A cold front will sweep across our region this evening, with rain showers and still gusty southwest to west winds through the evening hours. Behind the front showers will end from west to east...with our region dry by around 12Z Sunday morning. KEY MESSAGE 2...Next chance for rain/storms arrives Tuesday night and Wednesday, before possibly ending as some mixed precipitation or snow. A dry period expected Sunday through Tuesday with a day to day warming trend and above normal temperatures for early March. The next chance for rain/storms arrives Tuesday night and Wednesday. Current guidance suggesting that a northern stream shortwave may try to phase with a southern stream closed low locked into the four corners region. This wave then moves eastward into the region during the Tuesday night and Wednesday time period. Ensembles are in decent agreement on this solution and bringing chances for rain and possible thunderstorms to the region. Deterministic guidance pointing to strong high pressure over eastern Canada possibly forcing a backdoor cold front south into the region Wednesday night and Thursday. This could bring cooler temperatures and a potential risk for mixed precipitation or snow, but there is a fair amount of uncertainty among long range ensembles on the depth of the trough and timing. Majority of GEPS members are slightly slower or less sharp with the upper level trough compared to EC and GEFS members. Regardless, most guidance suggests 850mb temps will dip towards -10 to -14 degC by late next week after being above the climatological 90th percentile for the first half of the week. KEY MESSAGE 3...There remains a low-end threat for flooding through next week, mainly across the North Country, as a result of above normal temperatures and multiple rounds of rain. Above normal temperatures along with long range ensemble guidance and WPC forecast showing an additional 1-2.5" of QPF across the eastern Great Lakes over the next 7 days. This pattern will lead to rises on most area waterways with an increased threat for flooding as the rainfall combines with accelerated snowmelt runoff. Based on the limited amount of SWE and antecedent water levels being low, the threat for flooding should be very limited for the waterways across western NY. However, numerous creeks are forecast to crest in Action stage, though are expected to remain below flood stage this weekend. The few exceptions continue to be the Tonawanda Creek at Batavia and at Rapids looking to crest at Minor flood stage Sunday morning and Monday, respectively. A different story east of Lake Ontario as recent SWE surveys have measured over 10" of liquid in the snowpack across the Tug Hill. This could lead minor flooding along the Black River and other rivers (Beaver, Independence, and Moose) that drain the western Adirondacks and Tug Hill Plateau. MMEFS guidance suggests water levels on the Black River should continue to rise through the weekend, cresting near the middle of next week. Still some discrepancy in regards to maximum crest height on the Black River (Watertown and Boonville), though aside from the typically bullish NAEFS, there is only a low (15% chance or less) chance to reach flood stage. While a slow rise to Action stage appears to be the most likely scenario, will need to continue monitoring trends.-- End Changed Discussion --&& .AVIATION /00Z SUNDAY THROUGH THURSDAY/...-- Changed Discussion --For the 00Z TAFS a cold front will sweep across our region through about 09Z with rain showers ending from west to east. Still gusty winds upon the front...and for when stronger gusts are not mixing down to the surface there will likely remain LLWS around 1500 feet. Through the night, as the cold front passes through Buffalo and Niagara Falls a southwest wind may advect the marine layer inland, with ceiling heights and visibilities lowering to IFR. Elsewhere through the night we could see a few hours of IFR flight conditions with a cooler airmass over the still saturated ground from recent rains. Sunday, areas of low stratus with MVFR and IFR flight conditions will persist into the morning before improving to mainly VFR by midday to early afternoon as much drier air advects across our region. It will become quite windy again from late morning through afternoon with gusts in the 25 to 35 knot range, strongest northeast of Lake Erie. As these gusts diminish with the lowering of the boundary layer height late tomorrow afternoon and evening, another 50 knot low level jet, with a base around 1500 feet will bring renewed chances for LLWS. Outlook... Monday...VFR. Tuesday...Mainly VFR with a chance of showers in the afternoon. Wednesday through Wednesday night...MVFR/IFR with occasional rain showers. Chance of a few isolated thunderstorms. Windy Wednesday night. Thursday...Areas of MVFR with snow showers likely. Windy.-- End Changed Discussion --&& .MARINE...-- Changed Discussion --Low pressure will move northeast across Quebec this evening, with a trailing cold front crossing the lower Great Lakes. Moderate to strong SSW winds will produce Small Craft Advisory conditions on Lake Ontario and Lake Erie through much of tonight. There will be a brief period of somewhat lower winds late tonight and early Sunday morning before southwest winds increase again Sunday bringing small craft advisory conditions back to all waters. A similar trend will occur Monday, with a brief early morning lull in winds before southwest winds increase again through the daytime. Winds will diminish Monday night through Tuesday. Please note...most, if not all of the Lake Erie nearshore waters continue to be ice covered. Waves have been omitted from the forecast.-- End Changed Discussion --&& .BUF WATCHES/WARNINGS/ADVISORIES...-- Changed Discussion --NY...None. MARINE...Small Craft Advisory until 10 PM EST Sunday for LEZ020-040-041. Small Craft Advisory until 10 PM EST Monday for LOZ042-043. Small Craft Advisory until 4 PM EST Monday for LOZ044-045.-- End Changed Discussion --&& $$ DISCUSSION...Brothers/PP/Thomas/TMA AVIATION...Thomas MARINE...Hitchcock/Thomas
