ward to a closing-off low in southwest Missouri.
The last of the rain is exiting southern Maryland. However, there`s another batch in southwestern Virginia. This should slide along the southern portion of the CWA during the middle of the night, with drier air winning the battle farther north. After this rain exits, there could be another break late tonight into early Sunday morning.
Lower clouds have been clearing out of northern portions of the area, although the lower dew points are lagging in PA. With the thin clouds and rain-saturated conditions, there could be a little fog before drier air advects in (already seeing some reductions in visibility at MRB and OKV). Lows tonight will be in the 40s for most locations.
During the day Sunday, it now appears that drier Canadian air will press southward far enough to dry us out. The northern half of the area may even see filtered sun through cirrus for the first half of the day, with cloudier conditions south. The overrunning rain due to the proximity of the frontal zone will persist across the far south (central VA and southern MD), but it should be light in nature as the best deep moisture will be suppressed in southern VA. Highs will be coolest in the south in the mid 50s, but perhaps poking into the 60s in the north.
SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/... Closed low aloft and associated surface system will continue sliding east across the southern US Sunday night, then turn northeast up the Atlantic Coast by Monday night. This will cause rain to overspread the region again, with temperatures remaining cool. An increasing northeast wind as the surface low strengthens will add to the rather uncomfortable weather, especially compared to recent warmth. Significant rain is possible, perhaps 1 to 3 inches. If heavy rainfall becomes concentrated, it is possible some flooding could occur, but right now, given it has generally been dry and there remains great model inconsistency about where any heavy rain may ultimately fall, do not have any plans for flood watches yet. This will no doubt be revisited by future shifts.
LONG TERM /TUESDAY THROUGH SATURDAY/... Coastal low pressure will track north along the Carolina coastline Tuesday. Forecast guidance depicts a broad area of precipitation with this system as the upper level low is nearly stacked on the coastal low. Rain is expected across the region Tuesday into Tuesday night. Bands of heavier rain are possible during this time as easterly LLJ pumps moisture into the Mid- Atlantic. Stable conditions expected with temperatures in the 50s/60s.
The coastal low will be off the Delmarva coastline Wednesday and rain will come to an end across the Mid-Atlantic region. Sunshine will help temperatures get closer to 70 on Wednesday. Winds become southerly Wed night ahead of the next cold front. A cold front will pass the region Thu-Fri and showers and thunderstorms are possible. Temperatures will become above normal Thu-Fri.
