Area forecast discussion, Jul 23, 7:32 AM EDT, 2 hours 5 minutes before
Area Forecast Discussion National Weather Service Albany NY 732 AM EDT Mon Jul 23 2018 .SYNOPSIS... A tropical air mass will remain in place through at least Wednesday, as a frontal system remains west of the region, while high pressure remains anchored across the north Atlantic Ocean into New England. Weak disturbances tracking northward will bring some showers and thunderstorms through midweek, with the greater coverage expected today, and then again Wednesday. The frontal boundary should move east of the region Thursday, bringing some relief from the oppressive humidity levels. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... As of 615 AM EDT, main band of moderate to heavy rain remains across the southeast Catskills into the eastern Mohawk Valley and southwest Saratoga County, and continues to drift north/northwest. Additional downpours, a bit more scattered in coverage, continue across the Capital Region east into southern VT/western MA, and south through the mid Hudson Valley and NW CT. For today, the combination of persistent low level convergence, and upper level shortwave energy tracking northward across central PA/NY should allow for numerous showers and isolated thunderstorms to continue through much of the day. Areal coverage should become greatest near and just west of the Hudson River through the morning, as the low level convergence shifts westward. With PWAT's remaining near 2 inches, as well as wind direction from the south/southeast through a deep depth of the lower atmosphere, locally heavy rainfall with some training potential remains possible through today. Most models suggest 500-1000 J/kg of MUCAPE for this afternoon, although higher values of 1000-2000 J/kg are possible in any areas which receive breaks of sun, which may be across the western Mohawk Valley and southwest Adirondacks later this morning. Will keep mention of isolated thunderstorms through the day, with heavy rainfall being the main attribute accompanying any storms. Deep layer shear will remain 25-30 KT, so should any embedded deeper convection form, it could briefly organize enough for some isolated gusty winds. Temperatures should reach the upper 70s to lower 80s, although could be locally warmer if any prolonged breaks of sun develop. Dewpoints will remain in the lower 70s for most lower elevations, thus remaining quite muggy through the day. && .SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/... Tonight, the best low level forcing should continue shifting westward, and with the loss of diurnal heating and lack of significant forcing mechanism, expect showers/isolated thunderstorms to decrease in coverage shortly after sunset. Otherwise, warm and humid with lows in the mid 60s to lower 70s. For Tuesday, models suggest the best forcing and associated deep moisture plume should shift west into central/western NYS, as strong upper level ridging from the North Atlantic builds westward into New England. Will scale back Pops into the isolated Hudson River Valley, with scattered coverage to the west and east. Thunder potential looks very low, esp from the Hudson Valley east, as mid level warming occurs with the brief impingement of the upper level ridge. With some breaks of sun expected, afternoon higher temperatures should reach the mid/upper 80s in lower elevations, with mid 70s to lower 80s across higher terrain, and perhaps portions of the western Mohawk Valley where more clouds may remain prevalent. Tuesday night-Wednesday night, upper level height falls overspread the region from west to east, as the frontal system and associated deep tropical plume also move eastward. PWAT's surge to around or over 2 inches, combined with forcing with the approach of the remnant upper level trough. Showers and embedded thunderstorms should increase from west to east late Tuesday night, and become widespread Wednesday through Wednesday night, with the potential for several slow moving bands of heavy rain/embedded thunderstorms occurring. The latest WPC Day 3 Excessive Rain Outlook (for 12Z/Wed-12Z/Thu) has the entire region (eastern NY/western New England) within a Slight Risk for Excessive Rainfall, with a Moderate Risk for portions of the eastern Catskills and extreme western Mohawk Valley. Flash flooding will be possible, especially should any convective elements train over any one particular area during this time. It will remain warm and humid, with lows mainly in the mid 60s/lower 70s, and highs generally mid 70s to around 80, limited by extensive cloud cover and rain. && .LONG TERM /THURSDAY THROUGH SUNDAY/... The northern stream piece of the remnants of the upper energy and associated upper trough axis currently extending from the Great Lakes south to the Gulf Coast pushes east of our region through the day Thursday. Mid level drying spreads east across our region but as it does, scattered showers and thunderstorms will develop ahead of the leading edge of the midlevel drying. There will likely be only limited drying at the surface with the weakening upper energy and still some semblance of a broad upper trough over our region. There should be some periods of sun Thursday outside of the scattered showers and thunderstorms. Highs Thursday solidly in the 80s but some mid 70s to around 80 in higher terrain. Stronger upper energy approaches from southern Canada and just north of the Great Lakes by Friday and Saturday. A better defined cold front is expected to track through the region sometime either Friday or Friday night. The low level forcing and instability ahead of the front will support more scattered showers and storms. There is