Area Forecast Discussion . UPDATED National Weather Service Pittsburgh PA 100 AM EDT Mon Sep 20 2021

SYNOPSIS. Dry and warm weather is expected today under a ridge of high pressure. Rain chances will increase through mid week with the approach of a cold front.

NEAR TERM /THROUGH TODAY/. No changes to the overnight period.

A developing trough will deepen across the central Rockies today, causing a corresponding amplification of the eastern CONUS ridge. Increasingly warm, moist southerly flow aloft will develop over the region as we rest under the impressive ridge. High cirrus clouds will cross the region today as the ridge drifts eastward. Temperatures will remain above normal.

SHORT TERM /TONIGHT THROUGH WEDNESDAY/. The trough will drop into the central plains Tuesday and strengthen moist southwest flow over the Ohio River Valley and shunt the sfc high/ridge farther east. A series of fast moving shortwaves, within the SW flow, will increase shower chances, particularly over the western half of the forecast area.

Showers will spread eastward Tuesday night through Wednesday as the upper trough closes off and becomes negatively tilted with a notable surface cold front nearing the region. The lack of instability, due to warm air aloft and lack of sfc heating, will reduce the likelihood of thunderstorms, but a deep column of moisture should allow for warm-rain processes that will promote higher rainfall totals.

There remains some uncertainty in the finer details due to varying model positioning, timing of closure, and degree of negatively tilting of the upper low as well as the positioning/strength of the sfc low. These factors will determine how quickly rain advances east and the locations of the axis of heaviest rainfall.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. The closed upper low will drift northward over the eastern Great Lakes Thursday as the surface cold front pushes across the region. Cold advection behind the front, and dry air wrapping around the upper low, will dissipate lingering light rain showers, with dry conditions developing Thursday night. Look for temperatures to be 5 to 10 degrees below seasonal averages.

Surface high pressure, under longwave troughing, will leave the area dry Friday with temperatures a few degrees below seasonal average. Eastern U.S. troughing will likely continue into the weekend with additional shortwaves crossing the region, leading to periodic precipitation chances and slightly below average temperature.

AVIATION /05Z MONDAY THROUGH FRIDAY/. VFR is expected through the TAF period under a ridge of high pressure. Wind speed is expected to be sufficient to preclude significant fog development overnight. Mid/high lvl clouds are expected to increase through Monday in moist advection in S-SW flow aloft ahead of an approaching trough.

Outlook. Restrictions are possible Tue, before becoming widespread in rain Wed/Wed night with approaching low pressure. Restrictions will remain psbl Thu/Fri under an upper trough.

PBZ WATCHES/WARNINGS/ADVISORIES. PA . None. OH . None. WV . None.
