Discussion... 
low clouds and fog resulted in slightly cooler conditions over the 
eastern Oklahoma and northeast Texas panhandles this afternoon and 
some adjustments were made for this. 


Overnight...temperatures will be near normal and winds should start 
to pick up late. On Thursday...warmer conditions will be the rule as 
southwest winds pick up. No major changes were made here from the 
previous forecast. 


Friday was the focus of this forecast package. An upper level system 
moves into the Southern Plains and brings cold air southward. A cold 
front drops into the panhandles on Friday bringing rain. This will 
create quite a difference in high temperatures from northwest to 
southeast as the colder air works southward. The timing of the front 
will keep the Oklahoma and the northern Texas Panhandle temperatures 
in the upper 30s and 40s while areas in the southeast Texas Panhandle 
climb to the upper 50s. As a result...maximum temperatures will occur 
earlier in the day in many locations and a non-diurnal pattern was 
followed for Friday. By later in the day Friday...rain will change 
quickly over to snow and for the overnight period. Winds will 
increase behind the front. 


On Saturday snow will linger into the afternoon hours before the 
system moves on to the east. Total snow amounts could range from one 
to four inches. Strong winds could add wind chill and blowing snow 
concerns. 


From Sunday through early next week...a dry warming trend is 
anticipated. Around the middle of next week another system could 
bring another shot of cooler air to the panhandles. 


Fire weather... 
fire weather concerns will remain low through next weekend. A sharp 
change in wind direction and speed is expected on Friday with the 
front.
