...UNSEASONABLY COOL REGIME CONTINUES...

A LARGE HIGH PRESSURE SYSTEM WILL CONTINUE BE ENTRENCHED OVER
SOUTHERN CANADA AND THE UPPER MIDWEST...KEEPING CHILLY WEATHER IN

COMBINE WITH COLD AIR ALOFT TO FORM CUMULUS CLOUDS TODAY. ALSO...MID
LEVEL CLOUDS WILL ACCOMPANY AN UPPER LEVEL DISTURBANCE DROPPING DOWN
ACROSS THE AREA FROM THE NORTH. THIS WILL MAKE FOR A GENERALLY PARTLY
CLOUDY SATURDAY...ALTHOUGH THERE MAY BE MOSTLY CLOUDY SPELLS AT TIMES
THIS AFTERNOON OVER EAST CENTRAL IOWA AND NORTHWEST ILLINOIS. A FEW
INSTABILITY SHOWERS WILL EVEN BE POSSIBLE THIS AFTERNOON NORTHEAST OF
A MANCHESTER...TO QUAD CITY LINE. ALONG WITH THE CLOUDS...SOME LATE
MAY SUNSHINE WILL ALSO BE SEEN TODAY AND SHOULD HELP BOOST AFTERNOON

SOME LOW LYING AREAS NORTH OF THE INTERSTATE 80 CORRIDOR MAY EVEN
DROP INTO THE LOWER 30S. THUS AREAS OF FROST WILL AGAIN FORM ALONG
AND NORTH OF THE INTERSTATE 80 CORRIDOR AFTER MIDNIGHT...POSING A
THREAT TO TENDER OUTSIDE VEGETATION. SINCE IT IS THE GROWING
SEASON...PEOPLE WITH TEMPERATURE SENSITIVE PLANTS OUTSIDE WILL WANT
TO TAKE THE NECESSARY PRECAUTIONS TO PROTECT THEM. RECORD LOWS FOR
MAY 19TH ARE GENERALLY IN THE MID 30S...AND WILL BE IN JEOPARDY OF
BEING TIED OR BROKEN.
