SYNOPSIS. Low pressure passing by to the north of Lake Ontario will continue to produce a few rain showers across the North Country this evening and gusty winds across Western NY. Colder air in the wake of front will send our temperatures back below normal Thursday with a few light snow showers possible in the morning southeast of Lakes Erie and Ontario. Our region will then become progressively milder as we head into the weekend.

NEAR TERM /THROUGH THURSDAY NIGHT/. Low pressure passing by to the north of Lake Ontario will continue to produce rain showers east of Lake Ontario this evening as a trailing cold front crosses the region. A few showers may also clip southeast Allegany County early this evening. Otherwise the rest of the area has become dry, at least temporarily. A few upslope and lake enhanced rain/snow showers may develop by late evening across the higher terrain east of Lake Erie as low level moisture and cold air move back into the region.

Gusty WSW winds are weakening this evening as the strongest winds aloft move northeast of the area. There will still be gusts to around 30 knots across much of the region this evening, but peak gusts are down from the 35-40 knot range observed earlier this evening in a few locations northeast of Lake Erie. Overnight winds will become more WNW, with gusts still in the 30-40 mph range along the southeast shore of Lake Ontario.

Colder air in the wake of the front will change residual light rain showers to snow showers tonight with a coating to an inch possible east of Lake Ontario. Cold advection to continue into Thursday with H85 temps lowering to -12c. The vast majority of the region will remain below freezing throughout the day as a result, especially across the Eastern Lake Ontario region and in the higher terrain of the Srn Tier. Still only looks like a minimal lake response off Lk Ontario with nuisance lake snow showers southeast of the lake in the morning beneath a cap of 5kft. Lake snow potential may increase some on Thursday night as weak system crosses to add a bit of enhancement potential. Marginal setup overall with H85 temps only around -12c and majority of lift and moisture not in the DGZ, so kept snow amounts only of an inch or two for the night southeast of Lake Ontario. Seasonably cool for Thu night otherwise with lows in the teens to lower 20s.

SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/. Strong high pressure building across the region from the west should provide dry conditions for Friday and the majority of Friday night. Temperatures will be close to climatological normals on Friday, with highs averaging in the mid 30s for much of the area, with upper 20s to low 30s across the North Country.

A warm front extending east from low pressure moving through the upper Great Lakes will move through the area Friday night and Saturday morning, bringing the next round of precipitation. Models remain in fairly good agreement that strong warm advection/forcing in combination with low-level Atlantic/GOMEX moisture advecting northward on the west side of strong high pressure off the East Coast will produce some light snow across the area Friday night into Saturday morning. A trailing cold front will then cross the area Saturday afternoon, keeping the threat for precipitation throughout the day. The aforementioned strong warm advection ahead of the boundary will cause any snow to mix with then change to plain rain area wide during the second half of the day ahead of the cold front. Recent model trends have nudged the bulk of the heavier precipitation further north--combined with temperatures a bit more sluggish to rise on the higher elevations across the Tug hill and western Adirondacks, a quick coating of an inch or two is possible Saturday morning. Lows will fall into the 20s Friday night before warming up into the low to mid 40s on Saturday.

Any lingering light precipitation east of Lake Ontario will change back to snow Saturday night as airmass becomes just cold enough in the wake of the cold front to support frozen precip at the surface overnight.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. An area of low pressure will track northeast across the Great Lakes on Sunday. As this system tracks north of the area, its associated cold front will cross the region Sunday evening into early Monday morning. Showers will be possible, but the best chance looks like it should be well north and south of the area, associated with the main low pressure to the north and another developing area of low pressure well south of the region.

A clipper should move through on Monday, bringing the potential for showers across the region. Following this passing clipper, cold air advection may be strong enough to cause some sub -10C 850H temperatures. Which would result in a lake response off of both lakes. Guidance is still in some disagreement at this point for how cold the 850H temps get, but it looks like there could be at least a weak response Monday night into Tuesday morning.

From Tuesday morning onward, guidance is in general agreement that high pressure will be in place for Tuesday into early Wednesday morning. Beyond that, guidance has greater spread in the forecast, with some guidance favoring the more southern stream to bring systems north vs other guidance that favors more of the northern stream and the potential for systems to drop out of Canada.

Temperatures for the long term period will start out warm in the mid to upper 40s for most locations on Sunday, maybe a few low 50s. Behind the passing front on Sunday evening, temperatures will cool to the upper 30s and low 40s for Monday. Tuesday looks like it will be the coldest day with temperatures in the upper 20s to low 30s. Temperatures will start to warm backup some for Wednesday with highs in the upper 30s to low 40s for most areas, except for a few 30s for the Tug Hill.

AVIATION /01Z THURSDAY THROUGH MONDAY/. A few rain showers will continue east of Lake Ontario this evening as low pressure passes just north of our region and a trailing cold front crosses the North Country. VFR CIGS initially this evening will deteriorate to MVFR from west to east tonight as low level moisture moves back into the region. Some spotty IFR is possible across higher terrain as well. A few snow showers will develop overnight east and southeast of Lakes Erie and Ontario with spotty MVFR VSBY. This will continue into Thursday morning before mostly ending by early afternoon. MVFR CIGS will continue to be fairly widespread through Thursday morning, then improve to mainly VFR in the afternoon.

Outlook .

Thursday Night . MVFR/local IFR with a chance of snow showers. Friday . Mainly VFR. Saturday . VFR/MVFR. A chance of rain or snow showers. Sunday . VFR. Chance of rain showers. Monday . MVFR. Chance of rain and snow showers.

MARINE. Low pressure tracking across southern Ontario will push a relatively strong cold front through the Lower Great Lakes this evening. As a result strong west to southwest winds will continue this evening, then become more WNW overnight.

Winds will gradually subside late tonight and Thursday as the area of low pressure will exit across the Saint Lawrence valley and northern New England. This should allow the SCA for Lake Erie to expire at 06z.

The SCA's for Lake Ontario will remain in place into Thursday . as waves will take a little longer to subside in the cold air advection within the weakening wind field.

BUF WATCHES/WARNINGS/ADVISORIES. NY . None. MARINE . Small Craft Advisory until 10 PM EST this evening for LEZ020. Small Craft Advisory until 1 AM EST Thursday for LEZ040- 041. Small Craft Advisory until 10 PM EST this evening for LOZ030. Small Craft Advisory until 4 PM EST Thursday for LOZ043- 044. Small Craft Advisory until 7 AM EST Thursday for LOZ042.
