Area Forecast Discussion National Weather Service Burlington VT 128 AM EDT Sat Aug 8 2020
SYNOPSIS. A mostly dry night in store for the North Country under partly cloudy skies. However, a slight chance of showers exist this evening and overnight across southern and central Vermont. Afternoon showers and thunderstorms will be possible Saturday afternoon but will largely be anchored to the higher terrain of the Green and Adirondack Mountains. A lull in shower activity is expected on Sunday but unsettled weather is expected to move back into the region early next week. While temperatures have been cooler over the past several days, we will begin to see a warming trend next week with temperatures approaching 90 degrees early next week.
NEAR TERM /THROUGH SUNDAY/. As of 123 AM EDT Saturday . A few showers have moved across southern Vermont this morning in response to a weak PV anomaly on the leading edge of the upper level trough. Model soundings continue to show a very stable environment in place so these showers will continue to be weak and short lived. Over the western Adirondacks into the St. Lawrence Valley, clear skies have continued with temperatures now within 2 degrees of their crossover temperatures. This should allow some patchy dense fog to develop over the next few hours before lifting shortly after sunrise.
Previous Discussion . The base of an upper level trough will swing through the Northeast tonight, it's surface reflection developing as a deepening low off the coast of New England. This will bring an increase in clouds for most of the North Country this evening, the most dense of which will be located across southern Vermont during the overnight hours. There also exists a chance of showers across south-central Vermont late this afternoon and through the overnight hours as low-level southeast flow ushers in Atlantic moisture. Paired with the passing trough axis aloft and embedded vorticity maxima, large- scale ascent will favor the development of scattered showers despite the lack of surface forcing. The threat of thunder, however, is limited given the lack of daytime instability attributed to the lingering cloud cover across this area. Overall, one tenth of an inch or less of rainfall is expected through Saturday morning. Overnight lows will be a tad warmer than the past couple of nights in the upper 50s/low 60s.
Saturday there exists a chance of isolated/scattered showers and thunderstorms. The better chances will again be across the southern Adirondacks and south-central Vermont. One of the limiting factors will be the dry air situated to the north associated with the lingering surface high pressure. This dry air will be at war with the moist, Atlantic air across southern New England. The 12z NAM guidance suggests that the aforementioned surface low along the New England Coast will deepen and quickly track eastward, pulling away said moisture along with it. This would act to further inhibit storm development for Saturday afternoon and evening. On the other hand, warm air advection and clearing skies will provide diurnally-induced instability. Ultimately, these combined factors will likely lead to isolated terrain- driven showers and thunderstorms. Highs Saturday will again be in the upper 70s/low 80s. Saturday night will be mostly clear and dry as a ridge moves in overhead with overnight lows in the mid to upper 50s.
SHORT TERM /SUNDAY NIGHT/. As of 303 PM EDT Friday . Sunday and Sunday night will feature west to northwest flow aloft over the region. There will be a weak shortwave trough moving through this flow over eastern Canada and this should result in some convection north of the international border Sunday and Sunday evening. At this time expecting most of this to stay out of our area, but there is a small threat for some of this activity to reach our far northern areas late in the day. Have left it out of the forecast for now, but definitely something to keep an eye on. Nevertheless most areas should see a dry day with highs in the upper 70s to mid 80s. Lows Sunday night will be in the upper 50s to mid 60s.
LONG TERM /MONDAY THROUGH FRIDAY/. As of 303 PM EDT Friday . Warming trend starts in earnest on Monday and above normal temperatures are expected for the entire extended period. Highs will be in the mid 80s to lower 90s as ridging aloft develops over the area. With the above normal temperatures and dew points climbing into the 60s there should be enough instability for the development of convection. However, deep layer shear is weak and forcing will be confined to the higher terrain. Going forecast of a slight chance of afternoon and evening thunderstorms looks good. Convection will be pulse in nature and not expecting storms to become strong or severe. The potential for organized convection continues to exist for later on Tuesday. Highs will once again be in the mid 80s to lower 90s and dew points well into the 60s. Frontal boundary will be approaching the Saint Lawrence Valley late in the day and deep layer shear will also be increasing over the top of the frontal boundary and axis of higher instability. This deep layer shear is not strong, but better than Monday and may be just enough to allow for organized convection to develop As a result. still need to keep an eye on the potential for strong to severe storms Tuesday afternoon and night. Like the idea in the forecast for showers likely and a chance of thunderstorms for much of the area and will continue with this idea. Boundary eventually clears the area later on Wednesday and thus looking at the potential for more showers and Thunderstorms across the area as instability develops during the afternoon. Deep layer shear is weaker, but front and instability suggest a continuation of the mention for showers and storms across the area. Starting to see a pattern change later in the week with upper ridging building across the Northeast Thursday into Friday. High pressure building down from Canada suggests northern areas could remain dry with instability across our southern areas for the possibility of some showers and storms. Highs will likely be in the 80s both days with lows in the upper 50s to upper 60s.
AVIATION /06Z 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.
