.Short Term...(Today through Saturday) Issued at 309 AM EDT Fri May 14 2021
 Early this Morning...high pressure continues to be the main weather
feature across the eastern third of the country.  So, the radar mosaic and
GOES16 are quiet across central Indiana.  Any activity at this time is
confined to the central and western portions of the U.S. where a stationary
boundary is draped between two surface lows over Utah and Nebraska. 
Currently, temperatures across central Indiana are generally in the 40s
with calm winds and significant radiational cooling.  Today/Tonight...skies
will initially be clear this morning with time cross sections showing a dry
column until the early afternoon. At that point though, skies will become
partly cloudy as moisture increases in the mid levels.  Nonetheless, there
will still be plenty of sunshine.  And, as easterly winds shift to the
south this afternoon, weak warm advection will commence.  Daytime highs are
progged to top off in the upper 60s/low 70s.  Tonight, the warm advection
will continue as a warm front pushes farther into the Missouri Valley, but
central Indiana will still be under the influence of high pressure.  So,
will trend toward a dry forecast with overnight lows climbing back into the
upper 40s/low 50/s  Saturday...the area of high pressure will finally push
eastward into West Virginia/Virginia, and a weak wave will break down the
ridge aloft.  Meanwhile, that aforementioned warm front will be just to the
southwest of the forecast area as an additional source of forcing.  As a
result, will have to insert mention of rain showers from west to east
across the forecast area starting Saturday morning.  The progression will
be slow, however, with the eastern half of central Indiana still dry on
Saturday afternoon. And, daytime highs will top off in the low 70s in the
warm, southerly flow.
