National Weather Service St Louis MO 
1114 PM CDT Sat Oct 25 2014 


Short term: (through monday) 
issued at 332 PM CDT Sat Oct 25 2014 


Although it's hard to believe based on afternoon temperatures in 
the mid-70s to lower 80s, a weak cold front did move into the County Warning Area 
earlier this morning before stalling out. A surface high moving 
through the western Great Lakes will nudge the stalled front a bit 
farther south tonight before the boundary lifts back northeastward 
as a warm front. A band of clouds may accompany the warm frontal 
passage late tonight and tomorrow, although cloud cover should be 
greater over the plains compared to eastern MO and western Illinois. 
Some fog is also possible overnight ahead of the surface front, 
mainly in central MO and parts of the Eastern Ozarks, because dew 
points should be a bit higher there compared to areas which will 
still be under the influence of the surface ridge and its drier 
air. Unseasonably warm temperatures (15-20 deg above average) are 
expected again on Sunday and Monday.

Long term: (monday night through next saturday) 
issued at 332 PM CDT Sat Oct 25 2014 


A low pressure system was noted off the California/or coastline this 
morning, and this system will ultimately bring a chance of 
widespread rain to the area on Monday night and Tuesday. Models 
depict a few hundred j/kg of MUCAPE on Monday night, which should 
be sufficient for a few embedded thunderstorms. Comparatively 
speaking, a much cooler air mass will then spread across the 
region on Tuesday and Tuesday night, ending the recent string of 
unseasonably warm October days. 


Isolated to scattered showers are possible on Wednesday night into 
Thursday due to lift ahead of a shortwave which will be moving 
through northwest flow.

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.
