A Red Flag Warning remains in effect until 8 PM this evening for portions of New Jersey, all of Delaware and most of the Maryland Eastern Shore.

For the rest of today, west winds continue generally around 15-20 with frequent gusts in the 25-30 mph range. Peak gusts up to 35 mph will be possible across far southeastern Pennsylvania and across the coastal plains of southern new Jersey and Delmarva. Relative humidity is forecast to fall to around 20% to 35% for most areas, lowest across Delmarva and the Pine Barrens of New Jersey where highs will be in the 60s to around 70. Overnight relative humidity recovery tonight will be around 60% to 70% with winds diminishing to 5 to 10 mph by the overnight period.

By Wednesday, conditions will improve somewhat compared to today in terms of winds. West to northwest winds will be around 10 to 15 gusting to around 20 mph however relative humidity is still forecast to fall to around 30% across much of the area.

For Thursday and Friday, the minimum relative humidity is currently forecast to be around 30 percent during each day (potentially a little lower Friday due to much warmer temperatures). The winds however are forecast to be less, sustained at 10-15 mph.

A Red Flag Warning us in effect until 8 PM this evening for all of New Jersey

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. Additionally, a Special Weather Statement has been issued for our Pennsylvania forecast zones, since the current fuel moisture does not meet Red Flag criteria for those areas.

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.
