Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
654 am CDT Thu Apr 24 2014 


Short term: (today through Friday 
issued at 329 am CDT Thu Apr 24 2014 


Strong upper level trof is moving east through the Great Plains 
this morning. The surface reflection of this trof extends from 
eastern Nebraska/Kansas southwest into western Texas. Looks like 
good moisture surging ahead of the trof with upper 50s to mid 60s 
dewpoints all the way up into eastern Kansas. All short-range 
guidance has slowed the eastward progression of this system today, 
and thereby also slowing down the precipitation associated with 
it. This should allow for a warmer day than previously forecast. 
Have bumped up temperatures toward warmer mav guidance for today. 
Should see little but spotty showers across most of the area this 
morning, but with increasing chances of precipitation by 18-20z. 
Additional heating of course mean more instability than previously 
forecast as well, and the NAM is forecasting a narrow corridor of 
1200+ j/kg MUCAPE ahead of the front this afternoon along and 
south of the I-70 corridor. With deep layer shear in excess of 40 
kts it does look like some severe storms will be possible. 
Convective Mode is somewhat indeterminate with shear strong enough 
for supercells, but instability probably lacking a bit. I kind of 
like the latest run of the hrrr which as a broken line of storms 
moving across the area this afternoon, tho with a bit more 
instability the convection could easily be more discrete 
initially. Front now looks to be into central Missouri by around 
00z, along the Mississippi River by 03-04z, and through Salem 
Illinois by about 06z. Have adjusted pops for this slower 
progression through tonight. 


Temperatures on Friday are still somewhat in question. A relatively 
mild Pacific airmass will build in behind the front on Friday. 
850mb temps don't really fall off that much and are 10-12c by 00z 
Saturday. This would suggest mid to upper 70s which makes MOS 
numbers a bit too cool across most of the area. Bumped up a bit 
over MOS to compensate.

Long term: (saturday through wednesday) 
issued at 403 am CDT Thu Apr 24 2014 


Guidance continues to come into better agreement for the weekend. 
The secondary front which was forecast to sweep all the way 
through Missouri into Arkansas earlier in the week is now only 
going to get to southern Iowa according to the model collective. 
Still showing a good low level baroclinic zone stretching from 
southwest Missouri up into Iowa Saturday through Sunday with a 
southwest low level jet ramping up to 40-50kts flowing 
perpendicular to the thermal gradient. All models print out some 
light precip in response to this on Saturday, primarily over 
central and western Missouri but I wouldn't be surprised to see it 
a bit further north/northeast as well if this verifies. 
Temperatures will be highly dependent on how much sunshine we end 
up getting, but I leaned heavily on the warmer mav numbers. 


Strong warm advection continues ahead of the ginormous trof which 
will be moving over The Rockies Saturday night, and it looks like 
there could be some nocturnal convection as a a result...mostly 
across northern sections of the County warning forecast area. The trof moves into the Great 
Plains on Sunday and closes off while also becoming negatively 
tilted. The resulting wound up, slow moving storm system will draw 
abundant moisture into the mid-Mississippi Valley from the Gulf 
producing at least a couple of rounds of showers and thunderstorms 
Sunday into Monday night before the associated cold front comes 
through and drier air works into the area. Temperatures should stay 
seasonably mild through the Monday with highs near normal. 


Tuesday and Wednesday the storm system moves slowly overhead and 
then on into the Ohio Valley. Models print out widespread precip 
over the area as cold air aloft moves in with the cut off low. 
Heaviest amounts look to be across northern Missouri and southern 
Iowa associated with the deformation zone. While this makes sense 
conceptually, still not sure I totally believe the medium range 
models as this is a highly anomalous pattern for late April/early. 
Stuck relatively close to guidance though as the mass fields on the 
GFS and European model (ecmwf) are in very good agreement considering strength of 
this system and its anomalous nature.

Aviation: (for the 12z tafs through 12z Friday morning) 
issued at 633 am CDT Thu Apr 24 2014 


Needless to say, a complex forecast for this period for area taf 
sites. Showers/thunderstorms currently ongoing over western 
Missouri will continue to move east-northeast this morning, largely fueled by 
warm advection and a strong southwesterly low level jet. The hrrr 
has maintained a good handle on the evolution of the precipitation 
overnight, thus have taken it into consideration regarding future 
trends today. Thinking is for rain showers/thunderstorms and rain from western Missouri to 
impact kcou by around 15z-16z and KUIN by 16z-17z. This 
precipitation should remain northwest of Metro taf sites, thus 
have not included precipitation mention for Metro sites until late 
this afternoon when rain showers/thunderstorms and rain associated with the cold front are 
expected to impact the area. Expect kcou and KUIN to see a few 
rounds of rain showers/thunderstorms and rain this afternoon, prior to the passage of a cold 
front through the terminals by around 00z (kcou) and 02z (kuin). 
For Metro taf sites, expect rain showers/thunderstorms and rain activity to increase by 
ahead of the front, and continue until the front passes between 
03z-04z, with lingering showers for perhaps another 2 hours 
affecting area taf sites. 


Prior to the onset of precipitation, expect continued 
gusty southerly/southeasterly winds and VFR flight conditions 
along with increasing midlevel clouds. Flight conditions will 
decrease to MVFR during rain showers/tsra, and slowly improve late tonight 
Post- frontal passage. Winds will quickly veer to the west in the wake of 
the front, and remain between 10-15kt overnight. 


Specifics for kstl: 
VFR flight conditions expected to prevail through the first part 
of the forecast period. An area of showers and thunderstorms over 
western Missouri continues to move east-northeast this morning, and is 
expected to remain just northwest of the terminal given latest 
hrrr guidance. Expect rain showers/thunderstorms and rain activity to ramp up late this 
afternoon ahead of an advancing cold front, and persist until the 
front passes through the terminal around 03z-04z. Flight 
conditions will decrease to MVFR in areas of precipitation, with 
ceilings slowly improving overnight after rain showers has ended and 
drier air begins to filter into the region in the wake of the cold 
front. Winds will remain southerly/southeasterly today, gusting to 
20-25kt, and veer quickly to the west behind the front tonight, 
remaining between 12-15kt sustained. Clouds are expected to 
scatter out by daybreak, providing VFR conditions through the end 
of the period on Friday.
