Frost possible Saturday morning

Another chilly day for central Indiana Friday.  One difference, there will be more sunshine today than there was Thursday.  Temperatures should top out in the middle-50°s this afternoon.

High-resolution computer models suggest we will see more clouds pushing in to central Indiana later Friday afternoon.  A fetch of moisture is projected to move off Lake Michigan in to northwest Indiana.  This will be mainly in the way of cloud cover, but spotty showers could be possible.

The clouds will likely move south and eventually east over the CBS4 viewing area.  The clouds may help keep temperatures up a few degrees overnight.  Where clouds remain intact, lows may only fall to around 40°.  Elsewhere, temperatures should fall in to the middle and upper 30°s.

Saturday will be another cool day for central Indiana.  High temperatures should be a couple degrees warmer than Friday, but remaining in the 50°s.

ANOTHER CHANCE FOR STORMS

Long range computer models are advertising a fast moving piece of energy moving through the upper-levels of the atmosphere.  It will create an area of low pressure in the lower-levels and bring a cold front through the area later Wednesday.

Upper-level disturbance is expected to move through the Midwest mid-week.

At this distance, a few strong to severe thunderstorms could be possible, but it is far from set in stone.  Continue to monitor forecasts over the next several days to see if the thinking changes.
