...FLASH DROUGHT TO CONCLUDE THE MONTH...

THE MONTH STARTED NOTABLY COLD WITH A TRACE OF SNOWFALL AND AN
AVERAGE TEMPERATURE DEPARTURE THROUGH THE 4TH OF ABOUT 12 DEGREES
BELOW NORMAL. CHEERFUL SPRING WEATHER ARRIVED SOON AFTER WITH HIGHS
IN THE 70S AND 80S. A COUPLE OF SOAKING THUNDERSTORMS (7TH AND 12TH)
ACCOUNTED FOR 3.08 INCHES OF THIS MONTH`S 4.06 INCH PRECIPITATION
TOTAL. THESE TWO SOAKING RAIN EVENTS PROVIDED A BUFFER AHEAD OF THE
VERY DRY CONDITIONS THAT DEVELOPED LATE IN THE MONTH. THE QUICK
ONSET OF DRY CONDITIONS IS KNOWN AS A FLASH DROUGHT.

THIS FLASH DROUGHT WAS A RESULT OF AN OMEGA BLOCK (AS WELL AS A REX
BLOCK LATER ON) OVER THE REGION WHICH CUT-OFF THE FLOW OF MOISTURE
TO OUR LOCAL AREA, WHILE HIGH PRESSURE STEERED ANY SHOWER AND STORM
CHANCES ELSEWHERE.

DRY WEATHER PERSISTED FOR 11 STRAIGHT DAYS WHICH HAS OCCURRED
NUMEROUS TIMES (RANKS AS AS 215TH OVERALL, TIED AS 19TH LONGEST
BASED ON NUMBER OF DAYS, WHERE 41 DAYS IS THE LONGEST ENDING
SEPTEMBER 27, 1908) IN THE PERIOD OF RECORD. THE RECORD BOOKS ALSO
SHOW THAT, IN INSTANCES OF 11 CONSECUTIVE DRY DAYS OR MORE, THE
ENDING DATE WAS IN MAY 15 TIMES. EIGHT OF THOSE 15-TIMES HAVE AN END
DATE IN THE FINAL 10-DAYS OF THE MONTH. RECENT STRETCHES OF DRY
WEATHER INCLUDE JUNE 25, 2022, WHEN A 12-DAY DRY STRETCH ENDED. THE
YEAR 2021 FEATURED FOUR DIFFERENT DRY PERIODS, RANGING FROM 16 DAYS
(ENDING MAY 25) TO 11 DAYS. ALL THAT TO SAY, THESE PROLONGED
STRETCHES OF DRY WEATHER DO OCCUR SOMEWHAT OFTEN IN THE AREA.

ON ONE HAND, THIS DRY WEATHER WAS BENEFICIAL FOR THOSE CUTTING HAY
AND PLANTING. ON THE OTHER HAND, SUCH A LONG STRETCH OF DRY WEATHER
CAUSED CONCERN FOR NEWLY-PLANTED CROPS.

PRECIPITATION TOTALED 4.06 INCHES WHICH RANKS AS THE 75TH DRIEST ON
RECORD. THE PRECIPITATION TOTAL IS 0.52 INCHES BELOW NORMAL.

A TRACE OF SNOW WAS RECORDED ON MAY 1, WHICH IS ABOVE-NORMAL FOR THE
MONTH AND IS THE 4TH SNOWIEST ON RECORD FOR THE MONTH. MAY 2020 ALSO
FEATURED A TRACE OF SNOW.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 73.4 DEGREES WHICH IS 1.2
DEGREES ABOVE NORMAL. ONE 90-DEGREE DAY WAS RECORDED; ON THE 30TH.
THIS IS 15 DAYS AHEAD OF THE NORMAL START DATE OF 90-DEGREE
TEMPERATURES, JUNE 13TH.

TWO PRECIPITATION RECORDS WERE BROKEN THIS MONTH. ON THE 7TH, 1.53
INCHES BROKE THE PREVIOUS RECORD OF 1.08 INCHES IN 2004. ON THE
12TH, 1.55 INCHES BROKE THE PREVIOUS RECORD OF 1.05 INCHES SET IN
1914.
