Thursday, 9:30 a.m.
In the video, we look at prospects for the coming weekend and early next week in the Northeast and Great Lakes. Also, we visit the latest version of the forecast for 2 p.m. on Oct. 10. You may recall that we looked at this date on the GFS model early this week and saw what appeared to be a heavy wet snowfall underway in central and northern Pennsylvania. If you don't recall seeing that map, let me say this: we looked at this date (Oct. 10) on the GFS model early this week and saw what appeared to be a heavy wet snowfall underway in central and northern Pennsylvania.
One feature that will affect the weekend weather will be a strengthening trough aloft that heads for the eastern Great Lakes. It will trigger showers, perhaps some thunderstorms and even waterspouts over the Great Lakes as it moves through. This prog map shows where it could be early Sunday morning:
If the ridge was the only thing involved, it would just be sunny hot and humid day after day. As it is though, there are various minor disturbances rippling through the ridge. One such disturbance has allowed cooler air to spread down the coast.
This map shows where the storms were at 10:18 AM ET. That cluster of storms may hold together, but in response to daytime heating, new ones can pop up at other places this afternoon.
On this map, two such features (short waves) stand out today. The one in Ohio caused some thunderstorms in Michigan and Indiana yesterday. The other short wave is causing thunderstorms this morning from western Wisconsin to northern Missouri.
Scotty the Dog will be four-months-old in four days. On walks during hot weather, he is quick to seek out shady spots. He has yet to experience any cold weather, but he looks like he will be ready when it arrives (not any time soon!).
Erika's heavy rainfall separated into two areas yesterday. This is the Morehead City, North Carolina, radar, showing an area of heavy rain and thunderstorms that dumped more 4 inches of rain on parts of the coastal Carolinas this morning.
Tropical Storm Erika could eventually affect Florida and other sections of the Gulf Coast or Southeast, but for now it poses no threat for the Northeast. This map shows the storm as of early this morning.
