NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
702 am CDT Monday Aug 31 2015 


Short term: (through late this afternoon) 
issued at 326 am CDT Monday Aug 31 2015 


Threat of convection remains the primary question mark for todays 
forecast. Model guidance over the last few days has not offered any 
clear answers to this question...and unfortunately the signals in 
this mornings guidance isn't much more definitive. 


Overnight water vapor imagery indicates middle level shear axis parked 
from the arklatex region into the lower Great Lakes...with the 
animation of the imagery indicating a weak circulation center has 
worked its way NE from western Arkansas to just east of Uno by 08z. 
Meanwhile...subtle drying over S Illinois suggests some very weak 
shortwave migrating SW through stl area on the north side of the shear 
axis. Obviously this is a fairly chaotic upper air pattern, and since 
features are fairly weak models are having a tough time resolving 
sensible weather trends. 


However...almost all guidance...including the hi-res explicit 
output...suggests some threat of convection over southeast sections 
of the County Warning Area today. While current radar data indicates no precipitation 
in/near our area would not be surprised to see some sunrise surprise 
over the next few hours ahead of upper low as it spins its way into 
southern Illinois (which seems to be a trend hinted at by much of the hi- 
res guidance)...with additional spotty storms attempting to flair up 
during the heat of the afternoon in the vicinity of the shear axis. 
For now have primary focus of afternoon development over S Illinois and southeast 
MO in the vicinity of the aforementioned shear axis. 


Slow moving storms could once again pose a threat of spotty heavy 
downpours...similar to the storm that produced 2.57" @ kfam on 
Sunday afternoon/evening. 


Highs today should be similar to those of yesterday. 


Truett 


Long term: (tonight through sunday) 
issued at 326 am CDT Monday Aug 31 2015 


Even though shear axis will shift further southeast, could still see 
some isolated activity this evening, but confidence is low so kept 
mention out for now. Day crew will need to keep an eye out. 
Otherwise, warmer weather is expected through the rest of the 
forecast period with highs in the upper 80s to low 90s and overnight 
lows in the upper 60s to low 70s. 


As we get into the Holiday weekend, upper level ridge begins to 
weaken allowing next weather system to move closer to forecast area. 
Will see an increase in low level moisture and instability by Sunday 
so kept slight chance probability of precipitation in for portions of the forecast area.

Aviation: (for the 12z tafs through 12z Tuesday morning) 
issued at 646 am CDT Monday Aug 31 2015 


Fog should be lifting in those locations that have early morning 
visibility restrictions (kcou, KUIN, ksus) in the 13-14z time frame. 
Otherwise, middle deck has expanded across the region during the 
predawn hours with bases primarily at or above 5kft. This cloudiness 
should give way to a scattered cumulus field developing between 
16-18z...with this cloudiness then dissipating during the early 
evening hours. 


Have omitted mention of convection at this time...and due to the 
spotty nature of the activity will Nowcast this threat and update 
as necessary. 


Specifics for kstl: VFR conditions are expected during the 
period...with clouds at or above 5kft. As mentioned in the primary 
aviation afd will have to keep an eye out for threat of 
convection. Although early morning convection is currently east 
of the metropolitan area we are seeing altocumulus castellanus in the area so some 
development could certainly occur over the next few hours...with 
additional isolated development possible during maximum heating in the 
afternoon.
