NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
352 am CDT sun Oct 26 2014 


Short term: (through late this afternoon) 
issued at 351 am CDT sun Oct 26 2014 


Temperatures will be the primary focus for today after fog...primarily 
confined to river valleys...dissipates by mid morning. Sfc observations 
over the past couple of hours have shown a slightly more pronounced 
southwestward push to the cooler/drier air. Consequently...did trim 
back high temps a degree or two for northeastern portions of the forecast 
area as retreat of frontal boundary back north may be a bit later 
during the day than previously thought. Latest 0000 UTC model guidance 
also supports this idea with warm front nearly bisecting the County warning forecast area by late 
afternoon. Regardless...still appears to be another unseasonably warm day 
across the bi-state region...especially the further south and west you 
travel. 




Gosselin 




Long term: (tonight through saturday) 
issued at 351 am CDT sun Oct 26 2014 




(tonight - Monday night) 


Unseasonably warm conditions to continue through the day on Monday 
as cold front begins to approach the region from the northwest. 
Went aoa warmest guidance for temps Monday as 850-hpa thermal ridge 
advects through the County Warning Area. High temperatures are expected to be in the 
80s areawide...will certainly continue to feel more like Summer than autumn. 
Precipitation chances will also begin to ramp up along/ahead of 
aforementioned cold front with chc pops for showers/thunderstorms entering 
northeast Missouri by late afternoon. 


Precipitation chances to continue to rampen up through Monday night as 
potent vort Max transverses the mid-Mississippi Valley. Increased pops 
for most of the area into the likely category as confidence in frontal 
timing/associated chances for showers/embedded thunder has increased. 
Cold front around 0600 UTC should nearly bisect the County Warning Area whereby 1200 UTC 
the front is expected to have passed off just to the southeast. 




(Tuesday - saturday) 


Rain chances will decrease rapidly behind fropa as dry/cool advection 
commences. Look for temperatures also to return to more normal values 
for late October as autumn makes a return to the region. Seasonal 
temps day/night should continue through Thursday before a reinforcing 
shot of colder air yields below normal temperatures for the end of the 
extended period. A potential frost/freeze still looks in the offing 
Saturday morning with lows in the l/M 30s. Depending on strength of 
the next airmass...temps may even be a bit colder.

Aviation: (for the 06z tafs through 06z Sunday night) 
issued at 1030 PM CDT Sat Oct 25 2014 


A surface ridge centered over Minnesota and Iowa will drop southeastward 
through Illinois late tonight. Light nely surface winds will veer 
around to an Ely direction late tonight. With a clear sky and 
light surface wind there may be some fog late tonight/early Sunday 
morning in cou, sus and cps where the surface dew points will be a 
little higher. The surface wind will strengthen from a sely 
direction on Sunday as the surface ridge shifts east of the area 
and a warm front approaches. There will likely be scattered 
diurnal cumulus clouds late Sunday morning and afternoon as the 
boundary layer moistens ahead of the warm front. 


Specifics for kstl: a clear sky and light surface wind late tonight. 
The surface wind will increase to 9-10 kts Sunday afternoon from a 
sely direction. There will likely be scattered diurnal cumulus 
clouds Sunday afternoon.
