NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1129 PM CDT sun may 24 2015 


Short term: (through late tonight) 
issued at 200 PM CDT sun may 24 2015 


Isolated to scattered thunderstorms will continue to develop in 
the unstable airmass this afternoon ahead of the main band of rain 
and storms that is aligned north to south from near irk to 
sgf. Initial tornado threat will be with the mesoscale convective vortex structure that is 
currently moving north-northeast from Sedalia to Kirksville the 
next few hours. Perhaps this activity will skirt our western cwa, 
but the larger threat of strong to severe thunderstorms will 
arrive a bit later this afternoon and evening. A strong shortwave 
will lift northeast across the region with an arcing band of 
thunderstorms accompanying it. The enviroment will be supportive 
of embedded mesovortices and short lived tornadoes as low level 
shear and helicity values will increase as the surface wind begins 
to back to the south-southeast as low pressure forms to our west. 
This activity should be progressive and therefore the threat of 
flash flooding remains low in our County Warning Area. 


Cvking 


Long term: (memorial day through sunday) 
issued at 200 PM CDT sun may 24 2015 


Memorial Day still looks dry as subsidence is expected behind 
tonights system. Temperatures should be quite mild with some 
sunshine expected. The dry weather will not last long thought as 
next shortwave will move through the area Monday night and Tuesday 
morning bringing the area another round of showers and 
thunderstorms. Timing of convection has ME doubting we see much 
severe weather on Tuesday. 


The pattern remains active the remainder of the week and straight 
into next weekend. Chance of thunderstorms each day with mild 
temperatures. Severe weather chances will depend on timing of 
individual shortwaves and available instability/shear. 


&& 


Aviation: (for the 06z tafs through 06z Monday night) 
issued at 1123 PM CDT sun may 24 2015 
other than some sprinkles or an isolated shower it appears that 
the threat of rain is rather low for the St. Louis regional 
terminals the remainder of the night. Showers will continue to 
impact kcou and KUIN with potential for IFR conditions. Otherwise 
MVFR flight conditions/cigs are expected to develop across the 
area and impact all terminals overnight with conditions improving 
and clouds becoming scattered by mid morning on Monday. 


Specifics for kstl: 
other than some sprinkles or an isolated shower it appears that 
the threat of rain is rather low for the remainder of the night. 
MVFR flight conditions/cigs are expected to develop across the 
area and impact kstl overnight with conditions improving and 
clouds becoming scattered by mid morning on Monday.
