Area Forecast Discussion National Weather Service Cleveland OH 1209 AM EST Wed Jan 22 2020

. 06z Aviation TAF and Near Term Forecast Update .

SYNOPSIS. Unsettled weather returns to the area Friday morning and continues through the weekend. Near normal temperatures will be present across the area tomorrow with slightly above normal temperatures through the rest of the forecast.

NEAR TERM /THROUGH WEDNESDAY NIGHT/. Update . Some more minor adjustments to sky cover and low temperatures with the mid evening update. Temps starting to plummet in some areas where BL decoupling has occurred. These are the primarily cools spots in the southeast part of the forecast area that could dip into the single digits. For the most part elsewhere, light southerly winds should keep things mixed enough to curtail dramatic radiational cooling.

Original discussion . Surface high pressure will prevail over northern Ohio and NW PA through Wednesday night. This will spell near normal temperatures and dry conditions for the forecast area. High temperatures will warm into the mid 30s, with overnight low temperatures bottoming out in the mid teens tonight and the mid 20s late Wednesday night. Otherwise, little to report from the near term forecast.

SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/. After a few days of quiet weather, another system will take aim across the region by the end of the week into the weekend. Temperatures look to be above average again on Thursday with highs in the low to mid 40s. As high pressure moves off the East Coast Thursday, a low pressure system will develop across the Missouri Valley. Models are in good agreement with timing and location that this low will move northeastwards, with precipitation reaching the Ohio Valley by Friday morning and late afternoon. Precipitation will stream in from the southwest, possibly beginning as snow or a wintry mix for a few hours Friday morning with temperatures at or just below freezing. However, with warm air aloft already in place, precipitation should quickly changeover to rain as WAA will warm surface temperatures into the low to mid 40s by early Friday afternoon across the area. Temperatures will remain above average Friday night as rain is expected to continue across the area.

LONG TERM /SATURDAY THROUGH TUESDAY/. Temperatures look to stay above average through the long term period. By Saturday, models indicate low pressure will be directly over the Ohio Valley, before moving east and transitioning to a coastal low off the New England Coast. Temperatures look to remain normal to slightly above normal throughout the day Saturday in the mid 30s as the low sits overhead, limiting the potential for any significant cold air advection. This will likely result in more of a rain/snow mix rather than precipitation type being all snow. Total precipitation amounts look to be around a quarter to a half inch. As the low moves east of the Ohio Valley by Saturday night, cooler air will attempt to make its way across the area, but lows will stay above average in the low 30s. However, colder temperatures aloft should allow for precipitation to become all snow by Sunday morning, although not expecting any significant accumulations. Lake effect snow will be possible in NE OH and NW OH throughout the day Sunday into Monday, but instability will be marginal at best with 850 temps bottoming out around -6C. Surface temperatures will hover around or just above freezing as well, which will limit any additional snow accumulation. By Tuesday, warm air advection increases once again ahead of the next system which is expected to develop in the southern Plains.

AVIATION /06Z Wednesday THROUGH Sunday/. The conditions will be VFR and quiet weather for pilots flying in and out of northern Ohio and northwest Pennsylvania for the next 24 to 30 hours. Some high level cirrus clouds will increase but no impacts expected. Winds will be southerly about 5 to 10 knots.

OUTLOOK. Non-VFR possible Thursday night into Friday in light snow.

MARINE. Have opted not to go with a small craft advisory for overnight tonight as winds are marginal at best and wind direction is not as favorable for higher waves along the nearshore in NE OH. Otherwise, winds will be generally light and variable across the lake through Friday. Easterly winds will increase by the end of the week across the lake as low pressure approaches, but look to remain below criteria for now.

CLE WATCHES/WARNINGS/ADVISORIES. OH . None. PA . None. MARINE . None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
