Area Forecast Discussion National Weather Service Burlington VT 325 AM EDT Sun Jul 5 2020
SYNOPSIS. Temperatures will warm back into the 80s today. Scattered showers and thunderstorms are expected to develop later this afternoon ahead of a weak cold front. Dry weather returns for Monday, before the heat and humidity build by midweek, along with the chances for scattered afternoon and evening showers and thunderstorms.
NEAR TERM /THROUGH MONDAY/. As of 324 AM EDT Sunday . The main concern for today will be the potential for scattered showers/thunderstorms later this afternoon and evening. However, first we will need to deal with an area of showers with embedded thunder that is currently pushing southeast across southeast Ontario/western Quebec. CAM output only just now catching up with this activity, and the consensus shows it holding together long enough to reach the St Lawrence Valley.. There are some indications that although the precipitation will lessen in intensity and coverage as it enters our forecast area, it could flare up again over portions of eastern VT this afternoon, with maybe a rumble of thunder or two.
The better chances for precipitation will be later this afternoon as an upper shortwave rotates southward through eastern Quebec and eventually into northern/eastern New England. Meanwhile, a weak cold front will also move southward, crossing the international border by early this evening. CAMs are now in better agreement that additional convection will fire in response to these two features, though areal coverage and intensity remains more in question. Instability, or lack thereof, will be the main limiting factor as dry air will infiltrate at mid levels. The best instability looks to remain to our south and east, across NH down into eastern MA. Cooler air aloft associated with the approaching upper trough along with daytime heating/mixing will allow for steepening lapse rates however, and 0- 6km shear will be 30-40kt. Hence, expect showers and thunderstorms to develop this afternoon, but coverage will be scattered at best. While some gusty winds and small hail can't be ruled out in any stronger cells, don't anticipate any severe weather at this time. Note that the Day 1 outlook from SPC has the Marginal Risk along the Connecticut River valley eastward, just brushing our eastern VT counties, which seems reasonable. Convection should move out of Canada late this afternoon just ahead of the aforementioned cold front, roughly 3-5 pm, and then push southward through the evening, weakening as we lose daytime heating. Cooler and drier air will spread in the front's wake, leading to clearing skies overnight. Patchy fog could well develop in any areas that do see rain. It'll be a warm day again today as highs reach into the 80s areawide, but Monday will be cooler thanks to the cold front. Highs will range from the upper 70s to mid 80s. Skies will remain mostly sunny with the drier airmass limiting any afternoon convection.
SHORT TERM /MONDAY NIGHT THROUGH TUESDAY/. As of 324 AM EDT Sunday . Low-level winds will turn southwesterly/southerly Monday night as a warm front pushes through. Monday night will be the last night with fairly moderate overnight lows (mid 50s to low 60s) before the heat and humidity get turned up a notch mid-week. Warm air advection will be underway Tuesday, especially over northern NY and the Champlain Valley where temperatures will be in the upper 80s in lower elevations, and mid 80s in higher elevations. Further east, models continue to indicate a slight southeasterly component to the low-level flow over coastal New England and into eastern Vermont, which will keep temperatures around 80 east of the Green Mountains. Most of the area will stay dry Tuesday with ridging suppressing chances for convection. However, could still see a stray thunderstorm or two pop up along the higher elevations of northern NY due to orographic forcing.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. As of 324 AM EDT Sunday . Increasing heat and humidity will be the main story for the long term forecast.
Temperatures Tuesday night will only cool to around 70 in the Saint Lawrence and Champlain Valleys, and into the mid 60s elsewhere. By Wednesday afternoon, 925 mb temps will climb to 22 to 24 deg C, supporting surface highs in the mid 80s to around 90. Dewpoints will be noticeably higher as well, with readings in the mid to upper 60s expected. The upper ridge will flatten out some, resulting in progressive zonal flow over the North Country that will open the door for some weak shortwaves to ripple through. The increasing heat and humidity along with the better potential for weak shortwave energy will support the chance for some scattered thunderstorms developing Wednesday afternoon.
Ridging redevelops Thursday and Friday, leading to yet warmer temperatures (highs in the upper 80s to mid 90s) with dewpoints in the upper 60s to low 70s. Overnight lows will be in the upper 60s to mid 70s, so little relief from the heat during the overnight hours is expected. Heat advisories may be needed for this period. Chances for precipitation are still non-zero Thursday and Friday, but the ridging should keep most of the area dry with only a stray tstorm or two developing over higher elevations.
Temperatures will cool slightly for the weekend and precipitation chances increase as a trough approaches from the west.
AVIATION /08Z SUNDAY THROUGH THURSDAY/. VFR conditions expected at all TAF sites throughout the forecast period. Currently, mid-level clouds are making their way southeastward across the region, resulting in bkn/ovc cigs of ~100k ft. These clouds will continue to move eastward overnight, with a brief break in the clouds to follow. This clearing has already made it over much of northern NY. Additional clouds associated with decaying convection over eastern Ontario/western Quebec will spread over the area toward daybreak. A weak cold front will move out of Canada late this afternoon into the evening, with scattered showers/thunderstorms ahead of its passage. Have stayed with VCSH in the TAFs as coverage not enough to warrant anything more. Convection will wane by 02z-03z, with VFR thereafter. Light and variable winds early this morning will turn to the southwest and remain less than 10 kt, though some gusts to 20 kt will be possible at KMSS and KSLK. Winds switch to north behind the frontal passage.
Monday: VFR. NO SIG WX. Monday Night: VFR. NO SIG WX. Tuesday: VFR. Slight chance SHRA, Slight chance TSRA. Tuesday Night: Mainly VFR, with local MVFR possible. Chance SHRA. Wednesday: Mainly VFR, with areas MVFR possible. Chance SHRA, Chance TSRA. Wednesday Night: VFR. Slight chance SHRA. Thursday: VFR. Chance SHRA, Slight chance TSRA.

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.
