Winter Weather Update

ICE STORM WARNING continues until 6:00pm Tuesday for Bolivar, Sunflower, Washington, Leflore, Grenada, Carroll, Montgomery, Holmes, Humphreys, Sharkey, Issaquena, Webster, and Yazoo counties.

We're experiencing a respite in the rainfall, but expect it to return overnight tonight and continue through tomorrow.  With temperatures hovering at or near freezing, chances remain for freezing rain to resume before morning.  An additional 0.20 to 0.5 inch accumulation are possible in the warning area.

Road conditions in some areas today were dangerous with icing reported on bridges across the Delta.  Power outages were reported in a number of areas.  Over 9" of rainfall have been recorded in Indianola thus far in January.  Trees laden with ice are susceptible to toppling in these saturated grounds.  Rain is expected to continue through Wednesday night into Thursday.

For Wednesday night and early Thursday morning, an upper level low will pass over the area, raising the rainfall chances.  There is a slight chance of snow or a rain/snow mix for the same period.  Uncertainty exists with this system, and updates will be provided as we get closer to that time frame.

Below are two weather statements, the current Hazardous Weather Outlook and the Ice Storm Warning Statement.  Two graphics follow.
