.DISCUSSION...
Near perfect radiation cooling overnight as sfc high pressure
bringing clear skies and near calm winds across the region. Most
overnight lows will sink to the lower to middle teens by daybreak.
A full diurnal rebound of 25 to 30 degrees from overnight lows
will yield aftn highs near 40 to the mid 40s. Warming trend into
wknd with increased warm air advection. Thickening low lvl clouds
with this increased south winds will result in Fri night temps
only falling a few degrees from daytime readings. Instability to
increase and saturated low lvls with much drier air aloft will
result in possible lgt showers within shallow moist layer late
Friday night thru early Sunday.  Deepening upper trough with
associated low over central plains on Sunday will bring rapidly
deepening moisture, along with increased low lvl shear. Question
mark will be instability with possible lack of sfc heating in
cloud cover. Depending on this factor, some locally heavy rainfall
and strong gusty winds may be possible in a few storms. Drier air
arriving Monday after this trough will bring overnight lows into
the 30s, but lack of colder Canadian air may limit any freezing
temps for most of the rest of the month./07/
