Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
554 PM CST Mon Jan 26 2015 


Short term: (tonight through Friday night) 
issued at 349 PM CST Mon Jan 26 2015 


Northwest flow is expected to continue thru Tue across the ern Continental U.S. While 
a ridge extends along The Rockies. Main flow is across the Pacific 
northwest while a cut off low continues to spin off the sthrn California/Baja 
Coast. The closed low gets absorbed into the mean flow on Tue and 
flattens the ridge Tue night/Wed. Upper heights across the mid-MS 
Vly begin rising Tuesday night as a low amplitude ridge builds into 
the area for Wed ahead of the energy, which is the remnants of the 
closed low, approaches the region late Wed night into Thu mrng. All 
this while a separate nthrn stream short wave follows closely behind 
for Thu aftn/Thu evng. These two features will effectively reinforce 
the East Coast trough towards the end of the wk. 


At the sfc, weak low/clipper that produced the light snow across 
Illinois today will quickly exit to the southeast this evng. Not much cold air advection 
behind this system despite nwrly winds. Temps are in the 50s and 
60s in the air behind this system across the plains today. Sfc 
ridge passes to the NE of the forecast area overnight allowing winds to 
become S/south-southeast by Tue mrng. New surface low dvlps in the Lee side trough 
on Tue in response to energy topping the ridge and tracks east-northeast to 
near keok by 6z Thu. This puts the County Warning Area in the warm sector on Wed. 
The 850 mb thermal ridge noses into the forecast area drng the aftn with 
temps ranging 8-12c, though soundings suggest we will not realize 
that potential, only mixing to near 925mb. Guidance indicates that 
most of the precip will remain north of the low track, so have 
just slight chance pops across the nthrn and ern portions of the 
County Warning Area for late Wed night into Thu mrng. The low moves into the ern 
grt lks Thu with the cold air advection on the backside of the storm returning 
temps closer to normal for the end of the wk. Another short wave 
comes onshore along the West Coast Wed night/Thu. This system is 
expected to be a player in a potential wknd storm system. 


There will likely be a significant east/west temp gradient across the County Warning Area 
on Tue due to potential cloud cover along and east of the MS r on 
Tue and a better thermal profile with deeper mixing across cntrl MO 
on Wed. Temp gradient relaxes for Thu and Fri under cold air advection. Used a 
blend of MOS guidance along and east of the MS r on Tue due to 
expected cloud cover. Didn't use the cooler met guidance exclusively 
as it has had a cool bias recently. Went closer to the warmer mav 
across cntrl MO on Tue. Went aoa guidance on Wed due the synoptic 
set up but didn't get carried away due to the limited mixing.

Long term: (saturday through next monday) 
issued at 349 PM CST Mon Jan 26 2015 


The trough that moves onshore late in the wk cuts off over the 
wknd and slowly drifts south along the Baja Peninsula. Meanwhile, 
another short wave drops out of Canada in the mean flow with 
height falls continuing into sun until the trough axis passes sun 
aftn/evng. GFS and European model (ecmwf) both have precip mvng into the area late 
Sat and continuing into sun but differ significantly in the 
details. The GFS has a decent sfc low tracking from the nthrn 
plains into the grt lks while the European model (ecmwf) has a weaker low mvng from 
the sthrn plains into the southeast. Guidance has been anything but 
consistent with this system having it one run and then not on the 
next so do not have a great deal of confidence in any solution 
attm. With colder air in place, the system bears watching.

Aviation: (for the 00z tafs through 00z Tuesday evening) 
issued at 554 PM CST Mon Jan 26 2015 


Next clipper system moving through forecast area this evening, so 
winds to veer to the west then northwest. As for cloud cover, tafs 
along Mississippi River to see MVFR cigs move back in around 02z 
Tuesday in KUIN and around 05z Tuesday in Metro area. Kcou to 
remain mostly clear through forecast period. KUIN to scatter by 
mid morning on Tuesday while Metro are will not clear out til 
towards 00z Wednesday. In the meantime, surface ridge to build in 
and winds will veer to the east towards end of forecast period. 


Specifics for kstl:
