Area Forecast Discussion National Weather Service Burlington VT 341 PM EDT Sat Mar 28 2020

SYNOPSIS. Deep low pressure over the central Plains will dominate the North Country's weather over the next several days as it slowly tracks through the Great Lakes and across the Northeast. Periods of rain will develop late tonight and continue through Monday night with some higher elevation snow possible. Some showers linger into Tuesday, but drier conditions are generally forecast for the rest of the week along with near normal temperatures.

NEAR TERM /THROUGH SUNDAY NIGHT/. As of 341 PM EDT Saturday . Very little overall change from the previous forecast idea as models remain in good consistency in regard to the synoptic setup with some minor differences in the more mesoscale details. Current satellite imagery tells the story showing deep low pressure over the central plains with a stream of rich GOMEX moisture riding northeast into the Ohio Valley then eastward through the mid-Atlantic along a warm frontal boundary. As the system slowly trudges northeast towards the Great Lakes tonight, the warm front will begin lifting into the northeast with widespread precipitation developing over the forecast area after midnight from southwest to northeast. Latest trends in the guidance is for the onset of precip to be most delayed across central/northeast VT until after sunrise, which is good because it will limit the threat of any freezing precipitation as overnight temperatures will fall close to freezing there. Elsewhere, with thick cloud cover and a strengthening south-southeasterly low level jet temps will initially fall into the mid 30s to low 40s, then begin rising during the pre- dawn areas supporting rain as the dominant ptype.

Widespread rain continues through mid-day Sunday but will taper to showers during the afternoon ahead an occluded front. During this period, the 925mb jet amplifies to 50-60kts over the downslope regions of the northern Greens and Adirondacks and though the lowest levels are fairly saturated, enough mixing appears likely to support winds gusting as high as 40 mph until the occlusion passes during the evening hours. In addition, ahead of the occlusion models are indicating weak surface instability of a couple hundred J/kg develops, mainly across northern New York which could support some isolated thunder. Have included a slight chance through sunset.

Finally for Sunday night, the occlusion shifts east of the region with a mid-level dry slot working in ahead of a cold front which will arrive Monday as the low pulls north of Lake Ontario. Any evening to early overnight showers should decrease in areal coverage for the night with portions of eastern Vermont and the Adirondacks possibly seeing some light snow and perhaps a dusting of accumulation as temps fall into the 30s.

SHORT TERM /MONDAY THROUGH MONDAY NIGHT/. As of 341 PM EDT Saturday . The aforementioned low pressure system continues to plague the North Country on Monday as it tracks from north of Lake Ontario Monday morning 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 night with some snow mixing in at the higher elevations. Highs will be in the mid 40s, and lows in the low to mid 30s.

LONG TERM /TUESDAY THROUGH SATURDAY/. As of 341 PM EDT Saturday . Much of next week is looking showery with near normal temperatures as upper-level troughiness will persist through the period. The associated cold pool aloft will keep a slight chance/low chance of rain/snow showers through at least Wednesday. Surface low pressure will remain to our south Wednesday- Thursday as it moves off the Mid- Atlantic coast and then stalls well south of Nova Scotia into the end of the week. The GFS, CMC, and ECMWF all indicate a band of precipitation stretching northward along an inverted trough, pushing westward from the Canadian Maritimes, but the exact timing and the amount of westward progression is in question. Both the CMC and ECMWF bring it into the North Country, while the GFS washes it out in New Hampshire while a cold front scoots in from the west. Given the model differences, have stayed with chance PoPs through the end of the week. Friday looks to be the warmest day as we finally get into ridging aloft and south flow ahead of the aforementioned cold front.

AVIATION /20Z SATURDAY THROUGH THURSDAY/. Through 18Z Sunday . VFR conditions and light winds will prevail through this evening with clouds continuing to thicken and lower. Rainfall will move into the North Country between 03Z and 10Z with MVFR ceilings developing as the rain begins to fall. Visibilities will likely be reduced to 3-5SM during the rainfall on Sunday with the potential for some isolated IFR conditions after 12Z. A developing southeast jet will bring the possibility for LLWS to KSLK/KMPV late in the forecast period.

Outlook .

Sunday Night: Mainly VFR, with local IFR possible. Definite SHRA. Monday: Mainly MVFR, with local VFR possible. Definite SHRA. Monday Night: Mainly MVFR, with areas IFR possible. Likely SHRA, Chance SHSN. Tuesday: Mainly MVFR, with areas VFR possible. Slight chance SHRA. Tuesday Night: Mainly MVFR, with areas VFR possible. NO SIG WX. Wednesday: Mainly VFR, with areas MVFR possible. NO SIG WX. Wednesday Night: Mainly VFR, with local MVFR possible. Slight chance SHSN. Thursday: MVFR. Slight chance SHRA.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
