Area Forecast Discussion National Weather Service Pittsburgh PA 538 AM EDT Mon Oct 26 2020

SYNOPSIS. Weak crossing disturbances will maintain light rain chances through Tuesday. Widespread rain is likely by Thursday with low pressure.

NEAR TERM /UNTIL 6 PM THIS EVENING/. A crossing shortwave embedded in SW flow aloft, jet support, and a weak sfc trough should maintain sufficient ascent for areas of light rain today. A stratus layer should also result in cloudy skies.

High temperatures are expected to be around 5 degrees below average with the cloud cover and patchy light rain.

SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/. Continued ascent with weak shortwave support embedded in SW flow aloft and a northern stream jet should maintain the light rain chances through tonight. A flattening shortwave trough is progged to cross the Great Lakes and Upper Ohio Valley region Tuesday and Tuesday evening, with the light rain chances ending with its passage. Dry weather is then expected later Tuesday night and Wednesday as sfc high pressure briefly builds across the Upper Ohio Valley region.

A closed upper low is expected to track across the Srn Plains Wednesday night. Remnant tropical moisture is progged to advance through the SW flow aloft ahead of the low, approaching the Ohio Valley region late Wednesday night. This should result in increasing ascent and moist advection, and escalating rain chances, across the region. Seasonably cool temperatures are expected to continue through the period.

LONG TERM /THURSDAY THROUGH SUNDAY/. The upper low is expected to open and phase with a northern stream trough Thursday and Thursday night, as both systems cross the Great Lakes and Ohio Valley regions. This, combined with the remnant tropical moisture, should maintain the likelihood of widespread rain across the region.

Rain chances should diminish through the day Friday as the trough exits ridging begins to build across the region. Dry weather should continue Saturday under the ridge before a trough advances out of the Midwest Sunday. Model ensembles depict a weaker trough than operational models, so only included an increase in clouds Sunday at this time. Temperatures are expected to average near to below seasonable levels through the period.

AVIATION /10Z MONDAY THROUGH FRIDAY/. Low MVFR, with patchy IFR conditions, are expected through the TAF period with low lvl moisture in place in the vicinity of a crossing sfc trough and associated shortwave aloft. Patchy light rain and is also possible with the combined ascent and moisture in place.

Light SE wind should gradually veer to the NW as the sfc trough crosses.

Outlook. Restriction chances continue through Tue, and again Thu/Fri, with the next low pressure systems.

PBZ WATCHES/WARNINGS/ADVISORIES. MD . None. OH . None. PA . None. WV . None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
