What forecasters said that day
The local office's own words before this flood watch 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 flood watch went out at Aug 21, 2:00 AM EDT, 2 hours 18 minutes earlier.
Area forecast discussion, Aug 21, 2:00 AM EDT, 2 hours 18 minutes before
AREA FORECAST DISCUSSION National Weather Service Albany NY 200 AM EDT Sat Aug 21 2021 .SYNOPSIS... Humid conditions will persist today with temperatures turning warmer than previous days due to breaks of sunshine. A few showers and afternoon thunderstorms may form with any storm capable of heavy downpours. Confidence is growing that Tropical Storm Henri will impact the region tomorrow into Monday with heavy rain and gusty winds the primary concerns, especially for western New England and areas east of the Hudson River. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... A muggy night remains in place with dew points through the region still in the mid 60s to low 70s. With our upper level disturbance still in place over the mid-Atlantic, southeasterly flow coming in off the Atlantic has persisted in the lower and mid - Hudson Valley. Then, areas north of I-90 are feeling the effects of the closed high in place over southern Canada with east to northeasterly flow in place. These two different wind regimes has focused moisture along I-90, especially in the eastern Catskill, where showers are developing and becoming enhanced as the easterly winds flow up the topography. NYS mesonet observations suggest showers in Schoharie, Greene and parts of Ulster County have already produced 0.25 - 0.50 inch of rain over the last 3 - 6 hours so these showers are producing decent rainfall. High res guidance shows the region of convergence in the eastern Catskills will lift northwestward through sunrise so we reduced POPs of chance to slight chance through 12 UTC. However, we expanded the slight chance POPs into the Mohawk Valley and southern Adirondacks in line with where the convergence zone tracks. Otherwise, the forecast is on track with temperatures changing very little overnight and staying in the upper 60s to low 70s due to humid conditions and ongoing cloud coverage. Fog has held off as well due to the cloud coverage. && .SHORT TERM /6 AM THIS MORNING THROUGH SUNDAY NIGHT/... Closed upper level low will remain situated over the mid Atlantic states for Saturday into Saturday night. Meanwhile, sharp upper level ridging will be stretching from the western Atlantic towards eastern and northern New England. With our area between these two features, we may see a few afternoon showers or t-storms that develop on Saturday. Otherwise, it looks partly to mostly cloudy and continued fairly muggy. With the humid conditions in place, any shower could have a brief heavy downpour, but coverage looks fairly low. There should be more breaks of sun on Saturday compared to Friday, so afternoon temps should reach the mid 80s for most valley areas (upper 70s to low 80s in the high terrain). Dewpoints will remain very high near 70. Although most of the diurnal convection should dissipate, can't still rule out a lingering shower or t-storm in Saturday night. Otherwise, it will be partly to mostly cloudy with lows near 70. The attention for Sunday into Sunday night will be for Tropical Storm Henri, which is expected to reach Hurricane status while moving northward offshore the mid Atlantic states. It will be lifting northward towards eastern Long Island and southern New England for during the day on Sunday, before weakening and lifting close to area for Sunday night. Recent model guidance from during the day today has shifted westward with the track and there is good consensus among both the operational model guidance and the hurricane models for a landfall across Long Island/southern New England. The storm looks to get captured westward thanks to the large upper level low over the mid Atlantic, as the ridge offshore will prevent this storms from hooking out to sea like they typically do. As a result, we are now expecting a period of heavy rainfall for during the day Sunday into Sunday night, especially for areas east of the Hudson Valley. At this point, heavy rainfall looks to be the main impact. The current forecast for wind gusts stays generally below tropical storm force in our area, with gusts up to 30 mph (mainly for the higher terrain), although this could be subject to change based on any changes in the storm intensity and track forecast. However, rainfall amounts could be at least several inches, with perhaps greater than 5 inches locally possible for parts of western New England. This could cause some issues with both flash flooding and river flooding for some eastern parts of the area. With dewpoints remaining near 70, high temps should be in the upper 70s with lows near 70 for Sunday night. && .LONG TERM /MONDAY THROUGH FRIDAY/... Guidance and the latest forecast from the National Hurricane Center suggest that Henri may be positioned close enough to the area on Monday