Area Forecast Discussion National Weather Service Cleveland OH 635 AM EDT Sun Apr 21 2024

High pressure remains in control of the weather through Monday night. A low pressure tracks through the Great Lakes on Tuesday, lifting a warm front across the area Tuesday morning followed by a cold front Tuesday night. Troughing lingers behind this system on Wednesday before high pressure returns on Thursday.

Generally quiet weather for the near term. A vort max and subtle surface trough axis will move through this morning. Can't entirely rule out the combination of these features picking up a sprinkle or flurry off of Lake Erie into far Northeast OH or Northwest PA this morning (as confirmed by a few extremely light radar returns east of Cleveland), though a dry airmass should preclude any measurable precip so no POPs for it. Otherwise, another subtle low to mid-level trough axis moves through early this afternoon. It has remained mostly cloudy overnight and will remain mostly cloudy for most of today as these features move through. Confluence aloft behind the trough axis as it departs into this evening should allow for a clearing trend from northwest to southeast, with the loss of heating near sunset further aiding in clearing skies into tonight. The eastern lakeshore should also begin clearing a bit sooner this afternoon as a lake shadow develops. Expect partly to mostly clear conditions to then persist tonight and Monday, though likely with enough low level moisture for a decent cumulus field to develop Monday afternoon.

Highs today will rebound a bit from Saturday, ranging from the upper 40s to near 50 in far Northeast OH and Northwest PA to the mid to upper 50s along the I-75 corridor. Lows tonight will generally range from the low to mid 30s inland to the upper 30s to near 40 along the immediate lakeshore. We will see a more traditional radiational cooling setup tonight so expect some variance, with rural areas and more sheltered / lower spots cooling more (some typical cold spots likely getting below freezing) while urban areas and those on hilltops cool a bit less. Highs on Monday will range from the mid to upper 50s in Northwest PA to the low to mid 60s in Ohio. Winds will be fairly tranquil this period, with some gusts to 20-25 MPH possible this afternoon in Northwest OH and near the lakeshore farther east. Gusts Monday afternoon may reach 20 MPH in Northwest OH.

More expansive cloud cover than expected kept temperatures a few degrees warmer than forecasted overnight into this morning and significantly limited frost potential. Canceled the remaining portions of the Frost Advisory for this morning shortly after 6 AM. It's possible a few areas got some frost where skies briefly cleared and temperatures dropped to 33-35 degrees, from portions of Lucas/Ottawa east-southeast to portions of Medina/Summit, along with interior Northwest PA east of I-79...though overall, the clouds "spoiled" the frost setup.
A much more traditional radiational cooling / frost setup for tonight into Monday morning, assuming we actually manage to clear the clouds (we should have a better chance with large scale subsidence behind the departing shortwave). Winds will be light and should decouple across most of the area, save for perhaps a few hill tops and near the lake. We will need a frost headline for most of the forecast area for tonight into Monday morning and may need to think about targeted freeze warnings for the typically colder spots (parts of interior northern Ohio, such as near Wooster, along with interior Northwest PA). While we were able to get this morning's headline completely off the board, some neighboring WFOs still have frost/freeze products active for this morning. To give day shift a better chance to collaborate where new headlines are needed, the timing of said headlines, and if any areas need a Freeze Warning vs just a Frost Advisory, will not raise tonight's headlines yet.

Cloud cover will be on the increase Monday night into Tuesday ahead of an upper level trough sliding southeast into the Great Lakes Region. South to southwest winds will be breezy on Tuesday, advecting a warmer airmass north into the area. Dewpoints will start the day in the 30s on Tuesday and take some time to moisten. Little to no instability is forecast on Tuesday in the warm sector given an extensive mid cloud deck and low boundary layer moisture but rain is forecast to spread west to east across the area Tuesday afternoon and night. The cold front trails as the surface low tracks well northeast into Quebec, pushing south of Lake Erie after midnight Tuesday night. Will carry a chance of thunderstorms with the front although instability will still be limited. Highs on Tuesday will be in the lower 60s area wide, dropping back into the upper 40s to lower 50s for highs behind the front on Wednesday.

High pressure builds in quickly behind the front on Wednesday night.
It looks like cloud cover should clear, allowing areas of frost to form Wednesday night. It is also possible that much of the area could see sub-freezing conditions.

High pressure with nearly full sun overhead on Thursday should contribute to temperatures warming about 5 degrees, except near Lake Erie. High pressure shifts to New England on Friday as upper level ridging builds overhead. Temperatures will trend warmer through the extended, especially behind a warm front that will lift north Friday night. It is possible that we could see chances of showers and thunderstorms as early as Friday afternoon but better chances will be through Saturday as a shortwave rounds the ridge aloft, kicking off activity. Temperatures will be above normal (65-75F) again by Saturday.

AVIATION /12Z Sunday THROUGH Thursday/
VFR ongoing and is expected to persist through the TAF period.
A broken to overcast deck in the 4-5k foot range will persist this morning into this afternoon. By mid to late afternoon these ceilings should scatter out with mainly clear skies persisting tonight. Localized valley fog is possible late tonight, but with a dry airmass it should be localized and confidence is not currently high enough to include in any TAFs.

West-northwest winds are expected to increase to around 10 knots later this morning through this afternoon. Periodic gusts up to 20 knots are possible at CLE/ERI. Winds will become light and variable quickly after sunset this evening.

Outlook...Non-VFR possible in showers Tuesday. Non-VFR may persist into early Wednesday.

Winds back to southwesterly today but remain elevated east of Cleveland at 15-20 knots. Waves of 3 to 5 feet can be expected in the open waters. A ridge expands east over Lake Erie on Monday with light winds and waves. South to southwest winds will increase to 15- 25 knots on Tuesday as low pressure moves east across the Upper Great Lakes. A trailing cold front will move southeast across Lake Erie Tuesday night with a wind shift to the northwest and post frontal winds of 15 to 20 knots. It is unclear if a Small Craft Advisory will be needed with the offshore flow on Tuesday but will likely be needed east of Vermilion as flow becomes onshore and waves build on Wednesday.

High pressure will build east across the Great Lakes Region Wednesday night through Thursday night. A warm front will lift north across the lake Friday night with southerly winds increasing behind it.
