=====================================================================
...AUTUMN IN FULL SWING WITH COOL, CLOUDY, AND BLUSTERY OCTOBER...
OCTOBER WAS MARKED BY THE DEVELOPMENT AND PERSISTENCE OF A HIGH
AMPLITUDE PATTERN IN THE UPPER ATMOSPHERE THAT BROUGHT ABOUT THE
KIND OF LARGE TEMPERATURE SWINGS TYPICAL OF THE FALL SEASON. THE
MONTH WAS MARKED BY 2 DISTINCT WARM PERIODS THAT SAW TEMPERATURES
RISE TO 70 DEGREES OR HIGHER DURING THE FIRST WEEK OF THE MONTH (OCT
1ST THROUGH OCT 5TH) AND AGAIN FOR AN EXTENDED PERIOD LAST SPANNED
THE THE 14TH OF THE MONTH THROUGH THE 26TH. IN BETWEEN, DAILY
AVERAGE TEMPERATURES FELL TO AROUND 10 DEGREES BELOW NORMAL AT
TIMES, WHICH IS NOT UNUSUAL FOR OCTOBER. HOWEVER, THE ACTIVE PATTERN
BROUGHT FREQUENT BOUTS OF WIDESPREAD CLOUD COVER WHICH HELPED
SUPPRESS DAYTIME HIGH TEMPERATURES WHILE INCREASING OVERNIGHT LOWS,
RESULTING IN A MONTH THAT SEEMED MUCH COOLER THAN OTHERWISE
SUGGESTED BY THE STATISTICS. IN ADDITION, CLIMATOLOGICALLY TYPICAL
BREEZY CONDITIONS ADDED AN EXTRA CHILL TO THE AIR ON MANY OF THE
DAYS.
DAYTIME HIGHS SOARED TO 77 AND 76 DEGREES ON OCTOBER 4TH IN THE
FLINT AREA AND SAGINAW RESPECTIVELY. HIGHS AGAIN ROSE WELL INTO THE
70S ON THE 24TH AND 25TH WHEN FLINT RECORDED AFTERNOON TEMPERATURES
OF 79 AND 78 DEGREES RESPECTIVELY. IN SAGINAW, HIGHS REACHED 76 AND
79 DEGREES, THE LATTER OF WHICH WAS A RECORD FOR THAT DATE AND
LOCATION. THE SURGES OF WARM AIR OCCURRED AHEAD OF DEEP TROUGHS THAT
WERE PROGRESSING ACROSS THE COUNTRY. IN THEIR WAKE, DAYTIME HIGH
TEMPERATURES FELL INTO THE 40S AND 50S WITH CLOUDY SKIES AND GUSTY
WINDS. IN ADDITION, TWO SYSTEMS BROUGHT SIGNIFICANT WIND TO
SOUTHEAST MICHIGAN OVER THE COURSE OF THE MONTH. THE FIRST, A STRONG
LOW APPROACHING TO THE WEST, BROUGHT WIDESPREAD WIND GUSTS AROUND 40
MPH ON THE 14TH AND 15TH. THE SECOND OCCURRED ON OCTOBER 29TH AND
30TH AND WAS ASSOCIATED WITH THE PHASING OF MID-LATITUDE ENERGY WITH
HURRICANE SANDY. THE RESULTING SYSTEM WAS QUITE LARGE IN SIZE AND
HAD AN EXPANSIVE WIND FIELD. GUSTS OF 45 TO 55 MPH WERE OBSERVED
ACROSS SOUTHEAST MICHIGAN, WITH MANY GUSTS OVER 60 MPH ALONG THE
SHORES OF LAKE HURON. AS NORTHERLY WINDS RAGED OVER THE LAKE, PORT
SANILAC SAW GUSTS REACH 65 MPH WHILE FORT GRATIOT RECORDED A
HURRICANE FORCE GUST TO 75 MPH. RAINFALL OCCURRED AT REGULAR
INTERVALS THROUGHOUT THE MONTH WITH LIGHT RAIN REPORTED ON 23 OF 31
DAYS IN FLINT AND 17 OF 31 IN SAGINAW, BUT NO SIGNIFICANT EVENTS OF
NOTE WERE RECORDED. FLINT`S MONTHLY TOTAL PRECIPITATION TOTAL OF
3.32" WAS 134% OF THE 2.47" MONTHLY NORMAL WHILE SAGINAW`S MONTHLY
TOTAL OF 3.36", GOOD FOR 128% OF THE 2.63" MONTHLY NORMAL. IN
ADDITION, BOTH LOCATIONS SAW THEIR FIRST MINOR SNOW ACCUMULATIONS OF
LESS THAN A HALF INCH ON OCTOBER 30TH.
THE AVERAGE HIGH TEMPERATURE FOR THE FLINT AREA WAS 60.7 (44TH
WARMEST), AND +1.1 DEGREES ABOVE THE NORMAL VALUE OF 59.6. THE
AVERAGE HIGH IN SAGINAW WAS 59.7 (61ST WARMEST ON RECORD), +0.4
DEGREES ABOVE THE 59.3 DEGREE NORMAL. FLINT`S AVERAGE LOW FOR THE
MONTH WAS 41.6 (34TH WARMEST ON RECORD), AND +2.2 DEGREES ABOVE THE
39.4 DEGREE NORMAL. SIMILARLY, THE AVERAGE LOW IN SAGINAW WAS 42.2
(32ND WARMEST ON RECORD), AND +2.1 ABOVE THE NORMAL OF 40.1 DEGREES.
THE AVERAGE TEMPERATURE FOR THE ENTIRE MONTH OF OCTOBER IN FLINT WAS
51.1 (42ND WARMEST), A DEPARTURE OF +0.6 DEGREES FROM THE 49.5
DEGREE OCTOBER NORMAL. FOR SAGINAW, IT WAS 50.9 (48TH WARMEST ON
RECORD), AND +1.2 ABOVE THE 50.9 OCTOBER NORMAL. IN ADDITION, THE
FLINT AREA`S AVERAGE TEMPERATURE OF 54.9 FOR 2012 TO-DATE (JAN 1 -
OCT 31) IS OUTPACING 1998 AS THE WARMEST AS THE WARMEST YEAR IN THE
HISTORICAL RECORD BY +1.2 DEGREES (AS OF OCT 31). LIKEWISE,
SAGINAW`S AVERAGE TEMPERATURE FOR THE YEAR-TO-DATE IS 54.6, BUT IS
ONLY +0.1 DEGREES ABOVE THE 55.5 DEGREE AVERAGE THAT WAS OBSERVED BY
THE SAME DATE IN 1998.
