Friday Discussion : Debby Brings Severe Threat

The remnants of Tropical Storm Debby are now pushing into the Mid Atlantic and Hudson Valley.  Being on the east side of this system will put the Hudson Valley in the area of concern for some isolated severe weather on Friday. With a weakening tropical system, there will be a good deal of atmospheric shear.  That combined with the convective development on the eastern side of the storm rotation will give rise to the threat of some severe T-Storms, strong gusty winds… and possibly a tornado or two. If we look at the current radar as of 11am, you’ll see the big batch of rain to the west of the Hudson Valley… Current Radar Loop : 11am Friday If you look at the large area of rain over central PA and central NY… then look to the east of there, you can see “Newburgh” on the map.  Notice how the convective rain showers and embedded downpours just seem to develop right over top of us?  That’s the atmospheric lift leading to the convective development of showers and T-Storms.  All powered by the remnants of Tropical Storm Debby.  This is what the Hudson Valley will have to contend with for the day on Friday into Friday night. Maximum Wind Gusts : Friday – Friday Night In addition to the threat for scattered showers and T-Storms Friday afternoon and evening, the winds on the east side of the system will be howling.  Gusts between 30 and 50mph are likely Friday afternoon and evening.  So make sure any loose objects are secure.  The peak time for these gusts will be between 11am and 9pm on Friday.  Winds should diminish considerably before midnight. A blustery and busy day for the region.  More updates to follow…
