NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
329 am CDT Friday Sep 4 2015 


Short term: (through late this afternoon) 
issued at 327 am CDT Fri Sep 4 2015 


Expect another very warm and dry day as 850mb temperatures are 
expected stay near +20c favoring highs in the lower-mid 90s like 
the past few days. Went with highs closer to the warmer GFS MOS 
which is closer to mixing down the warmer temperatures. Kept the 
forecast dry as the upper ridge will be building over US. However 
can't totally rule out an isolated thunderstorm this afternoon as 
the atmosphere will become moderately unstable with little cinh. 


Britt 


Long term: (tonight through thursday) 
issued at 327 am CDT Fri Sep 4 2015 


Still expect a dry and very warm weekend as both the GFS and NAM 
continue to show the upper level ridge staying over the region on 
Saturday and Sunday. Will keep with similar highs on Saturday and 
Sunday as thermal fields will be the same in the lower atmosphere 
with southerly winds. 


Showers and thunderstorms will begin to increase over the area by 
Sunday night as a cold front approaches the area from the 
northwest. This front will not actually move through the area 
until Wednesday when a shortwave trough will move across the area. 
As a result...there will be a chance of showers and thunderstorms 
along the the slow moving front from Monday until the front exits 
the area late on Wednesday. Cooler air will move into the area 
beginning on Wednesday.

the weather into the weekend. Dry, VFR with light a southerly 
wind. Sus has the best potential for fog with persistence the best 
forecast. 


Specifics for kstl: continued dry, VFR with a light southerly 
wind.
