000 FXUS61 KPBZ 240414 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 1214 AM EDT Sat Jun 24 2017 .SYNOPSIS...

&& .NEAR TERM /THROUGH TODAY/...
-- Changed Discussion --
Light to moderate rainfall will continue to shift eastward this morning following the low. Much drier air evident on the low- level water vapor imagery to our west is quickly eroding the western edge of the rain as the low departs. The result will be an end to any appreciable rainfall by daybreak, ending in our southeast counties last. The Flash Flood Watch will be allowed to expire at 2am, as scheduled. The cold front will move through later this morning, leaving in its wake lower dewpoints and clearing skies. Despite drying through the column, some residual moisture will be present in the mid-levels today. This will allow afternoon cu to develop as cold air advection commences. Northern zones near and north of I-80 could see an afternoon shower develop as a weak upper-level shortwave passes through the broader trough. Precipitation amounts with this activity should be negligible. Increasing sunshine will compete against the cold air advection; the result will be high temperatures right around the average.

&& .SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/...
-- Changed Discussion --
Dry weather continues for the second half of the weekend despite less sunshine. Yet another passing short wave will bring clouds and given its stronger than the one Saturday isolated showers are possible north of the I-76 corridor in the late afternoon / early evening hours Sunday. Mid level heights continue to fall as we kick off a new work week. Most of the energy will reside along the lakes, so precip chances are small over northern WV and western MD when compared to northwest PA. Any shower will be brief. The bigger story is the spring like feel as daytime high temps do not leave the 60s Monday! This will be almost 15 degrees below normal.
