088 FXUS61 KBTV 011735 AFDBTV Area Forecast Discussion National Weather Service Burlington VT 135 PM EDT Sat Jun 1 2024 .SYNOPSIS... A warming trend is expected through the weekend into early next week with many places warming into the 80s each day. Dry weather is also expected to continue with high pressure expected to remain entrenched across the region. As it stands, the next chances for any appreciable rainfall aren`t until Thursday. && .NEAR TERM /THROUGH SUNDAY NIGHT/... As of 135 PM EDT Saturday...Main change to the forecast for this afternoon was to decrease wind gusts as mixing is not looking as ideal as previously thought, and winds aloft will be weakening through the afternoon. Highs remain on track for mid 70s to low 80s. Moisture will begin to return to the region tonight in the form of clouds which should help moderate temperatures a bit and keep them warmer than the previous few nights. The warming trend is expected to continue into Sunday with most locations warming into the 80s. Again, dewpoints are expected to tank in the afternoon with plenty of dry air aloft mixing down to the surface. Although it`ll be warm, the lower humidity values should make it feel quite comfortable outside. && .SHORT TERM /MONDAY THROUGH MONDAY NIGHT/... As of 318 AM EDT Saturday...North Country Chamber of Commerce weather continues for the short term fcst with continued mostly dry conditions and comfortable temps. Cannot completely rule out a very isolated <5% coverage of a shower on Monday aftn over the higher trrn associated with llvl east/northeast flow. However, forcing/moisture is minimal and instability parameters show <350 J/kg of sfc based CAPE. Progged 925mb temps near 20C, adding at least 10C, given dry air and decent mixing supports highs well into the 80s most locations. However, humidity values remain in the comfortable range as drier air aloft mixes toward the sfc during the aftn hours. Based on dry air and lingering sfc high pres, did trim lows at SLK/NEK by several degrees with values mid 40s to near 60F for Monday night. && .LONG TERM /TUESDAY THROUGH SATURDAY/... As of 318 AM EDT Saturday...Large scale pattern amplification occurs for midweek with an omega type structure to the mid/upper lvl height fields. Initially we are in the sweet spot for continued dry conditions with comfortable temps for Tues into Weds. Highs generally in the upper 70s to mid 80s for midweek, supported by progged 925mb temps in the 19-21C range. Meanwhile, lows should drop back into the 50s to lower 60s with comfortable humidity values. The long term challenge is timing large scale pattern change toward the end of the week into next weekend and potential for prolonged period of unsettled wx to develop with cooler temps. Guidance has been struggling with development of deep/closed cyclonic circulation over the northern Plains and how quickly east this system tracks for late week. Latest trends have been for a slower arrival to height falls and potential precip with greatest probability of measurable precip arriving late Thurs into Friday. Ensemble data continues to support a rather large spread in potential solutions, so for now have cut back on likely pops offered by the NBM and have chc wording, which wl increase once timing becomes clearer. In addition, as mid/upper lvl trof develops toward next weekend, cooler air at all levels develops, along with more clouds results in cooler daytime high temps, but overnight lows remain on the milder side. Highs mostly in the 70s with lows upper 50s to mid 60s for late next week, with pops in the 30-45% range. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... Through 18Z Sunday...VFR conditions will persist through the period with cirrus clouds above 20,000 feet becoming SCT/BKN overnight into Sunday and lowering to around 15,000 feet by midday. NNW winds at 6-8kts this afternoon except locally ESE at KPBG, will trend back to light and variable after 00Z, then 4-6kts from the WSW after 14Z Sunday. Outlook... Sunday Night: VFR. NO SIG WX. Monday: VFR. NO SIG WX. Monday Night: VFR. NO SIG WX. Tuesday: VFR. NO SIG WX. Tuesday Night: VFR. NO SIG WX. Wednesday: VFR. Slight chance SHRA. Wednesday Night: VFR. Slight chance SHRA. Thursday: Mainly VFR, with local MVFR possible. Chance SHRA. && .BTV WATCHES/WARNINGS/ADVISORIES... VT...None.
