&&

.KEY MESSAGES...

northern Ohio with patchy fog likely elsewhere across the area.

2) High pressure builds into the region and dry weather and
warming temperatures are expected through the majority of the
week with a low chance of showers on Wednesday.

.DISCUSSION...
KEY MESSAGE 1...
Dense fog as begun to develop across central and northern Ohio
early this morning and will persist through around 9AM.
Visibilities are seen dropping down to a quarter mile or less in
places with dense fog creating hazardous driving conditions.
Elsewhere throughout the area, fog has been less widespread
though there are areas of patchy, dense fog. May need an
expansion of the Dense Fog Advisory in the coming hours if those
locations begin to become more widespread. Fog should dissipate
this morning as temperatures begin to rise.

KEY MESSAGE 2...
An upper level ridge begins to build into region starting on
Monday and will persist through the middle of the week. Dry
weather is expected and temperatures will rise into the upper
70s to low 80s by Wednesday afternoon. On Wednesday, a weak
trough is expected to move through the region that may provide
enough support for showers and thunderstorms throughout the day.
Currently PoPs are fairly low, with the highest chance south of
the US 30 corridor with a isolated thunderstorm to the north
possible as well.

Behind the trough, a surface cold front will drift south-
southwestward across the region and temperatures will drop down
near seasonally average, with highs in the mid to low 70s, for
the second half of the week. High pressure will build into the
region from the north on Thursday bringing dry weather to end
the week. Global models show an upper level trough developing
over eastern Canada and moving south this weekend. Currently
precipitation chances are low, but a cooler air mass moving into
the region is possible. Though, there is plenty of spread among
models in regards to high temperatures, so confidence is low on
how cool it will be.

.AVIATION /12Z Monday THROUGH Friday/...
The main aviation weather concern will be regarding low ceilings
and areas of dense fog with low visibilities early this
morning. Conditions are starting off impactful for aviation with
LIFR/IFR ceilings and visibilities this morning. Flight
categories will improve quickly later morning. Mainly VFR
conditions are expected by the afternoon through the late
evening. There is the potential for areas of low stratus
ceilings and fog with IFR conditions to redevelop after 06z
tonight. Winds will be rather light and variable at times. A
general northeasterly flow of 5 to 8 knots will develop later
today into this evening.

Outlook...Non-VFR possible with rain showers in central Ohio on
Wednesday.

&&

.MARINE...
Overall beautiful and quiet marine conditions are expected to
continue for Memorial Day and linger much of this week. High
pressure will build in across the region. Winds will be light
and variable under 10 knots and waves of 1 foot or less are
expected to persist through mid- week.
