Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
547 am CST Thu Nov 27 2014 


Short term: (today through saturday) 
issued at 356 am CST Thu Nov 27 2014 


Clipper system is now well southeast of the cwfa, and only a few 
lingering flurries remain. Expect any lingering precip to end by 
12z this morning and for the rest of the day to be cold and dry. 
Some uncertainty on sky condition today as stratus over Iowa is 
clearing fairly slowly from northwest to southeast. Short range NAM 
and rap 925mb relative humidity field has a decent handle on the clouds at this 
time, so have used a combination of these guidance products and 
satellite observations to try and time gradual clearing today. 
Canadian airmass over eastern Dakotas at this time will drift 
southeast today and will provide the area with unseasonably cold 
air. Cannot argue with MOS high temps in the mid-upper 20s to mid 
30s across the area due to this cold high pressure system's 
influence. 


Models continue to advertise a general pattern shift Friday into the 
weekend with mid-upper level flow becoming more zonal. This will 
allow warmer air to flow back into the area as the storm track 
shifts north. Temperatures will moderate on Friday as the flow 
shifts to the south-southwest on the western side of the Canadian 
high which will have settled in over the eastern Continental U.S.. expect 
temperatures on Friday to be at least 10 to 15 degrees warmer than 
today. Boundary layer moisture will also be on the increase, and 
low level relative humidity progs for Friday night/Saturday morning are showing 
very moist conditions across the area by 12z Saturday from about 
900mb down to the surface. Have therefore increased cloud cover on 
Saturday morning with some gradual clearing during the afternoon. 
Models continue to spit out light quantitative precipitation forecast Saturday, but am still 
skeptical due to the models' tendency to develop precipitation in 
strong moisture return situations even with lifting mechanisms 
aren't present. Indeed, in this case model soundings are showing a 
strong subsidence inversion in the low levels and positive values of 
Omega in the moist layer which would tend to lend credence to a dry 
(tho cloudy/mostly cloudy) forecast for Saturday. Am still sticking 
with above normal temperatures Saturday, though due to expected 
cloud cover have backed off a little bit from warmest MOS guidance.

Long term: (sunday through wednesday) 
issued at 423 am CST Thu Nov 27 2014 


Sunday continues to look pretty mild over the majority of the area, 
with the possible exception of northeast Missouri and west central 
Illinois. Timing differences between the faster GFS and slower 
European model (ecmwf) could mean the difference between a chilly day up north and a 
day with highs between 10 and 15 degrees above normal. Leaned 
toward the warmer solution this morning since the upstream shortwave 
which will drive the front south is well back over Montana in the 
ECMWF, and the GFS solution keeps the teeth of the shortwave up 
north across the upper Midwest. Would like to point out that this 
could easily be wrong. 


Cold front should be through the area by Monday morning according to 
both the European model (ecmwf) and GFS with a 1040mb high building into the 
Midwest. Confidence in the extended forecast beyond Monday is 
pretty low as there seems to be little agreement between the GFS and 
European model (ecmwf). GFS hangs on to quasi-zonal flow aloft through Wednesday 
which is mild and potentially a little wet. European model (ecmwf) develops a 
full-latitude longwave trof over the eastern 1/2 of the Continental U.S. Which 
would be drier and colder. Stuck with the ensemble blend of 
guidance which tended toward a warmer and wetter solution for this 
forecast cycle.

Aviation: (for the 12z tafs through 12z Friday morning) 
issued at 545 am CST Thu Nov 27 2014 


At 1130z, ragged back edge of MVFR cloud deck extends from just 
east of Kalo, to near kcsq, to around kfnb, and is working 
southeast at about 20kts. This rate of movment suggests erosion of 
MVFR cigs at uin and cou around midday and in the stl Metro by 
mid afternoon, which dovetails fairly well with RUC 925mb relative humidity 
trends. There is a large hole in this MVFR deck is over central 
and parts of S IL, but it appears to be working southeast so any impacts 
of this feature will miss our taf sites. Once the low clouds clear 
VFR conditions will prevail for the remainder of the forecast 
period, with any additional clouds aoa 8kft overnight and into 
Friday morning. 


Specifics for kstl: bases of MVFR cigs will slowly increase as we 
head through the morning and early afternoon, with this low cloud 
deck finally scattering out around 22z. Once the lower deck 
erodes, occasional mid level cloudiness (with bases aoa 8kft) can 
expected for the remainder of the forecast period.
