To Dream or Not to Dream of a “White Christmas?”

Good Saturday bloggers,

Well, here we are on the doorstep of Christmas and it looks like we will not have to dream of a “White Christmas!” A series of disturbances will be tracking out of the Rockies, consolidating to one main disturbance as they move east across our region. Based on the current track of the system it looks like the KC area will be on the southern edge of the accumulating snow. In order for there to be a legitimate “White Christmas” we are going to need at least 1/2″ of snow as anything less could sublime before Christmas day. Sublime means the snow evaporates going from the solid to gas state.

Let’s go through the time line and then the latest forecast for amounts.

SATURDAY AFTERNOON: It will be dry with increasing clouds as highs climb to the upper 20s and low 30s.

1

6 PM TO MIDNIGHT TONIGHT: It will be a dry, cloudy and cold evening in KC with snow increasing across Nebraska, Iowa and far northern Missouri. Temperatures will be in the mid to upper 20s.

2

MIDNIGHT TO 3 AM SUNDAY: The snow will be increasing from northwest to southeast and moving into KC. Temperatures will be in the low to mid 20s, so any snow will stick to all surfaces.

3

3 AM TO 6 AM SUNDAY: This is the most likely time frame for the most snow to occur in the KC area. There will be heavier snow showers embedded in light to moderate snow. Temperatures will stay in the low to mid 20s with a 10-15 mph north wind, so wind chills will be in the single digits.

4

6 AM TO 9 AM SUNDAY: The snow will be shifting east and likely ending in KC by 9-10 AM. Temperatures will be in the low 20s with wind chill values near zero as north winds blow at 10-20 mph.

5

6 AM TO 9 AM SUNDAY: This data has the snow over by 8 AM as the system races east and cold air pours south.

6

9 AM TO NOON SUNDAY: The snow will be over and the sky will be clearing from west to east with temperatures in the teens and low 20s. So, if you are headed out to Arrowhead it is going to be very cold with wind chill values around zero in the morning and single digits in the afternoon. Sunday afternoon will be mostly sunny with highs 25°-30°.

How much snow will occur on your yard or farm?

SNOWFALL FORECAST KC (NORTH I-70): As is, we are expecting slightly over an inch north of I-70.

8

SNOWFALL FORECAST KC (SOUTH I-70): At this time it looks like slightly under and inch. What does this mean for the Snowflake Contest? Well, it has to snow 1″, as measured by one of our 41 Action News meteorologists, at our studio on the Plaza. So, if this verifies, we may come up short.  It is going to be a close call.

9

SNOWFALL FORECAST REGION: It still looks like a band of 2″ to 3″ of snow will occur along the Missouri-Iowa border with 1″ to 2″ between that band and I-70. A dusting to 1″ is possible south of I-70. This can still shift south or north by 50 miles, so it is not quite set in stone. But, it looks like a “White Christmas” is likely for most locations in our viewing area.

Merry Christmas! Please don’t drink and drive.
