A comparison of GOES-12 and GOES-13 visible images (above) showed a long lake-effect cloud band that was oriented generally north-to-south across Lake Michigan on 20 January 2009. Convergence of surface winds was helping to sustain the cloud band over the lake, which... Read More
AWIPS images of the GOES-13 fog/stratus product (above) showed a patch of stratus cloud that developed quickly as it moved northeastward across southern Wisconsin during the pre-dawn hours on 06 January 2009. In advance of this cloud feature, air temperatures were dropping off as clear skies and light winds were promoting strong... Read More
The GOES-12 satellite (which had experienced a thruster anomaly back on 14 December 2008) was re-activated on the morning of 05 January 2009 (beginning at 15:15 UTC). A comparison of GOES-13 and GOES-12 visible images (above) centered on Tampa, Florida showed that the GOES-12 image... Read More
AWIPS images of the GOES-13 fog/stratus product (above) showed a plume of advection fog curling northwestward across southern Oklahoma on 02 January 2009. A relatively moist low-level air mass with dew points in the 40s F was flowing from northeastern Texas into southeastern Oklahoma (where radiational cooling was allowing surface air temperatures...
