.AVIATION UPDATE (14/06Z ISSUANCE)…LOW CIG AND VSBY CONDITIONS CONTINUE. GOES IMAGER 11-3.9 AND MODIS POLAR ORBITER CONTINUE TO INDICATE A LOW STRATUS DECK WITH LOW VISIBILITY IN A LAYER WHOSE EDGE OVERLAYS A LINE FROM NEAR FOLEY TO BAY MINETTE AND ON UP TO CAMDEN. POINTS WEST OF SAID LINE ARE PRETTY WELL SOCKED IN AND PRETTY CLEAR ELSEWHERE. HAVE THEREFORE KEPT REDUCED PREVAILING GROUP TO A QUARTER MILE AND VV001 FOR BFM AND MOB.

A comparison of AWIPS images of the 1-km resolution MODIS vs the corresponding 4-km resolution GOES-13 fog/stratus product (above) demonstrated the advantage of using higher spatial resolution data to more accurately locate the eastern edge of the fog.
