NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service St Louis MO 
134 am CST Tuesday Feb 9 2016 


Update: 
issued at 132 am CST Tue Feb 9 2016 


Updated forecast through sunrise to account for widespread light 
snow across eastern Missouri and Illinois. Up to an inch of fluffy 
snow can be expected given latest radar trends and a peak outside. 


Cvking 


Issued at 936 PM CST Mon Feb 8 2016 


Very light snow and flurries currently continue to affect much of 
the County Warning Area late this evening. Next weak upper-level disturbance will 
swing through the area late tonight and bring another round of 
more widespread light snow along and east of the Mississippi 
River. Additional accumulations of up to a half inch of new snow 
are possible.

Short term: (through late tonight) 
issued at 345 PM CST Mon Feb 8 2016 


Large trof remains centered over the Great Lakes region thru the Ohio 
Valley. This trof continues to send S/W swd over the area. As each 
vort Max drops thru the area, areas under these shud see a brief 
shsn that reduces visbys to around a mile or so. Have kept likely 
pops for the ern half of the County Warning Area to account for this. Still do not 
anticipate accumulations with the showers due to them being very 
brief. 


As for temps, with continuing cold air advection across the region, have trended 
twd the coolest guidance thru tonight. 


Tilly 


Long term: (tuesday through next monday) 
issued at 345 PM CST Mon Feb 8 2016 


Deep cyclonic flow and additional, yet sheared, disturbances will 
result in a slow, measured retreat of the stratocumulus cloud field 
to the east thru Tuesday, and until the deck breaks, the lingering 
threat for at least flurries will persist. 


Model guidance has come into somewhat better focus on a clipper 
system late Wednesday into early Thursday--enough to finally include 
a mention of snow in the forecast for most areas, especially east of 
the MS river. This is a system that they had been advertising with 
some consistency, yet quite varied on strength and track, to not 
really include a mention of until now. If some of the stronger 
solutions verify, a stripe of 2-4" of snow may be realized out of 
this, while the weaker faster versions would result in a dusting of 
snow instead. Something to watch over the next day or two. 


Otherwise, a prolonged period of below average temps is forecast 
from now thru the upcoming weekend, with temps possibly moderating 
towards average during early next week. The slower retreat of our 
current cold airmass being pushed back to late this week and the 
still anticipated arrival of a reinforcing Arctic blast on Friday 
will result in little to no moderating period between the two. The 
first shot of cold looks like it will culminate late Tuesday night 
into Wednesday morning, where wind chills may bottom out approaching 
-15f (wind chill advisory criteria) for some areas in northern MO and 
central Illinois. 


A well advertised reinforcing Arctic blast continues to look set for 
Friday, preceded by another clipper system which could drop 
additional snow accums. This cold blast looks to peak on Saturday 
and Saturday night, with a slow recovery thereafter. The recovery 
may not be as great as the MOS guidance suggests, however, with the 
western Continental U.S. Ridge persisting and allowing for slower movement on 
these cold highs as well as keeping the door open for additional 
reinforcing shots. 


It is this uncertainty with temps late in the forecast that will 
continue to plague how to handle what could be a better organized 
system for early next week to affect our region. Maintained pops 
for sun-Mon timeframe, but large model splits continue to be seen 
with the GFS weaker and more progressive (and less quantitative precipitation forecast and cold) 
than the stronger, more digging system depicted by the ec. This 
system continues to show good potential on having a widespread 
wintry impact if it can also hold on to the cold and will be watched 
closely over the next several days.

Aviation: (for the 06z tafs through 06z Tuesday night) 
issued at 1131 PM CST Mon Feb 8 2016 


Another round of flurries and light snow will affect KUIN and the 
Metro terminals through early Tuesday morning. Some of the snow 
will likely briefly reduce visibilities to IFR so have a tempo 
group. Further west...appears kcou will only see just flurries. 
Still expect any remaining flurries/light snow to end by noon 
across the area with ceilings slowly lifting and scattering by 
late Tuesday evening from west to east. 




Specifics for kstl: 


Another round of flurries and light snow expected through this 
morning. Have a tempo group for IFR visbys in heavier snow shower 
activity. By afternoon...expect ceilings to climb back to VFR and 
scatter out Tuesday evening.
