NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Saint Louis MO 
345 PM CDT Thursday Apr 28 2016 


Short term... (through late tonight) 
issued at 339 PM CDT Thu Apr 28 2016 


Still expect a dry night as upper ridge approaches the area from the 
west and surface low moves over Indiana moves off to the east. 
Clouds currently across northern Missouri and central Illinois will 
slowly move south through the night as the low moves to the east. 
Lows tonight will be slightly cooler than MOS guidance, particularly 
where clouds have kept temperatures down today.

Long term... (friday through next thursday) 
issued at 339 PM CDT Thu Apr 28 2016 


..Friday through Sunday... 


Not too much change to going forecast as showers and thunderstorms 
will begin to overspread the area on Friday. It still appears that 
likely or categorical pops will be needed Friday night into 
Saturday morning as strong moisture convergence will lie 
underneath decent ascent ahead of mid level trough. There is some 
differences between the European model (ecmwf)/NAM vs. The GFS with the European model (ecmwf)/NAM 
showing a slightly more northerly track with the surface low on 
Saturday evening than the GFS. The European model (ecmwf)/GFS could bring more of a 
severe weather threat, so will need to watch this closely. The 
chance of thunderstorms will linger into Sunday before the upper 
low moves out of the area. 


..Monday through Thursday... 


While the details differ, the overall idea of the GFS and European model (ecmwf) 
is the same with the upper pattern becoming more amplified next 
week. Shortwave trough will move southeast out of the Canada early 
next week and phase with upper trough moving east out of the 
southwest Continental U.S.. this will cause northwesterly flow aloft to 
develop by midweek. Rain chances look minimal at this point in the 
northwesterly flow with near normal temperatures as the GFS mean 
ensemble and the European model (ecmwf) 850mb temperatures will be in the 5-10c 
range.

Aviation... (for the 18z tafs through 18z Friday afternoon) 
issued at 1235 PM CDT Thu Apr 28 2016 


A rather large area of stratus covered the upper MS valley and 
northern plains into northern MO and through a good portion of 
northern and central Illinois. The southern extent impacting KUIN was 
located within cyclonic westerly low level flow, and stretched 
just north and west of kcou. KUIN will continue to see MVFR flight 
conditions this afternoon which are expected to improve to VFR by 
00z. Overnight however lower stratus and some light fog will 
likely move back into KUIN and persist into Friday morning. 
Elsewhere predominately VFR flight conditions are expected with 
potential for MVFR stratus on and off at kcou through late 
afternoon. 


Specifics for kstl: 


VFR flight conditions are expected through the forecast taf 
period. Westerly winds this afternoon will become light this 
evening and veer with time.
