NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
720 PM CDT Sat Sep 20 2014 


Short term: (through late tonight) 
issued at 335 PM CDT Sat Sep 20 2014 


Main question for tonight is the convective trends and evolution. 
The surface cold front is still far removed from the cwa, extending 
from central Iowa through southeast Nebraska into northern Kansas at 
mid afternoon. A fairly broad region of low level confluent flow is 
located ahead of the front from northern Illinois into northern MO and 
northeast Kansas where SBCAPE ranges from 1500-2500 j/kg. Convection 
allowing models differ considerably on evolution of storms and don't 
offer much support. The visible satellite is showing agitated cu 
within the confluent zone where the cirrus has been thinning. The 
shortwave tracking across the upper MS valley will bring some weak 
mid level cooling further reducing any cin, but large scale 
support is largely weak or non-existent. Present thought is that 
scattered thunderstorms will develop within this confluent zone 
during the later part of this afternoon and evening. Can't see 
much better than scattered coverage unless we see areas of 
storm/cold pool mergers. Greatest coverage should be this evening, 
waning overnight with loss of instability as the cold front moves 
southeastward through the area. 


Glass 


Long term: (sunday through next saturday) 
issued at 335 PM CDT Sat Sep 20 2014 


The cold front should exit southern portions of the County warning forecast area around 
12-15z on Sunday morning, thus ending the chance of precipitation 
across the area through at least the first half of the work week. 
Cooler and drier air filtering into the region in the wake of the 
front Sunday will yield highs up to 10 degrees cooler for some 
locations, with highs ranging from the low 70s north to near 80 
degrees over far southern zones. Northwest flow will persist over the 
region through the first part of the week as high pressure builds in 
over the central US, with highs Monday and Tuesday only reaching the 
low to middle 70s area-wide. Beginning Wednesday, temperatures will 
start to slowly rebound as surface high pressure drifts to the east 
allowing for southerly flow to return, with highs reaching the upper 
70s to around 80 degrees by Friday and Saturday. 


A low pressure system currently off the central California coast 
is still progged to come ashore and lift through The Rockies 
toward the north Central Plains by Tuesday night, though models 
differ on the behavior of the low from that point forward. The GFS 
and Gem both show the low retrograding southwestward prior to 
making any impact on our area, whereas the European model (ecmwf) absorbs it into 
the mean flow, lifting it quickly toward the upper Midwest and 
Great Lakes. This feature could bring some increased cloud cover 
and precipitation to northeast and mid Missouri in the Wednesday 
night/Thursday time frame, though confidence is low until future 
model runs come into better agreement. Other than this mid-week 
feature, the extended looks to be dry and seasonably cool through 
the start of next weekend.

Aviation: (for the 00z tafs through 00z Sunday evening) 
issued at 633 PM CDT Sat Sep 20 2014 


Scattered thunderstorms are possible this evening ahead of an 
approaching cold front, but coverage is expected to be limited. 
Winds will become northwesterly after fropa and gust to around 20 
kts tomorrow. Generally VFR conditions are expected outside of 
thunderstorms.
