Flash Flood Warning 8, NWS El Paso, TX

Area Forecast Discussion
National Weather Service El Paso Tx/Santa Teresa NM
247 PM MDT WED AUG 10 2016

.SYNOPSIS...
Abundant moisture will help fuel scattered thunderstorms this
evening and Thursday. A few storms may produce very heavy
rainfall. We will see a continued slight chance for rain on Friday
and Saturday. On Sunday we will see deeper moisture move back into
the area and we will see better rain chances for the start of
next week. Temperatures for the weekend into next week will
continue to run several degrees below normal.

.DISCUSSION...
Moisture, Moisture everywhere but not a drop of rain, well that is
not exactly true a lot of people saw at least some rain, but this
deep tropical moisture plume is not living up to what we had
billed it. As I mentioned in yesterday's discussion, we have
plenty of moisture, marginal instability but where is the lift. We
just doon't have a lifting mechanism to get storms up and going.
A quick view of the water vapor satellite shows plenty of
moisture but no short wave or circulation that could really get
storms going. So today we will have some storms over the terrain
and where the sun can pop out for a bit. Where the storms do pop
up they will produce heavy rain, which could lead to some isolated
flooding of low water crossings and flood prone areas, but we are
not expecting to see wide spread heavy rain. An upper level trough
will begin to push the moisture eastward on Thursday, but we will
still see plenty of moisture to give us scattered afternoon and
evening thunderstorms. By Friday and Saturday we will see "drier"
in place so we will see less thunderstorm coverage, but I sure
can't pull the pops from the forecast. Then on Sunday a weak east
push will swing our winds around to the east and begin to move
some deeper moisture back into the region. The models differ here
with the GFS sweeping the deeper moisture and heavy rains back
into the area on Monday and Tuesday while the ECMWF keeps the
deeper moisture and heavy rains just to our south. For now I've
gone with a compromise between the two solutions.

With all the moisture and clouds and rain chances we will continue
to see temperatures running several degrees below normal. As we
"dry" out for Friday and Saturday we will see high temperatures
creep up a little but they will still be a couple of degrees below
normal. On Sunday, Monday and Tuesday the GFS has highs around 15
degrees below normal. I haven't gone that low, but it does look
like the highs will be running 10 degrees below normal. After one
of the hottest July's on record all these below normal
temperature days are much appreciated.

.AVIATION...Valid 11/00Z-12/00Z
Moist air will remain over the region resulting in SCT-BKN050-070
and BKN-OVC100 but with scattered to numerous areas of MVFR and
isolated areas of IFR ceilings and visibilities in showers and
thunderstorms. Local BKN020 OVC060 1-3SM +TSRA WND VRB25G35KT.

&&

.FIRE WEATHER...
Deep moisture remains over the region with best chances for rain
coming in the next 12 to 24 hours. There will be a slow decrease in
moisture starting Friday...but there will still be more than enough
for at least a daily chance for showers and thunderstorms. Another
surge of moisture is possible early next week when heavy rain could
again be a concern. Temperatures will be increasing the next couple
of days as the drier air filters in and fewer clouds are expected
with a drop back below normal for early next week with the moisture
return.
