Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
547 am CST Sat Feb 13 2016 


Short term: (through late this afternoon) 
issued at 358 am CST Sat Feb 13 2016 


Focus will be onset of snow event this afternoon. 


The leading S/W, ahead of the main trof to impact the area tonight, 
is currently just Lee of The Rockies this morning. This S/W will 
move twd the area along with additional moisture to gradually 
saturate lower levels. Mdls still suggests that measurable snowfall 
will reach the area after 00z this evening. However, have increased 
pops for late this afternoon to speed up timing slightly as mdls 
generally do not saturate quickly enuf. Regardless, little 
accumulation is expected this afternoon as the main trof approaches 
and pushes precip ewd. 


As for temps, expect current clouds to spread ewd across the region 
today. Going forecast looked reasonable and only minor changes were 
made.

Long term: (tonight through friday) 
issued at 358 am CST Sat Feb 13 2016 


A longwave trough will continue to prevail over eastern North America 
thru the middle of next week. This will continue the train of 
disturbances, about one every day or two. 


The next disturbance is currently just coming ashore on the Pacific 
northwest. A good model consensus has developed with regards to the 
track of it, thru far northern MO and central Illinois late tonight and 
Sunday morning. This track should become more definitive with the 
12z model runs this morning once full sampling can be attained. The 
beginnings of this event still look to be the same, with an initial 
narrow band of snow that should be ongoing in parts of northeast MO 
early in the evening, with this migrating eastward into west-central 
and parts of southwest Illinois towards midnight. Snow from this will be 
short-lived, but may lead to a quick half-inch or so of accum for 
areas that get it. 


Warm air advection and broadscale lift will increase and become widespread with the 
approach of the disturbance itself after midnight tonight and 
continue into Sunday morning. Pops have been boosted to high-end 
likely and categorical for what should be a light snow event for 
most areas. Already by late Sunday morning over central MO, ice 
crystals are lost in clouds with mid-level drying, and this will 
expand eastward into the rest of the forecast area during Sunday 
afternoon. This will effectively transition the event from 
persistent light snow to a mix of flurries and drizzle, and where 
surface temps are at or below 32f, freezing drizzle. 


The most prolonged snow event should be in the northern cwa, such as 
west-central and central IL, where near 3" of snow is expected, and 
it is there where a winter wx advisory will be issued. Lesser 
amounts expected elsewhere, with most locales set to receive only 
around an inch. 


What was originally progged to be a second part of this event, for 
Sunday night into Monday, is still up in the air. The actual 
disturbance is still well offshore and the models have clearly 
struggled with how the first disturbance will influence and set the 
track of this one, with shifts in the track and timing with each 
model iteration. The GFS is much "wetter" with this than other 
models for Monday, but for now have gone with the main consensus 
which is dry. Something that might not come into better focus for a 
couple more model iterations. Stay tuned, as this could lead to 
additional snow for some areas, although with the progged warmer 
temps, it may limit them to strictly areas to the north of stl 
Metro. Speaking of temps, preferred leaning cool for maxes Monday 
with these disturbances expected to slow down any warming trend. 


Another disturbance is still progged for Tuesday as well, with the 
GFS having come much more in line with the southerly ec/Gem track 
and justifies higher pops. Temps will again try to trend warmer 
with the cold air eroding each day, but it still looks like some 
areas will still be cold enough for pcpn from this event to be snow-- 
mainly north and east of stl Metro, where elsewhere it will tend to 
be rain. A more stubborn retreat of the cold air could mean a few 
inches of snow from this system, so again, stay tuned as these 
disturbances finally track over land and can be sampled better. 


Otherwise, look for a mainly dry forecast from Wednesday on, with 
steadily rising temps with well above normal temps possible for next 
weekend.

Aviation: (for the 12z tafs through 12z Sunday morning) 
issued at 529 am CST Sat Feb 13 2016 


Sfc high will build into the area. Clouds spreading across the 
region will continue to spread ewd across the area. Cigs will 
gradually lower thru the day. A small band of snow has already set 
up across ern Nebraska and will spread sewd, but is currently expected 
to avoid terminals. Eventually, snow will continue to develop and 
become more widespread late tonight into Sun morning. Nly sfc 
winds will gradually veer to become sely tonight as the sfc ridge 
builds ewd. Will need to monitor low level wind shear conditions tonight as a 
strong low level jet builds into the area. Conditions are boarderline attm, 
but will need to be watched.
