NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
620 am CDT Wed Jul 30 2014 


Short term: (through tonight) 
issued at 259 am CDT Wed Jul 30 2014 


Highs in the upper 70s to lower 80s will be around 5-10 degrees 
below average for this time of year, similar to yesterday. Although 
a few isolated light rain showers or sprinkles cannot be ruled 
out, most areas should remain dry this afternoon. Good radiational 
cooling conditions within a relatively dry air mass (tds in the 
50s) should yield another night with lows in the upper 50s to 
around 60 degrees. 


Kanofsky 


Long term: (tomorrow through tuesday) 
issued at 259 am CDT Wed Jul 30 2014 


In the continued absence of any strong signals for either 
widespread precip or hot/humid conditions, there has been little 
change in thinking since the previous forecast package was issued. 
Ongoing northwest flow pattern will maintain cooler than average 
temperatures through the end of the week and into the first part 
of the weekend. Occasional ill-defined shortwaves moving through 
the longwave trough might produce light rain showers or even a few 
thunderstorms over the next few days, especially during the 
afternoon hours. The upper air pattern begins to change over the 
weekend, and temperatures/humidity are expected to warm back 
towards seasonable levels next week after the departure of the 
longwave trough over the eastern Continental U.S. And the return of southerly 
low-level flow over MO/IL.

Aviation: (for the 12z tafs through 12z Thursday morning) 
issued at 617 am CDT Wed Jul 30 2014 


Other than some locallized radiational fog for the next hour or 
so, VFR flight conditions will prevail through the forecast 
period. Surface high pressure will remain in control resulting in 
light winds, while clouds will consist of diurnal cu and high clouds. 


Specifics for kstl: 


VFR flight conditions will prevail through the forecast period. 
Surface high pressure will remain in control resulting in light 
winds, while clouds will consist of diurnal cu and high clouds.
