.SYNOPSIS...
A cold front will approach the region today and tonight,
dissipating on Tuesday as high pressure builds to the north.
This high will slowly transit to the east, leaving an easterly
flow over the Ohio Valley through Thursday. A low chance of
rain will remain over the area as disjointed mid level energy
transits the region through this time.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Increasing low level southwest flow will lead to developing
weak isentropic lift from west to east across the area through
this afternoon. As we begin to moisten up, this could lead to a
few light rain showers later this afternoon, primarily across
our northwest.

High temperatures will range from near 40 degrees in the north
to the mid 40s across the south.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/...
Exiting s/w energy will bring a chance of rain to the region
tonight and early Tuesday as an upper low in lower MI moves
eastward. The best chance will lie over central OH, beginning a
earliest in west central OH and ending later over southeast OH.

With upper ridging and a dissipating cold front any lingering
rain will disperse on Tuesday. However, cloud cover will hang
tough and some passing sprinkles will remain a possibility.

Tonights lows will drop to the mid 30s and Tuesday will be
slightly cooler in the south with readings ranging from 40-45.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
For Tuesday night into Wednesday, Christmas Day, some weak
embedded mid level disturbances will pass across the Great Lakes
and Ohio Valley region. This will result in mostly cloudy skies
along with a chance of rain. Forcing will be weak, so any rain
would be light. Lows in the 30s will give way to highs in the
40s.

A lull in the precipitation threat is then expected Wednesday
night into Thursday as the mid level disturbances continue to
weaken as they move east. This will then allow a weak mid level
ridge to develop over the region. This period will also mark the
start of a warming trend. After lows mainly in the 30s, highs
will range from the mid 40s north to the lower 50s south.

A couple of more weather systems will affect our area Friday
and into the weekend, with the stronger system arriving on
Sunday. This will result in more chances of rain (higher PoPs)
along with warm temperatures for late December. Lows will warm
into the 40s with highs warming into the 50s.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
A few sprinkles will be possible this afternoon in developing
southwest flow. Cigs will lower into MVFR this evening ahead of
an approaching frontal boundary as more widespread rain showers
develop and shift southeast across the region through tonight.
Some IFR cigs will likely develop late tonight and persist
through much of Tuesday morning, along with some MVFR vsby
restrictions. Cigs will gradually lift back into MVFR Tuesday
afternoon.

OUTLOOK...MVFR/IFR ceilings possible Wednesday and Friday night
into Saturday.
