AREA FORECAST DISCUSSION
National Weather Service Kansas City/Pleasant Hill MO
626 PM CDT Wed Apr 15 2020

.Discussion...
Issued at 424 PM CDT WED APR 15 2020

Major forecast concern today revolves around a quickly evolving and
potentially quickly escalating system as it ejects into the central
part of the CONUS by Thursday. At the surface a strong ridge is in
place across Minnesota and Iowa, with its southern periphery nosing
southward toward the I-44 corridor. A notable boundary is evident in
both visible satellite imagery and surface observations in
southeastern Kansas and southwestern Missouri. Temperatures on the
cool side of this boundary have struggled to get above 50 despite
ample sunshine, so daytime highs have come up a little short of
forecast temps. This surface ridge will eventually give way to a
fairly deep surface and low level trough by tomorrow and that should
start the process of advecting warm/moist air into the immediate
forecast area.

The forecast for Thursday will be pretty tricky from a temperature
standpoint as well as the obvious concern for moderate to heavy
snow. A surface warm front will likely set up somewhere near
(probably south of) the I-70 corridor, leaving the northern half of
the CWA in the much cooler regime. Temperatures along and south of I-
70 may reach 60 degrees, but areas north of that warm front will
struggle to get out of the 40s. Further north where precipitation
will be more prevalent it's likely that surface temperatures will
hover around freezing through the day on Thursday into Friday. With
little support aloft, the main mechanism for ascent for this system
will be isentropic ascent. This is very evident as deep isentropic
ascent along the 290K to 300K surface. The resultant low level
frontogenesis will provide great and efficient lift for moderate to
at times heavy precipitation along and north of the better low level
convergence. Then comes the question of exactly where these low
level features will set up. Perhaps the most important feature to
watch will be the H85 0C isotherm, as that should give a good proxy
of where to focus on the heavy snow concerns. NAM forecasts have
indicated a slightly stronger H85 cyclone which is pushing the H85
warm front a little further north, into southern Iowa. This would
result in perhaps some lower amounts in the Watch area. HRRR H85
cyclone looks to be a bit weaker and maybe slightly further south,
which may keep the watch area in slight cooler air, and maybe bigger
amounts. Given the high uncertainty, even at this juncture, have
opted for a Winter Storm Watch, but a decision to go with a warning
or advisory will need to be made fairly soon. Further to the south,
away from the better frontogenesis an advisory may be needed, as the
post H85 cyclone cool air comes in and gradually changes
precipitation over to snow, perhaps as far south as the I-70
corridor. This would likely take place Thursday afternoon and
evening, lasting into the early hours of Friday night, with a
dusting to perhaps 2 inches of snow.

Thereafter the pattern looks to be a bit on the quieter side with
temperatures coming back up near or maybe even above seasonal
normals.

While IFR conditions will prevail through the overnight hours,
conditions are expected to deteriorate by late tomorrow morning or
early tomorrow afternoon. Low ceilings with rainfall will move
into east central KS and western MO, with snow increasing across
northern MO. Ceilings are expected to become at least low MVFR and
could possibly become IFR by the afternoon.
