Area forecast discussion...updated 
National Weather Service St Louis MO 
910 PM CDT Thursday Jul 30 2015 


Update: 
issued at 909 PM CDT Thursday Jul 30 2015 


A dry and tranquil night remains on tap with surface high pressure 
in control and a few passing high clouds. Min temperatures will be a tad 
below average in the 60s.

Short term: (through late tonight) 
issued at 354 PM CDT Thursday Jul 30 2015 


Quiet weather will continue across the area tonight as high pressure 
builds south through the Missouri River valley. Clear sky and light 
wind should allow for good radiational cooling again tonight, and we 
should cool off nicely. Used this morning's lows and dewpoint 
temperatures as a guide blended with a dose of MOS guidance to yield 
lows from around 60 to near 70 in the stl metropolitan tonight. 


Carney 


Long term: (friday through next thursday) 
issued at 354 PM CDT Thursday Jul 30 2015 


The upper level pattern amplifies over the Continental U.S. Through the 
weekend and into early next week as the Hudson Bay low deepens and a 
Sharp Ridge builds over The Rockies. This will result in northwest 
flow aloft over the Mississippi Valley. Low level flow turns back 
to the south-southwest over the Great Plains on Friday and into 
northwest Missouri Friday night. This low level southerly flow will 
spread eastward over the weekend and combined with a couple of fast- 
moving shortwaves will produce scattered thunderstorms...the first 
potentially Friday night into early Saturday morning and the second 
late Saturday night into early Sunday morning. Temperatures should 
be seasonably warm...and dewpoint temperatures will likely climb 
back into the low 70s which will make it feel more like the dog days 
of Summer. GFS and European model (ecmwf) differ slightly out in the medium range 
with the GFS continuing to amplify the pattern and pushing a cold 
front through Missouri down into Arkansas and Oklahoma by Wednesday 
evening while the European model (ecmwf) is not nearly as strong. Regardless there 
should be an increased chance for precipiation by middle week and 
potentially lower temperatures.

Aviation: (for the 00z tafs through 00z Friday evening) 
issued at 629 PM CDT Thursday Jul 30 2015 


VFR conditions are expected through at least Friday afternoon. 
Weak cold front will come through the region late Friday afternoon 
and evening. However...weak surface convergence and upper level 
forcing for ascent suggest isolated showers and storms...at best 
so do not have any mention in tafs. Partly cloudy to mostly clear 
skies should prevail with light west/northwest winds. 




Specifics for kstl: 


VFR conditions are expected through Friday evening at kstl. Weak 
cold front will come through the region Friday evening. 
Any storms that do fire late Friday afternoon to the north look 
to weaken quickly with loss of instability Friday evening so 
terminal expected to remain dry. Partly cloudy to mostly clear 
skies should prevail with light west/northwest winds.
