EVENT...HEAVY SNOW EVENT
.
SATELLITE ANALYSIS AND TRENDS...A DEEPENING SHORT-WAVE LOW CONTINUES TO
PROGRESS EASTWARD THRU NORTHERN INDIANA WITH A CLASSIC COMMA-HEAD CLOUD
STRUCTURE.  EMBEDDED COOLING CLOUD TOPS JUST NORTH OF THE TRACK...THRU
SOUTHERN LOWER MICHIGAN...ALSO SIGNIFY PROBABLE INCREASING SNOW RATES.
CURRENT ESTIMATES SUGGEST RATES UP TO 2-3" PER HOUR FROM N.W. INDIANA
INTO SOUTHWEST MICHIGAN.  BUT EXPANDING AND COOLING CLOUDS ALONG THE
STATE BORDER SUGGEST THESE RATES ARE POSED TO INCREASE FOR THE NEXT
COUPLE OF HOURS AS THE TRACK OF HEAVIEST SNOW RATES MOVES ENEWRD THRU
SOUTHERN MICHIGAN.  THE SPEED OF MOVEMENT OF THE UPWIND EDGE OF THE
CLOUD MASS WOULD SUGGEST SEVERAL HOURS OF THE MAX RATES ALONG THIS PATH
SO POSSIBLE MAX TOTALS TO 6-9" POSSIBLE BUT WITH SURFACE TEMPERATURES
AROUND FREEZING SOME SETTLING MAY OCCUR.  COLDER AIR ENTRAINMENT JUST
NORTH OF HERE...THRU SOUTH-CENTRAL MICHIGAN MAY ALLOW SLIGHTLY HIGHER
AMOUNTS THRU THIS REGION.  WILL CONTINUE TO MONITOR.
