 Winter Weather Advisory  Statement as of 4:12 PM CST on February 27, 2015


... Winter Weather Advisory in effect from noon Saturday to noon
CST Sunday...

The National Weather Service in St Louis has issued a Winter
Weather Advisory for snow and ice... which is in effect
from noon Saturday to noon CST Sunday.

* Timing... snow is expected to move into portions of southeastern
Missouri late Saturday afternoon. Snow is expected to continue
through the evening hours before changing over to a mix of sleet
and freezing rain after midnight Saturday night. Freezing rain
is expected on Sunday morning with a changeover to plain rain by
midday Sunday as surface temperatures rise above the freezing mark.

* Accumulations... up to 2 inches of snow and a light glazing of ice.

* Winds... southeast 5 mph or less.

* Impacts... the wintry precipitation will result in hazardous
travel conditions... especially on bridges... overpasses... and
untreated roads. Parking lots and sidewalks will become
slippery as well.

Precautionary/preparedness actions...

A Winter Weather Advisory is issued for a variety of winter
weather conditions... such as snow... blowing snow... sleet... or
freezing drizzle and rain. It only takes a small amount of wintry
precipitation to make roads... bridges... sidewalks... and parking
lots icy and dangerous. It is often difficult to tell when ice
begins to form... so do not be caught off guard.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
410 PM CST Fri Feb 27 2015 


Short term: (through late tonight) 
issued at 354 PM CST Fri Feb 27 2015 


Not too many issues for the forecast overnight. Increasing high 
and mid level clouds with a light wind transitioning to easterly 
Saturday morning. Despite the clouds, have lowered low temps just 
a bit along our eastern border mainly due to deeper snow depth. A 
solid 4 - 6 inches on the ground there should keep low temps on 
the low side, which matches the mav guidance pretty good. 


Jpk 


Long term: (saturday through next friday) 
issued at 354 PM CST Fri Feb 27 2015 


Primary focus remains on the Sat/sun system and another one early 
next week. A four-segment Winter Weather Advisory will be issued 
for the Sat/sun system to handle progressive onset of pcpn (west 
to east), p-type variation (snow in the north vs. Mix in the 
south), and very flexible headline criteria for collaboration. 


Sat/Sun: widespread pcpn expected especially Sat night into sun. 
Favorable factors include strong isentropic ascent between 
290-305k, strong frontogenesis in h9-800 mb & 800 mb-700 mb layers, mconv 850 mb 
low level jet on sun, and precipitable water values of 0.6-0.8". Initial thoughts are around 
3-5" of snow across the northern County Warning Area and about 1-3" across the 
southern County Warning Area plus a light glaze of freezing rain and sprinkling of ice pellets at 
times across the southern half when warmer air spreads northward 
on Sun morning. Transition to liquid across the south with 
continued low level warming then back to wintry mix with cooling. 
Further refinements likely. Many repeated adjustments were needed 
to many individual grids for near seamlessness at the expense of 
other fcst details. 


Quasizonal flow aloft becomes swly aloft on sun/Mon after a piece 
of the large cutoff low over California/Baja California ejects ewd in response to 
an upstream kicker trof. Most areas probably see a break in pcpn 
on Sun night/Mon between systems. 


Mon/Tue: pcpn expected with the lifting wmfnt on Mon night and 
also with the sfc low on Tue/early Tue night. Favorable factors 
include backbuilding 500 mb jet and rer dynamics on Tue, strong 
mid/upper vort Max, precipitable water values in excess of 1" (aoa +2sd for mar), 
and strong mconv with 850 mb low level jet. Marked warmup on Tue-- highs reach 
mid to upper 50s on the warm side of the warm front. Conditions 
are favorable for scattered thunderstorms at times. Colder temps 
return behind the cdfnt and remain across the region through the 
middle/end of the week.

Aviation: (for the 18z tafs through 18z Saturday afternoon) 
issued at 1050 am CST Fri Feb 27 2015 


VFR forecast for the most part. MVFR ceilings may make their way 
into the area depending on the speed of the next system. Looks 
like a pretty good warm air advection snow for Saturday night 
into Sunday. 


Specifics for kstl: VFR through 18z Saturday, then will bring in 
some MVFR ceilings late in the period as the weekend system moves 
closer. Timing right now is a question, so will mainly introduce 
as an "alert"feature.
