Area forecast discussion...updated aviation 
National Weather Service Saint Louis MO 
135 PM CDT sun may 1 2016 


Short term... (through late this afternoon) 
issued at 302 am CDT sun may 1 2016 


Patchy dense fog over northeast Missouri, west central Illinois to 
dissipate and thin out towards daybreak. So main issue for today 
will be the closed upper level low currently over south central 
Nebraska that will finally open up and slide east across northern 
Missouri. Will see scattered showers and a few thunderstorms 
possible, especially along and north of i70 in Missouri and along 
and east of Mississippi River in Illinois. Some of the storms will 
be strong over southwestern Illinois where convective available potential energy will be in excess 
of 1500 j/kg this morning through the afternoon hours, as well as 
decent low level lapse rates and some shear. Could see some small 
hail and wind gusts to 45 mph with the stronger storms. 


As for high temps today, with mostly cloudy skies will have a wide 
variation from the upper 50s far north to the mid 70s far southeast. 


Byrd 


Long term... (tonight through saturday) 
issued at 302 am CDT sun may 1 2016 


Expect thunderstorms to be ongoing at the beginning of the forecast 
period, but to be east of the County Warning Area at 00z this evening. 


Mdls are in fairly good agreement with upper trof hanging up over Iowa 
on Mon with a S/W moving thru the area. While the bulk of the precip 
shud remain S of the area, this S/W and cold temps aloft shud be 
enuf to support rain showers across much of the area. Given the diurnal 
nature of these shra, expect Mon night to be dry with isod to widely 
sct rain showers again on tues as the upper trof sinks thru the region. Some 
uncertainty remains how much of the area will be see any precip, but 
given the expected location of the upper trof tues morning, have 
kept pops confined to the srn two thirds of the County Warning Area. 


The next chance for precip is Wed as another cdfnt drops thru the 
area. Mdls differ regarding how much moisture will be available as 
the fnt moves thru. Will keep low pops going for ern portions of the 
County Warning Area where a S/W rotating around the back of the upper low may 
provide enuf support for some rain showers. The remainder of the forecast is 
dry as a large sfc ridge builds into the area. 


Overall, temp forecast will remain aob seasonal avg. Thru this week 
with a sfc ridge in place as mentioned above. Wed shud be slightly 
warmer with more insolation expected and wly to swly winds ahead of 
the approaching cdfnt. The next warm up shud be Sat as an upper 
ridge builds into the area with sfc winds becoming sly again.

Aviation... (for the 18z tafs through 18z Monday afternoon) 
issued at 106 PM CDT sun may 1 2016 


Specifics for kcou: kcou is far enough west that VFR conditions 
should prevail for the first 0-6 hours of the valid taf pd. 
Thereafter, MVFR cigs are expected for most of the night. Ceilings 
may fall to IFR late tonight, but confidence was too low to 
include in the taf attm. 


Specifics for kuin: IFR conditions are expected for at least the 
next few hours. Minor improvement is possible during the late 
afternoon, but cigs should fall back to IFR this evening. 
Scattered rain showers are possible after 20z. 


Specifics for kstl, ksus, kcps: IFR and MVFR cigs extended farther 
south late this morning than the models had previously predicted, 
and IFR/MVFR cigs are expected to remain in place through the 
afternoon based on upstream satellite imagery and metars. Cigs 
are expected to fall to IFR again tonight, likely after 06z based 
on rap and local WRF soundings in BUFKIT. Light fog is also 
possible overnight. Rain showers are possible after 12z, but the 
St. Louis Metro area should be on the northern fringe of the rain 
shield.
