Lightning Flash Density Past Week

May is going to come to a quiet end - although unusual cool has continued. Since the 21st six mornings brought low temperatures here at house down in the 40s. However, it looks like temperatures will be warming up as we begin June - NWS forecast indicates temperatures flirting with 100 F early next week here in Tucson.

The never-ending severe weather from the Plains to the East Coast has been the main story on national news for days now. I took a look at the CG flash density (from weather.graphics and Vaisala) for the past week ending at 7:00 am MST this morning. Plot above speaks for itself and is quite amazing.
