.DISCUSSION /Through Monday/...
Issued at 101 PM MDT Mon Mar 30 2026

It`s another day of above normal temperatures, with DIA in the
upper 70s as of early this afternoon. There is potential that we
tie another record high today, but we might fall just short of the
record (record high for this date is 82 degrees set in 2010).
There`s also a very good chance we break the record for the
warmest low temperature for this date. Our current low temperature
for today at DIA is 51 degrees and we are not expecting to fall
below this temperature again today. The current record for the
warmest low temperature for this date is 49 degrees (set in 1913).

The cold front will move through overnight, entering our northern
counties along the WY border around midnight and moving south out of
our southern counties by the early morning. Winds behind the front
will be breezy from the north/northeast, with gusts around 25 to
45mph. The strongest wind gusts are expected to be in our
northeastern Colorado counties. There are some low end precip
chances (
