Fxus61 kaly 190819 afdaly area forecast discussion national weather service albany ny 419 am edt Fri jul 19 2019 Synopsis A warm front will lift north of our region today. This will lead to dangerous heat and oppressive humidity this weekend, along with scattered showers and thunderstorms. A cold front will drop through the region on Sunday night into Monday, with a return to seasonable temperatures and lower humidity to start the new work week. Near term until 6 pm this evening Heat advisory in effect from noon Friday to noon Saturday with an excessive heat warning in effect from noon to 8 pm Saturday for the mohawk and hudson river valleys, southern taconics, and litchfield county in NW ct... clouds across the region supported by southerly flow and trapped moisture at 925 hpa but southwest to west flow above 925 hpa will mix to the surface around or just after daybreak, that will erode the cloud layer. By midday, most areas should see lots of sun and surface winds turn to southwest which is some downslope in some areas. The convective complex currently in the western great lakes is somewhat resolved in sources of guidance and the convective footprint could track toward the schoharie valley and eastern catskills by late this afternoon with new thunderstorm development. Including isolated thunderstorms late this afternoon in those areas. The Sun and the west to southwest low level flow should help temperatures get solidly into the 90s with some 80s in higher terrain. Heat index values could get up to around 100 in the hudson and mohawk valleys to NW ct. Heat index values could also get to near 100 near the vt nh border in the ct river valley, where eastern windham county was added to the heat advisory today. Short term 6 pm this evening through Sunday Heat advisory in effect from noon Friday to noon Saturday with an excessive heat warning in effect from noon to 8 pm Saturday for the mohawk and hudson river valleys, southern taconics, and litchfield county in NW ct... heat advisory has been issued for the remainder of the area from noon to 8 pm Saturday... the coverage of thunderstorms that develop in central ny and near the eastern catskills is in question and even the cams show considerable differences in opinion on coverage and timing. Including isolated to scattered thunderstorms from the schoharie valley to eastern catskills and mid hudson valley where the guidance and cams show the best consensus. Included heavy rain and gusty winds wording as there is a marginal risk for severe thunderstorms. Instability will be quite considerable this afternoon and evening and a small low level jet core near the leading edge of the deeper moisture could support a more organized convective complex than guidance suggests but it is too early to tell until daytime data and trends can be analyzed. If there is a larger and more organized thunderstorm complex, then more of a threat for damaging winds and potential power outages, power outages that prevent the use of air conditioning. This is just something to keep and eye on. Lows tonight in the 70s. Saturday, the core of the heat will be over our region and lots of Sun with continued west to southwest flow will help temperatures reach the mid to upper 90s. Dew points will reach the mid 70s and heat indices perhaps getting around 110 in some areas. There are hints in sources of guidance for another little low level jet core to track near the ny canadian border through northern new england later Saturday afternoon and night with another chance for scattered thunderstorms, mainly in northern areas. However, with the extreme instability in our entire region, some lake breeze or local terrain convergence could trigger isolated to scattered thunderstorms in other areas. Will have to watch for some sort of organized complex again but lots of uncertainty due again, to nebulous weak low level convergence. Whatever storms do form end Saturday night. Lows Saturday night in the mid to upper 70s with around 70 to lower 70s in higher terrain. By Sunday, sources of guidance ensembles show increasing differences in the timing of upper energy beginning its building south out of canada and the associated cold front. Boundary layer flow is expected to be more west to west northwest, suggesting considerable Sun and another hot day with highs well into the 90s again. There could be a prefrontal trough Sunday afternoon with better low level convergence to support scattered thunderstorms over much of the region. Then the first phase of the cold front will drop just south of our region Sunday evening. More heat headlines will likely be needed Sunday, especially in parts of the hudson valley and NW ct. Thunderstorms could be strong again with the extreme instability ahead of the upper energy and cold front. Long term Sunday night through Thursday The period starts out on Sunday night with a cold front positioned just south of our region, with a potential secondary front just upstream of the area. Most sources of guidance indicating this secondary boundary slowing down as it pushes southeast on Monday, with a wave of low pressure forecast to develop along the front. Due to this slowing trend, have extended mention of chance pops through the daylight hours Monday for the entire area, and into Monday night from around albany south and east. There is low confidence in the forecast for this time frame, as we are not seeing any real consistency in the model guidance yet. There is good agreement that temperatures will cool down by Monday, especially with clouds showers around. Highs only expected to reach the upper 70s to lower 80s in valley locations. Will mention chance thunder from around i-90 southward, but it is uncertain how much if any sunshine will occur which would limit instability. By Tuesday, the frontal system should be south and east of our region with mainly dry conditions expected. There could still be a stray shower south and east of albany, but coverage looks sparse. Humidity levels will be noticeably lower as dewpoints are forecast to drop into the 50s. Temperatures should also be slightly below normal, as a broad trough settles in across the great lakes and

northeast. Isolated to widely scattered showers will be possible Wednesday into Thursday for parts of the area, as the upper level trough axis approaches from the west. However, moisture instability will be lacking so much of the region will remain dry with seasonable temperatures and dewpoints mainly in the 50s to lower 60s. Aviation 08z Friday through Tuesday Widespread low stratus clouds have enveloped the region with a humid air mass in place, and will remain through the rest of the night into this morning. Cig heights have been in MVFR range so far, although some lowering is expected overnight, with potential for ifr CIGS at kpsf kpou. Highest confidence in ifr CIGS at kpsf, with lower confidence at kpou. CIGS at kalb kgfl should remain in MVFR range. The lower stratus clouds will gradually dissipate during the morning, with improvement toVFR expected by late morning. There is a potential for scattered thunderstorms during the late afternoon to early evening time frame at the terminals. There is low confidence in placement and exact timing, but enough to mention prob30 for tsra at all sites. Brief ifr MVFR conditions could occur within any tsra. Winds will initially be light and variable, becoming southwest around 10 kt, with occasional gusts near 20 kt this afternoon. Locally stronger wind gusts will be possible in and near any tsra.

This will lead to dangerous heat and oppressive humidity this weekend, along with scattered showers and thunderstorms. A cold front will drop through the region on Sunday night into Monday, with a return to seasonable temperatures and lower humidity to start the new work week. Rh values this afternoon and Saturday afternoon will be 50 percent or more while nighttime rh values will be 80 to 100 percent. Winds will be south to southwest today at 5 to 15 mph, near calm tonight and southwest at 5 to 15 mph again Saturday. Winds will be stronger, and variable in direction in and near any thunderstorms. Hydrology Isolated to scattered, mainly afternoon evening showers and thunderstorms will be possible through the upcoming weekend, with the most widespread coverage expected Sunday afternoon into Monday as a cold front crosses the region.
