Winter storm to hit upstate NY this weekend. Here's what to expect
Hunker down. A wintry weekend is straight ahead in western New York - with some predicted snow, freezing rain and rain on the horizon, according to the National Weather Service in Buffalo.
While forecasters were not yet able to pinpoint just how much snow New Yorkers will see, Weather Service Meteorologist Tony Ansuini said to expect "plowable amounts" - at least several inches of snow - this weekend as "quite a messy storm system approaches."
Ansuini said to expect widespread snow starting Saturday morning through at least Saturday evening. Warmer air will cause the snow to transition into a wintry mix with freezing rain and regular rain on Sunday before it again becomes colder and transitions back to snow later on Sunday.
The timing of the snow and shades of rain/freezing rain in the Rochester region is not yet clear, Ansuini said, as the storm is approaching New York and the system could shift. As of Friday morning, the storm is tracking to bring more snow to the north (including the Watertown area) and more rain and freezing rain in the Southern Tier.
The Weather Service issued a winter storm watch from Saturday afternoon to Sunday evening for Oswego, Jefferson and Lewis counties. Up to a foot of heavy lake effect snow and up to a quarter-inch of ice is expected in Oswego County. More than 6 inches of snow and up to a quarter inch of ice is predicted for Jefferson and Lewis counties.
Wind gusts are expected to reach 35 mph, which could create hazardous driving conditions, forecasters said.
Additional alerts are expected later today, Ansuini said.
A winter weather advisory is set to run for 24 hours, starting at 9 a.m. Saturday in Onondaga County, where 4 to 9 inches of snow is predicted to fall in communities north of the Thruway in that timeframe, and 3 to 6 inches of snow is predicted to fall elsewhere.
A winter weather advisory was also issued for Yates, Seneca, northern Cayuga, Steuben, Schuyler, Chemung and Tompkins counties during the same timeframe. There, 2 to 5 inches of snow and up to two-tenths of an inch of ice is predicted.
The advisories for Madison, Chenango, Otsego, Delaware and Sullivan counties runs from 11 a.m. Saturday to 1 p.m. Sunday. In Madison County, 5 to 10 inches of snow is predicted in that timeframe and 3 to 5 inches of snow is predicted in the other counties. Up to three-tenths of an inch of ice is also predicted in all five counties.
Currently, a lake effect snow warning is underway in Oswego and northern Cayuga counties through 1 a.m. Saturday.
Herkimer County, where up to 4 inches of lake effect snow is predicted to fall Friday, remains under a lake effect snow warning until 7 p.m. Friday.

Severe storms possible across Maryland this evening; Alert Day in effect
A Tornado Watch has been issued for areas south and west of Baltimore through 10 p.m. Sunday evening, as the atmosphere becomes increasingly unstable ahead of an approaching warm front. The watch includes portions of central Maryland, southern Maryland, and the Lower Eastern Shore, where the threat for severe weather will be highest. The warm front is expected to lift northward toward the Baltimore metro area by Sunday evening. As it does, it will separate two distinct air masses: cooler, more stable air to the north, and warm, humid, unstable air to the south. Areas south of this front will be firmly entrenched in a favorable environment for the development of strong to severe thunderstorms, including isolated tornadoes, damaging wind gusts, small hail, and torrential downpours. The highest threat zone extends south of a line from Gaithersburg to Annapolis to Easton to Cambridge, encompassing a wide portion of the state. This includes the southern suburbs of Washington and Baltimore, as well as St. Mary's, Calvert, Charles, Talbot, Dorchester, and Wicomico counties. Although storms could occur anywhere in Maryland, the greatest concentration of dangerous weather is expected in these southern and eastern zones. Meteorologists warn that any storms that interact directly with the warm front could rotate and briefly produce a tornado, particularly given the enhanced low-level wind shear present along the boundary. Frequent lightning and flash flooding will also be concerns with any slow-moving cells, especially in areas that have seen recent rain. By midnight, the severe threat should diminish as storms lose daytime heating and the atmosphere begins to stabilize. Overnight conditions will turn quieter with partly to mostly cloudy skies and lows remaining mild, generally in the mid to upper 60s. Unsettled Start to the Week Monday will start off dry for many, with a mix of sunshine and clouds through the morning hours. However, the break will be brief. Another round of storms is expected to develop by late afternoon and continue into Monday night. The Storm Prediction Center has placed much of the region under a Marginal Risk for severe storms Monday, with the potential for damaging winds and locally heavy rain once again. Temperatures on Monday will climb into the low to mid 80s, adding additional fuel for afternoon convection. Cold Front Arrives Tuesday A stronger cold front will approach and move through the region on Tuesday. The best chance for showers and storms will come during the morning hours, especially east of I-95, as the front sweeps eastward. Behind the front, slightly drier and more comfortable air will begin to filter into the region, though temperatures will remain warm with highs in the low to mid 80s. The passage of this front will mark the beginning of a brief stretch of quieter weather midweek. Warm and Sunny Midweek Forecast High pressure will build in from the west on Wednesday and Thursday, leading to a period of dry and mostly sunny weather. Afternoon highs will approach 90 degrees, especially on Thursday, with noticeably lower humidity and overnight lows dropping into the 60s. This will likely be the most pleasant stretch of the week, offering a break from the repeated thunderstorm chances that have affected the region since the weekend. Stormy Pattern Returns for Father's Day Weekend By Friday, another cold front will begin to approach from the west. Increasing moisture and instability ahead of the front will lead to a renewed chance for scattered storms, especially Friday afternoon and evening. Unlike earlier in the week, this front is expected to slow down or stall across the region, leading to prolonged rain chances that may persist through the weekend. As a result, both Saturday and Father's Day on Sunday could feature periods of showers and thunderstorms, with locally heavy rain possible at times. Temperatures will trend cooler as clouds and rainfall become more persistent. Highs on Saturday and Sunday are expected to fall back into the mid to upper 70s, a noticeable change from the summerlike warmth earlier in the week.

At least 2 people killed as storms push through South
Two people were killed by falling trees and tens of thousands were left without power as severe storms rolled through the South over the weekend. The storms downed trees and powerlines and brought heavy rainfall, hail and gusty winds as they pushed through the region. Nearly 150,000 people across southern states from Texas to South Carolina were without power Sunday morning, according to Mississippi Gov. Tate Reeves said one person was killed in Lafayette County when a tree fell on a vehicle. Multiple tornado warnings were issued across northern Mississippi on Saturday. Georgia Gov. Brian Kemp said one person was killed in Georgia on Saturday night. A spokesperson for the Georgia Emergency Management said the fatality occurred in Banks County when a tree fell on a vehicle. 'Join us in praying for the loved ones of a Georgian tragically lost tonight due to the severe storms,' Kemp wrote on social media. The National Weather Service said a confirmed EF-1 tornado damaged multiple homes and injured one person Friday in the city of Van Buren in western Arkansas. Another round of severe weather is expected to push through the southern Plains and the South on Sunday evening and Monday. The highest risk for severe weather is in southwest Oklahoma and northern Texas. The National Weather Service said destructive wind gusts of up to 100 miles per hour, giant hail up to five inches in diameter and a few tornadoes are likely.
