Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1146 PM CDT Thu Mar 26 2015 


Short term: (through late tonight) 
issued at 318 PM CDT Thu Mar 26 2015 


Clearing skies spread across eastern Missouri and Illinois this 
afternoon as the storm system from overnight exited off into the 
eastern Continental U.S.. the broad upper level trough that brought shortwave 
system and storms overnight will slowly shift east over the next 
24 hours, but as that occurs we will have a fleeting chance for 
some light precipitation late tonight as cold air sweeps south 
across Missouri. Some light forcing on the western side of the 
cool surface high tonight might result in some light precipitation 
across central Missouri, but otherwise expect overnight lows to 
bottom out in the upper 20s to lower 30s. 


WFO lsx 


Long term: (friday through next thursday) 
issued at 318 PM CDT Thu Mar 26 2015 


With a large upper level trough still shifting east across the 
region Friday, expectations are that the cold weather will persist 
with some of the coldest daytime highs of the week likely. 
However, the broader progressive northwest flow will keep the 
region a bit active into the weekend, and therefore will allow 
for a quick return of above normal temperatures by Sunday. 
However, between now and Sunday we will have another little 
clipper like system slide into Missouri and Illinois early 
Saturday morning. Some light precipitation looks possible across 
central into southeast Missouri, but with expected forecast 
temperatures there are concerns about precipitation type. Have 
continued to use a mix of rain and snow for the precipitation type 
as a result. 


Late in the weekend temperatures will return to more seasonally 
normal levels as the large upper level trough and cool surface 
ridge slide off to our east. Above normal temperatures will 
persist into next work with another chance for thunderstorms 
Wednesday into Thursday next week.

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
