...SALEM 2018 WEATHER IN REVIEW...

================================================================
2018 MONTHLY WEATHER HIGHLIGHTS...

JANUARY...RATHER MILD, BUT DAMP JANUARY. RAIN FELL ON 24 DAYS,
     WITH THE WETTEST PERIOD BETWEEN THE 20TH AND 27TH. A STRONG
     FRONT ON THE 22ND BROUGHT GUSTY SOUTH WINDS, WITH PEAK GUSTS
     OF 40 TO 45 MPH, CREATING SPOTTY POWER OUTAGES.

FEBRUARY...MILD WEATHER CONTINUED INTO EARLY MONTH, CAPPED WITH
     TEMPERATURES IN THE LOWER 60S FROM 2ND TO 4TH. THEN, MORE
     TYPICAL FEBRUARY TEMPERATURES RETURNED, ALONG WITH RAIN AT
     TIMES. A COLD FRONT BROUGHT MUCH COLDER AIR INTO THE REGION
     FROM THE 18TH TO 23RD, WITH AFTERNOON HIGHS IN THE UPPER 30S.
     RAIN TURNED TO SNOW ON 21ST, WITH MINOR ACCUMULATIONS. MILD
     TEMPERATURES RETURNED TO CLOSE THE MONTH. BUT MAIN STORY
     WAS THE RAINFALL SHORTFALLS, WITH FEBRUARY RAINFALL ONLY
     ABOUT HALF OF WHAT IS NORMALLY EXPECTED.

MARCH...RATHER TYPICAL MARCH, WITH THE USUAL UPS AND DOWNS WITH
     TEMPERATURES, BUT NOTHING EXTREME. A STRONG FRONT SWEPT
     ACROSS THE REGION ON THE 8TH, WITH GUSTY SOUTH WINDS. THE
     WINDS GUSTED 35 TO 50 MPH ACROSS THE CENTRAL WILLAMETTE
     VALLEY, WITH GUST OF 43 MPH AT THE SALEM AIRPORT. FAIRLY
     WET FROM 22ND INTO 23RD, WITH 1.42 INCHES OF RAIN.

APRIL...FINALLY, A MONTH IN WHICH RAINFALL WAS AT LEAST NORMAL,
     THOUGH ONLY BY ABOUT A HALF INCH. WET AND COOL TO START
     APRIL. STRONG FRONT ROLLED ACROSS REGION ON THE 7TH, WITH
     1.64 INCHES OF RAIN. THIS RAINFALL MADE APR 7 THE 2ND
     WETTEST DAY EVER IN APRIL FOR SALEM. GUSTY WINDS 40 MPH
     DAMAGED SOME TREES, WITH ONE DOWNED TREE BLOCKING HIGH
     STREET NEAR CROSS STREET TO SOUTH OF BUSH PARK. RATHER
     MILD WEATHER FROM THE 19TH TO 26TH, WITH TEMPERATURES WELL
     ABOVE NORMAL. WARMEST DAY ON THE 25TH, WITH HIGH OF 84 DEG.

MAY...TO THE DELIGHT OF GARDENERS, MAY BROUGHT WARM DAYS AND
     A LOT OF DRY DAYS. MOST ACTIVE WEATHER OCCURRED FROM
     8TH TO 10TH, DURING WHICH SHOWERS AND A FEW THUNDERSTORMS
     OCCURRED. BUT, WITH ONLY A TOTAL OF 0.21 INCH OF RAIN, IT
     WAS THE 4TH DRIEST MAY ON RECORD (RECORD DRIEST MAY WAS
     1992 WHEN SALEM ONLY GOT 0.05 INCH OF RAIN).

JUNE...A QUITE PLEASANT, BUT UNEVENTFUL JUNE. MAJORITY OF THE
     RAIN FOR THE MONTH FELL BETWEEN THE 8TH AND 11TH. AFTER
     THE 16TH, LITTLE IF ANY RAIN FELL. WITH THIS DRY WEATHER,
     TEMPERATURES WARMED INTO THE 80S AND EVEN 90S AT TIMES,
     WITH HOTTEST DAY BEING ON THE 19TH WITH 92 DEG.

JULY...GREAT SUMMER MONTH FOR OUTDOOR ACTIVITIES, WITH WARM
     AND DRY DAYS. THERE WERE 26 DAYS WITH TEMPERATURES OF
     AT LEAST 80 DEG, AND 17 DAYS THAT WERE AT LEAST 90 DEG.
     EVEN THOUGH IT WAS A WARM, IT WAS NOT RECORD WARMTH.
     RATHER, JULY 2018 FINISHED AS THE 3RD WARMEST JULY FOR
     SALEM. BUT, IT WAS DRY, JUST A FEW DROPS ON 4TH AND 9TH.

