DATA SOURCE: US ARMY CORPS OF ENGINEERS LOCK STATUS REPORT AT HTTP://CORPSLOCKS.USACE.ARMY.MIL/LPWB/F?P=121:4:0::::: ******************************************************************* CURRENT CONDITIONS AS OF 11/25/14: SEE THE COMMENTS ABOVE FOR DETAILS. OUTLOOK FOR NEXT 7 DAYS: Air temperatures were generally 10 to 25 degrees below normal last week which led to significant ice formation and growth from LD1 to LD15. A temporary warm up this past weekend slowed ice growth and caused some melting and break up. A return to below normal air temperatures is forecast for this week with another brief warm up on tap for this coming weekend. IN OUR REGION...LOW TEMPERATUREs THIS MORNING RANGED FROM 4 DEGREES AT BEMIDJI MN TO 10 DEGREES IN MINNEAPOLIS MN TO 17 degrees at LD15 to 30 degrees at St Louis. Air temperatures will generally remain below freezing north of LD 15 or 16 this week. Temperatures should rise above freezing on Friday all the way north to La Crosse WI and on Saturday all the way to St Cloud MN. High temperatures should be in the 40s and 50s in St Louis on Friday through Sunday. BASED ON THESE FACTORS...WE ANTICIPATE THAT ICE development will resume this week...mostly north of LD 15 or 16. Ice development and growth should slow down this coming weekend in the north...and we should melt some ice in the south... especially during windy periods. According to news sources...this year was the earliest end to shipping on the Upper Mississippi River in 45 years. THE NEXT ICE STATEMENT WILL BE RELEASED ON TUESDAY..DEC 2 2014. ...BSITES... $$
