Unusually Warm Nights Summer 2010 and

Very Dry August Across Eastern OK and Northwest AR

While afternoon temperatures and heat index values were hot this summer, it was actually the overnight low temperatures that had been exceptionally warm the entire summer across the area.  High pressure dominated the Southern Plains this summer, keeping a moist airmass in place over the region.  The higher humidity levels kept temperatures from cooling much during the overnight hours, allowing for many consecutive days with minimum temperatures at or above 70°F.  Both Tulsa, OK and Fort Smith, AR had the most consecutive days with temperatures at or above 72°F.  Summer 2010 ranked as the 3rd warmest summers on record in Fort Smith and as the 6th warmest summer on record in Tulsa due to these warm overnight temperatures combined with the hot afternoon high temperatures.  See the tables below for additional statistics.  Drought conditions also develop during August 2010 (click here to jump to dry August information below).
