NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
325 PM CDT Fri Mar 27 2015 


Short term: (through late tonight) 
issued at 325 PM CDT Fri Mar 27 2015 


The stratocumulus cloud deck will gradually dissipate and advect 
southeast of our forecast area late this afternoon and into the 
early evening hours due to increasing subsidence as the surface 
ridge extending from northwestern WI southwest into central OK 
shifts southeastward into our forecast area, and as an upper level 
trough along with cold mid level temperatures shift east of our 
area. Any flurries or sprinkles should end by late afternoon. Mid 
level cloudiness will spread into our area later this evening and 
overnight as low-mid level warm air advection increases over the 
western portion of the forecast area on the nose of a westerly low 
level jet ahead of an approaching northwest flow shortwave. A band 
of snow is forecast to drop southeastward into central MO late 
tonight due to low-mid level frontogenesis. The GFS is stronger and 
further east with the area of frontogenesis and hence has more quantitative precipitation forecast 
and has its placement further east compared to the NAM. The European model (ecmwf) 
model is a compromise between the NAM and GFS. For now will go with 
a compromise between the European model (ecmwf) and the GFS model, the NAM appears a 
little too far west with its narrow NW-se band of quantitative precipitation forecast. Looking at 
the thickness forecasts, model forecast soundings and surface 
temperatures the precipitation type should be snow. For now will go 
with about one half inch of snow accumulation late tonight for the 
cou and jef area. 


Gks 


Long term: (saturday through next friday) 
issued at 325 PM CDT Fri Mar 27 2015 


(saturday through monday) 


Mdls continue to show a strong northwest/southeast oriented band of frontogenesis 
along the wrn County Warning Area border. The NAM seems to be a wrn outlier and have 
trended twd the GFS/ECMWF/local 4km WRF. Still appears heavier snow 
will remain west of the County Warning Area. 


The sfc ridge will slide just to the east of the area bringing sely 
winds to the region for Sat night. This shud help keep temps up 
slightly and have trended twd the warmer guidance. 


Sun will bring a brief warm up with a cdfnt pushing thru the region. 
Have increased pops with good low level forcing with a fairly strong 
S/W and good ulj support. Main question will be how far S precip 
will develop with weaker support, but have kept at least low pops 
across the srn portions of the County Warning Area. 


Despite the cdfnt mentioned above, thermal ridge builds over the 
area with swly to wly flow shud help push temps into the 60s for 
Mon. 


(Tuesday through friday) 


Mdl solns begin to diverge quickly with the European model (ecmwf)/Gem solns bringing 
a weak cdfnt thru the area while the GFS keeps the fnt north and pushes 
the thermal ridge across the region. While both mdls have pushed 
this fnt further S compared to yesterday, have cooled temps only 
slightly for now compared to the prev forecast. 


The European model (ecmwf) and Gem have height rises across the region with the GFS a 
split flow bringing rain to the County Warning Area. Have kept low chance pops due to 
the uncertainty and to keep some persistence with the prev forecast. 
Mdls are in better agreement with a cdfnt pushing into the area on 
thurs, but the more zonal European model (ecmwf) stalls this fnt further north while the 
GFS is more progressive. Have raised pops where mdl guidance agrees, 
but kept some lower pops going into Fri due to uncertainty.

Aviation: (for the 18z tafs through 18z Saturday afternoon) 
issued at 1150 am CDT Fri Mar 27 2015 


Diurnally enhanced cumulus field will continue early this 
afternoon, but should eventually dissipate later this afternoon as 
subsidence increases as the surface ridge over the northern 
plains builds southeastward into MO. There may be 
flurries/sprinkles or even light snow/rain showers early this 
afternoon in the St Louis Metro area. An upper level disturbance 
will drop southeastward into the area tonight. Mid level clouds 
are expected ahead of it with at least a brief period of light 
snow, MVFR cigs and MVFR/IFR vsbys at cou late tonight/early 
Saturday morning in a narrow snow band which will impact central 
MO. Precipitation should remain west of uin, stl, sus and cps. 
North-nely surface wind will veer around to an E-sely direction late 
tonight as the surface ridge shifts southeastward into the Great 
Lakes region. 


Specifics for kstl: sprinkles or flurries early this afternoon 
from a stratocumulus deck. These clouds will dissipate late this 
afternoon with mid level clouds advecting southeastward into stl 
late tonight. The mid level clouds will advect southeast of stl 
Saturday afternoon. Nly surface wind will become light this 
evening and veer around to an Ely direction by late tonight, then 
to an E-sely direction Saturday morning.
