Area Forecast Discussion National Weather Service Binghamton NY 628 AM EDT Sat Jun 22 2024

Hot and humid conditions will continue through the weekend, with scattered thunderstorms returning today, with even more on Sunday, as a cold front sweeps through the area. Some stronger storms may produce damaging winds and torrential rainfall. Heat and humidity will subside Monday and Tuesday behind the front.
Showers and thunderstorms look to return on Wednesday.

414 AM Update...

A few convective showers have started developing over Oneida County north of a stalled out frontal boundary. Some additional development is possible over the next couple hours, and they may expand westward a bit before heading off to the east after sunrise.

Additional showers and thunderstorms are expected to develop by early afternoon, likely starting in the Finger Lakes region as the front sags south. Later in the afternoon and into the evening hours, the focus for thunderstorms looks to shift south and east away from the boundary in the more moist and unstable airmass across the Twin Tiers and NEPA. Expect like the past couple of days thunderstorm initiation will be triggered off outflow boundaries, and we'll likely have a few indistinct differential heating boundaries in the unstable airmass, the linger effects of rain-soaked areas from yesterday. The end result will just be similar to the past couple days, scattered to numerous pop-and-drop thunderstorms. Deep layer shear of 25 to 30 knots is a little healthier than the past few days, and this may result in a few more strong to severe storms with downburst winds being the main threat.

Activity will once again follow a diurnal trend, with showers and thunderstorms diminishing overnight. Valley fog is likely in the more sheltered valleys, as a stronger pressure gradient should keep a little more wind going through the night.

It will remain hot and humid today, especially south of the stalled out front, where Heat Advisory criteria looks to again be met across the southern Finger Lakes, Twin Tiers, and NEPA.

A cold front will push into the area on Sunday along with a more significant shortwave trough, and attendant stronger mid and low-level flow. Bulk shear around 40 knots will be a significant uptick, but the timing of the shortwave trough is a little on the early side, and instability may not build up quite as much as it could otherwise. SPC Slight Risk covers the whole CWA, but areas E and SE of a SYR-ELM line may be slightly more favored for severe thunderstorms due to timing.

Kept the Heat Advisory as-is for Sunday, though if the earlier cold front passage holds, we may be able to drop the western- most counties.

345 AM Update...

The positively tilted trough will continue to influence the weather for our CWA through Sunday night. Lingering showers will remain behind the cold front as the upper level trough lags behind the surface cold front and a mid- level shortwave ripples through the overall trough pattern during the overnight hours. To help boost precipitation chances, the upper level trough axis will swing across our northern counties later in the night. Showers and isolated thunder chances will be the highest (40-60%) north of the Southern Tier during the overnight hours. We will finally get a reprieve of hot overnight temperatures as lows will fall into the upper 50s to mid 60s. Dewpoints will fall into in the low 60s so it will still feel a little sticky out, but should be noticeably different than what we have been dealing with.

Guidance remains a little unsure on how much the trough will be positively tilted and how fast it moves through the region on Monday, so precipitation chances were extended into the afternoon hours. Temperatures will rise into the low to mid 70s across much of the area thanks to northerly flow that will push a Canadian airmass into the region. With this airmass comes much less humid air, with dewpoints in the mid to upper 50s. Another ridge will build in from the west during the evening hours, which will clear us out and allow radiational cooling to drop overnight lows into the 50s.

Tuesday will see the ridge axis slide east of us once again, bringing SW flow and warm temperatures back to the region. Highs will climb into the 80s, with higher elevations in the low 80s and valleys in the upper 80s. Luckily, dewpoints should remain in the upper 50s during the hottest part of the day so we should miss out on sweltering heat we experienced this past week. This ridge will be transient and not nearly as strong as the one we are currently under. The next trough will move into the Great Lakes Tuesday night, allowing for a slight chance of rain showers over the Finger Lakes. Overnight lows will be in the 60s.

350 AM Update...

Active weather returns Wednesday into Thursday morning as a broad trough pattern returns to the area. A series of shortwaves will move through during the morning and early afternoon hours, generating scattered showers across the area. Guidance shows a cold front moving in sometime later in the afternoon to late evening hours. The timing of this will greatly determine the severe weather chances for the day with an afternoon arrival having the highest chance. WPC also has us in a marginal chance for excessive rainfall Wed into Thurs morning, which is backed up by the chance for multiple periods of heavy rainfall. We will have to keep a close eye on this setup.

High pressure fills in behind the cold front, bringing a nice end to the work week.

Scattered showers are moving across portions of north central NY early this morning, and with MVFR ceilings expected to last a few hours at RME. Otherwise, VFR will prevail elsewhere except for the odd MVFR visby in heavier showers.

Valley fog will lift between 12Z and 13Z at ELM. The Wyoming Valley is fogged in below AVP at the time of this discussion.
Expect fog/mist to spread up into the hills with a bit of mixing this morning, bringing restrictions to AVP for a couple hours.

Shower activity this morning will be transient, but showers and thunderstorms are expected to redevelop early in the afternoon.
Timing remains fairly uncertain beyond the usual diurnal trend being favored. Thunder is most likely at ITH, ELM and especially BGM and AVP this afternoon and evening. Still did not want to blanket too large an area over too large a time frame with thunder, so just mentioned VCTS at BGM and AVP for the time being, with no TEMPO groups.

Showers and thunderstorms will diminish during the evening hours. Areas of fog are likely, especially where it rains, but a tighter pressure gradient may reduce potential outside of the most sheltered valleys. Scattered mid clouds will also be mitigating factor as well.


Sunday Morning...Restrictions possible in valley fog, especially ELM.

Sunday Afternoon into Monday Morning...Widespread showers and thunderstorms Sunday with associated restrictions, mainly to visibility. Lingering restrictions possible in showers early Monday.

Monday afternoon through Wednesday...VFR conditions likely.
