.PREV DISCUSSION... /ISSUED 307 PM CST WED FEB 10 2016/

DISCUSSION...
Fire weather conditions teetering on the edge of critical
thresholds in some locations west of U.S. Highway 75 this
afternoon, but so far the wind speeds have remained less than 20
mph with a few gusts pushing 25 mph. Basically, about as close as
you can get to Red Flag criteria without actually meeting it with
temps 65-70 and RH 20-25%. At this time we do not anticipate any
upgrade from Fire Wx Watch to Red Flag Warning as no significant
increase in wind speeds is anticipated, though spread rates still
require extreme caution.

A weak cold front will push through later tonight with a shift to
north winds for Thursday, resulting in a modest cool down to
afternoon highs near normal. Temps will then rebound some on
Friday ahead of a much stronger Canadian cold front, which will
move into northern areas Friday afternoon and the rest of the area
Friday night. The brunt of the coldest air will remain to our
northeast, however as warm advection kicks in late Saturday and
early Sunday, expect light precip to develop. Expected thermal
profiles support some winter precip across far northeast OK and
northwest AR through Sunday morning before airmass warms enough
for all rain by afternoon. No significant impacts are expected at
this time, but there will be a window of opportunity for some
light icing roughly FSM-BVO north. Better forcing arrives later
Sunday across southern areas, thus the best chance of significant
rainfall looks to be south of I40 Sunday afternoon and evening.

Still appears a return to much above normal temps will take place
next week upper ridge builds across the central U.S.
