NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service St Louis MO 
754 PM CST Fri Dec 19 2014 


Update: 
issued at 734 PM CST Fri Dec 19 2014 


Fog was starting to develop over western MO this evening. Although 
no drizzle has been reported yet across our area, conditions will 
remain favorable for fog and light drizzle overnight. The going 
forecast looks on track with only minor adjustments required. 
Updated grids and products have been sent.

Short term: (through late tonight) 
issued at 309 PM CST Fri Dec 19 2014 


Shortwave energizing southern stream system over the Gulf Coast is 
spreading some mid and high level cloudiness across our region 
this afternoon. Regional radar mosaic is indicating some very 
light echoes associated with this cloud deck slowly working their 
way from N Arkansas into se MO, so will continue the mention of flurries 
in our far southeast counties into the early evening hours. 


Otherwise, broad area of low level moisture remains locked on SW 
periphery of the surface ridge that stretches from the Great Lakes 
into the lower Ohio Valley, and this low level moisture should 
keep skies cloudy over most of the region even after the passage 
of the aforementioned shortwave. A secondary shortwave is progged 
to drop from the mid MO valley after midnight tonight, producing 
some weak low level warm air advection advection over western sections of the 
County Warning Area. However, forecast sounding suggest that moisture will remain 
stratified in the lowest few thousand feet of the air mass with very 
little moisture in layer that would allow for ice nuclei to form. 
Therefore, any precip associated with the broad area of lift and 
warm air advection would likely be in the form of drizzle, much as suggested by 
going forecasts. Temperatures aren't expected to drop more than a 
few degrees from their current levels, but latest forecast of 
hourly temp trends suggest that some freezing drizzle will be 
possible in northern parts of the fa, primarily along and north of 
a Shelbina-Bowling Green line. Relatively warm ground temps (mo ag 
site at Novelty has 2-4" soil temps between 32-35) and Road 
treatments from yesterday's light snowfall should mitigate most 
problems if freezing drizzle does form, but obviously we will be 
monitoring this threat. 


Truett 


Long term: (saturday through next friday) 
issued at 309 PM CST Fri Dec 19 2014 


Expect quiet weather this weekend with a gradual warming trend 
from Saturday through Monday. A compact vort Max moving from Iowa 
into Illinois on Saturday might support light drizzle during the morning 
hours. 


Precipitation chances increase on Sunday night into Monday ahead of 
a clipper-like system which will be developing over the northern 
plains and eventually closing off over the central or eastern Continental U.S.. 
this system will probably bring periods of rain to the area from 
Monday through Tuesday, especially on Monday (central mo) and 
Monday night (eastern MO and western il). Cooler temperatures are 
expected behind Monday night's cold front, and this may cause the 
rain to mix with snow at times. Light snow could linger into 
Wednesday, depending on how quickly the system moves away from the 
area. 


A brief period of shortwave ridging is anticipated during the middle 
to late part of the week ahead of a developing low pressure system 
which could bring widespread rain/snow to the area next 
Friday/Friday night. The model solutions which depict low pressure 
systems at these extended time ranges often undergo several 
changes, therefore there is low confidence in the timing/location 
of any precipitation for late next week.

Aviation: (for the 00z tafs through 00z Saturday evening) 
issued at 559 PM CST Fri Dec 19 2014 


Extensive area of MVFR and IFR conditions across the western two 
thirds of Missouri will expand eastward later this evening, 
reaching the St. Louis Metro taf sites and KUIN between 04-06z. 
Then expect IFR ceilings to develop overnight at kcou and KUIN. 
Still expect 2sm visibilities to reach ksus in the Missouri River 
valley. Think just MVFR conditions will occur at kstl and kcps. 
These conditions will then likely persist through the morning 
hours before there is some improvement by early afternoon. 


Specifics for kstl: believe going taf has a good handle on current 
situation as a dry easterly wind will likely keep conditions VFR 
this evening. Then expect MVFR ceilings that are currently just 
west of the terminal to move into kstl overnight and persist 
through Saturday morning with ceilings rising above 2000ft by 
midday.
