  (on/off)  Help NOTE: mouseover dotted underlined text for definitionFxus61 kbtv 202055 afdbtv area forecast discussion national weather service burlington vt 355 pm est Wed feb 20 2019 Synopsis Snowfall will develop during the evening hours tonight as a warm front lifts through the region. Snowfall amounts of 3 to 5 inches will be common across the green mountains and eastern vermont while the rest of the area will generally see 1 to 3 inches of snow. Temperatures will warm through the overnight period which may allow for some sleet to mix in with the snow across southern vermont and portions of northern new york. After highs warm into the upper 30s to mid 40s on Thursday, temperatures will return back to normal values for Friday and Saturday before another, and more potent, warm front lifts northward and raises temps into the mid to upper 40s for Sunday. Ahead of this front, a a mix of snow, freezing rain and sleet will be seen as temperatures are slower to cool at the surface compared to just off the surface. Near term through Thursday night As of 348 pm est Wednesday... A low pressure system located over virginia will continue to track northeastward heading into Thursday. As this happens, a warm front will continue to lift northward toward the north country. Snowfall ahead of this warm front will move into southern vermont and portions of northern new york between 6 and 8 pm and into central and northern vermont between 8 and 10 pm. Snowfall amounts will be greatest across the eastern half of vermont (from the green mountains eastward) with greatest frontogenetic forcing being closer to the low pressure system. Snowfall amounts will range from 3 to 5 inches across eastern vermont with the rest of the forecast area seeing between 1 and 3 inches. As warmer air begins to filter in aloft behind the warm front, there is the possibility for some sleet to mix in with the snow. Warmer air aloft will begin to partially melt and refreeze as it falls below the melting later across southern vermont and portions of northern new york after midnight tonight. Based on the latest high-res guidance, they are trending toward a "colder" solution which would minimize the potential for mix but still looks favorable for some locations to see some sleet mix in. Temperatures for the large part will either be steady-state or warming throughout the night with increasing warm air advection. In addition, gusty southerly winds will develop toward morning which will aid in mixing down warmer air. These gusty winds won't be particularly strong but will range between 20 and 35 mph. We get dry- slotted pretty quick Thursday morning which will allow much of the precipitation to end toward sunrise but a good westerly jet should help showers linger on the western slopes of the adirondack mountains as well as the northern green mountains. Thermal profiles would support a mix of rain and snow which would lean towards more rain during the late morning and afternoon hours and trend toward mostly, if not all, snow as a cold front slides through late Thursday. High temperatures on Thursday will range from the upper 30s to mid 40s with lows dropping into the 20s. Short term Friday through Saturday As of 353 pm est Wednesday... Friday starts out mostly dry with some lingering upslope mountain snow showers under light northwest flow. High pressure builds during the morning and the weather should be fairly pleasant across the north country with temps near normal. Highs will be in the mid 30s Friday increasing to the mid to upper 30s Saturday. Lows will be slightly above normal with temps only in the low to mid teens. Long term Saturday night through Wednesday As of 353 pm est Wednesday... The quiet weather is short lived as a system will push into the great lakes region Saturday night and will bring widespread precipitation to the north country Sunday through Monday. A vertically phased low pressure system will develop off the lee edge of the rockies and push northeast over the great lakes bring continued warm southerly flow. Based on thermal profiles and soundings there's going to be some dry air in the lower levels that should lead to a fair bit of wet |
bulb cooling initially. That should keep the precip type as all snow for much of the evening before changing over to mixed precip with some snow pellets and a 2-3 hour window of some freezing rain before the temperatures warm well above freezing late Saturday night into Sunday morning. Rain should continue through much of the morning Sunday before a mid level dry slot brings a brief lull in the action Sunday evening. Behind that a cold front will slowly drop temperatures and precip will start again as snow Sunday night into Monday morning. Sunday afternoon there's a strong low level jet that noses into the saint lawrence valley and thats going to potentially do two things, one mix some stronger gusts into the saint lawrence, and two shadow the champlain valley. So total precip will likely be significantly impacted by orographic effects. High pressure then settles back in across the region Monday night and Tuesday with another shortwave bringing some precipitation mid week however temps should be cold enough to mitigate any mixed precip concerns. Based on the latest suite of guidance i'm not real bullish on any flooding threats outside any river locations that are not currently jammed with no channels. 24 hour rainfall totals appear to be on the order of a half to three quarters of an inch and absent quite a bit warmer temperatures I dont see significant snow melt running off. So there shouldn't be enough water added to the basins to lift and break ice. That said, we'll continue to monitor for any changes and specifically for those locations that already have an ice jam in place. Aviation 21z Wednesday through Monday Through 18z Thursday...VFR conditions will persist through the remaining afternoon hours with wind gradually increasing to around 10 knots from the south. Between 01z and 03z, snowfall will begin to move into TAF sites with ifr visibilities and MVFR ceilings expected with the falling snow. Snow will taper off quickest across valley locations with higher elevations like kslk and kmpv likely holding onto precipitation a bit longer. There will be some sleet mixing in with the snowfall over kslk after midnight but it looks like precipitation will taper off prior to TAF sites seeing a transition to some light rain. Winds will become gusty from the south southwest Thursday morning with winds gusting between 18 kt and 22 kt. Ceilings will trend back towardVFR Thursday afternoon. Outlook... Thursday night:VFR.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
