.SYNOPSIS...
-- Changed Discussion --
Issued at 104 PM MDT Sun Jun 9 2024

Thunderstorm chances continue again tomorrow with the focus being
over the Sacramento Mtns and eastern portions of the area. Low
end storm chances continue the remainder of the work week for the
area mountains. Otherwise, afternoon breeziness continues with
very hot temperatures in the lowlands this week. Wednesday through
Friday will be very hot with much of the desert lowlands seeing
triple digits. Thursday will be the hottest day of the forecast
with El Paso forecasted to reach around 109F as well as portions
of the Rio Grande Valley in far west TX.

.DISCUSSION...
-- Changed Discussion --
Issued at 104 PM MDT Sun Jun 9 2024

Outflows from the expected thunderstorms east of the Sacs this
afternoon will allow for a decent push of moisture into the area
later tonight. Dewpoints max out at around 55F for far eastern
portions of the CWA with 40F dewpoints possibly pushing as far
west as the Continental Divide. This will help set the stage for
thunderstorms tomorrow, but appears to stay limited to the Sacs
and eastern areas. We can probably expect storms to fire in the
CWA but will begin moving eastward, leaving much of the area dry.
Still expecting gusty outflow winds from thunderstorms and perhaps
even some small hail. However, CAPE is lacking (around a few
hundred J/kg) and wind shear is relatively weak. After Monday, a
cutoff low west of Baja California and another low over the Mid-
Atlantic/northeast CONUS will allow for a ridge of high pressure
to build in bringing very hot temperatures. The dryline will
continue to slosh back and forth over eastern portions of the CWA
each day, which will allow for storm chances in the area
mountains. However, the building high pressure will help suppress
storms for the most part... which isn`t great for storm chances.

The biggest thing we`re watching is the upcoming heat this week.
Monday will be a "cooler" day but temperatures gradually warm up
each day through Thursday with Thursday being the hottest day of
the period. More than likely a heat advisory will be needed
Wednesday with El Paso reaching up near Excessive Heat Warning
criteria (forecasted high temp of 109F nearing 110F) Thursday. A
small dip in temperatures Friday and Saturday, but much of the
lowlands will continue to see upper 90s and low 100s for high
temps these days.

.AVIATION...
(18Z TAFS)
Issued at 1116 AM MDT Sun Jun 9 2024

VFR conditions expected through the TAF period with mid and high
level clouds decreasing after 00Z. Very breezy winds that are
being seen at KELP and KLRU should calm to 15G25KT in the next
couple hours. Breezy winds will continue this afternoon out of
the southwest becoming around 10KT after 02Z. Virga showers should
generally continue this afternoon with thunderstorms possible near
the Sacramento Mtns. A boundary will push in from the northeast
tonight switching wind directions northerly around 06Z-08Z for
KTCS and KDMN. Winds shift easterly in the morning hours tomorrow.

.FIRE WEATHER...
-- Changed Discussion --
Issued at 104 PM MDT Sun Jun 9 2024

Elevated fire conditions continue through the week ahead with min
RHs staying at critical thresholds. The Sacramento Mtns may reach
to around 15-20% each day due to continued low end storm chances.
Dry lightning and gusty outflow winds can be expected near
thunderstorms. Light afternoon breezes continue each day with
Friday having the potential to be the breeziest which will elevate
fire conditions further that afternoon.

Early tomorrow morning and Tuesday morning overnight recoveries
will reach to around 60-90% for Hudspeth and Otero counties with
locations west of the Rio Grande seeing max RHs of around 20-30%.
This is thanks to the dryline sloshing back and forth through the
area each night/early morning. Winds will shift east/southeast on
the moist side of the dryline.

Otherwise, tracking hot temperatures this work week with Wed-Fri
being the hottest, especially Thursday. Ventilation rates will
stay very good to excellent through the work week.
