It will be mainly dry today with plenty of sunshine across the area. Temperatures will be on the rise, reaching the upper 80s and low 90s this afternoon and again on Monday. A more active weather pattern returns early this week with a chance for showers and thunderstorms Monday and Tuesday, before drier weather arrives on Wednesday. && .NEAR TERM /THROUGH MONDAY/... 220 AM Update Strong upper level ridging through the near term will lead to increasing humidity and temperatures in the near term period. Anticyclonic flow and upper level ridging will be over the region today. Can`t rule out a stray shower or t`storm across the NY thruway corridor or southern Tug Hill plateau, otherwise it will be dry and mostly sunny for the rest of the CWA. Low level moisture is starting to increase, with surface dew points expected to be in the 60s this afternoon. These elevated dew points will combine with high temperatures in the upper 80s to low 90s to produce high heat indices in the mid to upper 90s in the valley locations. Heat advisories remain in effect, for the Finger Lakes, Syracuse metro area, and now expanded into Madison/S. Oneida county from late this morning through early this evening. Heat advisories may need to be extended in time through Monday for at least some locations...but there is uncertainty with cloud cover and how that could impact temperatures Monday. Dew points will be higher Monday, in the low to mid-70s so it will feel extremely muggy out there. Quiet tonight, with partly cloudy skies and muggy overnight lows in the mid-60s to lower 70s expected. Monday starts off mainly dry, but clouds increase and eventually showers and thunderstorms become likely by the afternoon and evening hours. PWATs will be quite high over the NW half and far SE portion of the forecast area...between 1.8 to 2.1 inches. These high pwat values will combine with MUCAPE values between 1500-3000 J/kg to produce locally heavy rainfall in thunderstorms. The remnants of Tropical Storm Chantal will be potentially enhancing the rain and t`storm potential as a slow moving front sinks SE across the area late in the day. WPC has our area in a marginal risk for excessive rainfall and isolated flash-flooding...this will certainly be something to watch closely over the next day or two. SPC also has a marginal risk for isolated severe storms with damaging winds, across the NW half of the CWA Monday afternoon & evening. Soundings show 3000 J/kg of SBCAPE, 25 kts of 0-6km shear and over 1000 J/kg of DCAPE...so we will need to watch for any better organized storms that may produce strong, gusty to isolated damaging winds. && .SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/... 230 AM Forecast... The frontal boundary will slowly slide SE through the CWA Monday night. The ridge over the Atlantic will more than likely strengthen from the latent heat release from the remnants of Tropical Storm Chantal, which will push the parent low north while the trough elongates to the SW and the front slows its forward motion. Luckily, guidance currently has the remnants of Chantal staying to our SE ahead of the front and moving into southern New England Monday night. There is however a ribbon of tropical moisture from the western Gulf that will ride the western edge of the ridge and move into the area ahead of and along the front. PWAT values will approach 2in across CNY and NEPA Monday night as the front slowly moves through. MBE vectors are short, meaning storm motion will be slow with a high chance for back building of storms along the front. Warm cloud rain processes; deep warm cloud layers (>10k feet) and long, skinny CAPE profiles, all point to possible high rain rates with storms that develop. 1-3 inches will be possible in these storms, with the NAM currently showing a swath of 2-3 inches of rain moving through the Finger Lakes into NEPA Monday night. This is a bit of an outlier at this time, but the signal is there for heavy rain so we must continue to watch it closely. Tuesday looks to be cooler for NY as the front is progged to be somewhere over N NJ into eastern PA. Highs will be in the mid 70s to low 80s for NY and mid 80s closer to the front across the Catskills into NEPA. CAPE around 1500j/kg with 0-6km bulk shear around 25kts will allow for some strong storms to develop, and combined with PWATs approaching 2in, heavy rain and isolated flash flooding will be possible over the Catskills into NEPA late Tuesday morning into the evening hours. The front should slide east Tuesday night, ending the heavy rain threat. Lows Tuesday night will be in the upper 50s to low 60s. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... 300 AM Forecast... High pressure builds in behind the front, keeping Wednesday dry. Temps increase as heat builds in from the south with highs in the mid to upper 80s across the region. The rest of the week will see temperatures in the upper 70s to mid 80s, but dewpoints will remain elevated in the 60s so it could feel a little muggy at times. A troughing pattern returns for the end of the week, with showers and storms developing Thursday, Friday and Saturday. The latest run of the GFS shows a ridge moving into the Canadian maritimes at the end of the week, which would keep a lot of the rain to our south and bring cooler temps to the area. Euro and GFS ensembles are showing hints of this so we will be monitoring the evolution of the pattern. && .AVIATION /17Z SUNDAY THROUGH THURSDAY/...-- Changed Discussion --VFR through the TAF period at most taf sites. A marine cloud layer looks to develop over the Poconos and expand northwestward early Monday morning. At the very least, MVFR CIGs will move into AVP early Monday morning and could drop below 1K feet for a brief period. This MVFR cloud layer gets close to BGM around or just after daybreak, but climatology points to this likely ending up just east of BGM before starting to erode Monday morning. Outlook... Monday afternoon...Scattered showers and thunderstorms possible, with associated restrictions, especially at SYR. Tuesday through Wednesday night...Mainly VFR with a chance for showers or a thunderstorm. Thursday... Restrictions possible with some showers and thunderstorms.-- End Changed Discussion --&& .BGM WATCHES/WARNINGS/ADVISORIES...-- Changed Discussion --PA...None.
