Discussion... 


The winter storm that impacted much of the region the past 24 
hours was coming to an end Sunday afternoon. A few areas of 
freezing rain persisted in far southwest Missouri. A deep closed 
low located over southern Arkansas will migrate slowly to the east 
tonight. Precipitation will continue to wrap around this system 
into southern Missouri into the evening before tapering off 
overnight. Persistent rainfall will continue the risk of localized 
flooding across far southern Missouri. Temperatures will hover 
near freezing over the western Ozark Plateau west of Highway 65. 
This may lead to pockets of freezing rain this evening but 
additional accumulations look to be minor. However temperatures 
will fall to or just below freezing late tonight causing some 
refreezing on secondary roads and bridges. 


Preliminary discussion...Monday through next Sunday...some precipitation may linger 
over the far eastern County warning forecast area early Monday morning...otherwise should 
see clearing from west to east Monday as the cutoff upper low 
continues to shift east. Have generally gone with NAM MOS and 
made some small adjustments to account for snow/melting snow over 
the western County warning forecast area. 


The southern stream of the midlatitude flow will be 
somewhat amplified but progressive through this period. There is decent 
agreement on the timing of upcoming systems that will give US rain 
chances...one on Wednesday night-Thursday night...then another late Sat- 
Sunday. The weekend system looks a bit stronger then the midweek 
system...enough to mention thunder.

Aviation... 


The southwest Missouri airports will begin to experience some 
improving flight conditions over the next 24 hours. A storm system 
that brought rain and snow to the region will continue to exit 
east. 


Lingering rain will persist over the Branson Airport into the early 
morning hours...while a rain shower or two in Springfield can not be 
ruled out. Ceilings at both of these airports will remain IFR to 
MVFR through the morning...while joplins ceiling will improve to VFR 
shortly after midnight.
