Area Forecast Discussion National Weather Service Burlington VT 304 PM EDT Sun Aug 9 2020

SYNOPSIS. A weak upper disturbance will bring clouds and a few showers to the region through early this evening, otherwise quiet weather is expected into Monday. Hot weather arrives for Tuesday with increasing chances of showers and storms by late afternoon into evening with the approach of a weak front. A few showers linger across southern counties into Wednesday along the departing front, otherwise fair and seasonably warm late summer weather is expected for the back half of the work week onward into next weekend.

NEAR TERM /THROUGH MONDAY NIGHT/. As of 304 PM EDT Sunday . A weak upper trough passage still looks on track for this evening with scattered to broken mainly mid level clouds and a period of scattered showers. Shower activity will be most focused through the mid evening hours as modest PVA and moisture convergence traverses the area ahead of a weak vorticity center in the base of the trough. Low temperatures by early Monday morning to generally range through the 60s along with patchy areas of mist/fog in favored river valleys/hollows of the Adirondacks and eastern Vermont.

Mainly quiet and seasonably warm weather is expected for Monday into Monday night as weak shortwave ridging skirts across the Northeast. I can't completely rule out a stray shower or isolated storm during peak afternoon heating, but forcing remains weak in concert with a modest mid level capping inversion near 850 mb. It will begin to feel more humid under light south/southwesterly flow with surface dewpoint values creeping up into the mid 60s to lower 70s by later in the day. Highs to range generally from 82 to 88 degrees, warmest in the broad valleys with corresponding lows Monday night from the mid 60s to lower 70s.

SHORT TERM /TUESDAY THROUGH WEDNESDAY/. As of 304 PM EDT Sunday . No major changes to the forecast for mid- week which highlights continued heat and humidity Tuesday followed by a frontal passage Tuesday afternoon through Wednesday. Guidance continues to point at Tuesday being the hottest and most humid day of the week as deep southwesterly flow will tap into a warm and humid air mass over the southeast. Mean 925mb temps of +22-24C support highs well into the upper 80s and locally lower 90s in the Champlain and Lower Connecticut River Valleys where heat indices will likely exceed 95 degrees as dewpoints climb into the upper 60s to lower 70s. A heat advisory will likely be needed for these locations. With this heat and humidity in place there won't be any lack of surface instability, and as a weak cold front approaches from the west we should see scattered showers and thunderstorms develop during the mid/late afternoon and persist into the evening. A lack of any deep layer shear should mitigate any organized severe threat, but with progged DCAPE's 1000-2000 J/kg and high PWATS of 1.5-2" we could see a few stronger cores aloft capable of producing isolated wet microbursts.

Heading into Tuesday night the convective threat will wane with the loss of daytime heating, but enough forcing will be present aloft to continue the chance for scattered showers through the night as the aforementioned surface boundary slowly sags southeastward into central portions of the forecast area. By mid-morning Wednesday guidance points to the boundary being across southern zones, with a brief window for additional showers and thunderstorms possible during the afternoon there. Northward, Wednesday should be mainly dry with temps area-wide cooler in the low/mid 80s and decreasing humidity from northwest to southeast through the day.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. As of 304 PM EDT Sunday . With the passage of the aforementioned surface front late Wednesday, the remainder of the work week and into next weekend is looking very pleasant as surface high pressure builds southeastward across southern Quebec Thu/Fri, and offshore Sat/Sun. A building ridge aloft will help to support mainly sunny skies and clear nights as well with temperatures slightly above seasonal normals, but only slightly with highs in the low/mid 80s and lows in the mid 50s to low 60s. Humidity will be tolerable as well with afternoon dewpoints dropping into the mid 50s to around 60 each day.

AVIATION /19Z SUNDAY THROUGH FRIDAY/. Through 18Z Monday . Mainly VFR through the forecast cycle. Weak upper disturbance to bring SCT/BKN cigs generally in the 050-100 AGL range with scattered -SHRAS with cigs briefly lower to 035 AGL through 00-06Z depending on terminal. Some patchy MVFR/IFR fog/br also possible at KMPV/KSLK/KMSS overnight in the 06-12Z time frame on Monday. Winds mainly less than 10 kts through the period with terminal dependent variability governed heavily by terrain, valley or lake breeze flows.

Outlook .

Monday Night: VFR. NO SIG WX. Tuesday: VFR. Chance SHRA, Chance TSRA. Tuesday Night: VFR. Chance SHRA, Slight chance TSRA. Wednesday: VFR. Chance SHRA, Slight chance TSRA. Wednesday Night: VFR. Slight chance SHRA. Thursday: VFR. Slight chance SHRA. Thursday Night: VFR. NO SIG WX. Friday: VFR. Slight chance SHRA.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
