AREA FORECAST DISCUSSION National Weather Service Albany NY 117 PM EDT Mon Aug 3 2020
SYNOPSIS. Following a dry afternoon, scattered showers and a few thunderstorms in advance of Tropical Cyclone Isaias will move across the region tonight. A steady light to moderate rainfall is expected for much of Tuesday as Isaias tracks toward our area. Isaias will then move across the region later Tuesday afternoon through Tuesday evening and bring moderate to heavy rainfall and gusty winds. High pressure builds in on Wednesday with drier weather.
NEAR TERM /THROUGH TONIGHT/. With showers ending across the Adirondacks, a brief period of dry weather will continue into this evening. While it remains partly to mostly cloudy, clouds should decrease in coverage for a short time later this afternoon. This will allow high temperatures to reach the mid-70s to mid-80s.
Meanwhile, TC Isaias will continue to track northward up the East Coast, being steered by a Bermuda high across the western Atlantic and a deep upper-level trough across the central US. Moisture has begun to advect northward in advance of Isaias across the mid- Atlantic states.
Clouds will increase again later this evening as the pre-storm showers approach. The first wave of showers look to begin between 10pm-midnight across the mid-Hudson Valley and Litchfield County, CT and reach the Adirondacks, Upper Hudson Valley and southern Vermont between 2-4 am. It is within this first round of showers that a rumble of thunder cannot be ruled out. Following this area of showers, a zone of stratiform light rain will begin to develop. Expected placement of this rain is across much of eastern New York into far southwestern Vermont. More showery activity is likely across southeastern Vermont, the Berkshires and Litchfield County. Lows tonight will bottom out in the 60s (with some upper 50s across parts of the Adirondacks).
SHORT TERM /TUESDAY THROUGH WEDNESDAY/. Focus in the short term is on impacts from TC Isaias. The system will be accelerating northward as it becomes squeezed between an upstream full-latitude trough and a downstream Bermuda high. The TC is forecast by the NHC to make landfall around 06Z Tuesday near the NC/SC border, then remain inland, reaching near NYC by 00Z Wed and over western ME by 12Z Wed. There continue to be timing differences among the models, although notably the 00Z ECMWF has trended toward the faster GFS, and now appears to be rather well in line with the NHC official forecast. A slight westward trend was noted in the 00Z deterministic guidance as well.
Deep layer moisture will continue to gradually increase Monday night into Tuesday morning ahead of the storm, with PWATs forecast to reach 1.50-1.75 inches. The pattern during this time period has been somewhat reminiscent of a southwesterly jet Predecessor Rainfall Event (PRE) per CSTAR research, where tropical moisture is advected poleward of the TC and interacts with ascent in the right entrance region of the upper level jet. However, it appears to be lacking a well-defined low level boundary. So generally showers and isolated thunderstorms will increase in coverage through the night Monday night into Tuesday morning, but likely without much of a flood threat yet. Highs Tuesday may finally fail to reach 80 degrees over most of the area with clouds and showers around.
It appears that the greatest heavy rainfall potential will occur over a 6-9 hour period associated with the approaching TC sometime between 18Z Tuesday and 06Z Wednesday, depending on the timing which is still uncertain. Models are depicting the heaviest swath of rain just west of the low track, associated with strong frontogenesis interacting with the juicy airmass (PWATs increasing to 2-2.25 inches, or +2 to +3 standard deviations). The system may be undergoing extratropical transition by this time. It is during this period that 3-hourly rainfall rates of 2-4 inches within this swath are possible as indicated by the NAM12 and HREF. Despite the antecedent dry conditions, these rainfall rates could produce flash flooding, so we will issue a Flash Flood Watch for the entire CWA except Herkimer County. The flash flood threat may be confined to a rather small geographic area just to the left of the storm track, but have opted to include most of the CWA due to uncertainty with the storm track.
Winds will be a secondary factor for most of the CWA, but may become strong with gusts possibly exceeding 40 mph especially if the storm tracks far enough west such that the southeastern quadrant of the storm passes through the CWA. This would be most likely in Litchfield/Dutchess/Berkshire Counties. The rainfall threat would be reduced in the southeast quadrant of the storm. There is a non-zero tornado threat in this quadrant as well, which is outlined by the marginal risk in SPC's SWODY2.
