126 PM EST Wednesday, February 22, 2017
A low pressure system south of the Ohio Valley will continue to move east,
resulting in light rain showers gradually exiting the basin to the east.
Another low pressure system will exit the Rocky Mountains and move into the
central plains tonight and Thursday. Ahead of this low, a warm front will
develop over the northern Ohio Valley, becoming a focus for light rainfall to
develop. As the low approaches the Ohio Valley on Friday, the warm front will
lift into the Great Lakes. Friday night a cold front associated with the low
will reach the western Ohio Valley. Strong storms are expected to develop ahead
of and along the cold front. The front will move through the basin Friday night
and exit to the east early Saturday. The front will push the unseasonably warm
temperatures out of the basin with more seasonable conditions returning.
A disturbance is forecast to move through the basin on Monday providing some
modest amounts of rainfall. Another more significant low pressure system is
expected to develop and move through the basin around mid-next week.
