... Wintry weather expected for the latter half of the week and next
An expansive storm system will spread from the Southern
Plains through the Ohio Valley and into New England late this
week. Across the Ohio Valley... an Arctic cold front will slide
through Thursday evening with cold air gradually working in behind
it Thursday night through Friday night. However... a layer of warm
air aloft will remain in place just above the lower-level cold
air. This will bring precipitation types into question early
Friday through Friday night.
Current data suggests rain will begin transitioning to a mix of
wintry precipitation across portions of southern Indiana as early
as midnight Thursday night. By daybreak Friday... this transition
line of rain to a wintry mix is expected to be stretched along the
Ohio River... and then move south of the river through the day
By Friday evening... cold air at all levels will overspread most of
the area... changing much of the precipitation over to light snow
as the event ends Friday night. The Lake Cumberland region will
likely experience a wintry mix as the event comes to an end.
The overall precipitation type evolution and exact timing are not
yet fully known at this time. However... confidence of an
impactful wintry weather scenario including accumulations of
snow... sleet... and possibly some light freezing rain is moderate
north of the Ohio River... and low along and just south of the
river. Stay up to date with the latest forecasts as details become
Another weather system will impact south-central Indiana and
central Kentucky late Saturday night and Sunday. Cold air will be
in place at the surface early Sunday which should result in a
period of freezing rain... especially over southern Indiana as well
as north-central and east-central Kentucky where a coating of ice
is possible. Over south-central Kentucky... any freezing rain early
Sunday morning will change to rain during the day.
The focus on wintry weather potential should not take away from
the fact that a heavy rainfall event from Thursday through Friday
night and again on Sunday could lead to some flooding concerns.
This is especially true across south-central Kentucky where 2 to 4
inches of rain are expected throughout the event. If you live in
low lying or flood prone areas... watch water levels closely if
heavy rains persist and take necessary precautions.
