Area Forecast Discussion National Weather Service Burlington VT 347 AM EDT Sat Aug 8 2020
SYNOPSIS. Scattered showers and thunderstorms will develop across the higher elevations of the Green and Adirondack Mountains this afternoon. These showers will taper off this evening with loss of heating and drier weather will continue tonight and Sunday. A warming trend will start on Sunday as highs warm into the lower to mid 80s. We could see places in the Champlain and St. Lawrence Valley push 90 degrees once again as early as Monday with above normal temperatures expected through next week. Drier weather will continue through the first half of next week before wetter and unsettled weather makes a return on Wednesday.
NEAR TERM /THROUGH SUNDAY/. As of 336 AM EDT Saturday . A few showers moved across southern Vermont as weak PVA led to some decent upward vertical motions. However, the environment has remain highly capped leading to these showers to be short-lived and very light in nature. We will see any lingering shower activity shift eastward shortly after sunrise as a shortwave trough swings through the region. Another very nice summer afternoon is in store for the North Country as we see partly sunny skies prevail across the region with highs once again in the upper 70s to lower 80s. We will see some showers and possibly a thunderstorm or two form over the high peaks of the Adirondack and Green Mountains today as we have a pocket of colder air aloft underneath the aforementioned shortwave trough. With the colder air aloft, our lapse rates this afternoon will aid in creating a few hundred J/kg of CAPE. While we could see a few of these thunderstorms ultimately become rooted in the boundary layer, a loft of the instability will remain elevated. This basically means we could have some brief moderate rainfall and a few rumbles of thunder without the concern of any hail or strong wind gusts. Any convection that does fire this afternoon will quickly dissipate this evening with the loss of diurnal heating. Quieter weather is expected tonight and again on Sunday as a weak shortwave tracks just north of the international border. Temperatures warm into the lower to mid 80s on Sunday which looks to be the first day of a warming trend as we head into next week.
SHORT TERM /SUNDAY NIGHT THROUGH MONDAY/. As of 346 AM EDT Saturday . A compact shortwave will skirt the northern part of the forecast area Sunday night, so can't rule out a shower or two overnight near the Canadian Border. The rest of the forecast are should remain dry overnight. Lows will be in the low to mid 60s. Once the shortwave moves downstream by midday Monday, increasing heights will keep the area mainly dry for the remainder of the day with the exception of a few showers possible over the northern Adirondacks. No large-scale forcing present, however will see warm air advection and moisture advection through the day on westerly flow, which will increase instability to the point where a few showers may be able to pop up over higher terrain once the ridge axis moves to our east. Highs Monday will be in the mid to upper 80s.
LONG TERM /MONDAY NIGHT THROUGH FRIDAY/. As of 346 AM EDT Saturday . Flow turns increasingly southwesterly Tuesday, ushering in warmer, moist air from the Ohio River Valley to the North Country. Will see increasing instability Tuesday as temperatures rise to near 90 and dewpoints rise into the upper 60s/low 70s. Focused forcing for ascent arrives Tuesday night as a front moves crosses the forecast area from west to east. At this point, it looks like the front will move through overnight, which will limit instability and decrease the t-storm potential. However, if the timing shifts either way, could see an increase in t-storm threat. Deep layer shear is marginal, so not expecting any organized severe storms regardless of the exact timing of the frontal passage. The front may stall over our forecast area into Wednesday, and if the boundary remains overhead Wednesday afternoon, would see a better chance for some (mainly non-severe) t-storms. However, if the boundary were more progressive, chances for showers and thunderstorms Wednesday would decrease.
The remainder of the week is a bit tricker to forecast, as the area will remain close to the border between Canadian high pressure to our north and more unsettled and unstable conditions to our south. It continues to appear that we will remain on the northern side of this boundary . thus have kept the forecast mainly dry to finish out the work week . however this may change if the boundary were to shift northward into our forecast area. Higher confidence in dry weather in the northern part of our CWA, slightly lower confidence in dry weather over southern VT.
AVIATION /08Z SATURDAY THROUGH WEDNESDAY/. Through 06Z Sunday . VFR conditions with light and variable winds are expected to prevail through much of the next 24 hours. The only exception to this will be some patchy IFR/LIFR fog at KSLK and possibly at KMSS this morning with temperatures approaching their crossover values. Any fog that forms this morning will quickly lift after 12Z with just a few to scattered clouds hovering between 6,000 and 10,000 ft throughout the day. Some diurnal convection is expected across the higher terrain but the upper level flow will push these showers away from our forecast terminals.
Sunday: VFR. NO SIG WX. Sunday Night: Mainly VFR, with local MVFR possible. NO SIG WX. Monday: Mainly VFR, with local MVFR possible. Slight chance SHRA, Slight chance TSRA. Monday Night: VFR. Slight chance SHRA. Tuesday: VFR. Likely SHRA, Chance TSRA. Tuesday Night: VFR. Slight chance SHRA, Slight chance TSRA. Wednesday: Mainly VFR, with local MVFR possible. Chance SHRA, Chance TSRA.
