Area Forecast Discussion National Weather Service Burlington VT 350 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 349 AM EDT Sunday . Monday night through Tuesday is still on track to be the hottest part of the week. Deep southwesterly flow will tap into a warm and humid air mass over the southeastern US. By Tuesday afternoon, 850 mb temps will climb to near 20 deg C, which will support surface highs in the low to mid 90s for much of the area. Highest temperatures (93-94 deg F) are expected in lower elevations of the southern Champlain Valley, along with lower elevations of the Connecticut Valley in Windsor County. Humidity levels will be quite high as well . dewpoints expected in the upper 60s to low 70s. Apparent temperatures will be in the mid 90s for lower elevations, and some heat advisories may be needed for Tuesday. With all the instability around, should see some scattered thunderstorms develop during the afternoon, especially over higher terrain. Precipitable water values will be around 1.5 to 1.6 inches, so thunderstorms could contain some heavy rainfall. Deep layer shear is very weak, so it will be difficult to get much organization with the thunderstorms which will highly limit the severe threat. However, with pretty high instability (between 1000 and 2000 J/kg generally progged depending on model), relatively high PWats, and forecast soundings showing some dry air in the mid-levels, could see some wet microbursts/locally gusty winds out of any thunderstorms that do develop.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. As of 349 AM EDT Sunday . A front will move through late Tuesday into Tuesday night. The nocturnal timing of the frontal passage as per current guidance will limit the impact of the frontal passage with waining instability overnight. Should see some showers with a few embedded tstorms during the overnight hours as the boundary moves through. Wednesday afternoon looks dry for much of northern NY, but VT may see some lingering showers. Highs will be in the 80s. Once the front clears the area, should see an extended period of quiet weather with Canadian high pressure building in from the north. Highs for the second half of the week will generally be in the upper 70s to mid 80s.
AVIATION /08Z 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.
