AREA FORECAST DISCUSSION National Weather Service Albany NY 625 AM EST Sun Feb 23 2020

SYNOPSIS. After a chilly start, plenty of sunshine will lead to a mild afternoon today. More dry and mild weather is expected for tomorrow, but some light precipitation in the form of rain and mountain snow will return for Tuesday through Thursday. Colder temperatures will return by late in the week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 625 AM EST . IR satellite imagery shows completely clear skies for areas from the Mohawk Valley and Capital Region on southward. Northern areas are mostly clear, with just some thin patches of high clouds passing west to east across the region. Temperatures range from the teens to 20s this morning, with the coldest temperatures across sheltered northern valley areas.

Our region is under the influence of zonal flow aloft. At the surface, a large area of high pressure is located south of the region over the Southeast and mid Atlantic States. Through the day today, this high pressure area will slowly drift eastward. As a result, sky cover today will remain mostly sunny, with just some thin passing high clouds (mainly for northern areas).

With full sunshine in place and mixing to nearly 850 hpa, it should be a fairly mild day across the region. Have leaned towards the warmer guidance based on recent trends, with valley highs in the mid 40s to low 50s. High terrain areas should top out in the upper 30s to low 40s. Winds will be lighter than yesterday, with just a light south to southwest breeze in place.

SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY NIGHT/. Dry and quiet weather will continue into the overnight hours for tonight. With the high pressure nearby and just off the eastern seaboard, skies will remain fairly clear and winds will be light or calm. Despite the decent radiational cooling setup, temps will be falling from the warmer afternoon today and some valley areas won't have much of a snowpack in place. Considering all this, won't go too far below guidance for most areas, with lows generally in the 20s to near 30. Still, a few spots (especially sheltered northern areas) will have a locally cold night in the upper teens.

On Monday, the dry weather will continue, although clouds will be increasing through the day with the persistent south to southwest flow in place. Despite the increasing clouds, warming temps aloft will still make for a rather mild day, with highs in the mid 40s to mid 50s for much of the region. Much of the region should become overcast by Monday night, but model trends are for the dry weather to continue through most of the night with lows in the 30s.

By Tuesday into Tuesday night, there will be the chance for some light precipitation to return, as isentropic lift/warm advection increase across the region. Although the main low pressure system will well west of the area across the Midwest and Great Lakes, the south to southwest flow should promote some light precipitation to develop across the region. Models still don't agree on the exact timing, but chance look to increase for Tuesday evening into Tuesday night, as a band of precipitation lifts from south to north across the area. Along with the warming temps aloft, the boundary layer looks fairly warm as well, so most areas will be seeing primarily rain. Can't totally rule out some wet snow at the onset for all areas, and far northern/high terrain areas could see snow or sleet linger a little bit longer, but p-type will generally be mainly rain. Amounts look very light, with total qpf for Tuesday into Tuesday night generally under a quarter of an inch, and as snow accumulation (limited to high terrain areas) will be just a coating to an inch. Temps should warm into the mid 30s to mid 40s for highs on Tuesday. By Tuesday night, a backdoor boundary could allow for low-levels winds to switch to the north to northeast, which may allow for surface temps to lower across northern and eastern areas by later Tuesday night. This is what may help linger any wintry precip for these northern and high terrain areas of southern VT/northern Berkshires, as surface temps fall back into the 30s for late Tuesday night.

LONG TERM /WEDNESDAY THROUGH SATURDAY/. Closed upper low develops over the Great Lakes and tracks just north of the U.S./Canadian border Wednesday through Friday. Trailing upper energy keeps mean upper troughing and northern stream upper energy over our region through Saturday.

Warm advection, moisture advection and isentropic lift will result in increasing coverage of rain through Wednesday. The leading edge of deep cooling and a boundary layer wind shift from south and southeast to west is timed for late Wednesday night and early Thursday. Rain will transition to rain and snow showers with the cold frontal passage.

Highs Wednesday in the 40s but upper 30s higher terrain. Highs Thursday in the upper 30s to lower 40s but lower to mid 30s western and northern areas. Temperatures could drop Thursday afternoon in eastern NY and western New England.

West flow off the Great Lakes along with lingering moisture and upper dynamics should support lake effect snow activity extending into the western Mohawk Valley and southern Adirondacks with some upslope snow possible into the southern Green Mountains of VT, the Taconics and Berkshires. Some scattered to isolated rain and snow showers are possible in the Capital Region and Hudson Valley. There could be some considerable accumulations of lake effect and upslope snow Thursday through Friday, depending on the timing of the exit of the moisture, the upper dynamics and the specific low level wind direction.

Gradual decrease in coverage of rain and snow showers Friday and Saturday with the slow exit to the upper troughing. By Saturday, any snow shower activity is expected to be confined to parts of Herkimer County. Still, the core of coldest air will linger as will west to northwest low level flow that could be gusty at times. Highs Friday around 30 to mid 30s but around 20 to mid 20s higher terrain. Highs Saturday in the upper 20s to lower 30s but some mid 30s southern areas and upper teens to mid 20s higher terrain.

AVIATION /12Z SUNDAY THROUGH THURSDAY/. High pressure in control of the weather. Just a few clouds well above 3000 feet around KGFL this morning before they exit. Some high clouds above 20000 feet at times through the day everywhere. VFR conditions will prevail through tonight.

Variable to west and southwest winds at 6 Kt or less will become south to southwest by mid to late morning at around 6 Kt. Winds will diminish to near calm this evening and continue near calm tonight.

Wednesday: High Operational Impact. Likely RA. Wednesday Night: High Operational Impact. Likely RA. Thursday: High Operational Impact Likely SHRA. SHSN. Thursday Night: Moderate Operational Impact. Slight Chance of SHSN. Friday: Low Operational Impact. Breezy. Slight Chance of SHSN.

HYDROLOGY. Dry weather is expected to continue through Monday, allowing for river and stream levels across eastern New York and western New England to remain steady. Although overnight lows will be below freezing, daytime highs will be rising above freezing for most areas and will be above normal.

There will be a chance for some light precipitation to return Tuesday into Tuesday night, with a better chance for more appreciable precipitation on Wednesday into Thursday. At this point, amounts don't appear large enough to have a big hydrologic impact, although some minor rises are possible. Although temperatures will continue to be mild through the middle of the week, colder weather looks to return for the late week.
