PREV DISCUSSION... /issued 304 PM CDT SUN MAR 13 2016/
DISCUSSION...
WV imagery shows the upper trough over central OK, leaving West
Texas and Southeast New Mexico under NW flow aloft and dry/breezy
conditions at the sfc. As the trough moves further east, gradients
will continue to relax, bringing an end to the current RFW early
this evening. Afternoon temps should top out 5-10 deg abv normal.
Monday, West Texas and Southeast New Mexico will settle into a
pattern of NW-zonal flow aloft into the extended, with breezy
westerly flow continuing Monday. Thicknesses peak Monday afternoon,
w/downslope warming pumping temps to their warmest this forecast,
feeling more like early May than mid March. Forecast soundings out
west mix to around 650mb Monday afternoon, where 40+kt westerlies
are forecast, setting up the Guadalupes for another high wind event.
However, H7 pressure gradients don't quite meet 60m/200nm, and NAM
mtns wave signature looks modest at best, so this looks to be a
marginal event. The GFS has weaker wind fields than either the NAM
or ECMWF, and still yields marginal conditions. Thus, we'll upgrade
the watch in the Guadalupes to a warning, but confine it to the
afternoon hours, when mixing is maximized. These winds should also
bleed out somewhat to the adjacent plains, so we'll issue advisories
for there, also. Areal/temporal coverage may have to be expanded my
the mid shift. It goes w/out saying that this will continue to
promote critical fire wx conditions over the western zones, where
extreme fire danger currently resides. Please see fire wx
discussion below for more details.
Tuesday, a very weak Pac front will move into the area, courtesy of
a trough moving thru the Central Plains, followed by a stronger,
secondary front Wednesday. These front will trend temps Tue/Wed
downward, to just abv normal Wed afternoon. Thursday, return flow
brings a warm front thru the SE CWA, setting up a weak
dryline/triple point for a chance of convection ern zones as
disturbances move thru zonal flow aloft. Afternoon temps Thursday
should come in below normal, and stay below normal into the extended
as a stronger, third cold front backdoors the area Friday or so.
This will also keep a chance of convection eastern zones Fri/Fri
night. As a result, Saturday should be the coldest day of this
forecast, w/most locations topping out around 60F or so, with a
modest (yet still blo-normal) rebound Sunday. The upshot of the
pattern Tuesday onward will be less fire wx and better rain chances.
FIRE WEATHER...
A Red Flag Warning remains in effect through this evening for the
Guadalupe Mountains, Van Horn/Highway 54 corridor, the Davis and
Apache Mountains, the Marfa Plateau, Big Bend Area, and Lower Trans
Pecos. Relative humidity values across this area have dropped to
around 10 percent this afternoon, with 20 foot winds of 20 to 30 MPH
across lower elevations and up to 35 to 40 MPH in higher elevations.
Nocturnal recovery will be poor, and with temperatures on Monday
expected to be 10 to 15 degrees above normal, min RH values will
drop to around 5 to 10 percent areawide. Widespread critical fire
weather conditions are expected to develop on Monday, especially
across southeast New Mexico, the Guadalupe Mountains, Van
Horn/Highway 54 corridor, the Davis and Apache Mountains, and
western Permian Basin where 20 foot winds will remain elevated. A
Fire Weather Watch is in effect for the aforementioned area on
Monday afternoon. Not much improvement is expected on Tuesday, with
min RH values under 15 percent areawide. However, 20 foot winds will
be slightly weaker, and may preclude critical fire weather
conditions. But, it will be close.
