1245 AM Update: Main change with this update was to remove any mention of thunder from the forecast for the overnight hours. In fact, the majority of the showers have dissipated, with just a few isolated sprinkles/light showers around. 720 PM Update... Forecast remains mostly on-track with just some minor changes made to PoP based on latest RADAR and CAMs to adjust for coverage and timing of rainshowers tonight. 250 PM Update... Showers and thunderstorms associated with a lake breeze boundary have been slowly drifting south. Suspect these will mainly decrease in intensity over the next hour or two given weak instability and diminishing lake influence. However, a shortwave trough over southern Ontario will provide forcing for a more organized batch of showers and thunderstorms which will sweep NW to SE across the area this evening. Again, limited instability will limit thunderstorm coverage, but precip coverage looks to be fairly high across CNY, then diminishing as you head SE into NEPA. Overnight will be mostly cloudy, but with fresh rainfall, patchy fog will be possible, especially in any valley areas which happen to see some breaks in the cloud cover. A spotty shower or two can`t be ruled out through the night. Cyclonic flow continues on Monday, but the stronger forcing will be shifted east of New England. The trailing edge of a shortwave trough could kick off a shower or two across CNY in the mid- afternoon, but it`s looking to be a mostly dry day. Cloud cover, however, will be tough to break up as forecast soundings show nearly saturated conditions between about 925-800 mb or so, trapped beneath a stout inversion. The drier air further aloft will also help reduce the shower threat in addition to the weak upper level forcing. Monday night looks dry, with light winds, but again the cloud cover might try to hang on, reducing the risk of valley fog.

&& .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... 250 PM Update... An upper trough gradually departing the area Tuesday can lead to a couple of showers popping up in the afternoon over the Catskills and Poconos, otherwise, it will be a quiet day with some sunshine. Temperatures will still be running below average, but not a cool as Monday with highs from the mid 60s to near 70 degrees. Lows will be from the mid 40s to the low 50s at night. High pressure at the surface and aloft builds in Tuesdsay night and is expected to remain in control through Wednesday night promoting dry conditions. Wednesday will be a pleasantly warm day under partly to mostly skies and with winds becoming WSW, temperatures return to the mid and upper 70s. Wednesday night won`t be quite as chilly with lows in the mid to upper 50s. && .LONG TERM /THURSDAY THROUGH SUNDAY/... 250 PM Update... The warming trend continues Thursday into Friday as southwesterly flow remains in place and temperatures range from the upper 70s to the mid 80s with some valley locations hitting the upper 80s. As the upper level ridge aloft begins to shift east and the flow becomes more zonal, there is a slight chance of a shower Thursday, mainly over north-central NY, with a weak shortwave passing near the area, otherwise a partly sunny day is expected. Friday into Friday night will be the next chance of showers and thunderstorms, however there are some timing differences with the next upper trough and associated surface cold front that is expected to move through. The 12Z run of the GFS has come in slower with the cold frontal passage than the 00z run, coming more in line with the 00Z Euro and 12Z Canadian favoring later in the afternoon or evening, but this will be monitored. PWATs do look to top out around 1.50 inches across the area, so there could be some embedded heavier downpours. Drier air is expected to move back in for the weekend in the wake of the front with a brief dip in high temperatures Saturday. && .AVIATION /06Z MONDAY THROUGH FRIDAY/... A band of showers and embedded (isolated) thunderstorms will push through Central NY tonight. Brief MVFR ceilings and visibilities close to IFR will be possible as they push through the region, with showers diminishing in intensity as they move into NE PA later tonight. MVFR ceilings behind the organized showers will slowly drop into fuel alt range, with IFR possible Monday morning. Highest confidence for IFR ceilings is at BGM, ITH and RME. Ceilings will be rather slow to rise on Monday with low level moisture lingering into the afternoon hours. Outlook... Monday night through Thursday...Mainly VFR. Friday...Restrictions possible in showers and thunderstorms. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
