NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
625 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.

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 12z tafs through 12z Tuesday morning) 
issued at 615 am CDT Mon may 25 2015 


Conditions expected to improve at terminals this morning, 
eventually becoming mostly clear today. Can not rule out isod to 
sct thunderstorms and rain this afternoon into the evening with peak heating. 
However, believe main focus for precip will be late tonight into 
tues morning. MVFR cigs are expected to accompany this precip. 
Otherwise, winds are expected to be swly to sly thru this evening. 


Specifics for kstl: pockets of MVFR cigs shud gradually become 
more sct with dry conditions expected thru this eve. Can not rule 
out isod to sct thunderstorms and rain this afternoon, but any threat shud be 
primarily west of the terminal. Expect precip to move into the area 
late tonight into tues morning with MVFR cigs.
