area forecast discussion
national weather service cleveland oh
648 pm edt Thu jun 22 2017

Synopsis
A warm front will lift across lake erie this evening.

Low pressure over the western lakes will move northeast into
canada by Friday, bringing a cold front east across the region.

A broad trough of low pressure will then remain over the area
through the weekend. High pressure at the surface will begin to
move in from the west Monday night into Tuesday.

Near term through Friday night
Broken line of convection that developed across NW oh has moved
north of the forecast area. Think for the rest of the evening
will be hit or miss with the heavier rain moving into the area
after midnight. So will continue with chance pops this evening.

Original discussion...

warm front located from southern michigan to NW pa. This
boundary should continue to lift northward through the evening
and be north of lake erie around midnight. The better shear and
instability was located across NW pa. If any storms get stronger
it will be across this area through early evening. Cant rule
out an isolated thunderstorm elsewhere in the warm sector.

Confidence in any thunderstorm development is low.

We will then watch the moisture advection increase ahead of low
pressure that will move into the central great lakes. There will
be tropical moisture into the area but the main focus appears to
be south of the county warning area until the cold front arrive
Friday afternoon into the evening. Locally heavy rainfall will
be possible but mainly across the eastern half of the area.

Drier air moves back into the region Friday night with
showers thunderstorms ending from west to east.

Warm tonight with the increased moisture. Lows will likely be
within a couple degrees of 70 at most locations. Humid on Friday
but with rain and cloud cover highs will be in the mid 70s to
lower 80s. Cooler Friday night in the wake of the cold front.

Lows should dip back into the 50s away from the lake.

Short term Saturday through Sunday night
A surface cold front will move east with waves of low pressure
expected along the frontal boundary Friday night allowing ridge of
high pressure to build into the local area for Saturday. The ridging
will be dominant through the day Sunday and surface trough of low
pressure will begin to push south across the area Sunday.

Some weak cold air advection will take place Saturday and Sunday
with highs remaining on the mild side in the lower 70s. Lows during
the night will hover in the middle 50s.

Long term Monday through Thursday
Broad upper level troughiness will prevail through Tuesday night
over the eastern united states. Nearly zonal flow will setup by mid
week with a small shortwave trough advancing east into the eastern
portions of the united states by Wednesday and Thursday. Due to the
fast moving systems and long period of cyclonic flow expected across
the area aloft, the atmosphere will be in a chaotic state of change
through the forecast period.

Another wave of low pressure will move east across the forecast area
Monday into Tuesday and then shift east of the area Tuesday night.

Through this process, weak cold air advection will take place into
Tuesday. High pressure with a ridge extending north to the great
lakes will advance east Tuesday night into Wednesday allowing a
return back to warm air advection. Yet another low pressure system
will move quickly east across the central great lakes Thursday night
into Friday morning.

Limited instability is expected across the area through the period
with cold air advancing in during the early periods and this should
limit thunder threat. Then, as warm air advection moves in,
destabilization will take place across the area and increase threat
for thunderstorms.

Cold air advection early in the period will keep temperatures quite
cool. Highs by Thursday may wind up being under forecast due to the
potential for stronger warm air advection and if Sun has a chance to
break through the cloud cover and the showers and thunderstorms.

Aviation 18z Thursday through Tuesday
Most of the shower thunderstorm activity has shifted into ne
oh NW pa along a warm front. Expect most of it to end by late
afternoon. After a break in the precipitation we will await the
lift and moisture from what remains of the tropical depression.

Expect showers and a few thunderstorms to move south to north
into the area overnight with some lower MVFR ceilings also
expected.

Southerly winds will increase through the afternoon and then
remain around 12 knots through the overnight.

Outlook... Thunderstorms with heavy rain possible Friday. Low
chance of brief MVFR in showers Sunday into Monday with a cold
front.

Marine
Southwest flow will persist through Friday in the warm air
advection. A shift to a west northwest direction will take place
Friday afternoon as a cold front moves east of the area. Flow
should be light enough to support 2 to 4 foot waves and avoid small
craft advisories. Increasing winds will take place out of the west
by Saturday evening. May need small craft advisories in the western
half of the lake Saturday evening and over the entire lake by Sunday
morning in westerly flow. This flow will continue into Monday and
then fluctuate in speed through Tuesday.

Cle watches warnings advisories
Oh... None.

Pa... None.

Marine... None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
