National Weather Service Amarillo Texas
500 am CST Sat Nov 28 2015

MVFR conditions at dht and Guy are expected to go down hill this
afternoon. LIFR conditions at Ama may improve to IFR...but then
conditions are expected to get down into the LIFR range again
overnight. Light northerly winds will become light and variable
before switching around to the east and southeast...but they will
remain under 10 knots. Foggy conditions overnight at Ama may cause
visibilities to get down to one half mile or less. Have not gone that
low just yet as confidence is not high right now.

Latest water vapor imagery shows a deep closed low in the west with
a plume of middle-high level moisture streaming northeast across our
region. Weak difficult to define shortwaves have aided in the
development of periods of precipitation through the afternoon and
evening and this continues early this morning mainly over the
southeast third of the forecast area. Calls around to the areas where
precipitation is ongoing reveals a wide range of ptypes including
sleet...snow and freezing rain. Based on trends will likely be able
to cancel at least portions of the Winter Storm Watch and Ice Storm
Warning. We will make a final call after monitoring trends for
another hour or two.

Light sleet/snow/freezing rain will continue into the early/middle
morning hours across the southeast third with a gradual decrease in
probabilities throughout the day. Models linger low level moisture
through much of the day which will result in overcast conditions and
possibly some freezing drizzle. A shortwave trough will approach on
Sunday and models show weak isentropic lift redeveloping over the
area. Temperatures should warm above freezing keeping most of the
precipitation rain after perhaps some freezing drizzle at the onset.
Later in the night temperatures will cool to at or below freezing
and the precipitation may end as freezing rain...especially across
the north. Amounts will be light. After the precipitation associated
with this system exits Sunday night dry weather is expected next
week. High temperatures will gradually increase from the 40s to the
middle and upper 50s late in the week.
