Area Forecast Discussion National Weather Service Cleveland OH 1229 PM EST Thu Feb 20 2020

SYNOPSIS. High pressure over the northern Plains will build south across the Mid-Mississippi and Ohio Valleys today, then continuing to the southeastern United States through Saturday. Mostly quiet weather is expected through the weekend. Another storm system will bring milder weather and widespread rainfall by early next week.

NEAR TERM /THROUGH FRIDAY/. No big changes for the afternoon.

Previous discussion . The weather is relatively quiet and uneventful this morning. We have some scattered to broken high cirrus moving across the Ohio Valley Region. The center of a Canadian high pressure system was currently centered over the Upper Midwest region this morning. This high pressure system will continue to bring northwesterly winds and cold advection today across the eastern Great Lakes. Temperatures will struggle today and only manage to reach the middle to upper 20s this afternoon. The center of the high will move down to the Mid- Mississippi Valley region by Friday morning.

The only weather concern for the next 36 hours will be the potential for some light lake effect snow showers for the primary Snowbelt region today through this evening. Scattered lake effect clouds and some flurries were already developing this morning for areas of far northeastern Ohio and northwestern Pennsylvania. Colder air aloft at 850 mb will continue to move in today with 850 mb temperatures falling down to -15C to -18c by mid afternoon. While not the best setup for organized lake effect snow bands, there will be some scattered lake effect snow showers by late morning through early evening for the higher terrain of Ashtabula County into Erie County and Crawford County PA. We could see a dusting to 1 inch of snowfall later today. Where skies are clear tonight and away from the lakeshore, low temperatures will be the coldest this week with temps down into the lower and middle teens. Southwesterly winds 10 to 20 mph will return on Friday on the back side of the exiting high pressure system. Afternoon temperatures will start the rebound process and make it to the middle and upper 30s which is just about typical for this time of year.

SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/. The short term forecast period remains very quiet, as previously advertised. High pressure to the southwest of the region on Friday night will continue to push east towards the Tennessee Valley on Saturday and then off the Southeast U.S. Coast on Sunday. This high is supported by a strong upper ridge, allowing for strong subsidence over the region, and in turn, dry weather. The main forecast challenge with this forecast period are the temperatures. The recovery will have begun on Friday, but as this high pressure pivots south and southeast of the region, warm air will surge into the region. Have continued to push temperatures warmer through the period with 40s across the area on Saturday and upper 40s to lower 50s on Sunday. Low pressure will enter from the southwest on Sunday night into Monday, and much of the wet weather will be for the long term forecast period (See Below), but have a chance of rain entering the western part of Ohio after Midnight on Sunday night.

LONG TERM /MONDAY THROUGH WEDNESDAY/. The long term forecast period will be quite the change from the quiet weather from the weekend. A shortwave trough will enter the Central Plains on Monday, supporting a low pressure system that will move through the Great Lakes region on Monday into Tuesday. This will bring wet weather back to the region to start the week and have likely PoPs at this time for portions of Monday. Have much of the precipitation type as rain as warm air still lingers over the region and high temperatures are expected to be in the 40s for much of the area. The low passes through the region on Tuesday and its associated cold front will clear by Tuesday afternoon, bringing temperatures down closer to normal. For Wednesday and beyond, the extended guidance has finally settled on the colder solution, featuring a sort of clipper system entering from the northwest. This system will bring the chance for some snow on Wednesday and beyond, as temperatures are back towards normal in the upper 30s for highs and mid 20s for lows.

AVIATION /18Z Thursday THROUGH Tuesday/. High pressure will continue to build into the region through the overnight hours and into Friday. Through the afternoon however, a cold northwest flow across Lake Erie will continue the threat of MVFR cigs and visibilities in scattered snow showers for northeast Ohio and northwest PA. From late afternoon into the evening expect dry air to overwhelm and lake induced forcing and bring the threat of snow showers to an end. Expect VFR conditions overnight and Friday.

OUTLOOK. Non-VFR possible with widespread snow and/or rain Sunday night into Monday morning and with rain Monday afternoon.

MARINE. High pressure over the Red River Valley will be the main factor for the marine weather through Sunday. This area of high pressure will expand over the Great Lakes today as it makes its slow journey from the northern Plains to the Southeast United States for this weekend. For today, this area of high pressure will remain centered northwest of Lake Erie, allowing for northwest flow over the lake, which has been losing strength with time. As this high pivots southwest of the lake on Friday into Saturday, flow will shift around more to the southwest. A low pressure system will be moving well north of the lake in Canada, and the resulting pressure gradient between this low to the north and high to the southwest will allow for winds to be somewhat strong, perhaps up to 20-25 knots on Friday into Saturday. This persistent flow will also allow for waves to build over the eastern half of the lake. At this point, a Small Craft Advisory seems likely for some period of Friday into Saturday. High pressure will move off the Southeast US coast on Sunday and flow will become lighter and more southerly, ending any hazardous marine weather. Low pressure entering the Central Plains on Sunday night and moving towards the Great Lakes region will allow for offshore, southeast flow over the lake on Monday.
