area forecast discussion
national weather service cleveland oh
644 am edt Fri aug 23 2019

Synopsis
An expansive area of high pressure will build south toward the
local area from the central and northern great lakes through
the course of the weekend. The high will shift east into new
england on Monday with a cold front moving east across the
region on Tuesday.

Near term through Saturday
Only tweaked the hourly temperatures for first thing this
morning with this early morning update. Previous discussion
follows.

A quiet stretch of weather has arrived and is accompanied by
cool high pressure for the weekend. Yesterdays front has now
settled across the lower ohio valley. Some mid high clouds still
are streaming across northern oh NW pa, but will slip further
south with time today. A healthy crop of fair weather cumulus
will develop for this afternoon and fade toward evening. Still
expecting some lake effect cloud cover tonight with the
northeast flow and the likelihood of a land breeze. Have
continued the slight chance mention of showers too near the
lakeshore late tonight and early Saturday morning. High
temperatures will be running several degrees below normal today
and Saturday with low 70s common. Tonight's lows away from the
lake will dip well into the 50s, with perhaps a couple readings
in the upper 40s.

Short term Saturday night through Monday night
Much of the short term forecast period remains quiet as an
upper ridge hovers over the region. Canadian high pressure will
remain over the great lakes region, allowing for cooler
temperatures than the first few weeks of august, a touch below
average for late august. An upper trough digs into the region on
Monday and will allow for a surface low to approach from the
west on Monday night. Have increasing pops with the incoming
system, but timing between the models is about a 12 hour spread,
so will just have 50 50 pops at a max.

Long term Tuesday through Thursday
The first half of the long term period appears active with a
pattern change underway. An upper trough will move through the
great lakes region on Tuesday and Wednesday, supporting a low
pressure system. The approach of this system is a bit uncertain
as there is some spread with the medium range guidance. In
essence, Tuesday seems to be the wet day over the area with the
best wave of energy aloft entering the area on Tuesday night.

Some residual rain appears possible into Wednesday as the system
pushes through. Some upper ridging enters the region Wednesday
night into Thursday and should more of less keep the forecast
area dry. Temperatures appear seasonable through the period.

Aviation 12z Friday through Tuesday
LargelyVFR for the tafs the next 24 hours with high pressure
slowly building across the great lakes. Only real concern will
be with lake effect cloudiness and the build up of afternoon
cumulus. Most of this will beVFR, but will allow for MVFR at
yng and possibly eri early. Sct to bknVFR for a period of time
in the early afternoon for all others. Northeast flow will be 5
to 10 knots and slightly stronger near the lakeshore. On and off
lake clouds, likelyVFR, will continue tonight for the lakeshore
terminals.

Outlook... NonVFR possible with a chance of showers and
thunderstorms on Monday afternoon and Tuesday.

Marine
Northeast flow will be present on the lake today and tonight.

This unfavorable flow will probably be weak enough to not
generate high enough waves for a small craft advisory, but there
will be enough of a chop over the lake where it will be a rough
day on the lake. Some convergence over the lake this evening
will perhaps generate a couple showers and with cooler air over
the water, waterspouts are possible. High pressure will be north
of the lake for Saturday and Sunday, allowing for light
easterly flow over the basin. Winds will shift around to the
southeast ahead of a low pressure system on Monday and increase
to 15 to 20 knots. The low will pass north of the lake on
Tuesday and allow for increased southerly flow on Monday night
into Tuesday before becoming light out of the southwest for
Tuesday night and beyond.

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.
