Severe Weather Alert Descriptions

 Special Statement  Statement as of 4:05 am CST on February 1, 2015


... Light snow accumulations expected this morning from central and
east central Missouri into southwest Illinois...

Rain has become mixed with and changed to snow over sections of
central and east central Missouri into southwest Illinois this
morning. Some minor accumulations of over an inch are possible.
This snowfall will be brief... as warmer air working back into the
area will turn the snow back to rain early this morning... and
likely melting most if not all of the snow.

Early morning motorists should slow down if encountering snow
covered roads... and use extra caution when approaching bridges and
overpasses.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
458 am CST sun Feb 1 2015 


Short term: (today and into this evening) 
issued at 419 am CST sun Feb 1 2015 


Precip is blanketing the County Warning Area early this morning in the zone of 
strong warm air advection ahead of surface low...currently over east central Kansas. 
Low is expected to track just a bit north of east, and our 
forecast takes the low to near KUIN by 18z. Heavy snow has been 
falling over our extreme northern counties since late Saturday 
evening. Although ground truth has been hard to come by overnight, 
it appears 6+ inches has already fallen over Knox County. However, 
the snowfall gradient appears to be quite sharp, with only a few 
inches one or two counties south. It would appear that most of the 
precip in this area will remain as snow today, although with 
surface low getting so close it's certainly possible that the snow 
could Switch Back to some rain for a bit around midday before the 
cold air and strong north winds in the wake of the low changes the 
precip back to all snow. Based on the snow that has already fallen 
and the expected snow today and into this evening, decided to 
expand the Winter Storm Warning into Shelby and Marion counties. 
By the time the snow winds down this evening, some locations in 
Knox and Lewis counties should have snowfall totals around 10 inches. 
In addition to the snow, falling temperatures and increasing 
northerly winds are expected in the warning area during the 
afternoon. Since much of the snowfall today will be fairly wet 
don't expect too much of a blowing snow problem, although the snow 
that falls late today will be much more prone to being moved 
around as it should be much "lighter". 


While the forecast for our north is fairly clear cut, it is a 
muddled mess over the central third of the County Warning Area. Evaporative 
cooling has dropped the freezing level enough to turn the rain 
over to snow from mid MO to just west and northwest of stl Metro. However, 
as the surface low tracks east this morning warmer air will 
return to this part of the forecast area and change the snow back to rain 
and likely melting any early day accumulation, with cold advection 
then transitioning precip during the mid-late afternoon back to 
snow from mid MO to just north of stl. Briefly considered expanding 
the advisory to cover some of this morning snowfall, but given the 
expected warmup and change back to rain decided to issue an Special Weather Statement to 
cover this area and maintain the southern edge of the advisory from 
Monroe into Pike County Illinois...where ptype will likely remain snow 
and snowfalls should be higher. 


Expect some light snow with minor accumulations to linger over the 
northwest two-thirds of the County Warning Area into the early evening, with the 
snow ending or tapering off to flurries by midnight. The cold air 
surging south behind the storm will make for a windy and cold 
night, with temperatures bottoming in out in the single digits and 
teens by Monday morning. 


Obviously, this is a very tricky forecast, and short term trends 
could force adjustments to headlines as the day progresses. Will 
also need to keep an eye on the impact of light snow and sharply 
falling temperatures on the wet roadways as we head into the early 
evening hours.

Long term: (monday through saturday) 
issued at 419 am CST sun Feb 1 2015 


Going forecast through midweek looks pretty good, so only a few 
minor changes were made to going trends. In general. Expecting a 
cold day on Monday, with a brief moderation on Tuesday followed by 
another surge of cold air by Wednesday. There is some 
some uncertainties on timing and placement of precipitation on 
backside of the cold front with GFS faster than the European model (ecmwf). For 
now will side with the faster GFS and keep slight chance/low 
chance pops for northern half of forecast area on Wednesday, then 
spread south across rest of forecast area Wednesday night with 
some accumulating snow possible with this system. Then dry and 
moderating temperatures expected for the last part of the work 
week and into next weekend.

Aviation: (for the 06z tafs through 06z Sunday night) 
issued at 1121 PM CST Sat Jan 31 2015 


Specifics for kuin: an air temperature of around 34 degrees has been 
sufficient for the transition from rain to snow, and various 
processes in the atmosphere continue to keep the temperature 
fluctuating through the low to mid 30s, which is causing the ptype 
to unpredictably Switch Back and forth between rain and snow. With 
time, the ptype should become predominantly snow. I have attempted 
to convey this complexity in the taf. Several inches of 
accumulating snow are expected at the terminal, but some of the 
snow could melt during periods of rain. Winds will swing around to 
the northwest and become quite gusty during the afternoon and 
evening hours. 


Specifics for kcou: precipitation was starting to reach the ground 
at kcou at taf issuance. An air temperature of around 34 degrees 
has been sufficient for the transition from rain to snow over the 
last few hours around the region. Various processes are causing 
the temperature to fluctuate through the low to mid 30s, therefore 
the ptype can Switch Back and forth between rain and snow 
unpredictably. It is possible that a solid changeover to snow at 
kcou may not occur until the colder air arrives with the cold 
front on Sunday. Winds will swing around to the northwest and 
become quite gusty during the afternoon and evening hours. 


Specifics for kstl, ksus, kcps: dry air has been holding its own 
over the last several hours (as per the donut hole on radar over 
klsx and the 20 degree dewpoint depressions at kstl/ksus/kcps). 
Precipitation has been slower to reach the ground at St. Louis 
Metro area taf sites than previously anticipated, so I backed off 
on the rain by a couple of hours. The overall thinking is that 
precipitation will be predominantly rain overnight and for most of 
Sunday. It will take the arrival of the cold front on Sunday 
afternoon to start changing the rain over to snow. Winds will 
swing around to the northwest and become quite gusty between 
02/00z and 02/03z.
