The upper-level pattern remains quiet for our area. Below shows the upper-level jet pattern across the CONUS. The same system which brought the cold front through us yesterday is now in Minnesota.

Gorgeous weather on this Thursday. After the cold frontal passage and some storms last evening across northern sections of our viewing area, today will be strictly amazing.
