A weak lead upper level trough was moving southeast across northern MO and eastern KS. The stronger ascent ahead of the H5 trough digging southeast out of southern Canada Tonight and Tuesday will remain well north and northeast of the CWA. The resulting low-level CAA across the northern plains will cause a surface cold front to push southward across the CWA after midnight.
A TROUGH OVER THE GREAT LAKES REGION CONTINUES ITS NORTHEASTWARD PROGRESSION HEADING TOWARDS QUEBEC AND ONTARIO OR THE EASTERN PROVINCES OF CANADA.

300 AM CST TUE JAN 12 2016 Early this morning, a cold front is dropping into northern Missouri with a few light snow showers associated with it. Strong cold air advection behind this cold front will bring cold conditions to the area today with highs in the teens across northern Missouri and the 20s elsewhere. Moderate northwest winds this morning will subside as Canadian high pressure builds into the area. High pressure will shift east of the area early tonight and winds will return from the south.
248 AM CST TUE JAN 12 2016 08Z water vapor imagery shows northwest flow aloft with a long wave trough over the northeastern quarter of North America and upper level ridging over the southwest U. This is mainly due to limited moisture and the expected dry air that will advect into the area this morning behind the cold front. The shot of cold air appears to be brief as the consensus in the models is for the ridge to slide east by this afternoon and southwesterly winds develop late in the day bringing warm air back into the area. Temps overnight should be non-diurnal on account of the low level warm air advection progged by the models.
901 PM CDT FRI JUN 5 2015 WEAK COLD FRONT HAS SLIPPED SOUTH OF MOST OF THE FORECAST AREA, ALTHOUGH OUR COUNTIES IN SOUTHEAST ILLINOIS WILL HAVE THE FRONT IN THE VICINITY FOR A BIT LONGER.

1245 AM EDT SAT JUN 6 2015 HIGH PRESSURE CENTERED OVER THE NORTHEASTERN UNITED STATES WILL RIDGE SOUTH ALONG THE EASTERN SEABOARD THROUGH THE WEEKEND.
Low temperatures still look to be in the low to mid 60s overnight. At 2pm EDT a weak surface trof stretched from Cleveland to Indianapolis to Kansas City. As this trof sinks southward this evening it may provide enough forcing to spark a few showers or a thunderstorm or two. Low temperatures for tonight are somewhat tricky, given our cooler than expected temps last night and a light north breeze tonight. Will aim for lower and middle 60s, but wouldn't be surprised if we ended up getting a little cooler than that. Saturday will be dry as we sit on the edge of a dome of high pressure over the Great Lakes. Highs will be in the lower and middle 80s. Lows will again center around the lower 60s.
THE UPPER LOW BETWEEN LAS VEGAS AND LOS ANGELES WILL CONTINUE TO LIFT NE OVERNIGHT.
