AREA FORECAST DISCUSSION National Weather Service Albany NY 355 PM EDT Sat Mar 28 2020

SYNOPSIS. Periods of rain will occur tonight into Sunday. A rumble of thunder possible south of the Capital Region. Skies will remain mostly cloudy with scattered showers for early in the week. High temperatures will generally be near normal this weekend into early next week.

NEAR TERM /UNTIL 6 AM SUNDAY MORNING/. An area of rain over our region continues to build east and southeast with the back edge in western/central NY. A low level jet segment will be exiting into the evening, with decreasing low level forcing and decreasing isentropic lift. The steadier rain should exit through the evening but lingering areas of light rain and sprinkles will occur the rest of the night, while convection in the warm sector in the OH Valley through PA will stay south of our region. Boundary layer winds will become more south to southeast by daybreak, increasing the low level forcing and supporting an expansion of the rain around daybreak.

So, rain likely in most areas with the steadiest rain in the evening, and dry air at low levels associated with strengthening high pressure in SE Canada helping temperatures to fall toward wet bulb levels tonight. Lows in the upper 30s to lower 40s but a few mid 40s southern areas and mid 30s northern areas.

SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/. Stronger warm advection occurs Sunday but the strengthening high pressure in SE Canada will set up a boundary over eastern NY blocking the warm sector from getting any farther east than the western Mohawk Valley and maybe parts of the Schoharie Valley, if that. The best low level convergence and convective instability tracks south of our region and low level flow from the southeast dominates most of our region.

So, not including thunder anywhere but locally heavy rain due to enhanced isentropic lift and approaching upper dynamics could fall in areas along and west of the Hudson Valley and also in southern VT with some upslope also aiding in heavier rain in areas of terrain. Highs Sunday in the upper 40s to lower 50s but mid 40s northern areas and mid 50s western Mohawk Valley.

Boundary layer flow shifts to west and southwest Sunday evening, and boundary layer cold advection begins to spread into our region. Precipitation becomes more showery as upper dynamics from a closed upper low tracking through the Great Lakes approaches. The closed upper low is expected to drop slowly south and east through Monday and Tuesday through northern and eastern NY and eventually New England.

There could be some morning breaks in the clouds in some areas before instability supports development of widespread clouds and scattered showers. Low level flow turns more northwest as the high pressure in Canada retreats far north and weak low pressure northwest of our region builds east and south. Similar conditions are expected Tuesday but with cooler boundary layer temperatures more proximate to the center of the closed upper low. There should be some snow shower activity Monday night into parts of the southern Adirondacks and southern Green Mountains.

Highs Monday in the 50s but mid to upper 40s northern areas and upper 50s southern areas. Highs Tuesday in the mid to upper 40s but near 50 southern areas and lower 40s northern areas.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. Overall the longwave pattern across the CONUS is expected to be rather flat with uncertainties in the details. A short wave trough and its associated low will move off the Southeast Coast and head out to sea Wednesday. Otherwise weak ridging is expected at the surface across the region with a weak upper level low lingering overhead through mid week. A low pressure system should be in the approach by late in the week bringing chances for showers to the area with mainly rain showers expected with snow showers across the higher terrain at night.

Temperatures are expected to be near seasonable levels to slight above normal as we close out March and head into April.

AVIATION /20Z SATURDAY THROUGH THURSDAY/. A warm front approaching the region will bring a steady rain late this afternoon/evening through the end of the TAF period. For the remainder of the afternoon, however, expect some light rain as the atmosphere saturates. Flying conditions are expected to reduce to IFR by late this evening and remain there through the remainder of the period as the steadier rain arrives. Just beyond the TAF forecast period, there is a slight chance for thunderstorms.

Winds will generally be from the southeast to east through the period with speeds around 5 to 10 kts. Looking at model wind profiles, it is conceivable that LLWS will be required at the terminals in the pre-dawn hours Sunday. For now, have not included in the TAFs.

Outlook .

Sunday Night: High Operational Impact. Likely SHRA. Monday: High Operational Impact. Likely SHRA. Monday Night: Moderate Operational Impact. Chance of SHRA. Tuesday: Low Operational Impact. Slight Chance of SHRA. Tuesday Night: Low Operational Impact. Slight Chance of SHRA. Wednesday: Low Operational Impact. Slight Chance of SHRA. Wednesday Night: Low Operational Impact Slight Chance of SHRA. SHSN. Thursday: Moderate Operational Impact. Chance of SHRA.

FIRE WEATHER. Periods of rain will occur tonight into Sunday. A rumble of thunder possible south of the Capital Region. Skies will remain mostly cloudy with scattered showers for early in the week. High temperatures will generally be near normal this weekend into early next week.

Wet weather and light winds will keep RH values elevated through Monday.

HYDROLOGY. Rain will overspread the area from southwest to northeast through this evening. Periods of rain will persist through the remainder of the weekend, with isolated thunderstorms also possible on Sunday. The heaviest rainfall through tonight should be across Ulster/Dutchess/Litchfield Counties, where amounts in excess of an inch will be possible.

Total QPF over the weekend is expected to be around an inch across much of the area with higher amounts of 1 to 2 inches across the southern Adirondacks and higher terrain of the eastern Catskills and southern Green Mountains. NOHRSC estimates 1 to 3 inches SWE across the southern Adirondacks and southern Green Mountains with as high as 6 inches over the high terrain in Hamilton County. The combination of rain and snowmelt will lead to river rises, although there remains uncertainty with respect to the magnitude of both factors. The cool temperatures may limit snowmelt somewhat. At this time, the Sacandaga River at Hope is expected to reach flood stage Sunday evening with minor flooding forecast. MMEFS suggests the Schroon at Riverbank could reach minor flood stage Monday as well as the West Canada Creek at Hinckley Reservoir.

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.
