Area Forecast Discussion National Weather Service Burlington VT 341 PM EDT Sat Jul 11 2020

SYNOPSIS. Expect isolated to scattered showers across the North Country this afternoon and evening. There may also be some thunderstorms, especially over northern New York and southern Vermont, and the potential for heavy downpours will exist with these storms. Overnight expect additional showers across the North Country as a low pressure system moves across the area. Some lingering showers and isolated storms will exist throughout the day on Sunday with temperatures at or slightly above seasonal normals.

NEAR TERM /THROUGH SUNDAY NIGHT/. As of 341 PM EDT Saturday . Forecast remains on track for greater areal coverage of convection tied to shortwave trough over western New York this afternoon. Instability has developed ahead of this feature across central and southeast New York with at least slightly better flow aloft to support an increased chance of organized convection. Clearing starting to take place across northern New York and Vermont and we have seen some showers tied to the tail end of moisture from what was once Fay. Almost seems like a little subsidence on the back side of this moisture is limiting convective development at the moment over our area. Feel the chances for convection start to better increase after 500 pm when we lose the subsidence and start to get under the flow from the upstream shortwave. Still think the threat of strong to severe storms will remain south of our area, but we could see some brief heavy downpours with the high precipitable water air over the area. We should lose the thunder threat after sunset and as the shortwave trough weakens and lifts up over our area we may actually see a better chance for showers during the overnight hours. This feature will be right over the New York and Vermont borders around daybreak and then move east as the day progresses on Sunday. Best forcing shifts east and with limited instability feel we could see some showers during the afternoon hours, but thunder threat may be a bit limited. High dew points over the area will keep lows tonight in the 60s to around 70 with highs on Sunday getting into the upper 70s to middle 80s.

SHORT TERM /MONDAY THROUGH MONDAY NIGHT/. As of 341 PM EDT Saturday . A closed upper low with embedded shortwave energy will bring cloudy skies and chances for rain to the North Country on Monday. A weak frontal boundary will accompany the passage of the aforementioned low, aiding in the development of rain showers with some embedded thunder during the afternoon and evening. As of 337 PM EDT Saturday. In addition, prevailing cloudy skies will limit the magnitude of diurnal heating, and thus, instability. Overall, 0.25-0.5 inches of rain is expected throughout the day Monday and Monday night with the highest amounts located across the higher terrain of the Adirondacks and Green Mountains. West winds Monday will be light (5mph or less), becoming northwest as a surface low develops off the coast of Cape Cod. Temperatures Monday will feel a bitter cooler than the past few days, with highs reaching upper 70s/low 80s and overnight lows in the upper 50s/low 60s.

LONG TERM /TUESDAY THROUGH SATURDAY/. As of 341 PM EDT Saturday . A progressive pattern is in store for the remainder of the week with periodic chances for rain. During the day Tuesday, the upper level low will begin its departure eastward, bring ongoing chances for rain, especially across eastern Vermont. However, dry weather is expected mid- week under the influence of ridging aloft and subsequent high pressure at the surface. By the end of the week, another low pressure system approaches the North Country, bringing with it a chance of widespread showers focused along a frontal boundary. The exact timing of its passage is still to be determined, though model guidance is currently indicating it will be sometime Friday. Temperatures throughout the week will be near normal, with daytime highs reaching low 80s and overnight lows in the upper 50s/low 60s.

AVIATION /20Z SATURDAY THROUGH THURSDAY/. Through 18Z Sunday . VFR to MVFR ceilings and visibilities will be the rule across the area throughout the entire period. Isolated to scattered showers are expected and the best potential for any thunderstorms will exist between 18z and 02z . where periods of IFR conditions will likely occur. Winds will be from the south and southwest this afternoon with gusts in the 15 to 25 knot range. The winds will taper off a bit tonight then become more west and southwest after 15z on Sunday . but speeds will generally be 15 knots or less.

Outlook .

Sunday Night: VFR. Slight chance SHRA, Slight chance TSRA. Monday: VFR. Chance TSRA, Slight chance SHRA. Monday Night: Mainly VFR, with local MVFR possible. Chance SHRA, Chance TSRA. Tuesday: Mainly VFR, with local MVFR possible. Chance SHRA. Tuesday Night: VFR. Slight chance SHRA. Wednesday: VFR. Slight chance SHRA. Wednesday Night: VFR. Slight chance SHRA. Thursday: VFR. Chance SHRA, Chance TSRA.

MARINE. A Lake Wind Advisory remains in effect for Lake Champlain, mainly through the evening hours. South winds of 15 to 25 knots will create 2 to 4 foot waves and produce rather choppy conditions on the lake, especially over the northern half. Scattered showers and isolated thunderstorms are expected late this afternoon and tonight with the thunderstorm threat mainly through this evening. Lightning and heavy downpours will be the main threats with any storms.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