Much drier air takes hold in the wake of this system for late Tuesday night into Wednesday, with PWATs plummeting to less than an inch. Large contrast in forecast high temps ranging from the upper 60s in the southern Adirondacks to the mid-80s in the Mid Hudson Valley.
LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. The extended forecast period will feature a trend for fair and dry weather in the wake of Tropical Cyclone Isaias. Temperatures will be seasonable and then trend to slightly above normal readings into next weekend.
Wed Night into Thu . The upper level trough axis lingers upstream over southeast Ontario and the western Great Lakes region, but high pressure will be ridging in at the sfc from the central and eastern Great Lakes Region. The sfc high will move over the region Thursday. Decent radiational cooling will allow lows to drop off into the 50s with some upper 40 over the mtns. The subsidence from the high will yield mostly sunny conditions on THU with seasonable temps for AUG with upper 60s to mid 70s over the mtns, and upper 70s to lower 80s over the valleys.
Thu Night-Fri Night . High pressure will still be near NY and New England. Some short-wave energy associated with the mid and upper level trough axis approaching from the west may focus a few diurnally showers south and west of the Capital Region Friday pm into Friday night. Another comfortable couple of nights humidity level wise are expected with lows in the 50s to around 60F. Highs will be in the 70s to lower 80s.
Saturday-Sunday . Mid and upper level ridging starts to build in over the East Coast with high pressure in control at the surface. A weak mid and upper level disturbance moves through Saturday with a low grade isolated threat for a showers. Overall, rising heights aloft and H850 temps in the +15C to +17C range will allow temps to rise back above normal into the mid and upper 80s in the valleys and 70s to lower 80s over the higher terrain by Sunday. Humidity levels start to increase by the 2nd half of the weekend, as sfc dewpts get into the lower to mid 60s especially in the valleys.
AVIATION /17Z MONDAY THROUGH FRIDAY/. VFR stratus is approaching KGFL/KALB, with cigs around 4kft. These clouds should scatter out with time as we head into the late morning. Otherwise, some mid and high clouds will be around through the day. These clouds will begin to thicken and lower around sunset, and eventually some showers will become possible, especially after 06Z. Will continue prevailing VFR mention, although vsby could briefly drop to MVFR in a steadier shower after 06Z.
Winds will be elevated early this morning with southwest to west gusts up to 20 kt. The winds should diminish a bit in the afternoon from the west at around 10 kt. Winds will become light and variable overnight.
Outlook .
Tuesday Night: High Operational Impact Windy With Gusts To 30 kts. Definite SHRA. RA . TSRA. Wednesday: Moderate Operational Impact. Slight Chance of SHRA. Wednesday Night: No Operational Impact. NO SIG WX. Thursday: No Operational Impact. NO SIG WX. Thursday Night: No Operational Impact. NO SIG WX. Friday: No Operational Impact. NO SIG WX. Friday Night: Low Operational Impact. NO SIG WX. Saturday: Low Operational Impact. Slight Chance of SHRA.
FIRE WEATHER. Warm today with RH values falling to 45 to 60 percent and moderate westerly winds. TC Isaias will then approach, bringing increased humidity and periods of rainfall Monday night into Wednesday morning. The rain will be heavy at times, especially late Tuesday into Tuesday night.
HYDROLOGY. After a mainly dry day today, periods of rain associated with the northward progression of TC Isaias are expected Monday night into Wednesday morning. The heaviest rainfall looks to occur late Tuesday afternoon into early Tuesday night as the storm makes its closest approach. QPF of 2-4" is expected, with locally higher amounts up to 6" possible in a narrow swath left of the TC's track. Here, rainfall rates could exceed an inch per hour, and there could be 2-4" in a 3- hour period between 18Z Tuesday and 06Z Wednesday. There is still uncertainty on where the heaviest swath of rain will be, so a Flash Flood Watch has been issued for the entire HSA except for Herkimer county.
The ALY Hydro Service area continues to be in Abnormally Dry to Moderate Drought conditions /D0 to D1/ based on the latest US Drought Monitor. The latest MMEFS guidance continues to show low probabilities for river flooding.
Drier weather will return into the mid week period.
