NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
553 PM CDT Wed Oct 22 2014 


Short term: (tonight and thursday) 
issued at 328 PM CDT Wed Oct 22 2014 


The surface ridge which has been controlling our weather for the 
past couple of days is drifting east and weakening slightly with 
time. Water vapor imagery is showing an elongated wave extending 
from Saskatchewan all the way south into West Texas. This wave will 
continue working slowly eastward overnight and should extend from 
south central Iowa southwest through eastern Oklahoma by 12z 
Thursday morning. Operational guidance is pretty Adamant that there 
will be little if any precip east-southeast of Kirksville in our 
area before 12z, with precip chances ramping up during the daylight 
hours Thursday morning. Scattered to isolated showers probably 
won't get into east central Missouri, but central and northeast 
Missouri and west central Illinois should see some light showers in 
the morning. Rain chances diminish Thursday afternoon as the wave 
loses some potency, and drier low level air on the western side of 
the stubborn surface ridge cuts into the showers. MOS guidance 
looks reasonable for both highs Thursday afternoon and lows tonight. 


Carney 


Long term: (thursday night through next wednesday) 
issued at 402 PM CDT Wed Oct 22 2014 


Any lingering showers should be exiting the area along with the 
shortwave by 00z Friday or shortly thereafter. Another upper level 
ridge builds over The Rockies and across the Great Plains Friday 
into Saturday. Northwest flow aloft will prevail both days while a 
weak cold front tries to dip into Missouri and Illinois. The upper 
ridge will move over the Midwest on Sunday allowing another high 
pressure system to move into the Ohio Valley. The western edge of 
the airmass keeps edging further and further west with each model 
run. Have lowered temperatures a bit from the last couple of 
forecasts, tho have tried to keep highs Sunday warmer than guidance, 
and retained warmest temperatures over west/southwest sections of 
the County warning forecast area. 


A full-latitude trof moves into the Great Plains Monday which will 
bring broad south-southwest flow to the region and warm temperatures 
in the mid to upper 70s. The surface system associated with the 
trof will gain strength and affect the area Tuesday into Wednesday. 
Some discrepancies with the medium range models out that far, but 
high chance pops ahead of the cold front on Tuesday look 
reasonable. Position and speed of the system will determine whether 
or not there will be thunderstorms, but a slight chance is not out 
of the question.

Aviation: (for the 00z tafs through 00z Thursday evening) 
issued at 531 PM CDT Wed Oct 22 2014 


Surface ridge extending from Michigan southwest through southeast MO 
will shift slowly southeastward this period. An upper level 
disturbance and associated weakening cool front/surface trough 
will move eastward through the region on Thursday. Most of the 
precipitation associated with this feature will be N-NW of the taf 
sites, although uin may receive a brief shower late Thursday 
morning or early afternoon. For now will just include some mid- 
high level cloudiness in the tafs for Thursday. The NAM MOS 
guidance appears a little overdone on its low level cloud 
forecast. East-sely surface winds will veer around to a sly direction 
Thursday morning. 


Specifics for kstl: mid-high level cloudiness will advect into the 
stl area on Thursday. Any significant rain should remain N-NW of 
stl. A light E-sely surface wind tonight will gradually veer around 
to a sly direction Thursday morning, and eventually to a swly 
direction Thursday evening.
