.SHORT TERM...
(This evening through Sunday)
Issued at 155 PM CST Sat Jan 2 2021

Water vapor imagery this afternoon shows an upper low moving 
across eastern Oklahoma, with zonal flow aloft over our region, 
while visible satellite showed sunny skies across our forecast 
area. At the surface, west to southwest winds were occurring due 
to low pressure across eastern CO and high pressure over deep 
south Texas. As of 130 pm, temperatures were in the upper 40s to 
mid 50s, which is generally about 10-15 degrees warmer than 24 
hours ago. This warming is due to warming of the 850 mb thermal 
ridge and the warmer downsloping westerly surface flow. 

Tonight and Sunday, the low will continue moving off to the 
northeast while a trailing surface low from eastern CO moves 
southeast through the Red River region, keeping our winds in a 
westerly direction. The 850 mb thermal ridge will strengthen a 
little further tonight and tomorrow which, along with the warmer, 
downsloping westerly winds, should lead to a little warmer lows 
tonight (low to mid 30s) and warmer highs Sunday (mid 50s to mid 
60s). Mostly clear skies should continue.
