AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
532 AM CST Tue Mar 3 2015

.SHORT TERM...(Today through Wednesday Night)
Issued at 321 AM CST TUE MAR 3 2015

Today/Tonight: Temperatures across the forecast area remain in the
lower to middle 30s as of this morning. A fine mist to light showers
will continue to overspread the area. The coolest air temperatures
remain over far northeast Missouri, where some light light freezing
drizzle/rain remains possible. Any potential ice accumulation should
be light, on the order of a couple hundredths of an inch, and with
road temps averaging 31-33 degrees in northeast MO, most ice should
be regulated to elevated surfaces, limiting impacts. Primary concern
will end around sunrise as air temperatures warm above freezing.
Otherwise, majority of precipitation will be during the morning
hours before drier air moves into the area this afternoon. Highs
will range from the lower to upper 40s, with a couple locations
perhaps sneaking to 50 degrees. Low clouds will begin to clear late
this afternoon into tonight, leaving mid/high clouds. Lows tonight
will fall into the teens to lower 20s.

Wednesday/Wed Night: Increasing ascent from the phasing of the
approaching upper trough over the Northern Plains and the vorticity
maximum over West Texas, with residual moisture, will lead to
post-frontal precipitation developing Wednesday morning over west
central Missouri and east central Kansas, generally along and south
of the Interstate 70 corridor. Forecast soundings support all snow,
with total snowfall amounts averaging one-half inch or less. Expect
to see a fairly sharp snowfall cutoff on the north side of the
precipitation with drier air advecting into the area upon northerly
winds. With the persistent mid/high cloudiness and cold air
advection, highs will remain unseasonably cold, with readings in the
20s. The cold airmass will be firmly in place by Wednesday night,
and as surface high pressure builds into the region, surface wind
speeds will weaken and skies will become mostly clear, allowing for
decent radiational cooling. Lows will fall into the single digits to
the lower teens.

.LONG TERM...(Thursday through Monday)
Issued at 321 AM CST TUE MAR 3 2015

The extended time looks to be benign with a general warming trend
through the period. Thursday will be the coldest day of the period
as the upper level trough which brought the weather to the area on
Tuesday and Wednesday finally moves through the area on Thursday
morning. This will leave the area under northwest flow aloft while
at the surface Canadian high pressure will move into the forecast
area. Highs will be in the mid 20s to mid 30s which in 15 to 20
degrees below normal for the beginning of March. However, Thursday
night, high pressure will slide to the east and flow at the surface
will increase out of the southwest on Friday. This will occur as
northwest flow aloft also relaxes allowing highs to return to normal
from the mid 40s to near 50. An upper level trough will move across
the Upper Midwest on Saturday which will force a weak cold front
through the area. However, cold air behind this front will be absent
and downsloping flow will allow temperatures to remain in the mid
40s to lower 50s. Saturday night a fast moving area of high pressure
will move through the area and southwest flow will return in its
wake on Sunday. This will help temperatures warm into the upper 40s
to mid 50s. Monday, upper level ridging that has resided across the
western CONUS will begin to build into the area. This will set the
stage for what right now looks to be a very mild week next week.

.AVIATION...(For the 12Z TAFS through 12Z Wednesday Morning)
Issued at 525 AM CST TUE MAR 3 2015

IFR conditions will continue for the next few hours at TAF sites
before mist/drizzle ends and low ceilings slowly improve to MVFR.
Uncertainty exists with ceilings heights by late this morning into the
afternoon, but should see some form of MVFR nearby terminals. Overall
should see ceilings return to high-end MVFR or even VFR this
evening/overnight, but timing is uncertain. Otherwise, wind will
remain gusty today and gradually veer as a cold front
approaches/moves through the area.
