Update
We have issued a winter weather advisory for tonight.

Discussion
Temperatures have dropped below freezing across northwest oklahoma
(at 645 pm, the freezing line was from cheyenne to taloga to
cherokee), and we have started to receive reports of scattered
slippery spots on bridges in extreme northwest oklahoma. Radar and
surface observations suggest that drizzle is falling over
scattered parts of northwest oklahoma.

The drizzle is expected to expand southeast with time, as
temperatures similarly drop from northwest to southeast. This will
result in (at least) patches of freezing drizzle through early
Sunday. Based on the current situation and the expected trends, a
winter weather advisory appears to be warranted for much of west-
central, central, northwest, and north-central oklahoma. The
advisory runs until 9 am Sunday, by which time the risk of ice on
roads should end.

concerns for this TAF update include ceiling restrictions and low
probabilities of drizzle and or light precipitation as
temperatures cool to near freezing.

Strong cold front has passed all terminals except ksps, where
passage is imminent. Low stratus is gradually spreading south in
wake of the front, and will envelope all sites by around 18 01-03z.

Ifr lifr ceilings will be widespread and persistent. Biggest
questions remains likelihood of precipitation. All forcing ascent
appears shallow, generally focused over south-central ok red river
valley, and generally occurs in advance of the surface freezing
line. Current obs radar suggest some light drizzle freezing
drizzle in northern oklahoma now. Have indicated brief periods of
light freezing drizzle at kwwr and then at kpnc and kcsm between
18 05-09z before relatively drier air advects south.

Note, prospects for freezing drizzle do not currently appear
impactful at kokc, but we continue to monitor.

cold front that is currently from stillwater to near altus ok
will continue to move across the area the rest of this afternoon
into this evening. Breezy north winds, clouds, and colder air will
move in behind the front. Temperatures have been falling shortly
after the frontal passage. Drizzle and or light rain will be
possible tonight into Sunday morning across portions of the fa.

Some of the precipitation could become freezing drizzle and or
freezing rain overnight. With any freezing precip expected to be
light and patchy along with being over a relatively short period
of time in any one location due to drier air moving into the
region, will not issue a winter weather advisory at this time but
if the freezing precipitation ends up being heavier and or over a
longer period of time an advisory may be needed on later shifts.

Sunday will be cold with highs in the 30s and 40s. However, the cold
conditions will be brief with temperatures warming back up into the
50s and eventually 60s next week. Models show an upper ridge
developing over the rockies with a shortwave undercutting the base
of the ridge and then moving across the southern plains. This
shortwave could bring a chance for rain to southern parts of the fa
although still some question as to path of this system which would
have an impact of location of rain, if it occurs at all. Otherwise,
conditions will remain dry and relatively mild through Thursday.

Models show an upper trough moving across the plains late next week
which could bring another chance for rain to parts of the fa. This
trough will be the first in several systems that the models show
could affect the region through next weekend which may bring
additional precipitation chances.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
