Area Forecast Discussion
National Weather Service Cleveland OH
343 PM EDT Mon Apr 21 2025

.SYNOPSIS...
Low pressure over the northern Great Lakes will pull a cold
front east across the region early this evening. The low will
lift into Quebec late tonight and Tuesday allowing high pressure
to build over the southern Great Lakes. The high will slide into
the eastern Great Lakes by Wednesday allowing a warm front to
lift across the region.

&&

.NEAR TERM /THROUGH TUESDAY NIGHT/...
The focus of the forecast is on the line of low-topped convection
currently moving through NE Ohio. This convection is immediately
along the cold front, where strong frontogenetic forcing is being
maximized beneath the right entrance region of a 90-100 knot H3 jet
streak and associated 50-60 knot H5 jet streak. A mid-level dry slot
has allowed sufficient clearing ahead of the line for about 500
joules of SBCAPE and 250 joules of MLCAPE per the latest
mesoanalysis, so expect the convection to continue through the rest
of NE Ohio and through NW PA by 21Z. Deep layer effective bulk shear
of 40-50 knots oriented mainly orthogonal to the line and 0-3Km
shear of 35-45 knots also oriented orthogonal to the line is leading
to line breaks, with some individual cells. This will maintain the
risk for isolated embedded supercells capable of a brief spin up
tornado and marginally severe hail, in addition to damaging winds.
This will continue to be monitored through late afternoon, although
the threat will remain very marginal and localized.

The other issue is synoptic gradient winds. Observations across NW
and north central Ohio have recorded SW winds of 20-25 knots gusting
to 30-40 knots at times behind the cold front. This appears to be
due to the rapid clearing and pressure rises behind the front
allowing for a well-mixed profile into a 40-50 knot low-level jet.
In fact, surface temperatures have been warmer behind the front in
the cold air advection since there has been more sunshine, so the
mixing down of these winds is not too much of a surprise. For the
most part, obs have stayed just below advisory criteria, so will
continue the SPS the rest of the afternoon for these gusty winds.
Expect the winds to diminish rather quickly by 00Z.

By tonight, there will be nothing to worry about as the mid/upper
shortwave trough shears out across the eastern Great Lakes and the
associated occluded low continues to fill as it reaches Hudson Bay
by Tuesday morning. This will allow for quasi-zonal flow to return
across the CONUS for Tuesday and Tuesday night, with surface ridging
building across the Great Lakes. This will lead to quite a bit of
sunshine for Tuesday, although temperatures will average 10-15
degrees cooler as the front pushes into the Ohio Valley, especially
near the lakeshore where the flow is onshore. The surface ridging
will start to drift east Tuesday night with return southerly flow
redeveloping, so the milder air just to the south will make its
return northward. A few showers are possible with the isentropic
ascent ahead of the warm front late Tuesday night, but given the dry
low-level airmass, kept the forecast dry for now.

Lows tonight will dip into the low/upper 40s, with highs Tuesday
averaging low/mid 60s, except upper 50s/low 60s near the lake.
Milder lows of mid 40s to low 50s are expected Tuesday night, except
in NW PA where the lingering colder airmass will result in
temperatures falling to around 40.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
The general expectation for the short term period looks fairly quiet.
The overall weather pattern will be a zonal or westerly flow during
the middle of the week. A warm front will lift northward across the
area on Wednesday The better chance for shower or two will be
west of the region and closer to Northwest Ohio on Wednesday. High
temperatures will range from the upper 60s to the upper 70s. A weak
area of high pressure will build back over the area late Wednesday
into Wednesday night. The next shortwave will track along in the
zonal flow from the Central Plains into the Midwest on Thursday.
Southerly flow ahead of this approaching system will advect in
warmer air and moisture. Isolated rain showers may return back into
the area late on Thursday into Thursday night. High temperatures on
Thursday will range from the middle 70s to the lower 80s.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
The shortwave trough and weak area of low pressure will track
through the Lower Great Lakes region and Upper Ohio Valley on
Friday. Rain showers will be likely with a chance for thunderstorms
Friday into Friday night. High temperatures will range from the
middle to upper 70s on Friday. A cold front will slide through
Friday night behind the exiting surface low pressure system.
Saturday will be much cooler with scattered rain showers ending from
west to east. High temperatures this weekend will be in the upper
50s to middle 60s. Overnight low temperatures will be in the lower
to middle 40s.

&&

.AVIATION /18Z Monday THROUGH Saturday/...
Light showers will continue to affect KCAK, KYNG, and KERI
through 19Z or so, but mainly VFR cigs and vis are expected. The
bigger concern is a line of heavier showers and thunderstorms
currently approaching KCLE and KMFD. This line is expected to
sweep east through all of NE Ohio and NW PA through 21Z and will
bring brief heavy rain, occasional lightning strikes, and wind
gusts of 40-50 knots. Used TEMPO groups to time this line. VFR
is expected ahead of and behind the line.

SW synoptic winds are gusting to 30-40 knots behind the cold
front across NW and north central Ohio, so raised gusts at all
terminals this afternoon since clearing in the cloud cover, cold
air advection, and good mixing into a sub 50 knot 850 mb jet
will support these winds continuing east for mid to late
afternoon behind the front/convective line. The winds should
diminish pretty fast by mid evening, decreasing to W at 10-15
knots tonight into Tuesday.

Outlook...Non-VFR possible with scattered rain showers and
thunderstorms Thursday afternoon through Friday.

&&

.MARINE...
A strong cold front is currently tracking across Lake Erie this
afternoon. Gusty southwest winds 15 to 25 knots will become westerly
this evening and overnight. Small Craft Advisories have been issued
for the rest of the afternoon through early Tuesday morning for the
gusty westerly flow and higher waves. High pressure will build into
the region Tuesday and the flow will become variable at 10 knots or
less by later in the day. High pressure will move east of the lake
Wednesday, allowing a warm front to approach the lake. A light
easterly flow will return Wednesday followed by a southeasterly to
southerly flow by Thursday. A low pressure system will approach the
lake by Friday and a southerly to southeasterly flow 10 to 15 knots
will overtake the lake on Friday.
