Area Discussion for - Buffalo, NY
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kbuf 202325 afdbuf area forecast discussion national weather service buffalo ny 625 pm est Wed feb 20 2019 Synopsis A light wintry mix of precipitation will develop this evening and gradually transition to rain overnight as warmer air arrives. This will end by early Thursday morning as a cold front slides through the area. High pressure will return for the rest of the work week before a much stronger system arrives this weekend. Rain will be common by Saturday night before a very strong cold front likely brings very strong, damaging winds on Sunday. Near term through Thursday The first wave of upper level moisture and warm advection is spreading into the north country early this evening with some spotty light snow. Any accumulation will be minimal as this area of light snow continues to erode as it moves into a dry airmass ahead of the system. There is a break behind the initial area of light snow from the genesee valley into the western finger lakes and points southeast of lake ontario. The next round of steadier precipitation is moving into chautauqua county, and this will quickly overspread the area this evening. This next round of precipitation is associated with a deeper wave and will bring much more widespread precipitation than the initial wave. Temperatures are at or just above freezing along the lake erie shore northeastward to buffalo and niagara falls, and temperatures will continue to rise with the arrival of the next batch of precipitation as southeast downslope winds and warm advection continues. This will allow most of the precipitation to fall as rain along the lake erie shore to the buffalo metro area. Inland and farther east the near surface cold air will likely hold long enough to support a brief period of freezing rain at the onset, with the longest period of freezing rain across the colder valley locations of the western southern tier and also east of lake ontario. Any ice accumulation will be very light in most areas, but may reach a tenth of an inch across the southern tier valleys and a few valleys in the western finger lakes and east of lake ontario. All of this will change to rain overnight from west to east as warmer air spreads into the region, and any ice that does accumulate will melt. A cold front slices through the area on Thursday with some gusty winds in its wake. Temperatures will likely MAX out early in the day as cold advection starts. So with little upward temperature mobility and gusts to 35 mph or so, it will feel colder than it likely will be for much of Thursday. Short term Thursday night through Saturday night Generally zonal flow and slowly rising mid level heights through Friday night, as weak upper ridging and accompanying surface high pressure slide through the region. This pattern will ensure dry weather across the region. The only exception may be early Thursday night as some lingering light precipitation will be possible east of lake ontario, primarily focused on the higher terrain of the adirondacks. The respite from precipitation will come to an end later Saturday and Saturday night. A dynamic upper level wave trough will track through northern mexico on Friday, with rapid cyclogenesis taking place over the central plains on Saturday. It looks like some additional upper level energy coming out of the pacific northwest will help deepen the storm to 980 mb or lower as the system tracks through the upper midwest to the western great lakes through Saturday night. As this occurs, a significant amount of moisture will be transported northward back into the eastern great lakes. While the day on Saturday for the most part looks dry, clouds will increase and thicken from the south during the course of day. Some patchy light rain could reach far western new york by the end of the day. A milder day is expected with temperatures warming into the 40s, perhaps nearing 50f over the western counties. Rain will eventually overspread the entire region Saturday night as low level moisture transport accompanies a northward moving warm front. Long term Sunday through Wednesday Widespread damaging winds likely Sunday... a very strong storm system will move across the central great lakes and into quebec Sunday-Sunday night. Model guidance continues to show a favored track for western and north central ny to receive widespread high, damaging winds. The past few model runs of the gfs has lowered the central pressure to 974mb as it tracks to the northwest, which is now close to the ecmwf. With these two global models in good agreement, this far out, confidence is moderate-high that the region should see a high wind event Sunday-Sunday night. Going into the details, a mid-level trough with a 1.5 mb pv intrusion will be following the strong surface low pressure as it |
cuts the great lakes. This will cause the low to slow its deepening process as it moves into eastern canada. This won't really matter in the potential for high winds as a strong low-level jet will already be across western ny by Sunday morning. The core of the low-level jet will likely move across western ny and into north-central ny by afternoon. At this point, a cold front will be moving across the region while southwest 925-850mb winds align. Strong subsidence with lapse rates around 9 deg c km will mix gusts to 55 to 65 mph starting at some point Sunday and continuing into the evening. This prolonged period of strong gusts will cause widespread wind damage if they pan out. Please keep in mind though that at this point... It is only a forecast... Albeit one with increasing confidence. It will be important to stay tuned to updated forecasts and possible statements headlines as we progress through the rest of the week. As a side note... The front will be accompanied by some showers on Sunday... Mainly ahead of it... And then several hours after it moves through. Winds will remain strong into Monday morning as the 6hr pressure change between the exiting strong low pressure to the north and the approaching high pressure is on the order of 10-12 mb. Gusts of 40- 50 mph will likely continue into Monday. Cold air will also being moving into the region at this time and snow showers are expected with lake enhancement south-southeast of both lakes. Minor accumulations are expected at this time. Temperatures will be above normal Sunday-Sunday night before cold air advection brings temperatures below-normal for much of next week. Aviation 00z Thursday through Monday Spotty light snow will continue through mid evening across the north country with MVFR vsby. The next round of precipitation will spread across the region from southwest to northeast this evening. This will fall briefly as freezing rain inland from the lakeshores before changing to rain overnight. Vsby will generally drop to MVFR in the steadier precipitation. Widespread MVFR CIGS will continue to develop this evening with ifr across higher terrain. The rain will taper off quickly from west to east late tonight, leaving mainly dry conditions for Thursday. The one exception may be across the higher terrain east of lake ontario where some light upslope rain and snow showers may continue through the day with local MVFR vsby. The widespread MVFR CIGS will continue through much of the day Thursday in low stratus behind the cold front. Outlook... Friday and Saturday...VFR. Sunday... MVFR or ifr with rain, then snow. Strong winds. Monday...VFR MVFR with scattered snow showers. Marine The center of a storm system will cut through the central great lakes tonight, with southeast winds veering to southwesterly tonight. While these winds will keep the higher waves over the canadian waters, the winds may flirt with small craft thresholds later today and tonight. Thursday these southwest winds will increase further, and will place SCA on the lakes through Thursday night. Winds will also reach low end SCA on the niagara river later tonight and tomorrow. A powerful storm system will cut through the central great lakes Sunday and Sunday night. As this system rapidly deepens it will produce at least gale force winds on the lakes, with storm force wind gusts likely. Buf watches warnings advisories Ny...
