Tropical Storm KYLE (Text)

Tropical Storm Kyle Discussion Number   3

500 AM AST Sat Aug 15 2020
The low-level center of Kyle continues to be exposed to the west of 
the deep convection, as strong westerly shear prevails. Although 
the satellite appearance is not that impressive, the circulation is 
well intact as indicated by a recent ASCAT overpass that reveals 
that the initial intensity remains 40 kt.
Kyle is currently moving east-northeast at 18 kt, and away from the 
U.S. coast. This general motion is expected to continue for the 
next couple of days, with a turn to the east and an increase in 
forward speed thereafter as the system remains embedded in the 
mid-latitude westerlies. The official forecast track is little 
changed from the previous one, and is near the tightly clustered 
track guidance. 
Only slight strengthening is expected over the next 24 h as the 
cyclone crosses the warm Gulf Stream waters and interacts with an 
upper-level trough, while battling increasing westerly shear. The 
forecast track takes Kyle over much cooler waters starting in about 
24 h, and by that time, the system is expected to begin interacting 
with a frontal boundary to its north. This should initiate an 
extratropical transition that is expected to be complete by 36 h. It 
should be noted that both the FSU GFS-based phase space forecast 
and SHIPS guidance suggest that this transition could be completed 
sooner than indicated. After transition, the extratropical system 
should slowly decay until it is absorbed by a larger extratropical 
low in a little more than 3 days.
