NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1248 PM CST Thursday Feb 11 2016 


Short term: (through late tonight) 
issued at 1230 PM CST Thu Feb 11 2016 


A northwest flow shortwave now dropping southeastward into western 
South Dakota will move quickly through our area tonight. Light snow will 
spread southeastward into northeast MO early this evening, then 
through the St Louis Metro area around midnight. Still looking like 
a quick shot of dry, powdery snow with most places picking up to 1 
inch of accumulation, but there may be a narrow band of 1-2 inches 
extending from near irk southeast through the St Louis Metro area. 
Latest NAM and hrrr model runs have the band a little further west 
than previous model runs. Most of the accumulating snow should 
shift southeast of our forecast area by 12z Friday. Low 
temperatures will be similar to the previous night, and around 5 
degrees below normal. 


Gks 


Long term: (tonight through wednesday) 
issued at 225 am CST Thu Feb 11 2016 


..light snow expected this evening... 


Next shortwave will be diving southeast in a similar manner to 
yesterday's and provide the area with another round of light snow. 
It appears that this snow will be a little later in its arrival with 
the main window of accumulation occurring from 6 PM to midnight. 
Once again have about an inch, give or take a few tenths, of snow 
accumulation forecast from northeast Missouri to southwest Illinois. 
This includes the greater St. Louis metropolitan area. 


Snow should taper off after midnight from northwest to southeast, 
with a few flurries possible Friday morning. Thereafter, a very 
cold air mass builds into the region Friday night and Saturday. 
Low temperatures below zero are certainly possible Saturday 
morning across the northern County Warning Area. 


The Arctic high pressure quickly moves east though and by 
Saturday night we could already have a band of warm advection snow 
racing across the County Warning Area. Better chance of accumulating snow appears 
to occur on Sunday, but to be honest, medium range model guidance 
has been flip flopping all over the place with this system the 
past five days and still hasn't landed on a common solution. Best 
to leave pops at a chance for the period in question and give it a 
few more runs before trying to nail down specifics. 


Warm up looks on tap next week as the pattern changes with highs in 
the 50s and maybe even 60s!

Aviation: (for the 18z tafs through 18z Friday afternoon) 
issued at 1237 PM CST Thu Feb 11 2016 


SC has dissipated over taf sites, so will see VFR conditions 
through early this evening as mid and high clouds stream in ahead 
of next clipper system. Timing still similar to last set of tafs 
with snow moving into KUIN/kcou by 02z Friday and stl Metro area 
by 04z Friday. With onset of light snow, will see cigs dip down to 
MVFR with brief IFR visbys as heavier bands of snow move through. 
Snow to taper off between 09z and 10z Friday for taf sites, though 
MVFR cigs to persist. Kcou on western periphery so should see 
MVFR cigs scatter out by 16z Friday. As for winds, to remain from 
the northeast to east as system moves through, then become light 
and variable. By mid morning on Friday, winds to pickup from the 
northwest.
