Area forecast discussion 
National Weather Service St Louis MO 
254 PM CDT Friday Jul 3 2015 


Short term: (through late tonight) 
issued at 251 PM CDT Friday Jul 3 2015 


Frontal boundary remains stalled south of forecast area late this 
afternoon. Scattered showers and a few thunderstorms have 
developed over southern Missouri and southern Illinois this 
afternoon. They should diminish by sunset. Otherwise, skies to 
become clear to partly cloudy with lows in the low to middle 60s.

Long term: (saturday through next friday) 
issued at 251 PM CDT Friday Jul 3 2015 


Holiday weekend to be dry for the most part though next system to 
approach region by Sunday, so could see some isolated showers and 
thunderstorms over central MO by Sunday afternoon/evening. 
Otherwise, temperatures in the low to middle 80s on Independence day 
and in the middle to upper 80s by Sunday. 


As next weather system moves in on Monday, will see precipitation 
chances increasing. The best chances of rain will be Monday night 
and Tuesday, but could see rain most days next week as we remain in 
an active weather pattern as this front stalls out over region. Do 
not need anymore rain after record rainfall in June and flooding on 
the rivers still ongoing. Highs will be in the 80s Monday, briefly 
cooling off into the 70s on Tuesday and Wednesday due to cloud cover 
and rainfall, then warm back up into the 80s Thursday and Friday.

Aviation: (for the 18z tafs through 18z Saturday afternoon) 
issued at 1222 PM CDT Friday Jul 3 2015 


VFR flight conditions are expected to dominate through the period. 
Diurnal cumulus has already begun to develop and will dissipate near 
sunset. Diurnal heating will also result in isolated showers and 
perhaps a thunderstorm, mainly from the St. Louis area south and 
east. Odds of any terminal impacts are quite low and if they occur 
should be quite brief.
