.DISCUSSION...

Although some sunshine filtered though the high thin clouds today,
it was still a chilly day across the area with temps 5 to 15 degrees
lower than yesterday afternoon`s temps. Despite continued high
clouds overnight and a light north wind, lows will drop to the
upper teens in most areas. Don`t expect a great warmup on Friday
as cold air continues to pour in from the north ahead of an
advancing sfc high pressure sliding through the central U.S. Highs
Friday won`t exceed the 30s. Friday night`s lows might be a tad
lower than tonight`s because winds will drop off as the sfc ridge
settles in over KY and TN. Expect teens for most areas.

Daytime temps will increase a few degrees Saturday but the better
warmup...e.g., 50s...will occur Sunday thanks to brisk southerly
flow on the back side of the departing sfc high pressure center.
Increased moisture and an approaching upper level disturbance will
bring rain chances to the region Sunday through Monday...with the
greatest chances on Sunday night. Rainfall totals should be less
than 1/2 inch.

Forecast confidence decreases by the middle of next week with
significant differences between the more aggressive/colder GFS and
the less aggressive/warmer ECMWF. In general, though, expect
another cold front by Wednesday as a strong sfc high pressure
center moves southeast from the northern Rockies into the Ohio
Valley. This front will help bring another chance of light
precipitation to the area Tuesday night and Wednesday...with temps
low enough to allow for a light rain/snow mix. It will be much
colder behind this system with daytime max temps stuck down in the
30s both Wednesday and Thursday.
