9:11AM. A lot more mental energy is spent on the Atlantic side of the tropics, and for good reason. The Pacific is generally more active, but after storms get going, there is just less out there to impact. Take a look at Hurricane Narda, which will do the typical tropical poleward curl and really only impact some fish. And that’s a fairly typical eastern Pacific lifecycle.

4:34PM. And back to the mainland. TS Nine has now developed near Cuba, as expected. It stands a pretty good chance at this point of landfalling between Charleston and Myrtle Beach as Tropical Storm Imelda, if the track remains approximately the same. The good news is that it will probably not be a hurricane when it does so. It does look to lumber through the region though, and heavy rain is going to be a problem in the Carolinas this weekend.

9:48PM. All clear in Texas tonight.

11:11PM Make a wish! With eyes turning to the Bahamas for a little bit of tropical development, we can all feel better about ignoring the local weathermen. This late September pattern is warm, and hasn’t really featured a lot of severe weather. The SPC outlook only has anything greater than general storms as a marginal outlook associated with the monsoon along the Arizona/New Mexico border.

4:37: As it was when I wrote about the hurricane season earlier, it is the Atlantic that is active, rather than the Caribbean or the Gulf, and as I noted, the Atlantic itself is plenty hospitable for tropical development. We now have Humberto, and more pressing, an area that stands to sustain more development as it tracks through the Bahamas later this week.

8:36PM Here are the forecast tracks of a still unnamed storm. It will pass over the Dominican Republic overnight tonight, which will certainly slow down any real development. As it get into the Bahamas we are probably then looking at a Tropical Storm (Imelda), which then looks like a Cat 1 hurricane along the Outer Banks. Maybe. Stay tuned.

11:05PM: The Mid Atlantic track of our tropical season has made for a very dull time in the southeast. Without clouds, temperatures are a degree or two warmer than normal, to go along with dry conditions. Fortunately, perhaps, there is rain coming for parts of north Florida and south Georgia and Alabama on Friday. That might be nice.

2:07PM: A sure sign of high pressure in the middle of the country is an inversion. This means temperatures don’t continuously get colder as you go up, which traps air nearer the surface, and can make for an icky atmosphere. Such is the case in St. Louis, where there are air quality alerts today.

10:45PM: The pattern isn’t particularly strong, but that means what is there is just kind of hanging out. A weak area of low pressure centered over the Nebraska/South Dakota border is going to kick up showers over the central Plains, and it will keep on accumulating. Impressive in it’s persistence.

9:35AM: In the absence of any major synoptic scale features over the central CONUS (the big feature is a stalled boundary over the Florida Peninsula), the real weather maker is the general topography of the US. There area already some showers over the Rockies, and westerly flow across the mountains will lead to a it of localized low pressure in the lee. Without much upper level support, it will be like my Uncle Jack and never really make much of itself.

8:16PM: I should note that the area of low pressure that I mentioned in today’s earlier post is also draping a cold front across the Florida that is in essence single handedly scrubbing any drought concerns the area has. It’s also the only thing even close to interesting in the hurricane zones of the CONUS. I ain’t mad.

9:59PM: I told you cold snaps don’t last!

6:47PM: It’s a pretty quiet stretch out west, even in the Rockies, where we might reasonably expect some afternoon thunderstorm activity this time of year. Instead, we are seeing the Rockies work as a pretty formidable dry line. As the jet shifts back up to the north a little bit, don’t be surprised to see some activity return to the mountains. That could happen as soon as Wednesday, and would also coincide with the Great Lakes finally drying out. (Not the lakes, but the towns surrounding them).

1130PM: There is a pretty gnarly looking cluster of thunderstorms, that, if nothing else, is producing a heck of a lot of lightning in the Clovis, New Mexico area. It would be jarring for a lot of places, but this qualifies as run of the mill for this time of year in this part of the country. Do they sleep along the Texas/New Mexico border?

4:12PM: The images our of southeast Wisconsin have been something else. Flash flooding has come to the region thanks to slow moving, high precipitation storms, moving through high population areas. That same set up is still stretched across the south side of Lake Michigan. There are flash flood watches and warnings over Chicago, particularly on the south side of town.

8:03PM: It’s been a quite humid year, if you haven’t been around…. or if you live in the Great Basin. Nevada, most specifically, has been quite a bit less humid than it is typically this summer.
