DBTWhat forecasters said that day
The local office's own words before this tornado 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 tornado warning went out at Aug 27, 1:36 PM EDT, 29 minutes earlier.
Area forecast discussion, Aug 27, 1:36 PM EDT, 29 minutes before
AREA FORECAST DISCUSSION National Weather Service Albany NY 136 PM EDT Thu Aug 27 2020 .SYNOPSIS... A low pressure system and a slow moving moving frontal boundary will bring showers and thunderstorms today. Some of the thunderstorms will be strong to severe during the afternoon hours, with damaging winds and large hail, especially for areas south of the Capital Region. Although dry weather will briefly return for Friday, more showers and thunderstorms are expected on Saturday. Drier and comfortable weather will return for Sunday into Monday. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... As of 1050 AM EDT...A warm front still remains south of most of the forecast area late this morning, though some breaks in he clouds are noted in the lower to mid Hudson Valley with the sfc winds shifting to the southwest. A weak sfc wave is moving along the boundary with light northeast to southeast winds with periods of showers continuing over the northern most zones into the southern Adirondacks. A cluster of showers and thunderstorms moved into the eastern Catskills, but weakened per the stable environment indicated by the 12Z KALY sounding. An impressive low to mid level wind field exists aloft, as an H500 wind max of the 50-70 kts has moved into the region. Temps are generally in the lower/mid 50s to around 60F from the Capital Region north and east with lower 60s to lower 70s this hour based on the NYS Mesonet. We continue to monitor other showers and some thunderstorms drifting off Lake Ontario into the western Mohawk Valley. These continue to be elevated parcels with MUCAPE generally 500 J/kg or less per the SPC RAP Mesoanalysis. Some slight changes were done with the PoPs and weather. PWATS continue to rise into the 1.2-1.7" range. The higher values are generally south and west of the Capital Region. The warm frontal boundary looks to continue to slowly move northeast and eventually stall out near or over the Mohawk Valley/Capital District this afternoon /close to the I-90 corridor/. A strong mid-level jet will persist aloft and portions of central and eastern NY will get into the right entrance region of the anomalous jet in the 50-70 kt range. The latest 00Z HREFS continue to indicate 0-6 km bulk shear will be about 40 to 50+ kts, setting the stage for the potential for some supercells, which may gradually organize into a convective line per the latest CAMS. The big question remains where the cutoff will be between the stable and unstable air mass. It looks like the southern 6 counties have the greatest chance /Greene...Columbia...Berkshires...Dutchess...Ulster and Litchfield Counties/. However...slightly further north will be right on the fence into the Capital District and Mohawk Valley. These areas are in a Slight to Marginal Risk, while further south continues in an Enhanced Risk in the SPC Day 1. There will be sharp gradient of instability across the region today. Just south of the front, breaks in the clouds will allow for plenty of instability, with MLCAPE of 1000-1500+ J/kg is expected. Further north, much lower instability is likely and the severe potential decreases. Strong to potentially severe convection will be developing on the southern edge of the initial activity late this morning for the lunchtime to early afternoon hours. Based on hires model guidance (12Z 3km HRRR and NAMNest), they look to form across the Mohawk Valley, Schoharie County and into the Capital Region. The 12Z NAMnest is a little further north, but this is with elevated instability with some of the storms. These storms may initially form within the elevated instability but will become more surface- based parcels, as they move south and southeastward from the roughly the I-90 corridor. These storms will likely take on supercell characteristics for the afternoon hours as they move towards the eastern Catskills, mid Hudson Valley, Taconics and into The Berkshires and NW CT. Eventually, these cells will form a QLCS/squall line, as they drop south of the area for this evening. The main threat with the initial supercells will be both damaging winds and large hail /possibly up to 2" in diameter/. NAM BUFKIT soundings show steep lapse rates for KPOU this afternoon, both low and mid levels. Mid level lapse rates could be as high as 7 C/km, which would be favorable for large hail. Near/just south of the boundary, long curved hodographs favored the development of a tornado or two as well. 00z HREF shows 0-1 SRH in excess of 200 m2/s2 over a large part of the area with mean STP values of 1 to 2. As was the case with several of the last few tornadic days in this region (May 15, 2018 and May 22, 2014), a sharp warm front, interacting with the local terrain, can be the focus for tornadic development in this region, especially if the sfc to low-level winds back ahead of the boundary in the Hudson River Valley. Eventually, the threat will change to mainly damaging winds, as the storms become linear. The chance for precip will decrease from north to south through the afternoon hours, as the boundary and a weak sfc wave starts to shift southward towards the mid- Atlantic States. Temps this afternoon will vary, thanks to the boundary draped through the area. While some parts of the Adirondacks will only remain in the upper 50s for highs, the mid Hudson Valley should reach the mid 80s. Temps in the middle will be the most difficult to determine, but currently forecasting highs in the mid 60s to near 70F in the Capital Region. && .SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/... Showers and thunderstorms will continue to diminish from north to south this evening and the threat for severe storms will drop further south towards PA/NJ/NYC. Meanwhile, some clearing is expected overnight, as the frontal boundary shifts southward. Lows will range from the upper 50s in the north to the upper 60s in the south. On Friday, skies should start off fairly clear but clouds will gradually be increased once again through the day as the frontal boundary starts to shift back