Expect quiet weather today as surface high pressure remains in control across the region. Predominately easterly surface flow will result in negligible thermal advection, keeping temperatures almost identical to yesterday. Look for highs in the upper 60s to lower 70s under mostly sunny skies. Latest satellite imagery does depicts some high clouds pushing through central Indiana this morning from a subtle impulse aloft. These clouds will continue moving eastward with sunny skies expected later today.
