  lead to heat stroke.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

An Excessive Heat Warning means that a period of very hot
temperatures, even by local standards, will occur. Actions should
be taken to lessen the impact of the extreme heat.

Stay indoors and seek air-conditioned buildings. Drink water,
more than usual, and avoid dehydrating alcoholic, sugary, or
caffeinated drinks. Dress for the heat - lightweight and light-
colored clothing. Eat small meals and eat more often. Monitor
those with a higher vulnerability to heat, including small
children. Check in on family, friends, and neighbors, especially
the elderly. If engaging in outdoor activity, take longer and
more frequent breaks and avoid the hottest parts of the day.
Never leave kids or pets unattended in cars.

Public cooling shelters are available in some areas. Consult
county officials for more details, which may include guidance for
proper social distancing measures.

Recognize the signs and symptoms of heat-related illness. Early
signs include thirst and muscle cramps. Heat exhaustion may
include: cool, moist, pale skin; headache; dizziness; weakness or
exhaustion; nausea. The most serious illness is heat stroke,
which may include: vomiting; confusion; throbbing headache;
decreased alertness or loss of consciousness; high body
temperature (above 105F); hot, dry skin; rapid, weak pulse;
rapid, shallow breathing; seizures.

Heat stroke can be DEADLY. Treat as an emergency and call 9 1 1.

Continue to monitor NWS forecasts, broadcast outlets, and local
government for updates.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

An Excessive Heat Warning means that a period of very hot
temperatures, even by local standards, will occur. Actions should
be taken to lessen the impact of the extreme heat.

Stay indoors and seek air-conditioned buildings. Drink water,
more than usual, and avoid dehydrating alcoholic, sugary, or
caffeinated drinks. Dress for the heat - lightweight and light-
colored clothing. Eat small meals and eat more often. Monitor
those with a higher vulnerability to heat, including small
children. Check in on family, friends, and neighbors, especially
the elderly. If engaging in outdoor activity, take longer and
more frequent breaks and avoid the hottest parts of the day.
Never leave kids or pets unattended in cars.

Public cooling shelters are available in some areas. Consult
county officials for more details, which may include guidance for
proper social distancing measures.

Recognize the signs and symptoms of heat-related illness. Early
signs include thirst and muscle cramps. Heat exhaustion may
include: cool, moist, pale skin; headache; dizziness; weakness or
exhaustion; nausea. The most serious illness is heat stroke,
which may include: vomiting; confusion; throbbing headache;
decreased alertness or loss of consciousness; high body
temperature (above 105F); hot, dry skin; rapid, weak pulse;
rapid, shallow breathing; seizures.

Heat stroke can be DEADLY. Treat as an emergency and call 9 1 1.

Continue to monitor NWS forecasts, broadcast outlets, and local
government for updates.

.UPDATE...Updated 18Z Aviation Discussion.

.SYNOPSIS...
Increasing high pressure over the region will lead to gradual
warming into the latter half of the week with highs near normal
today before warming to around 110 degrees on Wednesday. The
hottest days are likely to be Thursday and Friday with highs of
110-113 degrees across south central Arizona and approaching 115
degrees across portions of southeast California and southwest
Arizona. Storm chances will gradually return to the higher terrain
of eastern Arizona starting Friday and potentially into the south
central Arizona lower deserts as early as the weekend. Cooler
temperatures and better rain chances look likely for next week.

&&

.DISCUSSION...
The synoptic pattern has changed very little from yesterday with
dry southwesterly flow aloft remaining over much of the Desert
Southwest. Drier air also continued to mix into the boundary
layer as some locations saw surface dew points drop into the 30s
Monday afternoon. However, we likely saw surface moisture bottom
out on Monday as models continue to show daily weak GoC moisture
surges into southern Arizona, likely boosting afternoon dew points
back into the 50s starting today.

