.Short Term...(Today and tonight)
Issued at 310 AM EST Thu Mar 4 2021

A cold front, stretching from west to east, is working its way south
through Kentucky. With a dry atmosphere and upper ridging in place,
skies over the region will remain clear and dry. Northerly winds
behind the front will help to keep highs cooler than yesterday`s for
most. Some areas in southern Indiana will stay near 10 degrees
cooler today with temperatures in the low 50s, but the gap between
yesterday`s highs and today`s will lessen to the south. Some areas
near the Tennessee border could make it a couple of degrees warmer
than yesterday with temperatures in the low 60s.

Tonight, winds remain light and veer slightly to the northeast.
Clear skies will result in brisk low temperatures Friday morning.
Areas across southeast Indiana and the Kentucky Bluegrass are
expected to see the mid to upper 20s. Slightly warmer temperatures,
near freezing, should be observed near Bowling Green.

...Chilly This Weekend, Warmer Next Week...

A deep upper level trough will be anchored over eastern Canada and
the Northeast US Friday, with upper ridging over the Rockies. Friday-
Friday night, a southern stream initially over Oklahoma opens up as
its forced southeast toward the Gulf Coast. This pattern will keep
low-level thicknesses suppressed with NW flow aloft and northerly
low-level flow as well. Expecting the southern stream system to only
spread SCT-BKN cirrus across the area Friday. Highs will be in the
mid 40s to lower 50s.

A northerly mid/upper level jet helps carve out a deeper trough over
the Great Lakes and Ohio Valley over the weekend. Sfc high pressure
sinks southeast toward the region during this time. Expect fair
weather to continue with temps a bit below normal. Lows will dip
into the 20s both Saturday and Sunday. Highs Saturday will again
reach the mid 40s to around 50. 50-55 degree highs will be more
common by Sunday with ridging nosing in from the west.

Upper ridging does into to build over the eastern US early next week
as sfc high pressure shifts to the East Coast. High temperatures
begin to push above normal by Monday with mid 50s to lower 60s
expected. Temps warm well into the 60s Tuesday. 65-70 F may be
common Wednesday due to strengthening southerly flow ahead of a cold
front. Shower and thunderstorm chances return to the forecast by
late Wednesday into Thursday.