some disagreement in sources of guidance as the exact timing of the cold front. So, keeping scattered showers and storms through Friday night and isolated showers and storms Saturday. Highs Friday well into the 80s except mid 70s to around 80 higher terrain. Highs Saturday a couple of degrees cooler then on Friday. There is loose agreement on another upper system approaching our region from the west by Sunday, which would continue the chances for isolated showers and storms. Highs Sunday in the upper 70s to lower 80s but a few mid 80s southern areas and lower to mid 70s higher terrain. && .AVIATION /12Z MONDAY THROUGH FRIDAY/... Fetch of deep moisture streaming from south to north will persist through tonight. Areas of showers and isolated thunderstorms will track north through the region through tonight. Current area of showers on radar will affect all TAF sites this morning but there are breaks in the clouds and some VFR ceilings and visibilities outside of the showers. Indicating MVFR ceilings and visibilities in the showers. Once these showers exit, there should be a period of less coverage late this morning to early afternoon, perhaps 16Z-18Z. Any development of new showers and isolated thunderstorms this afternoon should increase in coverage, so including a period of TEMPO between 18Z-22Z when the best chances for the rain should be. The all day and night coverage of showers and isolated thunderstorms suggests keeping VCSH at all TAF sites during the entire TAF period ending 12Z Tuesday. Once thunderstorms develop, they can be tracked and specific timing of VFR/IFR conditions and thunder can be added. Coverage of rain should decrease to scattered tonight but MVFR ceilings should dominate. Not including any TEMPO for MVFR visibilities since rain coverage should again, be more scattered. Southeast winds today at around 10 Kt developing through this morning with possible gusts to near 20 Kt at KALB. Southeast winds continuing through this afternoon, the decreasing to less than 10 Kt tonight. Outlook... Tuesday Night: High Operational Impact. Likely SHRA...TSRA. Wednesday: High Operational Impact. Likely SHRA...TSRA. Wednesday Night: High Operational Impact. Definite SHRA...TSRA. Thursday: Moderate Operational Impact. Scattered SHRA...TSRA. Thursday Night: Low Operational Impact. Isolated SHRA...TSRA. Friday: Moderate Operational Impact. Scattered SHRA...TSRA. && .FIRE WEATHER... A tropical air mass will remain in place through at least Wednesday, as a frontal system remains west of the region, while high pressure remains anchored across the north Atlantic Ocean into New England. Weak disturbances tracking northward will bring some showers and thunderstorms through midweek, with the greater coverage expected today, and then again Wednesday. The frontal boundary should move east of the region Thursday, bringing some relief from the oppressive humidity levels. The RH values will lower 65 to 85 percent this afternoon, then rise to 90 to 100 percent late tonight. The winds will be south to southeast at 10 to 20 mph today, and only diminish to 5 to 15 mph tonight. Locally heavy rainfall is possible today into the mid week, with the most widespread rainfall expected Wednesday and Wednesday night. && .HYDROLOGY... Unsettled weather impacts the Hydro Service Area /HSA/ through most of the week. A slow moving cold front approaching from the west, along with several weak disturbances moving northward within a very moist airmass in place, will lead to scattered showers and isolated thunderstorms, some with locally heavy downpours for today. Rainfall amounts will greatly vary from a tenth to a half an inch in some spots with localized one inch or greater amounts especially, south the Capital Region, and near the eastern Catskills. The front may stay far enough west due to high pressure building in from the western Atlantic Ocean for the better coverage of showers and thunderstorms being west of the Hudson River Valley Tuesday. A potential will exist for training showers/thunderstorms that would result poor drainage flooding or an isolated flash flood if heavy rainfall repeatedly occurs over the same areas of the HSA Monday to Thursday time fame, with the best potential Wednesday into Wednesday night as the frontal boundary slowly approaches from the west and moves across the region. The ALY HSA river and stream levels are below normal and our recent dry conditions are noted in the latest drought monitor with D0-D1 levels. However, intense rainfall rates and repeated locations getting large amounts of rainfall over the next 3 or 4 days will need to be monitored. A drier air mass will likely build in toward the weekend.

Isolated thunderstorms with locally heavy rainfall will be possible through this evening, which may cause ponding of water on roadways and poor drainage flooding in low lying and urban areas for a few spots. Isolated flash flooding is possible, especially in any areas where multiple rounds of thunderstorms occur. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday. Isolated thunderstorms will remain possible Tuesday, especially across the western Mohawk Valley and southwest Adirondacks. Thunderstorms may contain locally heavy rainfall, with a very humid air mass remaining in place. There is a better chance of thunderstorms Wednesday through Wednesday night as a cold front slowly moves through the region. Some of the thunderstorms will contain very heavy rainfall which may cause small stream, urban and poor drainage flooding. Flash flooding will be possible. There is also a chance of thunderstorms on Friday. .SPOTTER INFORMATION STATEMENT... Spotter activation is not expected at this time.
