Area Forecast Discussion...UPDATED
National Weather Service Amarillo TX
1241 PM CDT TUE JUL 26 2016

For the 18Z TAFS, isold tstms may develop later this afternoon and
evening just about anywhere in the OK and TX Panhandles. Since
coverage is expected to be isold and corresponding confidence is low
that any one TAF site will be impacted by tstms, have omitted this
weather element from this fcst issuance. Will monitor radar trends
this afternoon in the event amendments become necessary.

12Z Issuance...VFR conditions expected to persist through the period
for all sites. Slight chance at thunderstorms today, but confidence
on timing has gone down so removed timing from this set of tafs.
Think handling with amendments for the brief periods of storms, if
they affect the sites, would be better. Winds will be northwesterly
for KAMA and KDHT through the morning, then swing clockwise to more
southeasterly. KGUY is already southeasterly and should remain so
through the period. Light winds are expected unless thunderstorms
should form.


PREV DISCUSSION... /Issued 412 AM CDT TUE JUL 26 2016/

An upper high over the Four Corners and Great Basin Region will
maintain a more northerly or even northeasterly upper flow across the
Panhandles through the latter half of the week. By Friday...the upper
flow transitions back to northwesterly. The upper high builds back to
the east towards the Panhandles this weekend with the upper high
settling in over the central and southern Rockies by late Saturday
and Sunday. Convection chances today through Thursday will be fairly
isolated and the western and southern sections of the forecast area
may have better chances. A frontal boundary is forecast to push south
into the Oklahoma Panhandle or possibly the extreme northern or
northeastern Texas Panhandle and then become stationary by the end
of the week. The front should then lift back to the north and east as
a warm front over the weekend. Chances for convection should increase
by the end of the week and into the early part of the weekend as the
upper flow becomes northwesterly. Drier conditions expected by late
in the weekend as the upper high builds in from the west.
