NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
616 PM CDT Mon Oct 20 2014 


Short term: (through late tonight) 
issued at 317 PM CDT Mon Oct 20 2014 


Frontal boundary has exited the forecast area with surface ridge 
building in. So expect clear skies and light winds tonight. 
Temperatures will drop off into the low to mid 40s with upper 40s to 
low 50s in the St. Louis Metro area. 


Byrd 


Long term: (tuesday through next monday) 
issued at 317 PM CDT Mon Oct 20 2014 


(tuesday through thursday) 


Still looks like Tuesday and Wednesday will be dry as GFS/NAM/ECMWF 
are in good agreement that upper ridge will move into Missouri and 
Illinois from the west. Have added a chance of showers over 
northeast and central Missouri as well as west central Illinois on 
Thursday as another shortwave will be moving quickly eastward into 
the area. 


Continued to use a blend of MOS guidance the next few days which 
fits in well with mixing down 900mb temperatures. 


(Friday through next monday) 


European model (ecmwf) and GFS are in better agreement today that upper ridge will 
begin building into area on Friday and that it will remain over 
the area through next weekend bringing continued dry weather. 
Winds will turn out of the south and 850mb temperatures will climb 
above 10c which support temperature above normal temperature for 
Saturday and Sunday. Both models are showing an upper trough 
moving into the plains with and attendant cold front entering 
Missouri and Illinois by next Monday, so will keep the current chance 
of showers going.
