Mid-day winter weather update

...UPDATED: 12 March 2009 3:05PM...
Winter Weather Advisory has been cancelled for Shelby, Fayette, and Crittenden Counties. Winter Storm Warning for Tipton County downgraded to Winter Weather Advisory until 10pm.

Previous post issued at 1:00pm:
Not a whole lot has changed as the morning has gone along today. In the Memphis metro area, precipitation has been predominatly rain, with some reports of freezing precip (mainly sleet and snow) in counties north of the city (MWN StormView Radar has it handled well). We got as low as 33 degrees in Bartlett this morning with plain Jane rain. Low-level warm air between 1-3,000 feet has saved us today!

I expect mostly rain to continue this afternoon, with a report of sleet here or there possible in the metro. Precipitation should taper off this evening to drizzle and temps will approach freezing, particularly in northern suburbs, so some freezing drizzle is possible. Another round of precipitation accompanies a low moving out of Texas late tonight. Right now, I think most of that will stay just south of the state line where air is warmer, but the northern fringes of it could skirt Crittenden, Shelby, and Fayette counties after 3am or so. This could result in a chance of mixed precipitation again late tonight. Will evaulate further later today...
