tropical moisture lingers... (pm.09.sep.14)>

Tuesday's stats:

Low temp: 63.5F (17.5C)
High temp: 71.6F (22.0C)
Rainfall: 0.14" (4mm)

Our beautiful early morning sunshine didn't last very long -- giving way to a lot of thick cloudiness and occasional fog before 11:00am.  There were even a few brief sprinkles of rain around noon, with a brief but heavier shower (with thunder) right around 4:00pm that actually delivered a quick few millimeters of rain.  Here at sunset, we've got a mix of clouds, fog, and peeks of sun.

The tail-end of the monsoon season is often characterized by lingering latent moisture in the air mass that can quickly turn a sunny day into a cloudy, foggy and showery one.  Every year we go through this -- everyone has a passionate desire to be able to say a final GOOD-BYE to the monsoon, but it can tend to linger on and deceive us a few times before it finally departs for good.  And honestly, the 9th of September is still too early!

The weather charts and data look fairly encouraging as far as the trend over the course of the next week to ten days is concerned.  But I'm still not seeing the definitive and decisive push of dry air from the northwest (throughout the multiple layers of the atmosphere) that is necessary to permanently displace this left-over tropical moisture.  Stay mentally prepared for the development of clouds, patchy fog, and mainly afternoon rain showers as we wait out this transition period...
