NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1157 PM CDT Thu Oct 30 2014 


Update: 
issued at 944 PM CDT Thu Oct 30 2014 


The light showers which have been moving through southeast MO and 
southwest Illinois should shift southeast of our forecast area by 
midnight. Patchy light rain, mainly sprinkles will move 
southeastward through mainly the Illinois counties of our forecast area 
late this evening and overnight. This activity is associated with 
another northwest flow shortwave and a secondary cold front. Post 
frontal low level cloudiness across the northern plains will 
advect southeastward into our area later tonight. Surface winds 
will become northwesterly and strengthen behind the second cold 
front, bringing much colder air into our area. This strong cold 
air advection late tonight will lead to below normal temperatures 
across northeast MO with temperatures dropping to close to 
32 degrees in this area by 12z Friday.

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. 


Tilly 


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 06z tafs through 06z Friday night) 
issued at 1157 PM CDT Thu Oct 30 2014 


VFR conditions and dry weather will prevail at the taf sites thru 
much of the valid period. A weak area of low pressure just west of 
the stl Metro area, resulting in light and variable winds with 
strengthening winds in its wake out of the north-NW, will drop 
southeast allowing a secondary cold front in later tonight. The 
only exception to the VFR looks to be with a period of lower cigs 
following the secondary cold front. Another potential pitfall with 
non-VFR is a period early on of fog with weak winds, mostly clear 
skies and low dewpoint depressions over the stl Metro area, but 
increasing winds, drier air, and clouds very soon should nullify 
that possibility. There is also some small potential for light 
sprinkles with the lower cigs when they do move in, but left dry 
in the tafs. Otherwise, look for a substantial increase in winds 
from the north-northwest later tonight with this second front and this should 
persist thru Friday with clouds scattering out Friday morning, and 
then a diminishing around sunset. 


Specifics for kstl: VFR and dry thru much of the valid period. 
Exception will be late tonight with MVFR cigs expected and perhaps 
a few sprinkles as well. Gusty north-northwest winds will move in about the 
same time as the lower cigs and should persist thru the day on 
Friday--only diminishing toward sunset.
