Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
538 PM CST Wed Jan 28 2015 


Short term: (through late tonight) 
issued at 402 PM CST Wed Jan 28 2015 


Shortwave over the Nebraska Panhandle and eastern Colorado and associated 
surface low ahead of it over eastern Nebraska will move eastward 
through northern MO and southern Iowa tonight. The surface low will 
drag a cold front southeastward through our forecast area late 
tonight and Thursday morning. Most of the models have the 
precipitation north of the surface low track, although the European model (ecmwf) 
model does generate light qpf across Illinois already this evening in the 
warm air advection regime ahead of the shortwave. The models were 
also depicting upper level divergence centered over northeast MO and 
west central IL, mainly late tonight in the left exit region of an 
upper level jet streak dropping into southwest MO. The quality and 
depth of moisture is quite limited with this system so will only 
include slight chance pops across west centrl and southwest IL, 
mainly late tonight into Thursday morning. A tight surface 
pressure gradient along with a strong southwesterly low level jet 
will lead to relatively strong surface winds for the nightime 
hours. Low temperatures will be above normal tonight as the strong 
cold air advection behind the front will not impact most of the area 
until Thursday morning. 


Gks 


Long term: (thursday through next wednesday) 
issued at 402 PM CST Wed Jan 28 2015 


Colder conditions are expected on Thursday due to low level cold air 
advection with strong and gusty northwest winds behind the cold 
front, along with Post frontal low level cloudiness to limit solar 
insolation. Little diurnal temperature range is expected with some 
areas likely having nearly steady or slightly falling temperatures 
during the late morning and afternoon hours. These clouds should 
clear out Thursday night as subsidence increases over our area as a 
strong surface ridge over the northern plains builds southeastward 
into the region. Cold conditions will continue Thursday night and 
Friday with near normal temperatures for late January. 
Precipitation is expected to spread into our area by Saturday 
afternoon and evening as moisture spreads into our region ahead of 
the southwestern US upper level low, and as a strong northern stream 
shortwave approaches from the northern plains. Initially it appears 
that surface temperatures will be warm enough Saturday afternoon 
into the evening that any precipiation at this time should fall as 
liquid rain. As a cold front sags southward through our forecast 
area Saturday night into Sunday as the upper level trough gradually 
deepens over the northern plains and Great Lakes region the 
precipitation should change over to snow. The European model (ecmwf) model has most 
of its quantitative precipitation forecast along and south of I-70 Saturday night and Sunday. The 
GFS is similar although it does have a little more qpf across 
northern MO and west central Illinois compared to the European model (ecmwf). There has 
been plenty of model differences along with run to run 
inconsistencies with this weekend storm system and hence it has been 
difficult to determine precipitation amounts and types across our 
area. For now it does appear that at least a portion of our 
forecast area will see accumulating snow Saturday night and Sunday, 
but the snowfall amounts and where the maximum axis of snow will 
occur is still in question. Much colder, below normal temperatures 
can be expected for Sunday night through Monday night with the 
models dropping the -12 degree c 850 mb isotherm southward into our 
forecast area Sunday afternoon. Monday and Tuesday will likely be 
dry as snow associated with northwest flow shortwaves should be 
north of our area, and any precipitation associated with the 
southwest US upper level low finally moving eastward through the 
Southern Plains and Gulf Coast region will be well south of our area.

Aviation: (for the 00z tafs through 00z Thursday evening) 
issued at 525 PM CST Wed Jan 28 2015 


Next weather system will move through the bi-state area overnight 
tonight. Terminals are expected to remain dry but impacts include 
some low-level wind shear tonight along with some MVFR ceilings 
behind the passage of the cold front. Wind gusts will subside this 
evening before ramping back up late tonight/early Thursday after 
frontal passage as winds become northwesterly. Ceilings are 
expected to gradually lift during the day on Thursday before 
scattering out by afternoon.
