Area Forecast Discussion National Weather Service Burlington VT 1010 PM EDT Sun Jul 24 2022 .SYNOPSIS... Showers and thunderstorms are expected to continue tonight as a cold front crosses the North Country. The threat for severe thunderstorms continues through early morning, flash flooding is also a concern into Monday morning. A pattern shift to drier and cooler weather is still likely by Monday evening. && .NEAR TERM /THROUGH MONDAY/... As of 958 PM EDT Sunday...A new severe thunderstorm watch has been issued for all of Northern New York, as well as Grand Isle, Franklin, Lamoille and Chittenden Counties in Vermont until 5 AM. We will also continue to have a threat for flash flooding in very heavy rain, and especially in areas that see multiple storms pass through the area. Previous discussion follows. Overall setup as of Sunday afternoon features an anomalously moist air mass overhead with precipitable water values expected to climb to 1.75 to 2 inches by this evening. The strong moisture advection is courtesy of a developing 45+ knot southwesterly low-level jet tapping into a ribbon of Gulf of Mexico-sourced moisture. With temperatures climbing into the mid 80s to low 90s, between 250 and 1000 J/kg CAPE is analyzed over the area this afternoon. Strong flow in the mid and upper- levels supports an environment conducive to organized convection. In addition, relatively strong 0-3 km SRH values indicate rotating updrafts are possible in any storms that do develop. The biggest question with regards to this evening's severe weather threat will be lack of any strong surface convergence/boundary, with the cold front upstream not set to work through until tomorrow morning. Nonetheless, several residual boundaries floating around the area including outflow and lake breeze boundaries, so these may be enough to trigger some thunderstorm development going into this evening. Any thunderstorms that do develop have the potential to contain heavy rain and large hail. We also can't rule out an isolated brief spin up given the strong helicity in the low-levels. As we head into the overnight hours, we begin to lose our better instability and the main threat transitions from a severe weather threat more to a hydro threat. Rainfall this evening into overnight will be moderate to heavy in nature, aided by high moisture values, deep warm cloud layer, and continued instability/deep lift. In addition, boundary parallel flow will also favor training of storms, where multiple heavy showers/storms may go over the same area and could potentially result in some localized flash flooding. Synoptic support both in the lower and upper levels also becomes better overnight, so expecting coverage of showers to blossom with fairly widespread precipitation footprint expected overnight. Showers will generally wind down through the day by Monday, and post-frontal conditions will be a little cooler with highs in the mid 70s to mid 80s. && .SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/... As of 328 PM EDT Sunday...Will have a return to quieter weather for the Monday night through Tuesday night timeframe. Temperatures will actually be slightly below seasonal normals for a change as a ridge of surface high pressure builds over the north country, as well as building heights aloft. Low temperatures will be in the mid 50s to lower 60s with highs reaching the mid 70s to lower 80s, with westerly flow and dry weather. && .LONG TERM /WEDNESDAY THROUGH SUNDAY/... As of 328 PM EDT Sunday...Towards the end of the week, will have a potentially impactful system for the Thursday through Friday timeframe. Dry weather will continue for Wednesday as high pressure begins to slide east of the region. On Wednesday night we'll have a frontal system approaching from the west as a low pressure system lifts well north of the region up into Canada. Better chance for showers and embedded thunderstorms will be on Thursday as the fropa takes place, with showers ending Thursday night. Still a lot of time to look closer at the details, but at this time looks like we could at least see some thunderstorms on Thursday, and we'll continue to monitor potential for severe weather. Will have a strong upper level jet crossing the region, along with upper level shortwave energy. Drier weather will return for next weekend with another ridge of surface high pressure building into the region once again. && .AVIATION /02Z MONDAY THROUGH FRIDAY/... Through 00Z Tuesday...Expect showers to impact most TAF sites overnight, but have continued to leave out mention of thunderstorms at this time. Both ceilings and visibilities will be lowering into the night, eventually arriving at MVFR conditions after 03z Monday. Some spots are expected to fall to IFR conditions, including KMPV and KEFK. Winds will be mainly from the south and south-southwest over the next 24 hours, with gusts in the 15-20 knot range. LLWS is anticipated at most TAF sites after 00z Monday, with winds aloft from the southwest at 40-45 knots. Conditions will gradually improve to VFR at all sites after 12z Monday, and winds will veer to westerly. Outlook... Monday Night: VFR. NO SIG WX. Tuesday: VFR. NO SIG WX. Tuesday Night: VFR. NO SIG WX. Wednesday: VFR. NO SIG WX. Wednesday Night: VFR. Chance SHRA. Thursday: Mainly VFR, with local MVFR possible. Chance SHRA. Thursday Night: VFR. Slight chance SHRA. Friday: VFR.
