Low topped squall line potential 12/14/15

Recommended Posts

Yes this is 6 days out, however, there are strong signals for a rather potent storm system to develop across the upper Mid-west during the weekend in response to a vigorous trough which will amplify across the central portion of the country.  This will allow for some major ridging to develop here in the east later in the weekend and next Monday as well. 

 

The most appealing aspect to the potential system right now is the degree of the dynamics that may be involved.  The GFS is advertising 500mb winds to be in excess of 100 knots approaching New England early next Monday!!!

Once the warm front pushes through the airmass will become unseasonably warm and moist (the GFS is advertising PWAT values as high as 1.3'' next Monday ahead of the cold front!). 

 

Given the potential for such a dynamic system and an abundance of warm/moist air ahead of the cold front, the potential will exist for a forced line of low topped convection to develop along/ahead of the cold front.  Outside of the potential for some very heavy rains, strong/gusty winds would be possible just ahead of a line if one were to develop.

That was cool. I remember seeing the pic.

Nicely written post!

Agreed. Could also be a kind of ribbon-echo squall line sinuously wobbling its way east through a Band of frontal rains - goes through you go to blinding rain and gusty winds for about 3 to 5 minutes.

Don't need a lot of Cape with this kind of thing it's mostly mechanical forcing

If areas can manage to get in the right entrance region of the jet that should help enough with the lower chances of CAPE. Best region looks right now from if you split PA in the center and had a north and a south to about central VA stands in that right entrance region

Had the line come through last night. No lightning that I saw but heavy rains non the less and decent winds as the front passed. Did not for one expect the jet to take on the state that it did with it punching through New England hence the forcing being further north than just CPA. Good call that far out though and if this was summer this would have been a fun one to track.
