NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
326 PM CDT Thu Oct 30 2014 


Short term: (through tonight) 
issued at 250 PM CDT Thu Oct 30 2014 


Focus this evening will be on pops. 


Sfc low continues to move thru the County Warning Area with light rain showers ahead of 
the low. At the current rate, the rain showers will be out of the County Warning Area 
around or by 00z. However, redevelopment will be possible, 
especially across ern portions of the County Warning Area as a secondary fnt 
pushes swd. The secondary fnt shud bring colder air, but 
additional clouds as well. This presents a bit of a forecast 
challenge for temps tonight. Overall, trended twd the cooler 
guidance across the north where clouds shud clear late tonight, and 
warmer further S where clouds shud linger and fnt may not arrive 
by sunrise tomorrow. While temps tonight will be around freezing 
across the nrn counties, do not anticipate a hard freeze and 
strong winds behind the fnt shud prevent any frost from forming.

Long term: (friday through next thursday) 
issued at 257 PM CDT Thu Oct 30 2014 


Sfc ridge builds into the region beginning Fri. With no precip 
expected, focus turns to temps thru the weekend. 


Mdls are in good agreement thru the weekend with the sfc ridge 
settling just northwest of the County Warning Area Fri night, then to the southeast on Sat 
night. This shud allow ample radiational cooling across the region 
with a clear sky for nearly the entire night. Have upgraded the 
freeze watch to a warning for the entire County Warning Area as confidence 
continues to build. Note that if this warning verifies across the 
cwa, this will end the freeze/frost headlines for the County Warning Area this 
year as the growing season has come to a close. 


Mdls remain in fairly good agreement with the next cdfnt to impact 
the region. Latest guidance suggests precip develop/enter the County Warning Area 
Mon afternoon and persist thru much of the day tues and into tues 
evening as the slow moving cdfnt pushes thru the area. 


Not much in the way of cold air is currently expected behind this 
fnt. Some differences exist among mdl guidance regarding temps 
behind this fnt. For now, have trended twd a compromise.

Aviation: (for the 18z tafs through 18z Friday afternoon) 
issued at 1222 PM CDT Thu Oct 30 2014 


The back edge of a large area of showers currently extends from 
KUIN to just west of kcou at midday. These showers will continue 
moving to the east through the afternoon impacting the St. Louis 
area terminals with light rain showers and VFR conditions. The 
precipitation should be east of all taf sites by 23z. A cold front 
will then pass through the area this evening with a big increase 
in northwest winds overnight accompanied by a period of MVFR cigs. 
The cigs should clear out on Friday morning with gusty northwest 
winds continuing well into the afternoon. 


Specifics for kstl: 


Light rain showers accompanied by VFR flight conditions will 
impact the terminal this afternoon and should exit to the east by 
23z. Thereafter a cold front will move through this evening with a 
big increase in northwest winds overnight, accompanied by a period 
of MVFR cigs beginning around 11z. The cigs should clear out near 
15z Friday morning with gusty northwest winds continuing well into 
the afternoon.
