SYNOPSIS... High pressure will remain centered off the Mid-Atlantic coast through Friday. A cold front will cross the area Saturday. High pressure then builds over the area through Sunday. Another cold front will move through the area Monday night or Tuesday.
NEAR TERM /THROUGH FRIDAY/...
More record high temperatures broken today - 77 at IAD broke their record by 4 degrees.
The pressure gradient increases overnight, so south winds should continue. However, with clearing skies any areas that decouple could fog up, particularly locations that see rain showers. Min temps generally low to mid 50s (near afternoon dewpoints).
SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... Quiet, sunny, and very warm again Friday. South winds 10 to 15 mph with max temps upper 70s to 80F again.
Cold frontal passage from west to east Saturday. Strong, gusty showers and scattered thunderstorms are expected. Max temps just before the front with most areas reaching the 70s again, mid 70s possible in southern Maryland. Generally a quarter inch rainfall expected, higher amounts in the heaviest showers/thunderstorms.
Four to six hour strong gust window behind the cold front Saturday evening. Wind advisories do not look necessary, but widespread 35 to 40 mph gusts are likely.
Upslope snow begins at the highest elevations late Saturday afternoon with up to an inch above 3500 ft and a dusting as low as 2000ft west of the Allegheny Front.
LONG TERM /SUNDAY THROUGH THURSDAY/... A dome of high pressure will build into the region Sunday and Sunday night. Temperatures will be 15 to 20 degrees cooler through the period. Consider what we`ve been experiencing these temperatures could be classified as "normal."
As the high moves offshore Monday, a storm system will move parallel to the Ohio Valley and push into the mid-Atlantic later in the day. A chance of rain and snow showers are possible with the storm system. If the storm tracks farther south, then precipitation could become more of a light snow event.
The storm will move offshore Monday night as high pressure builds in behind the storm system through Tuesday evening. Dry and seasonably cool temperatures expected through the period.
The high will move northeast and offshore the New Jersey Coast overnight Tuesday into early Wednesday. Some light rain could move in from the southwest ahead of a warm front late at night and early Wednesday.
A warm front should move north of the region Wednesday, as showers and perhaps a rumble of thunder develop ahead of an approaching cold front later Wednesday afternoon. Springlike-temperatures could evolve in this warm sector of the storm system.
As the main trough of low pressure pivots across the region Wednesday night and Thursday, cooler and drier air will follow with high pressure building in from the west. Some upslope snow showers could evolve as well through the day Thursday.
