Area Forecast Discussion National Weather Service Pittsburgh PA 656 AM EST Thu Feb 20 2020

SYNOPSIS. Outside of isolated flurries today, high pressure will maintain dry conditions, with moderating temperature through the weekend.

NEAR TERM /THROUGH TONIGHT/.

Morning Update: No major changes have been made in this forecast period.

Previous Discussion: Dry weather, as defined by non- measurable precipitation, is expected to continue today despite the encroachment of an upper trough/associated reinforcing cold front. Model world continues to dispute the eventual moisture supply available for precipitation over the region with GFS remaining the more aggressive. Either way, sufficient low level lapse rates into a shallow dendritic growth, with frontal lift and forcing for ascent via the upper trough, albeit weak, are enough to maintain a slight chance of some light snow/flurries.

Early timing of the reinforcing cold front should hold high temperature about 10 degrees under the averages.

SHORT TERM /FRIDAY THROUGH SUNDAY/. Broad high pressure will maintain dry weather through Sunday with gradual temperature moderation. No real change was made to the weekend forecast.

LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/. Precipitation chance is forecast to increase again by Monday as southern stream low pressure emerges from the Plains and digs up the Ohio Valley as it weakens. With colder air locked northward via the northern stream of the jet, and with warm advection on the van of the low, precipitation with that event should primarily be rain.

Models agree that an amplifying, and encroaching upper trough is likely to continue precipitation chances into midweek and then bring colder weather to the region.

AVIATION /12Z THURSDAY THROUGH MONDAY/. Marginal MVFR cigs are possible across FKL/DUJ later this morning and early afternoon with a crossing shortwave. Otherwise, VFR is expected through the period with high pressure. Isolated flurries are also possible today with the shortwave, but should remain light enough such that conditions remain VFR.

Outlook. Restrictions will be possible late Sunday with the approach of low pressure.

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.
