Day 3-8 Fire Weather Outlook

Valid 221200Z - 281200Z

The general pattern of an amplified upper ridge over the Southwest
and an upper trough covering much of the central and eastern CONUS
is expected to hold through most of the extended period. Fire
weather concerns are expected to remain relatively low for most of
the period, though some threat may evolve on Friday across the
Plains as a strong cyclone moves across southern Canada. Weak
offshore flow will persist until this weekend across southern
California, but forecast winds are currently light enough to
preclude a more substantial threat in that area.

...D5/Friday: Portions of the Great Plains...
Relatively warm, dry, and windy conditions are expected across much
of the Plains on Friday, as a strong cyclone moves across the
southern Canadian prairies. There is some potential for elevated to
locally critical conditions ahead of and immediately behind a cold
front that will sweep across the central/northern Plains, but too
much uncertainty remains regarding the timing of the front and the
potential for critically low RH to introduce any probabilities at
this time. Some threat may extend further south into portions of the
southern High Plains where critically low RH is likely, but flow
will weaken with southward extent and the potential for large-scale
critical conditions appears too low for any probabilities in that
area.
