Area Forecast Discussion National Weather Service Cleveland OH 127 AM EDT Sun Apr 21 2024

High pressure over the area will persist into Monday before a low pressure system moves into the region on Tuesday. This low will move a warm front north on Tuesday morning, followed by a cold front Tuesday night. A trough will linger before high pressure builds in on Thursday.

1:25 AM Update: As mentioned in prior updates, a stratus deck has persisted across most of the area and makes frost / freeze potential questionable for early this morning. Parts of Northwest OH, along with some of our southern fringes (i.e. Knox) have seen some clearing and have cooled into the mid to upper 30s.
Interior Northwest PA has also cooled into the 30s (quite a bit of spread between about 33-38 degrees) due to earlier clearing.
Given light winds and low dew points, if any additional holes develop temperatures can locally drop into the low to mid 30s.
Will keep the Frost Advisory going overnight and monitor trends...overall there will be less frost than originally thought possible with lows struggling to dip below freezing as too. May be able to cancel at least part of the headline with the main package around 3:30-4:00 AM.

Previous Discussion...
A cold front has moved east of the area, leaving much cooler temperatures in its wake. Highs this afternoon have only climbed into the mid to upper 40s, but with gusty northwest winds it feels closer to the upper 30s to low 40s. These colder temperatures may pose a risk to outdoor plants tonight as lows drop into the low to mid 30s across the area, but various other conditions will likely inhibit widespread frost or freezing conditions. Overall, the current airmass is fairly dry with dewpoints lingering in the 20s, but with a shortwave moving east across the area, there has been cloudy skies today which is expected to persist into portion of tonight. This may allow temperatures to remain a bit warmer (although still in the low to mid 30s), but with it still being so cold and winds expected to be calm to 5 knots, have opted to include patchy frost in the forecast for all counties except along the lakeshore. As a result of the frost potential, coupled with the cold temperatures, have opted to issue a Frost Advisory for those counties tonight into early Sunday morning. In addition, there is a small chance that cold 850mb temperatures moving across a relatively warm lake (for this time of year) may produce enough instability to get isolated sprinkles out of it. Confidence is very low in any of this reaching the surface so opted to not include it with this update, but will continue to monitor the airmass in the coming hours.

On Sunday, high pressure will persist and temperatures will climb into the upper 40s out east and the mid 50s for western counties.
The areas that will see the warmest temperatures should see some peaks of sun as the aforementioned shortwave moves east. By Sunday night, all these clouds should move out of the area, allowing for enhanced radiational cooling and temperatures falling again into the low to mid 30s. Although the high persists, moisture values are expected to increase a bit with dewpoints climbing into the upper 20s to low 30s. All of this coupled with light and variable winds will result in prime conditions for widespread frost development Sunday night.

Fair weather is expected on Monday through Monday night as a ridge at the surface and aloft builds and eventually crests E'ward over our region, and is accompanied by a stabilizing subsidence inversion. Late afternoon highs are expected to reach the lower to mid 50's in NW PA and the mid 50's to mid 60's in northern OH. The coolest readings are expected within several miles of Lake Erie since sufficient daytime heating of surrounding land and a weak synoptic MSLP gradient are forecast to allow a lake breeze circulation to form and penetrate several miles inland during the afternoon through early evening, especially from roughly Lorain County to Erie County, PA. Overnight lows are expected to reach the mid 30's to upper 40's during the wee hours of Tuesday morning and be followed by moderating temperatures by daybreak as low-level WAA strengthens on the backside of the surface ridge.

A potent shortwave trough approaches our CWA from the Upper Midwest and Upper Great Lakes on Tuesday before advancing generally E'ward across northern OH and NW PA Tuesday night. At the surface, the attendant trough overspreads our region from the north and west, and the cold front is forecast to sweep generally E'ward through our CWA Tuesday night. Scattered and periodic rain showers are expected due to moist isentropic ascent aloft, ahead of the front, and low-level convergence/associated moist ascent along the front. These lifting mechanisms should release enough elevated instability for the development of isolated thunderstorms Tuesday night. Daytime highs should reach mainly the lower to mid 60's on Tuesday. Overnight lows should reach the lower to mid 40's around daybreak Wednesday due in part to low-level CAA behind the cold front.

