...RED FLAG WARNING IN EFFECT FROM 11 AM THIS MORNING TO 8 PM EDT THIS EVENING...


.DISCUSSION...

Low daytime relative humidity is forecast through the remainder of the week. Critical fuel moistures continue to dry out as we get further away from the most recent wetting rains. This will continue to result in fire weather concerns for the next few days, but especially for today as breezy conditions persist.

For today, conditions will be somewhat less significant compared to Tuesday in terms of winds. West to northwest winds will be sustained around 10 to 15 mph with frequent gusts around 20-25 mph. The winds will be on the lower end of the aforementioned spectrum for Delmarva. Relative humidity is forecast to fall to around 20% to 30% across much of the area. Some minimum values near 15% are possible across Delmarva. Forecast high temperatures are well into the mid to upper 60s across the area, and near 70 degrees across Delmarva.

A Red Flag Warning has been issued for New Jersey, which is in effect from 11 AM to 8 PM today. A Special Weather Statement has been issued for our Maryland and Delaware forecast zones, since the current wind forecast does not meet Red Flag criteria for those areas. Additional coordination will be needed later this morning to determine if any fire weather danger products will beneeded for Pennsylvania.

For Thursday and Friday, relative humidity will continue to fall to around 30% across the area, although winds will be notably less around 10 mph during the daytime hours.
