NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
652 PM CDT Thu Jul 31 2014 


Short term: (through late tonight) 
issued at 319 PM CDT Thu Jul 31 2014 


Another cool and quiet night is expected, as lows overnight drop to 
the low to middle 60s across the area, still below normal for this 
time of year. Water vapor imagery indicates a shortwave currently 
over southwestern Minnesota and northwestern Iowa, and a northwest-southeast 
oriented band of precipitation over western Iowa. The shortwave will 
continue to drop southeastward this evening and tonight, and 
could be enough to trigger some showers and perhaps an isolated 
thunderstorm over far northeast Missouri and west central Illinois. 
Feel the window for precipitation in this area is fairly small, as 
the shortwave will remain transient and should be east of the 
Mississippi River and out of our County warning forecast area by around 06-07z. Otherwise, 
diurnal cumulus is expected to dissipate across much of the area not 
long after sunset, with winds remaining light and variable through 
the night.

Long term: (friday through next thursday) 
issued at 319 PM CDT Thu Jul 31 2014 


Slight changes may be in the offing regarding sensible weather 
Friday/Saturday as longwave trough continues to dominate weather not 
only over our region...but also the eastern two-thirds of the country. 
Although shra/ts has been largely non-existent the past several days... 
do believe there is a better chance of seeing isolated activity on 
Friday/Saturday...due to better upper-level support and better instability. 
Otherwise...persistence is the way to go wrt temps...seasonably cool for 
early August. 


Temperatures will moderate back toward normal to start off the new work 
week with seasonably warm conditions expected for the middle of next week. 
Pattern may become more favorable for rain as mid/upper levels become 
quasi-zonal and moisture increases ahead of a slow-moving cold front. 
However...pops only climb into the chance category due to substantial 
differences in timing/track of closed low which develops from the northern 
plains.

Aviation: (for the 00z tafs through 00z Friday evening) 
issued at 650 PM CDT Thu Jul 31 2014 


Showers over Iowa may affect KUIN later this evening, though they 
have shown an overall weakening trend so have not included them 
in the taf site at this time. Some areas of fog are expected to 
develop again tonight... particularly near the rivers like they 
have in recent nights between 09-13z. A weak upper level 
disturbance will move across the area tomorrow afternoon which 
should be enough to generate isolated thunderstorms. The greatest 
coverage will be across west central Illinois, so went added thunderstorms in the vicinity 
at KUIN starting at 17z. The St. Louis Metro taf sites may also 
see this chance, though there is enough uncertainty in timing to 
keep those taf sites dry for now. 


Specifics for kstl: have gone with a dry and VFR taf with light 
winds. There is a slight chance of thunderstorms on Friday 
afternoon, though there is enough uncertainty in timing to leave 
them out of the forecast for now.