Primarily fair weather is expected on Wednesday through Thursday night as a ridge at the surface and aloft builds into our region from the Upper Midwest and the northern/central Great Plains, eventually begins to crest generally E'ward over our region, and is accompanied by a stabilizing subsidence inversion. However, isolated rain showers along the upper-reaches of the aforementioned cold front should exit NE OH and NW PA by the afternoon or early evening hours of Wednesday. Daytime highs should reach the upper 40's to lower 50's in NW PA and the upper 40's to upper 50's in northern OH on Wednesday. Overnight lows should reach mainly the lower to mid 30's around daybreak Thursday morning and frost is possible. On Thursday, daytime highs should once again reach the upper 40's to lower 50's in NW PA and mainly the 50's to 60F in northern OH as lingering low-level CAA behind the front eventually transitions to low-level WAA on the backside of the surface ridge as the ridge advances generally from west to east. Overnight lows should then reach the 30's during the wee hours of Friday morning before strengthening low-level WAA allows readings to moderate toward the 40F mark or so by daybreak Friday morning.

The surface portion of the aforementioned ridge continues to exit gradually E'ward on Friday through Saturday as the portion of the ridge farther aloft crests over our region and then also begins to exit gradually E'ward. Simultaneously, the next shortwave trough approaches from the north-central and central United States, and eventually the western Great Lakes, while the attendant surface trough overspreads our CWA from the west. Moist isentropic ascent aloft on the backside of the ridge and ahead of the shortwave trough axis should generate scattered and periodic rain showers on Friday through Saturday. The ascent may release enough elevated instability to generate isolated thunderstorms Friday night into Saturday.
Daytime highs should reach mainly the 60's on Friday and be followed by overnight lows reaching mainly the mid 40's to mid 50's around daybreak Saturday. Daytime highs are forecast to reach the mid 60's to lower 70's in NW PA and mainly the lower to mid 70's in northern OH on Saturday as low-level WAA persists.

AVIATION /06Z Sunday THROUGH Thursday/
VFR ongoing and is expected to persist through the TAF period.
Mainly dealing with mid-deck around 5 to 6kft early this morning. Some spots such as near TOL where that deck has broken up to less than a ceiling, though at most sites expect this BKN to OVC deck to persist early this morning. As a weak shortwave passes between 12-15z we may see ceilings lower to the 4 to 5kft range. By mid to late afternoon, these ceilings should scatter out with mainly clear skies persisting into tonight.

West-northwest winds and generally 3 to 8 knots continue early this morning, and are expected to increase to around 10 knots today. Periodic gusts up to 20 knots are possible at CLE/ERI.

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

Small Craft Advisory remains in effect until 8 PM EDT this evening from Vermilion to Ripley. A trough lingers over Lake Erie before a ridge builds from the north-central United States on Sunday through Monday. Primarily W'erly to NW'erly winds around 10 to 20 knots ease to 15 knots or less tonight before shifting to W'erly to SW'erly and increasing again to around 10 to 20 knots on Sunday. Waves as large as 3 to 6 feet subside to 3 feet or less by daybreak Sunday. On Sunday, waves should rebuild to as large as 3 to 6 feet, especially in open waters east of the Islands. The latest forecast indicates another Small Craft Advisory is not needed in any of our nearshore zones on Sunday, but forecast trends will be monitored.
Winds are then expected to ease to around 5 to 10 knots and become variable in direction Sunday night into Monday as waves subside gradually to 2 feet or less.

Winds become S'erly to SW'erly around 15 to 25 knots on Monday night through Tuesday as the ridge departs generally E'ward and interacts with a cold front approaching from the west. Waves build to as large as 4 to 7 feet and will trend largest in open U.S. waters and Ontario waters where fetch is maximized. Another Small Craft Advisory will probably be needed. SW'erly winds veer to NW'erly Tuesday night as the cold front sweeps E'ward across the lake and waves are expected to be as large as 3 to 6 feet. NW'erly to NE'erly winds are expected on Wednesday through Thursday as another ridge builds from the Upper Midwest. These winds will ease gradually to 5 to 15 knots. Waves are forecast to subside gradually to 3 feet or less by daybreak Thursday.

OH...Frost Advisory until 8 AM EDT this morning for OHZ003-006-008- 013-014-017>023-027>033-036>038-047.
PA...Frost Advisory until 8 AM EDT this morning for PAZ002-003.
