NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
621 am CDT Tue Mar 31 2015 


Short term: (through tonight) 
issued at 330 am CDT Tue Mar 31 2015 


Northwest flow and dry conditions in place today and tonight. An impulse 
embedded in the northwest flow will drag a weak cold front thru the forecast area 
today but with limited moisture to work with...should be a dry 
frontal passage. The front settles well south of the area by Wed mrng. There 
is an outside chance that this feature may spark off some very isld 
convection across sthrn Illinois/MO late this aftn/evng. Chances look 
minimal with slightly better chances just south of the County Warning Area.

Long term: (wednesday through monday) 
issued at 330 am CDT Tue Mar 31 2015 


Upper lvl ridge slides across the region on Wed with a significant 
short wave following closely behind along the US/Canadian border 
with a weakness in The Heights extending SW to a short wave coming 
on shore along the West Coast Wed night. The lead short wave will 
induce a low to dvlp across the nthrn High Plains and move east 
along the international border Tue night lifting into sthrn Canada 
Wed. This feature will drive a cold front into the cntrl Continental U.S. For 
the end of the work week. Weak sfc ridge slides east of the County Warning Area by 
Wed putting the region in sthrly flow between the retreating high and 
the approaching bndry. Winds are expected to become rather gusty by 
Wed aftn. Strong wwa and decent bndry layer moisture may be 
sufficient to produce a few isld rain showers/tsms Wed aftn...primarily 
across MO where the better moisture and instability should reside. 
The better chances of precip on Wed appear to be across SW MO where 
the tail end of the weak cold front from Tue attempts to lift back 
north. Wed should be the warmest day of the week with the strong 
sthrly flow. 


The cold front approaches the area Wed night with most guidance in 
agreement...timing wise...bringing the bndry into the NE County Warning Area around 
12z Thu. The front makes steady progress south thru the day and 
should exit the sthrn forecast area around 00z Fri. The bndry slows Thu night 
due to an area of low pressure that is fcst to form along the tail 
end of the bndry across the sthrn High Plains in response to the 
trailing short wave. The low is fcst to track from Arkansas to the Ohio 
Vly on Fri ending the precip threat by aftn. It still appears that 
the nthrn cwa's best chance for precip will be with frontal passage Thu mrng 
with the remainder of the precip Thu night and Fri being along and 
south of i70. Thunder is expected to accompany the front on Thu but 
should be confined closer to the front across the sthrn forecast area Thu 
night and Fri. 


Temps on Thu will depend on frontal timing/position and assoc 
precip. The slower either are then the warmer temps will be. Fri 
will be a cool day with plenty of clouds and precip. Friday will 
be a cloudy cool damp day with highs mainly in the 50s. 


A low amplitude upper lvl ridge will attempt to build into the 
region over the wknd with a sfc ridge moves from the cntrl plains to 
the Tennessee Vly. It should be a decent wknd with mostly clear skies and 
seasonal temps. Upper flow is fcst to transition to a broad SW 
flow...so chance pops have been introduced for the beginning of 
the week.

Aviation: (for the 12z tafs through 12z Wednesday morning) 
issued at 616 am CDT Tue Mar 31 2015 


VFR flight conditions expected through the forecast period with few 
if any clouds. Cold front currently passing through the St. Louis 
area will settle southward with high pressure building in and 
light winds tonight. The only issue is some marginal and brief 
low-level wind shear conditions in the St. Louis area through 14z 
due to a west-northwest wind Max of 35-40 kts from 1500-2000 ft 
above ground level.
