Helping Business Weather the Storm

National Weather Summary for Friday, October 30, 2015

by WeatherOps, on Oct 30, 2015 4:50:40 AM

Scattered severe thunderstorms are possible Friday across Central and Southern Texas. Excessive rainfall is likely from Central Oklahoma across much of Texas, as well as the Pacific Northwest.

A strong upper level low is expected to dig into the Southern High Plains on Friday, allowing for a surface low to develop over West Texas. This will allow for warm, moist air to flow northward out of the Gulf of Mexico into the region. Thunderstorms are expected to develop over central and southern Texas. Given the unstable air mass that will be in place, as well as the strong winds aloft, some thunderstorms will be capable of becoming strong with the primary hazards being damaging winds and isolated tornadoes.

In addition to the severe weather threat, deep moisture in place will allow for heavy rainfall. Widespread rainfall accumulations of 1-2 inches with locally higher amounts in excess of 5 inches will be possible. Given the recent heavy rain across this area, additional rainfall may lead to flooding.

A strong low over the northwest Pacific Ocean will lead to enhanced westerly, onshore flow across the Pacific Northwest. Combined with orographic lift along the coastal mountain ranges and the Cascades, heavy rainfall is expected to develop. Widespread rainfall accumulations of 1-3 inches are expected with locally higher amounts in excess of 5 inches possible in some locations.
