Heavy Storm Predicted for the New York Area; Improving Weather Conditions for the Rest of the Week

Bryan Dijkhuizen

Surface low pressure will travel across the area today, passing far to the southeast of the region and bringing light snow, with very moderate accumulations, to the higher terrain of the Southern Tier, Finger Lakes, and eastern Lake Ontario region.

Temperatures will rise throughout the remainder of the week, with temperatures nearing or above average on Thursday and Friday in particular. A heavier storm system is predicted to affect the region Friday night through Saturday morning, with the possibility of heavy snow in the forecast.

Regional radar shows a huge swath of precipitation, mostly in the form of snow, extending from Pennsylvania through western and central New York State and beyond.

The combination of marginal surface temperatures and mid-level dry air to the north and west has resulted in just a few inches of snow, which has been restricted to the higher terrain of the western Southern Tier and Finger Lakes.

During the next several days, snow will leave to the east and brush North Central New York, while regions to the northwest will stay mostly dry.

This afternoon, a surface low pressure system will move over the Virginia Piedmont and into the Mid-Atlantic area.

Warm air advection from the Gulf of Mexico, along with increased moisture from the atmosphere, has resulted in widespread precipitation ahead of an incoming shortwave trough. Snow is forecast throughout the afternoon in the western Southern Tier and Finger Lakes area of western New York. The back edge of the snow has become more intense, and visibility has decreased across the western Southern Tier.

This will move eastward, bringing further snow accumulations of 1-2 inches, mostly at higher altitudes, with it.

A low pressure system will guide the surface low eastward, with snow expected to finish throughout most of the area by nightfall.

As a result of surface high pressure in New England and dry air spreading throughout the area, the northern extend of snow has been restricted, with generally dry weather along I-90 between Buffalo and Rochester this afternoon. Because of the eastward movement of the surface low later today, snow will finish throughout western New York and arrive in the southern Tug Hill area by late this afternoon.

Given the time of day and temperatures in the mid to upper 30s, with temperatures reaching as high as 40 in some places, little to no accumulation is forecast north of the higher terrain in the western Southern Tier and Finger Lakes regions. It is estimated that 1-3 inches of snow may accumulate throughout the higher hills.

Overnight, a surface ridge axis will move into the area, bringing rain and snow. Clearing will occur throughout the first part of the night, with mid-high level clouds returning towards the early of Thursday morning. Low temperatures will be in the mid- to upper-20s on Sunday and Monday night.

High pressure continues to prevail throughout the area, resulting in continued dry weather into Thursday night. Thursday and Thursday night will be mostly overcast. Weather conditions are expected to improve Thursday, with temperatures rising into the high 30-to-low-40s and falling into the low-to-mid-20s Thursday night.
