AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ST LOUIS MO
410 AM CST Tue Jan 6 2015
.SHORT TERM: (Through Late This Afternoon)
Issued at 405 AM CST Tue Jan 6 2015
Clipper system exiting region early this morning. Back edge of
sc clouds over southern Iowa will continue to track southeast
today becoming partly sunny by midday. Otherwise, temp trends hard
to pin down. Will see temps continue to fall through 15z or so,
then remain steady or rise a few degrees through the afternoon
hours.

.LONG TERM: (Tonight through Monday)
Issued at 405 AM CST Tue Jan 6 2015
Strong arctic ridge to being moving into region tonight bringing
in much colder air with temps dipping below zero over northeast
Missouri and west central Illinois by daybreak.
Temperatures to continue to fall through the mid morning hours on
Wednesday before steadying out a bit, then as caa really kicks in
temperatures to drop during the afternoon hours. Also, will be
dealing with tightening pressure gradient so winds picking up from
the northwest to north through the period. Gusts to near 30 mph at
times expected on Wednesday. With the colder temps and gusty
northwest to north winds will see wind chill indices approaching
warning/advisory criteria for a large portion of the forecast area
beginning late tonight. So have issued a wind chill warning for far
northern counties from 09z Wednesday through 15z Thursday. Also, a
wind chill advisory will be in effect from 12z Wednesday through 15z
Thursday for areas along and north of I-70.
The wind chill indices will fluctuate through this period, as winds
diminish Wednesday night when ridge moves overhead, but temps will
be at least 20 degrees below normal so kept warnings/advisories
through the period.
As for precipitation chances through this period, still looks like
another quick clipper system to slide through tonight with decent
forcing and enough moisture to produce light snow. Best chances
will be over central/southeast Missouri. With high snow to liquid
ratios this clipper may produce a dusting of snow in a few
locations.
Airmass will begin to modify by Thursday as the center of ridge
pushes off the east. Southwest winds to return with highs in the 20s.
Then another frontal boundary to slide through region Thursday
night, but it will be a dry frontal passage with slightly colder air
moving in for Friday.
Beyond that, extended models show next weather system to move into
region Saturday night, with differences in timing and placement. For
now went with a blend. Slight chance/chance pops Saturday night
through Monday. Temperatures will be in the 20s/30s during the day,
teens/20s at night, so precipitation type mainly in the form of
light snow at this time.

.AVIATION: (For the 06z TAFs through 06z Tuesday Night)
Issued at 1131 PM CST Mon Jan 5 2015
VFR flight conditions are expected to continue to prevail across
the majority of the area for the rest of the night and into
Tuesday. Some ceilings between 2000-3000FT may move into portions
of northeast MO and west central IL before sunrise and persist for
a few hours; but any ceilings further south are expected to stay
at or above 3500FT. Nailing down wind direction will be difficult
for the next few hours as the clipper system moves through. Wind
should generally stay out of the south-southwest...except up in
northeast MO and west central IL where some easterly component has
been observed. Once the clipper moves through the region, expect
winds to increase from the northwest and become gusty Tuesday
morning.
Specifics for KSTL:
Expect VFR flight conditions to prevail at Lambert through the
night into Tuesday. Some ceilings may dip to between 3500-4000FT
before sunrise, but should stay VFR. Wind will be tough to nail
down until the clipper which is now moving through western
Missouri clears the terminal to the east. Wind will then increase
from the northwest and become gusty. Expect gusts to diminish by
late morning or early afternoon.
