area forecast discussion... Updated
national weather service pittsburgh pa
353 pm edt Mon mar 25 2019

Synopsis
Rain will be exiting to the southeast this evening. High
pressure brings dry and cool weather Tuesday, with a warming
trend thereafter.

Near term until 6 am Tuesday morning
4pm update... Made changes to the late afternoon evening pops
using radar trends and latest hires model guidance. Rest of the
forecast in good shape.

Previous discussion...

a rapid end to the precipitation will occur late this
afternoon and evening as the wave exits and the shield shifts
sewd.

Given the persistent cloud cover, temperature will struggle to
rise, with maxima expected to reach the mid-upper 40s in most
areas. Cooler air will invade tonight, changing any lingering
rain showers over to snow showers at the highest elevations.

With the short window, limited lift and warmer ground, any
accumulation is expected to be trivial.

Rapid clearing tonight will enable temperature to drop into the
20s by morning.

Short term 6 am Tuesday morning through Wednesday night
High pressure will dominate Tue and wed, with abundant sunshine
both days. Temperature will continue to run below seasonal
average through Tue night, but will recover toward average on
wed as return flow develops in the wake of the departing sfc high
pressure.

Long term Thursday through Monday
A cold front will sag swd on Thu into the SRN great lakes region
as a strong jet moves thru a broad trough in ERN canada. The
front will slow its progress, however, as it becomes oriented
parallel to the mean flow.

The presence of the stalled boundary and increasing sly flow
ahead of a SRN plains trough will lead to increasing moisture
and the potential for occasional light rain for much of the
latter periods of the forecast.

Pops were increased a bit from prior forecasts during this
timeframe, but rain will not be constant. The greatest chance
for rain will come Sat afternoon thru Sun morning, as the srn
wave is absorbed into a stronger wave advancing from the nrn
plains.

For much of the latter half of the week, temperature will be
near to above seasonal average. But after this strong wave
progresses ewd, cooler air will be driven swd for a short
tenure to start next week.

Aviation 20z Monday through Saturday
MVFR ifr restriction withing the rain shield. North of the rain,
conditions improve quickly back toVFR. All rain should be out
of the TAF sites around 00z, and clearing sky will allow for a
return toVFR at all locations.

Outlook
Vfr expected through midweek. Restrictions possibilities return
late week with a quasi-stationary front.

Pbz watches warnings advisories
Md... None.

Oh... None.

Pa... None.

Wv... None.

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