Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0344 PM CDT Wed Mar 21 2018

Valid 231200Z - 291200Z

An extended period of elevated to critical fire weather conditions
is expected across portions of the southern Rockies and adjacent
central/southern Plains. An upper ridge centered over the Plains
early Day 3/Friday will shift east as a shortwave trough migrates
across the Rockies. Enhanced deep-layer westerly flow will stream
across the region and a lee cyclone will track east/southeast across
the central Plains during the afternoon. A dryline will extend
southward from the low from central KS into western OK and
west-central TX. Behind the dryline, gusty west/southwest surface
winds and very dry conditions are expected. Elevated to critical
fire weather conditions are expected to encompass portions of
eastern CO, western KS, northwestern OK into the OK/TX Panhandles,
western TX, southern and eastern NM and far southeast AZ.

On Day 4/Saturday, a larger-scale upper trough will dig across the
western U.S. A brief period of upper ridging will occur over the
Plains on Saturday before more amplified ridging ensues across the
eastern U.S. The eastern ridge is expected to block eastward
progression of the western trough. This will result in several lee
cyclones migrating off the High Plains and elevated to critical fire
weather conditions developing behind the dryline each day into early
next week.
