NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service St Louis MO 
902 PM CST Thu Nov 20 2014 


Update: 
issued at 856 PM CST Thu Nov 20 2014 


Made some minor tweaks to the forecast for the rest of the 
night, primarily to sky cover to try and better track the clouds 
over the Eastern Ozarks. May have to make some more tweaks to 
temperatures tonight along and south of the I-70 corridor as well 
as hourly temps are falling a bit faster than forecast. Will 
continue to monitor and make any necessary adjustments to the 
forecast for the midnight update.

Short term: (through late tonight) 
issued at 246 PM CST Thu Nov 20 2014 


Quiet conditions are expected tonight as surface high pressure 
drifts southeastward across the region. Northwest flow aloft will 
start to diminish overnight as the upper trough slides off to the 
east; however, light winds and generally clear skies will still 
promote temperatures falling into the teens to lower 20s by early 
Friday morning. 


Laflin 


Long term: (friday through next thursday) 
issued at 246 PM CST Thu Nov 20 2014 


A warm front currently lifting northeast out of central OK will 
push a slug of warm air and increased moisture into the forecast 
area on Friday. Progressively lower stratus will develop from SW 
to NE during the daylight hours, and may be accompanied by patchy 
drizzle during the afternoon and evening. As moisture and lift 
from warm air advection continue to increase overnight, light rain will become 
increasingly likely across the region. Highs Friday may only reach 
the mid 30s to lower 40s due to the arrival of the surface warm front 
late in the day, but overnight lows will be quite similar with 
little to no diurnal temperature fall, and highs will climb into 
the 50s for both Saturday and Sunday in the wake of tomorrow 
evening's warm front. 


Showers and perhaps a few isolated thunderstorms will become 
increasingly likely on Saturday and Saturday night as a shortwave 
trough begins to push into the Southern Plains. Precipitation 
amounts should remain fairly light until Sunday morning, when the 
upper low shifts from central Texas into northern AR, and surface low 
pressure begins to deepen over central and eastern MO. Widespread 
rainfall of an inch to perhaps an inch and a half is possible 
Sunday as the upper low moves from eastern MO into central Illinois and 
the surface low continues to deepen as it lifts northeast. Rain 
should gradually taper off on Sunday night as the southwestern 
system departs; however, a light rain/snow mix or a brief period 
of light snow is possible Monday as a separate system drops down 
from the northwest and drags a surge of cold air into the region. 
No impacts are expected from any wintry precipitation should it 
occur, since most moisture should be swept out of the region by 
the weekend system, and the combination of light quantitative precipitation forecast and warm/wet 
ground should prevent any snow accumulation. 


High temperatures will fall into the 30s to lower 40s for early 
next week as a deep upper trough develops and lingers over the 
central Continental U.S.. things become quite a bit muddier by midweek to 
especially late week when models diverge on the timing/position of 
the exit of the longwave trough, and any systems following in 
behind. For now, have removed pops beyond Monday night due to a 
large amount of uncertainty, and will re-evaluate with future 
forecast issuances.

Aviation: (for the 00z tafs through 00z Friday evening) 
issued at 524 PM CST Thu Nov 20 2014 


VFR flight conditions are expected across the area tonight through 
much of Friday morning. From mid morning through the afternoon, 
deep southerly low-level flow will spread a large area of stratus 
north and northeastward across central and eastern MO into western 
Illinois. Cigs heights will initially be in the low-end VFR category, but 
will lower into the MVFR range during the afternoon at kcou and 
by early evening at the St. Louis area terminals and KUIN. With 
the onset of the lower cigs will also be a threat of light 
rain/showers. 


Specifics for kstl: 


VFR flight conditions will persist tonight through at least mid 
afternoon on Friday. Thereafter an area of stratus will spread 
into the terminal from the south/southwest, initially with cig 
heights in the low-end VFR range. MVFR cigs and light rain/showers 
are expected beginning around 00z/22 Nov.