The main forecast concern for the rest of the week will be the
decent likelihood of excessive heat across much of the lower
deserts. The subtropical high currently centered near the Ark-La-
Tex region is forecast to shift slightly westward while also
expanding westward through much of our region through mid week.
The relatively dry boundary layer (45-55 degree afternoon surface
dew points) and increasing heights aloft will lead to warming
temperatures through Thursday. NBM deterministic forecast highs
have been fairly consistent showing highs around 110 degrees in
Phoenix Wednesday through Friday, but these values are closer to
the NBM 25th percentile. Have elected to go closer to the NBM 50th
percentile which boosts highs around 2 degrees across south-
central Arizona, or more in a 111-113 degree range. The marginally
higher surface moisture could keep temperatures from reaching 110
degrees, but with 500mb heights reaching 592-594dm, the
likelihood of overachieving the current NBM deterministic
forecast of 109/110/110 for Phoenix Wed-Fri seems more likely than
underachieving. In fact the latest NBM shows probabilities of
around 50% of reaching 112 degrees in Phoenix on Thursday and
Friday. Can't even rule out breaking the record high of 113
degrees on Friday in Phoenix which the NBM gives a 36% probability
of occurrence. NBM forecast highs across the western deserts for
Wednesday-Friday are mostly in a 112-114 degree range where lower
moisture levels are likely to give more of a boost to temperatures
compared to south-central Arizona. The Excessive Heat Watch
remains in effect for all of the lower deserts for Wednesday-
Friday.

Moisture levels will remain low enough through at least Thursday
that the most we will manage to see is a few isolated showers or
thunderstorms across southern Gila County. This should begin to
change starting Friday as the elongated ridge splits and a new
high center forms somewhere over our region. This may also
eventually open up Arizona to a more favorable southeasterly moist
flow, but models are still uncertain on the timing of the
increased moisture and the depth. For now, it looks like storm
chances are likely to increase Friday into Saturday across the
eastern Arizona high terrain, but chances are likely to remain
quite low (5-10%) across the south central Arizona deserts. Model
ensembles are in somewhat of an agreement showing moisture levels
and storm chances improving from east to west into the Arizona
lower deserts starting Sunday into early next week. There are also
some signs of potential tropical moisture influence during the
first half of next week, but this is still quite uncertain. A
cooling trend also looks very likely starting this weekend and
lasting through the first half of next week due to the lowering
heights aloft and increasing moisture.

.AVIATION...Updated at 1726Z

South-Central Arizona including KPHX, KIWA, KSDL, and KDVT:
No major aviation weather concerns are in the forecast through the
rest of the current TAF package. Light easterly winds continue to
prevail this morning, but westerlies will dominate after 20-21z.
Typical diurnal easterly winds to return late tonight, with a
typical switch to westerly on Wednesday afternoon. Showers and
thunderstorms will stay well east of the terminal area with no
chance of any impacts thru the TAF period. Skies will be mostly
clear with just a few high clouds.

Southeast California/Southwest Arizona including KIPL and KBLH:

No major aviation weather concerns are in the forecast through the
rest of the current TAF package. At KIPL, light and variable winds
will eventually become westerly by this evening/overnight. Speeds
will generally remain AOB 10 kts. At KBLH, light and variable winds
will transition to southerly by late morning with the strongest
speeds occurring during the afternoon and evening hours. Speeds of 8-
12 kts and gusts approaching 20 kts are possible. Lighter southerly
winds to prevail overnight. Patchy haze due to wildfire smoke will
be possible over portions of southeast California, but is most
likely to only create slantwise visibility issues.

&&

.FIRE WEATHER...
Thursday through Monday:
Dry conditions will continue across the majority of districts
through Friday before a gradual increase in shower and
thunderstorm chances over the weekend into early next week. Above
normal temperatures are likely for much of the period with the
hottest days Thursday and Friday. After minimum afternoon humidity
levels mostly in the teens through Friday, improving moisture
should push minimum levels closer to 25% by Sunday. Overnight
recovery will be mostly good in a 35-55% range though some western
districts may only experience recovery closer to 25-35%. Winds
should be relatively light with an afternoon upslope component and
overnight drainage common. Some enhanced afternoon and evening
gusts will be possible at times in western districts.
