AREA FORECAST DISCUSSION National Weather Service Albany NY 328 PM EDT Sat Jul 11 2020

SYNOPSIS. Scattered showers and thunderstorms continue into the overnight period as an upper level disturbance tracks through the area. Sunday may provide a brief reprieve from shower activity as weak ridging builds in at the surface. However, warm and muggy conditions continue into the new work week with chances for showers and thunderstorms most afternoons.

NEAR TERM /THROUGH SUNDAY NIGHT/. Scattered showers and thunderstorms will continue to impact the region through the remainder of the evening as an upper level shortwave gradually tracks eastward across NY. Much of the activity is currently concentrated in western/central NY and NE PA but is expected to track east over the next several hours. Some of these storms will be capable of becoming strong to severe with heavy rain and gusty winds the main threats. Temperatures are topping out near 90 in most places, depending on shower activity and cloud cover. However, with dew points in the upper 60s and low 70s, heat indices are in the mid 80s to mid 90s. So please continue to follow safety guidelines for both heat and severe weather today.

Tonight, showers and perhaps an isolated thunderstorm will be possible mainly across the southern Dacks as the upper shortwave tracks overhead. Overnight lows will be in the mid to upper 60s. Patchy fog is also possible as moisture gets trapped near the surface.

Sunday will be another warm and muggy day, but dry for most, as a weak surface ridge builds in at the surface. A few showers may be possible across the southern Dacks through the afternoon. Afternoon highs should range from the upper 70s in the Dacks to the upper 80s across the valley locations with partly sunny skies.

Sunday night will be dry and a bit cooler under weak westerly flow. Lows are expected to dip into the low to mid 60s and perhaps the upper 50s in the Dacks.

SHORT TERM /MONDAY THROUGH TUESDAY/. Monday and Tuesday will feature chances for showers and thunderstorms as an upper level trough and surface cold front swing across the region. For Monday, it appears that the best overlap of instability and deep layer shear may occur for areas south of I-90, where some stronger thunderstorms will be possible late morning through mid afternoon. Highs will be closer to normal, in the mid 70s to low 80s. Lows Monday night should cool off into the upper 50s to low 60s.

Sunday, coverage of showers and storms look more scattered as the upper trough and strong upper jet track through. Highs on Tuesday will be similar to Monday.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. The long term period begins with an area of high pressure building down from Canada through Wednesday. This will bring a brief period of dry weather and lower humidity. This high will then move to the east and as a result, a southwesterly return flow will advect more humid weather beginning Thursday and continuing into the weekend.

There remain model differences regarding when unsettled weather returns. Both models show an upper-level low across south-central Canada as an upper-level shortwave rotates around the base of the low and moves eastward toward the region. The faster solutions bring the chance for showers/t-storms as early as Thursday but others delay until Friday/Saturday. For now, will maintain a blended approach, which includes slight chance to chance pops all three days.

Temperatures will generally be in the 80s for the long term period (with some mid- to upper 70s in the higher terrain) with lows in the 50s/60s.

AVIATION /19Z SATURDAY THROUGH THURSDAY/. The main forecast concern for the terminals is the timing of showers and thunderstorms this afternoon and evening. VFR-MVFR conditions (cigs/vsbys) are expected to dominate much of the TAF period. As of 1pm EDT, showers and thunderstorms per WSR-88D doppler radar have begun to pop up over our FA as convective temperatures are starting to become realized. Greater, more widespread coverage of showers and thunderstorms are to our west in association with a shortwave that's tracking towards our area. Shower and thunderstorm probability and coverage will continue to increase over the next several hours as this shortwave moves closer to our FA. Should any storms move over the terminals, they will have the potential to bring cigs/vsbys down to MVFR levels. Otherwise expect VFR conditions. Thunder activity will decrease from south to north between 00z-04z. We could have some rain showers on the backside of the aforementioned shortwave impact KALB and KGFL after 04z or between the hours of 05z-09z. Have included Prob30 groups for light rain showers for both KALB and KGFL during this timeframe.

Late tonight around 05z or 06z, there is the potential for low stratus clouds in the MVFR range (possibly reaching IFR territory) to develop across the FA including some of the terminals (particularly KALB and KPSF). This could persist to about 11z-14z before things improve back to VFR conditions.

Winds will be south-southwest across KGFL, KPOU, and KPSF through the TAF period, and southeast trending southwest over KALB through the TAF period. Winds will be 10-15 kts gusting at times to 25 kts across KALB, KPSF, and KGFL over the next 2-3 hours or through about 20z/21z. Winds will then subside slightly to 5-10 kts through the remainder of the period. For KPOU, wind speeds be 5-10 kts through the TAF period.

Outlook .

Sunday Night: Low Operational Impact. Isolated SHRA. Monday: Moderate Operational Impact Numerous SHRA. TSRA. Monday Night: Moderate Operational Impact Scattered SHRA. TSRA. Tuesday: Low Operational Impact. Isolated SHRA. Tuesday Night: Low Operational Impact. NO SIG WX. Wednesday: Low Operational Impact. NO SIG WX.

FIRE WEATHER. Scattered showers and thunderstorms continue into the overnight period as an upper level disturbance tracks through the area. Sunday may provide a brief reprieve from shower activity as weak ridging builds in at the surface. However, warm and muggy conditions continue into the new work week with chances for showers and thunderstorms most afternoons.

HYDROLOGY. Rainfall from Fay was generally lighter than expected, with amounts remaining under one half inch in many areas, although localized amounts of 1-2 inches fell in the eastern Catskills, and one half inch to up to an inch in portions of the western/central Mohawk Valley. River responses have been minimal due to such dry antecedent conditions, although some in the eastern Catskills could still rise 1-2 feet.

Showers and thunderstorms with locally heavy rainfall will continue through this afternoon and evening. Isolated flash flooding can not be ruled out where persistent downpours occur, particularly in any urban/poor drainage areas.

Only isolated showers and storms are expected on Sunday, but a stronger system may bring more widespread showers and storms on Monday, again with locally heavy rainfall.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
