NWS Forecaster Discussion




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


Short term: (through late this afternoon) 
issued at 318 am CDT sun may 24 2015 


Will see an gradual increase in rain chances today...particularly 
over the western and northern parts of the County Warning Area as the upper ridge 
moves off to the east which will allow for southwesterly upper flow 
to establish itself over the area. Large area of rain over central 
and western Missouri is being generated in an area of strong low 
level moisture convergence under the broad area of upper level 
ascent. This low level moisture convergence will shift eastward 
today and is being picked up well by the 00z nmm WRF. 


Britt 


Long term: (tonight through saturday) 
issued at 318 am CDT sun may 24 2015 


(tonight through tuesday) 


The NAM has been the most consistent of the models as of late. A 
notable shortwave will move across the area tonight which will bring 
stronger ascent along with strong low moisture convergence ahead of 
it. Will continue with likely or categorical pops over the entire 
area. Then Memorial Day still looks mostly dry as subsidence sets 
in behind aforementioned shortwave trough. Will keep high chance 
and likely pops on Monday night as the next shortwave trough moves 
across the area. Will also keep likely pops on Tuesday as yet 
another shortwave moves across the area. 


Will stick closer to the NAM MOS guidance for temperatures based on 
model preference. 


(Wednesday through next saturday) 


Will continue to go with chances of showers and thunderstorms for 
most of the extended part of the forecast as a series of shortwaves 
moves across the area. A quasi-stationary front will over the area 
which is typical for late may and temperatures will be determined be 
what side the front is on.

Aviation: (for the 12z tafs through 12z Monday morning) 
issued at 629 am CDT sun may 24 2015 


Main question for this taf period will be timing of precip. 
Ongoing precip across wrn MO shud slowly dissipate this morning. 
However, isod to sct thunderstorms and rain shud develop across the region late this 
morning into the afternoon hours. The main threat for precip will 
be late this afternoon thru at least the evening hrs. Precip may 
need to be continued beyond going tafs. Otherwise, winds will 
become sely to sly with gusts to at least 25 kts. Winds will 
become swly late tonight. 


Specifics for kstl: strong and gusty sely to sly winds expected 
today. Main threat for precip remains late this afternoon thru the 
evening hrs. Precip may need to be continued beyond going taf with 
future updates. Winds will become swly late tonight.
