Reason for the small overcast area is that the station only have full influence in a 2 mile radius.4 nearby stations at the same time:KSUS 050454Z 11004KT 10SM BKN110 05/M04 A3033 RMK AO2 SLP275 T00501044KALN 050525Z AUTO 11005KT 10SM BKN110 04/M04 A3033 RMK AO2KSET 050354Z AUTO 11006KT 10SM CLR 03/M04 A3034 RMK AO2 SLP276 T00331044KCPS 050453Z AUTO 13005KT 10SM FEW060 BKN120 04/M04 A3036 RMK AO2 SLP283 T00441039 TSNOAs you can se none of those have overcast so thats why you get a small patch right above the airport.

Interesting. Thanks, JT, for the explanation.Marty
