AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
125 AM EDT Sat Jun 15 2024

.SYNOPSIS...
High pressure entering the Ohio Valley will result in mostly
sunny skies and increasing temperatures. Starting Monday and
lasting through Friday, high temperatures are expected to reach
the middle and upper 90s. Overnight lows from 70 to 75 will
compound any heat related issues that the region faces for the
coming work week.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
-- Changed Discussion --
Cold front has pushed south of the Ohio River and will continue
out of the forecast area overnight. A band of post-frontal mid
clouds lingers but should dissipate over the next few hours.
Given temperature trends, bumped up lows just a bit.

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/...
The ridge/high pressure continue to dominate the forecast on
Saturday, keeping the region dry and mostly sunny. Daytime high
temperatures rise to the mid 80s, with dew points falling to the
50s, resulting in a slight relief from the heat. The high
continues to move east through the Ohio Valley into the evening
hours and southerly flow will return during the late overnight
hours. This starts the return of moisture and heat into the
region and will be the onset of some very warm/sticky
conditions.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
The main concern in the extended period, Sunday through Friday, will
be the expected prolonged heat wave that we have been discussing
over the last several days.

A mid level ridge will begin to build northward into the middle Ohio
Valley on Sunday. Low level flow will also become southerly. Thus,
dewpoints will begin to creep upward as well as air temperatures.
Highs will range from the upper 80s to the lower 90s. Some heat
indices may reach near 95 along and south of the Ohio River.

For the upcoming period, Monday through Friday, the mid level ridge
will continue to build across the Ohio Valley, mid Atlantic, and
parts of New England. There are some hints that a weak s/wv may ride
on the western periphery of the ridge during the Monday/Tuesday
time frame. This may bring a low chance of a shower/storm and
perhaps a little more clouds. Otherwise, the mid and latter parts of
the week will feature hot temperatures with dewpoints in the
mid/upper 60s. This will result in heat indices in the 100 to 105
degree range. Highs will generally be in the mid and upper 90s, with
a chance of 100 degrees being reached at some locations. Little
relief will be felt at night with lows generally in the lower to mid
70s. Will continue to highlight the heat and humidity in the HWO.
Will also watch if records may be tied or broken (Max Temps, High
Minimum Temps). And with the diurnal instability, an isolated
afternoon/evening shower/storm (10-15 percent) can not be ruled
out.

&&

.AVIATION /05Z SATURDAY THROUGH WEDNESDAY/...
-- Changed Discussion --
VFR will prevail through the period. Some lingering mid clouds
will dissipate early in the period. Later there will be some
thin cirrus. Winds will be northeast to east 10 kt or less.

OUTLOOK...No significant weather is expected.
