Areas affected...Northern Mid-Atlantic into southern New England

Concerning...Severe potential...Watch unlikely

Valid 181501Z - 181630Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated wind damage is possible with strong to marginally
severe storms late this morning. A watch is not expected.

DISCUSSION...A small linear cluster of storms has recently organized
in northern New Jersey and adjacent northeast Pennsylvania. Storm
cores have shown modest deepening on 7 km MRMS CAPPI over the last
30 minutes. The observed OKX sounding had poor mid-level lapse rates
(5.3 C/km) but 45 kt of effective shear. Downstream of this current
activity, cloud cover and smoke have hindered surface heating.
Low-level lapse rates are not expected to be overly steep. While
isolated wind damage is possible late this morning, the severe
threat should remain marginal on account of very limited buoyancy. A
watch is not expected.
