NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
701 am CDT Wed Oct 22 2014 


Short term: (through late this afternoon) 
issued at 429 am CDT Wed Oct 22 2014 


Broad surface ridge extending from the upper Great Lakes into the 
Ozarks will bring the forecast area another sunny and dry autumn day. 
Intensification of ridge over the past 24 hours has brought a bit 
of cooler air to the region, which should result in afternoon 
temps about 5 degrees cooler than those of yesterday. 


Truett 


Long term: (tonight through tuesday) 
issued at 429 am CDT Wed Oct 22 2014 


There is a chance of rain showers from late tonight through 
tomorrow afternoon as a trough swings through the northern US. 
Instability still looks very limited across central and 
northeastern MO, therefore no thunder is currently forecast. 


Warming trend still looks on track for Friday through Sunday due 
to an upper ridge building overhead. Sunday looks particularly 
warm because surface winds will have turned southerly to 
southwesterly around the back side of an elongated surface high. 
Another low pressure system will approach the region early next 
week, bringing a chance of rain from Monday through Tuesday.

Aviation: (for the 12z tafs through 12z Thursday morning) 
issued at 700 am CDT Wed Oct 22 2014 


VFR weather will continue across the region thanks to sprawling and 
slow moving surface ridge that extends from the upper Great Lakes 
into the Ozarks and lower Mississippi Valley. Much like 
yesterday, the cool dry airmass associated with the ridge should 
mean little if any cloudiness, with east-southeast surface winds 
aob 10kts. 


Specifics for kstl: clear skies and east-southeast winds aob 8 kts 
are forecast for the next 24 hours.
