A few thunderstorms could produce heavy downpours and gusty winds. More scattered strong to severe thunderstorms are possible on Thursday, along with locally heavy rainfall. Dry weather is expected to return on Friday and for most of Saturday before more rain showers are expected to move in Saturday night through Sunday.-- End Changed Discussion --&& .NEAR TERM /THROUGH THURSDAY NIGHT/...-- Changed Discussion --225 PM Update: After a hot and humid day today, a potent shortwave will move through the region this evening. Ahead of this shortwave, a few thunderstorms have developed across parts of Western NY and may clip parts of the Finger Lakes Region by the late afternoon. That being said, the bulk of the activity will likely occur this evening with better forcing from the shortwave itself and a MCV moving through. Elevated PWATs (1.75"-2.00") along with modeled soundings showing long, skinny CAPE and deep warm cloud depths will result in possible flash flooding, particularly across parts of the Wyoming Valley in Northeast PA. A Flood Watch has been issued for Wyoming, Luzerne, and Lackawanna counties for 5PM this evening to midnight. In addition there is a risk for a few isolated stronger to potentially severe thunderstorms this evening, but relatively weak lapse rates and modest shear will likely limit this potential. Thursday will feature more active weather as a cold front will move into the region. Ahead of this front, it will be very warm and humid once again (highs in the mid 80s to near 90), although most likely just under Heat Advisory criteria. Leftover morning showers from tonight`s batch of rain will result in some morning clouds, but the expectation is that these clouds will dissipate by the late morning or early afternoon. Ahead of the cold front, there will be in excess of 1500 J/kg of CAPE and 0-6km shear increasing to 25-35kts. Lapse rates will steepen as well. Hodographs show the potential for some rotating thunderstorms, with isolated supercells possible ahead of the cold front. Damaging winds and hail would be the main threats, but an isolated tornado cannot be ruled out. One area of uncertainty is if clouds from morning convective debris keep the environment a bit more stable heading into the afternoon. Any lingering showers quickly end Thursday evening following the passage of the cold front as drier and cooler air advects into the region. Lows are expected to be in the mid 50s to mid 60s.-- End Changed Discussion --&& .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... 110 PM Update... High pressure keeps conditions pleasant and dry for all of Friday and the majority of Saturday. Zonal westerly flow helps to keep things calm, while slightly dividing up high temperatures, with low to mid 70s expected for Central NY and mid to upper 70s for NE PA on Friday. For Saturday, high pressure remains for the majority of the day, except with zonal flow being disrupted with lower level flow turning more southwest. Warm are advection allows for temperatures to increase into the low to mid 80s for the majority of areas, with higher elevations possibly in the upper 70s, and valley locations a little warmer than the mid 80s. A disturbance moving west to east over the Great Lakes region will move into our area heading into Saturday afternoon and evening, bringing showers and storms for the entire area potentially through the night and into a portion of the long term period. Currently, these storms lack CAPE but show some 0-6 km bulk shear and mid- level lapse rate values that could help these storms become severe, but confidence is too low currently to determine how strong these storms could be, especially with the lack of CAPE in model guidance. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... 110 PM Update... As mentioned in the short term period, showers and storms could potentially continue into the daytime on Sunday. Overhead ridging and surface high pressure from the north pushes down into the area Monday, resulting in a likely beautiful, precipitation free day for Monday. At the very end of the long term period, guidance gets very divided, where high pressure may stick around for Tuesday, or the next system comes in slightly earlier with showers in the afternoon. We`ll keep an eye on the progression in the coming days. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/...-- Changed Discussion --Mainly VFR conditions are expected through this evening, but brief restrictions will be possible in any heavier shower or thunderstorm that may more through. After the showers and thunderstorms depart, MVFR ceilings are expected to move into KITH, KBGM, and KAVP. With rain moving through KELM, fog should develop, with IFR conditions developing after 08z tonight. Conditions return to VFR by mid-late morning on Thursday. Outlook... Thursday afternoon...Restrictions likely with a few rounds of showers and thunderstorms. Friday through Saturday...Mainly VFR. Sunday...Occasional restrictions possible in showers and thunderstorms. Monday...Mainly VFR.-- End Changed Discussion --&& .BGM WATCHES/WARNINGS/ADVISORIES...-- Changed Discussion --PA...Flood Watch from 5 PM this afternoon to midnight EDT tonight for PAZ043-044-047.
