Area Forecast Discussion National Weather Service Burlington VT 311 AM EDT Fri Apr 26 2024

SYNOPSIS
High pressure will dominate through Saturday afternoon. Tranquil conditions are expected today, and then becoming increasingly breezy on Saturday. Rain chances return Saturday night into Sunday, with weak disturbances likely to bring hit or miss, off and on shower activity throughout the upcoming week. A cold front midweek could bring a higher chance for precipitation.

NEAR TERM /THROUGH SATURDAY/
As of 310 AM EDT Friday...High pressure will bring light winds, low RHs, and seasonable temperatures. Surface high slides offshore and south winds will maintain warmer overnight lows in the mid 20s to mid 30s. South flow increases with gusts up 20 mph Saturday afternoon that will warm us into the 60s. Clouds and showers approach from the west late Saturday evening.

SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY/
As of 310 AM EDT Friday...Deamplifying shortwave trough embedded within a larger area of upper ridging crosses our CWA overnight Saturday, pushing a warm front through and advecting a considerably more moist air mass than we have gotten used to in recent days. Both the GFS and NAM are in good agreement with a north-south oriented plume of 1 inch PWATs advecting eastward during the evening into overnight hours, replacing the 0.3 inch PWATs out ahead of it. To put in perspective how dramatic that is, we go from the 10th percentile to the 90th percentile of SPC PWAT sounding climatology for the Albany, NY upper air site. Forecast soundings indicate some steep mid-level lapse rates and elevated instability, so a few rumbles of thunder overnight are not out of the question particularly across northern NY. It does look like the bulk of the rain should fall during the overnight hours, with the rain becoming more showery and scattered in nature during the day on Sunday. It is worth noting that dew points on Sunday will rise into the 50s to even near 60, especially across the St Lawrence Valley and west of the Adirondacks in northern NY. With a bit of sunshine, temperatures would easily rise into the upper 60s or low 70s. As for Vermont, we start out Sunday with dew points in the 40s but 50s dew points will also overspread the state by mid day into the afternoon hours. This would result in a few hundred joules of CAPE, so a few rumbles of thunder are not out of the question mainly across our northern zones. While there would be rain drops to dodge on Sunday, it would not be a washout either. The uptick in humidity and possible rumbles of thunder would serve as a reminder that summer is not too far away. Overall temperatures will be on the slightly warmer than normal with highs on Sunday in the mid 60s to low 70s, except cooler across the Adirondacks and northeast Vermont. Overnight lows will generally be in the 40s to low 50s.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/
As of 310 AM EDT Friday...The upper level pattern for the first part of the long term forecast involves pieces of weak shortwave energy embedded within a larger ridge axis slowly shifting eastward from the Appalachia into the eastern seaboard. Model guidance has generally trended cooler for the highs on Monday given the abundance of cloud cover and northerly or northeasterly flow. Tuesday high temperatures look to be considerably warmer across northern NY and the Champlain Valley, but cooler east of the Green Mountains. While southerly flow out ahead of an advancing cold front should send highs for the former into the mid 60s to near 70, highs for the latter could struggle to make it out of the 50s. In addition, the cold front that is expected to cross the CWA sometime on Tuesday should provide the best chance for more widespread thunderstorms. At this time, severe weather is not expected but some stronger storms cannot be ruled out, particularly across northern NY into the Champlain Valley. Following the cold frontal passage, partial sunshine should return sometime mid week although blue bird days like we experienced recently might be a challenge given the northern stream jet energy remains fairly active near the international border. It is also worth noting that the CPC 8-14 day temperature outlook has trended from probabilities favoring above normal temperatures to near normal. For reference, typical highs for the first days of May across North Country are in the low to mid 60s.
Given the forecast uncertainty, have largely stuck to a blend of guidance for middle of next week.

AVIATION /07Z FRIDAY THROUGH TUESDAY/
Through 06Z Saturday...Strong high pressure will maintain all VFR with no clouds or fog. Winds will follow tertiary flow patterns with light easterly drainage flows for BTV/RUT and calm conditions elsewhere overnight. A weak lake breeze is likely after 13Z so expect easterlies at PBG with light westerly winds for BTV. Upslope flow pattern after 13Z will drive light westerly for RUT.

Outlook...

Saturday: VFR. NO SIG WX.
Saturday Night: Mainly VFR, with local MVFR possible. Chance SHRA.
Sunday: Mainly MVFR, with areas VFR possible. Chance SHRA.
Sunday Night: Mainly MVFR, with areas VFR possible. Chance SHRA.
Monday: Mainly MVFR, with local VFR possible. Slight chance SHRA.
Monday Night: Mainly VFR, with areas MVFR possible. Chance SHRA.
Tuesday: Mainly MVFR, with local IFR possible. Likely SHRA, Slight chance TSRA.
