Rain & Snow for the Plains

A fairly potent storm system is working its' way onto the central plains and will bring significant chances of rain and even snow to areas.  The large trough that will work onto the plains will become cutoff at 500hPa and thus begin to wander the area for a few days until mid-level flow is able to push it off into the Ohio Valley.  While on the plains this system will be able to use all of the moisture available to produce ample amounts of precipitation.  The heaviest precip amounts through Monday morning should be confined to the areas along the cold front passage in the Mississippi Valley regions.  After which the deformation zone along the low pressure system should begin to produce the highest amounts of precipitation.  Interestingly enough, this system does become cold enough to support frozen precipitation over areas of Kansas, Missouri, Nebraska and Iowa on Monday and Tuesday. 

The potential for snowfall and sleet has prompted some Winter Weather Advisories for portions of KS/NE/MO with 3-6 inches of snow being possible across parts of the region.  Other areas may see at least a dusting of snow, and some slick conditions throughout the day on Monday.  You can see a graphical representation of the thoughts from the Kansas City NWS below:




I am currently in Kansas City, MO where I am completing a job interview and some operational forecast testing, thus this event will be very interesting to forecast as I try to show off my forecasting skills.  Nothing like a good cutoff low, mixed precipitation type storm to test on!
