NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service St Louis MO 
942 PM CST Sat Jan 31 2015 


Update: 
issued at 936 PM CST Sat Jan 31 2015 


Band of moderate to heavy snow has developed over the past couple 
of hours yielding 2-4+" across portions of north-central and 
northeast Missouri...including around 2 inches in Edina and 
Novelty in Knox County as of 900 PM. Based on radar 
imagery...believe this to persist through at least 0600 UTC. After 
that time frame...did not deviate too much at all from previous 
forecast as fear that lighter precipitation rates may yield areas 
currently recieving snow to mix with if not outright change back 
over to rain. However...long fetch of dry low-level air will 
continue to advect into the region which may keep things all snow. 
If this does indeed occur...snowfall totals may need to be further 
boosted. Further to the south and east...dropped pops 
significantly due to aforementioned dry low levels and have pops 
ramping up as shield of precipitation slowly moves in from western 
Missouri. Updated zones out and west-southwest shortly.

Short term: (through Sunday night) 
issued at 324 PM CST Sat Jan 31 2015 


No changes to current headlines. Focus continues to be the system 
approaching the County Warning Area thru sun. 


Mdl solns continue to trend warmer tonight and into sun. The 
rap/hrrr solns are the warmest, suggesting the entire County Warning Area remains 
warm enuf for rain thru at least midnight tonight. The Gem being the 
coldest with the NAM/local WRF/European model (ecmwf) only slightly warmer. These 
cooler solns also suggest the 850 mb 0 degree c isotherm remains S 
of the 850mb low track. Believe this is the result of two features. 
First, adiabatic cooling due to dynamic lift across the region and 
second, evaporative cooling, albeit not much, at the onset of 
precip. The column quickly becomes saturated this evening with the 
current precip shield moving newd across thru the area, eliminating 
the second issue. 


Question then turns to if the very strong warm air advection/frontogenetical 
forcing can overcome the cooling due to lift and cause precip to 
either turn back to or mix with rain late tonight. Forecast soundings 
across the nrn portions of the County Warning Area continue to show the lowest 2kft 
to be at or just below 0c. The bl will remain as-is thru the morning 
hours as the 850 mb low. By 18z sun, cold air advection quickly takes over the nrn 
third to half of the County Warning Area. However, as the main trof digs and the 
system deepens, much of the County Warning Area is dry-slotted and bulk of the 
remaining precip is due to the def zone. 


Some questions remain with this system increasing the uncertainty. 
Mdls have come in with more qpf, esp later tonight. If these higher 
quantitative precipitation forecast amnts and colder solns verify, the going forecast may be too 
low. With a few minor tweaks, overall, snowfall forecast is very 
close to the prev forecast. 


Long term: (monday through next saturday) 
issued at 324 PM CST Sat Jan 31 2015 


(monday-tuesday) 


The work week will start off on a cold note featuring much below 
average temps with cyclonic flow and lots of remnant stratus early 
Monday morning. The low clouds however should clear southward during 
the morning as high pressure builds into the area. By afternoon warm 
advection aloft is already underway and heights are rising in the 
wake of the departing upper trof. This will be accompanied by lots 
of high clouds overspreading the region from afternoon and 
continuing into Monday night as the surface high retreats. The pick 
day of the week should be Tuesday with a strong warm advection 
regime forecast. This should result in a brief bump in highs to 
above normal readings. The exception is possibly across far 
northeast Missouri into west central Illinois where there will be 
snow cover and a bit of high cloudiness. 


(Wednesday-saturday) 


Cold weather and below average temperatures will once again take 
hold during the later part of the upcoming week. The flow aloft 
initially across much of the conus will be broadly cyclonic anchored 
by an upper vortex in the northern Hudson Bay region. A pronounced 
shortwave migrating through this flow aloft will send a rather 
strong cold front through the area late Tuesday night-early 
Wednesday. The biggest uncertainties during the extended forecast 
time frame deal with the Wednesday-Wednesday night period in the 
wake of this front. The GFS and CMC Gem both have another 
progressive disturbance lagging in the cyclonic flow. They both 
suggest that this disturbance and the associated forcing and 
resultant frontogenesis will produce a Post-frontal WNW-ESE oriented 
band of accumulating snow. The European model (ecmwf) on the other hand lacks this 
scenario and has high pressure dominating, however suggests a warm 
advection snow band may occur Thursday. At this point I have a 
little more confidence in the GFS/Gem solution albeit low, and will 
continue with some low pops. 


By the beginning of the next weekend, heights aloft are rising as 
the mean longwave trof axis shifts off the eastern Seaboard and warm 
advection is underway signaling moderating temperatures.

Aviation: (for the 00z tafs through 00z Sunday evening) 
issued at 519 PM CST Sat Jan 31 2015 


Specifics for kuin: a winter storm system will affect west central 
Illinois through Sunday. As the colder air arrives overnight, rain will 
change over to snow and then start to accumulate at KUIN. The most 
intense snowfall is expected sometime between 15-21z. Winds will 
become northwesterly and gust to 20-25 kts on the back side of the 
system. 


Specifics for kcou: kcou will be on the edge of a winter storm 
system which is affecting the region. Some light snow could 
occasionally mix in with the rain, but rain should be the dominant 
precipitation type until after the cold front moves through on 
late Sunday afternoon, but precipitation will also be winding down 
around the time that it becomes cold enough for snow. Winds will 
become northwesterly and gust to 20-25 kts on the back side of the 
system. Although there is initially some dry air to overcome, 
ceilings should deteriorate to IFR by 06z. 


Specifics for kstl, ksus, kcps: St. Louis Metro area taf sites 
will be on the southern edge of a winter storm system which is 
affecting the region. The dominant precipitation type should 
remain pure rain until colder air arrives with the cold front on 
Sunday afternoon. Winds will become northerly and gust to 20-25 
kts on the back side of the system. Although there is initially 
some dry air to overcome, ceilings should deteriorate to IFR 
overnight.
