Area Forecast Discussion National Weather Service Buffalo NY 813 PM EDT Sun Apr 21 2024

A moisture starved cold front will cross the area tonight with one more reinforcing shot of cooler air that will keep temperatures below average through the start of the new work week, before warmer weather returns for Tuesday. Otherwise, high pressure will build across the area providing mainly dry weather through Tuesday, before unsettled and much cooler weather returns by midweek.

Cyclonic flow associated with upper level trough will maintain breezy conditions through early evening with west to southwest gusts to 25-30 mph.

A moisture starved cold front will cross the area tonight bringing one last shot of cooler air that will keep temperatures below normal through the start of the new work week. Other than a stray light rain or snow shower toward the Saint Lawrence Valley tonight, high pressure builds across the region providing dry weather and lighter winds for tonight through Monday. Chilly night on tap with mid and upper 20s higher terrain and low to mid 30s elsewhere. As mentioned, temperatures will remain below average for Monday, however airmass will modify some. This will yield highs ranging from the mid and upper 40s across the higher terrain, to the low and mid 50s elsewhere.

Main focus this period continues to be on the next round of widespread soggy weather followed by a sharp cooldown around the midweek timeframe.

High pressure will slowly shrink off the East Coast Monday night through Tuesday. This will maintain dry and relatively milder weather to start the period as warmer air advects into the region on the backside of the high. Lows Monday night will range from the low 40s across far western NY to the mid/low 30s across the North Country. As the area sits firmly within the next incoming system's warm sector, highs Tuesday should top out in the low to mid 60s. A 50kt 850H jet embedded within the WAA regime will likely lead to a breezy day northeast of Lake Erie, with gusts of 30-35mph expected.

This system will come in the form of a robust mid-level shortwave sliding east across the Great Lakes Tuesday. As it trudges eastward, this shortwave is expected to partially phase with a deeper closed low wobbling along the eastern shores of Hudson Bay, as well as a weaker shortwave moving across the Mississippi Valley. This will create a deeper longwave troughing pattern that will dig across the Northeast through Wednesday before shifting to the Canadian Maritimes by late Wednesday night. Several waves of surface low pressure are expected to form ahead of the primary mid-level trough axis, with broad-scale cyclogenesis allowing the system to tap into a reservoir of GOMEX based moisture. While a few showers or a stray thunderstorm could reach far western NY late Tuesday afternoon/evening, a swath of soaking rain will move through the region Tuesday night courtesy of broad scale ascent under the poleward exit region of a 110kt upper level jet. Little to no hydrological concerns at this juncture given the dry conditions earlier in the week...Basin averaged QPF amounts through Wednesday morning will average 0.25-0.5" in most areas, a bit higher at 0.5- 0.75" east of the lakes.

The system's main cold front will begin to plow through the region behind the rain Wednesday morning. Mid-range guidance is starting to come into better agreement on the progression of this front and how much cold air spills into the region behind it. Due to discrepancies on the amount of phasing between the shortwave over the Great Lakes and the low near Hudson Bay, previous runs of the GFS were significantly colder (850H temps bottoming out around -12C) than the deterministic CMCNH/ECMWF and their respective ensembles (closer to - 2C). While there remains uncertainty in the timing and true depth of the cold airmass, the trend among the latest guidance has been somewhere in the middle of these solutions, with the overall consensus leaning colder. Should these trends hold, this will support a strong non-diurnal temperature curve with the front Wednesday, with temps sharply falling across the region from the 40s early in the morning well into the 30s through the remainder of the day. While temps at the sfc and aloft will support at least a partial changeover to wet snow, this colder airmass also looks to be quite a bit drier with most of the region precip-free by the afternoon. This, combined with the strong late April sun angle, should greatly minimize the threat of snow sticking anywhere other than the highest hilltops south of Buffalo and east of Lake Ontario.

Within the post-frontal airmass and under mostly clear skies, Wednesday night is expected to be downright cold. Lows will likely be sub-freezing across the entire region, through bottoming out in the low 20s across the higher terrain of the Southern Tier and North Country.

A large Canadian sfc high along with increased ridging will provide dry weather for Thursday and most of Friday. The sfc high will center over the forecast area by Thursday night and track to the New England coast by Saturday morning.

A weakening trough and sfc low will track across the plains on Friday and center over the Great Lakes on Saturday night. This will result in increasing rain potential starting later Friday evening/overnight as the warm front out ahead of the system approaches/crosses the region. Showers and periods of steadier rain will continue through much of Saturday as a plume of GOMEX moisture pushes north across the Ohio Valley. With the warm sector of the system over the region, there will be the chance for some thunderstorms on Saturday, with the best chance for some storms over the southwestern portions of the area. Still some uncertainty as far as shower/rain amount goes among guidance with the GFS keeping the sfc low track closer to the forecast area and keeping the trough a bit stronger as well. Other forecast models limit the moisture influx and pull the sfc low farther north, resulting in less precip overall. Showers should continue into Sunday with more breaks, especially into the afternoon.

Temperatures during the period will be below normal to start with warming each day to above normal by the weekend.

VFR CIGS to continue across all terminal tongiht. Winds will slowly diminish but gusts up to 30 knots will be possible early.

Also...there may be a stray rain or or wet snow shower toward the Saint Lawrence Valley as a moisture starved cold front pushes south across the area but will have little impact on area terminals.

Monday...dry weather is expected as high pressure builds in behind the frontal boundary. VFR again will be found across area terminals.


Monday night...VFR.
Tuesday...Mainly VFR. A chance of showers later in the afternoon.
Tuesday night and Wednesday...Areas of MVFR with showers.
Thursday and Friday...Mainly VFR.

Elevated westerly winds will maintain Small Craft Advisory conditions on Lake Erie and the Upper Niagara River, as well as the eastern end of Lake Ontario through much of tonight. Weaker winds and waves will reside across the waters Monday through Monday night.
Southerly winds will freshen on the waters Tuesday and will likely result in Small Craft Advisory conditions into midweek.

MARINE...Small Craft Advisory until midnight EDT tonight for LEZ020-040- 041.
Small Craft Advisory until 6 AM EDT Monday for LOZ044- 045.
