... A cold front will cross the area late tonight into Friday, then move into the Carolinas over the weekend. Canadian high pressure will build north of the region over the weekend as low pressure forms off the southeast coast and slides by near or east of the area Monday into Tuesday.
NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... There is currently ongoing convection over portions of Maryland... mainly near the Baltimore metro area and over the northern portion of the Chesapeake Bay. This main area will continue to move east-southeast away from us with some lingering showers/thunderstorms continuing over the next hours.
A cold front sits to our north and is expected to continue to move southeastward and into our CWA. This will continue the chance of scattered showers overnight across portions of the region. Lows will range through the 60s to low 70s.
SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/... The front will continue its track southward through the day Friday and likely be nearing the NC/VA border by the evening. However strong southwest flow will remain aloft with upper level energy traversing the region, so rain showers are likely, especially across central/western VA, into the mid afternoon hours. A few thunderstorms with locally heavy rain are possible as well. Otherwise, mostly cloudy skies and cooler temperatures are expected. Highs from the upper 70s to around 80F.
Cool and dry air will continue its progression southward into the region Friday night. Lows will drop into the upper 50s to mid 60s.
A ridge of high pressure will be in control on Saturday with mostly sunny skies and highs in the upper 70s to low 80s. Lows Saturday night will once again be in the upper 50s to mid 60s.
LONG TERM /SUNDAY THROUGH THURSDAY/... High pressure will be set up across the northeast on Sunday, resulting in relatively dry and cooler than average temperatures. Highs will only reach the upper 70s/low 80s. With a departing upper low, and onshore low-level flow, can't rule out a shower or some drizzle on Sunday.
On Monday and Tuesday, the forecast is a bit murky at this point. Ridging along the eastern seaboard will lead to the formation of a stationary front along the east coast. Meanwhile, a weak wave of low pressure will be moving out of the Caribbean and up the southeastern coast Sunday into Monday, resulting in the formation of a surface low pressure system somewhere along the southeast coast. This is actually the disturbance that the National Hurricane Center has outlooked for potential development along the east coast. Then, it is all a matter of where this low tracks, and what form the low takes. The GFS brings the low relatively close the Delmarva Peninsula, meaning more rain for our eastern zones. Meanwhile, the Euro keeps the low farther offshore, but still brings a chance for showers to eastern areas due to onshore surface flow. To sum this up, there is a lot of uncertainty in this portion of the forecast until we start to see the pieces fall into place, which just hasn't happened yet. But depending on how this coastal low develops (still some uncertainty if it will become tropical/subtropical in nature), and which direction it moves, the forecast could change drastically in the coming days. For now, will keep chance POPs in the forecast, with a slight potential for some embedded thunderstorms. Monday and Tuesday should remain near to slightly below average in terms of temperatures, with highs in the low 80s.
On Wednesday, showers and thunderstorm chances increase due to an approaching cold front. This should also push the coastal low off to the north and east (if it does indeed track up our way). Regardless, yet another afternoon with showers and storms across the region.
