We should get some decent melting done on Monday with highs ranging from the upper 30s across central Missouri to the lower 40s across extreme southern Missouri and along the I-49 corridor. A reinforcing shot of cold air will also filter into the region behind a passing cold front. All operational models indicate a large scale pattern which would be supportive of a panhandle hook type system with low pressure developing across the southern high Plains and then tracking east/northeast through our region. As is usually the case with these types of systems, the low track would play a key role in precipitation type.
229 AM EST MON JAN 11 2016 HIGH PRESSURE OVER THE CENTRAL CONUS WILL GRADUALLY BUILD EAST INTO THE REGION TODAY. A REINFORCING COLD FRONT WILL CROSS THE AREA TUESDAY WITH DRY AND COOL CONDITIONS PREVAILING THROUGH THE END OF THE WORK-WEEK. AS HIGH PRESSURE. CURRENTLY CENTERED OVER THE LOWER MISSISSIPPI VALLEY.
