  15. Okay, this is some of the thickest smoke aloft that I've seen here thus far. The sun is still relatively dark and deep orange/pink two hours after sunrise.

  19. I just realized that the record at IAD for today is 91F tied in 2009. So IAD has broken the daily record by 2F thus far.

DISCUSSION AND OUTLOOK ---------------------- At 100 PM CDT (1800 UTC), the center of Tropical Storm Arlene was located near latitude 26.7 North, longitude 86.2 West. Arlene is moving toward the south near 5 mph (7 km/h) and this motion is expected to increase slightly through tonight. Maximum sustained winds have increased to near 40 mph (65 km/h) with higher gusts. Arlene is expected to weaken by tonight, and it is forecast to degenerate into a remnant low on Saturday. Tropical-storm-force winds extend outward up to 70 miles (110 km) northeast of the center. The estimated minimum central pressure based on data from the Air Force Hurricane Hunters is 1002 mb (29.59 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Rainfall amounts of 1 to 2 inches with localized higher amounts up to 5 inches are possible through Saturday across portions of the central and southern Florida Peninsula. This rainfall is not directly related to Tropical Storm Arlene. Regardless, the heavy rainfall could lead to isolated flash, urban, and small stream flooding impacts. NEXT ADVISORY ------------- Next complete advisory at 400 PM CDT. $$ Forecaster Cangialosi/Hogsett/Delgado
