Area forecast discussion 
National Weather Service Norman OK 
544 am CST Thursday Nov 26 2015 

the 12z aviation discussion follows.... 


rain will spread NE across North Texas and OK this morning...bringing 
lower ceilings and visibilities to the region. Conditions are 
likely to be imc this afternoon at most taf sites. +Ra late this 
afternoon and evening will bring visibilities down at times to 
less than 1 sm. While there is a possibility of thunderstorms and rain...they should 
be limited to isolated flashes of lightning in otherwise Ordinary 
rain showers. A strong cold front will sweep southeast across the region today 
and this evening...bringing abrupt wind shifts and swiftly falling 
temperatures. The actual timing of the front may be an hour or two 
different from the its speed is difficult to gauge at 
this point. As the cold air continues to flow into the region 
overnight...temperatures in northwest OK should fall below freezing. 
Some freezing rain is likely after 06z...reaching as far as kelk-kcsm- 
kjwg-kend by 12z. Low clouds...restricted visibilities...and areas 
of freezing rain in the west...will continue tomorrow...with some improvement 
beginning Saturday. 


Previous discussion... /issued 452 am CST Thursday Nov 26 2015/ 

a strong cold front will pass through Oklahoma and North Texas 
today and overnight...bringing major changes to our weather. At 
the same time...exceptionally large quantities of moisture in the 
atmosphere will result in heavy rain...mainly in the general 
vicinity of the front...and in the colder air behind it. 

At 430 am...the cold front was in far northwest Oklahoma...from 
northwest of Alva to the Antelope Hills. This front will move 
southeast through the day...reaching the Oklahoma City area early 
this evening...Wichita Falls by midnight...and the southeast 
corner of our forecast area near Durant tomorrow morning. 
Temperatures will drop swiftly after frontal passage...generally 
dropping almost immediately from the 60s to the 40s...and wind 
chills will be mainly in the 20s and 30s in the colder airmass. 

As the cold air continues to strengthen across the region...much 
of western and northern Oklahoma...and parts of western North 
Texas...will have temperature readings fall below freezing. The 
rain will continue...resulting in freezing rain. Some sleet...and 
maybe snow...will fall in far northwest Oklahoma at times...but we 
currently expect freezing rain to be the main type of 
precipitation northwest of the freezing line. 

We have upgraded the Winter Storm Watch to an Ice Storm Warning as 
confidence in significant ice accumulations...1/4 inch or 
more...has risen. In addition...there is some potential for 
significant ice accumulations a little bit east and south of our 
former watch we have issued a Winter Storm Watch for a 
thin area from Perry to Oklahoma City to Lawton to Vernon and Knox 
City Texas. There was also a need to expand the Ice Storm Warning 
into Hardeman and Foard counties in the current outlook 
brings quite a bit of ice into those counties as well. 

The eastern/southeastern edge of the watch/warning area will 
probably only see accumulations on trees...power lines...and other 
exposed/elevated surfaces. Travel problems are unlikely in those 
areas...except where downed tree limbs might block a few streets. 
Farther northwest...especially from around Hobart to Watonga...the 
outlook is less desirable...and travel problems will be fairly bridges and overpasses will probably become 
slippery...and greater accumulations of ice on trees/power lines 
may become a serious problem. Warm ground temperatures should 
preclude ice on the ground or non-elevated highways...except 
possibly in northwest Oklahoma where colder temperatures will 
hang around longer. 

While the northwest half or so of our forecast area is dealing 
with ice...the southeast half will likely see very heavy rainfall. 
As mentioned earlier...there will be a lot of moisture for the 
storm system to work with...and by the time it moves away on 
Sunday and Monday...5 to 8 inches of rainfall is expected 
along/southeast of I-44. The heaviest rain is expected in our far 
southeast counties. A Flash Flood Watch was already in 
effect...and for the far southeast counties...we are extending the 
watch another 24 hours. 

The weather finally settles down Sunday night...and a warming 
trend begins on Monday. Temperatures will recover to near the 
seasonal average around the middle of next week...with readings 
ranging from the middle 40s to the middle 50s.
