SYNOPSIS. Quiet weather will continue today. A low pressure system will return rain to the area Friday night and Saturday.
NEAR TERM /THROUGH TONIGHT/.
Quiet and dry conditions will continue under high pressure. Mid and upper-level clouds will stream through our region from the SW as shortwave forms in the Central Plains.
SHORT TERM /FRIDAY 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 WEDNESDAY/.
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 /18Z THURSDAY 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 precipitation will arrive after that time as well, with freezing rain possible along the ridges and a rain/snow mix to the west.
Outlook. Restrictions are likely this weekend with crossing low pressure.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
