.SHORT TERM...(Today and tonight)
Issued at 250 AM CST Fri Feb 17 2017

Warm February weather continues today with record or near record
high temperatures. A dry, warm airmass was in place across the
central plains early this morning under the influence of upper
ridging across the northern and central plains. The upper ridge
axis will translate east through the day as a shortwave trough
tracks across the northern plains, dragging an associated cold
front south through our region. The front is progged to reach our
western zones this morning and our southeast zones toward
evening. Have followed closer to the rap for highs today with
readings ranging from the mid/upper 60s in our northwest zones to
the low/mid 70s in our southeast zones. These readings are a solid
30 degrees above normal for this time of year and will be in
record territory with records standing 71 degrees for KGRI and 74
degrees for KHSI.

Forecast soundings indicate post frontal mixing in our western
counties near h85 with winds at the top of the layer around 20kts
and cannot rule out a couple of hours with wind gusts near 20 mph or
so and combined with low relative humidity values in the low 20th
percentile, will mention near critical fire weather conditions in
the HWO for locations west of a line from Elwood/Lexington to

.LONG TERM...(Saturday through Thursday)
Issued at 250 AM CST Fri Feb 17 2017

Saturday will be only slightly cooler than yesterday and today, but
still very mild for this time of year. Ridging and southerly flow is
expected to increase again on Sunday. Because of this, we will have
to monitor the  potential for fog as low level moisture advects into
the area Sunday morning. Given some uncertainty on coverage/location
I opted to leave it out of the forecast for now, but I wouldn`t be
surprised if we at least have some lower visibilities during that

An upper-level trough will swing into the area Sunday night. Rain
showers will be possible starting Sunday night into Monday. While
there is some instability, thunderstorms continue to look unlikely.
Some uncertainty remains on how quickly rain moves out of the area.
For now, I kept a slight chance of rain for the eastern half of CWA
into Monday afternoon, but if the GFS verifies, the entire area
would be dry by midday at the latest. Tuesday will likely be the
warmest day next week, as high temperatures reach the 70s before a
front pushes through the area Wednesday morning.

Another storm system may impact the area starting next Thursday.
There is a growing consensus that a low will track across western
Kansas into Nebraska Thursday into Friday. Impacts to our area will
be very dependent on the specific track of the system. Of course
there is still considerable uncertainty given the timeframe. Even
though details are likely to change, it currently looks like it will
be primarily rain, possibly changing over to some snow for Friday.
