Area forecast discussion 
National Weather Service Springfield MO 
707 PM CDT Sat Mar 20 2010 


Discussion... 


Its been a wild 48 hours over extreme southeast Kansas and the 
Missouri Ozarks. Its been just as wild here at the National Weather 
Service. After experiencing upper 60 and lower 70 degree 
temperatures Friday afternoon...less than 24 hours later we're 
dealing with heavy snow. 


First and foremost...we upgraded 
Polk...Dade...Hickory...Dallas...Camden...and Morgan counties to a 
Winter Storm Warning. Snow accumulation roughly along a line from 
Lamar...to Stockton Lake...and up to Cross Timbers has been quite 
impressive. Several observers within this geographic zone has 
measured anywhere from four to six inches...all occuring within the 
last couple of hours. Therefore the upgrade to a warning was 
needed. Storm total accumulations within this area could range from 
6 to 9 inches. 


Further west into southeast Kansas and the Highway 71 corridor of 
western Missouri...measurements have ranged from 2 inches in Newton 
and McDonald counties...up to around four to six inches from 
Columbus/Joplin up to Nevada and Fort Scott. An additional one to 
three inches can be expected within this zone. 


Further east in areas extending from Table Rock...to 
Springfield...Lebanon...up to Tuscumbia...light snow is 
expected...however the warm ground temperatures are melting most of 
it so far. Therefore the advisory remains in effect for these 
areas...with accumulations expected to range from a trace up to two 
inches. Areas of western Greene County could accumulate more with 
the cooler temperatures in this region. 


I'm also growing concerns about flooding...and will likely be 
issuing some warnings here soon...especially within the Highway 65 
corridor where heavier precipitation amounts have occurred.

Aviation... 


Pilots flying in and out of the southwest Missouri airports will 
experience IFR and MVFR conditions over the next 24 horus. A 
vigorous storm system has invaded the region...causing a large 
shield of rain and snow. Low ceilings within the IFR 
category...along with several obstructions to visibilities have 
resulted and will continue. Visibilities will be lowerd by 
fog...rain...snow...and sleet at times. 


Look for gusty north winds to persist...and maybe even strengthen 
overnight as this storm system continues to gain strength. 


Flight conditions may improve overnight Sunday into Monday morning 
as the precipitation and low clouds exits east of the region.
