...RAIN AND SNOW MELT WILL BRING RISES AND POTENTIAL FLOODING TO
AREA RIVERS LATER THIS WEEK...

MILD TEMPERATURES HAVE MELTED OFF A MAJORITY OF THE SNOW PACK OVER THE
LAST FEW DAYS. WATER CONTENT OF THE SNOW PACK PRIOR TO THE MELT WAS
AS HIGH AS 1 TO 2 INCHES OVER PORTIONS THE UPPER ROCK...FOX...AND
DES PLAINES WATERSHEDS. SOIL MOISTURE REMAINS ABOVE NORMAL. FROST
WAS OUT OF THE SOIL IN AREAS ALONG AND SOUTH OF INTERSTATE 80. A
SHALLOW LAYER OF FROST REMAINED IN THE SOIL IN AREAS NORTH.

A SLOW MOVING STORM SYSTEM WILL BRING PERIODS OF RAIN TO THE AREA
THROUGH THE END OF THE WEEK. TOTAL RAINFALL AMOUNTS BY THE END OF
THE WEEK COULD BE AS HIGH AS 1 TO 1.5 INCHES WITH SOME OF THE
HEAVIEST RAIN TOTALS OVER THE ROCK...FOX...AND DES PLAINES RIVER
BASINS....ALTHOUGH MANY AREAS IN NORTHERN ILLINOIS COULD
EXPERIENCE TOTALS OF NEARLY ONE INCH.

THIS RAINFALL OCCURRING DURING THE MELT PERIOD COULD RESULT IN MINOR
TO MODERATE FLOODING IN SOME LOCATIONS...WITH THE SEVERITY OF ANY
FLOODING DEPENDING ON THE AMOUNT OF ADDITIONAL RAINFALL RECEIVED
THIS WEEK. RIVER CRESTS WOULD OCCUR THIS WEEKEND WITH SOME
LOCATIONS NOT CRESTING UNTIL EARLY NEXT WEEK. EVEN WITH LITTLE OR
NO RAINFALL...SOME LOCATIONS ON RIVERS IN THE NORTHERN THIRD OF
ILLINOIS COULD SEE RISES TO NEAR OR SLIGHTLY ABOVE FLOOD STAGE AS
A RESULT OF RUNOFF FROM SNOW MELT ALONE.

RESIDENTS IN LOW LYING FLOOD PRONE AREAS ALONG AREA RIVERS SHOULD
CONTINUE TO CLOSELY MONITOR LATER WEATHER AND RIVER FORECASTS AND
STATEMENTS FROM THE NATIONAL WEATHER SERVICE REGARDING THE FLOOD
POTENTIAL THIS WEEK.

WEATHER FACTS
WHAT ARE THE GLOBAL WIND PATTERNS?
The equator receives the Sun's direct rays. Here, air is heated and rises, leaving low pressure areas behind. Moving to about thirty degrees north and south of the equator, the warm air from the equator begins to cool and sink. Between thirty degrees latitude and the equator, most of the cooling sinking air moves back to the equator. The rest of the air flows toward the poles.
