NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
645 am CDT Fri Oct 24 2014 


Short term: (through late this afternoon) 
issued at 335 am CDT Fri Oct 24 2014 


Weak shortwave will round periphery of mid/upper ridge with main impact 
being an increase in high-level cloudiness for portions of the area. 
At the sfc...a weak frontal boundary will approach northwestern sections 
of the County warning forecast area by 0000 UTC Saturday. At this time...no wet weather is 
expected to accompany this frontal boundary. Temperatures will continue 
on the upswing with highs back above average ranging from the upper 
60s over south-central Illinois to low/mid 70s for portions of central... 
east-central...and southeastern Missouri.

Long term: (tonight through thursday) 
issued at 335 am CDT Fri Oct 24 2014 




(tonight - monday) 


Aforementioned frontal boundary is progged to move through the rest of 
the County Warning Area overnight tonight with little fanfare other than a subtle wind 
shift from the southwest to the west/northwest. With light winds and 
clearing skies behind boundary and associated shortwave trough...did 
lean a bit toward cooler nwp guidance with lows mainly in the 50s across 
the area. 


The Saturday through Monday period will be characterized by well-above 
normal temperatures as upper-level ridging builds overhead and 850-hpa 
thermal ridge advects toward the mid-Mississippi Valley. Have upped highs 
quite a bit from previous forecast into the 70s/80s areawide or some 
10-20 degrees above normal. Lows will also follow suit and get progressively 
warmer. All in all...dry and unseasonably warm will be the rule with 
record or near-record high and/or high low temperatures possible. 




(Monday night - thursday) 


A cold front will move through the area on Monday night with medium-ranged 
guidance in very good agreement with fropa timing and associated rain 
chances. This front should bring a fairly good chance of showers with 
thunder also possible. Instability looks almost non-existent however due 
to low-leevl ridging preventing Gulf moisture from streaming northward. 
However...did leave mention of thunder in the grids as believe there 
should be at least some meager instability...if nothing else due to the 
very anomalous sfc temps. This front will also finally move out the 
unseasonably warm temperatures and usher in daytime highs and nighttime 
lows much closer to seasonal norms for late October. Highs are expected 
to be back in the 60s with lows in the 40s Tuesday through Thursday along 
with dry weather conditions.

Aviation: (for the 12z tafs through 12z Saturday morning) 
issued at 631 am CDT Fri Oct 24 2014 


Fog will be slow to burn off this morning, but shud gradually lift 
to become St before breaking up. Timing is still somewhat 
questionable, but will update as needed. VFR conditions are then 
expected thru much of the evening. An approaching cdfnt will shift 
the winds to the NW, but will remain light. Fog is expected once 
again tonight. Timing and locations are still uncertain, but 
confidence is high enuf to lower vsbys into low MVFR range. 


Specifics for kstl: mainly VFR conditions are expected thru the 
day. However, patches of MVFR cigs may briefly impact the terminal 
this morning. Otherwise, winds are expected to remain light with 
fog possible around sunrise Sat morning. Have not mentioned in taf 
attm due to uncertainty.
