Area Forecast Discussion National Weather Service Binghamton NY 153 AM EDT Mon Sep 28 2020

SYNOPSIS. Ridge over the Atlantic will strengthen with deep southwest return flow developing across the Northeast. Warm and moist air moving in will increase rain chances from tonight and through mid-week with well above average temperatures. Cold front passes on Thursday with much cooler conditions to end the week.

NEAR TERM /THROUGH TODAY/. 130 AM Update..

The forecast remains on track tonight as above-average temperatures hovering in the 60s are not expected to budge much the rest of the night. Lower clouds and light rain/drizzle are spreading across much of the area, and though the Finger lakes and Thruway corridor should be able to stay dry, some scattered mid and higher level clouds are in place for tonight.

310 PM Update .

Pattern will start to really amplify tonight and this will persist through the week. Upper trough digs in across the Midwest, while ridging over the western Atlantic strengthens, with deep southwest return flow developing all the way up the Eastern U.S. and into New England.

Weak low pressure off the Coast of DELMARVA will track inland into Eastern PA late tonight, bringing added low level moisture off the Atlantic. A weak short wave moves along the southwest flow tonight and into Monday and will likely produce a little more widespread rainfall than what we saw last night and through this morning. Also, expecting rain and mostly cloudy conditions through the first half of the day for the Poconos Region and into the eastern Catskills. This wave pushes into New England by tomorrow afternoon and conditions should improve with a lull in the rain through tomorrow night. However, a cold front moves into western NY late Monday night/early Tuesday morning. Rain chances will start to increase by 12Z Tuesday, with latest guidance showing much of our western counties already seeing rain showers out ahead of the front by early Tuesday morning.

SHORT TERM /TONIGHT THROUGH WEDNESDAY/. Overall, a wet short term forecast period is expected. The rain is certainly much needed across the area.

As a deepening low pressure system moves from the Great Lakes northward into Canada, a trailing slow moving cold front will be approaching the area on Tuesday. With a high amplitude trough in place, a southwesterly moist flow will develop ahead of the front. This will bring periods of showers to the area, with perhaps some isolated thunderstorms by the afternoon. By Tuesday night, this front begins to stall east of the area, likely in the vicinity of the Hudson Valley. Then, model guidance continues to indicate another low pressure system forming and riding along the stalled frontal boundary. This would bring additional periods of rain Tuesday night into Wednesday, especially across the Catskills and Poconos.

Locally heavy bands of rainfall will be possible along and ahead of the front with plenty of moisture in place and the region being situated within a favorable jet entrance region. However, with dry antecedent conditions, flooding is not expected to be a concern unless in the unlikely case we receive several inches of rain.

Highs on Tuesday will likely be in the upper 60s to mid 70s, followed by mid to upper 60s on Wednesday.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. 320 PM Update: The long term forecast remains on track and no changes were made with the afternoon forecast package. The previous discussion remains valid.

Previous Discussion:

With the area coming under the broad trof aloft, chances for showers linger into Thursday night as stray shortwave impulses pass through our area. Timing and placement of these features is highly uncertain, thus confidence is there for only chance/scattered PoPs.

A cooling trend will also occur through the extended period. After highs in the 60s Thursday, 50s to lower 60s for highs are expected Friday through the weekend. The cooler thermal profiles along with high pressure nosing in from the Midwest may trigger an enhanced lake response with activity on a west-northwest trajectory, affecting our northern counties in proximity to Lake Ontario with a few showers into Saturday. At this time, Sunday looks to be the driest day of the week, albeit cool.

AVIATION /06Z MONDAY THROUGH FRIDAY/. Low level moisture working back into the region has brought in low clouds, drizzle, and light rain showers across much of the area. IFR restrictions are most likely to set in at KBGM over the next couple of hours, while KAVP continues to see MVFR and IFR restrictions through the night. MVFR restrictions will be possible at KRME, KITH, and KELM later tonight as well, and KELM may even see IFR or lower in patchy fog or drizzle. KSYR is expected to remain under VFR conditions the rest of the night.

Conditions gradually improve to VFR through the morning hours, with KBGM and KAVP holding onto restrictions the longest. Winds turn gusty into the afternoon as a few more breaks in the clouds occur, then lower ceilings start to work back in during the evening with KAVP and KBGM possibly reaching MVFR towards the end of the forecast period. Increasing winds aloft may cause some low level wind shear impacts at KRME, KSYR, KITH, and KELM into the night.

Outlook .

Tuesday through Wednesday . Periods of rain showers and possibly a few thunderstorms bring occasional restrictions to the area.

Wednesday night and Thursday . A chance of rain as a low pressure system moves up along the East Coast; possible restrictions.

Thursday night and Friday . Lake effect clouds and rain showers may bring occasional restrictions; especially the NY terminals.

BGM WATCHES/WARNINGS/ADVISORIES. PA . None. NY . None.
