.PREV DISCUSSION /417 AM MST/...The low that brought the very strong
winds and rain/snow to the region has started to move further to
the north and east of the area early this morning. While the
center of the low will be a bit more removed from our area, the
pressure gradient doesn't fully relax and today will once again be
on the breezy side. While not nearly as strong as they were on
Sunday, we can expect wind gusts around 25-35 mph through this
afternoon.

The low pushes to the north, but it starts to cut off and retrograde.
This will allow for some of its energy to rotate through the mid
level flow on Tuesday along with the pressure gradient starting to
tighten up again, With no moisture left to push through, do not
expect any form of showers to develop. However, the winds will
become quite gusty and might near Wind Advisory levels, especially
across portions of northern and eastern Arizona. Wind gusts in the
the 35-45 mph range are possible. Near critical fire weather
conditions are also possible across far eastern Arizona on Tuesday.

The low further retrogrades and sinks to the south. As the low
pushes to the south we should actually see the gradient weaken so
expect lighter winds, more typical spring breeziness, as we go
through the week. Additionally, this low will keep the cooler air in
place across northern Arizona.

The low finally starts to break down and push to the east at the end
of the week. Again, with limited moisture do not expect any showers
to develop, though best chances for a stray, isolated shower would
be over the Four Corners region.

Ridging returns over the weekend with warming temperatures across
the region.