for continued impacts, mostly rainfall. The actual track of Henri remains quite uncertain and that will determine what intensity of rain is expected. The latest guidance is trending farther west in the track, which could further lengthen our impacts and increase potential for moderate to heavy rainfall for at least parts of the area. But additional shifts west or maybe even east remain possible in the coming days. Will continue to monitor trends of Henri over the coming days. Otherwise, it will be a rather cloudy and humid day with highs in the 70s to lower 80s. Henri should begin to depart Monday night into Tuesday with a gradual drying trend as upper-level ridging builds overhead. Lows Monday night will be mainly in the 60s with highs Tuesday rebounding into the upper 70s to upper 80s. Slight upper-level height falls are expected on Wednesday, but the lack of any upper-level forcing should lead to another mainly dry day with only an isolated shower or thunderstorm possible due to the continued warm and humid air mass. Highs on Wednesday once again in the upper 70s to upper 80s. Next upper-level trough and surface front approaches Thursday into Friday with the return of more widespread showers and thunderstorms. Guidance differs on the timing of the front, however, with the GFS faster than the ECMWF. For now will place chance pops for both Thursday and Friday. Still warm Thursday with highs in the upper 70s to upper 80s but slightly cooler Friday with highs in the 70s to lower 80s. && .AVIATION /06Z SATURDAY THROUGH WEDNESDAY/... Main weather concerns for the ALY terminals and aviation operations over the next 6-9 hours will be VCSH trends and low stratus/fog/most potential. As of 1:30 AM EDT, doppler radar indicated light to moderate showers over the forecast area with most of the activity concentrated over Schoharie and points westward. VCSH over the TAF sites should gradually wane over the next few hours. Despite the broken to overcast cloud deck, ample low level moisture and light to calm winds could help promote low stratus, fog, or mist development overnight. KPOU as of this update is already experiencing low stratus, while PSF is experiencing some mist. Have included TEMPOs for the TAF sites through 12z. By 13z or so, any mist, fog, or low stratus should scour out giving way to a return to VFR conditions. By the early afternoon hours on Saturday, another round of light rain. Have included Prob30s for this possibility. Winds are expected to remain light and variable through the TAF period. Outlook... Saturday Night: Moderate Operational Impact. Chance of SHRA...TSRA. Sunday: Moderate Operational Impact. Likely SHRA. Sunday Night: High Operational Impact. Likely SHRA. Monday: Moderate Operational Impact. Likely RA. Monday Night: Moderate Operational Impact. Scattered SHRA. Tuesday: Low Operational Impact. Isolated SHRA...TSRA. Tuesday Night: No Operational Impact. NO SIG WX. Wednesday: Low Operational Impact. Isolated SHRA...TSRA. && .FIRE WEATHER... Humid and mainly cloudy conditions are expected overnight with RH near 100 percent and some patchy fog. RH values will only lower to around 70 percent on Saturday with a few spotty showers and thunderstorms. Light and variable winds are expected tonight, with southeast winds of 5 mph or less for Saturday. Humid conditions will continue for Sunday into Monday with the approach of Tropical Storm Henri. Heavy rainfall may impact parts of eastern New York and western New England with several inches of rainfall for some areas. && .HYDROLOGY... Flooding is still ongoing across the reservoirs of the upper Mohawk River, including Delta Lake and Hinckley, thanks to the recent heavy rainfall due to the remnants of what was once TC Fred. While these levels should be slowly falling, they will continue to remain flood stage through at least midday tomorrow. Otherwise, a few passing showers and t-storms are expected for tonight into Saturday. While a localized downpour can't be ruled out thanks to the very humid air mass in place, coverage of precip will be fairly scattered and basin average precip amounts should be low. For Sunday into Monday, Tropical Storm Henri will be moving towards southern New England and lifting north-northwest while weakening. Periods of heavy rainfall are now expected to impact the ALY HSA, especially for areas east of the Hudson Valley. The heaviest rainfall looks to occur from Sunday afternoon into Sunday night. Rainfall rates may exceed one inch per hour at times and total precip amounts will be 1 to 3 inches across eastern New York and 2 to 5 inches across western New England. Some locally higher totals can't be ruled out, especially across the Berkshires. There is a moderate threat for flash flooding across far eastern parts of the area and river flooding may be a concern as well, especially for the Housatonic River. As the storm's track comes into better focus over the next day or so, the extent/impacts of heavy rain will also become more clear as well.
