Area Forecast Discussion National Weather Service Cleveland OH 312 PM EDT Wed Apr 17 2024

A cold front brings showers and storms through the area this evening into early tonight. Brief high pressure Thursday, followed by another cold front late Thursday night into early Friday. Much cooler into the weekend.

Destabilization with MLCAPE to 1500J/kg continues ahead of the line of convection moving through the western portion of Ohio at the time of this issuance. Surface dewpoints currently surging into the lower 60s in western Ohio, and expecting winds at the surface to back as the cold front currently moving into Indiana approaches. This will serve to increase the 0-1km helicity ahead of the convection assisting in formation of rotating updrafts. Also have good deep layer shear and dry air punch in the mid levels seen in the water vapor satellite imagery, and ultimately have many ingredients coming together for the severe weather threat unfolding across the region. Expecting a progressive event and efficient tracking of the activity through the CWA in a few hours time with the higher POPs exiting just after 00Z Thursday. One thing to consider with this severe weather threat is with the bowing of the broad scale line of convection if it cuts off some of the southwesterly oriented inflow to the north of the apex. Does not eliminate the threat for storms, but could slightly lessen the severe chances a bit further north.

Upon exit, lower level clouds advect back into the region, a modest cool down ensues, and brief upper level/surface ridging makes its way back into the region for Thursday. Cooler day expected with afternoon breaks in the clouds and a rapidly approaching cold front once again from the west in the continued progressive pattern. This secondary cold front will represent a more significant change of airmass heading into the short term forecast period. POPs enter after 00Z Friday west to east into Friday night.

A strong cold front will bisect the region Friday morning as a broad mid/upper trough swings into the Great Lakes, with an associated closed mid-level low lifting into the James Bay vicinity. This will usher in some late season cold air for the weekend as 850 mb temps fall to -3 to -5 C by Saturday as the trough axis remains across the Great Lakes and the closed low continues to spin over James Bay.
Showers and a few pockets of thunder will exit eastern areas rather quickly Friday morning as the front moves east, leaving most areas dry Friday afternoon. However, the broad cyclonic flow, westerly boundary layer winds across the lake, strong cold air advection, and aforementioned 850 mb temps will lead to enough lake induced instability for lake-effect showers over far NE Ohio and NW PA later Friday into Saturday, so maintained slight chance to chance PoPs there. A limiting factor is dry air and a quick increase in boundary layer shear, so it will not amount to much, but pattern recognition points to light precip hanging on in these areas. Some snow could mix in Friday night into Saturday morning in the highest elevations of southern Erie and northern Crawford Counties. Broad surface high pressure over the Plains and Midwest will finally extend its ridging east enough Saturday afternoon and Saturday night to shut down any lake-effect precip, so have all areas dry by Saturday night.

The main story with this cold spell will be frost/freeze potential.
Highs in the upper 50s/low 60s Friday will only rise into the upper 40s/low 50s Saturday. Lows Friday night should stay up enough to prevent frost due to winds staying in the 10-20 knot range. The coldest spots of NW PA should even stay in the upper 30s given the winds and clouds/precip off the lake. Lows Friday night will range from the upper 30s to low 40s across the region. However, Saturday night could spell trouble as the surface ridging extending into the region leads to decreasing winds and more potential for clearing skies. At this time, lows Saturday night look to range from the low to upper 30s, with the coldest temps in eastern Ohio and interior NW PA, as well as around the central highlands and along the US 30 corridor. With the vegetation really beginning to sprout over the past week, we have begun the Spring frost/freeze program, so headlines are expected Saturday night.

The mid/upper troughing over the Great Lakes and eastern CONUS will gradually relax Sunday through early next week, but the closed low will continue to spin over James Bay keeping a relatively cool WNW flow pattern in place through early to mid week. Broad surface high pressure extending into the Ohio Valley Sunday will gradually move east Monday, reaching the Mid Atlantic coast by Tuesday leading to gradually rebounding temperatures to near to below normal for this time of year. Frost/freeze headlines are possible again Sunday night, especially for eastern Ohio and NW PA. Deterministic and ensemble guidance are in good agreement on a northern stream mid/upper shortwave diving through the Upper Midwest and Great Lakes Tuesday into Wednesday which will reinforce and deepen the longwave troughing over the eastern CONUS by mid week, but timing of this feature varies among the guidance leading to low confidence on the timing of showers. For now, kept the blended PoPs which has chance PoPs arriving late Monday night and Tuesday and continuing into Wednesday.

Highs in the low/mid 50s Sunday will warm into the upper 50s/low 60s Monday and solid low 60s Tuesday. Highs should then cool into the mid 50s to around 60 by Wednesday.

AVIATION /18Z Wednesday THROUGH Monday/
Gusty winds 25-35kts mainly out of the southwest ahead of lines of thunderstorms moving into western Ohio at this hour. There is a potential for strong wind gusts/hail and isolated tornadoes with this activity through the 01Z Thursday. TAF carries G45KT in TEMPO with IFR thunderstorms as the lines of convective activity move west to east. Generally gave 2hr windows for the stronger thunderstorm activity in timing the storms as they should be relatively quick movers with limited development of additional storms behind the main lines. This is in conjunction with a cold front that will trail the storms, and expect a wind shift to a more westerly direction behind the cold front which will be through the area by 03Z Thursday. Winds will ease behind the front as well eventually below 12kts overnight. Brief MVFR ceilings possible later overnight behind the main thunder storm activity lingering into the daylight hours Thursday.

Outlook...Non-VFR possible for Friday into Saturday in rain.

A line of showers and thunderstorms will cross Lake Erie this evening leading to locally higher winds and waves and cloud to ground lightning strikes. Otherwise, relatively quiet marine conditions are expected over the next couple of days with winds and waves below Small Craft criteria. Winds will veer to WSW at 10-15 knots tonight behind the cold front, becoming light and variable by Thursday evening. Winds will then become S to SW Thursday night and increase to 10-15 knots before turning W and increasing to 15-20 knots Friday behind another cold front. This may build waves over 4 feet in the central and eastern basins, so Small Craft headlines are possible Friday. W winds of 15-20 knots look to continue well into Saturday with waves above 4 feet at times, so Small Craft headlines are possible through Saturday. Winds will turn NW and gradually decrease to 10-15 knots Saturday night and Sunday, becoming SW at 5- 10 knots Sunday night and Monday.
