Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0210 PM CDT Fri May 26 2017

Valid 271200Z - 281200Z

The elevated area for Day 2/Saturday has been expanded eastward
slightly into southwestern OK and more of the TX Panhandle. Across
this region, a surface dryline is forecast to mix eastward Saturday
afternoon, with sustained west-southwesterly winds of 15-20 mph
common behind it across the southern High Plains and parts of the
Southwest. The elevated area has also been expanded slightly to
include more of southeastern AZ and central NM. Latest guidance
suggests locally critical conditions may be realized across southern
NM into west TX where winds may exceed 20 mph for a couple hours
Saturday afternoon. However, these 20+ mph winds are expected to
occur on just a brief and isolated basis, which precludes the
introduction of a critical area with this update. See the previous
discussion below for more information.

...Synopsis...
An upper trough is expected to shift eastward into the central U.S.
on Saturday, as a ridge continues to build into the West. A surface
low over the southern High Plains at the start of the period is
expected to move northeastward into portions of the Midwest, as a
cold front sweeps through portions of the central/southern Plains. A
weak surface ridge will persist over Florida, resulting in hot and
dry conditions over portions of the interior peninsula, though winds
are expected to remain light.

...Portions of the Southwest into the Southern High Plains...
Surface winds are generally expected to weaken across the Southwest
into the southern High Plains compared to previous days, but
sustained winds of 15-20 mph, with locally higher gusts, are
expected during the afternoon. These winds, in conjunction with
minimum RH values below 15%, will result in elevated to locally
critical fire weather conditions from southeast Arizona eastward
into portions of the southern High Plains.
