Area forecast discussion...updated 
National Weather Service St Louis MO 
947 PM CST sun Nov 23 2014 


Update: 
issued at 938 PM CST sun Nov 23 2014 


Updated the pops for the overnight. Sped up the timing slightly and 
increased coverage to the south over the next several hrs to account 
for the precip lifting out of SW MO. Limited thunder potential for a 
just a few hrs this evng across the ern Ozarks. Timing on the front 
still looks good with winds increasing significantly after frontal passage. Not 
sold on accumulating snow late tonight into early tomorrow morning due 
to lack of cold enough air being advected into the area to cool the 
bndry layer enough to switch over to all snow...let alone cold enough 
for accums. Think that by the time cold enough air makes it into the 
area the precip will be moving out. Plus...2 inch soil temps are in 
the 40s across NE MO and west cntrl Illinois. Have not pulled the accums but 
wouldn't be surprised if there wasn't any either.

Short term: (through monday) 
issued at 346 PM CST sun Nov 23 2014 


Main concern for tonight will be will there be any snow accumulation 
over northwestern parts of the area as rain changes to snow behind a 
sharp cold front. Most of the County Warning Area has seen rain today and the 
current band which is being forced by strong moisture convergence 
and strong ascent ahead of ejecting shortwave trough will move 
northeast of the County Warning Area this evening. This will cause a lull in the 
precipitation this evening before a second area currently over the 
plains moves into the area later this evening and overnight. This 
area is being frontogenetically forced ahead of a second trough 
currently over the northern plains. Attendant cold front that 
currently extends across central Iowa into far northwest Missouri 
into eastern Kansas will push eastward this evening, reaching St. 
Louis by midnight and east of the County Warning Area by 3 am. Forecast soundings 
suggest that the rain will mix with and then changeover to snow 
after midnight before the frontogenetical band lifts out between 
midnight and 6 am. Current indications are that snowfall amounts 
will be less than 1 inch along and north of a Shelbina to Quincy 
line given the relatively warm soil temperatures (novelty Missouri 
mesonet 2 inch soil temperature is currently 50 degrees) and the 
relative short amount of time that the accumulating snow will 
fall. It will be windy late tonight into tomorrow as decent 
gradient winds set up behind the cold front. However it does not 
appear that we will hit advisory criteria at this time. 


Do not expect much clearing tomorrow as forecast soundings show some 
minimal cape in the lowest levels tomorrow afternoon suggesting some 
isolated snow or rain showers will develop in the low level cyclonic 
flow. Highs tomorrow are only a few degrees warmer than lows tonight.

Long term: (monday night through next sunday) 
issued at 346 PM CST sun Nov 23 2014 


(monday night through wednesday) 


Next notable trough that will move through the area will be on 
Wednesday which the European model (ecmwf) and GFS both show light quantitative precipitation forecast across the 
County Warning Area. Have increased pops a bit across the area, with the highest 
amounts over the northern County Warning Area where current track of the surface 
low will be. Temperatures will stay below normal during the period. 


(Thursday through next sunday) 


Overall confidence in forecast during this period is not high as the 
both operational GFS and European model (ecmwf) and their ensembles have had continuity 
issues the past few days with the timing and strength of the troughs 
that will move across the area later this week. Latest runs are showing 
quasi-zonal flow during the period with shortwave troughs moving quickly 
across the area. While the GFS is developing some quantitative precipitation forecast over the region 
on Saturday, this is different than yesterday's run, so will discount 
for now. Will go dry during this period given the inherent difficulties 
in timing precipitation in zonal flow.

Aviation: (for the 00z tafs through 00z Monday evening) 
issued at 531 PM CST sun Nov 23 2014 


Specifics for kcou, kuin: several issues to discuss for the 00z 
taf cycle. Continual new development of rain/dz across central and 
northern MO makes it less likely to see a substantial break in the 
precip at kcou and KUIN compared to farther south and east. 
Conditions should remain IFR for the near future. The next area of 
precipitation to affect kcou and KUIN was associated with an 
approaching cold front. The rain is expected to mix with and 
change over to snow with minor accumulations possible (one-quarter 
to one-half of an inch or less) between 08-13z. A significant wind 
shift will accompany the front. Winds will become west to 
northwest and increase to around 20 kts sustained with gusts of 
30-35 kts. It is possible that instability snow showers may 
develop tomorrow afternoon due to the very cold air aloft, but 
confidence is too low to include in the tafs at this time. This 
possibility will be re-examined for the 06z issuance. 


Specifics for kstl, ksus, kcps: several issues to discuss for the 00z 
taf cycle. It looks like the ongoing rain/dz will diminish over the 
next few hours (vsbys should increase at least briefly), but cigs 
will probably remain IFR due to the substantial low level moisture 
in place. The next area of rain to affect the Metro area taf sites 
is associated with an approaching cold front. It is possible that 
some of the rain may mix with snow as precipitation is ending, but 
confidence is too low to introduce rasn at Metro area taf sites 
yet. A significant change in winds will accompany the front 
between 10-14z. Winds will become west to northwest and increase 
to around 15-25 kts sustained with gusts of 30-35 kts. Finally, it 
is possible that instability snow showers may develop tomorrow 
afternoon due to the very cold air aloft, but confidence is too 
low to include in the taf attm.
