A new week, a new season

Sure enough, it feels like autumn after Saturday’s cold frontal passage and wild weather which included a “tornado” reported in Fairfax county (never verified by the National Weather Service).  The bright blue sky, cool temperatures, and dryer air all signify a farewell to the summertime “hot and stickies.”   This is borne out by this morning’s satellite view of the U.S. showing the water vapor content of the air:

The darker and clearer portions are the dry air that swept in from Canada behind the cold front.  You can see it’s all the way into northern Florida.

The big question is:  how long will it stay this way?  After a dry and sunny week with temperatures maxing out in the upper 70′s and low 80′s (F) it looks like another cold front will sweep through late this coming weekend, possibly bringing in even cooler air.  This far out it’s too early to call but it does appear that we could swing to a cooler-than-average pattern next week.

Meanwhile the tropics are still somewhat active, although Tropical Storm Leslie and Hurricane Michael have been “fish storms” to date.  Leslie looks like she may graze Newfoundland as a minimal hurricane before transitioning into a strong “extra-tropical storm” and hitting the southern tip of Greenland and then Iceland.  There is another disturbance way out in the Atlantic that has been assigned a 90% probability of developing into a tropical storm, but it is still too early to tell where this one may head.

Enjoy the wonderful weather this week!
