Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0334 PM CDT Sat Mar 17 2018

Valid 191200Z - 251200Z

Elevated fire weather conditions will persist on Day 3/Mon across
portions of the southern High Plains into south Texas. Strong
westerly deep-layer flow will continue across the region as a series
of weak shortwave impulses track across the southern Plains. At the
surface, a strong pressure gradient will be oriented across the High
Plains on the back side of a deep low over northeast OK. Strong
northwest surface winds around 15-20 mph with higher gusts will be
widespread as RH values fall into the 10-20 percent range from
southeast NM into southwest TX. A larger area of elevated fire
weather conditions is expected across eastern NM, much of western
into central and southern TX as a very dry airmass overspreads the
region behind a cold front. The northern and eastern extent of fire
weather potential is likely to shift over the coming days as
forecast confidence increases with regards to potential cloud cover
impacting RH, and where areas of greater rainfall occur across
central or southern TX in the Day 2 period associated with frontal

A lull in fire weather potential will occur Days 4-5/Tue-Wed as an
upper ridge builds across the western states and slowly shifts
across the Rockies to the Plains around Days 6-7/Thu-Fri. As the
ridge shifts east and breaks down, this could lead to another period
of higher-end fire weather potential across parts of the
central/southern Rockies and adjacent Plains.
