Hurricane Harvey is expected to hit Texas as a Category 3 storm — the likes of which haven’t been seen since 1999’s Hurricane Bret — when it makes landfall late Friday or early Saturday, forecasters say. The storm strengthened to a hurricane, with maximum sustained winds of 80 mph, on Thursday afternoon. The storm’s surge could be life threatening, up to 10 feet, with waves as high as 20 feet above that. Rain is expected to range from 10 to 20 inches, and some areas could receive up to 30 inches. Perilous flash flooding and 115 mph gusts are possible. The biggest worry with Hurricane Harvey is that it’s expected to stall

The National Weather Service of Pittsburgh confirmed a downburst came through McDonald around 1:30 p.m. An afternoon of numerous thunderstorm warnings gave way to a Flood Advisory for Allegheny County in the evening hours, but that expired at 7:30 p.m. In Allegheny County, the South Hills was also hit hard with damage. They saw flash flooding, and high winds brought down trees and power lines. McDonald in northern Washington County may have seen the worst of the weather. The NWS said on their Twitter account that a downburst brought down numerous trees in the area. In other areas, trees were reported down in various places from Murrysville to Export to Harrison City

Scattered strong to severe storms remain a threat across eastern Pennsylvania into parts of New England this evening and perhaps to the early overnight. Although instability will be weakening, given the loss of daytime heating, storms will continue to spread across eastern PA into northern NJ and southeast NY to parts of New England this evening to the early overnight, as strong forcing for ascent should compensate for the weaker instability in the short term. Strongly sheared environment, as deep-layer winds strengthen into New England, will continue to favor storm organization with low-level rotation remaining possible for a tornado or two. For those who will be in the path of these

The remnants of Harvey have a near 100% at re-development according to the NHC. This storm will track towards the TX coast Friday/Saturday where it may slow down, move inland and then possibly track east back out over the Gulf. It’s too soon to determine how strong the system may get, but it may easily reach strong TS or CAT 1 hurricane status. We have issued Elevated Alert Levels for the TX coast & a portion of SW LA due to an increased risk of being impacted based on the latest data. Heavy rain and flooding are going to be a major concern with this system as it could be a

Severe thunderstorms are possible Tuesday across much of Upstate New York, southward through the Ohio Valley, accompanied mainly by the risk for potentially damaging wind gusts. In association with the deepening surface cyclone, a notable cold front is forecast to advance eastward and southward through much of the Northeast, Ohio and Tennessee Valleys and south central Plains by the end of the period. Forcing for ascent and destabilization along and ahead of this feature may support considerable thunderstorm activity Tuesday through Tuesday night, at least some of which probably will be accompanied by a risk for severe weather. You can expect a repeat of Saturday depending on how stable the atmosphere remains

For the first time in U.S. history, a total solar eclipse that crosses the country from coast to coast will be visible only in America. The rare celestial spectacle in August has been dubbed “The Great American Eclipse.” No one outside the continental U.S. will be able to see the eclipse, which makes landfall on the West Coast near Salem, Ore. and continues diagonally across the country until it hits Columbia, S.C. In addition to being the first total solar eclipse with a trajectory exclusive to the U.S. since the birth of America in 1776, it’s also the first total eclipse of the sun that will be visible from the contiguous U.S. since 1979. The event

Severe and damaging storms made their way across the state this afternoon and evening, flooding the NWS with numerous damage reports. While most of the western section of the state was placed in a slight risk, some parts of the east remained in a marginal risk for thunderstorms. While most of the storm damage reports that we’ve received were also relayed to the National Weather Service, here are a few that we received: In Loretto, Cambria County, there were multiple calls for trees down, as well as a power outage that affected all of the Loretto area. Penelec states that customers will be without power until at least three Sunday afternoon.

There is a slight risk for severe thunderstorms from eastern Ohio into Central Pennsylvania and a marginal risk for thunderstorms from the upper Ohio Valley into western Pennsylvania. Visible satellite imagery suggests ample diabatic heating will spread from Ohio into Pennsylvania as a weak convective cluster north of Pittsburgh shifts eastward and clouds diminish from the west. Although low-level moisture has decreased in the wake of a downstream front along the Atlantic seaboard, surface dew point values in the mid-upper 60s will contribute to MLCAPE of 1000-1500 J/kg across the area. Large-scale NWP and CAM model guidance exhibit considerable agreement indicating storms will develop over eastern Ohio during the early afternoon

Summer storms drenched the region Friday afternoon, bringing heavy rain and high winds that brought down trees, poles and wires and knocked out power for thousands. The first round of storms that pushed through in the afternoon caused some significant damage in parts of the area. The worst may have been in Bellevue. That’s where a massive tree was uprooted along Cliff Avenue. It brought down three utility poles and a bunch power lines across the street on Meade Avenue. No injuries were reported, but power was knocked out to the area. Duquesne Light crews and a tree cutting service were brought in to clean up at the scene. There were power
