Due to mid-level ridging that has moved in from the west, temperatures will be in the mid to high 50s this afternoon, which is very warm for this time of year.
As of late tonight, a shortwave trough and associated surface low are moving south out of Canada and into the Dakotas.
The precipitation is expected to cross the border from Iowa into Missouri late tomorrow morning and steadily move farther south during the afternoon and overnight hours, according to forecasts.
When it comes to sites along and south of US Highway 36, precipitation should start as rain, with a gradual change to snow as the temperature profiles dropdown.
Snow is expected to begin falling in the Kansas City metro area about midnight tomorrow night, with the highest accumulations expected between 2 a.m. and midday Saturday.
Snow is expected to finish from north to south late Saturday morning into early Saturday afternoon, according to the National Weather Service.
Compared to the overnight prediction package, snowfall totals have not altered much, but totals have risen a little farther south into central Missouri, prompting the extension of the Winter Storm Watch into these regions.
For areas of northern and north-central Missouri, snow accumulations of 4 to 7 inches are expected this week. For the Kansas City metro area, 2 to 4 inches of snow is expected, with smaller amounts expected in the southern and southern-most parts of the metro area.
It seems that certain models have been pushing greater snowfall totals a little farther west, so we'll have to wait and see whether this pattern continues.
Snow accumulation predictions will continue to be adjusted during the following 24 hours, according to forecasters.
Wind Gusts on Saturday and Sunday
Additionally, wind gusts of up to 30 mph on Saturday morning may cause blowing snow and restrict visibility to a mile or less at times, in addition to the snow.
On Saturday morning and afternoon, wind chills will be as low as slightly below zero and as high as the teens, depending on the location.
Warmer Temperatures Next Week
Warming trends begin Monday and continue into Tuesday, with high temperatures in the 40s to low 50s for most sites by Tuesday afternoon. Sunday will be cold, with highs in the 20s to low 30s.
On Tuesday night, a cold front should pass over the area, bringing significantly lower temperatures back to the region for Wednesday. During this period, it is likely to be rather dry.