northward. It should be dry for most of the day, as some showers may start to spread back into western and southern area towards late in the day. Along with temps warming back through the 70s (and even some 80s for far southern areas), dewpoints will be rising back into the 60s as well. For Friday night, some rounds of showers and embedded thunderstorms are expected as the front lifts back north as a warm front. It won't be raining the entire night, but most areas should see something as the boundary lifts back northward. Lows will mainly be in the 60s and it will start to feel more and more muggy once again. Saturday has the potential to be another activity day. PWATs will rise towards 2.00 inches across the entire area, aided by the remains of TC Laura which will be passing across the mid Atlantic States. We will be in the warm sector, as the warm front will be north of the area, but a storm's cold front will be quickly approaching from the west. Some showers and thunderstorms are expected. Not anticipating too much severe storms due to limited instability thanks to abundant cloud cover around, but locally heavy downpours are certainly possible considering the high PWATs and good setup for heavy downpours in place. Will mention this threat in the HWO. Highs should be in the 70s for most. Will lower POPs on Sat night as cold front moves through the day, allowing cooler and less humid air to move back into the region. Lows generally in the 50s/60s for Sat night. && .LONG TERM /SUNDAY THROUGH THURSDAY/... Upper-level troughing will start the long term period on Sunday with the surface low associated with the Saturday system spinning across southern Quebec. As 850 hPa temperatures fall to between 5-10C, lake- enhanced clouds and showers will be possible across the Mohawk Valley and Adirondacks during the morning and afternoon. A few upslope showers will be possible across western New England as well. Otherwise, expect a partly to mostly sunny and less humid day with highs ranging from the lower 60s across the Adirondacks to the upper 70s in the mid-Hudson Valley. Lows Sunday night Will fall into the 40s to lower 50s under a mostly clear sky. Monday will be sunny and dry as high pressure and slight upper-level ridging builds across the region. It will remain a quite comfortable day with highs similar to Sunday (60s higher terrain to 70s valleys). Expect another cool night Monday night with lows once again in the 40s/50s. Longwave troughing starts to build back in during Tuesday and Wednesday as the surface high pushes off to the east. A disturbance will attempt to form across the Appalachians and track northeastward toward our area. Meanwhile, a secondary surface low and associated cold front across the central United States will advance eastward. Low-level flow will shift back to the south and west and advect slightly more humid weather into the region (dew points rising into the upper 50s to mid-60s by Wednesday). There are model differences regarding how these two features eventually evolve, but the chance for showers and possibly a few thunderstorms will return on these two days. Highs both Tuesday and Wednesday will be range from the upper 60s in the higher terrain to the 70s elsewhere with lows in the 50s to lower 60s. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... Main forecast concern for the 18z TAF period will be centered around the ongoing rain and convection over the forecast area. Stratiform rain continues to fall over KGFL with showers and embedded thunder over KALB/KPSF. For KPOU, cigs/vsbys will be in VFR at the onset of this TAF period, before severe thunderstorms approach the terminal after about 19z. Cigs are expected to remain in at least MVFR levels through much of the period (through 13-15z/Fri.) with rain and/or thunderstorms ending by 20z/Thurs for KGFL, 22- 23z/Thurs for KALB/KPSF, and about 03-04z/Fri for KPOU. Cigs are expected to return to VFR between 13z-16z/Fri across all the terminals. Winds for the most part will be light and variable through the TAF period. Outlook... Friday Night: High Operational Impact. Likely SHRA...TSRA. Saturday: High Operational Impact. Definite SHRA...TSRA. Saturday Night: Moderate Operational Impact. Chance of SHRA...TSRA. Sunday: No 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.

Showers and thunderstorms are expected through the day today, with the chance for some severe storms this afternoon into this evening, especially for southern areas. RH values will only be as low as 60 percent today. Although winds will be fairly light through the day, stronger winds are possible within thunderstorms. Some areas will see a wetting rainfall today, but not all areas will heavy thunderstorms. Mainly dry conditions are expected tomorrow. RH values will be as low as 50 to 60 percent with light westerly winds. A better chance for showers and thunderstorms is expected Friday night into Saturday for the entire area. && .HYDROLOGY... Frontal boundary will be slowing moving across the region today. Showers and thunderstorms may contain locally heavy downpours today and isolated flash flooding cannot be ruled out. Flooding of urban, poor drainage and low lying areas will also be possible. After a mainly dry day on Friday, more showers and thunderstorms are expected Friday night into Saturday. High PWAT values will allow for more heavy downpours and some flash flooding/urban flooding cannot be ruled out once again. Dry weather is then expected for Sunday into Monday.

The Storm Prediction Center has Schoharie, Albany, Rensselaer and Berkshire Counties south into the eastern Catskills, Mid Hudson Valley, southern and central Taconics and Litchfield County Connecticut in an enhanced risk for severe thunderstorms this afternoon into early this evening. The greatest risk for severe weather will be along and south of the Interstate 90 corridor into the mid Hudson Valley and northwest Connecticut with large hail, damaging winds and isolated tornadoes possible. The greatest threat for severe weather looks to be 1 pm to 8 pm. There continues to be some uncertainty how far north the severe threat will be from Albany northward due to a cooler and more stable air mass in place. Stay tuned for later forecast updates on the potential for severe weather. TAW
