NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
355 PM CDT Tue Sep 2 2014 


Short term: (through late tonight) 
issued at 355 PM CDT Tue Sep 2 2014 


A weak area of high pressure was centered over northeast Kansas and 
attempting to push some drier air into our region currently. 
Dewpoints have slipped into the lower 60s across northern MO but the 
drier air has been less effective elsewhere where dewpoints remain 
near 70. An expansive area of low stratus clouds existed this 
morning but has since dissipated. 


Clouds are expected to continue to exit or dissipate heading into 
the evening hours and with the weak area of high pressure building 
in and minimal continued dry air advection once the winds become 
near calm, we are expecting fog to develop over the still wet to 
nearly saturated ground for many locations in southwest Illinois and 
extending back up the I-70 corridor into MO. 


It still looks like nocturnal convection will get going with 
development of the low level jet, but will be well west of our area 
and will take much, if not all, of the night to get close to central 
MO. Backed off on pops as a result thru 12z/Wed. 


Favored the cooler MOS temps due to anticipated fog development at 
most locations. 


Tes 


Long term: (wednesday through next tuesday) 
issued at 355 PM CDT Tue Sep 2 2014 


What does develop tonight still looks on track to eventually advance 
eastward into our region on Wednesday but will probably weaken and 
redevelop to some extent with the heating of the day as it slowly 
progresses thru. Backed off on timing a bit with most areas 
probably seeing their best chances for rain on Wednesday afternoon 
versus the morning. 


Lessening chances for rain will then be seen heading into Wednesday 
night, especially into MO, as the leftover convection from the 
daytime limps into Illinois. 


Thursday through Friday still on track to be well above average for 
temps, with Thursday looking increasingly likely it will need a heat 
headline and this may extend into Friday. Friday will depend on how 
fast an approaching cold front, and its associated rain, work into 
the area. 


Best chances for rain rest of the week look to be what develops 
along this late week front: Friday afternoon and night. 


Behind the front, we are still looking at a nice period of below 
average temps for Saturday thru Monday with dry wx. Temps will 
rebound some with rain chances returning on Tuesday.

Aviation: (for the 18z tafs through 18z Wednesday afternoon) 
issued at 1226 PM CDT Tue Sep 2 2014 


Celings across the area have been slow to improve today, and while 
KUIN has gone VFR, MVFR ceilings are still affecting kcou, ksus, 
kstl, and kcps. Expect improvement early this afternoon within an 
hour or two of taf valid time, with ceilings becoming scattered 
VFR and then clearing after sunset this evening. With clear skies 
expected overnight, attention then turns to potential fog 
development. Currently, it looks like Metro taf sites as well as 
kcou have a better chance to see fog, given extra available 
boundary layer moisture due to recent rainfall. Have introduced a 
few hours of MVFR fog for the aforementioned locations for the 
late overnight/early morning time frame, and a brief window of IFR 
for ksus. Otherwise, northwesterly winds today will become light 
and variable overnight, and then become southerly on Wednesday as a 
front lifts northward through the area. Showers/thunderstorms are 
possible area-wide on Wednesday afternoon as well, though 
uncertainties in timing/coverage preclude mention in the current 
taf. 


Specifics for kstl: 


MVFR ceilings are expected to improve to scattered VFR within an 
hour or two of the valid taf period this afternoon, and then clear 
after sunset later this evening. Given clear skies and ample 
boundary layer moisture, have included mention of MVFR fog for 
several hours during the late overnight/early morning time frame. 
While 12z models indicate the potential for some IFR fog 
development, mainly right around daybreak Wednesday, have not 
mentioned in the taf at this time, and will defer to later shifts 
to make the call if model trends are maintained. Northwesterly 
winds this afternoon are expected to become light and variable 
overnight, and then become southerly on Wednesday, and while 
showers and thunderstorms are possible on Wednesday afternoon, 
uncertainties in timing/coverage preclude mention in the current 
taf.
