.Discussion...
Limited potential for widespread wetting rain exists, but storms
capable of localized heavy rainfall are possible today and tonight
as a cold front crosses the region. Broad light rain is not out of
the question, especially in the I-80 corridor, but it will do
little to quell the excessive dry terrain. Little likelihood
exists for dangerous fire-weather conditions.
