Area forecast discussion 
National Weather Service Amarillo Texas
523 am CST sun Dec 21 2014

Aviation...
early morning stratus/fog has been slow to spread across the
panhandles this morning but have seen rapid expansion over the past
hour. Kama is at LIFR conditions with visbi fluctuating between 1sm
and 1/4sm. This is likely to continue until sunrise then slowly
improve to VFR around 16z. Kguy has just recently been impacted with
LIFR/IFR conditions and these conditions should also persist through
sunrise before conditions improve. Kdht has escaped lower flight
categories so far but as the fog expands westward we could see a
brief period of MVFR. All terminals should reach VFR by 16z today and
persist through the remainder of this taf cycle. A cold front is
expected to move through the area this evening which will shift the
winds out of the north but remain at or around 15kt. There is a hint
of fog/stratus again tomorrow morning for kama but have left mention
out.

Discussion...
only minor changes have been made to the forecast. Warmer
conditions expected today as low clouds and fog dissipate earlier in
the day.

On Monday...have increased probability of precipitation in the northwest part of forecast
area during the afternoon...due to expected arrival of strong jet
streak.

For Monday night...have continued idea of highest probability of precipitation in southwest
with lowest in northeast...increasing and lowering probability of precipitation accordingly.
Southwest will be favored due to strong jet in region of better
upslope flow in closer proximity to baroclinic zone. Brief shot of
light snow possible Monday night for most sections...with any
accumulations expected to remain below one inch.

Much cooler on Tuesday as north winds and clouds linger. Warmer on
Wednesday and more-so on Thursday before next cold front Thursday
evening. Cooler on Friday and Saturday. No probability of precipitation Tuesday and
beyond.
