INDIANAPOLIS - A significant winter storm is expected to bear down on central Indiana beginning late in the evening on Christmas and through the day on Wednesday.
The National Weather Service has issued a winter storm watch from Tuesday evening through Wednesday evening. It is likely the watch will be upgraded to a warning once the track of the storm system becomes clearer.
A low-pressure system will develop over Texas and will track into the Tennessee Valley and Ohio Valley, bringing a nasty mixture of snow, sleet and freezing rain to the region.
The winter storm watch includes all of central Indiana.
Snowfall accumulations of 5 to 9 inches are forecast in the Indianapolis area, but the totals could be skewed by how much of the wintry mix falls. Snowfall totals are expected to be slightly lower south of Indianapolis, where more of the wintry mix could fall.
The wintry mix is expected to move into the area after 10 p.m. on Christmas. There is still some uncertainty in the forecast.
A low-pressure track more to the west will result in less snow because more warm air would work into the area, while a forecast track farther east could result in higher snow totals.
Along with the wintry mix, winds are expected to gust to up to 40 mph, causing blowing and drifting snow.
