NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
445 am CST Thu Jan 29 2015 


Short term: (through late this afternoon) 
issued at 343 am CST Thu Jan 29 2015 


Observational data at 08z indicated a low pressure area over 
northwest Illinois with a cold front extending to the southwest of it thru 
uin and cou. A warm front extended from near uin southeastward thru 
southern Illinois. Temps have stayed up or risen into the 50s in the warm 
sector of this system, and then have plunged into the 30s quickly 
behind the cold front in Iowa and far northwest MO. Satellite data 
shows low clouds move in shortly after cold frontal passage with 
plenty more where they came from over the upper Midwest and northern 
plains. Radar data shows generally echo-free mosaics over our 
region but some obs at ground level have indicated spotty sprinkles 
or drizzle underneath the low cloud shield that moves in. 
Otherwise, an upper level disturbance was over northern MO early 
this morning with another further upstream over eastern South Dakota--all part 
of the northwest flow aloft that is in place. 


The cold front will push thru the forecast area by 15z with low 
clouds to then inundate and persist for the remainder of the day. 
Some clearing is then expected in central MO late, possibly 
spreading eastward into tonight. High temperatures for the day, 
technically, will all be hit early this morning. But for daytime 
purposes, we should see near steady temps after the initial fall 
shortly after frontal passage. This favors at or below the coolest 
MOS for most locales, except near the front after daybreak for areas 
south and east of stl Metro, where the warmer mav MOS will probably 
work out better given the gradient. 


Pcpn will be a tough call today since there is not much to latch on 
to and radar is having a tough time picking it up. Added some 
scattered sprinkles or flurries for northern MO and central Illinois thru 
this morning where it looks like there will be some better upper 
level support and lift as well as low level convergence. These 
should all be significantly reduced by 18z and have kept the 
afternoon pcpn-free. 


Tes 


Long term: (tonight through wednesday) 
issued at 343 am CST Thu Jan 29 2015 


Surface ridge to build into the region tonight with northwest winds 
gradually diminishing. Colder air to filter in with lows in the low 
to mid 20s. 


On Friday, mostly sunny skies to prevail but temperatures will only 
rise into the low 30s east to low 40s west. 


Surface ridge to move off to the east late Friday night allowing 
southerly winds to return once again ahead of next weather system. 
However, lows will still be in the 20s Friday night. 


As for next weather system, models still have differences with 
placement and timing of frontal boundary. NAM is the slowest and 
warmest initially while the GFS and European model (ecmwf) are a bit faster and 
colder. Will side more with GFS/European model (ecmwf) solutions, with precipitation 
beginning during the day Saturday and spreading east. It will begin 
as a mix of rain and snow, transition to mostly rain briefly during 
the afternoon hours with highs in the low 40s. Then as colder air 
filters in rather quickly, precipitation to change to all snow 
everywhere just after 00z Sunday. As for precipitation amounts, both 
the GFS and European model (ecmwf) 00z Thursday runs are showing highest values along 
the I-70 corridor. However, since there continues to be plenty of 
model differences with this storm, it is difficult to determine 
snowfall amounts and where the maximum axis of snow will occur. For 
now it still does appear that at least a portion of our forecast 
area will see accumulating snow Saturday night and Sunday. 


Beyond that, the precipitation will come to an end Sunday night with 
colder air filtering in and temperatures at or below normal for the 
rest of the forecast period. Extended models do indicate a clipper 
system will slide through Tuesday night and Wednesday with most of 
the energy to the north of the forecast area, so kept slight chance 
pops through the period.

Aviation: (for the 12z tafs through 12z Friday morning) 
issued at 445 am CST Thu Jan 29 2015 


Strong gusty northwest winds and MVFR cigs will be the rule for today for 
all taf sites. While there will be a tendency for cigs to be below 
2000 ft this morning, they should bump up to the 2000-3000 ft 
range this afternoon before lowering again some tonight. There is 
increasing indications that tonight the clouds will hang in for 
much of the night, with some clearing potential from the north 
late. Gusts should also diminish this evening. Some potential for 
sprinkles or flurries for uin early this morning but spotty nature 
of pcpn will probably preclude any mention in the taf. 


Specifics for kstl: gusty northwest winds and MVFR cigs will prevail 
today with diminishing winds and persistent MVFR cigs tonight. 
It now looks like clearing will occur around daybreak Friday from 
the north.
