Area Forecast Discussion National Weather Service Cleveland OH 651 AM EDT Thu Apr 22 2021

SYNOPSIS. A weak surface trough will linger across the area through this morning. High pressure ridging will extend north into the area through today into Friday. A low pressure system will approach the region on Saturday with high pressure ridging returning by Sunday.

NEAR TERM /THROUGH FRIDAY/. Snow showers have diminished across the area this morning, but black ice has become the bigger problem with multiple reported accidents since early this morning. Wet pavement from the previous evening's snow has frozen under ideal conditions (i.e. clear skies, sub-freezing temperatures, and relatively light winds). The threat for black ice should quickly diminish following sunrise.

Previous Discussion . Snow is beginning to diminish across the region early this morning as drier air arrives behind a surface trough. A few lingering lake effect snow showers can't be ruled out across NW PA through the morning as another weak embedded shortwave trough swings south across the eastern Great Lakes. Otherwise, anticipate a dry morning across the entire area.

By this afternoon, a stronger shortwave trough will pivot south across the eastern Great Lakes, which could kick off some diurnally- driven isolated rain showers across the southern tier of the area, though confidence remains low given the antecedent low-level dry air. Better confidence in precipitation in the form of rain and/or snow showers resides across extreme NE OH and NW PA later this afternoon and evening as a subtle increase in low-level moisture associated with the shortwave passage occurs. Think that snow may be the more primary precipitation mode across this area given both a cloudy DGZ and omega maximized within the DGZ. Moderate levels of low-level 0-3 km CAPE could also result in some brief periods of heavier bursts of snow. By the late evening hours, dry air and upper ridging quickly arrive from the west, ending any lingering precipitation across the region and ushering in clear skies overnight. Have issued a Freeze Watch for Wyandot, Marion, Morrow, and Knox Counties for tonight as temperatures may reach the lower 30s under clear skies. An upgrade to a freeze warning is likely by later this morning after the current warning expires.

Friday's weather will be quiet, dry, and mostly sunny with some occasional mid and high cloud cover under surface high pressure. High temperatures will finally return to slightly above normal, in the lower 60s.

SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/. Overall pattern change is shaping up for the weekend as flow becomes more progressive with a warming trend in the works. Upper level ridge will begin to build into the local area Friday night followed by a fast moving upper level trough and associated positive vorticity maximum. Expecting this feature to move through the area fairly quickly and bring a shot of moisture associated with it Saturday and Saturday night. Moisture exits to the east by Sunday morning with the trough. Surface low is expected to move east across the Ohio Valley by Saturday afternoon keeping the warm front south of the area. Even so, moderating air mass will bring milder temperatures to the local area during this forecast period. Surface low pressure will shift to the east Sunday allowing surface high pressure to build into the region Sunday and Sunday night. Highs will be in the 50s and lows will be in the 40s through Sunday but dropping into the 30s with slight cold air advection under the high pressure building into the area.

LONG TERM /MONDAY THROUGH WEDNESDAY/. Amplifying upper level ridge will move east into the local area Monday allowing surface high pressure over the region to shift east. This will set-up a strong warm air advection pattern heading into the middle of the week. The surface high pressure will continue to build over the western Atlantic Ocean during this period while surface low over the northern Plains states continues to deepen. The return southerly flow will push the warm front well north of the area by Monday evening with a strong surge of warm air into the region. Very limited moisture is expected with the low pressure system and warm front so expecting fair weather to persist Monday into Tuesday. Deep digging upper level trough will dive southeast into the central Plains states by Wednesday afternoon and become positively tilted. The trough will nearly stall just west of the area keeping the strong warm air advection flow in our favor. This will allow temperatures to warm well into the 70s Tuesday and Wednesday and even perhaps 80s. Will need to monitor situation by Thursday as cold front approaches with area with a pre-frontal trough and instability for potential for severe weather.

AVIATION /12Z Thursday THROUGH Monday/. VFR across the TAF sites this morning with mainly VFR to prevail through the TAF period. Exception may be at ERI where a brief hour or two window of heavier snow and/or rain showers may sweep across the area later this afternoon and evening.

Winds are generally light this morning out of the west/northwest, less than 10 knots. Winds will increase through today, near 15 knots with gusts up to 25 knots and perhaps closer to 30 knots at ERI.

Outlook . Non-VFR expected with widespread rain Saturday afternoon through Saturday night.

MARINE. Winds on the lake are expected to gradually increase this morning and will need to issue a small craft advisory through about 8 PM this evening from approximately Vermilion east. Otherwise, winds diminish tonight and become southwest by Friday at 15 to 25 knots. May need another small craft advisory for Friday. Winds diminish again Friday evening into Saturday night. A northwest flow sets up for Sunday and increases once again when another small craft advisory may be needed through Sunday night. Monday will see light and variable winds as high pressure begins to build into the area.

CLE WATCHES/WARNINGS/ADVISORIES. OH . Freeze Warning until 10 AM EDT this morning for OHZ003-006-017- 027-036-037-047. Freeze Watch from late tonight through Friday morning for OHZ027-036-037-047. PA . None. MARINE . Small Craft Advisory until 2 AM EDT Friday for LEZ146>149.
