.DISCUSSION...
Our upper level flow becomes west to northwesterly by Tuesday,
resulting in a dry downsloping pattern. This may bring the
possibility of Red Flag conditions across our northern counties
by Tuesday afternoon with a more widespread fire weather concerns
on Wednesday. With minimum RH values tanking into the 10s and 20s
on Tuesday and 10s to single digits along with breezier conditions
for Wednesday, this will bring these elevated to critical fire
weather concerns into our region. The pattern looks to remain dry
through the remainder of the week into the early parts of the
weekend. By Sunday, a storm system may move in and increase
moisture into our CWA.
