AREA FORECAST DISCUSSION National Weather Service Albany NY 148 PM EDT Mon Aug 10 2020

SYNOPSIS. Oppressive heat and humidity will be in place through the middle of the week, with the most widespread conditions on Tuesday. Mainly isolated or widely scattered showers and thunderstorms are expected until Wednesday, when a cold front moving through should provide greater coverage. Slightly cooler temperatures will occur towards the end of the work week.

NEAR TERM /THROUGH TONIGHT/. Heat Advisory in effect for much of the Hudson Valley, southern Taconics and Litchfield CT starting at Noon today .

As of 125 pm, water vapor showing anticyclonic flow pattern over the Northeast, suggestive of no synoptic scale forcing for ascent. Destabilization has occurred due to strong heating and an increase in low-level moisture, with dewpoints increasing to around 70F. SPC mesoanalysis suggests 2000-2500 J/kg of SBCAPE in place locally. Satellite shows some agitated cu over the southern Adirondacks toward the Glens Falls area, as well as around the Capital District and Helderbergs. More stable air with a lack of cu noted over the Mohawk Valley where it rained earlier. Going forward, expect isolated to widely scattered showers/storms to develop especially within and downstream of the agitated cu field. Due to weak deep-layer shear of only 10-20 kt and the absence of large-scale forcing, do not expect organized convection, but some gusty winds and heavy downpours are possible with the respectable instability in place. Any convection should quickly diminish after sunset. Heat indices expected to be near 95F within the Hudson Valley and northwest Connecticut where Heat Advisories continue.

Mild night expected tonight with a light southerly gradient and muggy conditions. Lows in the mid-60s to low 70s.

SHORT TERM /TUESDAY THROUGH WEDNESDAY/. Heat Advisory in effect through 8 PM Tuesday for much of the Hudson Valley, southern Taconics and Litchfield CT .

Heat Advisory will likely need to be expanded to include more valley areas such as the Mohawk Valley, upper Hudson Valley and the CT River Valley of southeast VT. Dewpoints expected to remain around 70, with the peak of the warmest 850 mb temperature anomalies occurring of +1 to +3 STDEV (from 00Z GEFS). Widespread temps in the lower 90s combined with the high dewpoints will yield dangerous heat index values in the mid to upper 90s for most valley locations. Convective potential appears to be slightly greater on Tuesday, as guidance is showing some gradual height falls aloft along with a surface cold front approaching from the Great Lakes. Forecast SBCAPE looks similar to Monday (1000-2000 J/Kg), along with weak deep layer shear < 20 kt again. However, with more in the way of forcing we are expecting scattered coverage during the afternoon north and west of the Capital District, spreading eastward to around Albany during the early evening. Again, any storm could produce local downpours and brief gusty winds. Due to weak shear, organized/severe convection is not anticipated.

As the cold front slowly moves eastward across the region, will need to mention slight to low chance of showers/storms Tuesday night. There will still be some instability in the warm/humid air mass although will only mention isolated thunder. A few downpours may occur in this environment with PWAT anomalies of +1 to +2 STDEV.

Wednesday looks to when there should be the best potential for greater coverage of convection, as the cold front continues to slowly move across the area. The front will interact with a continued warm/humid air mass, with scattered showers and thunderstorms across much of the area expected. Far northern areas in the Adirondacks may see drying behind the front during the afternoon, but it will remain unsettled across the rest of the area. Deep layer wind shear still forecast to be weak, so again not expecting any organized/severe convection. A few rogue strong wind gusts cannot be ruled out in some of the taller storms. While temps will be slightly cooler compared to Tuesday (85-90F for highs), additional Heat Advisory may be needed across parts of the area ahead of the cold front, such as in the mid Hudson Valley, southern Taconics and Litchfield CT. At this time, we are forecast heat index values in the lower to mid 90s in these areas.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. The extended forecast begins with a cold front settling south of the region Wednesday Night into Thursday. High pressure will be building in from Quebec. The question will be how far south the boundary sets up before becoming stationary for chances of showers/isolated thunderstorms late in the week into the weekend, especially south of the Capital Region.

Wednesday night into Thursday . The cold front passes through the forecast area and moves south of southern New England and northern NJ back into south-central PA. The best chance of showers and isolated thunderstorms Wed night will be from the Capital Region south and east. PWATS will be in the 1.50-2.00" range according to the 00Z GFS south and east of Albany, so some locally heavy downpours will be possible Wed night. Lows will be in the mid 50s to lower 60s north and west of the Capital District and the Saratoga Region, and mid 60s to around 70F south from those areas south and east. A Canadian sfc anticyclone will attempt to build in from James Bay on THU, but with the front only making slow progress southward, a threat for a chance of showers and isolated thunderstorms will continue on THU from the I-90 corridor south and east. Max temps will still run above normal with upper 70s to lower 80s over the higher terrain, and mid and upper 80s in the lower elevations.

