Suchan Says: Rain, Snow, Arctic Cold

Steady rain through tonight into some of Sunday morning

Oh we have it all over the next 7 days to be sure!  Rain will be confined to tonight through Sunday morning along with a slight chance very late Monday.  Otherwise the coming forecast is dominated by much colder temperatures and snow chances.

Sunday starts cloudy with areas of rain through the first part of the morning.  Of interest to me, it appears it may turn just cold enough in north central Missouri to support a mix or even change to wet snow.  Places like Bethany, Trenton, Chillicothe to Brookfield may all see some wet snow and perhaps even a light coating on mainly non-road surfaces.

All precipitation steadily moves east and out of the area by early afternoon.  Breaks of sun will gradually build in from west to east through the afternoon giving temperatures a boost into the mid to upper 40s.

Here are some Forecast Track images highlighting Sunday’s forecast.

The first bout of Arctic cold is set to blast in by Wednesday of next week!  The core of this bitter cold pushes over Thursday and will certainly coincide with Thursday Night Football and the Chiefs’ game against Oakland.

850mb temperatures off the GFS around -14C to -16C… December Arctic cold!

Some upper level energy along with a healthy 125+mph jet streak in the upper levels will pass by Wednesday along with the arctic cold frontal boundary.  It appears there is enough moisture to work with to generate flurries and snow showers through the day.  There are computer model discrepancies on how much snow at this stage of the forecast.  But here’s my first call on expectations.

Should new data ahead change, I’ll certainly revise the forecast as necessary.  Of note, it’s a very dry powdery snow that would fall as well.  If we can tap into a decent snow band or two that day, snow to liquid ratios would be quite high, perhaps on the order of 17:1 or even 20:1.
