Area Forecast Discussion National Weather Service Burlington VT 316 AM EDT Sun Aug 9 2020
SYNOPSIS. Another round of showers and thunderstorms will be possible this afternoon and evening with the main focus on shower activity being across northern New York. We will see temperatures and humidity increase over the next several days with highs today in the upper 70s to mid 80s increasing to the mid 80s to lower 90 on Tuesday. Portions of the Champlain and St. Lawrence Valleys could see heat indices approach or exceed 95 degrees. Additional showers and thunderstorms will also be possible on Tuesday as a front approaches the region. Unsettled weather will continue into the second half of the upcoming week but temperatures will be closer to seasonal normals.
NEAR TERM /THROUGH MONDAY/. As of 316 AM EDT Sunday . Cloud cover will continue to increase across the North Country as we have a compact yet robust shortwave approach from the west. The first half of the day looks to be on the dry side but that will change by mid-afternoon as we see showers and thunderstorms develop ahead of the aforementioned shortwave. Precipitable waters ahead of this feature will climb from 1.2" to nearly 1.7" and we will see that reflected at the surface as increasing dewpoints through the morning and early afternoon hours. With decent divergence aloft associated with a PVA maximum we could see some thunderstorms across northern New York but once again getting a surface based thunderstorm this afternoon will be a little tricky as we see a warm and stable layer around 850 mb. Nevertheless, we could see some efficient rain makers this afternoon and into this evening as this system moves through New York. In Vermont, we will have more CIN than CAPE so we went ahead and removed mention of thunderstorms for much of Vermont. The latest NAM3 and ARW all show this feature fizzling out as it moves overhead so our rainfall amounts will decrease from west to east. We could see an isolated shower or thunderstorm on Monday as we remain right on the edge of the mid- level height rises ahead of a more progressive and deeper trough moving across the Great Lakes. We are getting back into a warming pattern across the North Country over the next two days with highs this afternoon in the upper 70s to lower warming into the lower to upper 80s on Monday. Dewpoints will climb into the upper 60s to near 70 degrees as southerly flow at the surface and 850 mb allows for strong moisture advection. While we will likely fall short of heat advisory criteria on Monday, it's sure to be a hot and muggy day.
SHORT TERM /MONDAY NIGHT THROUGH TUESDAY/. As of 256 PM EDT Saturday . Aforementioned upper trough exits east of the region early Monday morning with a weak upper ridge over the eastern Great Lakes poised to track over the North Country during the afternoon and evening hours. The result will be tranquil conditions through the period with clearing skies through the day/night. Monday will begin a brief warming trend back above normal with increasing humidity and dewpoints back into the upper 60s to lower 70s. 925mb temps of +20- 22C support highs in the mid/upper 80s and increasing south/southwesterly flow will provide milder overnight temps only falling into the upper 60s to lower 70s.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. As of 256 PM EDT Saturday . Deep southwest flow becomes established over the forecast area Tuesday ahead a weak shortwave trough and surface boundary progged to track into the region Tuesday afternoon and evening. Ahead of this feature heat and humidity persists with 925mb temps perhaps a degree or two higher than Monday supporting highs in the upper 80s to lower 90s. With dewpoints the mid 60s to lower 70s, sufficient instability will be present during peak heating into the evening hours to support shower and thunderstorms development, mainly across central and northern zones. With the loss of diurnal heating though the thunderstorm threat will wane after sunset, but the surface boundary will stall over the region Tuesday night through Wednesday night before shifting southeast Thursday. Not much dynamical support aloft during this period so precipitation will be more diurnally and instability driven but can't rule out showers during the overnight hours either with a moist boundary layer present. Temps Tuesday night through Thursday night remain above normal with highs ranging through the 80s, warmest Weds, and lows in the mid/upper 60s.
Drier conditions look to return Friday into Saturday as high pressure settles over t expected this evening/tonight under weak high pressure and light winds. An isolated early evening shower or storm will be possible as lingering slope flows and/or the Lake Champlain lake breeze foster localized moisture convergence but most areas will remain dry overnight. Lows seasonable from 55 to 65 with patchy fog or mist, most prevalent in eastern VT valleys/hollows.he Canadian maritimes.
AVIATION /07Z SUNDAY THROUGH THURSDAY/. Through 06Z Monday . Expecting VFR conditions and light winds to persist through the forecast period. While there may be a few pockets of low stratus in the Connecticut River Valley, the increasing cloud cover should prevent sites from reaching their crossover temperatures and fogging in. We will see showers develop ahead of an upper level disturbance this afternoon and evening. Conditions will likely remain VFR with these showers but an embedded rumble of thunder or two over New York will be possible this afternoon.
Monday: Mainly VFR, with local MVFR possible. NO SIG WX. Monday Night: VFR. Slight chance SHRA. Tuesday: VFR. Chance SHRA, Chance TSRA. Tuesday Night: VFR. Chance SHRA, Chance TSRA. Wednesday: Mainly VFR, with local MVFR possible. Chance SHRA, Chance TSRA. Wednesday Night: VFR. Chance SHRA, Slight chance TSRA. Thursday: VFR. Chance SHRA, Slight chance TSRA.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.
