NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
632 am CDT Tue may 5 2015 


Short term: (through late this afternoon) 
issued at 320 am CDT Tue may 5 2015 


Ongoing activity over far northern portions of forecast area to 
continue diminishing this morning as front shifts a bit further 
north, but with front so close could still see isolated activity. 
Kept slight chance pops going for this area. Otherwise, majority 
of region will be dry today though some isolated activity not out 
of the question for areas along and south of I-70 where there is 
no cap, decent cape and some weak surface moisture convergence. As 
for high temps, low to mid 80s expected. 


Byrd 


Long term: (tonight through monday) 
issued at 320 am CDT Tue may 5 2015 


By tonight, frontal boundary will be well north of forecast area, 
with dry and mild conditions persisting overnight with lows in the 
low 60s. 


On Wednesday another round of activity to fire up on periphery of 
surface ridge affecting Central/Northeast MO as well as west central 
IL, before diminishing after sunset Wednesday night. 


By Thursday, surface ridge shifts further to the east allowing 
weather system to move closer to region. Plenty of low level 
moisture to stream in with surface dewpts in the 60s and several 
shortwaves slide through region as frontal boundary slowly sinks 
south into forecast area. So will see several rounds of showers and 
thunderstorms through the last part of the work week and into next 
weekend. Some differences on timing and placement of system among 
the extended models, so just kept with a blend of the solutions for 
now. Highs will be in the 70s/80s through the period with lows in 
the 60s.

Aviation: (for the 12z tafs through 12z Wednesday morning) 
issued at 626 am CDT Tue may 5 2015 


VFR flight conditions are expected to dominate through the valid 
taf period. A mix of mid and high clouds will be around this 
morning and this should give way to the development of rather 
high-based diurnal cu during the late morning. Isolated showers or 
thunderstorms will be possible this afternoon across southern MO 
and southern Illinois - these should be south of the taf sites and small 
in size and short-lived.
