Regional Weather: Eastern North America

Generally dry with showers possible South. The weather situation will be much like it was over the past few days. High pressure remains firmly entrenched over eastern North America, with fronts staying to the west and north. Pesky post-tropical cyclone Jose slowly exits the New England coast. Dry weather is dominant. Scattered showers will occur in parts of the South each day. Major Hurricane Maria, now north of Hispaniola, is turning to the north and should remain well offshore the southern Atlantic coast. Expect few, if any, weather impacts from Maria until next week. Warm to hot with highs well into the 80s and 90s, lows in the 60s and 70s.

 

OUTLOOK:

Overview: Epidemic spread unlikely most regions, possible in the South. Conditions are unfavorable for survivable transport and deposition of airborne spores during the nearly all the transport events coming out of the northern and central regions. A daily hodge-podge of conditions is expected for the events emanating from the southern sources, only a few of which generate High risk. Transport events tend to move near the sources in most cases.
