Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1234 PM CDT Wed Apr 23 2014 


Short term: (today through friday) 
issued at 342 am CDT Wed Apr 23 2014 


Surface ridge extending from Wisconsin south/southwest into the 
mid-Mississippi Valley and back into East Texas will move east today 
ahead of developing low pressure over the Great Plains. Increasing 
southerly low level flow will result. All short-range model 
guidance develops an area of warm advection showers over the eastern 
plains and pushes it east northeast into northwest Missouri and Iowa 
today. Looks possible that the southeast edge of the showers could 
clip our area, but low level air is pretty dry according to the NAM, 
GFS, and RUC and the primary thrust of moisture return will be back 
over western Missouri so have only introduced slight chance pops 
over our northwest counties. We should see highs pretty close to 
what occurred yesterday even with the warm advection since we'll be 
starting out the day cooler than Tuesday morning. The exception 
will be central Missouri where morning lows should be a bit warmer 
than areas further east. 


The shortwave currently digging across The Rockies will move out 
into the Great Plains tonight and the resulting cold front will move 
into northwest Missouri around 12z. Still looks like showers and 
thunderstorms will be ongoing along and ahead of the front as it 
moves through the County warning forecast area on Thursday. Diurnal heating will likely be 
limited due to cloud cover and advancing precip from the west, so 
instability still looks relatively weak. While there should be 
enough cape for thunderstorms, widespread severe weather does not 
look likely at this time. Stuck closer to the warmer mav guidance 
for highs since morning lows will be around 50 across the area and 
15-20 degrees of rise should be attainable in warm advection this 
time of year regardless of cloud cover. 


Guidance is in good agreement with pushing the front through the 
entire area shortly after 00z. Still have some lingering precip 
east of the Mississippi River Thursday evening as the front exits, 
but dry after midnight. Pacific high builds across the region 
Friday morning. As opposed to a colder Canadian airmass, the 
Pacific Ridge should produce temperatures near or slightly above 
normal in the upper 40s to low 50s Friday morning. West-southwest 
flow develops Friday morning as the high scoots quickly into the 
Tennessee Valley so expect temperatures to rebound into the mid and 
upper 70s.

Long term: (saturday through tuesday) 
issued at 342 am CDT Wed Apr 23 2014 


While the medium range guidance is coming into better agreement on 
the overall synoptic pattern, the smaller scale is still unclear. 
Generally, a secondary cold front will dip south across the upper 
Midwest driven south by the last vestiges of thursday's shortwave. 
The front will stall somewhere across the Midwest on Saturday, 
though models can't make up their minds where. GFS stalls the front 
across south/southwest Missouri Saturday morning, while the European model (ecmwf) 
stalls it out over northern Iowa. The Gem is right about in the 
middle stalling the front over northern Missouri. All three models 
have some low level baroclinicity over our area, whether it is the 
primary baroclinic zone associated with the front (gfs/gem) or a 
secondary baroclinic zone left over from the Pacific airmass which 
will be exiting to the east (ec). Warm advection begins Saturday 
morning with a 30+ kt low level jet pointed at this baroclinic zone 
and all three models print out some light precip. Have therefore 
kept chance pops going in central Missouri, and would not be 
surprised if subsequent shifts need to bump up pops a bit more 
across the area if model trends become more consistent. 


The front remains stalled somewhere between Springfield Missouri and 
Davenport Iowa depending on which model you believe through Monday 
as the longwave trof over the Pacific moves inland, and becomes 
negatively tilted over The Rockies and Great Plains. A strong 
surface low develops as a result and it moves into the Mississippi 
Valley Monday night into Tuesday. The upper trof cuts off and 
becomes stagnant while the surface low tracks across Missouri into 
the Ohio Valley Tuesday. Pattern is more reminiscent of late fall 
or winter than mid to late Spring. Unsure how likely this is to 
happen, but this is at least the second run in a row that i've seen 
do this. Will have to wait and see, but right now it looks like a 
cold/wet end to April.

Aviation: (for the 18z tafs through 18z Thursday afternoon) 
issued at 1223 PM CDT Wed Apr 23 2014 


Area of showers currently over western Missouri is expected to weaken 
this afternoon and is not expected to affect kcou or KUIN at this 
time. Main impact will be increasing midlevel cloudiness at 
terminals. Southeast winds are expected to prevail through the 
night ahead of next system which will move eastward. Southerly 
low-level jet of 40-45 knots near 2000 feet above ground level over central 
Missouri and west- central Illinois could produce low- level wind 
shear and added mention for kcou and KUIN. For tomorrow...another 
area of showers with embedded thunderstorms is expected to move 
into the area from west to east ahead of a cold front from late 
morning into the early afternoon. Actual frontal passage and 
accompanied wind shift is likely to be after this valid forecast 
period. 




Specifics for kstl: 


Increasing midlevel cloudiness is expected through the afternoon at 
the terminal. Southeast winds are expected to prevail through the night 
ahead of next system which will move eastward. Low-level jet axis 
should stay to the west of kstl precluding mention of low level wind shear. For 
tomorrow...another area of showers with embedded thunderstorms is 
expected to affect Lambert Field around midday. However...actual 
frontal passage and accompanied wind shift is likely to be just after 
this valid forecast period.
