.DISCUSSION...
A weak disturbance pushing toward the Great Lakes region will
continue to bring rain chances to portions of the area through the
morning hours today, mainly across south central Nebraska. Notable
accumulations are not expected. The forecast for this afternoon
remains dry, with skies expected to continue to be at least partly
cloudy. Winds are forecast to be on the breezy side today, with
surface high pressure to our north keeping winds east-northeasterly.
Sustained speeds around 15 to 30 mph are expected, with gusts near
25 to 30 mph. Thanks to a cooler air mass settling across the
area, high temperatures are forecast to range from the mid 40s in
the north to mid-upper 50s in the south.
