000 FXUS61 KPBZ 141624 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 1124 AM EST Sun Jan 14 2018 .SYNOPSIS...
-- Changed Discussion --
High pressure will maintain dry but cold weather today. Low pressure will bring light snow to the region Monday and Tuesday.
-- End Changed Discussion --
&& .NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
Very little in the way of clouds across the region with surface high pressure in place. PLenty of insolation and minor height rises will allow for temperatures to moderate a bit today. Adjusted highs slightly to account for this. Otherwise, quiet conditions will continue through tonight. Despite some warming aloft, lows should still fall back into the single digits, though it will not be as cold as last night.

&& .SHORT TERM /MONDAY THROUGH TUESDAY/...
-- Changed Discussion --
Next system to bring the chance for light snow Monday and Monday night. Models still having timing issues, particularly when the snow will begin. It does appear that models are in agreement that snow will taper off from north to south Monday night, as much drier air aloft will invade the snow growth zone. Kept likely to categorical PoPs for much of the region, with PoPs decreasing from northwest to southeast late Monday night. Behind this system, another shot of cold air. Expect little to no lake enhancement snow showers in the colder air, as winds aloft remain southwest through most of Tuesday, only late in the day, do they veer to the west, but by this time they rapidly weaken.

&& .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... Upper trough will remain in place through much of the period, with more zonal flow expected by the end of the week, returning seasonable or slightly warmer values. Stayed close to the superblend for PoPs through this time frame, with no large systems expected. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... VFR conditions and light winds expected through the TAF period under high pressure. .OUTLOOK... The next chance of widespread restrictions will arrive on Monday with another round of snow. && .PBZ WATCHES/WARNINGS/ADVISORIES...
