I will discuss this in greater detail tomorrow, but I want you to wake up with this knowledge. Hurricane Lee is not going to landfall in the States. I would worry more about that in Nova Scotia. Additionally, this does not mean that US interests on the coast are in the clear. As Lee heads to the north, be wary of rip currents and high surf as the stom heads north.
Please avoid large festivals in rural Nevada today

An anecdote
To give you an idea of the weather scenario we are in right now, I was just on a conference call with people from many parts of the country. One of the attendees from Texas was lamenting the triple digit heat that continues to boil Texans.
Here in Minnesota, I had to wear a light jacket this morning. Fall is coming, people. Eventually.
Update: Brr!

Different vibes than last week
After we were looking forward to a hot couple of weeks for really most of the country, today, we can look at the outlook and see cooler air is on the horizon. Let’s hope that the cool down comes entirely at the hands of an advancing cold front and not Hurricane Lee. (I should note that it is NOT likely to be the result of Lee)

Low pressure will try to deflect the next round of tropical weather
Lee, presently in the North Atlantic, already looking for a trip to the Eastern Seaboard, is a big, scary storm. He’s going to be a Cat 4 before all is said and done, and a Cat 5 is not out of the question. Fortunately, this is the forecast map for Saturday.

That coastal feature should be just enough to shunt Lee away from the coast. Remember that if you are lamenting the weekend rain out East this weekend.
A change in season, thanks to some thunderstorms
We’ve spent some time looking at the temperature trends for September, including some outlooks for the temperature over the next few weeks. Also illustrative, though, is the severe weather outlook. Much cooler weather is coming behind the severe weather.

Additionally, with crops still in the ground, if things get cooler and clearer pretty quick, all that moisture will lead to some foggy mornings, further helping keep temperatures in check. It’s right around the corner.
Not done yet
Even the Duluth WFO is posting things like this about the heat.

Thunderstorms are coming to the area Tuesday night. Expect an abrupt end to the heat wave.
Hurricane Idalia will landfall tomorrow
Idalia looks like she will make landfall tomorrow at about the spot that was expected before it even had a name. Initial model guidance wasn’t as aggressive on the storm’s intensification as the NHC was, so credit as always to the meteorologists, but here is the good news:
The Big Bend are of Florida is fairly sparsely populated. Storm surge, thanks to the geography of the region, will be quite high for Cedar Key north and westward, but there aren’t a lot of beachfront communities in the area. Not to say there aren’t any, but the most costly part of this storm will not be the surge, even though it will be impressive.
Instead, my biggest concern is the flash flooding that may come to places like Live Oak, Valdosta and Wenatchee. Sporadic tornadoes are also a big concern, as they usually are with landfalling hurricanes.
Idalia is a healthy storm, and will be memorable for those it impacts. The only reason this storm isn’t more fearsome is because it found the part of the Florida Coast that hasn’t been fully developed.
I see you, Idalia

Hurricane Franklin holding up traffic

Franklin is a big beautiful storm, with a well developed eye that is mercifully spinning well away from most major interests, save for the air and sea interests of the North Atlantic. He is not getting much attention, because he isn’t going to make landfall anywhere, and will merely work to reroute aircraft and ships.
All that said, he is causing a trough in the mid-Atlantic to slow down, and the rain showers in the Virginias over the weekend dumped enough rain to cause some flash flooding over both states. As Franklin keeps moving, ultimately so will these showers. With luck, Idalia will also steer clear of the region.
