NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1147 PM CDT Thu Apr 24 2014 


Short term: (through late tonight) 
issued at 234 PM CDT Thu Apr 24 2014 


(tonight) 


Main focus through tonight will be cold front and associated risk for 
showers and thunderstorms. Degree of instability is still a concern and 
a source of uncertainty. Dewpoints have really struggled to climb so 
far today due to persistent southeasterly surface flow. Winds are expected 
to veer to the south/southwest as a subtle warm front lifts north to near 
the I-70 corridor by 0000 UTC this evening. This should allow sfc dewpoints 
to at least climb into the 50s across the southern half of the area. That 
being said...instability is likely to be on the marginal side for severe 
thunderstorms...on the order of several hundred j/kg. Wind shear will be 
supportive however of organized convection over the southern County Warning Area with 
40+ knots of 0-6 km shear just downstream of approaching shortwave trough. 
Regardless of the severity of storms tonight...believe widespread showers 
and thunderstorms will affect the entire County Warning Area due to very strong forcing for 
ascent aloft via dcpva ahead of vort Max and jet coupling. This strong 
upper-level support may help overcome the lack of instability and may 
lead to more strong/severe storms with damaging straight-line winds being 
the primary threat. Frontal timing and associated ending to precipitation 
is even more delayed than this time yesterday...with frontal timing just 
after 0000 UTC likely along the Mississippi River including the St. Louis 
metropolitan area and around 0400 UTC for kslo/k3lf. 


Skies will quickly clear overnight tonight with northwesterly winds gradually 
lightening up a bit. Look for lows in the 40s to near 50 degrees across the 
area and went with a consensus of guidance for mins tonight.

Long term: (friday through next thursday) 
issued at 240 PM CDT Thu Apr 24 2014 


With sfc ridge building into the region on Fri, have continued 
warm trend aoa MOS thru Sat. 


Mdls remain in relatively good agreement regarding the system 
approaching the area on sun into Mon. A lot can change by sun and 
will not focus much on details, but sun and/or Mon will have a 
potential for svr wx. Timing differs among mdl guidance, but GFS 
suggests main threat will be sun, while the European model (ecmwf) suggests the 
threat continuing into Mon. 


For tues and beyond, large upper low will remain anchored over the 
region thru much of the week. Will need to keep an eye on temps 
during this time as going forecast may be too cold. While this 
period shud be cooler, expect cloud to become bkn during the 
morning and into afternoon allowing low topped convection to occur. 
For now, will trend near a guidance compromise.

Aviation: (for the 06z tafs through 06z Friday night) 
issued at 1141 PM CDT Thu Apr 24 2014 


The cold front will pass through the St. Louis Metro area between 
05-06z accompanied by MVFR and occasionally IFR cigs, light rain 
and gusty NW winds. Clearing has just occurred at kcou and should 
occur around 07z at KUIN and the St. Louis terminals between 
09-10z. Thereafter VFR flight conditions/clear skies will 
dominate with surface winds backing from northwesterly early 
Friday morning to southwesterly by Friday afternoon. 


Specifics for kstl: 


The cold front will pass through the terminal between 05-06z 
accompanied by a period of MVFR and occasionally IFR cigs, light 
rain and gusty NW winds. Clearing should occur around 09z. Thereafter 
VFR flight conditions/clear skies will dominate with surface 
winds backing from northwesterly early Friday morning to 
southwesterly on Friday afternoon.
