Discussion:
With the Low finally off to our East, we will see very calm weather for the first part of this week. High temperatures will be in the low 70's and the lows will be in the high 40's to low 50's. A clear sky will be predominant through Tuesday night, with some increasing clouds through Wednesday into Wednesday night.

Technical Discussion:
As this morning's low pressure system moves a ridge builds over the Midwest. We decided to use the GFS 20 as it had a better grasp of the temperatures. Both models were close in visualizing the ridge and the departure of the low. The NAM ran a couple of degrees hotter than the GFS. We also used the NBM to aid in temperature forecasting.
At the 250 MB level, a ridge continues to move through mid-Missouri. This ridge looks to stay over the Midwest till this weekend.
Mid-levels of the atmosphere are showing weak levels of vorticity as the High makes its way through the Midwest. Low levels of moisture follow this ridge as there is lack of vertical velocity signatures.
At the 850 MB level, the beginning of this week will be dryer but the lower level jet (LLJ) will bring moisture from the Gulf as High pressure systems over Alabama and Mississippi move off to the east. The earliest outlooks see a chance for clouds Wednesday and Wednesday night.
Surface temperatures will continue to rise as the week progresses. This is due to the lack of clouds and the change in winds. Winds will begin to switch from the West to the South tonight. Lows will stay in the mid forties throughout this week but will rise to the fifties due to the arrival of the LLJ Wednesday. Dewpoints will stay distanced from our temperatures showing little saturation in the atmosphere. Dewpoints increase during the week and increase coinciding with the arrival of the LLJ.
