"ZONAL FLOW" MEANS DRY WEATHER

We have a zonal flow pattern my frieds this week! That means a general west to east jet stream with just little "bumps" or "short waves" in the Jet that have to travel far enough south, and be positioned just right to give us any precipitation at all. This eventually will change and a more major trough (U shape in the Jet) will develop in the Jet Stream pattern, perhaps as early as this weekend, but until that time tranquility reigns. The chart you are looking at is for Tuesday at the 500mb, or 18,000 ft. level.
