Area Forecast Discussion
National Weather Service El Paso Tx/Santa Teresa NM
232 PM MDT Wed Jun 20 2018

.SYNOPSIS...
Very hot and dry conditions will occur over the region as strong
high pressure aloft remains over the southwestern part of the
country. Afternoon temperatures for the next few days will range
from 101 to 107 degrees for most lowland desert locations. The
hottest area will be in the El Paso Metro and nearby areas. Warm
temperatures will persist through the weekend with slightly cooler
conditions next week.

&&

.DISCUSSION...
Strong high pressure over the desert southwest has resulted in a
large of area of subsidence which is resulting well above normal
temperatures across the region. Locally, afternoon highs are
expected to be in the 101 to 107 range in the lowland deserts
with hottest temperatures centered around the El Paso metro area
and the adjoining Rio Grande valley areas. Mountain areas will
experience very warm temperatures as well but still much cooler
than the 100`s across the lowlands. With overnight lows expected
to remain very warm, an extended period of excessive heat is
possible which is potentially unhealthy for people and animals. A
Heat Advisory will be in effect from Thursday morning through
Saturday morning.

There is very little moisture across the region with sunny skies
and clear nights expected the next couple of days. There will be a
weak intrusion of moisture into the eastern areas of Otero and
Hudspeth counties on Thursday that may result in a few isolated
thunderstorms popping up. Best chance of measurable rainfall will
be along the eastern slopes of the Sacramento Mountains on
Thursday afternoon. Even then amounts will generally light and
spotty.

High pressure aloft will weaken somewhat on Saturday and Sunday as
a low pressure system tracks through the northern and central
Rockies. This will cause temperatures to be a few degrees cooler.
However,it will still be hot, with afternoon highs ranging from
100 to 104 degrees for the the lowland deserts. Overnight lows
will also be a few degrees cooler, limiting excessive heat
potential. With the high aloft weakened, a surface westerly flow
ill develop that will lead to low end breezy west winds in the
afternoon during the weekend. Conditions will continue to be dry
as moisture is deflected north and south away from the local area.

Next week will see the high aloft re-establishing itself over the
western part of the country with a weak subsidence flow over a
broad area. In this kind of pattern, modest amounts of moisture
from the south and east may slowly work into the area under the
high. This may lead to a slight increase in thunderstorm chances
later next week, especially over the mountains. Temperatures will
continue to be warm with afternoon highs hovering in the lower
100`s across the lowland deserts.

.AVIATION...Valid 21/00Z-22/00Z
VFR conditions expected for the next 24 hours. Ceilings will be
unlimited today and tonight, with a few clouds building on the east
slopes of the Sacramento Mountains. We will see a bit of a
convergence zone across the area today and tonight. Winds east of
the Rio Grande will be 5 to 10 knots from the east. While west of
the river we will see winds of 5 to 10 knots from the northwest.
Winds on both sides of the river will occasionally be gusty this
afternoon.

&&

.FIRE WEATHER...
Upper level high pressure will continue to control our weather
through the weekend. This pattern will give us high temperatures 5
to 10 degrees above average, skies will be mostly clear and winds
will stay below critical levels. We could see some gusty winds both
this afternoon and again on Thursday, but the winds should not be to
significant. There will also be a slight chance for rain on the east
slopes of the Sacramento Mountains on Thursday. But, again, the main
theme for the next 4 to 5 days will be dry and hot weather. By
Sunday the upper level ridge will begin to retreat back west. This
will lower our afternoon highs a few degrees, but we will continue
to be sunny and dry through the first part of next week. Min RH`s
will generally range from 5 to 10% in the lowlands through the
weekend to 10 to 25% in the mountains. These very low RH`s look to
continue into the first part of next week.
