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.
