.SYNOPSIS... High pressure drifts east through Monday as a cold front moves into the Great Lakes region Monday night into Tuesday. The front will glide east across the local area on Tuesday before another area of high pressure builds across the Great Lakes region Wednesday and Thursday. Another cold front will move east across the Great Lakes region Friday into Saturday.
&&
.NEAR TERM /THROUGH MONDAY NIGHT/... High pressure will exit to the east through the near term as an upper level trough approaches the Great Lakes region from the west. Prolonged dry period will end as a surface cold front approaches the local area Monday night. Showers begin to push into the region ahead of the front Monday night though most of the precipitation will occur with the frontal passage on Tuesday, more on that in the short term discussion below.
Above normal temperatures are expected to persist ahead of the passage of a surface cold front. Overnight lows tonight will settle in the low to mid 50s east of I-71 and mid to upper 50s west of I- 71. High temperatures Monday afternoon will rise into the low to mid 80s areawide. Mostly cloudy skies on Monday night will allow for warm overnight lows to settle in the upper 50s to lower 60s.
&&
.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... The aforementioned surface cold front will glide east across the local area during the day on Tuesday. Showers will primarily remain focused along the surface boundary. Can`t rule out some isolated thunderstorms in the afternoon where better upper level support exists and MLCAPE increases to 500-750 J/kg. Overall rainfall amounts will generally range between 0.50-0.75 inches, with locally higher amounts 0.75-1.00 inches possible along the lakeshore from Cleveland east. Any lingering showers will exit the region to the southeast as Canadian high pressure establishes itself across the Great Lakes region.
Slightly cooler on Tuesday with highs rising into the lower 70s, still a few degrees above normal for early October. Much cooler airmass in place behind the cold front and as the Canadian high enters the region. Both of these features will allow for below normal highs in the lower 60s by Wednesday. Lows Tuesday night settle in the mid to upper 40s before dropping into the mid to upper 30s Wednesday night. Confidence in frost is increasing Wednesday night with DESI NBM probabilities of a minimum temperature below 36 degrees increasing to 60-80% across portions of inland Northeast Ohio and Northwest Pennsylvania with locally higher probabilities across typical cool spots in eastern Erie and Crawford Counties in Pennsylvania.
&&
.LONG TERM /THURSDAY THROUGH SUNDAY/... Canadian high will largely remain in place through much of the long term period. A weak cold front is progged to push east across the area Friday into Saturday. Precipitation chances with this front remain minimal (less than 20%) and confined to typical Snowbelt locations on Saturday. Highs remain a few degrees below normal Thursday before highs return to near normal values in the upper 60s Friday into the weekend.
&&
.AVIATION /00Z Monday THROUGH Friday/... VFR across the TAF sites this evening with VFR to persist through the TAF period. A sct deck around 5kft will develop Monday afternoon, primarily west of the I-77 corridor. Otherwise, high cirrus will gradually stream into the region through the day. Can`t rule out a few isolated rain showers across the southwest portion of the area Monday afternoon and evening, though low confidence precludes vcsh mention.
Winds will favor a south to southeast direction overnight, around 5 knots, before increasing out of the south to south- southwest Monday afternoon, 8 to 10 knots. A lake breeze will impact ERI early Monday afternoon with northwest flow around 8 knots.
Outlook...Non-VFR likely in showers and thunderstorms with a cold front on Tuesday.
&&
.MARINE... Southerly winds at 5-10 knots will continue through the late Monday before turning more southwesterly and increasing to 10-15 knots ahead of a cold front passage on Tuesday. Wave heights will be less than 2 feet through that period. After frontal passage late on Tuesday, winds will shift to be north to northwesterly and increase to 15-25 knots with waves building to 3-6 feet, mainly in the central basin. Winds will decrease to 10-15 knots throughout the day on Wednesday and begin to shift to be more easterly with waves being 1-3 feet as high pressure builds in north of the region to end the week.
