Area forecast discussion 
National Weather Service St Louis MO 
353 am CDT Fri Mar 27 2015 


Short term: (through late this afternoon) 
issued at 331 am CDT Fri Mar 27 2015 


A potent northwest flow short wave has been generating an area of 
light rain across western MO since late last night. This is far 
removed from our County Warning Area however there is some very light precipitation 
now showing up in mid MO. Current projections would have this 
across parts of the southern County Warning Area after 12z and at this time I just 
have a mention of sprinkles and flurries. It is moving rather 
quickly due to the digging wave so anything that does occur is 
expected to exit by 14z or so. Otherwise we should see alot of 
clouds this morning and even into the early afternoon as low level 
cold air advection continues, with a trend towards more cumuliform clouds as the 
afternoon progresses. Once again a cold day with below average 
temperatures for late March. 


Glass 


Long term: (tonight through thursday) 
issued at 331 am CDT Fri Mar 27 2015 


Yet another robust short wave trof in the northwest flow will dig 
southeastward thru the mid MS valley late this evening into 
Saturday morning. This wave looks even more potent than the 
present one. The combination of large scale forcing/lift with the 
short wave, strong low-mid level frontogenesis and low level warm air advection 
will result in a band of snowfall. The center of this band looks 
like it should be just west of the cwa, however snow will impact 
portions of central and southeast MO. Since most of it will fall 
at night, this will help the accumulation potential and presently 
have amounts less than an inch. Saturday should be the last day of 
the well below average temperatures. 


Heights aloft begin to rise on Saturday night with the departure 
of the eastern U.S. Trof and surface high pressure retreats 
allowing for low level warm air advection to get underway. Rather strong warm air advection 
persists on Sunday ahead of the next cold front and this should 
bring a rebound in temperatures back closer to normal. The warm air advection 
associated lift along with ascent due to the migrating shortwave 
will bring an area of pre-frontal showers on Sunday into Sunday 
evening ahead of the advancing cold front. 


Temperatures moderate back to above average next week as the 
overall flow aloft decrease in amplitude and gains a more zonal 
component. While there are some timing issues in the deterministic 
models, another shortwave and attendant cold front will bring a 
threat of showers and thunderstorms in the Wed/Wed night time frame.

Aviation: (for the 06z tafs through 06z Friday night) 
issued at 1145 PM CDT Thu Mar 26 2015 


Shortwave is sliding south southeast through western MO as of 04z 
Friday with mid cloud deck moving into taf sites. Further north, 
VFR SC deck on back side of system is sliding south towards 
forecast area. How far south it will make it is hard to pin down. 
For now have it moving into KUIN and kcou over the next several 
hours. As for precipitation with this system, light activity 
remains west of forecast area so kept all tafs dry including kcou. 
Winds to pickup from the north by mid morning with sct to broken 
diurnal SC. By late afternoon/early evening on Friday will see 
winds veer to the northeast ahead of next shortwave that will 
slide through region late Friday night. 


Specifics for kstl: 
shortwave is sliding south southeast through western MO as of 04z 
Friday with mid cloud deck moving into taf sites. Further north, 
VFR SC deck on back side of system is sliding south towards 
forecast area. How far south it will make it is hard to pin down. 
Winds to pickup from the north by 15z Friday with sct to broken diurnal 
SC. By 00z Saturday, will see winds veer to the northeast ahead 
of next shortwave that will slide through region late Friday 
night.
