AREA FORECAST DISCUSSION National Weather Service Wilmington OH 730 PM EDT Tue Apr 23 2024

SYNOPSIS
A mid-level trough and a cold front will bring rain to the area this evening. Drier and cooler weather will then be expected for Wednesday and Thursday. As a ridge moves east of the region on Friday, additional chances of precipitation will begin.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/
A fairly solid band of precipitation has developed from north of St Louis through southern Ontario. This rain has developed ahead of a mid-level shortwave, and roughly coincident with a plume of theta-e at 850mb/700mb. It will still take a while for this feature to pivot through the ILN CWA, but most locations will at least receive a couple hours of rainfall from late this afternoon into the evening, with some chances persisting into the overnight hours.

A cold front will then move into the area later overnight, bringing little if any additional precipitation -- as the air mass will be drying out. Some convection is expected upstream of the area, so it is not out of the question that a few leftover showers could get into the northern ILN CWA in the 06Z-12Z time frame.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/
The surface cold front will be continuing to move south through the ILN CWA on Wednesday morning, as a surface high builds into the Great Lakes. Model soundings suggest that stratocumulus clouds may not dissipate immediately, so some sky cover will be maintained through the morning, particularly for parts of central Ohio.

The main concern through this part of the forecast is in frost/freeze potential on early Thursday morning. The high will be centered over southern Ontario at 12Z Thursday, and there may still be some light easterly flow in place. Otherwise conditions will be ideal for cold temperatures, especially in the northern and northeastern portions of the ILN CWA (and adjacent locations in other CWAs). Have coordinated a Freeze Watch for some counties where temperatures on Thursday morning appear fairly likely to reach 32 degrees or lower.

LONG TERM /THURSDAY THROUGH TUESDAY/
Large scale ridging continues to move into the region Thursday while the surface high pressure continues to slowly be shunted east toward the New England area. Partly cloudy to mostly sunny skies dominate and temperatures reach the upper 50s/low 60s, which is still a few degrees below normal. The high continues to pushed off to the east as the next weather maker moves in from our west. This allows for return southerly flow to dominate and a warming trend ensues. Overnight lows into Friday fall to the upper 30s/ low 40s and high clouds begin to spill over into the region.

By Friday late morning, the warm front of the low to our west will be lifting into the Ohio Valley, pushing showers out ahead of it. Instability looks pretty limited through this time frame, so widespread storms are not anticipated, but rumbles of thunder may be heard. By afternoon/evening hours, a strong LLJ overtakes the region and some of this energy is mixed down to the surface, resulting in the onset of gusty conditions that will hang around for several days. Temperatures rise to the upper 60s/ low 70s.

The warm front continues to lift through the region and by Friday overnight hours, some additional instability builds into the area, resulting in continued chances for thunder as the ILN CWA becomes warm sectored. Overnight lows fall to the upper 50s.

The area remains sandwiched under strong southerly flow between the low pressure to our northwest and the high pressure that has been creeping toward Bermuda for the weekend. This results in highs in the upper 70s with Tds in the upper 50s and wind gusts up to 30 MPH, particularly in west central Ohio.

By Sunday night, the upper level trough will have moved toward the western Great Lakes, dragging a secondary surface feature along with it. This brings the associated cold front into the Ohio Valley, forcing showers and storms out ahead of it for Monday.

AVIATION /00Z WEDNESDAY THROUGH SUNDAY/
Flight conditions will deteriorate tonight as moisture along a front moves to TAF sites. Showers are forecast at all sites early in the forecast as moisture convergence and lift increase ahead of the front. While the showers will be relatively brief in duration, lasting a few hours, ceilings dropping to MVFR will persist through a good part of Wednesday until high pressure and dry air take over. CVG and LUK should be the first to improve to VFR around 16z, with VFR returning to the remainder of sites by the end of the forecast period. Winds may gust over 20 knots at the start, with speeds falling off to around 10 knots as the pressure gradient relaxes behind the front. Wind direction will shift from southwest to north as the front progresses east.

OUTLOOK...MVFR conditions possible Friday night into Saturday.
