...Updated Aviation Discussion...

.Short Term...(This evening through Friday night)
Issued at 252 PM EST Thu Jan 18 2018

High pressure to our south and a dry atmosphere will keep our skies
clear tonight and Friday. Lows tonight will still manage to drop
down into the teens over the snow cover, but tomorrow we should be
able to rebound to the lower 40s on SSW breezes.

Low clouds swelling from the western Gulf into south Texas today
will eventually make it into central Kentucky and far southern
Indiana Friday night as the high to our south budges a bit to the
east. Lows will mostly be in the 20s.

.Long Term...(Saturday through Thursday)
Issued at 304 PM EST Thu Jan 18 2018

Low pressure spinning up in the lee of the Rockies Saturday evening
ahead of a deepening upper trough over the Intermountain West will
head northeast to the Great Lakes, swinging a cold front through the
Ohio Valley Monday afternoon/evening. A few showers will be possible
in the warm sector out ahead of this system Saturday night and
Sunday, but by far the main chance of rain will come with the front
on Monday. It will be a dynamic system with gusty winds Monday
afternoon, but with low instability expect only an isolated rumble
of thunder at best.

Rainfall totals for the weekend through Monday are anticipated to
only be around half an inch, so flooding is not expected at this
time.

Went a bit windier and warmer than guidance on Monday ahead of the
cold front and with the snow pack gone, with highs right now progged
near 60. Southwesterly wind gusts to 30 mph not out of the question.

We`ll then return to dry weather and seasonable temperatures for
Tuesday through Thursday as high pressure builds in.

expected for tomorrow.
