Area Forecast Discussion National Weather Service Burlington VT 1047 PM EDT Sun Mar 29 2020
SYNOPSIS. Deep low pressure over the Great Lakes region this afternoon will slowly track across the Northeast through Monday with periods of rain and some higher elevation snow possible. Some showers linger into early Tuesday morning, but drier conditions are generally forecast for the rest of the week along with near normal temperatures.
NEAR TERM /THROUGH MONDAY NIGHT/. As of 1042 PM EDT Sunday . Steep mid-level lapse rates of 7-7.5 C/km and strong forcing ahead of approaching closed low over the northern Great Lakes contributed to several rounds of moderate to briefly heavy showers this evening, along with some embedded thunderstorms. Elevated instability was limited - generally less than 500 J/kg, but sufficient for numerous reports of small (pea-sized hail) aided by very low freezing levels. Also had one report of severe hail around 530pm in southern St. Lawrence County, associated with a long-lived thunderstorm and small- scale bow echo. The more significant activity has pushed ewd into NH/ME, but a few lingering showers are possible overnight. Thermal profiles may support a rain/snow mix along and east of the Green Mtns. Also, some spotty freezing rain is possible across the higher elevations, and have updated the REC forecast accordingly.
Monday morning will start generally dry across the region, but conditions will quickly turn awful as the aforementioned low pressure system tracks from north of Lake Ontario eastward to the New England coastal waters Monday night. As the low passes overhead, showers will once again become widespread from mid-morning through the day with some snow mixing in at the higher elevations and across eastern VT in the afternoon and likely down to the valley floor after midnight. The high peaks could see a couple inches of accumulation, while the valleys a coating to an inch or so.
SHORT TERM /TUESDAY THROUGH TUESDAY NIGHT/. As of 324 PM EDT Sunday . The main upper low finally moves away Tuesday, though we'll remain under cyclonic flow. This will lead to drier conditions as we lose deep moisture; the result will be just a few snow/rain showers possible Tuesday, mainly over the higher terrain. Clouds will gradually decrease, especially late in the day and into Tuesday night, and expect partly cloudy conditions to dominate by early Wednesday. Tuesday's high temperatures will be in the lower to mid 40s, followed by lows in the mid and upper 20s Tuesday night.
LONG TERM /WEDNESDAY THROUGH SUNDAY/. As of 324 PM EDT Sunday . Dry weather will persist through the middle of the week as surface low pressure skirts to our south while upper troughiness persists over the North Country. The southern surface low will stall over the western Atlantic, allowing moisture to rotate westward into New England Thursday into Friday. Guidance continues to differ on whether or not precipitation associated with this moisture will make it into our region; the ECMWF and CMC say yes while the GFS weakens and dissipates moisture across New Hampshire before any appreciable precipitation gets here. The model differences continue into the weekend as the GFS is faster with our next system, a cold front which will move eastward through the Great Lakes as its parent low traverses across central Ontario/Quebec. The GFS and CMC bring precipitation associated with this front in late Saturday-Saturday night, while the ECMWF is much slower, holding it off until almost Monday. Regardless, temperatures will warm into the 50s ahead of the front as we finally see some ridging aloft. Overnight temperatures will be marginally cold enough that some spots, particularly in the higher elevations, could see some snow.
AVIATION /03Z MONDAY THROUGH FRIDAY/. Through 00Z Tuesday . Busy start to the period with thunderstorms ongoing at RUT and moderate showers at BTV. At MPV it was a close call for lightning as well, with convection holding together better than previously expected. At all three VT sites, conditions should bounce between MVFR and VFR depending on the intensity of rain with ceilings close to 3000 feet overall. In NY, some scattered showers will prevail with VFR conditions, although MSS ceilings are still MVFR, through 06Z. After these showers move through, a brief period of low level wind shear at MSS is anticipated with a punch of dry stronger mid-level air. Generally at all sites a trend towards VFR is expected after 05Z in northern NY and after 8 or 09Z in VT, followed by showers returning in the afternoon with widespread MVFR and some IFR possible with lowering ceilings.
Monday Night: Mainly MVFR, with local IFR possible. Likely SHRA, Chance SHSN. Tuesday: Mainly VFR, with local MVFR possible. Slight chance SHSN. Tuesday Night: VFR. NO SIG WX. Wednesday: Mainly VFR, with local MVFR possible. NO SIG WX. Wednesday Night: Mainly MVFR, with local IFR possible. NO SIG WX. Thursday: Mainly MVFR, with local IFR possible. Chance SHRA. Thursday Night: Mainly MVFR, with areas IFR possible. Slight chance SHRA. Friday: Mainly MVFR, with local IFR possible. Slight chance SHRA.
