Marine Weather and Tide Forecast for Deale, MD

NEAR TERM /THROUGH FRIDAY/

Cdfnt has moved southeast of Cumberland and is seen on radar as a broken line of light showers. Isolated to scattered light showers will remain possible over the next couple of hours.
Otherwise, clearing skies and less humid conditions are expected overnight. Winds will shift to NW behind the cold front.

SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/
The humidity finally lowers along with a brief reprieve in the excessive heat as we round out the workweek. Strong upper-level ridging and surface high pressure will build over the eastern CONUS through the start of the weekend. The surface high and upper-level ridge will continue to strengthen each day bringing warming temperatures and eventually more humidity. For Friday, expect highs back in the mid 80s with dewpoints in the 50s and low 60s. Overnight lows Friday night will fall into the upper 50s and low 60s west of the Blue Ridge with mid to upper 60s in the metro areas. A spotty shower or t-storm cannot be ruled out in northwest flow late Friday afternoon and evening as a weak piece of trailing shortwave energy slides north and east of the area. Highest confidence for this to occur would be along the PA/MD line and west of the Catoctins. For now, hedged PoPs to less than 15 percent given ample dry air advection settling in with building surface high.

Low humidity continues Saturday although temperatures push back into the upper 80s and low 90s under light southerly flow. Lows Saturday night will drop back into the mid to upper 60s and low 70s. Humidity will gradually increase during this time as broad 1024-1028 mb high pressure strengthen off the Carolina coast.

LONG TERM /SUNDAY THROUGH THURSDAY/
A strong ridge of high pressure will stay in place Sunday through Wednesday. Heat and high humidity will be the main story through these four days. High temperatures will reach the middle to upper 90s with one or two days reaching the lower 100s in some places, especially near the metros and eastern zones.
Heat indices will reach the 100 to 105 degree range in many places with a few places reaching near or at 110 degrees.