Thursday Night into Friday . A low confidence forecast continues based on the placement of the front south of the region. However, we are going to trend the forecast closer to the latest 00Z ECMWF with the front being farther south closer to the Mid Atlantic States, as the 00Z GFS is slightly further north. Basically, a slight to low chance of showers will be possible closer the I-84 corridor and locations south of the Capital District. There could also be isolated thunderstorms. Further north, we kept it dry or just placed an isolated threat of a shower or thunderstorm. Again, if the front is closer to the 00Z ECMWF, a drier day will prevail. After lows in the upper 50s to mid 60s, then high temps will be in the upper 70s to mid 80s across most of the forecast area. Humidity levels will gradually lower with sfc dewpts in the mid 50s to lower 60s north of the Capital Region and mainly mid and upper 60s south and east.

Fri Night into Sunday . High pressure begins to build in from eastern Quebec, New Brunswick and northern ME. The northeast flow with the anticyclone building in may yield a few showers south and west of the Capital Region to open the weekend, but we tried to trend towards a drier weekend which is more reflective of the 00Z ECMWF. The ECMWF would have an H500 mid and upper level ridge set right up over NY and New England. Temps continue to gradually cool with mid 70s to lower 80s for highs on Saturday. A wave of low pressure passing along the front over the mid Atlantic States, and a warm front moving slowly towards the region late Sunday may bring a slight to low chance of showers and isolated thunderstorms especially west of the Hudson River Valley late in the day. Max temps will be similar to Saturday, and lows both days will be mainly in the upper 50s to mid 60s with humidity levels being slightly more comfortable.

AVIATION /18Z MONDAY THROUGH SATURDAY/. Through 18z/Tue . VFR conditions will continue for much of this afternoon with a mix of few-sct fair weather cu and mid-level clouds. A few isolated showers/t-storms have begun to develop, mostly along a pronounced arcing cu field moving eastward across New York State. The best timing chances for showers will be along this cu field, so for KALB/KGFL between 18z- 20z, then between 19z- 00z at KPSF/KPOU. In any heavier shower or t-storm, cigs/vsbys can lower into the IFR/MVFR range, as indicated in the TEMPOs.

Showers and clouds will clear out this evening leading to a mainly clear night. Some patchy low clouds and/or IFR fog/mist will be possible later tonight at all locations except KALB, pending on whether showers occurred at the sites or not. Any low clouds or fog/mist will dissipate Tuesday morning and give way to a mostly sunny start with just a few passing high clouds.

Wind will be mainly out of the southwest at 5-10 kt through this afternoon, then become light and variable tonight. Wind will then be out of the south to southwest at 6-12 kt tomorrow morning.

Outlook .

Monday Night: No Operational Impact. NO SIG WX. Tuesday: Moderate Operational Impact Chance of SHRA. TSRA. Tuesday Night: Moderate Operational Impact Chance of SHRA. TSRA. Wednesday: Moderate Operational Impact Chance of SHRA. TSRA. Wednesday Night: Moderate Operational Impact Chance of SHRA. TSRA. Thursday: Low Operational Impact Slight Chance of SHRA. TSRA. Thursday Night: Low Operational Impact. NO SIG WX. Friday: Low Operational Impact Slight Chance of SHRA. TSRA.

FIRE WEATHER. Oppressive heat and humidity will be in place through the middle of the week, with the most widespread conditions on Tuesday. Mainly isolated or widely scattered showers and thunderstorms are expected until Wednesday, when a cold front moving through should provide greater coverage. Slightly cooler temperatures will occur towards the end of the work week.

Relative humidity values will drop to minimum values of around 50 to 65 percent this afternoon, increasing to maximum values of between 85 and 100 percent tonight. RH values will drop to around 45 to 55 percent Tuesday afternoon.

Winds today will be west to southwest around 10 mph or less, becoming south to southwest around 5 mph tonight. Winds on Tuesday will be southerly around 5 to 10 mph.

HYDROLOGY. No widespread hydrological problems expected in the ALY Hydro Service Area over the next several days.

Forecast rainfall will be mainly from isolated to scattered showers and thunderstorms, and will vary greatly from location to location. Localized heavier rainfall is possible where thunderstorms occur.

The most widespread threat of showers and thunderstorms looks to be late Tuesday into Wednesday with a slow moving cold front. Localized ponding of water or poor drainage flooding of low lying areas is possible where thunderstorms produce locally heavy downpours. No river flooding is forecast at this time.

Mainly drier weather is expected to return later in the week, although southern areas could still see some showers lingering.
