Area Forecast Discussion . UPDATED National Weather Service Pittsburgh PA 1208 PM EST Tue Dec 10 2019
SYNOPSIS. Rain will linger into the afternoon and overnight south and east of Pittsburgh. Minor snow accumulations are expected, mostly limited to the ridges and higher elevations. Dry and cooler conditions are expected through Thursday before a warm-up this weekend.
NEAR TERM /THROUGH TONIGHT/. A strong mid-level jet remains oriented SW-NE across the Ohio Valley ahead of a broad trough in the north-central CONUS, while a sfc front makes steady progress across the region. Temperature has dropped ~10F with its passage over the last several hours. Widespread rain continues in association with the jet/warm advection regime ahead of the front.
The cold air is expected to lag the precipitation for much of the day as the entire system translates ewd. However, by mid-afternoon, the cold air may overlap sufficiently with the precipitation to effect a transition to snow in the sern quadrant of the forecast area. Although impactful accumulation is not expected, the greatest accumulation will be in the ridges, where snow ratios will be more efficient as a result of better overlap of moisture with the DGZ.
A surge of much colder air over MI is making slow progress across Lake Erie this morning, but lake-effect showers will develop this afternoon and spread ewd as the upper trough advances. These showers may move across the far-nrn zones late today/tonight, with occasional brief bursts of snow possible.
As cold advection continues, temperature will maintain its fall through tonight, with minima reaching the low-mid 20s late tonight despite sustained cloud cover.
SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/. Colder and drier air will arrive on Wed as high pressure begins to build across the region in the wake of the exiting upper trough and downstream of a wrn-CONUS ridge. Amid clearing sky, light wind and building sfc high pressure, temperature seems likely to fall considerably more on Wed night, potentially into the mid-teens in many areas.
Flow aloft will flatten on Thu, aiding in the progressive exit of sfc high pressure and an eventual development of sly return flow. Although Wed will be cold and potentially peaking in the upper 20s, Thu will see a steady warm-up into the 30s (albeit still below seasonal average) amid increasing sunshine.
LONG TERM /FRIDAY THROUGH MONDAY/. There remains higher confidence in the evolution of the upper-air pattern late in the week, as an upper trough amplifies in the central CONUS. This pattern will support increasing swly flow and strong warm advection for the Ohio Valley, leading to seasonably warm days and increasing chances for rain, particularly over the weekend.
AVIATION /18Z TUESDAY THROUGH SUNDAY/. An incoming shortwave trough will bring a return of MVFR cigs areawide while shunting the shield of stratiform rain south and east of the region today. Residual precipitation will turn over to snow for areas along the eastern ridges by this aftn, but snow is not expected to be heavy with little accumulation given intrusion of drier air and waning upper-level support.
The crossing of the upper trough tonight into Wednesday morning will further push the dry slot over the region and eliminate restrictions west to east. Building sfc high pressure should keep most areas VFR Wednesday.
Outlook. Restrictions are likely with the next low pressure system this weekend.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
