High Pressure

My predictions from yesterday were very accurate due to the high pressure in the area.  For most of the day, the sun was out along with scattered clouds. The clouds today weren't as obvious to me.  After looking through the field guide, I'm still not totally sure.  They were definitely some type of cumulus though since they had the round, puffy features.  However, their changing sizes and patterns threw me off.

The temperature was fairly warm.  However, the position of the jet stream prevented it from being much warmer.  As shown in Figure 1, there is a significant trough in the jet stream.  This trough is bringing a cold, continental polar air mass south into our area.  If the trough in the jet stream moves farther east, then it could bring a warmer, continental tropical air mass north. This would increase the temperature in the area.

Based on the current high pressure, there will be minimal changes in the weather tomorrow.  Cloud cover will remain scattered.  No precipitation. However, temperature will increase due to a SW wind carrying a continental tropical air mass.
