NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service St Louis MO 
135 am CDT Wed Sep 17 2014 


Update: 
issued at 129 am CDT Wed Sep 17 2014 


Based on latest vsby trends of surface obs as well as hrrr and 
lamp guidance will be going out with a dense fog advisory for our 
eastern counties shortly...until 10am. It's possible we may need 
to expand a bit west and north in a few hours, and will at least 
mention patchy fog as far west as eastern MO. However, upstream 
clouds heading our direction should limit threat of widespread 
dense fog, especially west of the Mississippi River.

Short term: (through tonight) 
issued at 230 PM CDT Tue Sep 16 2014 


A weak S/W will approach the County Warning Area late tonight bringing a chance 
for storms to wrn and srn portions of the County Warning Area late tonight. 
Otherwise, expect clouds to continue to break up during the 
afternoon and into the evening. Clouds are expected to build into 
the region from the west tonight ahead of the S/W. Have trended twd 
a compromise of guidance for wrn portions of the County Warning Area and twd the 
cooler guidance for ern portions. Latest guidance suggests fog will 
develop late tonight impacting srn and ern portions of the County Warning Area 
where radiational cooling will be greatest. 


Long term: (wednesday through next tuesday) 
issued at 309 PM CDT Tue Sep 16 2014 


(wednesday through friday) 


Main concern continues to be rain chances tomorrow into tomorrow 
night over mainly central and southeast Missouri. GFS/NAM/ECMWF are 
still in relatively good agreement in dropping a weak shortwave 
trough across Missouri during the day tomorrow. Each of these 
models shows some weak low level moisture lingering across central 
and southeast Missouri into Wednesday night, so will continue a 
chance of showers and thunderstorms in this area. This scenario is 
depicted pretty well at least through 00z by the reflectivity on the 
NSSL WRF. Thereafter will maintain a dry forecast Thursday and 
Friday as a surface ridge moves across the area at the same time a 
upper ridge builds in from the west. 


Went on the cooler side of guidance for highs the next couple of 
days given the easterly surface flow and it matches up better with 
mixing down the 900mb temperatures. Likewise followed the cooler 
NAM MOS for lows. 


(Saturday through next tuesday) 


While there is still some disagreement between the GFS/European model (ecmwf) 
regarding the speed and depth of a trough that will pass through the 
area this weekend, it still appears that the attendant cold front 
will move through on Saturday night and early Sunday. Will keep 
chances of showers and thunderstorms going Saturday into Sunday. 
Will keep Monday and Tuesday dry at this point as we will be on the 
back side of the the upper trough, though the latest runs of the GFS 
is showing a secondary through dropping down in the northwesterly 
flow on Tuesday. This is a new trend that the European model (ecmwf) is not 
showing. Still expect at or just above normal temperatures ahead of 
the front on Saturday before they drop back below normal for early 
next week given expected 850mb temperatures in the 6-9c 
range.

Aviation: (for the 06z tafs through 06z Wednesday night) 
issued at 1104 PM CDT Tue Sep 16 2014 


Northwest flow aloft will keep the mid fall like conditions in 
place. Upper air wave will move through overnight to reinforce the 
northwest flow. Models trying to generate precitation at the nose 
of a low level (5000 ft) jet of 30 knots over the MO/Kansas border. So 
far no sign of anything develping. Cou looks to be the only 
location with a shot at rain, but will keep them dry for now. Band 
of 4k to 5k clouds rapidly advancing southeast. That may put a stop to 
any MVFR ceilings. Lower clouds over southern MO are slowly 
expanding a bit to the north. Some fog at sus and cps will will 
bring temporary MVFR conditions until the clouds arrive. Wednesday 
looks to be VFR. 


Specifics for kstl: 4k to 5k deck should arrive from 08 to 09z. 
Will go with that and hold off on any MVFR ceilings. Lower clouds 
over south central MO may work their way north and the mav 
guiidance brings them in for a short time. Not that confident they 
will arrive, so will leave out for now.
