Temperatures in the 100s over southwest Nebraska. Even with

keeping temperatures from torching out as in the drier air, with
dew points in the 30s and 40s to the west southwest. Have numerous
boundaries across western Nebraska today from convection south
and north last night. Fairly high convective clouds developing
this afternoon with temperatures hovering around the century mark.
Little vertical extent. Cloud field from Curtis to Hyannis and

Platte. Waiting for initiation. Lows tonight in the 50s and 60s.

Highs on Thursday with the cold front moving south will be in the

sensible weather Saturday night and have gone with consensus with
showers over southwest nebraska through the evening. Still not
