northwest flow aloft will remain over the area through the next 24

set a record low for today and yesterday. The previous record for
today was 49 degrees, and for yesterday was 50 degrees. A record
low of 48 was set for the 23rd of May, and we have gotten down to
48 so far this morning as well. A weak pressure gradient in
surface ridging today--will tighten up tonight as lee surface
troughing in southeastern Colorado intensifies. As a result, light
and variable winds this morning will shift to west/southwest by
this evening, then increase to 10 to 20 mph out of the
south/southwest during the overnight hours. Not only will we be
dry, very few clouds Temperatures today will warm back into the
