Synopsis for the tidal potomac and md portion of the chesapeake bay.. Weak area of high pressure will continue to move away tonight into Monday allowing for the next disturbance to migrate in Tuesday. Multiple areas of low pressure are expected to move across the area during the middle portion of the week. Small craft advisories may be needed for portions of the waters through the middle of the week.

Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 906 PM EDT Sun Sep 27 2020

SYNOPSIS. A ridge of high pressure will remain over the region tonight. A cold front will move across the area late Tuesday night followed by a second reinforcing cold front Friday. High pressure will build over the region toward the end of the week.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/. An upper level trough will move across the area tonight before exiting to our northeast shortly after daybreak Monday. High clouds will be the main story overnight. However, these high clouds may not be enough to deter patchy dense fog from forming across much of the western third of our region later tonight into early Monday.

SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY NIGHT/. Areas mainly west of I-95 could encounter patchy dense fog to start the day Monday. A couple of locations could have visibility greatly reduced once again along and west of I-81.

Once any fog burns off and the southerly wind increases later Monday morning, we will introduce the threat for showers Monday afternoon. Most of the shower activity through mid- afternoon should be over the mountains in the west with a couple forming closer to I-95. Temperatures will be a couple of degrees warmer with increasing humidity too.

As a cold front approaches Monday night, the chance for showers initially declines as instability wanes, before increasing again late from west to east. As we transition from Monday night into Tuesday, the cold front is expected to push halfway into our CWA prior to possibly stalling somewhere along the Blue Ridge Mountains Tuesday afternoon. This could set the stage for multiple rounds of showers with a couple embedded thunderstorms Tuesday night. Rain amounts appear to be modelled heaviest along and east of I-95, particularly across southern Maryland.

LONG TERM /WEDNESDAY THROUGH SUNDAY/. On Wednesday morning, a fairly pronounced baroclinic zone will be in the process of moving across the I-95 corridor. Multiple waves of low pressure are primed to ride along this boundary, each being an impetus to local heavy rainfall production. Global ensembles, mainly the 12Z GEFS and 00Z ECMWF ensemble show the highest precipitation probabilities along and east of I-95. These particular ensembles favor a broad 1 to 2 inches of rainfall through early Thursday. Although the guidance differ with the timing and overall forecast track, this system should be quite dynamic, particularly as it attains a negative tilt over the Carolinas on Wednesday. Ample diffluence aloft will be coupled with seasonably high tropospheric moisture content. Forecast precipitable water values range from 1.50 to 1.75 inches which is above the 95th percentile for late September. At this juncture, the Weather Prediction Center has the entire region highlighted in the Day 3 Excessive Rainfall Outlook which runs into Wednesday. Difficult to predict hydrologic impacts this far out, but some instances of flooding are possible. Some rumbles of thunder will also be possible with a few of the stronger convective elements.

Precipitation may linger into early Thursday as models have been trending slower with the track of the closed low. In the wake of this system, persistent cyclonic flow will ensure a pronounced cool down to close out the week. While 1000-500 dm thicknesses and 850-mb temperatures begin to decrease/cool on Thursday, deep-layered westerly flow will maintain a well-mixed boundary layer. This should keep highs in the upper 60s to low 70s before further cooling ensues thereafter. Multiple mid-level perturbations traversing the cyclonic flow could bring scattered high elevation showers through Friday. High temperatures heading into the weekend will likely run in the low/mid 60s with overnight readings down into the 40s.

AVIATION /01Z MONDAY THROUGH FRIDAY/. VFR across the region presently. However, low cigs and vsby expected as low clouds/fog redevelop, though coverage and intensity look to be reduced compared to Sunday morning. Highest odds are west, beyond the terminals, but could easily encroach on MRB and CHO with IFR conditions. MVFR is the more likely limit locally, though DCA has a decent chance of staying VFR.

Monday will start out with sub-VFR conditions as most terminals. Once the fog/low clouds burn off, we start seeing more scattered showers developing from west to east through the afternoon.

Chances of rain showers diminish Monday evening before increasing again late Monday night through Tuesday night with isolated thunderstorms also possible. Sub VFR conditions likely with showers and thunderstorms.

Sub-VFR visual flight rules are possible on Wednesday given the expectation of lower ceilings and visibilities as a frontal zone moves through. Further reductions may occur within heavier showers along with locally gusty winds. Such conditions could linger into early Thursday given timing differences in the models.

MARINE. Lights winds overnight. A small craft advisory is in effect for late Monday morning through Monday afternoon. Additional small craft advisories may be needed as a southerly flow becomes more pronounced Monday night through Tuesday night.

Occasionally breezy west to northwesterly winds may lead to reaching Small Craft Advisory criteria on Wednesday while possibly continuing into Thursday.

EQUIPMENT. The KLWX (Sterling, VA) WSR-88D remains out of service until further notice. The outage is due to a failure within the Radar Data Acquisition Functional Area that occurred early in the morning on September 20, 2020.

Saturday morning, technicians from the National Weather Service Radar Operations Center diagnosed a failure in the bull-gear. This will cause a lengthy delay in returning KLWX WSR-88D to service. Staff from the WSR-88D Radar Operations Center, NWS Eastern Region Headquarters, and the Baltimore/Washington Weather Forecast Office (WFO) will meet Monday, September 28 to determine the next steps. At that time, we will provide you with another update on the repair and expected time to return KLWX to service. At this point, the radar will be out of service for at least another week or two.

Users of KLWX can utilize adjacent weather radars located in Dover DE (KDOX), Mt. Holly NJ (KDIX), Pittsburgh PA (KPBZ), Charleston WV (KRLX), Blacksburg VA (KFCX), and Wakefield VA (KAKQ).

Further updates to keep users informed about the situation will be issued as information becomes available. Thank you for your understanding during this extended outage.
