NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
310 PM CDT Thu Apr 17 2014 


Short term: (through late tonight) 
issued at 306 PM CDT Thu Apr 17 2014 


Despite cold front moving through region, front is weakening and 
moisture is lacking so any precipitation will be very light in 
nature. So just have slight chance of showers for portions of west 
central/southwestern Illinois tonight. Otherwise, partly to mostly cloudy 
skies to begin scattering out late tonight. Not a lot of caa with 
this system, so lows will be in the mid 30s to mid 40s.

Long term: (friday through next thursday) 
issued at 306 PM CDT Thu Apr 17 2014 


Should have a clearing sky from northwest to southeast on Friday as 
the surface ridge builds into the area behind the weakening cold 
front, and as the upper level trough shifts east of our area. 
Tranquil and warmer weather heading into the weekend as an upper 
level ridge moves into the area on Saturday behind the upper level 
trough/low. Above normal high temperatures expected on Saturday and 
Sunday as southerly surface/low level flow returns. Low level 
moisture and instability will increase over our area Saturday night 
and Sunday due to the persistent southerly flow ahead of a slow 
moving shortwave over the Central Plains. Scattered showers and a 
few thundestorms will likely develop Sunday afternoon across MO, west 
of stl. Showers and a few storms should overspread our area Sunday 
night and continue on Monday as this weakening shortwave/upper level 
trough moves slowly eastward through the region, while a relatively 
weak cold front moves slowly southeastward through our area on 
Monday and Monday evening. The precipitation threat should shift 
southeast of our forecast area by late Monday night as the upper 
level trough shifts east of the region and a surface ridge 
builds southeastward into the area behind the cold front. Only 
slight and short lived cooling is expected behind the cold front, 
with pronounced warming expected Tuesday night and Wednesday as an 
upper level ridge moves eastward into the region and southerly low 
level flow returns and strengthens. The GFS model increases the 850 
mb temperatures to 12-16 degrees c by Wednesday night over our 
forecast area, whle the European model (ecmwf) is not quite as warm. The GFS model 
brings convection into northeast MO and west central Illinois Wednesday 
and Wednesday night due to strong low-mid level warm air advection 
ahead of "ridge runner" type shortwaves. There does seem to be some 
convectve feedback in the GFS model at this time leading to 
overamplified vort maxes and potentially too much convection 
depicted by the model, although the European model (ecmwf) also has some qpf 
extending south into this area as well.

Aviation: (for the 18z tafs through 18z Friday afternoon) 
issued at 1249 PM CDT Thu Apr 17 2014 


Weak cold front is making very slow progress to the south today. 
It has moved through KUIN and kcou, but is stalled over Metro 
area as of 17z. MVFR cigs at KUIN have scattered out. Otherwise, 
mid and high clouds prevail over region. As low level moisture 
increases, just a bit, will see low end VFR cigs develop north of 
frontal boundary late this afternoon and early this evening. 
Shower activity will be very sparse so did not add mention to tafs 
at this time. Otherwise, southwest winds to veer to the northwest 
to north behind the boundary, but remain rather light. Later 
tonight cigs to scatter out and winds become light and variable. 
Winds will pickup just a bit from the northeast on Friday as 
frontal boundary washes out and surface ridge builds in. 


Specifics for kstl:

north behind the boundary, but remain rather light. By 09z Friday 
cigs to scatter out and winds become light and variable. Winds 
will pickup just a bit from the northeast by 19z Friday as 
frontal boundary washes out and surface ridge builds in.
