Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
402 am CST Sat Feb 6 2016 


Short term: (today and tonight) 
issued at 315 am CST Sat Feb 6 2016 


The elongated and positively tilted upper trof stretching from 
the Great Lakes into the Southern Plains is producing a good deal 
of cloudiness and possibly a few sprinkles near the Lake of The 
Ozarks. This upper trof and the weak surface trof/reflection will 
move to the east of the County Warning Area by midday. Clouds will diminish in its 
wake while surface winds become westerly and low level warm 
advection ensues. Temperatures should see a nice climb over 
yesterday's numbers with highs today around 10 degrees above 
average. The low level warm advection regime will persist tonight 
with clouds again on the increase well in advance of the next 
system.

Long term: (sunday through friday) 
issued at 315 am CST Sat Feb 6 2016 


Winter returns. Big changes ensue this period as a highly 
amplified pattern develops Sunday night into Monday, featuring a 
strong ridge/block along the West Coast and broad deep trof over 
the eastern 2/3rds of the nation. This pattern will unfold as a 
upper low/trof digs southeastward from the northern plains/upper 
MS valley Sunday into Monday. Southwest winds and low level warm 
advection will continue the first part of the day on Sunday 
resulting in another day of above average temps. However the lead 
short wave and height falls will move into the mid MS valley 
during the afternoon sending the first cold front through the area 
by early evening. There could be some spotty light showers in the 
afternoon with the short wave producing weak large forcing and 
ascent from far east central MO into Illinois. The real surge of cold 
air comes in on Sunday night as the upper low/trof continues to 
dig southeast and sends another cold front through the area 
accompanied by increasing and gusty northwest winds and strong 
cold air advection. Vorticity maxima within the cyclonic flow aloft will help 
produce areas/small bands of light snow. Monday will feel like a 
good old winter day with gusty northwest winds and much colder air 
producing blustry conditions. Areas/small bands of light snow/snow 
showers will continue to impact areas on Monday, and some 
locations through the duration could see small accumulations 
ranging from a dusting up to an inch. 


The deep eastern trof will continue to dominate through midweek 
resulting in below average temperatures. The amplitude of the 
upper trof will diminish during the later half of the week with 
broader cyclonic northwest flow aloft. We will have to keep a wary 
eye on fast-moving disturbances within this flow. The models show 
one such clipper system in the Wednesday/Wednesday night time 
frame, however can't agree on location and impacts and this also 
varies with each successive model run. It appears tempertures will 
approach normal levels by week's end, however the European model (ecmwf) has 
another northwest flow disturbance on Friday Worth watching.

Aviation: (for the 12z tafs through 12z Sunday morning) 
issued at 355 am CST Sat Feb 6 2016 


Weak surface high prssure will slide east this morning. The wind 
will turn south-southwest most areas by mid-morning. General 
subsidence behind the upper trof will keep any significant clouds 
from forming or moving into the region. VFR expected for this 
forecast period. 


Specifics for kstl: light southwest wind and VFR conditions will 
prevail as high pressure slides east. High clouds will give way to 
a lower VFR deck late in the period as a cold front moves in and 
the wind shifts to west and picks up in speed.
