NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
611 PM CDT Fri Oct 31 2014 


Short term: (through tonight) 
issued at 110 PM CDT Fri Oct 31 2014 


Focus tonight continues to be temps. 


No changes to ongoing headline. If going forecast verifies, this 
will end the frost/freeze headlines for the year. Going forecast 
remains reasonable given the latest guidance and have made only 
minor changes. With winds remaining stronger across the ern 
portions of the cwa, temps will be slow to drop. However, with 
continued cold air advection and with winds diminishing quickly twd sunrise, 
believe the going forecast is still on track. Only other change is 
reducing the amount of frost mentioned in the forecast. With very 
dry air being advected swd and at least some wind remaining thru 
the night, believe frost will be more limited to sheltered areas. 


Tilly 


Long term: (saturday through next friday) 
issued at 255 PM CDT Fri Oct 31 2014 


Have trended twd the warmer guidance thru the weekend. Ample 
insolation shud help raise temps even with little to no warm air advection. 
Overnight temps trend warmer as well as the sfc ridge builds ewd 
and sly flow returns to much of the area. The only exception is 
sern portions of the County Warning Area tomorrow night where the sfc ridge will 
be overhead. For this area, have trended twd the cooler guidance. 


Focus turns to precip chances for Mon thru tues. Mdls remain in 
good agreement with this system and have gradually sped up timing 
of fropa late Mon into tues. Have moved up pops accordingly. 
Beyond this system, mdl solns diverge quickly. With drastically 
different solns late next week, have low confidence in either the 
European model (ecmwf) or GFS. For now, have kept pops low and have trended twd a 
compromise for temps.

Aviation: (for the 00z tafs through 00z Saturday evening) 
issued at 542 PM CDT Fri Oct 31 2014 


Few cumulus clouds in the St Louis Metro area will dissipate 
early this evening due to the loss of daytime heating, and as 
subsidence continues to increase as the strong surface ridge 
extending from Minnesota south into northeast Kansas and northwest MO shifts 
slowly southeastward. Strong and gusty N-nwly surface winds will 
gradually diminish through the night as the surface pressure 
gradient relaxes. The surface wind will become E-sely in uin and 
cou by late Saturday afternoon, and nely in the St Louis Metro 
area as the surface ridge axis shifts southeastward through the 
taf sites, albeit the wind will be quite weak by this time. 


Specifics for kstl: few clouds at 5000 feet will dissipate early 
this evening. Gusty nwly surface winds will diminish through the 
night. The wind will veer around to a nely direction by late 
Saturday afternoon and then sely by late Saturday evening, albeit 
quite light by Saturday evening. There may be some high level 
clouds Saturday afternoon and evening.
