NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
issued by National Weather Service Kansas City/Pleasant Hill MO 
354 PM CST Thu Feb 26 2015 


Short term: (through late tonight) 
issued at 327 PM CST Thu Feb 26 2015 


Cold air continues to filter into the area as a strong surface 
ridge noses into the area. The final glimpses of light snow 
flurries are coming to an end near the St. Louis Metro area, with 
maybe another hour or two before the snow completely cuts off. 
Regardless of how much longer the flurries continue, further 
accumulations through the evening are very unlikely, so have 
generally trended pops downward through the rest of the evening. 
Overnight lows will be rather chilly as the surface high moves 
overhead, with temperatures on Friday morning reaching between 0 
and 10 degrees along and south of I-70, with temperatures between 
0 and -5 across areas north of I-70. With the new snow pack over 
far northern Missouri and good radiational cool and little to no 
wind, there could be few isolated spots dropping to between -5 and 
-10 over far northern Missouri and Illinois. Since the surface 
high will be overhead for the night expect winds to drop off to 
around 0 to 5 mph, especially over the snow pack where the surface 
ridge will be more centered. This will help keep the wind chill 
values from plummeting too much. With wc values generally in the 
-10 to -15 range in far north Missouri and Illinois have opted to 
forgo a Wind Chill Advisory for that area, at least for now. Will 
let the evening and midnight shift take one more look at it. 


Long term: (friday through next thursday) 
issued at 327 PM CST Thu Feb 26 2015 


With the cold air solidly in place over the are it will set the 
stage for a winter system to affect a large portion of the 
forecast area for the weekend and again early next week. Broad 
troughing over the northern part of the Continental U.S. Will bring mostly 
zonal mid level flow over the forecast area. As a more potent area 
of low pressure energy digs into the West Coast a low level trough will 
take form over the interior mountain west and start a flow of warm 
air advection into the area. With the warm/moist air 
isentropically lifting over the cooler air in place it will 
gradually re saturate the atmospheric column and start to 
precipitate Saturday afternoon to evening across central Missouri 
and probably Saturday night for eastern Missouri and western 
Illinois. Since the thermal profile will be very cold, expect this 
activity to be all in the form of snow. At least for now it does 
not appear that p-type will be in much question, especially for 
the Saturday night period. At this time it does not appear that 
there will be much in the way of heavy snow, but the prolonged 
nature of the warm air advection, as the low stays anchored over 
the West Coast will provide at least 24, and perhaps 36 hours of 
very light snow, which will likely accumulate several inches 
through the weekend. Right now the models still favor a track of 
the higher snow amounts to be generally along and north of 
Interstate 70, and this makes sense since this corridor will have 
the better chance to maintain a cool enough thermal profile to 
keep everything snow. Farther south, in southern MO and Illinois there 
is a chance that some warmer low level temps could creep into the 
thermal profile, which would maybe cause some mixed precip types 
on Sunday. Given some lingering model discrepancy the confidence 
on specific amounts in a given location are still somewhat low to 
medium, however it does appear that areas along and north of I-70 
will see several inches of accumulating snow, perhaps getting up 
to 4 to 6 inches. As stated above, Standard uncertainty caveats 
apply, so amounts and locations will likely shift as we approach 
the event. 


The focus then shifts to early next week as another wave of energy 
ejects out of the Desert Southwest and into the forecast area. 
This trough will be a bit more potent than the weekend system, and 
will likely draw in more low level warm air and more moisture. At 
this point both ec and GFS would hint toward a large portion of 
the forecast area, especially areas south of I-70 getting mostly 
rain, with a few hours on either side of the rainy period of 
wintry mix as the thermal column warms up. Confidence is rising 
that there will be at least a decent amount of precipitation over 
a widespread area through the early to mid week period, but again, 
thermal column uncertainty will preclude any hard amounts and 
locations for any specific precip type. By late next week another 
strong cold front will sweep through and scour out the moisture, 
effectively ending chance for pops and ushering another cool down 
for the end of next week.

Aviation: (for the 18z tafs through 18z Friday afternoon) 
issued at 1126 am CST Thu Feb 26 2015 


Radar trends and most recent soundings indicate another few hours 
of very light snow, with likely VFR/MVFR visibility at the St. Louis 
terminals. Gradual improvement with visibility with time as the snow 
moves out, then MVFR ceilings for several more hours after that, with 
gradual improvement in the ceilings overnight. 


Specifics for kstl: light snow will move through over the next few 
hours, with gradual improvement in vsby, however ceilings will remain 
MVFR for several more hours. Soundings indicate possible thin MVFR 
stratus in the 24-30 hour time frame, but low confidence would 
preclude any mention for now.
