Chilly tonight, more smokey sunshine for Wednesday

Forecast

Watching Sally's path for late this week...

OVERNIGHT: Clear & Cool. Lo 46. Winds calm.

WEDNESDAY: Hazy Sunshine. Hi 77.

THURSDAY: Increasing Clouds. Hi 80.

High pressure continues to provide comfortable, fall-like air in Pennsylvania. With clear skies and calming winds tonight, temperatures will dip into the 40s again, likely a few degrees cooler than last night! Wednesday will be warmer than today, but still below average thanks in part to the continued smoke plume overhead. Sunshine may appear “filtered” or “hazy”. This is due to a smoke layer in the atmosphere that has drifted east from the massive wildfires in California. So although it will be sunny, the brilliant blue skies that would normally appear during a pattern like this may be smoky instead.

A weak cold front will drop in from the Great Lakes on Thursday making for increasing clouds. That front will help to steer what’s left of Hurricane Sally into the Mid-Atlantic. Moisture from Sally could move northward by Friday and Saturday, drawing some clouds into our region. Rainfall from the tropical system looks to remain south and another ridge of high pressure should build in for more spectacular weather by the upcoming weekend! Some long-range models do bring a few showers just south of PA by late Friday/early Saturday. While this bears watching, it still appears most of Sally’s moisture will stay south. While the tropics remain active, our weather looks fairly quiet. Spend some time outdoors this week and enjoy the cool, pleasant nights!

Tropical Update: Sally is grinding to a halt as it nears the northern Gulf coast. It has weakened to a Category 1 hurricane but it will still pack massive amounts of rain and life-threatening storm surge as it takes its time making landfall Wednesday morning. Rainfall amounts of 10-20″ are likely along the Alabama and Florida panhandle coastline which will result in historic flooding. The storm should move north and pull away from these states by Thursday, affecting Georgia and the Carolinas with heavy rain through Friday.

In addition to Sally, we are monitoring three other tropical systems in the Atlantic: Paulette, Teddy, and Vicky. Vicky is expected to fizzle over the next few days and Paulette will race into the northern Atlantic. Teddy is expected to strengthen into a major hurricane, but any threat to land also appears minimal at this point. Let’s hope this all holds while the U.S. deals with Sally this week.
