And discussion:
QUOTE
...SOUTHERN GREAT LAKES INTO THE NORTHERN MID ATLANTIC STATES...
WEAK SHORT WAVE IMPULSES PROGRESSING THROUGH 20-40 KT WEST
NORTHWESTERLY FLOW...AROUND THE PERIPHERY OF SUBTROPICAL RIDGING
...MAY PROVIDE SUPPORT FOR THE EVOLUTION OF A COUPLE OF ORGANIZED
STORM CLUSTERS. MOISTURE APPEARS LIKELY TO BE SUFFICIENT TO SUPPORT
AT LEAST MODERATELY LARGE MIXED LAYER CAPE ON THE ORDER OF
1000-2000+ J/KG...CONTRIBUTING TO A RISK FOR SEVERE STORMS CAPABLE
OF GENERATING POTENTIALLY DAMAGING WIND GUSTS AND SOME HAIL.

This morning New Rochelle NY(on the coast) heard some loud thunder but just 25 minutes up the line on the CT coast there was nothing. Let the bubble line begin. Lol.

For once, the heaviest part of the T-storm actually stalled over me. Hopefully the beginning of the end of the bubble? laugh.gif

Something interesting for this stormy period is the RUC upgrade... the old RUC was finally replaced by the new RAP (which I assume is also the RR) model. I created a thread on it in the Weather Questions & Info forum. As a result, Twisterdata also extended the RAP graphics to 18 hours as opposed to the old RUC going to 12 hours.

I highly doubt the 5% actually ends up verifying in NJ and further east. The air mass is mostly stable as we're (as usual) stuck in the back door cold front zone.

It's currently around 65 here in Baltimore as we haven't made it out of the marine layer yet.

Starting to see some vertical CU growth along differential heating boundary in VA ahead of s/w in WV. Could be the start to a few severe storms in the Mid Atlantic.

SPC has introduced a 5% SEE TEXT over the region at this time. Should we extend the 4th in this thread or make new thread for Friday's potential?

My mistake... I thought that map was for today... that's what a 2th consecutive day of very little sleep does laugh.gif

The thread should be extended into the 4th, perhaps the 5th as well for southern areas.

All you need to know about Severe Weather Friday for E PA/SE NY/NJ/MD/DC/DE/VA

Link above goes into detail on the current situation and how it impacts the chances for severe weather Friday. This has high bust potential as we could be talking about an iso tor threat/winds/hail or northing come Friday afternoon depending on timing and location of the impulse highlighted.
