AREA FORECAST DISCUSSION National Weather Service Albany NY 735 PM EDT Tue May 7 2024
SYNOPSIS
After a warm and dry day today, there will be several chances for rain through this weekend. A few thunderstorms are possible late tonight and tomorrow, and a couple storms tomorrow afternoon could be on the stronger side. After another warm day tomorrow, temperatures trend cooler for the end of the week.
NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/
As of 735 PM EDT...Surface high pressure continues to be located over the Northeast. Meanwhile, a warm front is located south of the region over the Ohio Valley and northern mid Atlantic States. This warm front will be trying to head towards the area for later tonight.
IR satellite imagery and surface observations continue to show fairly clear skies over the area, with just some patchy cirrus around. Based on the latest model trends, dry weather continues through the first half of tonight. With clear skies and light winds, temperatures should drop off fairly quickly this evening after sunset, but will level off after midnight as cloud cover increases and winds pick up. Overnight lows will likely end up in the 40s to 50s. The upper ridge weakens as it moves overhead tonight, and an upper low tracks into the Great Lakes. This feature will be associated with an area of low pressure at the surface, and will be responsible for quite a bit of convection upstream overnight. As the system's warm front approaches our region late tonight, this convection will move into our area between 7-10z from west to east, bringing chances for showers and possibly a few rumbles of thunder with forecast soundings showing a few hundred joules of elevated cape. However, with a low-level inversion in place, the convection should remain elevated and thus severe weather does not look to be a concern overnight tonight despite increasing shear as the low-level jet strengthens.
SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/
Forecast for tomorrow remains complicated, with a chance for some stronger storms...The day begins with the surface warm front continuing to lift northwards through our region. There will likely be lingering convection around to start the day associated with this warm front, especially north of I-90. Then, later in the afternoon, the upper low will open up as it tracks through upstate NY. The system's cold front will track through tomorrow evening, pre-frontal trough will track through the region tomorrow afternoon.
Behind the warm front, we should get into the warm sector with temperatures climbing well into the 70s, especially for areas along and south of I-90. With steep mid-level lapse rates in excess of 7C/km, this will lead to SBCAPE values approaching 1000 J/kg, with some pockets of locally higher values possible in the Mid Hudson Valley and western New England. Deep-layer shear also increased to 60-70 kts. While this parameter space is fairly impressive for our area, the best upper forcing will remain to the north and will not overlap with the best instability/shear. The best chance for any stronger storms appears to be across the Mid Hudson Valley, western MA, and western CT with any storms that develop with/ahead of the pre- frontal trough. Therefore, it looks like a fairly narrow window from very late morning through mid-afternoon where storms are possible. With mean flow perpendicular to the low-level forcing, and weak upper forcing, some discrete storms could develop in these areas ahead of the pre-frontal trough. The severe threat is conditional on convection initiating, but if any storms do develop the primary threats look to be gusty winds with steepening low-level lapse rates and mid- level drying. Mid- level dry air and long, straight hodographs also indicate the possibility of hail with any discrete storms that develop.
Accordingly, SPC has placed our area in a marginal risk for severe weather tomorrow.
Behind the pre-frontal trough, winds shift to the west and drier low and mid-level air gets advected into the region, which will reduce instability and make convective initiation more difficult. A few additional showers/storms are possible later in the evening for the Mohawk Valley/western Adirondacks ahead of the true cold front, but the severe threat looks more limited at this time with waning instability due to drier air and loss of daytime heating.
Tomorrow night, lingering showers/thunderstorms come to and end in the evening/early in the overnight period as heights rise aloft. The cold front drops southwards across the region, but may not make it all the way to our southern border with OKX. For areas behind the front, northwesterly winds advect cooler and drier air into the region. Lows will generally be in the 40s (north) to 50s (south). Some patchy fog can't be ruled out either, especially ahead of the cold front.
Thursday through Friday...Thursday starts off dry but rain chances increase through the day. A broad, positively tilted upper trough will approach the Great Lakes, and there will be numerous upper shortwaves rotating around this upper trough. At the surface, an area of low pressure will track from the Ohio Valley off the Mid-Atlantic coast, bringing increased chances for showers to the region tomorrow afternoon through Friday. Due to the amount of small-scale shortwaves, there is quite a bit of forecast uncertainty, more than would be expected at this lead time. The best chance for showers will be for areas along and south of I-90, although some sources of guidance suggest showers could make it much further north. Chances for showers continue through Thursday night and into Friday, with a secondary surface low potentially tracking towards our region Friday. Will attempt to refine the timing and amount of precipitation over the coming days with guidance hopefully coming into better agreement. Daytime highs Thursday and Friday will be much cooler than the previous few days, with overnight lows in the 40s to around 50 Thursday night. Severe weather is not expected during the Thursday through Friday timeframe.
LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/
Unsettled and cool conditions describes the weather pattern for the upcoming weekend as a long wave trough remains positioned over the Eastern CONUS with a series of shortwaves tracking from the Midwest into the Northeast. After showers Friday night, some brief ridging and subsidence aloft ensues for at least the first half of Saturday which should support a dry break.
However, an additional shortwave from the Ohio Valley will provide enough lift to support showers returning Saturday afternoon into Saturday night. The shortwave lingers overhead through Sunday with sufficient mid-level moisture and some weak warm air advection as winds aloft shift to the south or southeast. This set-up will maintain chance POPs through the day with even a slight chance for thunderstorms as some instability may sneak northward. While temperatures Saturday remain cooler than normal with highs only in the 50s to low 60s thanks to west-northwest flow aloft, temperatures should trend a bit milder for Sunday rising into the low to mid 60s in the valley with mid to upper 50s in the higher terrain and hill towns.
There remains some uncertainty on how the pattern evolves for Monday into Tuesday as weak shortwaves continue to track aloft while weak high pressure builds at the surface. Therefore, we maintained low end chance POPs for Monday into Tuesday but this may change as guidance becomes into better agreement. Despite the uncertainty in the evolution of shortwaves aloft, there is better agreement for temperatures to trend milder and more seasonable as a milder air mass from the Ohio Valley spills eastward.
AVIATION /00Z WEDNESDAY THROUGH SUNDAY/
Flying conditions are currently VFR with a mostly clear sky in place. Through the late evening hours, it will continue to be VFR with just some thin cirrus. Winds will become light and variable or calm for most areas after sunset.
After midnight, clouds cover will begin to lower and thicken across the region, as a warm front starts to approach. The frontal boundary will allow an area of showers to spread towards the area for the late night hours (after 9z). A stray rumble of thunder can't be ruled out with this activity, but thunder with this looks isolated at this time. Within this batch of moderate rainfall, flying conditions may lower to IFR, as visibility looks to drop towards 2 SM within these showers. This precip will last a few hours, but will be ending 13-15z for all sites.
Behind this initial batch of rain, there will be a few hours where low clouds will keep MVFR cigs around, with ceilings around 1500-3000 ft. By the early to mid afternoon hours, there should be enough break of sun to allow for VFR conditions to return to all sites, with just sct-bkn cigs around 5-7 kft.
However, another round of scattered showers and possible t-storms can't be ruled out for the afternoon into the early evening hours. Some of these storms could be strong with gusty winds, but coverage is still in question at this time. Will include a PROB30 for t-storms at all sites. Once this clear through, winds will become westerly around 10 kts with clearing skies and flying conditions remaining VFR into Wed night.
