***FRIDAY MORNING UPDATE***

A busy morning in the 4Warn Storm Center, but I wanted to take a moment to update the blog entry below from yesterday morning.

Intense pockets of snow and sleet have been sliding across the St. Louis metropolitan area this morning.  Please be careful as you hit the roads today.  Not surprisingly, we've had many reports of traffic accidents, most due to the rapidly changing weather conditions.

Look for this mix of sleet and snow to continue around St. Louis through the morning hours, tapering to a light mix or a few light showers toward lunchtime.  We're expecting mainly dry weather for the evening rush hour, with perhaps just a few flurries or spotty drizzle.

Meanwhile, we're still on track for another storm system Saturday, and once again, accumulating snow is possible after the precipitation begins as rain.  Stay tuned to KMOV.com and News4 for updates -- a winter weather advisory could be posted later today for the chance of accumulating snow from late Saturday afternoon into early Sunday.

Below is my original blog post from yesterday.

-----------------------------------------

As I sit down to write this blog entry (about 9:30 AM on Thursday, March 21), the temperature at Lambert International Airport has dropped 42 degrees since yesterday's high of 75!  It is now 33 degrees and, just to add insult to injury, Lambert is also reporting flurries.  Hmmm, so much for our taste of Spring.

As a stark reminder of the fact that we're only in the early throws of Springtime, the 4Warn Storm Team is now analyzing the possibility of accumulating snow in our area from Friday into early Sunday.  Yep -- snow!  We're tracking two storm systems to our west, both of which look to bring scattered rain showers to parts of eastern Missouri and western Illinois, and either of which could bring some minor accumulations of snow as well.  The first is pulling out of southern California and will impact us Friday, while the second is still gaining strength off the northern California coast and will bring another chance of rain and/or snow Saturday into very early Sunday.

The image you see above is Friday's snowfall accumulation projection from the local National Weather Service Forecast Office as of the time of this blog entry.  To see the very latest forecast map, check the "Winter Graphics" section on the local National Weather Service website.

With both storm systems, we're expecting the best chance of snow or rain/snow mix north of Interstate 70 (hence the higher accumulation totals to the north on the map above), with mainly rain elsewhere.  That being said, there is still enough uncertainty surrounding these storms that residents in and around the St. Louis metropolitan area should stay tuned for updates to the forecast.  Stick with KMOV.com and News4 for the very latest.  If you have a smartphone, you can download the free KMOV app to stay up to date with the latest forecast information and radar images on the go.
