Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1139 PM CDT Sat Apr 25 2015 


Short term: (through late tonight) 
issued at 324 PM CDT Sat Apr 25 2015 


The severe weather threat has failed to materialize thus far due 
to what appears to be a lack of robust buoyancy owing to marginal 
boundary layer moisture and heating. There is a narrow window and 
zone with some limited potential for the next few hours, roughly 
immediately south of St. Louis and east of Farmington through 
extreme southwest Illinois where the lead surface low and 
convergence zone is located. This zone will also close quickly as 
the lead low migrates E/se and winds shift to the north and west 
behind the low. Showers and some isolated thunder will linger into 
the early evening from St. Louis south/east but as alluded to the 
severe threat should be over by 23z. High pressure and cooler air 
will settle into the region for the remainder of the night with 
north-northeast winds. Any precipitation beyond the ongoing should 
be isolated-patchy in nature. It appears some clearing of the 
stratus will commence across northeast Missouri and west central 
Illinois after 09z as northeast winds advect drier air into the area. 


Glass 


Long term: (sunday through next saturday) 
issued at 343 PM CDT Sat Apr 25 2015 


High pressure will continue to build into the area on Sunday with 
north-northeast low level flow. This flow will lead to continued 
southwestward clearing of the stratus while cirrus gradually thins 
from north to south as well. Present indications are that there 
will be a decent amount of afternoon sunshine and this should 
allow temperatures to rise into the 60s, resulting in highs a tad 
below average for late April. 


Deepening of the northeast U.S. Vortex and accompanying 
positively tilted upper trof will keep a northerly component to 
the flow aloft through Tuesday. This will also maintain 
surface high pressure as it builds southward through the MS 
valley. An upper low and trof which evolves in the southwest U.S. 
Over the next 24 hours will then migrate into the Southern Plains 
on Tuesday and into the lower MS valley Tuesday afternoon-night. 
The southern track of this upper system along with dry lower 
tropospheric east-northeast flow should keep precipitation at Bay 
to the south of the region, with predominately high clouds Monday 
through early Wednesday. 


A tranquil and dry pattern will dominate mid week into early next 
weekend. The flow aloft will be rather amplified initially with 
the trof axis to our east and surface high pressure maintained 
into the later part of the week. By the weekend it appears we 
should see ridging aloft move into the nation's midsection and a 
return to southerly low level flow, bringing above normal temps 
well into the 70s and pushing 80 in some locations.

Aviation: (for the 06z tafs through 06z Sunday night) 
issued at 1114 PM CDT Sat Apr 25 2015 


Band of IFR cigs will continue to drop south overnight. Assoc -dz 
should also come to an end over the next few hours. Dry NE flow is 
expected to push the IFR cigs south of the terminals early this 
mrng leaving a low end VFR ceiling deck in place for most of the day. 
Model relative humidity indicates the VFR cigs should clear out drng the late 
mrng but based on the existing amount of upstream cloud 
cover...think that might be too optimistic...plus there should be a 
diurnal component to the clouds as well. Skies should clear out by 
Sunday night. 


Specifics for kstl: 


-dz should be coming to an end around 6z. IFR cigs are expected to 
remain thru the night and slowly raise Sunday mrng becoming VFR by 
mid morning as the cloud deck drfts south. Clouds should clear by 
tomorrow evng.
