.DISCUSSION...
(Tonight through next Tuesday)
Issued at 1111 PM CST Tue Dec 9 2025

Benign weather continues ahead of an approaching upper level low
and attendant cold front. Southerly flow ahead of the front has
allowed temperatures to warm into the upper 40s, with a few areas
squeaking into the 50s. The pressure gradient will tighten
further tomorrow ahead of the cold front for another breezy and
mild day. Probabilities of 40 mph wind gusts (Wind Advisory
Criteria) from the NBM generally range from 30-60% in
northeastern Arkansas, the Missouri Bootheel, and far northwest
Tennessee. Hi-res guidance is not quite as bullish for criteria
being met, so we are holding off on issuing a Wind Advisory with
this package, but one could be issued by morning.

The first of a series of cold fronts will cross tomorrow with
very little effect other than gusty winds. Thursday morning will
be chilly post frontal under northwest flow. Thursday morning
lows will be in the upper 20s and lower 30s. Temperatures could
be a bit warmer than that if any post-frontal stratus develops
and lingers. Return flow at the surface will allow temperatures
to rebound quickly Thursday afternoon before a reinforcing cold
front crosses on Friday night. The airmass behind Friday`s front
is of Arctic origin and cool weather will filter in. Strong
surface high pressure and a brisk northerly wind will bring quite
the chill to the Mid-South. Apparent temperatures are likely to
dip to around 10 degrees over far northeast Arkansas, the
Missouri Bootheel, and northwest Tennessee Sunday morning. The
coldest air temperatures will reside on Monday morning as a
perfect radiational cooling night looks to set up.

There is a chance (25-50%) of precipitation Saturday evening.
Current forecast indicates temperatures will be above freezing at
the onset of precipitation. We will need to monitor the timing of
precipitation as it does hover near the freezing mark after
midnight into Sunday morning. Temperatures will rebound as an
upper level ridge will center over the lower Mississippi Valley
by the middle of next week.

.AVIATION...
(12Z TAFS)
Issued at 539 AM CST Wed Dec 10 2025

A few more hours of LLWS ahead of the approaching cold front
(high confidence). Gusty SW surface winds will veer to NW as the
front moves through. A couple of hours of increased winds (high
confidence) right behind the front. Winds will quickly diminish
later this afternoon into this evening. VFR conds will prevail
through the period (high confidence).

.FIRE WEATHER...
Issued at 1111 PM CST Tue Dec 9 2025

Strong southwesterly winds will continue through most of the day
Wednesday, filtering in moisture to raise minimum humidity levels
to 40 to 55 percent. This pattern will generally persist through
the rest of the week before an Arctic cold front passes on Friday
night.
