Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 309 PM EDT Fri Jun 1 2018 .SYNOPSIS... A cold front will approach the region from the northwest later today and stall nearby through Saturday. Low pressure will develop along the front off of the Virginia coast late Saturday and remain into Sunday. Low pressure will move away Monday, another front approaches Tuesday and high pressure builds behind it through mid week. && .NEAR TERM /THROUGH TONIGHT/... A lot of more sunshine today than the past couple of days as clouds have break over most of our area. A generally light flow is observed over our region with a quiet radar at this moment. Precipitable water is expected to remain around 1.5 to 2 inches this afternoon and into the evening hours while a shortwave axis approaches our area into tonight. In terms on CAPE, values are decent between 1000 to 2000 J/kg, the shear is minimal. Looking into a late afternoon start on precip for areas west and progressing east into the metro areas in the evening hours, not too confident on anything severe. However, heavy rain is still possible. && .SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/... On Saturday trough axis pushes through our area and low pressure develops off of the Virginia coast. Guidance is still in disagreement on how deep the trough and the upper low is and when it reflects at the surface. Surface low stalls and intensifies off of the coast Saturday into Sunday. Rain showers and thunderstorms are still possible both days, especially enhanced with diurnal heating. Thunderstorms most likely Saturday but depending how soon precipitations starts. As the system stalls off of the coast, we are looking into slow moving storms and with PWAT between 1.5 and 2 inches, heavy rain is possible and flood concerns continue. Northerly flow will be advecting colder air into our region during the weekend. High temperatures will be near 80 on Saturday and near 70 on Sunday. && .LONG TERM /MONDAY THROUGH FRIDAY/... On Monday morning, the aforementioned surface low will be somewhere off of the Delmarva Peninsula. This will still allow for some moisture flow off the Atlantic, bringing a continued chance for some showers. The difference among the deterministic models is the location of another strong upper level system moving out of the Great Lakes. The European deterministic model suggests that this upper level feature should slide just to our north, with rain chances ending Monday around midday. However, the GFS brings this system a little farther south, allowing for it to absorb the previous upper low over Delmarva to the north, and the associated surface low along with it. Essentially, this would mean a more extended period of rain chances through Monday evening. However, neither really hints at heavy rain potential, but rather just scattered showers. Temperatures will remain below average, with highs only in the middle 70's. A surface low, associated with the aforementioned strong upper low, will dive out of Ontario into the northeast on Tuesday. This should drag a cold front across the region Tuesday afternoon. Models vary on whether or not there will be showers associated with this front, but even those that do show rain have very little accumulation. High temperatures will remain below average, with highs only slightly warmer than on Monday. High pressure finally returns to the region Wednesday and Thursday, in the wake of the cold front. This should bring a period of dry weather to the region. A gradual warming trend will begin through the end of the long term period, with upper 70's possible for high temperatures by Thursday. && .AVIATION /FRIDAY THROUGH WEDNESDAY/... VFR conditions observed over most terminals this afternoon. Expecting conditions to remain VFR until showers and thunderstorms arrive late this afternoon/evening with a scattered coverage and increasing into the night hours. More numerous showers are expected on Saturday and into Sunday, therefore more widespread restrictions are possible. Hard to specify timing of restrictions this far out. On Monday and Tuesday, expect VFR conditions throughout the period. && .MARINE... Winds are expected to remain below small craft criteria this afternoon, overnight and into Saturday with showers/thunderstorms possible. Winds will be on the increase Saturday night as a low pressure system intensifies offshore. This may require a small craft advisory over the waters. Winds will be decreasing on Sunday night. For Monday and Tuesday, expect winds to stay below SCA criteria. && .LWX WATCHES/WARNINGS/ADVISORIES... DC...None. MD...None. VA...None. WV...None.
