Tuesday/Wednesday Storm


CT Rain

Recommended Posts

Some breaks of sunshine working into Delmarva/S NJ and temps are up to 77-78...With dews around 70, 77-79 degrees should be sufficient for 800-1000j/kg sb CAPE..starting to see that show up over Cape May on latest mesoanalysis..That should be enough for some interesting weather here given the kinematics in place

The breaks are definitely happening like what was being signaled on the NAM last night. If other clusters besides NC can appear to become threatening, I wouldn't be shocked at a moderate risk issuance this afternoon for the Mid Atlantic.

Agreed, and 12z nam continues that theme...looks really impressive in central/s NJ centered around 21z this aftn.

The increased rainfall in PA-MD is from a vort max ahead of the main trough (positive differential CVA), theta-e/moisture advection and general low-mid level enhancement from wind/waa. I am not exactly sure how this will play into the building severe threat (will it matter or not).

It is certainly giving the impression that eastern most areas of the Mid Atlantic have the highest threat.

my davis on ground level tripod gusted to 31 mph in the last hour short beach branford..some people already out there trying to tie up their boats as they bob up and down on the waves last minute.not saying it will be like irene in anyway,but its starting the same way leaves all over the porch and some twigs scattered about.it will be interesting to see what its like later today.

wind is up all the sudden here...35mph?

-

funny on the comment about people tying up boats-how many tropical threats have we had over the years where the winds have in reality delivered less than today after a whole lot of hype?

Tornado watch for MD down to NC now.

Yep i posted in the banter thread, we had two gusts that were impressive down here, which coincided with a brief shower. Heading down to take some pics this afternoon.

It'll be interesting to see what happens of this... wind-wise that is. Typically you need some sort of destablizing lapse rates in the boundary layer for obvious reasons. CAA is the best way to do this, but getting deeper into a barotropic air mass where the sounding tends to be right at 9.8 per, can be very interesting provided the actual PGF is sufficiently large. Eikmen frictional effects still need to be overcome in the interior in those barotropic cases, but it is easier to do if 9.8 per, then if there is any inversion at all. Get up into elevations and you can see why some of these 3.5 hundred foot hill tops like the Monadnocks appear denuded of trees (ha).

If there is any baroclinic tendency to the pre-frontal environment (i.e., a warm frontal slope) then you are not likely to verified as much wind in interior sections. I have seen as many as 12 isobars in a lead occlusion district of a frontal passage, in the past, verify 25kt winds in the interior. Meanwhile, it raging just above or on the marine contaminated coastal plain.

Obviously a ribbon echo squall and/or lead convective elements in general could overcome, but outside those microscalar events, in terms of getting a sustained wider-spread wind event, they seem to underperform over the longer haul for much of these details.
