Area Forecast Discussion National Weather Service Burlington VT 142 PM EDT Sun Apr 18 2021

SYNOPSIS. Another mostly cloudy day with a few spot showers are possible across the region with near normal temperatures. A similar scenario is on tap for Monday, but with slightly warmer temperatures. The next large scale system arrives on Wednesday with a widespread precipitation event likely, ending as some mountains snow showers on Thursday. Temperatures are above normal for Tuesday into Wednesday, but trend below normal by Thursday on brisk northwest winds.

NEAR TERM /THROUGH MONDAY/. As of 134 PM EDT Sunday . We've now transitioned to the expected convective shower activity across northern New York. Several cells are present, so expect off and on showers, especially in the Adirondacks, where this will be focused. As activity heads east into the Champlain Valley, we should see showers decrease in areal extent. The forecast is on track, but did reduce daytime high temperatures a couple degrees given abundant clouds and showers. Have a great day!

Previous Discussion . Water vapor showing cyclonic northwest mid/upper lvl flow conts acrs the ne conus as deep closed circulations continues to rotate over the North Atlantic. A very weak embedded 5h vort, combined with a ribbon of enhanced 850 to 700mb moisture streaks acrs our northern NY into southern VT this morning, which may produce a few spot showers. Radar is showing some light development of the dacks, as predicted by NAM based solutions, so have continued with schc/chc pops for this area. Otherwise, temps warm a degree or two from yesterday, supporting highs upper 40s to mid/upper 50s areawide. Tonight, soundings show variable degrees of moisture, so anticipating multiple layers of clouds present. Temps with clouds wl stay on warmer side of guidance values, mainly mid 30s to lower 40s.

For Monday, we have a little of everything, such as a little instability, a weak 5h vort in the flow aloft, and a little better mid lvl moisture, resulting in a little better chance for a few showers. The highest chc pops extend along and mainly north of a SLK to BTV to LEB line. Have noted soundings show 200 to 350 j/kg acrs northern NY into VT, while sfc to 800 mb lapse rates >7.0 C/km, as weak vort travels along the international border btwn 15-21z. Have continued to mention chc pops attm, as available moisture and deep synoptic scale lift is limited. Have not mention thunder, but expect a convective nature to precip activity on Monday aftn. Progged 925mb temps are btwn 6-8c, so have bumped temps into the upper 50s to mid 60s.

SHORT TERM /MONDAY NIGHT THROUGH TUESDAY/. As of 414 AM EDT Sunday . Quiet conditions begin the period Monday evening before a decaying cold front approaches from the west for the latter half of the night. Weak forcing and little moisture convergence along the boundary will preclude any real significant precipitation from falling, but have noted a slight uptick in model QPF so will highlight some low chance PoPs across northern New York, and a slight chance eastward Tuesday morning. Drier conditions return for Tuesday afternoon behind the frontal passage with temps in the 50s across western and northern areas, and 60s central/south.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. As of 414 AM EDT Sunday . Focus for the extended period continues to be the potential for another moderate rain event Wednesday followed by upslope rain/snow showers Thursday into Friday.

Little overall change in this mornings 00Z NWP guidance synoptically with the main features continuing to be a digging upper trough over the northern Plains and developing surface low over the Ohio Valley Tuesday night which look to track through the Northeast on Wednesday. Still some uncertainty in the exact track of the surface low, which will play a large role in how far the aforementioned frontal boundary from Tuesday moves back north as a warm front and subsequent boundary layer temps that follow. Still doesn't appear to be much of a convective threat with generally moist adiabatic profiles in the forecast soundings, but good mid/upper level dynamics and a strong frontal zone will enhance precipitation across the region with early rainfall estimates through Wednesday night in the 0.5-1" range.

Heading into Thursday and Friday, guidance continues to point to upstream blocking slowing the northeastward progression of the system as it moves towards the Gulf of St. Lawrence. Conditions continue to look favorable for WNW upslope flow supporting scattered to numerous valley rain and mountain snow showers possibly lingering into Friday morning. Thereafter a brief mid/upper level ridge will bring drying conditions for Friday night into Saturday before another system approaches for Sunday.

AVIATION /18Z SUNDAY THROUGH FRIDAY/. Through 18Z Monday . Mainly VFR conditions with localized pockets of 2500 ft agl ceilings. Scattered rain showers are developing over northern New York, which are small in size, but covering a modest area. Intermittent showers possible at KMSS KRUT, and then most likely at KSLK through 00Z. Scattered showers transition towards KPBG and KBTV from 00Z to 03Z, and then dissipate. Around 03Z to 10Z, could be some patchy fog at KMPV, KSLK, and KRUT where clouds may scatter out. Otherwise, northwest winds become light and variable with ceilings remaining 2500-3500 ft agl. After 12Z, ceilings should lift and fog should dissipate. Scattered showers develop again after 15Z Monday.

Outlook .

Monday Night: VFR. Slight chance SHRA. Tuesday: VFR. Slight chance SHRA. Tuesday Night: VFR. Chance SHSN, Slight chance SHRA. Wednesday: Mainly VFR, with areas MVFR possible. Definite RA, Chance SHRA. Wednesday Night: Mainly MVFR, with local VFR possible. Likely RA, Chance SHRA, Chance SHSN. Thursday: Mainly MVFR, with areas VFR possible. Chance SHRA, Chance SHSN. Thursday Night: Mainly VFR, with areas MVFR possible. Chance SHSN, Slight chance SHRA. Friday: Mainly VFR, with areas MVFR possible. Slight chance SHRA.
