Recon reports aren't usually useful to upgrade or downgrade the storm. They are more of a position report for the aircraft and crew.
They normally fly a fixed pattern, and their reported winds will vary greatly. Even over 5 miles!
The new NHC Advisory should be out soon and the will let everyone know what Arlene is doing. At least what they and the computers think she is doing.

I was looking at some of the High Density observations from NOAA earlier and the wind speeds would vary as much as 15 kts over 6 miles. Windspeed woud drop off a few kts and then a few more miles it would either increase about 15 kts or continue to drop.
If you do a search on Hurricane Research Division, they have some wonderful graphics from past Hurricanes. You can get an idea of what they are gathering as they fly. It will give you a different dimension to look at.
