OUTLOOK FOR NEXT 7 DAYS: AIR TEMPERATURES AND DEW POINTS WERE WELL ABOVE NORMAL FROM FRIDAY OF LAST WEEK THROUGH YESTERDAY...AND IT RAINED OVER MUCH OF THE UPPER MIDWEST. THAT MELTED A LOT OF SNOW AND ICE. THIS COMBINATION IS ADDING SOME VOLUME TO THE RIVERS AND IS HELPING TO BREAK UP ANY REMAINING ICE. IT IS ALSO PRODUCING NEW FRAZIL ICE IN SOME OF THE NORTHERN TRIBUTARIES. AIR TEMPERATURES SHOULD BE NEAR NORMAL TO A LITTLE ABOVE NORMAL THIS WEEK AND NEXT. IN OUR REGION...LOW TEMPERATURES THIS MORNING WERE 20 DEGREES IN ST CLOUD MN...23 IN THE TWIN CITIES...AND 41 DEGREES AT ROCK ISLAND AND ST LOUIS. AIR TEMPERATURES SHOULD REMAIN BELOW FREEZING FOR THE NEXT WEEK NORTH OF ABOUT ROCK ISLAND...WITH LOW TEMPERATURES IN THE TEENS AND LOW 20S. HIGH TEMPERATURES SOUTH OF THERE SHOULD BE IN THE 30S AND LOW 40S. AT THIS TIME WE ARE NOT SEEING ANY BIG ARCTIC OUTBREAKS FOR THE NEXT 10 DAYS. BASED ON THESE FACTORS...ICE DEVELOPMENT AND GROWTH SHOULD RESUME NORTH OF ABOUT LD15 THIS WEEK INTO NEXT WEEK. WE PROBABLY WILL NOT SEE ANY NEW ICE DOWNSTREAM OF ABOUT LD17 OR LD18. THE NEXT ICE STATEMENT WILL BE RELEASED ON TUESDAY..DEC 23 2014. ...BSITES... $$
