.KEY MESSAGES...

* A few pockets of light rain will be possible (<20% chance) tonight
  into Monday morning, with most places remaining dry. Patchy fog
  will be possible across the area tonight.

* Strong upper ridge over the region will result in the hottest
  temperatures of the summer for all of next week. Highs in the low-
  to-mid 90s, dew points in the mid/upper 70s will result in heat
  index values above 100 to near and even above 105. A Heat Advisory
  is out across the entire area Monday through Thursday.

* High heat and humidity will continue into the Independence Day
  Holiday with the potential for isolated to scattered thunderstorm
  during the afternoon and evening.

.SHORT TERM /THROUGH TONIGHT/...
Issued at 417 PM EDT Sun Jun 28 2026

The last portion of our heavy showers and storms that produced
considerable-to-significant flash flooding across the area has
finally departed to the southeast. A weak frontal boundary just off
to our north will become NW to SE oriented through this evening and
the overnight. A few areas of very light rain could occur
through the morning hours, but with the departure of the forcing
mechanisms that aided all of the recent rainfall, little-to-no
appreciable precipitation is expected. The latest HREF guidance only
gives up to a 30% chance for rainfall greater than 0.10", and that
is mainly confined to areas along and east of I-75.

For tonight, mid and upper-level ridging will begin to build in
over the region and will be a key feature to pay attention to not
only in the near-term, but also in the extended forecast period.
Cloud cover across the area will slowly break up, with mostly clear
skies expected during the late overnight hours. With all of the
moisture in place from the recent rainfall, in addition to calm
winds forecast tonight, patchy fog could develop across the region,
with areas of fog possible in the eastern portions of the CWA.
Temperatures will not fall much tonight, with morning temperatures
in the low-to-mid 70s expected.

.LONG TERM /MONDAY THROUGH SUNDAY/...
Issued at 417 PM EDT Sun Jun 28 2026

To close off the month of June and start the month of July, we will
be in a prolonged stretch of hot temperatures and oppressive
humidity. A robust 594-597 dm mid/upper-level ridge builds over the
eastern CONUS, which will be responsible for keeping us dry once a
weak surface frontal boundary lifts off to the north on Monday.
Additionally, the ridge will also be allow temperatures to climb
up into the low 90s to start the week, with highs in the mid 90s
possible by the middle and latter parts of the workweek. In the
latest LREF guidance, probabilities to exceed 90 on Monday are
greater than 70% west of I-65, and range from 40-70% to the east.
Probabilities increase across the area Tuesday and Wednesday, with a
greater than 75% chance. Probabilities for temperatures above 95 are
low (<35%) until Wednesday, with widespread 40-60% chances being
outlined Wednesday through Friday. One of the factors in place to
limit our maximum temperatures, especially earlier on in the week,
is the remaining moisture from our recent rainfall. As that water
gets evaporated into the atmosphere, the energy needed to allow this
evaporative process cools near-surface temperatures as the moisture
coverts to water vapor.

While we are not as concerned about the possibility of record-
breaking heat across the region, the thing that gives us the most
worry will be the higher dew points that will last throughout
the week. In combination with all of the rainfall we`ve had
recently, dew points in the mid 70s will result in oppressive
humidity across southern Indiana and central Kentucky, as well as
our highest heat indices of the year. A Heat Advisory has been
issued across the entire CWA beginning Monday at 12 PM EDT, lasting
through Thursday evening. Heat indices above 105 will be likely this
week, with a currently low (<15%) chance for indices meeting or
exceeding Excessive Heat Warning criteria (110) later this week.
Make sure to take precautions if you are outside for considerable
amounts of time this week as this period of hot and humid weather
persists.

By the end of the week and going into the 4th of July weekend, the
upper-level ridge begins to slowly break down and shift off to the
east. A few shortwaves will move over the western periphery of the
ridge that could move over the region if the ridge moves far enough
east. This would set up our next chance for showers and storms to
develop, but disagreement in deterministic and ensemble guidance has
kept probabilities of precipitation below 35%.

.AVIATION /00Z TAFS THROUGH 06Z TUESDAY/...
Issued at 726 PM EDT Sun Jun 28 2026

VFR conditions with few mid to high level clouds will continue this
evening across the area. Overnight, a mixture of calm winds and
moisture from recent rainfall could produce areas of patchy fog.
Additionally, a signal for lower stratus is also possible in the
early morning hours. LEX and RGA could see cigs close to MVFR
briefly before lifting by tomorrow afternoon. Otherwise, winds will
be light and variable overnight with predominantly SW flow tomorrow.
