AREA FORECAST DISCUSSION

Issued at 306 AM CDT SUN APR 15 2018

Unseasonably cold temperatures and very light wintry precipitation
will be the focus in the short term, before warmer conditions
redevelop early in the work week. For this morning, lobes of
vorticity rotating around the upper low will continue to bring
periods of light wintry precipitation to the CWA. The depth of
saturation has decreased overnight, resulting in a mix of flurries
and patchy freezing drizzle, and minimal to no accumulation. This
broad area of very light precip will transition eastward through
the day as the upper low shifts eastward but may pulse east/west a
bit as the vorticity maxima drop southward around the low center.
Persistent cloud cover and cold air advection should hold high
temperatures in the mid to upper 30s, which may set a new record
minimum high temperature in KC (previously 41) and STJ (previously
43).

Clouds will begin to clear in time for temperatures to fall into
the 20s CWA-wide tonight, resulting in another potential hard
freeze for areas that have experienced recent growth. Afterward,
winter will loosen its grip on the center of the country and
temperatures will begin to climb, recovering into the 50s Monday
and to near 70 Tuesday. A weak cold frontal passage will dampen
temperatures a few degrees below normal in the upper 50s for the
end of the work week, then another shot of wet weather is possible
for the weekend.

Issued at 1224 PM CDT SUN APR 15 2018

An upper level low pressure system is slowly moving east producing
some light flurries, especially across central and north-central
MO, but this shouldn`t impact visibility. MVFR ceilings are also
being observed thanks to this system. Ceilings should lift to
low-end VFR this evening around sunset. Right now the low-end VFR
ceilings should stick around through 06Z, but it is possible
they hang out for most of the night before clearing out. Winds
will remain out of the northwest for this forecast period. They
will also remain gusty. They will weaken some after sunset, but
the pressure gradient will still be tight enough across the
forecast area for gusty conditions.
