...JANUARY HIGHLIGHTS...
...MEASURABLE SNOW IN TUCSON...
...COOLEST JANUARY SINCE 1979...
...26TH COOLEST JANUARY ON RECORD...

THE NEW YEAR STARTED OUT WITH UNSETTLED WEATHER WITH SEVERAL WEAK 
LOW PRESSURE SYSTEMS MOVING THROUGH ARIZONA. THESE SYSTEMS BROUGHT 
VERY LITTLE PRECIPITATION TO THE AREA...WITH GENERALLY LESS THAN A 
TENTH OF AN INCH RECORED WITH ANY ONE SYSTEM. THE 8TH TO THE 11TH OF 
THE MONTH BROUGHT A STRONG RIDGE OF HIGH PRESSURE...WITH VERY WARM 
AFTERNOON TEMPERATURES. THE TUCSON INTERNATIONAL AIRPORT RECORDED 
71...75...75 AND 71 DEGREES RESPECTIVELY ON THESE DAYS...WHICH IS 6 
TO 10 DEGREES ABOVE THE NORMAL HIGH FOR THE MONTH OF JANUARY. 

TOWARD THE MIDDLE OF THE MONTH A PATTERN CHANGE TOOK PLACE BRINGING 
STRONG...COLD LOW PRESSURE SYSTEMS TO SOUTHEAST ARIZONA. SYSTEMS 
IMPACTING THE AREA THE 12TH THROUGH THE 16TH OF THE MONTH BROUGHT 
RECORD AND NEAR RECORD LOW TEMPERATURES...AS WELL AS NEAR RECORD LOW 
MAXIMUM TEMPERATURES FOR AT LEAST ONE DAY. THE TUCSON INTERNATIONAL 
AIRPORT RECORDED HIGH TEMPERATURES THE 13TH THROUGH THE 16TH OF 
51...45...50 AND 57 DEGREES RESPECTIVELY. THE SAME DATES RECORDED 
LOW TEMPERATURES OF 36...24...20 AND 27 DEGREES. ALTHOUGH THESE 
STORM SYSTEMS BROUGHT VERY COLD TEMPERATURES TO THE REGION...THEY 
BROUGHT LITTLE TO NO RAINFALL. THE TUCSON INTERNATIONAL AIRPORT 
RECORDED 0.02 INCH ON THE 10TH AND A TRACE OF RAIN ON BOTH THE 11TH 
AND THE 12TH. OTHER LOCATIONS THROUGHOUT THE TUCSON METRO AREA 
RECORED MORE RAINFALL...BUT ALL UNDER A TENTH OF AN INCH.

A BREAK IN THE WEATHER BROUGHT NEAR NORMAL TEMPERATURES FOR A COUPLE 
OF DAYS BEFORE TWO MORE STORM SYSTEMS MOVED INTO THE AREA. THE FIRST 
SYSTEM BROUGHT 0.24 INCH OF RAIN TO AIRPORT WITH OTHER LOCATIONS 
RECORDING A TENTH TO AN INCH OF RAIN. THE SECOND SYSTEM...ONLY A DAY 
LATER PLAYED OFF THE LEFT OVER MOISTURE AND DUMPED 0.37 INCH OF RAIN 
AT THE AIRPORT AS WELL AS A TRACE OF SNOW. THE TUCSON AREA IN 
GENERAL RECEIVED ONE HALF INCH TO TWO INCHES OF SNOWFALL ON THE 21ST 
OF THE MONTH. THIS SNOW OCCURED IN THE EVENING AS SNOW LEVELS 
QUICKLY CRASHED TO THE VALLEY FLOORS. THE LAST TIME THAT THE TUCSON 
INTERNATIONAL AIRPORT RECORDED MEASURABLE SNOW WAS JANUARY 31 OF 
2002.  

TOWARD THE END OF THE MONTH TEMPERATURES SOARED BACK UP TO NEAR AND 
ABOVE NORMAL. THE LAST COUPLE DAYS OF THE MONTH BROUGHT ANOTHER 
STORM SYSTEM THAT PRODUCED A TRACE OF RAIN AT THE AIRPORT. OVERALL 
JANUARY WAS A MONTH OF VERY UNSETTLED WEATHER WITH A LITTLE BIT OF 
EVERYTHING (ABOVE NORMAL TEMPERATURES...BELOW NORMAL 
TEMPERATURES...RECORD LOW TEMPERATURES...RAIN AND SNOW).  

OVERALL THE MONTH OF JANUARY WAS THE 26TH COOLEST ON RECORD WITH AN
