An upper-level disturbance brought scattered showers and thunderstorms to portions of eastern New York on June 2, 2023, mainly across areas west of the Hudson River. Some of these thunderstorms became severe producing hail up to around 1 inch in diameter and damaging wind gusts downing trees and wires.

NWS Albany, NY wrote its last area forecast discussion before the first event at Jun 2, 9:25 AM EST, 2 hours 28 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Albany NY 1025 AM EDT Fri Jun 2 2023 .SYNOPSIS... An upper level disturbance dropping south out of Canada will bring some clouds, along with the chance for some scattered showers and thunderstorms this afternoon and evening. Cooler temperatures are expected for the weekend into early next week, with some additional showers expected during the week as well. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... As of 1025 AM EDT...Large upper level ridge has retrograded westward and is now centered over lower Michigan. Meanwhile, a an upper level disturbance is located well northeast of the region over Quebec and Labrador and this will be dropping southward towards the region. Visible satellite imagery continues to show fairly clear skies for the morning hours. There have been some passing mid and high level clouds, mainly for northern areas. With strong surface heating already underway, some diurnal cumulus will begin to form over the high terrain over the next few hours. Some signs of convection can already be seen well northeast of the region, with a few thunderstorms already developing south of Quebec City, as well as across the far eastern Gaspe Pennisula of far eastern Quebec. CAMs suggest some showers and thunderstorm activity may initiate across our area by the early to mid afternoon hours. Differential heating may allow the activity to initially form across the high terrain of the Adirondacks, as well as southern Vermont. This activity looks fairly isolated to scattered, but it will be drifting southward. Meanwhile, somewhat more widespread activity looks to occur across northern and eastern New England, as it will be a little closer to a surface boundary and the upper level disturbance. Surface temps have already warmed into upper 70s to low 80s in valley areas and will continue to rise. Max temps should reach the upper 80s to low 90s in valley areas, with low to mid 80s in the high terrain. Surface dewpoints are a little higher than recent days as well, with values reaching the upper 50s to near 60. With the warm and more humid air mass in place, there will be abundant instability in place today. Model guidance suggests SBCAPE values will reach 1500-2000 J/kg across much of the area by the mid afternoon hours. The low-level lapse rates will be rather high due to the strong heating. With the upper level disturbance still quite far away, there won't be much shear this afternoon. 0-6 km bulk shear values will generally be under 20 kts. The strong low-level lapse rates and decent mid level lapse rates (around 6 to 6.5 deg C/km), could allow for some updrafts, but storms will be disorganized and pulse-like in nature due to the lack of shear. As a result, they look to develop and fall apart rather quickly. With the inverted v low-level sounding, there could be some gusty winds as storms collapse. Gusts may wind up in the 30-50 mph range, so they will probably be sub-severe, but a few downed tree limbs and other minor issues can't be ruled out today. Can't rule out some small hail, but no large hail looks to occur today. While some downpours are possible, heavy rainfall doesn't appear to have a flood threat for today. It has been dry over the region over the last few weeks and rainfall is much needed. PWATs aren't excessive and training convection is not anticipated today. While storms won't move too fast, they should develop/die off fairly quickly, so the threat for flash flooding looks very low today. Some brief ponding on roadways can't be ruled out, but that should be the only minor water- related issue today. Showers and thunderstorms may linger into the evening hours, but should start to wane by later in the evening with the loss of daytime heating. && .SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/... Upper cut off low forms in or near eastern New England and low level flow becomes north to northeast as cold advection occurs through Saturday from northern New England. The core of the upper cold pool should be east of our region but some lingering showers are expected through Saturday morning before a gradual break up of the clouds is expected. There should be some sunshine in the afternoon, especially in areas west of the Hudson Valley, with clouds lingering much longer from the Hudson Valley through Western New England. Highs Saturday in the mid 60s to around 70 with some lower 70s in far western areas that will have the most sunshine Saturday. Continued clearing Saturday night and partly to mostly sunny Sunday with the most clouds in western New England, closest to the slowly departing upper low. An isolated shower cannot be ruled out in western New England through Sunday. Highs Sunday in the upper 60s to lower 70s with a few mid 70s in parts of the Hudson Valley along and south of the Capital Region. Partly cloudy to mostly clear Sunday night into early Monday morning. && .LONG TERM /MONDAY THROUGH THURSDAY/... Unsettled weather is expected through the period with below normal temperatures. An upper low that developed along the New England Coast is expected to be moving eastward away from the region Monday. However, short wave energy dropping southward from east of Hudson's Bay is expected to result in the development of another upper level low. This low is expected to be positioned over the Northeast with short waves rotating about it as it lingers over the region. There are some differences in the guidance about how far south and west the broader trough gets. Guidance does indicates this low should shift eastward by the end of the period, however additional short waves maintain a longwave trough over the eastern CONUS. Expecting temperatures to run 5 to 10 degrees below normal with daily highs in the upper 50s to lower 70s and nighttime lows in the 40s to lower 50s. The Climate Prediction Center's 6-10 Day/June 7-11 and 8-14 day/June 9-15 temperatures outlooks favor below normal with the precipitation outlooks near normal. && .AVIATION /14Z FRIDAY THROUGH TUESDAY/... Through 12/SAT...High pressure across the region will weaken and a disturbance will approach from the north. The dry atmosphere across the area will moisten up. Patchy cloud cover will be on the increase this afternoon. Scattered showers and thunderstorms are expected this afternoon and tonight, however impacts on individual TAFs sites are uncertain. From 22Z/Fri-02Z/Sat is when convection should be at its greatest coverage so have focus thunderstorms in this window with a TEMPO group and showers prevailing in TAFs. Trends will be monitored and TAFs amended as necessary. Ceilings will lower with MVFR and possibly IFR overnight. A light north-northeast flow will develop at less than 10 knots. Outlook...
