Severe Thunderstorm Warning 21, NWS El Paso, TX

Area Forecast Discussion
National Weather Service El Paso Tx/Santa Teresa NM
159 PM MDT Sat Jun 1 2019

.SYNOPSIS...
The Borderland sits on the edge of moisture with nightly pushes of
gulf moisture bringing in the moisture, and daily heating working
to dry the region. The result is a mixed bag of rain and storm
chances continuing across the region. Generally dry conditions are
expected west of the Rio Grande, with slight chances for isolated
to scattered chance as you move east from the valley. Temperatures
will run a bit above normal, winds will stay generally low, and
skies will vary, but with plenty of sun. The trend looks to show
some drying across the region through early week, with mid week
and beyond being drier and warmer for the entire region.

&&

.DISCUSSION...
Healthy low-level moisture continues to blow in from the east each
overnight with southeast flow from the east keeping surface
dewpoints in the 50s for areas east of the Continental Divide.
This has been aided by a surface trough aligned north to south
through the heart of our CWFA. Aloft we continue with the
abnormally amplified and deep upper low to our west. For this
evening we are expecting isolated storm development in the region
between the RGV and our eastern CWFA border as daytime heating
destabilizes the environment. Severe storm parameter do suggest
the potential for large hail and strong winds with CAPEs between
1k-3k j/kg, LIs -3 to -6. 0-6km shear of 50kts. Thus a few severe
thunderstorms are likely for areas east and north of El Paso/Las
Cruces this afternoon and evening. Activity should diminish after
sunset with the loss of heating, but a few storms may persist or
redevelop into the nighttime hours.

Sunday looks generally similar to today/tonight. Another east push
will keep low level moisture in the region, with daytime heating
and orographic lift mechanisms generating storm cells in the mid
morning through evening hours. There is some evidence in the
models that the activity will be more limited and focused mostly
east of the Rio Grande. Another day of temperatures a bit above
normal, plenty of sunshine except in vicinity of storms, and winds
generally light except in vicinity of storms.

Monday and Tuesday, in prior model outputs, looked to be
potentially the most convectively active, and wetter days of the
forecast cycle, but this latest suite of models have delivered a
significant shift in the moisture to the east, as they have now
allowed the western upper low to begin to move east. This places
our region under more W/SW flow and shifts the surface trough east
a bit. The result is less E/SE flow to import or keep gulf
moisture in place, with much of it scouring out from west to east.
Dewpoints and PWs look to drop significantly for all but our
eastern zones. We have begun the process of trimming PoPs for our
western and central zones, but haven't cut as deep as models
suggest.

Looking at mid week and beyond the models show the upper low to
have ejected east and out of the region to be replaced by broad
and weak ridging and a less amplified pattern across the western
U.S. For our region this means deep westerly flow with much drier
and somewhat warmer conditions for the rest of the forecast.

.AVIATION...Valid 02/00Z-03/00Z...
A scattered thunderstorm or two will remain possible near KTCS thru
02Z. Otherwise only FEW-SCT100-120 are expected across the area. SKC
overnight will be replaced by FEW-SCT100-120 again after 18Z Sunday.
In general winds will remain AOB 12 KTS thru the period with P6SM
and VFR conditions prevailing.

.FIRE WEATHER...
Isolated to scattered thunderstorms will remain possible across the
Sacramento mountains and portions of Hudspeth county through sunset
this evening. With moisture levels remaining elevated east of the
Rio Grande, eastern fire zones will continue to see a slight chance
for thunderstorms and wetting precip through midweek. Min RH values
east will stay above 20 percent with western zones dropping below 15
percent through roughly midweek. Later in the week drier air will
cover most of the region with single digit Min RH values likely by
the weekend. Afternoon will continue to be a bit breezy, but wind
speeds should stay below Red Flag criteria for most of the week
ahead.
