..JULY MONTHLY CLIMATE NARRATIVE FOR NORTHERN AND EASTERN MAINE
 
 
SIMILAR TO JUNE, JULY WAS ANOTHER MONTH WITH ABOVE AVERAGE  
TEMPERATURES ACROSS NORTHERN AND EASTERN MAINE. TEMPERATURES  
AVERAGED FROM 2 TO 4.5 DEGREES ABOVE AVERAGE. IN CARIBOU, IT WAS  
THE 2ND WARMEST JULY ON RECORD BEHIND ONLY 2018. IT ALSO RANKED AS  
THE 2ND ALL-TIME WARMEST MONTH IN CARIBOU SINCE WEATHER RECORDS  
BEGAN IN 1939. IN HOULTON, IT WAS THE 11TH WARMEST JULY ON RECORD,  
IN MILLINOCKET THE 15TH WARMEST, AND IN BANGOR IT WAS THE 12TH  
WARMEST ON RECORD.  
 
THERE WERE A TOTAL OF 20 DAYS WITH A HIGH OF 80 DEGREES OR WARMER IN  
CARIBOU, WHICH IS THE 2ND MOST ON RECORD BEHIND ONLY 2018 WHEN THERE  
WERE 21 DAYS ABOVE 80F. MILLINOCKET ALSO HAD 20 DAYS WITH A HIGH OF  
80 DEGREES OR WARMER, WHICH WAS THE 9TH MOST ON RECORD. BANGOR AND  
HOULTON DID NOT RANK IN THE TOP 10 FOR THE NUMBER OF 80 DEGREE DAYS.  
 
FOR THE COMBINED 2-MONTHS OF JUNE AND JULY 2020 IT WAS THE ALL-  
TIME WARMEST ON RECORD IN CARIBOU BY A FULL DEGREE WITH AN  
AVERAGE 2 MONTH TEMPERATURE OF 67.2 DEGREES, WHICH BROKE THE  
RECORD OF 66.2 DEGREES IN 2006. IN HOULTON, IT RANKED AS THE 9TH  
WARMEST 2 MONTH PERIOD, IN MILLINOCKET IT RANKED AS THE 7TH  
WARMEST, AND IN BANGOR IT WAS THE 11TH WARMEST.  
 
MODERATE DROUGHT CONDITIONS WERE OBSERVED ACROSS ALL OF NORTHERN  
AND EASTERN MAINE IN JULY WITH A MUCH SMALLER AREA OF SEVERE  
DROUGHT ACROSS PARTS OF THE SAINT JOHN VALLEY. NEAR RECORD LOW  
STREAM FLOWS WERE REPORTED ACROSS AROOSTOOK COUNTY, ESPECIALLY  
DURING THE FIRST HALF OF THE MONTH. SHORT TO VERY SHORT TOPSOIL  
MOISTURE WAS REPORTED IN MANY AREAS OF NORTHERN AND EASTERN MAINE.  
THE DRY CONDITIONS IMPACTED AGRICULTURAL INTEREST WITH REDUCED  
HAY AND GRAIN CROPS AND LED TO AN INCREASED NEED TO IRRIGATE  
CROPS.  
 
THE MONTH BEGAN VERY DRY, BUT RAINFALL DID BECOME MORE FREQUENT  
FROM THE 2ND WEEK OF THE MONTH THROUGH THE END OF THE MONTH. IN  
CARIBOU, A TOTAL OF 3.04 INCHES OF RAIN WAS OBSERVED, WHICH WAS  
ABOUT 75 PERCENT OF NORMAL. IN HOULTON, 3.13 INCHES OF RAIN FEEL,  
WHICH WAS JUST 53 HUNDREDTHS OF AN INCH BELOW NORMAL. IN  
MILLINOCKET, 4.02 INCHES OF RAIN FELL, WHICH WAS 17 HUNDRETHS OF  
AN INCH ABOVE AVERAGE. IN BANGOR, 4.21 INCHES OF RAIN WAS  
OBSERVED, WHICH WAS THREE QUARTERS OF AN INCH ABOVE AVERAGE. THE  
RAINFALL WAS A COMBINATION OF MOSTLY SHOWERS AND THUNDERSTORMS,  
AND MANY AREAS IN WASHINGTON COUNTY AND NORTHERN AROOSTOOK COUNTY  
HAD WELL BELOW AVERAGE RAINFALL THAT RANGED FROM AS LITTLE AS 25  
PERCENT OF NORMAL IN PARTS OF THE SAINT JOHN VALLEY TO 5O TO 70  
PERCENT OF NORMAL IN WASHINGTON COUNTY. EVEN LOCATIONS THAT DID  
EXPERIENCE CLOSER TO AVERAGE MONTHLY RAINFALL WAS NOT ENOUGH TO  
OVERCOME THE TOTAL MONTHLY EVAPORATION OF 5.14 INCHES (AS MEASURED  
AT CARIBOU) DUE TO ABOVE NORMAL TEMPERATURES AND AMPLE SUNSHINE THIS  
MONTH.  
 
FOR THE 2-MONTH PERIOD OF JUNE AND JULY IT WAS THE 3RD DRIEST ON  
RECORD IN CARIBOU WITH ONLY 3.92 INCHES OF RAIN. HOULTON HAD THE  
5TH DRIEST JUNE AND JULY COMBINED WITH 4.31 INCHES. MILLINOCKET AND  
BANGOR DID NOT RANK IN THE TOP 20 FOR THE DRIEST COMBINED JUNE AND  
JULY ON RECORD.  
 
THE OUTLOOK FOR THE MONTH OF AUGUST IS CALLING FOR CONTINUED  
GREATER PROBABILITIES OF ABOVE NORMAL TEMPERATURES. THERE IS AN  
INCREASED PROBABILITY OF ABOVE AVERAGE PRECIPITATION ACROSS THE  
DOWNEAST REGION AND NO STRONG CLIMATE SIGNALS THAT WOULD POINT  
TOWARD ABOVE OR BELOW AVERAGE PRECIPITATION ACROSS THE REMAINDER  
OF THE REGION. AVERAGE TEMPERATURES BEGIN TO SLOWLY FALL,  
ESPECIALLY DURING THE 2ND HALF OF THE MONTH. IN CARIBOU, THE  
AVERAGE HIGH ON THE 1ST IS 76 DEGREES AND IT FALLS TO 71 BY THE  
END OF THE MONTH. THE AVERAGE LOW DROPS FROM 55 ON THE 1ST TO 49  
BY THE END OF THE MONTH. ON AVERAGE, THERE IS 3.76 INCHES OF RAIN.  
IN BANGOR, THE AVERAGE HIGH FALLS FROM 80 DEGREES ON THE FIRST TO  
76 BY THE END OF THE MONTH. THE AVERAGE LOW FALLS FROM 58 TO 53  
DEGREES. NEARLY AN HOUR AND A HALF OF DAYLIGHT IS LOST DURING THE  
MONTH OF AUGUST.
