs and overnight
lows will still be 5 to 10 degrees below average.
Much uncertainty exists for Thursday and Friday as the remnants of
what is currently Hurricane Sergio moves towards our area. Latest
ensembles still track the remnants through far southeast Arizona
but matters are complicated as the moisture interacts with a
trough passing by late next week. Over the past several days the
GEFS has significantly trended down on precipitation amounts over
Phoenix with only a quarter of an inch falling over the metro
Thursday and Friday with even less over Yuma. However, a shift in
the track, notably to the north, would bring substantially more
rain and a widespread flash flooding risk. At this point, it is
still too early to discount widespread impacts over our CWA from
this passing tropical system but chances are becoming less likely
with each passing model run. For now, please stay tuned to the
forecast as we iron out the details which will hopefully become
more clear in the coming days.

.AVIATION...
South-Central Arizona including KPHX, KIWA, and KSDL:
No significant aviation issues through at least midnight; winds to
stay mostly southwest with a few evening gusts into the teens. FEW-
SCT cumulus as well as cirrus decks. Big issues arrive after
midnight however as...
Strong cold front will be swinging through the greater Phoenix area
during the early morning hours Sunday. Best window for strong wind
gusts as well as thunderstorms likely to be 10z through 14z. Expect
widespread showers during this period, some with moderate to heavy
rain. A few storms may be severe. CIGS should mostly stay 5k-8k but
locally could drop to around 3k in stronger storms or heavier
showers. Visibility could also drop to 3SM or below but briefly as a
stronger storm or heavy shower moves through. Due to lack of
confidence and long time range, have opted not to lower CIGs or VIS
overly much with the evening TAF package, but potential is there for
some significant restrictions at times during the frontal passage
window. Winds should initially back to the southeast and become
gusty (after 09z or so) then swing to the southwest between 11z and
12z as front moves through with gusts to near 30kt possible.
After front moves through (after 14-15z) expect considerable
lingering SCT-BKN cumulus with 4-6k bases as well as lingering
instability showers into the early afternoon. Wind to stay west
through the afternoon with a few higher gusts into the teens at
least.
Southeast California/Southwest Arizona including KIPL and KBLH:
Very breezy to windy southwesterly to westerly winds are expected at
KIPL near 12-19kt with gusts to 20-27kt through the late evening
hours. Breezy southwesterly winds at KBLH through this evening are
expected to become northwesterly by late tonight near 12-15kt. Skies
will be partly cloudy with FEW-SCT decks from 8-9kft and
occasionally BKN high cloud decks. By mid-day Sunday expect winds
mostly northwest to north; At KBLH we should see north winds gusting
over 20kt after 18z.
Aviation Discussion not updated for amended TAFs.
&&
.FIRE WEATHER...
Tuesday through Saturday:
Expect below normal temperatures and few fire weather concerns
through the period. Drier conditions on Tuesday will be replaced
by an increasing moisture trend starting Wednesday. Remnants of
what is currently Hurricane Rosa will bring an elevated chance of
precipitation Thursday afternoon through Friday but the track is
still somewhat uncertain. Currently, Pinal and southern Gila
Counties have about a 50% shot at seeing a wetting rain with much
lower chances elsewhere. Throughout the period winds will be
rather light with the exception of some breezes in southeast
California during Wednesday and Friday afternoon.
