.SHORT TERM /THROUGH TONIGHT/...
Issued at 318 AM EDT Wed Jun 3 2026

High pressure at the surface and ridging aloft moving into the Ohio
Valley will be the main drivers for weather today. These features
will keep conditions dry with light easterly winds. Temperatures
will be a bit warmer than yesterday in the upper 70s and low 80s.
Similar to yesterday, ample mixing up to about 750mb will allow for
dry air mix down. Have decreased dew points (and therefore relative
humidity). Minimum relative humidity this afternoon will likely dip
into the mid-upper 20% range.

High pressure centered over the region tonight will bring calm winds
and clear skies. Great conditions for radiational cooling will allow
for lows to dip into the mid-upper 50s.

.LONG TERM /THURSDAY THROUGH TUESDAY/...
Issued at 318 AM EDT Wed Jun 3 2026

Upper level ridging and surface high pressure will persist through
most of Saturday. High pressure will shift just east of the region
and southerly flow will return to the region on Thursday. Southerly
flow will bring better moisture and slightly warmer temperatures.
Expecting temperatures to remain steady in the mid-upper 80s
Thursday through Saturday. Weather will remain dry through this time
period. By Saturday, the western side of the high pressure will see
pressure gradient tightening, which will lead to breezy (gusting up
to 25mph) southwesterly winds for Saturday.

Upper ridging will shift east of the region over the weekend and
multiple shortwaves will move in from the west. On Saturday night
into Sunday, a cold front will push south from southern Canada. This
front will stall over the Ohio/Tennessee Valleys. Ample moisture
over the region will allow for showers and maybe a few storms,
though severe weather is not expected. Over the last several
forecast runs deterministic and ensemble guidance has brought the
stalled front further south into the Tennessee Valley. This will
keep the northern half of the CWA drier early-mid next week. Though
showers will remain over southern Kentucky. QPF remains light with
this event, less than a half of an inch. Otherwise, temperatures
will remain in the mid-upper 80s during this time, though dew points
will be higher, so it will feel muggy.
