What is this? Scattered TS from Mexico to New York?

[HouTXmetro]

Why is there scattered TS all the way from Mexico extending throughout Texas, the Midwest, the Southeast and into New England? What kind of weather feature are we dealing with here? Is there a strong trough in place that might influence Emily.

Who else sees this?

Bump

Another thing to note is that there are some healthy cells building around Brownsville. Would not be good if the rain saturates the area before a potential landfall. Comments about the synoptic situation occuring across the areas I mentioned would be greatly appreciated.

I don't know enough about weather to say why, but we've had cloudy, rainy, stormy weather since the depression from Dennis arrived here many, many days ago. I don't know if he never moved on or it's from something else. Thunder has been rumbling for the past hour.

It appears that the same system is causing daily scattered storms here also. The line of scattered storms extend from just south of the TX/MX border all the way into New York. Is it a front, trough? I would really like to know the implications if any this system will have on Emily.

Normally a front would steer a hurricane to the North a little but to early to tell if it will stay in place long enough.

Maybe that is the Dennis remnants in Texas causing the instability?

Well I would argue whatever it is, it's getting stronger. Unlike yesterday, the TS are extending well into the Mexican border.

How come the same showers (motion of the storms) extend well up into the east coast?

widespread leftover moisture and troughiness from Dennis, combined with major July heat = daytime thunderstorms. There is just enough of a trough left over from Dennis to allow for this. I'd imagine it will go away when the ridge begins to rebuild in these areas acting to cap the atmosphere next week.

Thanks, great explanation.

this is the trof that NHC is now talking about...from dennis as well....and yeah, i see that the storms are stronger and into the gulf...we will have to see if this will impact emily...i think maybe nhc is really starting to pay attention to this

Hey Purdue,

Good call. I completely agree. It looks like the NAO is progged to hit its lowest level in a long time.

I could be wrong, but I think this may be due to the remnants of Dennis forming a deep low off the maritimes and hanging out there for a while. The last time it crossed down to negative was around the time Arlene formed. It will be interesting to see how the tropics react to the NAO since we've been positive for almost a month.

We have been having morning thunderstorms and afternoon thunderstorms here. I just thought it was moisture coming up from the Gulf and mixing in with the air inland and causing storms. I don't know!

[Brent]

It's Dennis moisture. Been like this all week here...

[coriolis]

....and it's miserable, sticky, and yucky. It's been raining on and off all day. The thuderstorms don't even clear things out. They just make it worse. Staying inside with the A/C. I'm cringing just thinking about the electric bill.

[coriolis]

79 degrees, dewpoint 75 degrees here

[WaryEye]

84 degrees, Dewpoint 74 here. There is no other way to describe how it feels outside other than : Disgusting. You don't even feel like you are breathing fresh air. Here too we have had thunderstorms on and off constantly for days now. I am sick of it. Need to cut the grass!!! The grass can't dry long enough to cut it. LOL Looks like the air will begin to get drier by Wednesday.

[wxwatcher91]

yep, a lot of thunderstorm activity out there...
spc has the entire US in an outlook for non-severe storms 'cept Kansas, and also the West Coast...

here's a mpa of the action...

[JenyEliza]

Temp 87.8, dewpoint 74, and thunder-boomers rolling in.

Just in time to continue dampening my already very damp home and crawl space (where I have fans going right now to dry it out).

We got 5" of rain from Cindy. Then Dennis dropped another 11.67" of rain just three/four days later and it's been rainy every day since.

We need sunny, 90 and NO RAIN for about 3 or 4 weeks to get everything dried out and the mold in the crawl space under control.

Running the AC to keep the living area dry (but the house smells moldy because of the moist moldy crawl space the heating/air ducts are in).

Rain, rain go away. Come again another day.
