NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
342 am CDT Mon may 25 2015 


Short term: (through late this afternoon) 
issued at 338 am CDT Mon may 25 2015 


Area of showers currently over west central Missouri will move 
northeast and will affect some of the northeast Missouri counties 
before 9 am ahead of the mid level shortwave that will move out of 
the area by mid-morning. Otherwise, expect a drier day today as 
area will lie under subsidence in the wake of the shortwave 
trough. Only exception will be over parts of central and southeast 
Missouri into southern Illinois where the atmosphere will become 
unstable which could still lead to a few showers and thunderstorms 
developing during the afternoon hours. High temperatures this 
afternoon will be close to what they were on Sunday, which were in 
the lower-mid 80s. 


Britt 


Long term: (tonight through sunday) 
issued at 338 am CDT Mon may 25 2015 


(tonight through wednesday) 


Will continue to follow the NAM/European model (ecmwf) which has had the best 
continuity as of late. Have kept with current trends on pops 
tonight into Tuesday. A shortwave ridge will move off to the east 
of the area tonight which will allow for a rapid increase in ascent 
after 06z caused by the approach the next mid-level trough and 
increasing low-level moisture convergence. Will keep likely pops 
over much of the southern half of the County Warning Area of the area after midnight 
tonight, and continue them into Tuesday morning as the mid- 
level trough moves through before the showers and thunderstorms 
become scattered during the afternoon. The chance of thunderstorms 
will continue Tuesday night into Wednesday as another weak shortwave 
moves across the area. 


(Thursday through next sunday) 


Rain chances will continue into the extended part of the forecast as 
upper trough over western Continental U.S. Moves into the Great Plains and 
eventually through middle Mississippi Valley by next Sunday. European model (ecmwf) 
shows a series of shortwave troughs with attendant low level 
moisture convergence moving through the area ahead of this main 
trough. This is Worth keeping a chance of showers and thunderstorms 
in each day with the best chance on Saturday when European model (ecmwf) currently 
shows a cold front moving through. Temperatures will stay close to 
normal with 850mb temperatures in the 10-15c range.

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.
