WEATHER SUMMARY  
NATIONAL WEATHER SERVICE PADUCAH KY  
406 AM CDT FRI MAY 22 2015  
 
THE COMBINATION OF PERSISTENT CLOUDS AND COOL NORTHERLY WINDS  
FROM CANADIAN HIGH PRESSURE MOVING SOUTH THROUGH THE UPPER MIDWEST  
ON THURSDAY HELPED TO KEEP HIGH TEMPERATURES IN THE UPPER 50S TO  
LOWER 60S FOR THE SECOND DAY IN A ROW.  
 
IN FACT...THE HIGH TEMPERATURES WERE SO COOL ON THURSDAY THAT  
SEVERAL RECORD MINIMUM HIGH TEMPERATURES WERE SET AT  
PADUCAH KENTUCKY...CAPE GIRARDEAU MISSOURI AND EVANSVILLE  
INDIANA. THESE LOCATIONS REPORTED HIGHS OF 63...61 AND 60  
DEGREES...ALL OF WHICH WERE LAST SET BACK IN 2002.  
 
THE CLOUDS FINALLY PUSHED OUT OF THE REGION BY 9 PM THURSDAY  
NIGHT.  
 
WITH SURFACE HIGH PRESSURE CENTERED OVER SOUTHEAST MISSOURI AND  
NORTHEAST ARKANSAS OVERNIGHT...CLEAR SKIES AND VERY LIGHT WINDS  
ALLOWED TEMPERATURES TO DROP SHARPLY THROUGH THE 50S...INTO THE  
LOWER AND MIDDLE 40S BY 3 AM CDT FRIDAY MORNING.  
 
ALTHOUGH THE HIGH PRESSURE CENTER NEAR THE SURFACE WILL SLOWLY  
MOVE EAST TODAY...HIGH PRESSURE ALOFT WILL DOMINATE THE REGION  
THROUGH SATURDAY...GRADUALLY WARMING TEMPERATURES TO NEAR NORMAL UNDER  
MOSTLY TO PARTLY CLOUDY SKIES.  
 
A LARGE AREA OF LOW PRESSURE WILL MOVE INTO THE CENTRAL ROCKIES  
OVER THE WEEKEND. WEATHER DISTURBANCES MOVING AROUND THIS WEATHER  
SYSTEM WILL INTERACT WITH AN INCREASING WARM AND MOIST FLOW OF  
AIR MOVING NORTH FROM THE GULF OF MEXICO.  
 
THESE WEATHER FEATURES WILL WORK TO GENERATE A DAILY CHANCE OF  
SHOWERS AND THUNDERSTORMS BEGINNING ON SUNDAY IN THE WEST...EXPANDING  
EAST AND PERSISTING OFF AND ON THROUGH MEMORIAL DAY AND INTO THE  
MIDDLE OF NEXT WEEK. GIVEN THE VARIABILITY IN THE LOCATION AND  
TIMING OF THE SHOWERS AND THUNDERSTORMS NEXT WEEK...THE ODDS OF  
A LONG TERM AND WIDESPREAD RAINFALL EVENT WILL LESSENED.  
 
TEMPERATURES IN AND OUT OF THE RAIN WILL RANGE FROM THE UPPER 70S  
TO LOWER 80S NEXT WEEK...WITH LOWS MAINLY IN THE 60S.
