Good morning to everyone!

It appears there may be a decent chance for some showers, especially across the northeast and eastern portions of the forecast area. Here's a look at where the Atlanta NWS thinks the best chances are.

not much going on across the southeast right now. The zonal flow is taking all the lows to our north at the moment and that means the really active weather stays up there as well. The morning map (300 mb heights, wind and surface dewpoints) shows that west to east flow that is in place at the moment. We are sitting just to the east of a weak trough (the dip in the purple lines) and you can see the drier (and cooler) air over much of the country. Once again, we sit right on the edge. morn-08.thumb.jpg.c494941fd5ee5d84b7023fedb3d9a6f5.jpg

 

There will be a major snowstorm brewing for the northern Rockies and spilling into the upper plains later in the week, and temperatures in some areas will be running 20-40 degrees below normal for this time of the year. Take a look at these temperature anomalies.

The colder it gets up north, the colder it will eventually get here. I hope they get 50 feet of snow and zero degrees. 🙂 Lay down the carpet for the emperor of the north. 🙂 And speaking of the white carpet, these are the potential snow amounts from this late week storm.

I have no doubt that we will see the effects of Hagibis in 7-10 days, and it's possible that we'll see some dramatic changes in the weather across the US. Big storms, and this is a really strong storm, interact with the jetstream once they reach higher latitudes, and that interaction causes large amplifications in the speed and location that it travels. Can't wait to see the impacts. 
That is a 236 mph jet. 

 

So I'll be watching for the next excitement on the horizon. I hope everyone has a great day!

There is no season when such pleasant and sunny spots may be lighted upon, and produce so pleasant an effect on the feelings, as now in October.

Will Hagibis help push down colder air to us?

The thoughts are is that it will cause a deep trough to form over the eastern US, and if that happens, yes.
