Area Forecast Discussion

.AVIATION...
18z TAF Cycle:

Mostly VFR conditions are expected through the period with
increasing high and mid-level clouds through tonight. Can`t
completely rule out some areas of MVFR/IFR mainly across the
western Panhandles early Monday morning as showers and lower
ceilings push into the area in response to an upper level
disturbance. Isolated thunderstorms will also be possible this
afternoon and overnight, with highest confidence across the
western Panhandles, so included prob30 at KDHT. Amendments may be
needed if an isolated thunderstorm is able to develop this
afternoon near a terminal. Otherwise, south-southwest winds will
be gusty this afternoon, but should subside to around 10 knots
overnight.

PREV DISCUSSION... /Issued 405 AM CDT Sun Aug 20 2017/

DISCUSSION...
An upper low over the southwestern states today will track
northeast across the southern Rockies and approach the Panhandles
by tonight and Monday. Convection early this morning over the
Texas South Plains tracking northeast towards the southern Texas
Panhandle on southwesterly mid and upper flow. Chances for
convection expected to increase today through early this week as
upper low becomes absorbed into longwave trough moving eastward
across the Rockies and Plains states.

Cold front expected to push across the forecast area by Tuesday
afternoon and evening. Brief drying expected around mid week as
upper high builds in over the southwestern states and southern
Rockies and upper flow transitions from southwesterly to
northwesterly during the latter half of the week. Northwesterly
flow becomes active by Thursday night and Friday as a series of
shortwave troughs track east and southeast across the forecast
area. Convection developing over the mountains and higher terrain
of northern New Mexico and southern Colorado will propagate into
the Panhandles during the afternoon and overnight hours late this
week and into the upcoming weekend.
