Area Forecast Discussion

1245 PM CDT Thu Mar 15 2018

The 18Z aviation discussion follows....


Low pressure over southeast Colorado will move into Kansas by this
time tomorrow. Wind speeds will remain relatively high this
afternoon, with a modest drop around sunset, including a slight
backing in direction. From west to east across the region tomorrow
morning, starting around 12Z in the west, to about 16Z along
I-35, winds will increase again in speed--and shift to more
westerly. No other aviation weather concerns are currently

12Z TAFs.

South winds will increase this morning and continue to be gusty
through the day and overnight. Only mid-high level clouds are
expected through most of the period. There will be some potential
for MVFR stratus towards 12Z Friday with increasing moisture
moving in from Texas, although have not added any to the TAFs
quite yet as it may be very late or after 12Z.

We know we sound like a broken record, but fire weather concerns
continue to be the main issue in the forecast over the next few
days. Dewpoints will be increasing across much of the area today,
but may be a little late to arrive as dewpoints are still just in
the mid 30s to lower 40s across central Texas this morning. Still,
the moisture return will keep minimum afternoon humidities above
20 percent across much of the area... except in the northwestern
and western edge of the forecast area. With humidity expected to
fall to near or below 20 percent, will upgrade the fire weather
watch to a Red Flag Warning, and add Woods, Alfalfa and Major
Counties where moisture will be late to arrive.

Tomorrow, dry air will move into the area behind a dryline and
Pacific front, and much of the area will see minimum humidity
below 20 percent. Winds will also be increasing as a storm system
moves over the Plains and this will lead to critical fire weather
conditions across portions of the area, especially northwest. We
will also continue to watch the track of the surface low as it
moves east through the Central Plains. If it moves across at a
latitude much lower than currently forecast, the stronger winds
will be possible which will bring more widespread critical fire
weather conditions. Given the expected low RH, breezy conditions,
and location of the low level thermal trough, will go ahead and
issue a fire weather watch for much of the area.

Elevated to near-critical conditions will continue for the next
few days with warm temperatures and areas of low humidity. Sunday
and Monday look to be the breeziest days.

As far as precipitation chances, there are low chances of showers
tonight in the east as the models show some slight QPF signal
associated with an initial shortwave ahead of the main system. But
chances are not high. There is a somewhat higher chances on
Saturday night and Sunday with moisture return and a shortwave
ahead of the next trough.
