A cold front will finally shift through southern Missouri on Tuesday, providing a sharp temperature gradient from northwest to southeast. The eastern Ozarks could reach the 50's on Tuesday, while west central Missouri may be capped off in the 30's. Hey! It is winter you know!
There is also a signal for some drizzle or maybe some light rain that occurs with this frontal passage. Any precipitation that falls will remain very light.
Wednesday through Thursday will be unseasonably cold as a Canadian air mass continues to deepen across the Ozarks. Wednesday's high temperatures will only warm into the 20s and lower 30s. Wednesday will be dry, however, late Wednesday night into Thursday, some light snow is not out of the question.
The models have been struggling to adopt a solution for Thursday's snow chances. The ECMWF has been the most stable solution, and suggests that some light snow will spread across the region, and taper off by Thursday night. We won't discuss what the GFS is showing since it's been extremely erratic with it's solutions for Thursday. With the inconsistency in solutions, we have maintained a slight chance for snow accumulations. Confidence in snow accumulations remains very low at this time.
An upper level shortwave will track southeast and into the central and southern Plains late Thursday with snow spreading across Oklahoma and Arkansas. We are expecting most of this activity to remain south of Missouri tonight and no additional snow accumulations are forecast for our area. The main weather story for our area will be the cold temperatures and wind chills. High pressure will continue to build into the area at the surface and with the snow pack in place, we are expecting temperatures to dip into the single digits to around 12 degrees across far southern Missouri. Wind chills will dip into the single digits below zero for a good portion of the area. High temperatures on Friday will only warm into the teens to low 20s once again. www.taneyservices.com
