Finally another update!
Time has really been flying by lately. We have had such an interesting pattern here across the NE United States. Our weather has been influenced by a deep trof for weeks. 500mb temperatures have been chilly since my last posting in May! (June temps actually averaged above normal for most Climo stations in Connecticut!)
I had to post an awesome example of PVA vs NVA. I was taught in Meteorology school back in The United States Marine Corps to make vorticity your friend. Today was a great example of how strong 500mb uvv's can combine with moisture and surface heating to make some big CBs that eventually led to severe thunderstorms.
Here is the modeled vort max for 18 z:
Here is a visible image shortly after the above analysis. Notice the convective clouds with TRW and hail to the east in the PVA area.
West of the axis, skies are sunny to mostly sunny associated with downward motion and NVA. Cool stuff! -Gil
