DBTWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Albany, NY wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 5, 1:29 PM EDT, 1 hour 49 minutes earlier.
Area forecast discussion, Jun 5, 1:29 PM EDT, 1 hour 49 minutes before
AREA FORECAST DISCUSSION National Weather Service Albany NY 129 PM EDT Fri Jun 5 2020 .SYNOPSIS... Warm and humid with isolated to scattered showers and thunderstorms this afternoon and evening. A cold front approaching from the Great Lakes will bring additional scattered showers and thunderstorms late tonight into Saturday morning. High pressure will then bring cooler and much less humid conditions for Sunday through early next week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... As of 115 PM, Warm and humid today with dew points mainly in the 60s across the area. Isolated convection has begun to initiate mainly in the vicinity and north of I-90 where there has been more sunshine. No lightning has been detected yet. Have instability and shear has increased with the SPC mesoanalysis indicating 0-6km effective bulk shear of 40 knots when storms are firing and lower values to the south. PWATs range from 1 to 1.5 inches with the higher values south and east of Capital District so heavy downpours expected. Any stronger thunderstorms are expected to remain to our south. We are outlooked for general thunderstorms by the Storm Prediction Center. && .SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/... Tonight, other than isolated evening showers/thunderstorms mainly across the mid Hudson Valley and NW CT, a general lull in convection is expected due to limited forcing. However, after midnight and especially closer to daybreak, a cold front and upper level height falls will approach from the west. Will have to watch for any upstream convection across the Great Lakes/southern Ontario which occurs this evening, which could potentially reach into at least the southern Adirondacks and Mohawk Valley region after midnight. 0-6 km shear increases during this time period ahead of the approaching mid/upper level trough to 40-50 KT across northwest areas, so should any deeper convection occur, will have to watch for strong wind potential. For now, SPC has region within general thunderstorm category with expectation for diurnal minimum in instability to limit convective potential. Otherwise, warm and muggy overnight, with lows mainly in the 60s, although some portions of the Hudson River Valley could remain closer to, or slightly above 70. Saturday, aforementioned cold front should be across the SW Adirondacks/Mohawk Valley around or shortly after sunrise, and continuing to track E/SE. Some lingering showers/isolated thunderstorms may be ongoing with or ahead of the front. As the front continues tracking east/southeast into the mid Hudson Valley, Berkshires and southern VT during the mid to late morning hours, SB CAPES may rise to 1000 J/kg or greater, along with 0-6 km shear of at least 30-40 KT. Scattered thunderstorms should develop in these areas, and again, will have to watch for any strong wind potential with deeper convection. Behind the front, becoming mostly sunny and breezy (west/northwest winds possibly reaching 25-35 mph at times), with temps reaching the mid 70s to lower/mid 80s, along with lowering dewpoints. However, a secondary cold front and additional cooling aloft with the approach of the main trough could allow additional scattered showers/isolated thunderstorms across the southern Adirondacks, southern VT and upper Hudson Valley later in the afternoon through Saturday evening. Saturday night-Sunday night, main upper level trough/cold pool passes across the region Saturday night into Sunday morning. Enough low level instability could allow for isolated/scattered showers to persist across portions of the Mohawk Valley and southern Adirondacks during this time. Lows Saturday night in the 40s across northern areas, and 50s central and south. Some brief showers could occur Sunday morning across the Capital Region and mid Hudson Valley east into the Berkshires/NW CT and southern VT. Improving conditions for Sunday afternoon, with highs in the 60s for the mountains, and lower/mid 70s in valleys. Clear and chilly for Sunday night, with lows in the mid 40s to lower 50s, except for some 30s across portions of the SW Adirondacks. && .LONG TERM /MONDAY THROUGH THURSDAY/... Big bubble, no trouble through mid week as an anomalously strong upper ridge remains in control of our sensible weather. Seasonable temperatures on Monday will warm to the mid and upper 80s for Tuesday and Wednesday. Skies will be mostly sunny each day. Because we are near the longest days of the year, there will be limited time for temperatures to cool off each night, with lows in the 50s to low 60s each night. As we move into Thursday, the sensible weather becomes a bit more uncertain. Both global models track the remnants of Cristobal into Ontario (by Wednesday night) as it gets absorbed into the upper level trough. At the surface, a frontal boundary extends from Ontario, southward towards the Gulf coast. Additionally, ridging strengthens across the central CONUS. This ridge continues to strengthen and push northward into Canada, and should be the deciding factor as to how the upper trough over Canada evolves and moves east. Models do remain consistent bringing a series of frontal boundaries through our forecast area. The first of which will track through Thursday night into Friday with a decent slug of moisture connected to the Gulf. The second frontal boundary passage will likely pass through sometime Saturday morning with drier air filtering in behind it. This will result in scattered showers Thursday night through the day Saturday. Temperatures Thursday and Friday will be closer to normal with highs in the 70s to low 80s. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... Flying conditions have mainly be VFR early this afternoon, although some periods of lower stratus have been occasionally allowing for MVFR cigs at KPSF. Will generally anticipated VFR conditions through the rest of the day. There have been some scattered showers developing and it's possible that a stray brief shower or even a t-storm passes over a terminal through this evening. However coverage will be rather low and brief in duration so will only address with a VCSH for now. South to southwest winds will be 5 to 10 kts. Overnight, any showers or t-storms will dissipate allowing for VFR conditions with just some patchy lingering mid level clouds. It will remain rather muggy, so some MVFR/IFR fog and low stratus may develop by late in the night, mainly for KPSF/KGFL. After sunrise, any fog/low stratus looks to quickly dissipate. The front will pass through early in the day on Saturday. This will allow southerly winds to become westerly by the mid to late morning hours and increase to 10 to 15 kts. Some sct-bkn cigs at 5-8 kft will slowly lower in coverage through the day with VFR conditions. Outlook... Saturday Night: Low Operational Impact. Isolated SHRA...TSRA. Sunday: Low Operational Impact. NO SIG WX. Sunday Night: No Operational Impact. NO SIG WX. Monday: No Operational Impact. NO SIG WX. Monday Night: No Operational Impact. NO SIG WX. Tuesday: No Operational Impact. NO SIG WX. && .FIRE WEATHER... Warmer and more humid today with isolated to scattered showers and thunderstorms, especially south and east of Albany. A cold front will bring additional scattered showers/thunderstorms late tonight into Saturday morning, with breezy conditions developing in the wake of the front Saturday afternoon. High pressure will bring fair weather for Sunday afternoon through early next week. && .HYDROLOGY... Scattered showers and isolated thunderstorms are expected today through Saturday morning, as a warm front initially lifts northward, followed by a cold frontal passage Saturday morning. Although widespread heavy rain is not expected, locally heavy downpours within showers/thunderstorms could produce ponding of water on roadways and in low lying areas given PWAT's of around 1.5 inches. Mainly dry weather is then expected Sunday through early next week.
