May 2018 Observations & Discussions

A distinct low level center of circulation can be seen over land now.  (within the yellow circle).  NHC has very high probability for trop development within the next 2-5days, however, only slow development is likely once the LLC moves out over open waters of the GOM over the next 2days.   There is currently very strong wind shear(blue arrows) west to east to the north of the system that will likely inhibit any rapid intensification.  Unless the shear drops off significantly anything beyond a TD or weak TS is not likely. Even that may not develop if the wind shear does not diminish some.  Notice the higher cloud tops are well east of the LLC as a result of the shear(black circle).

Another look at the current wind shear

Give it time, Scott. It has to couple and slide beneath the upper-level low. Once it does that it will begin to intensify pretty steadily I think. I think a high-end TS or low-end Cat-1 will be achievable here. Right now it is still out ahead of the mid-level feature which is why it's sheared right now - essentially it's developing like a typical mid-latitude cyclone (same processes involved right now). Once it gets beneath the mid- and upper-level low(s), the shear will back off significantly, and the low-level center can then begin the W.I.S.H.E. feedback and warm/intensify it from the bottom up.

Trust me I understand what your saying.  The LLC is still over land; however, looking at the shear forecasts to the systems N over the next 48-72 hrs combined with the dry air that remains to the west of the system, I am highly skeptical that we ever achieve high end TS/Cat one status.  If we do its very short lived and likely never becomes much of an issue for land with the exception of a very small area around the center as it is likely very short lived unless the center stalls just off the Gulf coast.  There are some differences with the upper level trough over the GOM now between the GFS and Euro regarding its orientation over the next 72hrs.  If it remains neutral; certainly positive like it is now, then shear will prevent any real good organization and coupling of the mid/upper level centers with the LLC; however if it tilts neg then maybe.  Well see just how organized this system can really get, but for now I am skeptical.  I think IF we see true tropical characteristics and organization beyond a weak TS/Depression status we need to wait until it reaches at least 25-26N lat to do so.  Well see.

Looks like several LLC this morning on visible sat imagery

They named it this morning. We have "Sub Tropical Storm" Alberto.

Personally I think thats ridiculous and a bit premature, because clearly there is a LLC well south of where they have the center positioned meaning that there are at least two LLCs, and it is still highly disorganized.  

wow hit 90* ....i love the sun...but can I ask how many days till winter????

88 degrees with sunny skies. Tomorrow I am heading out to the beach even though the water temperature is still cold but I am jumping in.

I dont know?? Frank must have done something to it because I didnt.

Perfect day to be at the beach even though the water was cold. Now we have lots of lightning and thunder early high of 90 degrees

Catastrophic flash flooding again in Ellicott City, MD and around Baltomore area in general.

Picked a hell of a day to visit Ellicott City, MD. This is real.

saw that yesterday absolutely horrifying..feel so bad..they just recovered from the last flash flood

we had 2.5 inches of rain yesterday...

Just a few more days of May left. Time is flyin'

June looks like it wants to get off to a below normal start. A lot of cut-off low's showing up in the long range under an NAO block.

Weather in general in our area has been uneventful for my liking. Looks like a rainy weekend ahead. Why have our weekends been timed with crap weather??

Happy belated Birthday you old timer!!!! Hahaha hope your day was well spent!! Your post is music to my ears regarding the extended; I'm done with this heat, give me winter again!!! Frank, you're the man to get that accomplished......I beg of you, please strike a deal with Mother Nature lol or as you also said, at least make it more interesting to pass the time lmao

Already miss the cold, eh?

Here is the cut-off low this weekend:

'

Then next week the trough offshore links with another dropping down from Canada:



And mid-June the trough is still there



Obviously below normal in June is not "cold" but it will not be the scorching heat nor humid air mass we've seen. The west is going to BAKE.
