The episode as NWS ALY wrote it up.
A cold front crossed through the area during the afternoon and evening hours on Tuesday, June 13th. With a warm and humid air mass ahead of the front, some showers and thunderstorms developed across the area. A few of the storms became severe in Dutchess and Columbia counties, mainly producing damage to trees and power lines.

Area Forecast Discussion National Weather Service Albany NY 920 AM EDT Tue Jun 13 2017 .SYNOPSIS... A warm and muggy air mass will continue to be in place today, although a cold front will be crossing the region with a chance for some passing showers and thunderstorms. Behind the cold front, cooler and less humid air will move into the region for tomorrow into Thursday. Another frontal system will approach for Friday into the weekend, with the chance for showers and thunderstorms. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... As of 900 AM EDT...12Z soundings are in as slower progression of the upstream frontal boundary may result in a couple of items. First, heat index values for our western New England counties may get close to the criteria of 95F for the second day as latest forecast dewpoints are expected to fall just short. Second will be convective upstream trends. Leading edge of the showers/storms did quickly dissipate as they moved ashore from Lake Ontario. 12Z sounding does show several cap layers in partial due to broad ridge axis across the region and the warmer temperatures aloft. With a slower progress of the frontal zone, additional heating should commence for increase surface based instability. However, overall shear parameters lag behind a bit and best upper jet support remains well north of the St Lawrence Valley. HRRR and NAM3KM reflectivity forecasts support these ideas with isolated to scattered convection with the best concentration mainly south of I90. DCAPE from the 12Z soundings are between 700-900 J/KG so any precip loading within the PWATS of around 1.75" could produce a wet microburst. We will continue to monitor as SPC keeps the southern half of the region within a 'marginal risk'. Prev Disc...Our region remains on the northern fringe on a flat upper level ridge located across the eastern part of the CONUS. High heights and warm temps aloft (850 hpa temps around 16 degrees C) have been allowing for very warm temperatures over the past few days. A cold front is currently upstream of the region over the eastern Great Lakes and will be passing through the area between the mid morning and late afternoon hours from northwest to southeast. Some showers and thunderstorms are already seen on MRMS imagery across Lake Ontario and these are starting to slide eastward towards the Adirondacks for this morning. Showers and thunderstorms look limited for northern areas due to a mid-level cap in place and earlier passage of the boundary. However, southern areas (mainly south of I-90) will see a better chance for showers and thunderstorms (primarily during the early to mid afternoon hours) due to more instability in place. Latest model soundings are showing more instability than previous runs for Albany southward towards Poughkeepsie, with over 2000 J/kg. Some model soundings suggest even as much as 4000 J/kg near Poughkeepsie based on dewpoints in the upper 60s and max temps in the low 90s, although this could be slightly overdone, as afternoon mixing may allow for the boundary layer to be slightly less moist than what this is showing, which would keep CAPE values a little lower. Despite the instability available, 0-6 km bulk shear values are still fairly weak (just barely 30 kts) and the forcing is primarily just from the surface boundary and a weak mid-level impulse, as the best upper level dynamics will be located over southern Canada. Still, enough things may come together for an isolated strong to severe t-storm today for the Catskills, mid- Hudson Valley or NW CT. SPC has placed the southern portion of the region in a marginal risk for severe thunderstorms, with the main threat being gusty winds. Both the 3km NAM and 3km HRRR have different ideas of how this convection will play out and seem to be changing with every run. This gives less confidence regarding the exact placement, timing and strength of convection today, but multi-cell clusters or small lines of storms are certainly possible for southern areas later today. Heavy rainfall would be possible with any storm as well, as PWAT values are rather high (almost up to 2.00 inches across southern areas by late today) and high freezing levels (around 15 kft) would promote warm rain processes. There is still enough flow though that any t-storm should be fairly brief in duration and the progressive nature of the boundary will aid in keeping the threat for extended heavy rainfall down as well. It looks warm once again, especially for southern areas, where the front won't be crossing until later in the day. Highs will reach the mid to upper 80s for valley areas, with 70s to low 80s for the higher elevations with a partly to mostly cloudy