AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MARQUETTE MI
1105 AM EDT SUN OCT 8 2000

FCST CONCERNS WILL BE ENDING LINGERING -SHSN/-SHRN AND SKY 
CONDITIONS.

LAST OF THE LAKE EFFECT SN/RN IN NCNTRL UPPER MI WINDING DOWN 
QUICKLY NOW. SNOWFALL WAS A RECORD BREAKER HERE AT THE OFFICE. THE 
STORM TOTAL OF 11.4 INCHES IS THE GREATEST SNOWFALL FOR SO EARLY IN 
THE SEASON.

PER SAT IMAGERY...DRIER LOW-LEVEL AIR IS MOVING SE INTO FA AS SHOWN 
BY BACK EDGE OF CLOUDS MAKING STEADY SE PROGRESS. 12Z UPPER AIR PLOT 
AND 12Z RUC SHOW 850MB THERMAL TROF (-8C) NOW ACROSS UPPER MI WITH 
NW FLOW WAA TAKING HOLD NOW. 850MB TEMPS PROGGED TO RISE TO AROUND 
-4C BY 21Z. FCST SOUNDINGS SHOW INVERSION FALLING TO ABOUT 4KFT THIS 
AFTN FROM THE CURRENT ROUGHLY 6-8KFT PER KMQT 88D VWP. CYPL 
SOUNDINGS FROM 00Z AND 12Z SHOWED INVERSION CRASHED FROM 4KFT TO 
1.5KFT ALONG WITH PRONOUNCED LOW-LEVEL DRYING (DWPT DEPRESSIONS OF 
20-30C IN THE 900-600MB LAYER). IN COMBINATION WITH FLOW BECOMING 
INCREASINGLY ANTICYCLONIC...EXPECT REMAINING -SHSN/-SHRN TO END 
QUICKLY THIS AFTN. IN FACT...WILL JUST MENTION SPRINKLES/FLURRIES 
ENDING FOR ALGER/LUCE...NO PRECIP MENTIONED ELSEWHERE.

ALTHOUGH LAKE EFFECT CLOUDS WILL BE BREAKING UP...SCT-BKN AREA OF 
WAA CLOUDINESS ALREADY SPREADING S FROM ONTARIO. SO NOT EXPECTING 
SIGNIFICANT CLEARING THIS AFTN. GOING FCST HAS A GOOD HANDLE ON 
TEMPS. WILL MAKE JUST A FEW MINOR CHANGEiS.

.MQT...NONE.
