. 12z Aviation Forecast Update .

SYNOPSIS. Low pressure over the Great Lakes region will move east towards Quebec today. This upper level trough will weaken and move off the East Coast with a ridge of high pressure expanding south out of Canada and remain in control for much of the week.

NEAR TERM /THROUGH TUESDAY/. A large and nearly vertically stacked upper level low and surface low pressure system is currently located near the Upper Great Lakes region this morning. This weather system will continue a slow track eastward towards Quebec today and tonight. Colder air aloft associated with the upper level system and trough is causing widespread cloud cover wrapping around the system. Some of the cloud cover is also associated with instability and moisture from the Great Lakes as well. We will continue to see cool and cloudy conditions today across the entire area with blustery winds from time to time and a few passing sprinkles or light showers. The chances for light and measurable rainfall will be confined to more of the Snowbelt areas later today through tonight with a little lake effect rain showers coming off Lake Erie later today. Temperatures today will hold steady in the middle 40s for much of the day but when winds 15 to 20 mph, it will make it feel more like the 30s with the wind chills.

Tonight, we will continue to see clouds and scattered lake effect rain showers mainly across the Snowbelt region. Surface temperatures and just above the ground may cool down enough for some of the rain showers to mix with or change over to some wet snow flakes late this evening and overnight before the moisture moves out by early Tuesday morning. Overnight temperatures should safely stay above freezing for the most part. We do not expect any impacts from rain/snow showers in the Snowbelt region. The flow becomes more northerly or northeasterly by Tuesday which will continue to see widespread cloudiness and maybe a spotty sprinkle. With a flow off the cool waters of the lake, temperatures will stay in the middle to upper 40s Tuesday.

SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/. Upper level troughiness will begin to exit to the east early in the period as the overall upper level pattern shifts. An upper level ridge will build gradually east toward the area and amplify with time through this forecast period. The ridge is expected to remain just west of the region by Thursday night allowing a vigorous shortwave trough to move south through the eastern Great Lakes region. A surface trough will extend northwest from low pressure that will race east in the southern stream early in the period. This trough will move east of the area by Wednesday as surface high pressure builds east into Ontario, Canada and the western Great Lakes. The surface trough could bring a slight chance of showers over the eastern portions of the forecast area Tuesday night into Wednesday. Otherwise, as high builds east, fair weather will become the rule across the region. Overnight low temperatures are expected to remain in the 30s through the period but a slight warming trend from the 40s for highs Wednesday to the lower and middle 50s west to middle 40s east by Thursday.

LONG TERM /FRIDAY THROUGH SUNDAY/. An upper level ridge will move east across the local area during this period but weaken with time. This ridge will become absorbed into a much broader upper level ridge that is expected to amplify over much of the United States by Sunday. Surface high pressure will lift northeast of the area Friday and Friday night while a cold front approaches the region. The cold front is expected to move east across the forecast area late Saturday night followed by high pressure possibly late Sunday. The front slows in forward motion an d becomes nearly stationary. A swath of moisture associated with the front will linger over the local area and bring with it a chance to slight chance for some shower activity. Moderating temperatures will persist through the end of the week into the weekend with highs in the upper 50s to lower 60s and lows in the 40s.

AVIATION /12Z Monday THROUGH Friday/. The main aviation concerns with this forecast update will be the lowering of ceilings to low end MVFR with some IFR at times possible for CAK or YNG. A vertically stacked low pressure system will slowly move away from the Great Lakes region towards Quebec with wrap around clouds and spotty showers. MVFR ceilings linger through much of the TAF period. Westerly winds will remain elevated and gusty 10 to 15 knots with gusts up to 25 knots during the day. The gusty winds will finally relax somewhat by this evening and overnight.

OUTLOOK. Non-VFR conditions possible Tuesday through Wednesday with low ceilings and spotty rain showers.

MARINE. A small craft advisory remains in effect as northwest winds persist through today at 15 to 25 knots across the lake. Winds are expected to diminish tonight to 10 to 15 knots and remain light and variable through Friday. No other headlines are expected during this forecast period once the small craft advisory is dropped later today from west to east.

CLE WATCHES/WARNINGS/ADVISORIES. OH . None. PA . None. MARINE . Small Craft Advisory until 10 PM EDT this evening for LEZ147>149. Small Craft Advisory until 10 AM EDT this morning for LEZ142>144. Small Craft Advisory until 4 PM EDT this afternoon for LEZ145- 146.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
