A Winter Weather Advisory is in effect from 9 AM to Midnight Tuesday morning. Snow is expected today that will deteriorate travel conditions this afternoon and evening.
A cold front is located to the west of the region in southeast Missouri this morning. This cold front is associated with a clipper system to the north and should move through the region later today.
The cold front should move through the region around 11 AM or noon. Initially, I expected temperatures to top out above freezing before the front moves through, however that may not be the case. We’ll likely end up just shy of freezing.
Light snow should begin to move into the county after 9 AM. However, snowfall rates accompanying the front could be quite heavy, limiting visibility at times. The snow is expected to continue into the overnight hours as the front slows or stalls over western Kentucky. Below is the simulated radar from the HRRR model.
Because of the slow nature of the front once it gets to western Kentucky, we’ll have to adjust snowfall totals up. I’m currently thinking we’ll see 1-3″ of snow across most of the county. Some areas may pick up a bit more than that. The NWS has also adjusted their forecast to 2-3″. Again, some isolated locations may pick up more than that.
This will lead to worsening travel conditions through the PM hours today. Lows will get down into the single digits, thus travel Tuesday morning may be impacted as well. No melting is expected Tuesday as highs only top out in the mid teens.
That should wrap up this forecast. Thanks for stopping by and I hope you have a great Martin Luther King day!
