AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE ST LOUIS MO
719 PM CDT Sun Sep 14 2014

.SHORT TERM:  (Through Late Tonight)
Issued at 322 PM CDT Sun Sep 14 2014

Low level ridge extending from the Ohio Valley into the lower and 
middle MS Valley will drift eastward tonight, but maintain an 
influence on southeast MO and southern IL promoting overnight lows 
in the upper 40s. Meanwhile the main concern will be the threat of 
showers and thunderstorms tonight. Westerly flow aloft will advect a 
region of relatively steep mid level lapse rates presently across 
the Plains across Missouri and into IL tonight. Beneath this, a 
rather broad low level jet will ramp up this evening across the 
central Plains and veer to more westerly overnight.  The 
differential advections will result in elevated instability with the 
LLJ providing good moisture transport/warm advection and lift. 
Current thoughts are elevated showers and thunderstorms will develop 
near the terminus of LLJ with showers and thunderstorms spreading 
across northern MO and into west central IL during the late night 
hours. Given the progressive nature of the flow aloft, I have 
favored the more agressive eastward and southern extent of the NAM 
and local WRF.

.LONG TERM:  (Monday through Next Sunday)
Issued at 322 PM CDT Sun Sep 14 2014

(Monday through Wednesday)

Main concern deals with precipitation chances through Monday night.

The GFS and NAM are in decent agreement with the speed and depth of 
the shortwave trough currently that is dropping south into Montana 
that is expected to deepen and move southeast across Missouri and 
Illinois late on Monday.   Expect the greatest concentration of 
showers and thunderstorms to be across central and northeast 
Missouri and west central Illinois on Monday morning where the GFS 
and NAM is showing the strongest low level moisture convergence 
ahead of the approaching trough.  This morning's 12Z NSSL WRF 
depicts this idea, showing showers and thunderstorms over northern 
Missouri on Monday morning.  Will keep categorical PoPs going during 
morning, and then keep likely PoPs going into the afternoon over 
central parts of the CWA as the cold pushes south through the CWA.  
There will be some lingering showers over southeast Missouri into 
southern Illinois into Monday night as the cold front exits the area.

Tuesday and Tuesday night then will be dry as heights rise behind 
the trough.  I did add some slight chances of thunderstorms across 
central Missouri on Wednesday and Wednesday night as the GFS has 
been consistent in showing some light QPF with a weak shortwave 
moving southeast across the area in northwesterly flow aloft.  

For temperatures, I used a blend of MOS guidance tomorrow, favoring 
the cooler NAM values where I expect there to be precipitation and 
earlier frontal passage in the north earlier in the day.   Used a 
blend of MOS guidance for highs on Tuesday which works well in 
mixing down 900mb temperatures.  Lows are the the agreeable MOS 
guidance.   

(Thursday through next Sunday)

Still looks like the end of the work week should stay dry as surface 
high moves across the area.  The chance of rain will increase next 
weekend as both the ECMWF and GFS show a trough approaching from the 
west on Saturday with the attendant cold front crossing the area 
Saturday night and Sunday.  Temperatures will climb back to near 
normal by late in the week as 850mb temperature climbs into the mid 
teens Celsius.

.AVIATION:  (For the 00z TAFs through 00z Monday Evening)
Issued at 719 PM CDT Sun Sep 14 2014

Mid cloud deck to continue to develop and spread east across
forecast area this eveing ahead of next weather system. Then will
see showers and thunderstorms develop on nose of low level jet and
spread east into KUIN by 08z. As low level jet veers to the east
towards daybreak, activity to slide southeast towards rest of taf
sites. Coverage to become more scattered in nature for sites along
I-70 corridor, so just kept vcnty shower/thunderstorm mention
through the afternoon hours, even after front moves through
region. Could see MVFR cigs behind frontal boundary, especially
taf sites along I-70, so added mention. Begin to dry things out by
late afternoon. As for winds, to persist from the southeast to
south ahead of front, then veer to the west, then to the north by
Monday afternoon.

Specifics for KSTL:
Mid cloud deck to continue to develop and spread east across
forecast area this eveing ahead of next weather system. Then will
see showers and thunderstorms develop on nose of low level jet and
spread east into northeast MO. As low level jet veers to the east
towards daybreak, activity to slide southeast towards metro area.
Coverage to become more scattered in nature, so just kept vcnty
shower/thunderstorm mention through the afternoon hours, even
after front moves through region around 20z Monday. Could see MVFR cigs
behind frontal boundary, so added mention after 01z Tuesday as
metro area dries out. As for winds, to persist from the southeast to
south ahead of front, then veer to the west by 20z Monday, then to the
north by 01z Tuesday.
