.WHAT HAS CHANGED...
A Heat Advisory has been issued for the Ohio counties as heat
indices will reach above 100 degrees starting Monday.

1) Hot and humid conditions are expected across the region this week.

2) Low chances for showers and thunderstorms today and tomorrow,
then again on Friday as the surface high pressure breaks down.

.DISCUSSION...
KEY MESSAGE 1...
High pressure will begin to build to the southeast as upper level
ridging moves into the eastern half of CONUS. Concurrently, a low
pressure system will move north across the Great Plains dragging a
warm front through the region during the day tomorrow. This will
bring much warmer and humid air in from the west-southwest and
temperatures will begin to rise well above average starting
tomorrow. The warm front will only clear the western counties in
Ohio by tomorrow evening, and heat indices will rise as a result and
exceed 100 degrees. A Heat Advisory has been issued for the I-75
corridor starting noon tomorrow. Hot and humid conditions will
spread to the remainder of the area as the warm front pushes north
Monday evening. An additional Heat Advisory has been issued for the
rest of Northern Ohio starting at noon on Tuesday to account for
this increased temperatures and heat indices. Both Heat Advisories
will run through Thursday evening, though hot and humid conditions
may last into the weekend with lower confidence. Heat indices will
be the highest Wednesday and Thursday as they approach 105, with
areas out west potentially eclipsing that mark. An upgrade to an
Extreme Heat Warning may be needed for at least the I-75 corridor
during that time period. To go along with the daytime heat,
overnight lows will be warm as well. Temperatures will only drop
down into the mid to upper 70s this week, providing little relief to
to the heat. As mentioned above, confidence in heat related
headlines decreases with the high pressure breaking down into the
weekend.

KEY MESSAGE 2...
Showers and thunderstorms are possible this afternoon along a
stationary boundary that is located across the Ohio Valley. The best
chance for any showers would be in eastern Ohio as the drift
northward. Additionally, showers and possible in Northeastern Ohio
and Northwestern Pennsylvania as well with interaction with the lake
breeze. The boundary will move to the south this evening and
precipitation chances will decrease. Tomorrow, as the warm front
pushes north, there is a low chance for showers and thunderstorms
across Northeastern Ohio and Northwestern Pennsylvania in the late
evening to early morning on Tuesday.

Late in the week the upper level ridge will begin to break down and
the surface high will weaken. A few long range models depict a
shortwave moving through the region on Friday that could bring
showers and thunderstorms back to the area. Will need to monitor how
this unfolds throughout the week as there could be potential for
organized thunderstorms.

.AVIATION /18Z Sunday THROUGH Friday/...
Widespread VFR conditions will diminish for many terminals
tonight to MVFR and possible IFR and clearing skies, low level
moisture, and weak winds result in patchy fog developing. Most
terminals will reach these diminished conditions gradually
beginning at 06Z Monday and peaking near 10Z. The only
terminals likely not impacted by these diminished conditions
will be KERI and KTOL, although confidence in diminish
visibilities at KFDY remains low so opted to use TEMPO for 4SM
but will have to monitor fog development. Any diminished
visibilities should improve after sunrise tomorrow, eventually
all returning to VFR by mid to late morning. Winds overnight
will be light and variable before become sustained from the
southwest at 5-10 knots. A lake breeze is expected to develop
and possibly impact KCLE and KERI Monday afternoon.

Outlook...Mainly VFR conditions expected to persist as high
pressure influences the area.

&&

.MARINE...
High pressure will persist over the area into Monday before a
warm front begins to lift north across the basin. Light
northeast winds this evening will gradually veer to become
south-southwesterly at 5-10 knots Monday night. Once the warm
front fully lifts north, high pressure will build over the
eastern US and persist into at least Friday. Southwest winds of
5-10 knots will be maintained through that period.

&&
