The evening data from the upper air balloons show two differences from earlier today:
- There is more Gulf of Mexico moisture than originally anticipated.
- The low pressure system in the upper atmosphere is going to be a bit stronger than I originally thought.
This translates into more snow near and east of Interstate 35 between Wichita and Perry (OK) than I first thought. This seems like a reasonable initial estimate given these new conditions.
Bottom line: In Kansas south of U.S. 400 and in Oklahoma north of I-35, three inches or more of snow seem quite possible. Some spots, especially between about Woodward and Garden City, could see as much as 8 inches. No strong winds are forecast.
Also, note there could be spots of heavy snow (≥ 3″) in parts of the Ozarks region.
