OCTOBER 2014 TEMPERATURES AVERAGED OUT NEAR TO SLIGHTLY BELOW NORMAL
WITH PRECIPITATION NEAR TO MODERATELY ABOVE NORMAL. BUT AS IS
TYPICAL OF A MICHIGAN FALL... IT WAS NOT WITHOUT ITS TEMPERATURE
SWINGS AND PRECIPITATION SPELLS.

MANY LOCATIONS IN SOUTHWEST LOWER MICHIGAN RECEIVED OVER HALF OF THE
MONTH/S PRECIPITATION IN THE FIRST FOUR DAYS. A NUMBER OF SITES
COLLECTED OVER TWO INCHES OF RAIN IN THIS TWO DAY PERIOD AS MOISTURE
FROM THE GULF OF MEXICO WAS DRAWN NORTH. THIS WAS FOLLOWED BY COLD
AIR ON OCTOBER 4 WHICH PRODUCED SCATTERED SHOWERS AND A MIX OF RAIN
AND SMALL HAIL.

THE SECOND WEEK OF OCTOBER INCLUDED A MOSTLY SUNNY STRETCH WITH
SOMEWHAT BELOW NORMAL TEMPERATURES. THIS WAS FOLLOWED BY CLOUDS AND
OCCASIONAL RAIN FROM OCTOBER 13TH THROUGH THE 21ST. CLOUDS HELD THE
LOW TEMPERATURES WELL ABOVE NORMAL UNTIL CLEARING ALLOWED FOR THE
FIRST WIDESPREAD FREEZE IN SOUTHWEST LOWER MICHIGAN ON OCTOBER 19.

A DRY PERIOD FROM OCTOBER 22 THROUGH 27 FEATURED GRADUALLY WARMING
TEMPERATURES. THE WARMEST HIGH TEMPERATURES OF THE MONTH OCCURRED ON
THE 27TH. HIGHS WERE IN THE MID 70S... AND MUSKEGON SET A RECORD
WITH 75 DEGREES.

OCTOBER ENDED WITH A TASTE OF WINTER AS A POTENT UPPER LEVEL SYSTEM
FROM MANITOBA DOVE THROUGH THE GREAT LAKES ON THE FINAL DAYS OF THE
MONTH. AFTERNOON TEMPERATURES FELL INTO THE 30S AND RAIN CHANGED TO
SNOW ACROSS THE STATE. THE FIRST SNOWFLAKES OF THE SEASON WERE
OBSERVED NEARLY EVERYWHERE IN SOUTHWEST LOWER MICHIGAN. SNOW
ACCUMULATED IN NORTHERN AND PARTS OF CENTRAL LOWER MICHIGAN. NORTH
WINDS ACCOMPANYING THE SYSTEM ALSO BROUGHT GUSTS OVER 60 MPH AND
WAVE HEIGHTS OVER 20 FEET TO SOUTHERN LAKE MICHIGAN.
