irishbri74 Posted April 13, 2020 Author Report Share Posted April 13, 2020 Inversion holding strong so far. Thought we had a chance to be a little windier with these am showers. Haven’t seen anything above 40mph yet. Let’s see what later brings as the sun comes up, maybe we clear out for a few hours and mix out. 1 Quote Link to comment Share on other sites More sharing options...

tombo82685 Posted April 13, 2020 Report Share Posted April 13, 2020 Said this earlier but be careful of posting wind maps off models they always verify to high. For instance hrrr had 50+ mph wind gusts already. Philly hasn't even got past 40 yet. Quote Link to comment Share on other sites More sharing options...

Looks like highest low-level winds are overhead now with 60-70 knots of 0-3km shear. Quote Link to comment Share on other sites More sharing options...

Sounding is to wet to adequately transport it down. If we get some sun and dry out later, then chances of bigger wind increase or any svr storm.

Isopleths are bulk shear surface to 500mb. Shear is weakening as instability increases, good thing they were not aligned. Quote Link to comment Share on other sites More sharing options...

irishbri74 Posted April 13, 2020 Author Report Share Posted April 13, 2020 Northern VA to PA area late morning into early afternoon... There will be a window of opportunity for surface-based storm development later this morning through early afternoon from VA into MD/DE/NJ and PA with the synoptic cold front. Boundary-layer dewpoints in the upper 50s to lower 60s north of the pre-frontal squall line farther south, and some cloud breaks later this morning, should allow at least weak surface-based buoyancy to develop. Vertical shear will be strong and a broken band of storms, capable of producing damaging winds and a couple of tornadoes, is expected to form and persist from roughly 16-21z (the precursor of which is the convection now near the OH/WV/KY border). ..Thompson/Kerr.. 04/13/2020 Latest from the spc Quote Link to comment Share on other sites More sharing options...

If that happens, could be trouble for better chances of mixing down and weakening inversion 1 Quote Link to comment Share on other sites More sharing options...