     BIG NEWS FOR JULY WAS THE INCREASE OF WILDFIRES ACROSS
     SOUTHERN OREGON. THE UMPQUA COMPLEX TO SOUTHWEST OF
     CRATER LAKE, AND THE KLONDIKE FIRE TO WEST OF GRANTS
     PASS, AND OTHER FIRES BURNED ACTIVELY UNDER THE VERY
     WARM AND DRY CONDITIONS. SMOKE FROM THESE FIRES DRIFTED
     NORTH OVER CENTRAL WILLAMETTE VALLEY FROM TIME TO TIME.

AUGUST...NEARLY A CARBON COPY OF JULY, AS WAS WARM AND DRY.
     RAIN RECORDED ON ONLY 2 DAYS, WHEN A TRACE FELL ON 27TH
     AND 30TH. SMOKE FRONT FIRES OVER SOUTHWEST OREGON LOFTED
     NORTH INTO THE AREA FROM TIME TO TIME. A NEW LARGE FIRE,
     THE TERWILIGER FIRE, BROKE OUT ON THE 18TH AND 19TH,
     BURNING OVER 11,000 ACRES OF TIMBER IN EAST LANE COUNTY.

SEPTEMBER...YES, WARM AND DRY WEATHER CONTINUED. BUT FRONTS
     DID BRING RAIN AT TIMES AFTER THE 10TH. BUT STILL NOT A
     LOT OF RAIN, AS SALEM ONLY GOT 0.35 INCH FOR WHOLE MONTH.
     THE WATER YEAR, WHICH CAPTURES THE FULL RAINY SEASON,
     ENDED 30 SEPTEMBER, WITH 34.25 INCHES, ABOUT 5 INCHES
     BELOW NORMAL.

     THE STRETCH OF DRY DAYS THAT STARTED 12 JUNE CONTINUED
     INTO SEPTEMBER, BUT ENDED ON SEPT 9TH, MAKING IT 90
     CONSECUTIVE DAYS WITH NO MEASURABLE RAIN (ZERO OR TRACE
     ONLY). PREVIOUS RECORD WAS 79 DAYS, BACK IN 1967.

     IF REMOVE THE DAYS THAT WITH A TRACE, THEN 2018 SAW A
     STRING OF 32 CONSECUTIVE DAYS WITH NO RAIN (NOT A DROP),
     FROM 10 JUL TO 10 AUG. (RECORD IS 73 DAYS IN 1914).

OCTOBER...MILD WEATHER CONTINUED INTO OCTOBER. BIT OF RAIN
     FELL ON THE 5TH TO 9TH, BUT THEN WAS DRY THROUGH 24TH.
     THEN, JUST LIKE THAT, SUMMER WAS OVER. AFTER SEEING
     TEMPERATURES IN THE LOWER TO MID 70S THROUGH THE 22ND,
     AFTERNOON TEMPERATURES PEAKED ONLY IN THE 50S TO MID 60S
     AFTERWARDS. AND THE RAIN RETURNED. IT WAS THE MOST RAIN
     SEEN IN THE AREA SINCE MID APRIL.

     THE DRY MILD DAYS AND COOL NIGHTS ALLOWED FOR IDEAL
     CURING OF TREE FOLIAGE, PROVIDING SOME SPECTACULAR
     DISPLAYS OF AUTUMN COLOR.

NOVEMBER...VERY ODD MONTH, WITH DRY WEATHER FROM 6TH TO 20TH.
     NOVEMBER SAW MILD TEMPERATURES AND BELOW NORMAL RAINFALL.
     MORE ACTIVE WEATHER RETURNED BY THANKSGIVING, WITH RAIN
     AT TIMES. BUT IT WAS TOO LATE, AS NOVEMBER WOULD CLOSE
     AFTER GETTING A BIT MORE THAN HALF OF THE NORMAL RAIN.

DECEMBER...FINALLY, A MONTH THAT SOMEWHAT RESEMBLED WEATHER
     MORE TYPICAL OF WINTER, WITH RAIN AND BREEZY CONDITIONS
     FROM TIME TO TIME. RATHER STRONG FRONT ON THE 14TH BROUGHT
     SPOTTY POWER OUTAGES AND BROKEN TREE BRANCHES AS SOUTH
     WINDS GUSTS 40 TO 50 MPH. ANOTHER BREEZY FRONT SWEPT ACROSS
     THE WILLAMETTE VALLEY ON THE 18TH, WITH WINDS GUSTS
     OF 40 TO 50 MPH, AND 1 TO 2 INCHES OF RAIN.
