MONDAY NIGHT...

.DISCUSSION...Hot, dry, and unstable southwesterly flow will
continue today, with relative humidity values falling to near 10
percent during the afternoon. Very poor overnight RH recoveries
are expected, with winds increasing further Monday as a trough
approaches the area. Combined with the hot and very dry airmass,
this will result in critical fire weather conditions. The trough
will pass through the area late Monday into Tuesday, bringing a
decrease in winds and temperatures and a small increase in
relative humidity. However, the dry and breezy conditions will
return late in the upcoming week as high pressure rebuilds.
