Late winter storm update–less snow, severe ice storm

Sleet and ice accumulations have reached one inch at my location.  Freezing rain has been falling and is weighing down trees and wires.  Another .25 to .6 of ice could accumulate overnight.  If this verifies, tree and power line damage is likely.  A later change-over to snow may result in less snowfall in the last phase of the storm, perhaps only 1 to 3 inches, bringing the storm total to 6 to 9 inches.

This is a very serious situation.  Be prepared for possible power outages and near impossible travel as this storm evolves.

Major Winter Storm Update

Heavy sleet mixed with freezing rain continues in the Cincinnati metro area.  While icing on trees and wires is minimal so far in western Cincinnati, heavy sleet is building up.  Piles of sleet are accumulating around houses where roof troughs are funneling the sleet onto the ground.  Do not be surprised to find deep piles of sleet in the morning.

Heavy snow appears likely for morning rush hour.  The storm will not wrap up until midday Wednesday.  Heavy precipitation will continue through the night.  A crippling ice storm is ongoing in parts of Kentucky and will likely be spreading into northeast Kentucky.  This storm is beginning to resemble the crippling Christmas storm of a few years ago.  Expect storm total snowfall in Cincinnati of 8 to 12 inches.

Remember that 1 inch of sleet has the same mass as 10 inches of snow and will be very heavy to move, as well as very difficult to clear from roadways.

Major Winter Storm Update–A lull, then the worst is yet to come

A major winter storm is under way with the predicted 3 to 5 inches on the ground this morning and snow still falling.  This is only the beginning of what could be an historic storm in parts of the tri-state.
 
Snow will ease today and may even taper off for a time.  However, a deepening storm system will cause moisture to surge back later today.  This surge of warmer, moist air may cause a crippling freezing rain storm to our south with mixed precipitation making it into the metro area, but not any farther.  It is still not certain where the changeover line will set up but it appears it will be near the I-71 corridor.  Areas which switch over will have storm totals held down some.  Areas which don’t change over but are close will see the heaviest snow.
 
As the night goes on, mixed precipitation will change back to snow and a band of heavy snow will move through.  Snow now appears as if it will continue well into Wednesday, although at a lighter rate.
 
Storm totals will be 6 to 11 inches with locally higher amounts possible.  This will be a long duration, multi-part storm which will have a major affect on the local area.
