.DISCUSSION...
A ridge of high pressure building aloft will raise temperatures
through Saturday with high temperatures becoming 5 to 10 degrees
above normal Friday and Saturday. This trend will also reduce
thunderstorm chances on Friday to just isolated coverage in the
afternoon and evening. Minimum relative humidity values Friday
and Saturday fall to 15-20 percent in desert locations while
winds overall will be light and under 12 mph. Deeper moisture is
expected to return through the weekend with increasing
thunderstorm chances late Saturday afternoon through the
evening. Any thunderstorm may come with the threat of strong
gusty winds and heavy rain. Daily chances for thunderstorms
return in the following days into next week. Minimum relative
humidity values should rise as well Sunday through the first
half of next week.
