AREA FORECAST DISCUSSION

Issued at 254 AM CDT THU APR 19 2018

Overall quiet and mild forecast ahead, as upper-level ridging
slides across the center of the CONUS, and split flow allows the
upper low currently over southern CA to cut off and slowly weaken
south of the forecast area. Patchy frost this morning will give
way to highs in the upper 50s, due to the competing components of
diurnal heating and cold-air advection resulting from a secondary
frontal passage early this morning. Temperatures will climb into
the 60s Friday, then increased cloud cover and easterly winds
associated with the approaching low may hold Saturday`s highs in
the 50s.

A few light rain showers may sneak into southwestern portions of
the area on Saturday morning as a weak pre-frontal shortwave
trough slips through the region, then another round of light
showers is possible under the upper low Saturday night into Sunday
morning, mainly along the southern border of the CWA. Otherwise,
mainly dry conditions are expected until at least the middle of
next week. Temperatures are expected to warm to seasonal normals
for Monday and Tuesday of next week, then the next system is
expected to push a cold front through the central Plains by
Wednesday morning, which could decrease temperatures at least
temporarily. Showers and perhaps a few thunderstorms are possible
with this system midweek, but will depend on the track and timing
of the front.

The period will start off with VFR ceilings and a NW wind but as a
secondary cold front approaches it will cool the lower levels down
to saturation overnight to develop a MVFR ceiling. This should be
short lived and mostly along the boundary as it passes through.
Winds will shift to the north to north east on the backside of
the front with some drier air helping to clear out the lower cloud
deck.