sky. Humidity levels will stay high ahead of the front with dewpoints well into the 60s. && .SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/... As the boundary moves across the area late today, a return to drier, cooler and less humid air will be underway, as surface high pressure builds into the region from southern Canada for tonight. Any showers or t-storms will end by 9 or 10 PM, and skies will gradually clear out from north to south tonight. Temps will fall into the low 50s to low 60s for most spots, with dewpoints quickly coming down as well. Sunny and pleasant weather with low humidity is expected both Wednesday and Thursday, although some clouds will start to increase late Thursday ahead of the next system. Highs will be in the 70s both days, with dewpoints in the 40s on Wednesday and 50s on Thursday. Lows on Wed night will be cool thanks to clear skies and light winds, with min temps in the 40s to low 50s. The next storm system will be approaching from the Great Lakes Thursday night with increasing clouds. Depending on its exact speed, some showers may move into western areas by late in the night, although this is still uncertain. Lows on Thursday night will mainly be in the 50s. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... Guidance is in agreement the longwave pattern across the northern CONUS should be nearly zonal as we head into the weekend. Ridging along the east coast is expected to continue to weaken as it shifts farther eastward. Looking at an active northern stream with a trough developing across the eastern CONUS by early next week as short waves rotate about an upper level low that develops over Hudson Bay Canada. The weather will be unsettled with boundaries and short waves moving across the region. The model differs with the timing of these features so have mainly chance pops through the period. However on Friday, have gone with higher likely pops for showers as a warm front gradually approaches from the west. With the warm front expected to remain to our west have below normal temperatures for Friday. Elevated instability is expected to move across the region Friday night so have added the mention of thunder. Over the weekend we should be in the warm sector thus warmer along surface-based instability and the threat for thunderstorms especially during the daytime. && .AVIATION /13Z TUESDAY THROUGH SATURDAY/... The region is on the northern fringe of a flat upper level ridge with a cold front on the approach from the Great Lakes region. The cold front will gradually press southward across the region today with isolated to scattered showers and thunderstorms expected. The better chances for the storms will be at KPSF and KPOU where there will be greater instability. Have addressed the threat for convection with VCSH in the KGFL and KALB TAFs and with a TEMPO group for thunderstorms in the KPSF and KPOU TAFs. High pressure will build in from the north behind the boundary. Winds will become mainly westerly this morning; the exception will be at KGFL where a northeast flow is expected due to local terrain influences. Winds will be on the increase during the day eventually shifting to the northwest to north with the passage of the cold front. Outlook... Wednesday Night: No Operational Impact. NO SIG WX. Thursday: No Operational Impact. NO SIG WX. Thursday Night: Moderate Operational Impact. Chance of SHRA. Friday: High Operational Impact. Likely SHRA. Friday Night: Moderate Operational Impact. Chance of SHRA...TSRA. Saturday: Moderate Operational Impact. Chance of SHRA...TSRA. Saturday Night: Moderate Operational Impact. Chance of SHRA...TSRA. Sunday: Moderate Operational Impact. Chance of SHRA...TSRA. && .FIRE WEATHER... A cold front will be moving across the region today. RH values will only fall to 50 percent this afternoon with some passing scattered showers and thunderstorms thanks to the cold front. West winds will become northwest at 5-10 mph. Not everywhere will see rainfall, but any spot that sees a thunderstorm could see a locally heavy downpour. Behind the cold front, RH values will fall to 30-35 percent on Wednesday afternoon with north winds of 5 to 10 mph with no chance for precipitation. The next chance for widespread rain showers will be Friday into Saturday. && .HYDROLOGY... No widespread hydrologic issues are anticipated over the next several days. Recent dry weather has allowed elevated river levels to return closer to normal flows. A cold front will be crossing the region today, which will allow for a a chance for scattered showers and thunderstorms. These rivers won't have a big impact on main stem rivers and streams, but brief heavy downpours will be possible within any thunderstorm. Although flash flooding is not anticipated, poor drainage and urban areas could briefly see locally high water during any thunderstorm. Dry weather will then return once again for Wednesday into Thursday. The next chance for showers and thunderstorms will be Friday into the weekend with another frontal system moving through the area.
