Area Forecast Discussion National Weather Service Buffalo NY 137 AM EDT Sun Apr 21 2024

High pressure builds across the area tonight, bringing mainly dry weather that will last through the first part of the new work week.
Temperatures will be below average through Monday, before returning to near normal levels by Tuesday.

IR satellite imagery shows mostly cloudy skies across western NY and portions of north central NY late tonight. Models continue to not recognize the eastward extent of this stratus deck which has now moved into the Finger Lakes region/central NY. With a weak surface trough approaching overnight, the stratus deck will hold especially across far western NY with some clearing expected across the Finger Lakes region and north central NY into the early morning hours. This trough may set off a few sprinkles or light rain shower across WNY where deeper moisture is found.

Lows tonight will drop into the upper 20s east of Lake Ontario, and near the State Line. Across much of WNY and towards the Finger Lakes where clouds will hang on through much of the night, lows will generally range through the mid to upper 30s.

Surface high pressure will be control for Sunday with mainly dry conditions expected. However, with the main upper level trough remaining in place aloft expect below normal temperatures and breezy conditions to develop once again, but not as windy as today as a 35 knot LLJ will be absent. Highs will be mainly range through the 40s, with some low 50s for the traditionally warmer spots. Another cold front will approach late Sunday, however any precipitation associated with the boundary will remain north of the area/nearing the Saint Lawrence Valley through the end of the day.

A cold front albeit dry (moisture starved) is advertised to drop south out of Canada Sunday night. We might see an isolated rain or snow shower focused mainly across the St. Lawrence valley. Have low end PoPs (20% or less) there, elsewhere it is 'likely' to remain dry
With its passage
a colder air mass will quickly sweep in behind the front with 850H temps briefly down to -10C by Monday morning. Modification of this chilly airmass then quickly occurs by Monday afternoon. Given full late April sunshine we should see temps push into the 40s east of Lake Ontario, with a range of 40s to low 50s found elsewhere.

Dry weather will persist Monday night with the ridge of high pressure overhead slowly drifting to the eastern seaboard. Cold night expected with lows in the 30s for most locales.

Tuesday...dry weather will slowly give way to increasing chances for showers as a potentially strong cold front drops southeast across the upper Great Lakes region
At this point
there still remains a fair amount of uncertainty as guidance shows a wave (elongated) or waves of low pressure developing along the front. There is also varying degrees of QPF, and then how cold does it may get behind the front. The GFS is 'very' cold (potential outlier) behind the front to the tune of -11C to -13C at 850H. Thinking the GFS is way too cold but just can't completely write it off just yet
That said
we will need to see more run to run consistency
Even so
it is looking fairly wet with widespread rain Tuesday night as the front works into the region.

Heading into Wednesday morning, a robust albeit weakening mid-level shortwave will be sliding east across the region. This feature will be partially coupled with a deeper closed low just east of Hudson Bay, with an elongated wave of surface low pressure ahead of the system's primary cold front extending from the Ohio Valley to northeastern Quebec. A more distinct area of cyclonic flow at the surface in the vicinity of the eastern Lake Ontario region will quickly move in tandem with the southernmost shortwave, sliding east into New England by the afternoon. There remains some uncertainty in the strength of this surface wave over the eastern Great Lakes, which will likely influence additional rainfall amounts and the speed at which this initial cold front exits the region. The overall trend will support the steadier more widespread rain beginning to taper off across the western zones through the day, though the latest CMCNH/ECMWF solutions indicate a bit more in the way of low- level moisture and lighter wrap around showers sticking around into Wednesday evening. Otherwise, it will be notably cooler Wednesday with highs only in the 40s to low 50s.

Extra cloud cover and a few lingering showers could be weakly forced by a secondary cold front that will sag southward into the region late Wednesday into early Wednesday night, though a large expanse of surface high pressure building across the Great Lakes and southeastern Canada will lead to mainly dry weather across the region overnight. A much cooler airmass will filter into the region behind the secondary front which will support a rather chilly night, as well as perhaps a brief mix with wet snow before the precip completely tapers off. Though as mentioned previously in the short term discussion...There is still an enormous discrepancy in how cold this airmass gets between the deterministic ECMWF/CMCNH and GFS solutions, as well as their respective ensembles. While the former have consistently advertised 850H temps dipping to around -5C overnight, the GFS continues to show temps closer to -13C. Will continue to lean on the former and the NBM which support lows in the low 30s to upper 20s across the hilltops, as opposed to widespread 20s advertised by the latter.

Other than a stray upslope shower across the Tug Hill/Western Dacks Thursday morning, expect another cool albeit much drier day as high pressure at all levels builds east over the region. Next chances for rain will arrive Friday night and last through Saturday as the high moves east of the region near the end of the week, supporting a strong warm front that will move into the region from the southwest.
This will also initiate a warming trend, with temps averaging above normal Friday and especially Saturday.

VFR conditions will continue across western and north central NY through Sunday evening.

A stratus deck with ceilings averaging 4-6k feet will remain across western NY and portions of north central NY overnight. A weak surface boundary will move through the region Sunday. This will lower ceilings slightly across the higher terrain including KJHW through Sunday morning.

Strato cumulus will form along lake breezes Sunday resulting in ceilings 3-5k feet from KIAG/KBUF to KROC and beyond. FEW-SCT ceilings will be across KJHW and KART. Clouds will diminish into Sunday evening.


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

Winds will temporarily diminish again tonight with small craft advisories ending, then the winds increase again tomorrow with another period of solid westerly flow Small Craft Advisory conditions on Lake Erie and Lake Ontario. Overall, a poor weekend for boating with chilly temperatures, strong winds, and high waves much of the time.

MARINE...Small Craft Advisory until 2 AM EDT early this morning for LOZ044-045.
