Area Forecast Discussion National Weather Service Pittsburgh PA 1122 PM EST Thu Dec 12 2019

SYNOPSIS. Precipitation chances return Friday with a weak disturbance. Widespread rain is expected Friday night and Saturday with crossing low pressure.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. Dry weather should continue tonight under a sfc ridge of high pressure. Clouds are expected to stream over the region in warm advection ahead of an approaching shortwave in SW flow aloft. Lows should be near seasonable levels.

SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY/. Warm, moist advection, from continued SW flow, and an advancing shortwave into the Ohio River Valley will slowly increase cloud cover early tomorrow morning. With high pressure focused over Novia Scotia, cold air will be reinforced east of the ridges. With SE upsloping flow, dynamic cooling will keep Garrett/Tucker County below freezing. As a result, a Winter Weather Advisory has been issued for freezing rain late Friday morning through mid-day. Outside of freezing rain, rainfall amounts near Pittsburgh will average 0.50 inches; 0.75 to 1.00 inches east of I-79.

With advancing cold air from the northwest, rain will transition to a mix of rain/snow late Saturday.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/. Snow/rain mix will continue Saturday night before switching over to all snow Sunday morning with cold advection in the wake of the low. Snow accumulation is expected to be light and mainly focused in the ridges due to post-frontal upsloping.

Expect temperatures to remain near seasonal average Sunday through Tuesday, depending on the track of a new sfc low. Colder temperatures should return mid-week as Artic air crosses the Great Lakes.

AVIATION /04Z FRIDAY THROUGH TUESDAY/. VFR conditions are expected through the forecast period. High clouds are expected through most of tonight, with lowering/thickening clouds after 12Z Friday as moisture increases ahead of an approaching shortwave. Light rain will arrive after that time as well with condition deterioration as eve apchs.

Outlook. Restrictions are likely this weekend with crossing low pressure.

PBZ WATCHES/WARNINGS/ADVISORIES. MD . Winter Weather Advisory from 7 AM to 3 PM EST Friday for MDZ001. OH . None. PA . None. WV . Winter Weather Advisory from 7 AM to 3 PM EST Friday for WVZ514.

Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
