Even though the spring season has just begun...a snow storm will affect the region by Thursday as colder than normal temperatures remain entrenched over the area. Will see precipitation develop north of a warm front across southern Missouri by midday on Thursday. The best chances of snow will be Thursday night...before tapering off by Friday morning. As for precipitation type...at this time it looks to be all snow in our area...while further to the southwest near Springfield a mix of rain and snow is possible at times. There will be a very sharp cutoff from snow to no snow accumulation with this storm. At this time the best chances for accumulating snows will be along and southwest of a Jefferson City to Farmington line. Three to 5 inches of snow is possible over the eastern Ozarks with higher amounts further to the west over southwestern Missouri. However...some uncertainty exists on the track and development of this winter storm...so check back frequently for upda! tes.   (Please visit http://weather.gov/lsx for more information.)
